Ruxolitinib for vitiligo: Experts share experiences from first year
.
The Food and Drug Administration approved the cream formulation of ruxolitinib (Opzelura), a JAK inhibitor, for repigmentation of nonsegmental vitiligo in July 2022 for people aged 12 years and older.
Raj Chovatiya, MD, PhD, assistant professor of dermatology at Northwestern University, Chicago, said that he likes to use ruxolitinib cream in combination with other treatments.
“In the real world with vitiligo patients, we’re oftentimes doing combinatorial therapy anyway. So phototherapy, specifically, narrow-band UVB, is something that we have a lot of clinical evidence for over the years, and it’s a modality that can combine with topical steroids and topical calcineurin inhibitors.”
He said trials to study combinations will yield better guidance on optimal use of ruxolitinib cream. “In general, vitiligo patients can really benefit from phototherapy,” he said in an interview. (Labeling recommends against combination with other JAK inhibitors, biologics, or potent immunosuppressants, such as azathioprine or cyclosporine.)
This first year has shown that ruxolitinib is an effective option, but counseling patients to expect slow improvement is important so that patients stick with it, he noted.
Documenting what treatments patients with vitiligo have used before is important, he said, as is counseling patients that ruxolitinib is approved only for use on up to 10% of a person’s body surface area. (Product labeling recommends that a thin layer be applied twice a day to affected areas up to 10% of body surface area.)
Ruxolitinib has brought a “louder voice” to vitiligo and has opened up options for patients with the disease, Dr. Chovatiya said. “Having the ability to topically treat people who have very extensive disease really gives us a lot more flexibility than we have had before.”
Good experiences with payers at safety-net hospital
Candrice R. Heath, MD, assistant professor of dermatology at Temple University, Philadelphia, said that real-world experience with topical ruxolitinib will be more evident after its been on the market for 18-24 months.
Dr. Heath said she, too, encourages use of narrow-band UVB phototherapy in conjunction with the treatment.
From an insurance reimbursement standpoint, she said that she is glad that there have been fewer hurdles in getting ruxolitinib to patients than she has experienced with other medications.
In her safety-net hospital, she told this news organization, she sees patients with many types of insurance, but most have Medicaid. “So, I’m always expecting the step therapies, denials, pushbacks, etc.,” she said. But the path has been smoother for ruxolitinib coverage, she noted.
Her colleagues are committed to documenting everything the patient has tried, she added, and that helps with prior authorization.
Dr. Heath said that pointing out to insurers that ruxolitinib is the only approved treatment for repigmentation helps facilitate coverage.
“The science is advancing, and I’m happy to be practicing during a time when we actually have something approved for vitiligo,” she said. But she pointed out that phototherapy often is not covered for vitiligo, “which is horrible, when it is readily approved for psoriasis and atopic dermatitis.”
To document progress, Dr. Heath said that she always takes photographs of her patients with vitiligo because “the pictures remind us how far we have come.”
Data spotlight success in adolescents
Data from two trials give a clinical picture of the drug’s safety and efficacy in younger patients.
Adolescents had particularly good results in the first year with ruxolitinib, according to pooled phase 3 data from TRuE-V1 and TRuE-V2, this news organization reported.
The findings, presented at the 25th World Congress of Dermatology in Singapore, indicate that more than half of the participants achieved at least a 50% improvement from baseline in the total Vitiligo Area Scoring Index (T-VASI50) at 52 weeks.
The percentages of young patients aged 12-17 years taking twice-daily ruxolitinib who achieved T-VASI 50 at weeks 12, 24, and 52 were 11.5%, 26.9%, and 57.7%, respectively. The corresponding percentages for all in the study population were 10.7%, 22.7%, and 44.4%, respectively.
At the meeting, the presenter, Julien Seneschal, MD, PhD, professor of dermatology and head of the vitiligo and pigmentary disorders clinic at the University of Bordeaux, France, said, “This suggests that younger patients can respond better to the treatment.” He noted, however, that there were few adolescents in the studies.
New excitement in the field
Daniel Gutierrez, MD, assistant professor of dermatology at New York University, said the treatment has brought new excitement to the field.
“Patients with vitiligo are very motivated to treat their disease,” he said, because it typically is on the face and other highly visual areas, which can affect their overall perception of self.
Previously, he noted in an interview, the only FDA-approved treatment was monobenzone, but that was for depigmentation rather than repigmentation.
Otherwise, treatments were being used off label, and patients were receiving compounded formulations that often weren’t covered by insurance and often had shorter shelf life.
He said that he still occasionally gets denials from payers who consider vitiligo a cosmetic condition.
“I’ve had more luck with insurance, at least in the New York State area.” He added that sometimes payers require use of a topical calcineurin inhibitor for about 12 weeks before they will cover ruxolitinib.
Dr. Gutierrez also recommends using phototherapy with topical ruxolitinib “because they work on slightly different pathways.”
When he starts patients on a new therapy such as ruxolitinib, he asks them to come back in 3 months, and often by then, progress is evident. Facial areas show the most response, he said, while hands and feet are less likely to show significant improvement.
He said that it’s important for physicians and patients to know that improvements can take weeks or months to be noticeable. “I tell patients not to give up,” he added.
Showing the patients pictures from the current appointment and comparing them with pictures from previous appointments can help them better understand their progress, he said.
Lead investigator adds observations
David Rosmarin, MD, chair of the department of dermatology at Indiana University, Indianapolis, was the lead investigator of the pivotal TruE-V1 and TruE-V2 trials for vitiligo. In that role, he has been treating vitiligo patients with topical ruxolitinib since 2015.
In an interview, he said that many patients “don’t hit their optimal results at 3 months, 6 months, even the year mark. With continued use, many can see continued benefit.”
Other patients, he said, don’t respond within the first 6 months but with continued use may eventually respond, he said.
“Unfortunately, we have no way of knowing, based on clinical characteristics or baseline demographics, whether a patient will be a delayed responder or not or an early responder,” Dr. Rosmarin added.
He provided several observations about people who have stopped taking the medication.
“When people stop,” he said, “some maintain their response, but some start to depigment again. Again, we have no way of predicting who will be in which category.”
He said that once patients have hit their desired response, he usually advises them to taper down to maybe twice a week or to stop treatment, but if they see any recurrence, they should start reusing the medicine.
“We have some patients who have gone 6 or 7 years now before they had a recurrence, but others may start to depigment again in 2 to 3 months,” Dr. Rosmarin said.
As for phototherapy, he said, the combination with topical ruxolitinib is being studied.
“We think the combination is synergistic and better than either alone, but we’re still waiting for data to prove that,” he said.
In his practice, he offers patients the option either to use just ruxolitinib cream or the combination early on. Many patients, because of convenience, say they’ll first try the cream to see if that works.
“The challenge with light [therapy] is that it can be very inconvenient,” he said. Patients have to live close to a phototherapy unit to receive therapy 2-3 times a week or have a phototherapy product in their home.
Next in the pipeline
Experts say the progress doesn’t stop with ruxolitinib cream. Current trials of several medications show there’s more to come for patients with vitiligo.
Dr. Chovatiya said that next up may be oral ritlecitinib (Litfulo), a JAK inhibitor that was approved for severe alopecia areata in June for people aged 12 years and older. Phase 2 results have been published for its use with vitiligo.
“This would be an oral medication that may be able to help people with much more extensive disease as far as vitiligo goes,” he said, adding that he expects approval for a vitiligo indication within a few years.
He pointed out that longer-term safety data will be available because it is already on the market for alopecia.
Upadacitinib (Rinvoq), an oral JAK inhibitor, is approved for atopic dermatitis but is being studied for vitiligo as well, he noted. “I’m very excited to see what that holds for patients as well,” Dr. Chovatiya said.
Dr. Gutierrez said that he is excited about oral JAK inhibitors but sees potential in finding new ways to transplant melanocytes into areas where there are none.
The pigmentation field has seen new energy since last year’s approval, he said, particularly among people of color.
“We have new options for vitiligo that were lacking compared with other conditions, such as atopic dermatitis and psoriasis,” he said. “Hopefully, there will be more promising breakthroughs.”
Dr. Rosmarin is the chief investigator for the pivotal trials that led to FDA approval of ruxolitinib. He disclosed ties with AbbVie, Abcuro, AltruBio, Amgen, Arena, Boehringer Ingelheim, Bristol-Meyers Squibb, Celgene, Concert, CSL Behring, Dermavant, Dermira, Galderma, Incyte, Janssen, Kyowa Kirin, Lilly, Merck, Novartis, Pfizer, Regeneron, Revolo Biotherapeutics, Sanofi, Sun Pharmaceuticals, UCB, and Viela Bio. Dr. Chovatiya disclosed ties with AbbVie, Arcutis, Arena, Argenx, Beiersdorf, Bristol-Myers Squibb, Dermavant, Eli Lilly, EPI Health, Incyte, LEO Pharma, L’Oréal, National Eczema Association, Pfizer, Regeneron, Sanofi, and UCB. Dr. Heath and Dr. Gutierrez report no relevant financial relationships.

Diabetes drug class appears to reduce recurrent gout flares
The glucose-lowering drug class sodium-glucose cotransporter 2 (SGLT2) inhibitors appear to reduce the risk for recurrent gout flares in people with gout and type 2 diabetes, and to lessen excess mortality in those individuals, compared with those who initiated other types of glucose-lowering medications, new data suggest.
Among nearly 6,000 adults with both type 2 diabetes and gout from a U.K. primary care database, initiation of SGLT2 inhibitor treatment was associated with 19% fewer recurrent gout flares and 29% lower mortality.
Moreover, unlike other urate-lowering therapies, there were no apparent transient increases in the risk of gout flares after initiating therapy, Jie Wei, PhD, of Health Management Center, Xiangya Hospital, Central South University, Changsha, China, and colleagues reported in JAMA Network Open.
These results are important because current management of gout is suboptimal. Many patients either don’t receive adequate urate-lowering therapies such as allopurinol or stop taking them, Dr. Wei and colleagues said.
In addition to lowering glucose, SGLT2 inhibitors also reduce the risk for major adverse cardiovascular events and all-cause mortality in people regardless of their diabetes status. Previous studies have also found that SGLT2 inhibitors reduce the risk for developing gout and of gout flares.
