The “twincretin” era for treating patients with type 2 diabetes has begun, with the Food and Drug Administration’s approval of tirzepatide for this indication on May 13, making it the first approved agent that works as a dual agonist for the two principal human incretins.

Tirzepatide represents “an important advance in the treatment of type 2 diabetes,” the FDA’s Patrick Archdeacon, MD, associate director of the division of diabetes, lipid disorders, and obesity, said in a statement released by the agency.

That advance is based on tirzepatide’s engineering, which gives it agonist properties for both the glucagonlike peptide–1 (GLP-1) receptor, as well as the glucose-dependent insulinotropic polypeptide (GIP). Several agents are already approved for U.S. use from the class with single-agonist activity on the GLP-1 receptor, including semaglutide (Ozempic for treating patients with type 2 diabetes; Wegovy for weight loss).

The FDA’s approved label includes all three dosages of tirzepatide that underwent testing in the pivotal trials: 5 mg, 10 mg, and 15 mg, each delivered by subcutaneous injection once a week. Also approved was the 2.5-mg/week dose used when starting a patient on the agent. Gradual up-titration appears to minimize possible gastrointestinal adverse effects during initial tirzepatide use.

Tirzepatide, which will be marketed by Lilly as Mounjaro, will hit the U.S. market with much anticipation, based on results from five pivotal trials, all reported during the past year or so, that established the drug’s unprecedented efficacy for reducing hemoglobin A1c levels as well as triggering significant weight loss in most patients with a generally benign safety profile.
 

‘Impressive’ effects

The effects from tirzepatide on A1c and weight seen in these studies was “impressive, and will likely drive use of this agent,” commented Carol H. Wysham, MD, an endocrinologist at the MultiCare Rockwood Clinic in Spokane, Wash.

Tirzepatide received good notices in several editorials that accompanied the published reports of the pivotal trials. The first of these, a commentary from two U.K.-based endocrinologists, said that “tirzepatide appears to represent an advancement over current GLP-1 analogues, providing enhanced glycemic and weight benefits without an added penalty in terms of gastrointestinal adverse effects.”

The pivotal trials included head-to-head comparisons between tirzepatide and a 1.0-mg/week dose of semaglutide, as well as comparisons with each of two long-acting insulin analogs, insulin glargine (Lantus) and insulin degludec (Tresiba).

“These are the most important comparators,” Dr. Wysham said.

“Tirzepatide was appropriately compared with the best-in-class and most effective glucose-lowering agents currently available,” said Ildiko Lingvay, MD, an endocrinologist and professor at the University of Texas Southwestern Medical Center in Dallas.

“Given its outstanding efficacy at both lowering glucose and weight, I expect tirzepatide to have quick uptake among patients with diabetes,” Dr. Lingvay said. “The only limiting factor will be cost,” she added in an interview, highlighting the major stumbling block that could limit tirzepatide’s uptake.

“As with any new medication, access will be the biggest barrier to uptake,” agreed Alice Y.Y. Cheng, MD, an endocrinologist at the University of Toronto.
 

Lingering uncertainties

The timing of the comparison with semaglutide leaves some unanswered questions. The SURPASS-2 trial compared the three primary tirzepatide regimens (5 mg, 10 mg, and 15 mg/week) with a 1.0-mg/week dose of semaglutide, which was at the time the only approved dosage of semaglutide for patients with type 2 diabetes. Since then, a 2.0-mg/week dosage of semaglutide (Ozempic) received U.S. approval for treating patients with type 2 diabetes, and a 2.4-mg/week dosage (Wegovy) received an FDA nod for treating people with obesity.

The lack of head-to-head data for tirzepatide against the 2.0-mg/week dose of semaglutide “leaves a clinical gap,” said Dr. Cheng. Tirzepatide “represents an advance over semaglutide at the 1-mg/week dose, but we do not know for sure compared to the higher dose.”

Another important limitation for tirzepatide right now is that the agent’s obligatory cardiovascular outcome trial, SURPASS CVOT, with about 12,500 enrolled patients, will not have findings out until about 2025, leaving uncertainty until then about tirzepatide’s cardiovascular effects.

“We are missing the cardiovascular outcome data – very important data will come” from that trial, noted Dr. Wysham. “There will be some reluctance to use the agent in high-risk patients until we see the results.”

Given tirzepatide’s proven efficacy so far, the missing cardiovascular results “are not a limitation for most patients, but for patients with preexisting cardiovascular disease I will continue to use agents with proven benefits until the SURPASS CVOT results come out,” Dr. Lingvay said.

And then there is the cost issue, something that Lilly had not yet publicly addressed at the time that the FDA announced its decision.

An analysis of cost effectiveness published by the U.S. Institute for Clinical and Economic Review in February 2022 concluded that tirzepatide had a better impact on patient quality of life, compared with 1.0 mg/week semaglutide for treating patients with type 2 diabetes, which gave it a modest pricing cushion, compared with semaglutide of about $5,500 per quality-adjusted life-year gained. But the researchers who prepared the report admitted that tirzepatide’s cost-effectiveness was hard to estimate without knowing the drug’s actual price.  

Dr. Wysham has financial ties to AstraZeneca, Abbott, Boehringer Ingelheim, Intercept, Janssen, Mylan, Novo Nordisk, and Sanofi. Dr. Lingvay has dies to Lilly, Novo Nordisk, Sanofi, Boehringer Ingelheim, Merck, Pfizer, and Mylan, Intarcia, MannKind, Valeritas, and several other drug and device makers.

WASHINGTON – Patients with type 2 diabetes and established atherosclerotic cardiovascular disease treated with both an sodium-glucose transporter 2 inhibitor and a glucagonlike peptide–1 receptor agonist had a significant 80% cut in their rate of all-cause death during 1-year follow-up, compared with matched patients treated with an agent from either class alone in an observational, retrospective study of more than 15,000 people in the U.S. Veterans Affairs health system.

For the study’s primary endpoint, the combined rate of all-cause death, nonfatal MI, or nonfatal stroke, combined treatment with both an agent from the sodium-glucose transporter 2 (SGLT2) inhibitor class and from the glucagonlike peptide–1 receptor agonist (GLP-1 RA) class linked with a significant, roughly 50% cut in events during 1-year follow-up, compared with patients treated with an agent from just one of these two classes, Persio D. Lopez, MD, reported at the annual scientific sessions of the American College of Cardiology.

Mitchel L. Zoler/MDedge News

This improvement in the combined endpoint outcome resulted entirely from reduced all-cause mortality. Dual treatment showed no significant association with the incidence of nonfatal MIs or strokes, compared with monotherapy, with rates that were nearly identical regardless of whether patients took one of the agents or both, said Dr. Lopez, a cardiologist at Mount Sinai Morningside and the James J. Peters VA Medical Center, both in New York.
 

Combining classes for hard-to-control diabetes

“We’re not sure what drives combined use” of agents from both drug classes in these types of patients, admitted Dr. Lopez during his talk. “Our hypothesis is that dual treatment is used in patients with harder-to-control diabetes.”

Salim S. Virani, MD, PhD, who practices in the VA system but was not involved with the study, agreed that this is the likely explanation for most instances of high-risk VA patients with diabetes who receive agents from both classes.

Mitchel L. Zoler/MDedge News

“I have a few patients” on both classes, usually “patients with higher starting A1c levels who need greater glycemic control,” said Dr. Virani, professor of medicine at Baylor College of Medicine and a cardiologist at the Michael E. DeBakey VA Medical Center, both in Houston.

U.S. use of either drug class, let alone both, in patients with type 2 diabetes is still struggling to gain traction in U.S. practice and remains limited to a minority of these patients, a prescribing pattern reflected in recent VA data. Analysis of more than half a million patients in the VA system with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD) who received treatment at any of 130 VA medical centers throughout 2020 showed that 11% had received an SGLT2 inhibitor, and 8% a GLP-1 RA.

The most frequently used antidiabetes drug classes in these patients were insulin in 36%, biguanides in 47%, and sulfonylureas in 22%.

These data also showed a striking level of variability among the 130 VA centers, with some of the sites prescribing either an SGLT2 inhibitor or a GLP-1 RA to as few as about 3% each of these patients, while other centers had a roughly 10-fold higher prescription rate for each of about 25%-30% of their patients with type 2 diabetes and ASCVD.