Asked to comment, gout specialist John D. FitzGerald, MD, PhD, clinical chief of rheumatology at the University of California, Los Angeles, said in an interview: “I think it’s a well-done paper, with a large dataset. I think it just reinforces the findings from the other papers. Mostly anything that lowers uric acid levels is going to lower recurrent gout attacks, so it all makes sense.”
However, while Dr. FitzGerald thinks the drug class is a good option for people with diabetes or cardiorenal indications for them who also have gout, he doesn’t envision it as first-line for most other patients with gout. “The current treatments are very effective. Allopurinol brings down uric acid levels by 5-7 points. There are patients who fail allopurinol, but those are less than 5%.”
The most common reason patients stop taking allopurinol is the frequent initial gout flare. But that’s preventable, Dr. FitzGerald said, either by titrating up slowly, or by adding colchicine along with it. “By going slowly, you can avoid that flare risk. I think that’s what’s going on with the SGLT2 inhibitor. It’s not a dramatic urate-lowering drug, but it is clinically meaningful. I think that’s what this paper is showing.”
But, he noted, “I think there are so many reasons to start the SGLT2 inhibitors that if somebody also has gout, all the better. And, if somebody is on the margin with diabetes and gout control and can’t go with allopurinol, it would be great to add for both conditions.”
Less gout recurrence, lower mortality
The retrospective study was conducted from Jan. 1, 2013, to March 31, 2022. Among 5,931 patients with both type 2 diabetes and gout, 1,548 (26.1%) initiated an SGLT2 inhibitor (dapagliflozin, empagliflozin, or canagliflozin), while 4,383 (73.9%) initiated treatment with other active comparators, mostly (92.6%) dipeptidyl peptidase–4 inhibitors.
Gout flares were identified in the charts for a total of 86% of the participants. The weighted incidence rates for the first recurrent flare were 32.4 versus 41.2 per 1,000 person-years in the SGLT2 inhibitor versus comparator groups, with a weighted absolute rate difference of –8.8/1,000 and weighted hazard ratio of 0.81, a significant difference.
All-cause mortality was 18.8 versus 24.9 per 1,000 person-years, respectively, giving an HR of 0.71 at 5-year follow-up.
Dr. FitzGerald, who chaired the American College of Rheumatology’s 2020 gout guidelines, said he anticipates that the SGLT2 inhibitors will be mentioned in the next update to the ACR’s now “living” guidelines, although he was not speaking on the organization’s behalf.
“We talk about losartan in the current [ACR guidelines], about its specific uric acid–lowering effect. Drugs can make uric acid worse or better. For example, thiazides make it higher. I think the SGLT2 [inhibitors] are important, but I don’t think they’re huge. The study is great, and I think the drugs are great, but I don’t think they will change the way gout is managed.”
This work was supported by grants from the National Key Research and Development Plan, the National Natural Science Foundation of China, the Project Program of National Clinical Research Center for Geriatric Disorders, and from the Natural Science Foundation of Hunan Province. Dr. Wei reported receiving grant funding from Xiangya Hospital Central South University Project Program of National Clinical Research Center for Geriatric Disorders and the Science and Technology Department of Hunan Province, the Natural Science Foundation of Hunan Province, during the conduct of the study. Dr. FitzGerald reported no relevant financial relationships.

The glucose-lowering drug class sodium-glucose cotransporter 2 (SGLT2) inhibitors appear to reduce the risk for recurrent gout flares in people with gout and type 2 diabetes, and to lessen excess mortality in those individuals, compared with those who initiated other types of glucose-lowering medications, new data suggest.
Among nearly 6,000 adults with both type 2 diabetes and gout from a U.K. primary care database, initiation of SGLT2 inhibitor treatment was associated with 19% fewer recurrent gout flares and 29% lower mortality.
Moreover, unlike other urate-lowering therapies, there were no apparent transient increases in the risk of gout flares after initiating therapy, Jie Wei, PhD, of Health Management Center, Xiangya Hospital, Central South University, Changsha, China, and colleagues reported in JAMA Network Open.
These results are important because current management of gout is suboptimal. Many patients either don’t receive adequate urate-lowering therapies such as allopurinol or stop taking them, Dr. Wei and colleagues said.
In addition to lowering glucose, SGLT2 inhibitors also reduce the risk for major adverse cardiovascular events and all-cause mortality in people regardless of their diabetes status. Previous studies have also found that SGLT2 inhibitors reduce the risk for developing gout and of gout flares.
Asked to comment, gout specialist John D. FitzGerald, MD, PhD, clinical chief of rheumatology at the University of California, Los Angeles, said in an interview: “I think it’s a well-done paper, with a large dataset. I think it just reinforces the findings from the other papers. Mostly anything that lowers uric acid levels is going to lower recurrent gout attacks, so it all makes sense.”
However, while Dr. FitzGerald thinks the drug class is a good option for people with diabetes or cardiorenal indications for them who also have gout, he doesn’t envision it as first-line for most other patients with gout. “The current treatments are very effective. Allopurinol brings down uric acid levels by 5-7 points. There are patients who fail allopurinol, but those are less than 5%.”
The most common reason patients stop taking allopurinol is the frequent initial gout flare. But that’s preventable, Dr. FitzGerald said, either by titrating up slowly, or by adding colchicine along with it. “By going slowly, you can avoid that flare risk. I think that’s what’s going on with the SGLT2 inhibitor. It’s not a dramatic urate-lowering drug, but it is clinically meaningful. I think that’s what this paper is showing.”
But, he noted, “I think there are so many reasons to start the SGLT2 inhibitors that if somebody also has gout, all the better. And, if somebody is on the margin with diabetes and gout control and can’t go with allopurinol, it would be great to add for both conditions.”

How to optimize in-hospital antimicrobial prescribing?
Variability in antimicrobial prescribing among hospital-based physicians is not associated with patient characteristics or clinical outcomes, data suggest. The lowest level of such prescribing within each hospital could be considered a target for antimicrobial stewardship, according to the researchers.
In a multicenter study of 124 physicians responsible for more than 124,000 hospitalized patients, the difference in mean prescribing between the highest and lowest quartiles of prescription volume was 15.8 days of treatment per 100 patient-days.
Baseline patient characteristics were similar across the quartiles, and there were no differences in patient outcomes, including in-hospital deaths, hospital length of stay, intensive care unit transfer, and hospital readmission.
Although the investigators expected variation in prescribing, “what surprised us most was the limited association with any differences in clinical outcomes, particularly when it came to the amount of antimicrobials used,” study author Mark T. McIntyre, PharmD, pharmacotherapy specialist at the Sinai Health System in Toronto, told this news organization.
“Importantly, this is not a study that defines quality of care,” he said. “We looked at natural variation in practice and association with outcomes. So, I don’t want clinicians to think, ‘Well, I’m high, therefore I’m bad,’ or, ‘I’m low, therefore I’m good.’
“This is an early explanatory analysis that asks whether this is an opportunity to optimize prescribing in ways we hadn’t thought of before,” he said. “Now that we don’t have an association with higher or lower prescribing and outcomes, we can look at what else is driving that antimicrobial prescribing and what we can do about it. Comfort level, risk tolerance, and social, cultural, and contextual factors all likely play a role.”
The study was published online in the Canadian Medical Association Journal.
Antimicrobial reductions possible
The investigators conducted a retrospective cohort study using the General Medicine Inpatient Initiative database to assess physician-level volume and spectrum of antimicrobial prescribing in adult general medical wards. Four academic hospitals in Toronto were evaluated for the period 2010 to 2019.
The investigators stratified physicians into quartiles by hospital site on the basis of volume of antimicrobial prescribing (specifically, days of therapy per 100 patient-days and antimicrobial-free days) and antibacterial spectrum (modified spectrum score, which assigns a value to each antibacterial agent on the basis of its breadth of coverage).
They also examined potential differences between physician quartiles in patient characteristics, such as age, sex, the Laboratory-Based Acute Physiology Score, discharge diagnosis, and the Charlson Comorbidity Index.
Multilevel modeling allowed the investigators to evaluate the association between clinical outcomes and antimicrobial volume and spectrum.
The primary measure was days of therapy per 100 patient-days.
As noted, the cohort included 124 physicians who were responsible for 124,158 hospital admissions. The median physician-level volume of antimicrobial prescribing was 56.1 days of therapy per 100 patient-days. Patient characteristics were balanced across the quartiles of physician prescribing.
The difference in mean prescribing between physician quartile 4 and quartile 1 was 15.8 days of therapy per 100 patient-days, meaning the median physician in quartile 4 prescribed antimicrobials at a volume that was 30% higher than that of the median physician in quartile 1.
No significant differences were noted for any clinical outcome with regard to quartile of days of therapy, antimicrobial-free days, or modified spectrum score after adjustment for patient-level characteristics.
In addition, no significant differences in the case mix between quartile 4 and quartile 1 were found when the cohort was restricted to patients admitted and discharged by the same most responsible person, nor were differences found in an analysis that was restricted to those without a discharge diagnosis code of palliative care.
In-hospital mortality was higher among patients cared for by prescribers with higher modified spectrum scores (odds ratio, 1.13). “We still can’t fully explain this finding,” Dr. McIntyre acknowledged. “We only saw that in our primary analysis. When we did several sensitivity analyses, that finding didn’t appear.”
The authors concluded, “Ultimately, without discernible benefit in outcomes of patients of physicians who prescribe more frequently, less antimicrobial exposure may be possible, leading to lower risk of antimicrobial resistance.”
Decision-making support
Commenting on the study, Lawrence I. Kaplan, MD, section chief of general internal medicine and associate dean for interprofessional education at the Lewis Katz School of Medicine at Temple University in Philadelphia, said, “Trying to get to the lowest quartile would be a goal, and given that physician characteristics are involved, I think there needs to be much better training in clinical management decision-making: how you come about making a decision based on a diagnosis for a particular patient, in or out of the hospital.” Dr. Kaplan was not involved in the research.
“Clinical decision-making tools that can be plugged into the electronic health record can help,” he suggested. “The tools basically ask if a patient meets certain criteria and then might give a prompt that says, for example, ‘These symptoms are not consistent with bacterial sinusitis. The patient should be treated with decongestants, nasal steroids, et cetera, because antibiotics aren’t appropriate.’
“It’s a bit like checkbox medicine, which a lot of physicians bridle at,” he said. “But if it’s really based on evidence, I think that’s an appropriate use of evidence-based medicine.”