Despite the overall modest level of use of both classes in these types of patients as recently as 2020, no barriers exist at the VA to prescribing an agent from one or both classes “if you provide a good reason” for a patient to receive the drugs, Dr. Virani said in an interview. He also predicted that use of both classes in these patients, including combination treatment, will likely soon expand.
 

‘A lot of interest’ in combining an SGLT2 inhibitor and a GLP-1 RA

“There will be a lot of interest in combing the two classes. It makes intuitive sense [to treat with both classes] because most patients with diabetes need more than one drug” for glycemic control, he noted. “Why not use two classes that each reduce a patient’s risk” for adverse outcomes involving ASCVD, heart failure, and renal dysfunction, added Dr. Virani.

The study run by Dr. Lopez and his associates used data collected in the National VA Database and included 121,156 patients with both type 2 diabetes and established ASCVD. Using propensity-score matching the researchers compiled three subgroups that each included 5,277 matched patients. One subgroup had patients prescribed an SGLT2 inhibitor, a second subgroup included patients on a GLP-1 RA, and a third subgroup had patients on agents from both classes. Patient matching relied on age, sex, left ventricular ejection fraction, hemoglobin A1c level, systolic blood pressure, and the presence of coronary artery disease or peripheral artery disease.

Patients included in the analysis averaged about 67 years of age; 97% were men, their average body mass index was about 34 kg/m², their average A1c was about 7.9%, their average estimated glomerular filtration rate was about 55-66 mL/min per 1.73 m², and their average left ventricular ejection fraction was about 55%. The database provided a median follow-up of 902 days (about 2.5 years). The prespecified primary endpoint focused on events that occurred during the first year of follow-up, but the investigators also ran a 3-year follow-up analysis on a post hoc basis.

The most common SGLT2 inhibitor received by these patients was empagliflozin (Jardiance), used on virtually everyone who received an agent from this class. In contrast, the GLP-1 RA drugs that patients received split more widely. The most prescribed agent was liraglutide (Victoza), followed by semaglutide (Ozempic), and dulaglutide (Trulicity), with fewer than 5% receiving exenatide (Bydureon, Byetta).

Regarding other treatments, about 97% of all patients received a statin, about 94% were on a renin-angiotensin system inhibitor, about 90% were on metformin, and roughly 75% were on insulin, aspirin, and a beta-blocker, with smaller numbers on other types of agents.

For the study’s primary endpoint, the 1-year incidence of combined ASCVD events including all-cause death, patients on agents from both classes had a significant 46% reduced rate compared with those on an SGLT2 inhibitor only, and a significant 49% reduced rate, compared with those on a GLP-1 RA only. These between-group separations broadened slightly during 3-year follow-up. Dr. Lopez did not report results of a direct comparison between patients on just an SGLT2 inhibitor and those on just a GLP-1 RA.

For the endpoint of all-cause death, those on combined treatment had a 1-year rate that was 83% below the rate among patients on only an SGLT2 inhibitor, and 81% below the rate among patients who received a GLP-1 RA but not the other class.

Dr. Lopez cautioned that selection bias could have influenced the outcomes of patients who received both classes rather than one or the other, and he also highlighted that the analysis relied on administrative data rather than information gleaned from more detailed medical records or prospectively collected findings and was limited by only including a very small number of women.

“Our results need to be validated in prospective studies,” he declared.

Dr. Lopez and Dr. Virani had no commercial disclosures.

Lopez, MD, reported at the annual scientific sessions of the American College of Cardiology.

This improvement in the combined endpoint outcome resulted entirely from reduced all-cause mortality. Dual treatment showed no significant association with the incidence of nonfatal MIs or strokes, compared with monotherapy, with rates that were nearly identical regardless of whether patients took one of the agents or both, said Dr. Lopez, a cardiologist at Mount Sinai Morningside and the James J. Peters VA Medical Center, both in New York.
 

Combining classes for hard-to-control diabetes

“We’re not sure what drives combined use” of agents from both drug classes in these types of patients, admitted Dr. Lopez during his talk. “Our hypothesis is that dual treatment is used in patients with harder-to-control diabetes.”

Salim S. Virani, MD, PhD, who practices in the VA system but was not involved with the study, agreed that this is the likely explanation for most instances of high-risk VA patients with diabetes who receive agents from both classes.

“I have a few patients” on both classes, usually “patients with higher starting A1c levels who need greater glycemic control,” said Dr. Virani, professor of medicine at Baylor College of Medicine and a cardiologist at the Michael E. DeBakey VA Medical Center, both in Houston.

U.S. use of either drug class, let alone both, in patients with type 2 diabetes is still struggling to gain traction in U.S. practice and remains limited to a minority of these patients, a prescribing pattern reflected in recent VA data. Analysis of more than half a million patients in the VA system with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD) who received treatment at any of 130 VA medical centers throughout 2020 showed that 11% had received an SGLT2 inhibitor, and 8% a GLP-1 RA.

The most frequently used antidiabetes drug classes in these patients were insulin in 36%, biguanides in 47%, and sulfonylureas in 22%.

These data also showed a striking level of variability among the 130 VA centers, with some of the sites prescribing either an SGLT2 inhibitor or a GLP-1 RA to as few as about 3% each of these patients, while other centers had a roughly 10-fold higher prescription rate for each of about 25%-30% of their patients with type 2 diabetes and ASCVD.

Despite the overall modest level of use of both classes in these types of patients as recently as 2020, no barriers exist at the VA to prescribing an agent from one or both classes “if you provide a good reason” for a patient to receive the drugs, Dr. Virani said in an interview. He also predicted that use of both classes in these patients, including combination treatment, will likely soon expand.
 

‘A lot of interest’ in combining an SGLT2 inhibitor and a GLP-1 RA

“There will be a lot of interest in combing the two classes. It makes intuitive sense [to treat with both classes] because most patients with diabetes need more than one drug” for glycemic control, he noted. “Why not use two classes that each reduce a patient’s risk” for adverse outcomes involving ASCVD, heart failure, and renal dysfunction, added Dr. Virani.

The study run by Dr. Lopez and his associates used data collected in the National VA Database and included 121,156 patients with both type 2 diabetes and established ASCVD. Using propensity-score matching the researchers compiled three subgroups that each included 5,277 matched patients. One subgroup had patients prescribed an SGLT2 inhibitor, a second subgroup included patients on a GLP-1 RA, and a third subgroup had patients on agents from both classes. Patient matching relied on age, sex, left ventricular ejection fraction, hemoglobin A1c level, systolic blood pressure, and the presence of coronary artery disease or peripheral artery disease.

Patients included in the analysis averaged about 67 years of age; 97% were men, their average body mass index was about 34 kg/m², their average A1c was about 7.9%, their average estimated glomerular filtration rate was about 55-66 mL/min per 1.73 m², and their average left ventricular ejection fraction was about 55%. The database provided a median follow-up of 902 days (about 2.5 years). The prespecified primary endpoint focused on events that occurred during the first year of follow-up, but the investigators also ran a 3-year follow-up analysis on a post hoc basis.

The most common SGLT2 inhibitor received by these patients was empagliflozin (Jardiance), used on virtually everyone who received an agent from this class. In contrast, the GLP-1 RA drugs that patients received split more widely. The most prescribed agent was liraglutide (Victoza), followed by semaglutide (Ozempic), and dulaglutide (Trulicity), with fewer than 5% receiving exenatide (Bydureon, Byetta).

Regarding other treatments, about 97% of all patients received a statin, about 94% were on a renin-angiotensin system inhibitor, about 90% were on metformin, and roughly 75% were on insulin, aspirin, and a beta-blocker, with smaller numbers on other types of agents.

For the study’s primary endpoint, the 1-year incidence of combined ASCVD events including all-cause death, patients on agents from both classes had a significant 46% reduced rate compared with those on an SGLT2 inhibitor only, and a significant 49% reduced rate, compared with those on a GLP-1 RA only. These between-group separations broadened slightly during 3-year follow-up. Dr. Lopez did not report results of a direct comparison between patients on just an SGLT2 inhibitor and those on just a GLP-1 RA.

For the endpoint of all-cause death, those on combined treatment had a 1-year rate that was 83% below the rate among patients on only an SGLT2 inhibitor, and 81% below the rate among patients who received a GLP-1 RA but not the other class.