Dr. Kaplan said that more research is needed into the best way to get a physician or any provider to step back and say, “Is this the right decision?” or, “I’m doing this but I’m really on shaky ground. What am I missing?’” He noted that the Society for Medical Decision Making publishes research and resources in this area.
“I love the fact that the paper was authored by an interdisciplinary group,” Dr. Kaplan added. “A pharmacist embedded in the team can, for example, help with treatment decision-making and point out potential drug interactions that prescribers might not be aware of.
“We need to stop practicing medicine siloed, which is what we do a lot of ways, both in the hospital and out of the hospital, because it’s the path of least resistance,” Dr. Kaplan added. “But when we can say, ‘Hey, I have a question about this,’ be it to a computer or a colleague, I would argue that we come up with better care.”
No funding was provided for the study. Dr. McIntyre and Dr. Kaplan have disclosed no relevant financial relationships.

Probiotics improve nonmotor symptoms of Parkinson’s
COPENHAGEN – results of a new randomized trial show.
Participants taking the probiotic also saw a reduced delay in “time to on” of treatment with levodopa, thus reducing the delay until effectiveness of the treatment, said study presenter Valentina Leta, MD, PhD, department of neurosciences, King’s College London Institute of Psychiatry, Psychology and Neuroscience.
Dr. Leta presented the findings at the International Congress of Parkinson’s Disease and Movement Disorders.
“Virtually every person with Parkinson’s might have some degree of gastrointestinal dysfunction, and virtually the entire tract might be affected, from the mouth to the rectum,” Dr. Leta told attendees of the congress.
A number of different mechanisms have been associated with this gastrointestinal dysfunction, she noted, including proinflammatory changes in the gut microbiota, so a modulatory intervention “could be a therapeutic strategy for Parkinson’s disease.”
However, “despite numerous preclinical studies showing potential beneficial effects on a variety of pathological mechanisms involved in Parkinson’s disease, the clinical evidence is limited ... to the treatment of constipation,” she explained.
The team therefore conducted a multicenter, randomized, double-blind, placebo-controlled trial, in which patients with both Parkinson’s disease and constipation, based on the Rome IV criteria, were randomly assigned to receive a probiotic or placebo for 3 months.
The probiotic used was a liquid formulation (Symprove) and contained four strains: Lacticaseibacillus rhamnosus, Enterococcus faecium, Lactobacillus acidophilus, and Lactiplantibacillus plantarum.
A total of 74 patients were randomly assigned to the two study arms. The two groups were well matched for sociodemographics, Parkinson’s disease, and constipation-related characteristics, Dr. Leta reported, and only 3 patients in each arm discontinued the study. The probiotic intervention had a “good tolerability and safety profile, with a similar number of adverse events between the two groups, and no serious adverse events.”
Increase in healthy bacteria
The study met its primary outcome of changes in gut microbiome at the end of the 12-week intervention, as measured on shallow shotgun sequencing.
The probiotic was associated with a “statistically significant increase of the abundance of bacteria which are known to have beneficial health related properties, such as Odoribacteraceae,” Dr. Leta said.
This bacterium is “known to be reduced in people with Parkinson’s disease,” she explained, “and is involved in the production of short-chain fatty acids, which are known to have beneficial health-related properties.”
The secondary endpoint of the study included changes in motor and nonmotor symptoms, and the probiotic was associated with a significant improvement in the “time to on” with levodopa treatment, shortening this period from an average of 31.43 minutes at baseline to 23.95 minutes at the postintervention assessment (P < .027).
There was also a significant improvement in the Non-Motor Symptoms Scale (NMSS) score between baseline and the postintervention assessment in patients given the probiotic, from 70.71 to 61.34 (P = .005).
This, Dr. Leta observed, was “driven by improvements in the sleep, fatigue, and gastrointestinal domains.”
No such significant improvements were observed in the placebo arm.
Probiotics ‘hot topic’ among patients
Claudia Trenkwalder, MD, full professor of neurology at University Medical Center Goettingen (Germany), said in an interview that the use of probiotics is a “hot topic in Parkinson’s disease research, especially among patients.”
Dr. Trenkwalder, who was not involved in the study, noted that Lactobacillus strains “are established in Parkinson’s disease constipation treatment, with randomized controlled trials showing a significant improvement in constipation.
“Therefore, this is a useful treatment. The question here is: Do we have additional effects that can be measured in the microbiome and in clinical symptomatology?”
The trial showed that the probiotic studied “did alter the microbiome and did improve the constipation,” said Dr. Trenkwalder; however, the current data cannot prove whether the probiotic influenced the symptoms of Parkinson’s disease because the improvement in NMSS scores “is driven by the improvement in constipation.”
This, she argued, could have resulted in better absorption of levodopa.
A dietitian in the audience agreed. She asked whether the probiotic was doing anything “besides improving constipation,” adding that the resulting increased ability to absorb levodopa is also “going to help your sleep.”
Beyond constipation?
Dr. Leta replied that “we can assume that there is a link between the reduction in the ‘time to on’ and the improvement in constipation. We are doing some analyses in terms of levodopa pharmacokinetics to really understand the mechanisms behind this result.”
Although the improvement in constipation is “one of the possible hypotheses for the improvement in ‘time to on,’” she continued, “there is a more speculative one” in which the probiotics are modulating inflammatory parameters that could contribute to the improvement in sleep.
Veronica Bruno, MD, MPH, assistant professor in the department of clinical neurosciences at the University of Calgary (Alta.), commented in a press release that there has been “increasing interest” in examining the relationship between gut dysbiosis and the “gut-brain axis” in Parkinson’s disease.
The current study “stands out as a significant contribution to this area of study,” she said.
“While the implications of the observed changes in gut microbiota remain a captivating realm for further investigation, a particularly noteworthy finding revolves around the reduction in the ‘time to on’ observed within the active treatment group.”
Dr. Bruno said that shortening of the time to on “holds promise for substantial enhancements in patients’ lives” by reducing “difficult ‘off’ intervals and enhancing overall well-being.”
The study was funded by the UK National Institute for Health Research Mental Health Biomedical Research Centre and Dementia Unit at South London and Maudsley NHS Foundation Trust, and King’s College London. No relevant financial relationships were declared.

Participants taking the probiotic also saw a reduced delay in “time to on” of treatment with levodopa, thus reducing the delay until effectiveness of the treatment, said study presenter Valentina Leta, MD, PhD, department of neurosciences, King’s College London Institute of Psychiatry, Psychology and Neuroscience.
Dr. Leta presented the findings at the International Congress of Parkinson’s Disease and Movement Disorders.
“Virtually every person with Parkinson’s might have some degree of gastrointestinal dysfunction, and virtually the entire tract might be affected, from the mouth to the rectum,” Dr. Leta told attendees of the congress.
A number of different mechanisms have been associated with this gastrointestinal dysfunction, she noted, including proinflammatory changes in the gut microbiota, so a modulatory intervention “could be a therapeutic strategy for Parkinson’s disease.”
However, “despite numerous preclinical studies showing potential beneficial effects on a variety of pathological mechanisms involved in Parkinson’s disease, the clinical evidence is limited ... to the treatment of constipation,” she explained.
The team therefore conducted a multicenter, randomized, double-blind, placebo-controlled trial, in which patients with both Parkinson’s disease and constipation, based on the Rome IV criteria, were randomly assigned to receive a probiotic or placebo for 3 months.
The probiotic used was a liquid formulation (Symprove) and contained four strains: Lacticaseibacillus rhamnosus, Enterococcus faecium, Lactobacillus acidophilus, and Lactiplantibacillus plantarum.
A total of 74 patients were randomly assigned to the two study arms. The two groups were well matched for sociodemographics, Parkinson’s disease, and constipation-related characteristics, Dr. Leta reported, and only 3 patients in each arm discontinued the study. The probiotic intervention had a “good tolerability and safety profile, with a similar number of adverse events between the two groups, and no serious adverse events.”
Increase in healthy bacteria
The study met its primary outcome of changes in gut microbiome at the end of the 12-week intervention, as measured on shallow shotgun sequencing.
The probiotic was associated with a “statistically significant increase of the abundance of bacteria which are known to have beneficial health related properties, such as Odoribacteraceae,” Dr. Leta said.
This bacterium is “known to be reduced in people with Parkinson’s disease,” she explained, “and is involved in the production of short-chain fatty acids, which are known to have beneficial health-related properties.”
The secondary endpoint of the study included changes in motor and nonmotor symptoms, and the probiotic was associated with a significant improvement in the “time to on” with levodopa treatment, shortening this period from an average of 31.43 minutes at baseline to 23.95 minutes at the postintervention assessment (P < .027).
There was also a significant improvement in the Non-Motor Symptoms Scale (NMSS) score between baseline and the postintervention assessment in patients given the probiotic, from 70.71 to 61.34 (P = .005).
This, Dr. Leta observed, was “driven by improvements in the sleep, fatigue, and gastrointestinal domains.”
No such significant improvements were observed in the placebo arm.

Delaying palliative chemo may improve QoL without affecting survival for asymptomatic patients
TOPLINE:
METHODOLOGY:
- Traditionally, chemotherapy is started immediately when advanced cancer is diagnosed, but delaying chemotherapy until symptoms start could improve QoL.
- To find out, investigators performed a meta-analysis of five studies that explored the timing of palliative chemotherapy. The analysis included three randomized trials in advanced colorectal cancer (CRC), one in advanced ovarian cancer, and a review of patients with stage IV gastric cancer.
- Of the 919 patients, treatment was delayed for 467 patients (50.8%) until symptoms started in the colorectal trials. It was delayed until tumor recurrence in the ovarian cancer trial, and it was delayed until a month or more had passed in the gastric cancer study, regardless of symptoms.
- QoL was assessed largely by the EORTC-QLQ-C30 questionnaire. Median follow-up ranged from 11 to 60 months.
TAKEAWAY:
- The researchers found no significant differences in overall survival between patients for whom chemotherapy was delayed and those for whom chemotherapy began immediately (pooled hazard ratio [HR], 1.05; 95% confidence interval [CI], 0.90-1.22; P = .52).
- Median overall survival was 11.9 to 25.7 months with immediate treatment, vs. 9 to 27.1 months with delayed treatment.
- In the three studies that evaluated QoL, the findings suggested that QoL was largely better among patients whose treatment was delayed. In the CRC studies that assessed QoL, for instance, global health status in the delayed treatment group was higher than that in the immediate treatment group at almost all time points, but not significantly so.