Dr. Lopez cautioned that selection bias could have influenced the outcomes of patients who received both classes rather than one or the other, and he also highlighted that the analysis relied on administrative data rather than information gleaned from more detailed medical records or prospectively collected findings and was limited by only including a very small number of women.

“Our results need to be validated in prospective studies,” he declared.

Dr. Lopez and Dr. Virani had no commercial disclosures.

WASHINGTON – Treatment of patients acutely hospitalized for heart failure with the SGLT2 inhibitor empagliflozin led to a rapid incremental increase in patient well-being, compared with control patients who received placebo, that appeared after 2 weeks on treatment in a secondary analysis from 530 randomized patients in the EMPULSE trial.

To Mikhail N. Kosiborod, MD, a coinvestigator for EMPULSE who presented new analysis at the annual scientific sessions of the American College of Cardiology, the message from the quick response of acutely hospitalized patients to empagliflozin was clear: “Use these medications, SGLT2 [sodium-glucose cotransporter 2] inhibitors, as early as possible. We’ve seen with other medications that if they are not prescribed during hospitalization it’s unlikely to happen post discharge,” said Dr. Kosiborod, a cardiologist and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo.

“To our knowledge, the very early improvement in the Kansas City Cardiomyopathy Questionnaire [KCCQ] score – a well-known predictor of cardiovascular death and heart failure readmissions – that we observed with empagliflozin at 15 days is the first such observation, and if corroborated by future studies would suggest that initiation of SGLT2 inhibitors during hospitalization for acute heart failure may be a tool for improving the quality of hospital-to-home transitions,” wrote Dr. Kosiborod and his associates in the published version of their report that appeared concurrently with his report at the meeting.

“These data really support initiation [of empagliflozin or another SGLT2 inhibitor] in hospital, presuming that the patient has no contraindications,” commented Deepak L. Bhatt, MD, professor of medicine at Harvard Medical School in Boston and designated discussant for the report.

“The fact that the benefit kicks in so early is really important, because there is a bit of a penalty to wait” to start treatment with an agent from the SGLT2-inhibitor class, added Dr. Bhatt, who is also executive director of interventional cardiovascular programs at Brigham and Women’s Health, in Boston.

In hospital creates a teachable moment

Starting treatment when a patient is hospitalized is also important as “a teachable moment,” added Dr. Bhatt in an interview. “A physician can say to a patient ‘take this drug, and it will prevent you from returning to the hospital,’ at a time when it’s more likely to be impactful, compared with when a patient is out of the hospital and feeling okay and adherence will likely be much lower.”

Mitchel L. Zoler/MDedge News

The results Dr. Kosiborod reported on quality-of-life parameters measured with the KCCQ expanded on what he and his coinvestigators first reported in 2021 with the primary results from EMPULSE, which enrolled 530 patients at 118 centers in 15 countries during June 2020–February 2021. The trial randomized patients hospitalized for acute heart failure after a brief period of stabilization regardless of their left ventricular ejection fraction or presence of diabetes to receive a single, daily dose of 10 mg of empagliflozin (Jardiance) or placebo starting a median of 3 days after admission. Enrolled patients averaged about 71 years of age, about two-thirds were men, 45% had diabetes, 32% had left ventricular ejection fraction greater than 40%, and about two-thirds had decompensated chronic heart failure, while a third had acute de novo heart failure.

The primary outcome for EMPULSE was a combined endpoint of “total clinical endpoints” that included all-cause mortality, heart failure events (heart failure hospitalizations, urgent heart failure visits, and unplanned outpatient heart failure visits) or at least a 5-point change from baseline in the KCCQ score. Using a “win ratio” method for analyzing the composite endpoint, the primary analysis showed that treatment with empagliflozin for 90 days boosted the win ratio by a significant 36% relative to placebo (Nature Med. 2022 Mar;28[3]: 568-74).
 

Benefit independent of baseline symptomatic impairment

Among the new secondary analyses that Dr. Kosiborod reported was a post-hoc calculation that divided the study cohort into tertiles of baseline KCCQ score. The results showed that the degree of improvement for the primary, 90-day outcome of “total clinical benefit” compared with placebo was consistent across all three KCCQ-score tertiles, showing that empagliflozin’s benefit was “independent of symptomatic impairment at baseline,” he said.

The degree of improvement was also similar across all the tested domains of the KCCQ, including the overall summary, clinical summary, the physical limitations, and quality-of-life scores. Average improvement in KCCQ total symptom score 15 days after treatment onset was 5.35 points, compared with control patients. On an individual-patient basis, a change in KCCQ score of 5 points or more was previously shown to represent a clinically meaningful change.

“Treatment of patients with heart failure is geared to making patients live longer and stay out of the hospital. Enabling patients to feel better is an equally important goal of management, but not all treatments for heart failure can do that. These data from EMPULSE show that, in addition to other clinical benefits, patients also feel better on an SGLT2 inhibitor after just 2 weeks,” Dr. Kosiborod said in an interview.

EMPULSE builds on SOLOIST-WHF

EMPULSE is the second trial to show that an SGLT2 inhibitor can safely and effectively treat patients hospitalized for acute heart failure. Previously, results from the SOLOIST-WHF pivotal trial, which enrolled 1,222 patients with type 2 diabetes recently hospitalized for worsening heart failure, showed that treatment with an investigational, combined SGLT2 and SGLT1 inhibitor, sotagliflozin, resulted in a significant, 33% relative reduction in the primary outcome compared with placebo after a median 9 months of treatment.

“It’s reassuring to see two different drugs and research groups get essentially the same result, showing that starting an SGLT2 inhibitor is safe and effective in selected patients with no contraindications,” said Dr. Bhatt, who was lead investigator for SOLOIST-WHF.

The accumulating evidence for the safety and value of starting an SGLT2 inhibitor when patients are hospitalized for acute heart failure is making this approach increasingly routine for patients who present with heart failure with reduced ejection fraction at Saint Luke’s-Mid America Heart Institute, said Dr. Kosiborod, who is also a professor of medicine at the University of Missouri, Kansas City.

“I think we’ll also gradually start using [an SGLT2 inhibitor] in patients hospitalized with heart failure with preserved ejection fraction [HFpEF],” he added, based on the findings from SOLOIST-WHF and EMPULSE, and also recent evidence showing safety and efficacy of empagliflozin in patients with chronic HFpEF in the EMPEROR-Preserved trial, and for dapagliflozin (Farxiga) in the PRESERVED-HF trial.

Empagliflozin recently received from the U.S. Food and Drug Administration an expanded label indication for treating patients with heart failure with no specification for a level of left ventricular ejection fraction. An outcome trial of dapagliflozin in more than 6,000 patients with HFpEF, DELIVER, is currently ongoing but is expected to report results soon.

“The evidence is already compelling that the benefits outweigh the risk. Results from both SOLOIST-WHF and EMPULSE show that there are no significant safety concerns” when these agents are used in patients with acute heart failure,” Dr. Kosiborod declared.

EMPULSE was sponsored by Boehringer Ingelheim and Eli Lilly, the companies that jointly market empagliflozin (Jardiance). SOLOIST-WHF was sponsored by Sanofi and Lexicon, the companies that have been developing sotagliflozin. Dr. Kosiborod has been a consultant to and received research funding from Boehringer Ingelheim and Eli Lilly, and he has been a consultant or adviser to or led trials on behalf of numerous other companies. Dr. Bhatt has been an adviser to Boehringer Ingelheim and numerous other companies, and he has received research funding from Sanofi, Lexicon, Boehringer Ingelheim, Eli Lilly, and numerous other companies.

WASHINGTON – Patients with heart failure who received an annual influenza vaccine for 3 years running had significantly fewer all-cause hospitalizations and significantly fewer cases of pneumonia during that time, compared with placebo-treated patients with heart failure, in a prospective, randomized, global trial with 5,129 participants.

Although the results failed to show a significant reduction in all-cause deaths linked to influenza vaccination, compared with controls during the entire 3 years of the study, the results did show a significant 21% relative mortality-risk reduction by vaccination during periods of peak influenza circulation, and a significant 23% reduction in cardiovascular deaths, compared with controls during peak seasons.

“This is the first randomized, controlled trial of influenza vaccine in patients with heart failure, and we showed that vaccination reduces deaths” during peak influenza seasons, Mark Loeb, MD, said during a press briefing at the annual scientific sessions of the American College of Cardiology. The results send “an important global message that patients with heart failure should receive the influenza vaccine,” said Dr. Loeb, a professor at McMaster University, Hamilton, Ont., who specializes in clinical epidemiology and infectious diseases.

Dr. Loeb admitted that he and his associates erred when they picked the time window to assess the two primary endpoints for the trial: the combined rate of cardiovascular death, nonfatal MI, and nonfatal stroke, and this combined endpoint plus hospitalizations for heart failure.

The time window they selected was the entirety of all 3 years following three annual immunizations. That was a mistake.
 

No flu vaccine benefit outside flu season

“We know that the influenza vaccine will not have any effect outside of when influenza is circulating. In retrospect, we should have done that,” Dr. Loeb bemoaned during his talk. He chalked up the bad choice to concern over collecting enough endpoints to see a significant between-group difference when the researchers designed the study.

For the entire 3 years of follow-up, influenza vaccination was tied to a nonsignificant 7% relative risk reduction for the first primary endpoint, and a nonsignificant 9% relative risk reduction for the second primary endpoint, he reported.

But Dr. Loeb lobbied for the relevance of several significant secondary endpoints that collectively showed a compelling pattern of benefit during his talk. These included, for the full 3-years of follow-up, important, significant reductions relative to placebo of 16% for first all-cause hospitalizations (P = .01), and a 42% relative risk reduction in first cases of pneumonia (P = .0006).

Then there were the benefits that appeared during influenza season. In that analysis, first events for the first primary endpoint fell after vaccination by a significant 18% relative to placebo. The in-season analysis also showed the significant cuts in both all-cause and cardiovascular deaths.

Despite the neutral primary endpoints, “if you look at these data as a whole I think they speak to the importance of vaccinating patients with heart failure against influenza,” Dr. Loeb maintained.



‘Totality of evidence supports vaccination’

“I agree that the totality of evidence supports influenza vaccination,” commented Mark H. Drazner, MD, professor and clinical chief of cardiology at the University of Texas Southwestern Medical Center, Dallas, who was designated discussant for the report.

“The message should be to offer influenza vaccine to patients with heart failure,” Dr. Drazner said in an interview. “Previous data on influenza vaccine in patients with heart failure were largely observational. This was a randomized, prospective, placebo-controlled trial. That’s a step forward. Proving efficacy in a randomized trial is important.”

Dr Drazner added that his institution already promotes a “strong mandate” to vaccinate patients with heart failure against influenza.

“The influenza vaccine is a very effective and cost-efficient public health measure. Preventing hospitalizations of patients with heart failure has so many benefits,” commented Craig Beavers, PharmD, vice president of professional services at Baptist Health in Paducah, Ky., and a discussant during the press briefing.

The Influenza Vaccine To Prevent Adverse Vascular Events (IVVE) trial enrolled people with heart failure in New York Heart Association functional class II, III, or IV from any of 10 low- and middle-income countries including China, India, the Philippines, and multiple countries from Africa and the Middle East. They averaged 57 years of age, and slightly more than half were women.

IVVE was sponsored by McMaster University; the only commercial support that IVVE received was a free supply of influenza vaccine from Sanofi Pasteur. Dr. Loeb, Dr. Drazner, and Dr. Beavers had no disclosures.

WASHINGTON – Patients with heart failure who received an annual influenza vaccine for 3 years running had significantly fewer all-cause hospitalizations and significantly fewer cases of pneumonia during that time, compared with placebo-treated patients with heart failure, in a prospective, randomized, global trial with 5,129 participants.

Although the results failed to show a significant reduction in all-cause deaths linked to influenza vaccination, compared with controls during the entire 3 years of the study, the results did show a significant 21% relative mortality-risk reduction by vaccination during periods of peak influenza circulation, and a significant 23% reduction in cardiovascular deaths, compared with controls during peak seasons.

“This is the first randomized, controlled trial of influenza vaccine in patients with heart failure, and we showed that vaccination reduces deaths” during peak influenza seasons, Mark Loeb, MD, said during a press briefing at the annual scientific sessions of the American College of Cardiology. The results send “an important global message that patients with heart failure should receive the influenza vaccine,” said Dr. Loeb, a professor at McMaster University, Hamilton, Ont., who specializes in clinical epidemiology and infectious diseases.

Dr. Loeb admitted that he and his associates erred when they picked the time window to assess the two primary endpoints for the trial: the combined rate of cardiovascular death, nonfatal MI, and nonfatal stroke, and this combined endpoint plus hospitalizations for heart failure.

The time window they selected was the entirety of all 3 years following three annual immunizations. That was a mistake.
 

No flu vaccine benefit outside flu season

“We know that the influenza vaccine will not have any effect outside of when influenza is circulating. In retrospect, we should have done that,” Dr. Loeb bemoaned during his talk. He chalked up the bad choice to concern over collecting enough endpoints to see a significant between-group difference when the researchers designed the study.

For the entire 3 years of follow-up, influenza vaccination was tied to a nonsignificant 7% relative risk reduction for the first primary endpoint, and a nonsignificant 9% relative risk reduction for the second primary endpoint, he reported.

But Dr. Loeb lobbied for the relevance of several significant secondary endpoints that collectively showed a compelling pattern of benefit during his talk. These included, for the full 3-years of follow-up, important, significant reductions relative to placebo of 16% for first all-cause hospitalizations (P = .01), and a 42% relative risk reduction in first cases of pneumonia (P = .0006).

Then there were the benefits that appeared during influenza season. In that analysis, first events for the first primary endpoint fell after vaccination by a significant 18% relative to placebo. The in-season analysis also showed the significant cuts in both all-cause and cardiovascular deaths.

Despite the neutral primary endpoints, “if you look at these data as a whole I think they speak to the importance of vaccinating patients with heart failure against influenza,” Dr. Loeb maintained.

WASHINGTON – Treatment of patients with symptomatic obstructive hypertrophic cardiomyopathy who remained on treatment with the investigational agent mavacamten for a median of 62 weeks continued to show the same level of safe response to the drug as seen after the first 30 weeks on treatment in the pivotal trial for this agent.

The new findings from longer-term treatment bode well for mavacamten. That’s because if the drug is used in routine practice to avoid the need for surgery or an invasive intervention to reduce blockage of a patient’s left ventricular outflow tract, the duration of mavacamten treatment will likely need to continue for many years and even for decades, said Florian Rader, MD, who presented the results at the annual scientific sessions of the American College of Cardiology.

“In practice, mavacamten will probably be used for many, many years, especially as it replaces septal-reduction therapy, so we need long-term data,” noted Dr. Rader during a press briefing on his report. “I’m very happy with the long-term data” in the follow-up study.

The Food and Drug Administration is currently considering whether to approve mavacamten for routine marketing to treat patients with symptomatic obstructive hypertrophic cardiomyopathy (oHCM), with a decision expected by the end of April 2022.

The study Dr. Rader reported followed 231 patients with symptomatic oHCM who had completed the 30-week pivotal trial of mavacamten, EXPLORER-HCM, and opted to continue on open-label extended treatment with mavacamten, either continuing the treatment they started during the trial or crossing over to receive mavacamten after receiving placebo during the trial.

The major findings from EXPLORER-LTE (long-term extension) were that continued treatment for a median of about 62 weeks maintained the safety and efficacy findings seen at the end of the blinded, randomized, initial 30-week phase, said Dr. Rader, codirector of the Clinic for Hypertrophic Cardiomyopathy and Aortopathies at Cedars-Sinai Medical Center in Los Angeles.

‘Almost revolutionary’

Mavacamten represents “an almost revolutionary change” for treating oHCM, commented Maya E. Guglin, MD, professor of clinical medicine and an advanced heart failure physician at Indiana University, Indianapolis. “Until now, there was no good medical treatment for symptomatic oHCM. This will change the landscape, and without question it will change guidelines for treating oHCM,” said Dr. Guglin during the press briefing.

“All of us who care for patients with oHCM have looked forward to having a disease-specific therapy. It is encouraging to see that the safety and efficacy remained high with long-term follow-up,” commented Kyle W. Klarich, MD, a professor and cardiologist who specializes in treating patients with HCM at the Mayo Clinic in Rochester, Minn.