- Rates of grade 3/4 toxicities, evaluated in two studies, did not differ significantly between the groups.
IN PRACTICE:
There is limited evidence on the optimal timing for starting chemotherapy for asymptomatic patients with advanced cancer. In these studies, delaying chemotherapy until symptoms occurred did not result in worse overall survival compared with immediate treatment and may have resulted in better QoL, the researchers concluded. They noted that for asymptomatic patients, delaying the start of systemic therapy should be discussed with the patient.
SOURCE:
The study, led by Simone Augustinus of the University of Amsterdam, was published online Aug. 17 in The Oncologist.
LIMITATIONS:
- Only three types of cancer were included in the analysis, and the findings may not be generalizable to other types of cancer.
- Some of the studies were older and employed out-of-date treatment regimens.
- QoL was only evaluated in three of five studies and could not be evaluated overall in the meta-analysis because of the different time points measured in each trial.
DISCLOSURES:
The study received no external funding. Two investigators have advisory, speaker, and/or research ties to Celgene, Novartis, AstraZeneca, and other companies.

FROM THE ONCOLOGIST
Hemophilia: Concizumab lessens bleeding, could expand treatment options
Concizumab (Novo Nordisk), a subcutaneous monoclonal antibody administered once daily, shows significant reductions in annualized bleeding rates in patients with hemophilia A or B with inhibitors, potentially representing the first subcutaneous treatment option for patients with hemophilia B with inhibitors.
“These results demonstrate the potential of concizumab as an efficacious treatment option for people living with hemophilia A or B with inhibitors – the latter a population with severely limited treatment options,” first author Tadashi Matsushita, MD, PhD, of the department of transfusion medicine, Nagoya (Japan) University Hospital, said in an interview regarding the study, published in the New England Journal of Medicine.
The results are from the prospective, multicenter, phase 3 explorer7 trial, involving 133 patients, including 80 with hemophilia A and 53 had hemophilia B, all with inhibitors, a complication of hemophilia therapy in which antibodies ‘inhibit’ clot formation and complicate standard treatment.
The patients, aged 12 or older and all receiving on-demand treatment with bypassing agents, were randomized to receive no prophylaxis for at least 24 weeks (n = 19) or concizumab prophylaxis for at least 32 weeks (n = 33), with the remaining patients nonrandomly assigned to two groups receiving concizumab prophylaxis for at least 24 weeks (n = 81).
For the primary endpoint of the estimated mean annualized bleeding rate, the rate in the no-prophylaxis group was 11.8 episodes versus just 1.7 episodes in the concizumab prophylaxis 32-week group (rate ratio, 0.14; P < .001).
The overall median annualized bleeding rate for patients in all three groups receiving concizumab was zero episodes.
Annualized rates of treated spontaneous, joint, and target joint bleeding episodes were also lower in the concizumab groups versus the no-prophylaxis group, with annualized rate ratios that were similar to the annualized rate ratio for the primary endpoint.
While similar annualized bleeding rates were observed in hemophilia subtypes, the study wasn’t powered to show superiority according the hemophilia A or B, the authors noted.
Plasma concentrations of concizumab remained stable over the course of the study.
There were no significant differences in terms of key secondary endpoints of change in bodily pain and physical functioning scores from the start of treatment to week 24.
Pause for safety
Treatment in the study was paused for 6 months from March 2020 to August 2020 following nonfatal thromboembolic events occurring in three patients receiving concizumab, including one in the explorer7 trial and two in the concurrent explorer8 trial, evaluating the drug in patients with hemophilia without inhibitors.
The authors wrote that the three patients had all received concomitant treatment for bleeding and had thrombotic risk factors including obesity and other comorbidities.
The trial resumed following mitigation measures that included revising the dosing regimen to include a 1–mg/kg concizumab loading dose, followed by a subcutaneous once-daily dose of 0.2 mg/kg concizumab. No further thromboembolic events were reported after the pause. Otherwise, adverse events were mainly low grade, with serious events being rare.
Option for hemophilia B important
Of the two disease types, hemophilia A is much more common, with an estimated prevalence in the United States of 12 cases per 100,000 males versus hemophilia B, which has a rate of only 3.7 cases per 100,000, according to the Centers for Disease Control and Prevention. Women make up only about 1% of cases with moderate to severe hemophilia.
A standard treatment of hemophilia A or B is prophylaxis with factor replacement therapies allow for improved clotting and reduced bleeding. However, one caveat is the need for intravenous injections, as often as once daily in some cases.
The development of inhibitors in response to replacement therapy may further necessitate the need for treatment with bypassing agents for breakthrough bleeding.
As an alternative, non–factor replacement therapies can promote coagulation, notably the factor VIII mimetic emicizumab, given by subcutaneous injection, and approved by the Food and Drug Administration in 2018 for patients with and without inhibitors.
Emicizumab is recommended by the World Federation on Hemophilia over bypassing agents as prophylaxis for patients with hemophilia A and persistent inhibitors.
Importantly, however, there are no effective prophylactic treatments or easily administered subcutaneous therapies available for hemophilia B with inhibitors, underscoring the potential importance of concizumab, which targets the tissue factor pathway inhibitor protein, linked to coagulation.
“Concizumab has the potential to become the first subcutaneous and first-in-class treatment for hemophilia B with inhibitors,” Dr. Matsushita said. “There are other therapies investigated for hemophilia B with and without inhibitors still in clinical development,” he noted.
FDA resubmission planned
In May, Novo Nordisk announced that the FDA had rejected its application for concizumab, requesting more information on the drug’s manufacturing process and its system for the monitoring and dosing of patients to ensure proper drug administration. In a statement, Novo Nordisk reported its plans to move ahead.
“Novo Nordisk has begun addressing the FDA’s feedback and is working closely with the FDA as plans for resubmission continue,” the company reported. “We are confident in the potential of concizumab to address a significant unmet need, particularly for people with hemophilia B with inhibitors who currently have limited prophylactic options and are committed to bringing this important treatment to people with hemophilia with inhibitors living in the U.S.A.”
Meanwhile in Canada, concizumab was approved in March 2023 for the treatment of adolescent and adult patients with hemophilia B with inhibitors and who require routine prophylaxis to prevent or reduce the frequency of bleeding episodes.
The authors wrote that concizumab continues to be investigated across all hemophilia subtypes, including in the explorer10 study, which is evaluating the drug in children living with hemophilia A or B, with and without inhibitors.
The study was supported by Novo Nordisk. Dr. Matsushita reported speaking for and participating on a scientific advisory board of Novo Nordisk.

The patients, aged 12 or older and all receiving on-demand treatment with bypassing agents, were randomized to receive no prophylaxis for at least 24 weeks (n = 19) or concizumab prophylaxis for at least 32 weeks (n = 33), with the remaining patients nonrandomly assigned to two groups receiving concizumab prophylaxis for at least 24 weeks (n = 81).
For the primary endpoint of the estimated mean annualized bleeding rate, the rate in the no-prophylaxis group was 11.8 episodes versus just 1.7 episodes in the concizumab prophylaxis 32-week group (rate ratio, 0.14; P < .001).
The overall median annualized bleeding rate for patients in all three groups receiving concizumab was zero episodes.
Annualized rates of treated spontaneous, joint, and target joint bleeding episodes were also lower in the concizumab groups versus the no-prophylaxis group, with annualized rate ratios that were similar to the annualized rate ratio for the primary endpoint.
While similar annualized bleeding rates were observed in hemophilia subtypes, the study wasn’t powered to show superiority according the hemophilia A or B, the authors noted.
Plasma concentrations of concizumab remained stable over the course of the study.
There were no significant differences in terms of key secondary endpoints of change in bodily pain and physical functioning scores from the start of treatment to week 24.
Pause for safety
Treatment in the study was paused for 6 months from March 2020 to August 2020 following nonfatal thromboembolic events occurring in three patients receiving concizumab, including one in the explorer7 trial and two in the concurrent explorer8 trial, evaluating the drug in patients with hemophilia without inhibitors.
The authors wrote that the three patients had all received concomitant treatment for bleeding and had thrombotic risk factors including obesity and other comorbidities.
The trial resumed following mitigation measures that included revising the dosing regimen to include a 1–mg/kg concizumab loading dose, followed by a subcutaneous once-daily dose of 0.2 mg/kg concizumab. No further thromboembolic events were reported after the pause. Otherwise, adverse events were mainly low grade, with serious events being rare.
Option for hemophilia B important
Of the two disease types, hemophilia A is much more common, with an estimated prevalence in the United States of 12 cases per 100,000 males versus hemophilia B, which has a rate of only 3.7 cases per 100,000, according to the Centers for Disease Control and Prevention. Women make up only about 1% of cases with moderate to severe hemophilia.
A standard treatment of hemophilia A or B is prophylaxis with factor replacement therapies allow for improved clotting and reduced bleeding. However, one caveat is the need for intravenous injections, as often as once daily in some cases.
The development of inhibitors in response to replacement therapy may further necessitate the need for treatment with bypassing agents for breakthrough bleeding.
As an alternative, non–factor replacement therapies can promote coagulation, notably the factor VIII mimetic emicizumab, given by subcutaneous injection, and approved by the Food and Drug Administration in 2018 for patients with and without inhibitors.
Emicizumab is recommended by the World Federation on Hemophilia over bypassing agents as prophylaxis for patients with hemophilia A and persistent inhibitors.
Importantly, however, there are no effective prophylactic treatments or easily administered subcutaneous therapies available for hemophilia B with inhibitors, underscoring the potential importance of concizumab, which targets the tissue factor pathway inhibitor protein, linked to coagulation.
“Concizumab has the potential to become the first subcutaneous and first-in-class treatment for hemophilia B with inhibitors,” Dr. Matsushita said. “There are other therapies investigated for hemophilia B with and without inhibitors still in clinical development,” he noted.
FDA resubmission planned
In May, Novo Nordisk announced that the FDA had rejected its application for concizumab, requesting more information on the drug’s manufacturing process and its system for the monitoring and dosing of patients to ensure proper drug administration. In a statement, Novo Nordisk reported its plans to move ahead.
“Novo Nordisk has begun addressing the FDA’s feedback and is working closely with the FDA as plans for resubmission continue,” the company reported. “We are confident in the potential of concizumab to address a significant unmet need, particularly for people with hemophilia B with inhibitors who currently have limited prophylactic options and are committed to bringing this important treatment to people with hemophilia with inhibitors living in the U.S.A.”