Mavacamten is a direct myosin inhibitor that reduces the excess number of myosin-actin cross bridges that form in patients with oHCM, and thereby directly targets the pathophysiology that underlies the disorder, explained Dr. Rader.

The patients on mavacamten included in the long-term extension reported by Dr. Rader averaged 60 years of age, and 61% were men. They averaged a 35.6–mm Hg drop in their resting left ventricular outflow tract (LVOT) gradient after 48 weeks on treatment, and a 32.8–mm Hg reduction after 84 weeks. When the investigators measured their LVOT gradient during a valsalva maneuver, their reductions from baseline averaged 45.3 mm Hg after 48 weeks and 46.4 mm Hg after 84 weeks.

Resting left ventricular ejection fraction also fell, by an average of 7.0 percentage points from baseline after 48 weeks, and by an average of 9.0 percentage points after 84 weeks. After 48 weeks on treatment, 68% of patients had at least a one-class improvement from baseline in their New York Heart Association functional class.

The safety results showed that most treatment-related adverse events were mild or moderate, and about 2% of patients had a serious drug-related adverse event. Ten of the 231 patients discontinued mavacamten because of a treated-related adverse event.

EXPLORER-HCM and EXPLORER-LTE were sponsored by MyoKardia, the company that is developing mavacamten and which is now owned by Bristol-Myers Squibb. Dr. Rader has been a consultant to MyoKardia as well as to Medtronic and ReCor. Dr. Guglin and Dr. Klarich had no disclosures.

WASHINGTON – Results from new analyses further fleshed out the potent effect by the investigational SGLT1&2 inhibitor sotagliflozin on major cardiovascular adverse events in patients with type 2 diabetes, chronic kidney disease, and at high risk for cardiovascular disease in the SCORED trial that randomized more than 10,000 patients.

In prespecified, secondary analyses of the SCORED results, treatment with sotagliflozin during a median of 16 months was linked to a significant 21% risk reduction relative to placebo for the combined incidence of total major adverse cardiovascular events (MACE), which included cardiovascular death, first and recurrent episodes of nonfatal MI, and nonfatal stroke among the 5,144 randomized patients who entered the trial with a history of cardiovascular disease (CVD), Deepak L. Bhatt, MD, said at the annual scientific sessions of the American College of Cardiology.

Mitchel L. Zoler/MDedge News

Among the 5,440 patients in the study who did not have a history of CVD (although they did have at least one major risk factor or at least two minor risk factors), treatment with sotagliflozin was linked to a significant 26% relative risk reduction in total MACE events.

Part of these overall MACE benefits resulted from similar improvements from sotagliflozin treatment on the individual outcomes of total nonfatal MI and total nonfatal strokes. Treatment with sotagliflozin cut these MIs by a significant 31% in patients with a history of CVD relative to patients who received placebo, and by a relative 34% in those without a CVD event in their history, a difference compared with placebo that fell short of significance, said Dr. Bhatt, professor of medicine at Harvard Medical School and executive director of interventional cardiovascular programs at Brigham and Women’s Health, both in Boston.

Treatment with sotagliflozin also cut total nonfatal strokes by 31% relative to placebo in patients with a history of CVD, and by a relative 38% in those without a CVD history. Both differences fell short of significance.
 

An early MACE benefit and a stroke benefit

“This stroke benefit has not been clearly seen” with any agent from the closely related sodium-glucose cotransport-2 (SGLT2) inhibitor class, and “the MACE benefit appeared very early,” within 3 months from the start of sotagliflozin treatment, “which may be because of the SGLT1 inhibition,” Dr. Bhatt said during his report.

The SGLT1 receptor is the primary mechanism cells in the gut use to absorb glucose and galactose in the human gastrointestinal tract, Dr. Bhatt explained, while the SGLT2 receptor appears on kidney cells and is the major player in the reabsorption of filtered glucose. The SGLT2 inhibitor class includes the agents canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance), while sotagliflozin inhibits both SGLT1 and SGLT2.

Main results from SCORED appeared in a report first released in late 2020, and showed that for the study’s primary endpoint treatment with sotagliflozin linked with a significant 26% relative risk reduction for the composite of cardiovascular deaths, hospitalizations for heart failure, and urgent visits for heart failure (N Engl J Med. 2021 Jan 14;384[2]:129-39). Patient follow-up in SCORED was not as long as originally planned when the study stopped early due to a loss of funding from a sponsor that was triggered by the COVID-19 pandemic.

MACE results ‘heterogeneous’ from SGLT2 inhibitors

Sotagliflozin and agents from the SGLT2 inhibitor class “have been consistent” in their benefits for reducing cardiovascular death and hospitalization for heart failure, but for MACE, the results from the SGLT2 inhibitors “have been more heterogeneous,” and the effect of sotagliflozin on MACE “were different in SCORED,” commented Michelle L. O’Donoghue, MD, MPH, a cardiologist at Brigham and Women’s Hospital in Boston who was not involved with this work.

Mitchel L. Zoler/MDedge News

“The results suggest a benefit [from sotagliflozin] on atherosclerotic events, which could be a potential advantage” compared with the SGLT2 inhibitors, “but the heterogeneity of this effect” among these agents means that more confirmatory data are needed for sotagliflozin, Dr. O’Donoghue said in an interview.

“There is a lot of enthusiasm for the concept” of combined inhibition of the SGLT1 and 2 receptors, and if more evidence for unique benefits of this effect accumulate “it may lead to increased enthusiasm for sotagliflozin,” she said. “A lot will also depend on pricing decisions” for sotagliflozin, if it receives U.S. marketing approval from the Food and Drug Administration. Decisions about which agent from the SGLT2 inhibitor class to prescribe “are often being made based on price right now,” Dr. O’Donoghue said.

Lexicon Pharmaceuticals, the company developing sotagliflozin, has announced plans to resubmit its new drug application for sotagliflozin to the FDA later in 2022, with the agency’s approval decision likely occurring late in 2022 or sometime during 2023. In February, the company withdrew its December 2021 application to correct a “technical issue” it had found.

An additional analysis reported by Dr. Bhatt used combined data from SCORED as well as several additional randomized trials of sotagliflozin involving a total of more than 20,000 patients that showed a significant 21% reduction in the incidence of MACE compared with placebo.

During his talk, Dr. Bhatt said that sotagliflozin was potentially superior to the agents that inhibit only SGLT2. In an interview, he based this tentative assessment on at least four attributes of sotagliflozin that have emerged from trial results:

• The drug’s ability to significantly reduce MACE and to have this effect apparent within a few months of treatment onset;
• The significantly reduced rate of stroke with sotagliflozin (when patients are not subdivided into those with or without a history of CVD) that has not yet been seen with any SGLT2 inhibitor;
• The ability of sotagliflozin to reduce hemoglobin A1c levels in patients with type 2 diabetes even when their estimated glomerular filtration rate is less than 30 mL/min per 1.73 m², an effect not seen with SGLT2 inhibitors and possibly explained by sotagliflozin having an effect on gut absorption of glucose in addition to its SGLT2 inhibitory effect in the kidney;
• And the proven ability of sotagliflozin to be safe and effective when initiated in patients hospitalized for heart failure, a property that so far has only also been shown for the SGLT2 inhibitor empagliflozin in the EMPULSE trial (Nature Med. 2022 Mar;28: 568-74).

SCORED was sponsored by Sanofi and Lexicon Pharmaceuticals, the companies originally developing sotagliflozin, although with the withdrawal of Sanofi’s support, further development is now sponsored entirely by Lexicon. Dr. Bhatt received research funding from Sanofi and Lexicon that was paid to Brigham and Women’s Health, and he has been an advisor to numerous companies. Dr. O’Donoghue has been a consultant to Amgen, Janssen, and Novartis, and has received research funding from Amgen, AZ MedImmune, Intarcia, Janssen, Merck, and Novartis.

O’Donoghue, MD, MPH, a cardiologist at Brigham and Women’s Hospital in Boston who was not involved with this work.

“The results suggest a benefit [from sotagliflozin] on atherosclerotic events, which could be a potential advantage” compared with the SGLT2 inhibitors, “but the heterogeneity of this effect” among these agents means that more confirmatory data are needed for sotagliflozin, Dr. O’Donoghue said in an interview.