Meanwhile in Canada, concizumab was approved in March 2023 for the treatment of adolescent and adult patients with hemophilia B with inhibitors and who require routine prophylaxis to prevent or reduce the frequency of bleeding episodes.
The authors wrote that concizumab continues to be investigated across all hemophilia subtypes, including in the explorer10 study, which is evaluating the drug in children living with hemophilia A or B, with and without inhibitors.
The study was supported by Novo Nordisk. Dr. Matsushita reported speaking for and participating on a scientific advisory board of Novo Nordisk.

FDA approves canakinumab for gout flares
The U.S. Food and Drug Administration has approved canakinumab (Ilaris) for the treatment of gout flares in adults who cannot be treated with NSAIDs, colchicine, or repeated courses of corticosteroids. The drug is also indicated for people who could not tolerate or had an inadequate response to NSAIDs or colchicine.
The drug, a humanized anti–interleukin-1 beta monoclonal antibody, is the first and only biologic approved in the United States for the treatment of gout flares, according to Novartis. It is administered in a single, subcutaneous injection of 150 mg.
“At Novartis, we are committed to bringing medicines that address high unmet needs to patients. We are proud to receive approval on our eighth indication for Ilaris in the U.S. and provide the first biologic medicine option for people with gout flares to help treat this painful and debilitating condition,” the company said in a statement to this news organization.
Canakinumab was first approved in the United States in 2009 for the treatment of children and adults with cryopyrin-associated periodic syndrome (CAPS). Since then, it has been approved for the treatment of several other autoinflammatory diseases, including Still’s disease and recurrent fever syndromes.
In 2011, an FDA advisory panel voted against the approval of canakinumab to treat acute gout flares refractory to NSAIDs, colchicine, or repeated courses of corticosteroids, while in 2013, the European Medicine Agency approved the drug for this treatment indication.
Since that FDA advisory committee meeting and the FDA’s subsequent rejection letter, “[Novartis] has conducted additional studies in patients with gout flares and other related populations to further characterize the short- and long-term safety of canakinumab supporting the current application. To further support the benefit-risk [profile of the drug], the indication is for a more restricted population than initially proposed in 2011,” the FDA’s Center for Drug Evaluation and Research said in a statement to this news organization. “Given these considerations and the available safety information, the Agency determined that canakinumab, at the recommended dosage, has a favorable risk-benefit profile” in the specified patient population.

Dietary nitrates reduce contrast-induced nephropathy in ACS
AMSTERDAM –
In the NITRATE-CIN Study, non-ST segment elevation myocardial infarction acute coronary syndrome (ACS) patients at risk of renal injury from coronary angiography who received dietary inorganic nitrates had a 70% reduction in CIN compared with those given placebo.
The nitrate group also showed an impressive reduction in periprocedural myocardial infarction (MI) and improved renal function at 3 months, as well as a halving of major adverse cardiovascular events and major adverse kidney events at 1 year.
The trial was presented by Dan Jones, MD, Barts Health NHS Trust, London, at the annual congress of the European Society of Cardiology.
“Currently, aside from intravenous hydration, there is no proven treatment that reduces contrast-induced nephropathy. We feel that dietary inorganic nitrate shows huge promise in this study, and these findings could have important implications in reducing this serious complication of coronary angiography,” Dr. Jones concluded.
He explained that the product used was a formulation of dietary inorganic nitrates given as potassium nitrate capsules, which the study investigators produced specifically for this trial.
At this point, “the only way to get inorganic nitrate is in the diet – specifically by consuming beetroot juice or green leafy vegetables such as spinach and rocket. From a clinician perspective, while these results suggest this is an effective therapy and has great potential, it is not currently possible to prescribe the medication we used in our study, although we are working on producing a commercial product,” he said in an interview.
However, Dr. Jones noted that it is possible to buy beetroot shots, which contain 7 mmol of potassium nitrate in each shot, from health food shops and websites, and two such shots per day for 5 days would give a dose similar to that used in this study, starting the day before angiography.
“While we need a larger multicenter study to confirm these results, studies so far suggest no signal at all that there is any harm in this approach, and there could be a great deal of benefit in taking a couple of beetroot shots prior to and for a few days after an angiogram,” he said.
Dietary nitrates “make sense”
Designated discussant of the NITRATE-CIN trial at the ESC Hotline session, Roxanna Mehran, MD, Icahn School of Medicine at Mount Sinai, New York, said the study was well designed, and the “interesting and plausible” hypothesis to raise nitric oxide levels by dietary nitrates “makes sense.”
On the main findings of a major significant 50% reduction in acute kidney injury, Dr. Mehran said, “It is difficult to imagine such a reduction is possible.”
She pointed out that the large reduction in major adverse cardiac events and major adverse kidney events at 1 year also suggests that there is a sustained benefit in protecting the kidney.
“We’re all going to get on beet juice after this,” she quipped.
Still, Dr. Mehran questioned whether the results were “too good to be true,” adding that a larger trial actually powered for longer term outcome events is needed, as well as a better understanding of whether CIN has a causative role in mortality.
Responding to questions about whether such a large effect could actually be achieved with dietary nitrates, Dr. Jones said he thought there would definitely be some benefits, but maybe not quite as large as those seen in this study.
“From our pilot data we thought nitrate may be effective in preventing CIN,” he said in an interview. “We recruited a higher risk group than we thought, which is why the control event rates were higher than we expected, but the acute kidney injury reduction is roughly what we had estimated, and makes sense biologically.”
Dr. Jones acknowledged that the large reductions in long-term major adverse cardiovascular and kidney events were unexpected.
“The trial was not powered to see reductions in these outcomes, so we need to see if those event reductions can be replicated in larger multicenter trials,” he said. “But this was a double-blind placebo-controlled trial so in this trial the effects are real, and I think the effect size in this trial is too large for there not to be a beneficial effect.
“But I’m not so sure that we would see the same magnitude of effect when we have a larger study with tighter confidence intervals but perhaps a 20%-25% reduction in cardiovascular and kidney may be more realistic, which would still be amazing for such an easy and cost-effective intervention,” Dr. Jones added.
A larger trial is now being planned.
The researchers are also working on the development of a commercial form of dietary inorganic nitrate that would be needed for larger multicenter studies and would then be generally available. “We want this to be a low-cost product that would be available to all,” Dr. Jones said.
He noted that other studies have shown that dietary inorganic nitrates in the form of beetroot juice lower blood pressure; there are suggestions it may also lower cholesterol and prevent stent restenosis, and athletes sometimes take it to increase their aerobic capacity.
“There appears to be many benefits of dietary nitrates, and the one thing we can do at this time is to encourage people to increase their dietary nitrate consumption by eating large quantities of green leafy vegetables and beetroot,” Dr. Jones said.
Replacing lost nitric oxide
In his presentation, Dr. Jones noted that CIN is a serious complication after coronary angiography and is associated with longer hospital stays, worse long-term kidney function, and increased risk of MI and death.
The incidence varies depending on patient risk and definitions used, but it can affect up to 50% of high-risk ACS patients – older patients and/or those with heart failure, chronic kidney disease, or diabetes.
“We don’t really understand the mechanisms that cause CIN, but multiple proposed mechanisms exist, and we know from previous studies that a deficiency of nitric oxide is crucial to the development of CIN,” he explained. “We also know that [nitric oxide] is crucial for normal renal hemostasis. Therefore, a potential therapeutic target to prevent CIN would be to replace this lost nitric oxide.”
The inorganic nitrate evaluated in this trial is found in the diet, is produced endogenously, and is different from medicinally synthesized organic nitrates such as isosorbide mononitrate, he said.
“Isosorbide mononitrate/dinitrate tablets contain organic nitrates and while they are good for angina, we know that they do not have the same beneficial effects on the sustained generation of nitric oxide as inorganic nitrates,” Dr. Jones added.
NITRATE-CIN study
NITRATE-CIN was a double-blind, randomized, placebo-controlled trial conducted at Queen Mary University of London and St. Bartholomew’s Hospital in London, which tested the effectiveness of inorganic nitrate in preventing contrast-induced nephropathy in 640 patients with non-ST elevation ACS referred for invasive coronary angiography.
To be eligible for the trial, patients had to be at risk of contrast-induced nephropathy with an estimated glomerular filtration rate (eGFR) less than 60 mL/min per 1.73 m2 or have two of the following significant risk factors: diabetes, liver failure, over 70 years of age, exposure to contrast within 7 days, heart failure, or on concomitant renally acting drugs.
Patients were randomly assigned to a formulation of potassium nitrate (12 mmol/744 mg nitrate) per day given as capsules for a 5-day course with the first dose administered prior to angiography or to a control group that received potassium chloride with a matched potassium concentration.
The patient population had a mean age of 71 years, 73% were male, 75% were White, 46% had diabetes, and 56% had chronic kidney disease. There was a 13% loss to follow-up, which was attributed to the COVID pandemic.
The amount of contrast administration was 180 mL in the placebo and 170 mL in the nitrate arm, with 50% of patients undergoing some sort of revascularization.
The primary endpoint was the incidence of CIN as defined by KDIGO criteria – a series of stages of acute kidney injury defined by changes in serum creatinine within 72 hours and up to 1 week.
Results showed that this primary CIN endpoint was reduced significantly from 30% in the placebo arm to 9.1% in the nitrate group, a 70% relative risk reduction (P < .0001). The majority (90%) of this CIN was stage 1, but 10% was stage 2.
Consistent results were seen when an alternative definition of CIN (Mehran) was used, although the rates in both arms were lower than when the KDIGO definition was used.
The benefit was seen across prespecified subgroups including diabetes status, troponin positivity, and Mehran risk. But the benefit seemed to be attenuated in patients on preexisting organic nitrate therapy, although the numbers in these groups were too small to draw definitive conclusions.
As would be expected, there were significant elevations in both systemic nitrate and nitrite levels both up to 72 hours after the procedure, which was consistent with the 5-day course. This was associated with reductions in systolic and diastolic blood pressure, but not associated with any adverse events, Dr. Jones reported.
Rates of procedural MI, a prespecified secondary endpoint, were reduced from 12.5% to 4.1% in those on inorganic nitrates (P = .003).
Looking at longer term outcomes, kidney function was improved at 3 months as measured by change in eGFR, which showed a 10% relative improvement of 5.2 mL/min per 1.73 m2 (10%) in the nitrate group vs. the placebo group. Serum creatinine levels were also significantly increased in the nitrate group.
At 12 months, there was a significant 50% relative reduction in major adverse cardiovascular events – including all-cause mortality, recurrent MI, and recurrent revascularization – which were reduced from 18.1% in the placebo group to 9.1% in the nitrate group, with a reduction in all three of the constituent components of the composite endpoint including all-cause mortality.
Major adverse kidney events (all-cause mortality, renal replacement therapy, or persistent renal dysfunction) were also reduced at 12 months from 28.4% in the placebo group to 10.7% in the nitrate group (P < .0001), a 60% relative reduction. This was driven by lower rates of all-cause mortality and persistent renal dysfunction.
While Dr. Jones said these results on major cardiovascular and kidney outcomes should be viewed as hypothesis-generating at the present time, he said there were biological mechanisms that could explain these benefits.
“We saw a reduction in procedural MI, and we know there is a lot of similar biology in preventing procedural MI and subsequent cardiac events in the acute phase. This, in combination with the large reduction in acute kidney injury, could explain why there’s improved outcomes out to 12 months.”
In her comments, Dr. Mehran congratulated the investigators on having conducted the first study to have shown benefit in the prevention of contrast-associated acute kidney injury as well as major adverse cardiovascular and kidney events associated with the condition.
She used the term “contrast-associated acute kidney injury” rather than “contrast-induced nephropathy” because, she said, it has not been proven that the acute kidney injury seen after angiography is actually caused by the contrast and “so many other things are occurring during procedures when these patients are presenting with different syndromes.”
Dr. Mehran pointed out some weaknesses in the NITRATE-CIN study including the single-center design, the large volume of contrast administered, 13% of patients missing the primary endpoint blood draw, and an imbalance in relevant baseline characteristics despite randomization.
The NITRATE-CIN study was funded by Heart Research UK. Dr. Jones has disclosed no relevant financial relationships.

At this point, “the only way to get inorganic nitrate is in the diet – specifically by consuming beetroot juice or green leafy vegetables such as spinach and rocket. From a clinician perspective, while these results suggest this is an effective therapy and has great potential, it is not currently possible to prescribe the medication we used in our study, although we are working on producing a commercial product,” he said in an interview.
However, Dr. Jones noted that it is possible to buy beetroot shots, which contain 7 mmol of potassium nitrate in each shot, from health food shops and websites, and two such shots per day for 5 days would give a dose similar to that used in this study, starting the day before angiography.
“While we need a larger multicenter study to confirm these results, studies so far suggest no signal at all that there is any harm in this approach, and there could be a great deal of benefit in taking a couple of beetroot shots prior to and for a few days after an angiogram,” he said.
Dietary nitrates “make sense”
Designated discussant of the NITRATE-CIN trial at the ESC Hotline session, Roxanna Mehran, MD, Icahn School of Medicine at Mount Sinai, New York, said the study was well designed, and the “interesting and plausible” hypothesis to raise nitric oxide levels by dietary nitrates “makes sense.”
On the main findings of a major significant 50% reduction in acute kidney injury, Dr. Mehran said, “It is difficult to imagine such a reduction is possible.”
She pointed out that the large reduction in major adverse cardiac events and major adverse kidney events at 1 year also suggests that there is a sustained benefit in protecting the kidney.
“We’re all going to get on beet juice after this,” she quipped.
Still, Dr. Mehran questioned whether the results were “too good to be true,” adding that a larger trial actually powered for longer term outcome events is needed, as well as a better understanding of whether CIN has a causative role in mortality.
Responding to questions about whether such a large effect could actually be achieved with dietary nitrates, Dr. Jones said he thought there would definitely be some benefits, but maybe not quite as large as those seen in this study.
“From our pilot data we thought nitrate may be effective in preventing CIN,” he said in an interview. “We recruited a higher risk group than we thought, which is why the control event rates were higher than we expected, but the acute kidney injury reduction is roughly what we had estimated, and makes sense biologically.”
Dr. Jones acknowledged that the large reductions in long-term major adverse cardiovascular and kidney events were unexpected.
“The trial was not powered to see reductions in these outcomes, so we need to see if those event reductions can be replicated in larger multicenter trials,” he said. “But this was a double-blind placebo-controlled trial so in this trial the effects are real, and I think the effect size in this trial is too large for there not to be a beneficial effect.
“But I’m not so sure that we would see the same magnitude of effect when we have a larger study with tighter confidence intervals but perhaps a 20%-25% reduction in cardiovascular and kidney may be more realistic, which would still be amazing for such an easy and cost-effective intervention,” Dr. Jones added.
A larger trial is now being planned.
The researchers are also working on the development of a commercial form of dietary inorganic nitrate that would be needed for larger multicenter studies and would then be generally available. “We want this to be a low-cost product that would be available to all,” Dr. Jones said.
He noted that other studies have shown that dietary inorganic nitrates in the form of beetroot juice lower blood pressure; there are suggestions it may also lower cholesterol and prevent stent restenosis, and athletes sometimes take it to increase their aerobic capacity.
“There appears to be many benefits of dietary nitrates, and the one thing we can do at this time is to encourage people to increase their dietary nitrate consumption by eating large quantities of green leafy vegetables and beetroot,” Dr. Jones said.
Replacing lost nitric oxide
In his presentation, Dr. Jones noted that CIN is a serious complication after coronary angiography and is associated with longer hospital stays, worse long-term kidney function, and increased risk of MI and death.
The incidence varies depending on patient risk and definitions used, but it can affect up to 50% of high-risk ACS patients – older patients and/or those with heart failure, chronic kidney disease, or diabetes.
“We don’t really understand the mechanisms that cause CIN, but multiple proposed mechanisms exist, and we know from previous studies that a deficiency of nitric oxide is crucial to the development of CIN,” he explained. “We also know that [nitric oxide] is crucial for normal renal hemostasis. Therefore, a potential therapeutic target to prevent CIN would be to replace this lost nitric oxide.”
The inorganic nitrate evaluated in this trial is found in the diet, is produced endogenously, and is different from medicinally synthesized organic nitrates such as isosorbide mononitrate, he said.
“Isosorbide mononitrate/dinitrate tablets contain organic nitrates and while they are good for angina, we know that they do not have the same beneficial effects on the sustained generation of nitric oxide as inorganic nitrates,” Dr. Jones added.
NITRATE-CIN study
NITRATE-CIN was a double-blind, randomized, placebo-controlled trial conducted at Queen Mary University of London and St. Bartholomew’s Hospital in London, which tested the effectiveness of inorganic nitrate in preventing contrast-induced nephropathy in 640 patients with non-ST elevation ACS referred for invasive coronary angiography.
To be eligible for the trial, patients had to be at risk of contrast-induced nephropathy with an estimated glomerular filtration rate (eGFR) less than 60 mL/min per 1.73 m2 or have two of the following significant risk factors: diabetes, liver failure, over 70 years of age, exposure to contrast within 7 days, heart failure, or on concomitant renally acting drugs.
Patients were randomly assigned to a formulation of potassium nitrate (12 mmol/744 mg nitrate) per day given as capsules for a 5-day course with the first dose administered prior to angiography or to a control group that received potassium chloride with a matched potassium concentration.
The patient population had a mean age of 71 years, 73% were male, 75% were White, 46% had diabetes, and 56% had chronic kidney disease. There was a 13% loss to follow-up, which was attributed to the COVID pandemic.
The amount of contrast administration was 180 mL in the placebo and 170 mL in the nitrate arm, with 50% of patients undergoing some sort of revascularization.
The primary endpoint was the incidence of CIN as defined by KDIGO criteria – a series of stages of acute kidney injury defined by changes in serum creatinine within 72 hours and up to 1 week.
Results showed that this primary CIN endpoint was reduced significantly from 30% in the placebo arm to 9.1% in the nitrate group, a 70% relative risk reduction (P < .0001). The majority (90%) of this CIN was stage 1, but 10% was stage 2.
Consistent results were seen when an alternative definition of CIN (Mehran) was used, although the rates in both arms were lower than when the KDIGO definition was used.
The benefit was seen across prespecified subgroups including diabetes status, troponin positivity, and Mehran risk. But the benefit seemed to be attenuated in patients on preexisting organic nitrate therapy, although the numbers in these groups were too small to draw definitive conclusions.
As would be expected, there were significant elevations in both systemic nitrate and nitrite levels both up to 72 hours after the procedure, which was consistent with the 5-day course. This was associated with reductions in systolic and diastolic blood pressure, but not associated with any adverse events, Dr. Jones reported.
Rates of procedural MI, a prespecified secondary endpoint, were reduced from 12.5% to 4.1% in those on inorganic nitrates (P = .003).
Looking at longer term outcomes, kidney function was improved at 3 months as measured by change in eGFR, which showed a 10% relative improvement of 5.2 mL/min per 1.73 m2 (10%) in the nitrate group vs. the placebo group. Serum creatinine levels were also significantly increased in the nitrate group.
At 12 months, there was a significant 50% relative reduction in major adverse cardiovascular events – including all-cause mortality, recurrent MI, and recurrent revascularization – which were reduced from 18.1% in the placebo group to 9.1% in the nitrate group, with a reduction in all three of the constituent components of the composite endpoint including all-cause mortality.
Major adverse kidney events (all-cause mortality, renal replacement therapy, or persistent renal dysfunction) were also reduced at 12 months from 28.4% in the placebo group to 10.7% in the nitrate group (P < .0001), a 60% relative reduction. This was driven by lower rates of all-cause mortality and persistent renal dysfunction.
While Dr. Jones said these results on major cardiovascular and kidney outcomes should be viewed as hypothesis-generating at the present time, he said there were biological mechanisms that could explain these benefits.
“We saw a reduction in procedural MI, and we know there is a lot of similar biology in preventing procedural MI and subsequent cardiac events in the acute phase. This, in combination with the large reduction in acute kidney injury, could explain why there’s improved outcomes out to 12 months.”
In her comments, Dr. Mehran congratulated the investigators on having conducted the first study to have shown benefit in the prevention of contrast-associated acute kidney injury as well as major adverse cardiovascular and kidney events associated with the condition.
She used the term “contrast-associated acute kidney injury” rather than “contrast-induced nephropathy” because, she said, it has not been proven that the acute kidney injury seen after angiography is actually caused by the contrast and “so many other things are occurring during procedures when these patients are presenting with different syndromes.”