“There is a lot of enthusiasm for the concept” of combined inhibition of the SGLT1 and 2 receptors, and if more evidence for unique benefits of this effect accumulate “it may lead to increased enthusiasm for sotagliflozin,” she said. “A lot will also depend on pricing decisions” for sotagliflozin, if it receives U.S. marketing approval from the Food and Drug Administration. Decisions about which agent from the SGLT2 inhibitor class to prescribe “are often being made based on price right now,” Dr. O’Donoghue said.

Lexicon Pharmaceuticals, the company developing sotagliflozin, has announced plans to resubmit its new drug application for sotagliflozin to the FDA later in 2022, with the agency’s approval decision likely occurring late in 2022 or sometime during 2023. In February, the company withdrew its December 2021 application to correct a “technical issue” it had found.

An additional analysis reported by Dr. Bhatt used combined data from SCORED as well as several additional randomized trials of sotagliflozin involving a total of more than 20,000 patients that showed a significant 21% reduction in the incidence of MACE compared with placebo.

During his talk, Dr. Bhatt said that sotagliflozin was potentially superior to the agents that inhibit only SGLT2. In an interview, he based this tentative assessment on at least four attributes of sotagliflozin that have emerged from trial results:

• The drug’s ability to significantly reduce MACE and to have this effect apparent within a few months of treatment onset;
• The significantly reduced rate of stroke with sotagliflozin (when patients are not subdivided into those with or without a history of CVD) that has not yet been seen with any SGLT2 inhibitor;
• The ability of sotagliflozin to reduce hemoglobin A1c levels in patients with type 2 diabetes even when their estimated glomerular filtration rate is less than 30 mL/min per 1.73 m², an effect not seen with SGLT2 inhibitors and possibly explained by sotagliflozin having an effect on gut absorption of glucose in addition to its SGLT2 inhibitory effect in the kidney;
• And the proven ability of sotagliflozin to be safe and effective when initiated in patients hospitalized for heart failure, a property that so far has only also been shown for the SGLT2 inhibitor empagliflozin in the EMPULSE trial (Nature Med. 2022 Mar;28: 568-74).

SCORED was sponsored by Sanofi and Lexicon Pharmaceuticals, the companies originally developing sotagliflozin, although with the withdrawal of Sanofi’s support, further development is now sponsored entirely by Lexicon. Dr. Bhatt received research funding from Sanofi and Lexicon that was paid to Brigham and Women’s Health, and he has been an advisor to numerous companies. Dr. O’Donoghue has been a consultant to Amgen, Janssen, and Novartis, and has received research funding from Amgen, AZ MedImmune, Intarcia, Janssen, Merck, and Novartis.
 

WASHINGTON – Results from new analyses further fleshed out the potent effect by the investigational SGLT1&2 inhibitor sotagliflozin on major cardiovascular adverse events in patients with type 2 diabetes, chronic kidney disease, and at high risk for cardiovascular disease in the SCORED trial that randomized more than 10,000 patients.

In prespecified, secondary analyses of the SCORED results, treatment with sotagliflozin during a median of 16 months was linked to a significant 21% risk reduction relative to placebo for the combined incidence of total major adverse cardiovascular events (MACE), which included cardiovascular death, first and recurrent episodes of nonfatal MI, and nonfatal stroke among the 5,144 randomized patients who entered the trial with a history of cardiovascular disease (CVD), Deepak L. Bhatt, MD, said at the annual scientific sessions of the American College of Cardiology.

Among the 5,440 patients in the study who did not have a history of CVD (although they did have at least one major risk factor or at least two minor risk factors), treatment with sotagliflozin was linked to a significant 26% relative risk reduction in total MACE events.

Part of these overall MACE benefits resulted from similar improvements from sotagliflozin treatment on the individual outcomes of total nonfatal MI and total nonfatal strokes. Treatment with sotagliflozin cut these MIs by a significant 31% in patients with a history of CVD relative to patients who received placebo, and by a relative 34% in those without a CVD event in their history, a difference compared with placebo that fell short of significance, said Dr. Bhatt, professor of medicine at Harvard Medical School and executive director of interventional cardiovascular programs at Brigham and Women’s Health, both in Boston.

Treatment with sotagliflozin also cut total nonfatal strokes by 31% relative to placebo in patients with a history of CVD, and by a relative 38% in those without a CVD history. Both differences fell short of significance.
 

An early MACE benefit and a stroke benefit

“This stroke benefit has not been clearly seen” with any agent from the closely related sodium-glucose cotransport-2 (SGLT2) inhibitor class, and “the MACE benefit appeared very early,” within 3 months from the start of sotagliflozin treatment, “which may be because of the SGLT1 inhibition,” Dr. Bhatt said during his report.

The SGLT1 receptor is the primary mechanism cells in the gut use to absorb glucose and galactose in the human gastrointestinal tract, Dr. Bhatt explained, while the SGLT2 receptor appears on kidney cells and is the major player in the reabsorption of filtered glucose. The SGLT2 inhibitor class includes the agents canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance), while sotagliflozin inhibits both SGLT1 and SGLT2.

Main results from SCORED appeared in a report first released in late 2020, and showed that for the study’s primary endpoint treatment with sotagliflozin linked with a significant 26% relative risk reduction for the composite of cardiovascular deaths, hospitalizations for heart failure, and urgent visits for heart failure (N Engl J Med. 2021 Jan 14;384[2]:129-39). Patient follow-up in SCORED was not as long as originally planned when the study stopped early due to a loss of funding from a sponsor that was triggered by the COVID-19 pandemic.

The U.S. Food and Drug Administration has approved a higher 2-mg dose of the GLP-1 agonist semaglutide (Ozempic, Novo Nordisk) for adults with type 2 diabetes, giving a higher-dose alternative to the previous maximum 1-mg dose of semaglutide, administered by subcutaneous injection once weekly.

Semaglutide is currently available as 0.5-mg and 1-mg doses.

Results from the pivotal SUSTAIN FORTE study of the 2-mg dose (which, like lower-dose semaglutide for type 2 diabetes, comes in a single-use pen injector) showed that when compared head-to-head with a 1-mg/week dose in a 40-week study with 961 randomized patients, the 2-mg regimen led to a significant average incremental reduction in A1c levels of 0.23 percentage points. The 2-mg dose also produced a significant incremental increase in weight loss, with patients losing 0.93 kg more on the higher dose.

The 2-mg dose gives patients with type 2 diabetes and clinicians an “additional option” when a bigger “shift” in blood glucose is needed, said Juan Pablo Frias, MD, National Research Institute, Los Angeles, California, who was lead investigator for SUSTAIN FORTE, in a written statement.

As well as reducing glucose levels, semaglutide has been shown to reduce the risk of major cardiovascular events in adults with type 2 diabetes and known cardiovascular disease.

Semaglutide was approved as a 2.4-mg injectable dose, as Wegovy, in 2021 for weight loss in patients with overweight or obesity.

SUSTAIN FORTE and other trials of semaglutide were sponsored by Novo Nordisk. SURPASS-2 and other trials of tirzepatide were sponsored by Lilly. Dr. Frias was lead investigator for both SUSTAIN FORTE and SURPASS-2, as well as an investigator for other trials sponsored by Lilly, Novo Nordisk, and other companies.

Researchers running the EMPA-KIDNEY trial that’s been testing the safety and efficacy of the SGLT2 inhibitor empagliflozin (Jardiance) in about 6,600 patients with chronic kidney disease (CKD) announced on March 16 that they had stopped the trial early because of positive efficacy that met the study’s prespecified threshold for early termination.

EMPA-KIDNEY is the third major trial of an agent from the sodium-glucose cotransport 2 (SGLT2) inhibitor class tested in patients with CKD to be stopped early because of positive results that met a prespecified termination rule.

EMPA-KIDNEY enrolled a wider range of patients

EMPA-KIDNEY expands the scope of types of patients with CKD now shown to benefit from treatment with an SGLT2 inhibitor. CREDENCE tested canagliflozin only in patients with type 2 diabetes and diabetic nephropathy, and in DAPA-CKD, two-thirds of enrolled patients had type 2 diabetes, and all had CKD. In EMPA-KIDNEY, 46% of the 6,609 enrolled patients had diabetes (including a very small number with type 1 diabetes).