Dr. Mehran pointed out some weaknesses in the NITRATE-CIN study including the single-center design, the large volume of contrast administered, 13% of patients missing the primary endpoint blood draw, and an imbalance in relevant baseline characteristics despite randomization.
The NITRATE-CIN study was funded by Heart Research UK. Dr. Jones has disclosed no relevant financial relationships.

AT THE ESC CONGRESS 2023
IV iron shows only modest benefit in HF: HEART-FID
AMSTERDAM – , but the study failed to meet the specified more rigorous definition of significance (P = .01) on the primary hierarchical composite of death, hospitalizations for heart failure, or 6-minute walk distance.
The trial, which investigated intravenous ferric carboxymaltose treatment vs. placebo, also showed no statistical difference in the main secondary endpoint: time to cardiovascular death or first heart failure hospitalization.
It was hoped that HEART-FID, the largest study to date to look at intravenous iron supplementation in heart failure, would confirm benefits suggested in previous smaller studies, but its modest results seem to have, if anything, caused more uncertainly on whether supplementing iron is actually worthwhile.
The HEART-FID trial was presented at the annual congress of the European Society of Cardiology and simultaneously published online in the New England Journal of Medicine.
Another presentation at the ESC Congress reported a pooled meta-analysis of all the intravenous iron supplementation studies, including HEART-FID. This showed a significant reduction in one coprimary endpoint (cardiovascular hospitalization/CV death) but not in the other (heart failure hospitalization/CV death), which is the more traditional and well-recognized endpoint in heart failure trials.
The meta-analysis was also published online in the European Heart Journal.
HEART-FID lead investigator, Robert J. Mentz, MD, Duke University, Durham, N.C., said the totality of the evidence showed clinical benefits of intravenous iron supplementation with intravenous ferric carboxymaltose.
“I worry that people will focus on a P value rather than the actual clinical benefits seen across all the studies,” Dr. Mentz said in an interview. “Technically, this study was neutral in respect to the primary endpoint, but when we look at all the evidence with respect to ferric carboxymaltose, including this new pooled analysis, this does support clinical benefits.”
Comoderator of the ESC Hotline session at which the trial was presented, John McMurray, MD, University of Glasgow (Scotland), thought the trial had “muddied the waters a bit” on the issue of iron supplementation in heart failure.
“I would say we are in a less clear position on iron supplementation now than we were a few months ago. Those clinicians who have believed that checking iron levels and supplementing iron in those who are low is the right thing to do may now be wondering about that,” he told this news organization.
Dr. McMurray noted that initial impressions of the data from both HEART-FID and the meta-analysis suggested some benefit of intravenous iron on CV death/heart failure hospitalization in the first year, but on longer term follow-up, that benefit was less evident.
“We need to look further into why there is that discrepancy,” he said. “This could be a statistical phenomenon or could be something to do with the frequency of redosing over the longer term.”
He explained that several previous studies of intravenous iron supplementation in heart failure have reported apparent convincing benefits on quality of life and functional capacity, but there has been some uncertainty on this because of the difficulty in producing a placebo for intravenous iron.
“So, it would have been great to have some additional confirmation of these benefits and on harder endpoints,” he said, “but even in HEART-FID, there was only a small nonsignificant benefit in walking distance.”
HEART-FID
The HEART-FID trial randomly assigned 3,065 ambulatory patients with heart failure, a left ventricular ejection fraction of 40% or less, and iron deficiency to intravenous ferric carboxymaltose or placebo, given every 6 months as needed on the basis of iron indexes and hemoglobin levels, in addition to standard therapy for heart failure.
The primary outcome was a hierarchical composite of death within 12 months after randomization, hospitalizations for heart failure within 12 months after randomization, or change from baseline to 6 months in the 6-minute walk distance. The significance level was set at .01.
Results showed that death by month 12 occurred in 8.6% of the ferric carboxymaltose group and 10.3% of the placebo group; a total of 297 and 332 hospitalizations for heart failure, respectively, occurred by month 12; and the mean change from baseline to 6 months in the 6-minute walk distance was 8 meters in the ferric carboxymaltose group and 4 meters with placebo. The P value for the primary composite was .02.
The trial also used another method (unmatched win ratio) to analyze the hierarchical composite outcome in the ferric carboxymaltose group as compared with the placebo group that gave a result of 1.10 (99% confidence interval, 0.99-1.23).
During the follow-up period, CV death or hospitalization for heart failure (the main secondary outcome) occurred in 31.0% of the ferric carboxymaltose group and in 32.2% of the placebo group (hazard ratio, 0.93; 96% CI, 0.81-1.06).
Repeated dosing of ferric carboxymaltose appeared to be safe, with an acceptable adverse-event profile in most patients. The number of patients with serious adverse events occurring during the treatment period was similar in the two groups (27.0% in the ferric carboxymaltose group and 26.2% in the placebo group).
‘It’s hard to argue that we are not disappointed’
Designated discussant of the HEART-FID study at the ESC HOTLINE session, Scott Solomon, MD, Brigham and Women’s Hospital, Boston, described HEART-FID as “an extremely important and well-conducted trial.”
He noted that iron deficiency is extremely common in patients with heart failure, affecting at least about a third of patients, and is associated with reduced New York Heart Association class and reduced survival. Previous smaller studies have suggested benefit but have narrowly missed their primary endpoints. HEART-FID was a larger and sufficiently well-powered trial to test the hypothesis that iron supplementation can improve harder clinical endpoints.
Dr. Solomon said that the primary endpoint could be difficult to interpret, with a hierarchical composite, and a win ratio. “But I think it’s fair to say that the results are modest at best,” he added.
“When we look at the traditional cardiovascular death/heart failure hospitalization endpoint, one of the hard endpoints that we care about most in heart failure, it’s hard to argue that we are not disappointed,” he commented.
Referring to the P value of .01 threshold set for significance, which is based on new U.S. Food and Drug Administration regulatory standards, Dr. Solomon noted, “If they had used a standard P = .05 threshold, then they would be able to claim that this trial had met its primary endpoint. But, nevertheless, whatever threshold for significance we look at, the benefit was clearly modest.”
“As with all trials that show modest results, it will be useful to look at subgroups that are most likely to respond to the greatest extent to this therapy, and I look forward to learning more on this from further analyses,” Dr. Solomon concluded.
In an accompanying editorial in the New England Journal of Medicine, Pieter Martens, MD, and Wilfried Mullens, MD, PhD, Ziekenhuis Oost-Limburg, Genk, Belgium, and Hasselt (Belgium) University, point out that analyses from previous trials have suggested that intravenous iron did not have a treatment effect in patients with a transferrin saturation of more than 20%.
They note that, in the ferric carboxymaltose group in the HEART-FID trial, the mean transferrin saturation was 23.9% at baseline, higher than in previous studies.
Future analyses should assess the importance of the transferrin saturation value at baseline, which “could help redefine the definition of iron deficiency in patients with heart failure and, we hope, help clinicians determine which patients might benefit from intravenous iron supplementation,” they write.
Meta-analysis of trials
The meta-analysis of intravenous iron supplementation trials in heart failure was presented by Piotr Ponikowski, MD, Medical University Wroclaw (Poland).
The analysis pooled individual patient data from three double-blind, placebo-controlled trials – CONFIRM-HF 2, AFFIRM-AHF 3, and HEART-FID – giving a total of 4,475 patients, with 2,241 receiving ferric carboxymaltose and 2,234 receiving placebo.
The two prespecified composite primary endpoints were CV hospitalizations/CV death and heart failure hospitalizations/CV death.
These showed similar 13%-14% relative risk reductions with ferric carboxymaltose, but only the former was statistically significant.
Similar results were seen when a fourth trial – IRONMAN (an open-label trial) – was included. In this case, the heart failure hospitalization/CV death endpoint was also nonsignificantly reduced with ferric carboxymaltose (rate ratio, 0.82; 95% CI, 0.58-1.07).
Subgroup analysis suggested that patients with higher transferrin saturation levels appeared to have a lack of treatment effect, whereas those with lower transferrin saturation (< 15%) showed significant treatment benefits.
A higher 6-month cumulative dose of ferric carboxymaltose – likely the result of redosing – may be associated with a slightly greater treatment effect after 6 months, Dr. Ponikowski reported.
He concluded: “These data support the use of intravenous ferric carboxymaltose to treat iron deficiency among patients with heart failure with reduced/mildly reduced LVEF [left ventricular ejection fraction] to reduce the risk of future hospitalization.”
“Our findings support additional research to challenge the current definition of iron deficiency in heart failure as an indication for IV iron therapy and to identify eligibility criteria for optimal redosing strategy,” Dr. Ponikowski added.
Discussant of the meta-analysis presentation at the ESC Hotline session, Pardeep Jhund, MD, University of Glasgow, suggested that the endpoint of most interest would be heart failure hospitalization/CV death in the analysis that included the IRONMAN trial, “which unfortunately did not meet statistical significance.”
In answer to the question “Where does this leave clinicians when treating patients?”Dr. Jhund said, “After yet another meta-analysis, I think the role of IV iron in reducing morbidity and mortality outcomes in heart failure remains questionable.”
“While the absence of evidence is not evidence of absence, the wide confidence intervals of the treatment effect on heart failure hospitalization/CV death leaves a lot of room for doubt about the efficacy of IV iron for reducing HF hospitalizations,” he concluded.
The HEART-FID trial was funded by American Regent, a Daiichi Sankyo Group company. Dr. Mentz reports receiving research support from American Regent and honoraria from American Regent, Vifor, and Pharmacosmos. Dr. Ponikowski reports consultancy fees/honoraria from Vifor Pharma, Boehringer Ingelheim, AstraZeneca, Servier, Novartis, Bayer, MSD, Pfizer, Moderna, Sanofi, and Radcliffe Group.

The P value for the primary composite was .02.
The trial also used another method (unmatched win ratio) to analyze the hierarchical composite outcome in the ferric carboxymaltose group as compared with the placebo group that gave a result of 1.10 (99% confidence interval, 0.99-1.23).
During the follow-up period, CV death or hospitalization for heart failure (the main secondary outcome) occurred in 31.0% of the ferric carboxymaltose group and in 32.2% of the placebo group (hazard ratio, 0.93; 96% CI, 0.81-1.06).
Repeated dosing of ferric carboxymaltose appeared to be safe, with an acceptable adverse-event profile in most patients. The number of patients with serious adverse events occurring during the treatment period was similar in the two groups (27.0% in the ferric carboxymaltose group and 26.2% in the placebo group).
‘It’s hard to argue that we are not disappointed’
Designated discussant of the HEART-FID study at the ESC HOTLINE session, Scott Solomon, MD, Brigham and Women’s Hospital, Boston, described HEART-FID as “an extremely important and well-conducted trial.”
He noted that iron deficiency is extremely common in patients with heart failure, affecting at least about a third of patients, and is associated with reduced New York Heart Association class and reduced survival. Previous smaller studies have suggested benefit but have narrowly missed their primary endpoints. HEART-FID was a larger and sufficiently well-powered trial to test the hypothesis that iron supplementation can improve harder clinical endpoints.
Dr. Solomon said that the primary endpoint could be difficult to interpret, with a hierarchical composite, and a win ratio. “But I think it’s fair to say that the results are modest at best,” he added.
“When we look at the traditional cardiovascular death/heart failure hospitalization endpoint, one of the hard endpoints that we care about most in heart failure, it’s hard to argue that we are not disappointed,” he commented.
Referring to the P value of .01 threshold set for significance, which is based on new U.S. Food and Drug Administration regulatory standards, Dr. Solomon noted, “If they had used a standard P = .05 threshold, then they would be able to claim that this trial had met its primary endpoint. But, nevertheless, whatever threshold for significance we look at, the benefit was clearly modest.”
“As with all trials that show modest results, it will be useful to look at subgroups that are most likely to respond to the greatest extent to this therapy, and I look forward to learning more on this from further analyses,” Dr. Solomon concluded.
In an accompanying editorial in the New England Journal of Medicine, Pieter Martens, MD, and Wilfried Mullens, MD, PhD, Ziekenhuis Oost-Limburg, Genk, Belgium, and Hasselt (Belgium) University, point out that analyses from previous trials have suggested that intravenous iron did not have a treatment effect in patients with a transferrin saturation of more than 20%.
They note that, in the ferric carboxymaltose group in the HEART-FID trial, the mean transferrin saturation was 23.9% at baseline, higher than in previous studies.
Future analyses should assess the importance of the transferrin saturation value at baseline, which “could help redefine the definition of iron deficiency in patients with heart failure and, we hope, help clinicians determine which patients might benefit from intravenous iron supplementation,” they write.
Meta-analysis of trials
The meta-analysis of intravenous iron supplementation trials in heart failure was presented by Piotr Ponikowski, MD, Medical University Wroclaw (Poland).
The analysis pooled individual patient data from three double-blind, placebo-controlled trials – CONFIRM-HF 2, AFFIRM-AHF 3, and HEART-FID – giving a total of 4,475 patients, with 2,241 receiving ferric carboxymaltose and 2,234 receiving placebo.
The two prespecified composite primary endpoints were CV hospitalizations/CV death and heart failure hospitalizations/CV death.
These showed similar 13%-14% relative risk reductions with ferric carboxymaltose, but only the former was statistically significant.
Similar results were seen when a fourth trial – IRONMAN (an open-label trial) – was included. In this case, the heart failure hospitalization/CV death endpoint was also nonsignificantly reduced with ferric carboxymaltose (rate ratio, 0.82; 95% CI, 0.58-1.07).
Subgroup analysis suggested that patients with higher transferrin saturation levels appeared to have a lack of treatment effect, whereas those with lower transferrin saturation (< 15%) showed significant treatment benefits.
A higher 6-month cumulative dose of ferric carboxymaltose – likely the result of redosing – may be associated with a slightly greater treatment effect after 6 months, Dr. Ponikowski reported.
He concluded: “These data support the use of intravenous ferric carboxymaltose to treat iron deficiency among patients with heart failure with reduced/mildly reduced LVEF [left ventricular ejection fraction] to reduce the risk of future hospitalization.”
“Our findings support additional research to challenge the current definition of iron deficiency in heart failure as an indication for IV iron therapy and to identify eligibility criteria for optimal redosing strategy,” Dr. Ponikowski added.
Discussant of the meta-analysis presentation at the ESC Hotline session, Pardeep Jhund, MD, University of Glasgow, suggested that the endpoint of most interest would be heart failure hospitalization/CV death in the analysis that included the IRONMAN trial, “which unfortunately did not meet statistical significance.”
In answer to the question “Where does this leave clinicians when treating patients?”Dr. Jhund said, “After yet another meta-analysis, I think the role of IV iron in reducing morbidity and mortality outcomes in heart failure remains questionable.”
“While the absence of evidence is not evidence of absence, the wide confidence intervals of the treatment effect on heart failure hospitalization/CV death leaves a lot of room for doubt about the efficacy of IV iron for reducing HF hospitalizations,” he concluded.

Traditional Chinese medicine improves outcomes in HFrEF
When added to guideline-directed therapies for heart failure with reduced ejection fraction (HFrEF), a traditional Chinese medicine called qiliqiangxin reduced the composite endpoint of cardiovascular death and heart failure hospitalization by more than 20%, results of a large placebo-controlled trial show.
reported Xinli Li, MD, PhD, First Affiliated Hospital, Nanjing Medical University, China.
Qiliqiangxin, a commonly used therapy in China for cardiovascular disease, is not a single chemical entity but a treatment composed of 11 plant-based substances that together are associated with diuretic effects, vasodilation, and “cardiotonic” activity, Dr. Li said. He also cited studies showing an upregulation effect on peroxisome proliferator-activated receptor gamma coactivator 1-beta (PGC1-beta).
The results were presented at the annual congress of the European Society of Cardiology.
Hard endpoints pursued in rigorous design
There have been numerous studies of qiliqiangxin for cardiovascular diseases, including a double-blind study that associated this agent with a greater than 30% reduction in the surrogate endpoint of N-terminal pro–B-type natriuretic peptide (NT-proBNP).
In the newly completed multicenter trial, called QUEST, the goal was to determine whether this therapy could reduce hard endpoints relative to placebo in a rigorously conducted trial enrolling patients receiving an optimized triple-therapy heart failure regimen.
Few patients in the study received a sodium glucose cotransporter-2 (SGLT-2 inhibitor), which was not a standard at the time the study was designed but is now part of the quadruple guideline-directed medical therapy in most European and North American guidelines.
In this trial, 3,119 patients were randomly assigned at 133 centers in China to take four capsules of qiliqiangxin or placebo three times per day. At a median follow-up of 18.3 months, outcomes were evaluable in nearly all 1,561 patients randomly assigned to the experimental therapy and 1,555 patients randomly assigned to placebo.
The key inclusion criteria were a left ventricular ejection fraction of 40% or less and a serum NT-proBNP level of at least 450 pg/mL. Patients in New York Heart Association class IV heart failure were excluded.
At enrollment, more than 80% of patients in both arms were receiving a renin-angiotensin system (RAS) inhibitor (angiotensin-converting enzyme inhibitor, angiotensin receptor blocker, or angiotensin receptor neprilysin inhibitor), more than 80% were receiving a mineralocorticoid receptor antagonist, and more than 85% were receiving a beta-blocker.
Death and hospitalization reduced 22%
By hazard ratio, the primary composite endpoint of CV death and heart failure hospitalization was reduced by 22% relative to placebo (HR, 0.78; P < .001). When evaluated separately, the relative reductions in these respective endpoints were 17% (HR, 0.83; P = .045) and 24% (HR, 0.76; P = .002).
The risk reduction was robust (HR, 0.76; P < .001) in patients with an ischemic cause but nonsignificant in those without (HR, 0.92; P = .575). A significant benefit was sustained in patients receiving an angiotensin receptor neprilysin inhibitor (HR, 0.84; P = .041), as well as those who did not receive this class of drug (HR, 0.77; P = .012).
However, the benefit of qiliqiangxin among patients receiving all components of guideline-directed triple therapy (RAS inhibitor, beta-blocker, and mineralocorticoid antagonist) was only a trend (HR, 0.86; P = .079).
All-cause mortality, a secondary endpoint, was lower among patients randomly assigned to qiliqiangxin than to those assigned to placebo, but this difference fell just short of statistical significance (14.21% vs. 16.85%; P = .058).
Qiliqiangxin was well tolerated. The proportion of patients with a serious adverse event was numerically lower with qiliqiangxin than with placebo (17.43% vs. 19.74%), whereas discontinuations associated with an adverse event were numerically higher in the qiliqiangxin group (1.03% vs. 0.58%), albeit still very low in both study arms.
Overlap of drug benefits suspected
Given the safety of this drug and its highly significant reduction in a composite endpoint used in other major HFrEF trials, the ESC-invited discussant, Carolyn S.P. Lam, MBBS, PhD, National Heart Centre, Singapore, called the outcome “remarkable” and a validation for “the millions of people” who are already taking qiliqiangxin in China and other Asian countries.
Using the DAPA-HF trial as a point of reference, Dr. Lam noted that relative reduction in the composite endpoint of cardiovascular death for the SGLT-2 inhibitor dapagliflozin relative to placebo on top of triple guideline-directed medical therapy was lower (17% vs. 24%), but there were significant reductions in each of the components, as well as a nonsignificant signal of a mortality benefit.
However, Dr. Lam pointed out that there does seem to be more of an overlap for the benefits of qiliqiangxin than dapagliflozin relative to other components of triple therapy based on the lower rate of benefit when patients were optimized on triple therapy.
“The subgroup analysis [of this study] is very important,” Dr. Lam said. Qiliqiangxin may be best in patients who cannot take one or more of the components of triple therapy, she suggested, even though she called for further studies to test this theory. She also cautioned that the pill burden of four capsules taken three times per day might be onerous for some patients.
Of the many questions still to be answered, Dr. Lam noted that the low rate of enrollment for patients (< 10%) taking SGLT-2 inhibitors makes the contribution of qiliqiangxin unclear among those receiving the current standard of quadruple guideline-directed medical therapy.
She also suggested that it will be important to dissect the relative contribution of the different active ingredients of qiliqiangxin.
“This is not a purified compound that we are used to in Western medicine,” Dr. Lam said. While she praised the study as “scientifically rigorous” and indicated that the results support a clinical benefit from qiliqiangxin, she thinks an exploration of the mechanism or mechanisms of benefit is a next step in understanding where this therapy fits in HFrEF management.