Another departure from prior studies of an SGLT2 inhibitor for patients selected primarily for having CKD was that in EMPA-KIDNEY, 20% of patients did not have albuminuria, and for 34%, eGFR at entry was less than 30 mL/min/1.73 m², with all enrolled patients required to have an eGFR at entry of greater than or equal to 20 mL/min/1.73 m². Average eGFR in EMPA-KIDNEY was about 38 mL/min/1.73 m². To be included in the trial, patients were not required to have albuminuria, except those whose eGFR was greater than or equal to 45 mL/min/1.73 m².

In DAPA-CKD, the minimum eGFR at entry had to be greater than or equal to 25 mL/min/1.73 m², and roughly 14% of enrolled patients had an eGFR of less than 30 mL/min/1.73 m². The average eGFR in DAPA-CKD was about 43 mL/min/1.73 m². In addition, all patients had at least microalbuminuria, with a minimum urinary albumin-to-creatinine ratio of 200. In CREDENCE, the minimum eGFR for enrollment was 30 mL/min/1.73 m², and the average eGFR was about 56 mL/min/1.73 m². All patients in CREDENCE had to have macroalbuminuria, with a urinary albumin-to-creatinine ratio of more than 300.

According to the researchers who designed EMPA-KIDNEY, the trial enrollment criteria aimed to include adults with CKD “who are frequently seen in practice but were under-represented in previous SGLT2 inhibitor trials.”

Indications for empagliflozin are expanding

The success of empagliflozin in EMPA-KIDNEY follows its positive results in both the EMPEROR-Reduced and EMPEROR-Preserved trials, which collectively proved the efficacy of the agent for patients with heart failure regardless of their left ventricular ejection fraction and regardless of whether they also had diabetes.

These results led the U.S. Food and Drug Administration to recently expand the labeled indication for empagliflozin to all patients with heart failure. Empagliflozin also has labeled indications for glycemic control in patients with type 2 diabetes and to reduce the risk of cardiovascular death in adults with type 2 diabetes and established cardiovascular disease.

As of today, empagliflozin has no labeled indication for treating patients with CKD. Dapagliflozin received that indication in April 2021, and canagliflozin received an indication for treating patients with type 2 diabetes, diabetic nephropathy, and albuminuria in September 2019.

EMPA-KIDNEY is sponsored by Boehringer Ingelheim and Lilly, the two companies that jointly market empagliflozin (Jardiance).

New signals of a potential additive benefit from the nonsteroidal mineralocorticoid antagonist finerenone (Kerendia) and a sodium-glucose transporter 2 inhibitor in patients with type 2 diabetes and chronic kidney disease (CKD) emerged in a follow-up report from the FIDELITY analysis, which combined data from more than 13,000 patients who received finerenone in either of the two pivotal trials with the agent.

The analysis showed that the 877 patients enrolled in either the FIDELIO DKD or FIGARO DKD trials taking an SGLT2 inhibitor at baseline had a 37% relative reduction in their urinary albumin-to-creatinine ratio (UACR), compared with placebo-treated patients after a median of 3 years on treatment.

Among the remaining 12,149 patients who did not receive an SGLT2 inhibitor, finerenone cut the average UACR by 32%, compared with placebo, said Peter Rossing, DMSc, MD, who presented the findings on Feb. 27 at the World Congress of Nephrology 2022 in Kuala Lumpur, Malaysia.

Primary endpoint results for FIDELIO-DKD and FIGARO-DKD also suggest similar additive effects of finerenone plus an SGLT2 inhibitor.

Results of the composite renal endpoint in each study – progression to kidney failure, renal death, or at least a 57% decline in estimated glomerular filtration rate (eGFR) from baseline – showed a 58% relative risk reduction in patients who received agents from both drug classes and a 20% relative risk reduction in those who only received finerenone, a between-group difference that was not significant.

For the composite cardiovascular event endpoint – cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure – the rate fell by 37%, compared with placebo, in patients who also received an SGLT2 inhibitor, and by 13%, compared with placebo, in those who received finerenone but no SGLT2 inhibitor, also a difference that was not significant.

‘A lot of interest in finerenone’ in U.S.

“The benefits of finerenone on cardiovascular and kidney outcomes were consistent, irrespective of SGLT2 inhibitor use at baseline,” concluded Dr. Rossing, professor and head of research at the Steno Diabetes Center in Copenhagen.

The new findings are a “suggestion that the two classes might be additive [in their effects], but more data are needed,” Dr. Rossing said during his presentation.

But he cautioned that in both pivotal trials randomization did not consider SGLT2 inhibitor use. All patients in the two trials were already receiving a renin-angiotensin system (RAS) inhibitor as background treatment, either an ACE inhibitor or angiotensin-receptor blocker.

The consequence of treatment with finerenone combined with an SGLT2 inhibitor is of growing importance because “an SGLT2 inhibitor is now recommended in most guidelines” for the type of patients enrolled in the two finerenone trials, explained Dr. Rossing.

He also noted that the first guideline to recommend routine use of finerenone in indicated patients appeared recently in the annual update to Standards of Medical Care in Diabetes – 2022 published by the American Diabetes Association.

The 2022 Standards states: “In patients with CKD who are at increased risk for cardiovascular events or CKD progression or are unable to use an SGLT2 inhibitor, a nonsteroidal mineralocorticoid receptor antagonist (finerenone) is recommended to reduce CKD progression and cardiovascular events.”

Results from FIDELIO-DKD, reported in the New England Journal of Medicine in 2020, and the main study, FIGARO-DKD, published in the same journal in 2021, led the Food and Drug Administration to approve finerenone in July 2021 to slow the progression of renal disease in patients with type 2 diabetes and CKD.

“My impression is that in the United States there is a lot of interest in finerenone,” Dr. Rossing said during the discussion following his presentation.

Finerenone has also been recently approved in the European Union.
 

‘Consistent’ benefits irrespective of SGLT2 inhibitors

“The cardiovascular and kidney benefits of finerenone were consistent irrespective of SGLT2 inhibitor use. This is definitely interesting and warrants a randomized controlled trial” to examine the relationship in a more rigorous way, commented Tejas Desai, MD, a nephrologist with the Department of Veterans Affairs, Charlotte, N.C.

That study, CONFIDENCE, is on its way, Dr. Rossing said during his talk. The randomized phase 2 trial has a planned enrollment of 800 patients with type 2 diabetes and CKD and three treatment groups: finerenone plus placebo, the SGLT2 inhibitor empagliflozin (Jardiance) plus placebo, or finerenone plus empagliflozin. The study will launch later in 2022 and has a planned completion date of late 2023.

“SGLT2 inhibitors, compared with finerenone, is where all of this is headed. We need a large trial that adjudicates the best medication to use with a RAS inhibitor,” Dr. Desai said in an interview.

The new analyses from the combined FIDELITY study expand on a previous report presented at the 2021 annual congress of the European Society of Cardiology and published in the European Heart Journal.
 

‘Impressive’ effect on cardiovascular events

The main findings from FIDELITY presented in those earlier reports, in 13,026 patients, showed there was a significant 14% relative reduction in the composite cardiovascular endpoint with finerenone, compared with placebo, during a median 3 years of follow-up.

The same report documented, in the total combined cohort, a significant 23% relative reduction in the composite renal endpoint in those taking finerenone compared with placebo.

“Reducing the risk of cardiovascular endpoints by a relative 14% is impressive,” and the time course showed a “relatively quick onset of action,” Dr. Desai noted.

He also characterized the enrolled patients, which included many with stage 3 or 4 CKD, as “not the sickest population of patients with CKD,” but rather “relatively healthier patients with CKD.”

Dr. Desai also downplayed the importance of the observed reduction in UACR associated with finerenone in FIDELITY.

“UACR is a surrogate marker. Results from many studies have shown improvements in UACR only to not show protection against falls in eGFR rate,” Dr. Desai said.

He was also reassured by the low incidence of hyperkalemia that led to discontinuation, which occurred in 1.7% of patients taking finerenone and in 0.6% of those taking placebo.

The types of patients enrolled in FIDELIO-DKD and FIGARO-DKD, who did not have eGFR rates below 25 mL/min per 1.73 m², are not particularly susceptible to this adverse effect, he said, noting, “I’m not overly concerned with hyperkalemia in this CKD population.

“I’m more concerned about [hyperkalemia in] patients with CKD and an eGFR of less than 25 mL/min per 1.73 m², but this was less than 1% of the enrolled population,” Dr. Desai observed.

FIDELIO-DKD, FIGARO-DKD, and FIDELITY were sponsored by Bayer, which markets finerenone (Kerendia). Dr. Rossing reported being a consultant for Bayer and other drug companies, and receiving research funding from AstraZeneca and Novo Nordisk. Dr. Desai reported no relevant financial relationships.

New signals of a potential additive benefit from the nonsteroidal mineralocorticoid antagonist finerenone (Kerendia) and a sodium-glucose transporter 2 inhibitor in patients with type 2 diabetes and chronic kidney disease (CKD) emerged in a follow-up report from the FIDELITY analysis, which combined data from more than 13,000 patients who received finerenone in either of the two pivotal trials with the agent.

The analysis showed that the 877 patients enrolled in either the FIDELIO DKD or FIGARO DKD trials taking an SGLT2 inhibitor at baseline had a 37% relative reduction in their urinary albumin-to-creatinine ratio (UACR), compared with placebo-treated patients after a median of 3 years on treatment.

Among the remaining 12,149 patients who did not receive an SGLT2 inhibitor, finerenone cut the average UACR by 32%, compared with placebo, said Peter Rossing, DMSc, MD, who presented the findings on Feb. 27 at the World Congress of Nephrology 2022 in Kuala Lumpur, Malaysia.

Primary endpoint results for FIDELIO-DKD and FIGARO-DKD also suggest similar additive effects of finerenone plus an SGLT2 inhibitor.

Results of the composite renal endpoint in each study – progression to kidney failure, renal death, or at least a 57% decline in estimated glomerular filtration rate (eGFR) from baseline – showed a 58% relative risk reduction in patients who received agents from both drug classes and a 20% relative risk reduction in those who only received finerenone, a between-group difference that was not significant.

For the composite cardiovascular event endpoint – cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure – the rate fell by 37%, compared with placebo, in patients who also received an SGLT2 inhibitor, and by 13%, compared with placebo, in those who received finerenone but no SGLT2 inhibitor, also a difference that was not significant.

‘A lot of interest in finerenone’ in U.S.

“The benefits of finerenone on cardiovascular and kidney outcomes were consistent, irrespective of SGLT2 inhibitor use at baseline,” concluded Dr. Rossing, professor and head of research at the Steno Diabetes Center in Copenhagen.

The new findings are a “suggestion that the two classes might be additive [in their effects], but more data are needed,” Dr. Rossing said during his presentation.

But he cautioned that in both pivotal trials randomization did not consider SGLT2 inhibitor use. All patients in the two trials were already receiving a renin-angiotensin system (RAS) inhibitor as background treatment, either an ACE inhibitor or angiotensin-receptor blocker.

The consequence of treatment with finerenone combined with an SGLT2 inhibitor is of growing importance because “an SGLT2 inhibitor is now recommended in most guidelines” for the type of patients enrolled in the two finerenone trials, explained Dr. Rossing.

He also noted that the first guideline to recommend routine use of finerenone in indicated patients appeared recently in the annual update to Standards of Medical Care in Diabetes – 2022 published by the American Diabetes Association.

The 2022 Standards states: “In patients with CKD who are at increased risk for cardiovascular events or CKD progression or are unable to use an SGLT2 inhibitor, a nonsteroidal mineralocorticoid receptor antagonist (finerenone) is recommended to reduce CKD progression and cardiovascular events.”

Results from FIDELIO-DKD, reported in the New England Journal of Medicine in 2020, and the main study, FIGARO-DKD, published in the same journal in 2021, led the Food and Drug Administration to approve finerenone in July 2021 to slow the progression of renal disease in patients with type 2 diabetes and CKD.

“My impression is that in the United States there is a lot of interest in finerenone,” Dr. Rossing said during the discussion following his presentation.

Finerenone has also been recently approved in the European Union.
 

‘Consistent’ benefits irrespective of SGLT2 inhibitors

“The cardiovascular and kidney benefits of finerenone were consistent irrespective of SGLT2 inhibitor use. This is definitely interesting and warrants a randomized controlled trial” to examine the relationship in a more rigorous way, commented Tejas Desai, MD, a nephrologist with the Department of Veterans Affairs, Charlotte, N.C.

That study, CONFIDENCE, is on its way, Dr. Rossing said during his talk. The randomized phase 2 trial has a planned enrollment of 800 patients with type 2 diabetes and CKD and three treatment groups: finerenone plus placebo, the SGLT2 inhibitor empagliflozin (Jardiance) plus placebo, or finerenone plus empagliflozin. The study will launch later in 2022 and has a planned completion date of late 2023.

“SGLT2 inhibitors, compared with finerenone, is where all of this is headed. We need a large trial that adjudicates the best medication to use with a RAS inhibitor,” Dr. Desai said in an interview.

Key takeaways

• in analyses of more than 100,000 women that used Mendelian randomization (MR) as a tool to reduce residual confounding.
• The MR analyses showed no significant association between ANM and breast cancer, endometrial cancer, ovarian cancer, coronary heart disease, ischemic stroke, and Alzheimer’s disease.
• The clear lack of a causal effect of ANM on the outcomes of coronary heart disease and ischemic stroke in the MR analyses despite a strong inverse association seen in the observational data of this study (without MR) suggests residual confounding plays a substantial role in driving the observed outcomes.

Why this matters

• The authors said that, to their knowledge, this is the first study that has shown a causal association between older ANM and higher risk of postmenopausal lung cancer.
• This finding was directionally opposite to the significant protective effect of increased ANM documented in an observational analysis of roughly the same data as well as prior reports that did not use MR. This “notable inconsistency” suggests very substantial residual confounding without MR that could be driven by factors such as smoking, diet, and exercise.
• If these results are replicated in additional datasets, it would highlight a need for randomized, controlled trials of antiestrogen therapies in postmenopausal women for the prevention or treatment of lung cancer.

Study design

• The study included data from 106,853 postmenopausal women enrolled in the Women’s Health Initiative (WHI) and 95,464 women who were 37-73 years old included in the UK Biobank (UKB). Analyses for each outcome also included data from smaller numbers of women obtained from several additional datasets.
• The MR analysis used up to 55 single-nucleotide polymorphisms previously discovered through a genome-wide association study of about 70,000 women of European ancestry and independent of all datasets analyzed in the current study. The authors included all single-nucleotide polymorphisms with a consistent direction of effect on ANM.
• The MR analysis for lung cancer included 113,371 women from the two primary datasets and an additional 3012 women from six additional datasets.
• The MR analysis for bone fracture involved 113,239 women from the WHI and UKB only. The MR analysis for osteoporosis involved 137,080 women from the WHI, UKB, and one additional external dataset.

Key results

• Results from a meta-analysis of the MR results using data from the WHI, UKB, and the additional datasets showed ANM was causally associated with an increased risk of lung cancer by an odds ratio of 1.35 for each 5-year increase in ANM. In contrast, the adjusted observational analysis of data just from the WHI and UKB showed a significant 11% relative risk reduction in the incidence of lung cancer for each 5-year increase in ANM.
• The MR results also showed causally protective effects for fracture, with a 24% relative risk reduction, and for osteoporosis, with a 19% relative risk reduction for each 5-year increase in ANM.
• The MR analyses showed no significant association between AMN and outcome for breast cancer, endometrial cancer, ovarian cancer, coronary heart disease, ischemic stroke, and Alzheimer’s disease.

Limitations

The main limitation of the MR study was the potential for inadequate power for assessing some outcomes despite the large overall size of the study cohort. Lack of adequate power may be responsible for some of the nonsignificant associations seen in the study, such as for breast and endometrial cancers, where substantial prior evidence has implicated increased risk through the effects of prolonged exposure to endogenous or exogenous estrogens.

The healthy cohort effect in the UKB is a known weakness of this dataset that may have limited the number of cases and generalizability of findings.

Osteoporosis and Alzheimer’s disease were self-reported.

The study only included participants of European ancestry because most subjects in most of the cohorts examined were White women and the applied MR instruments were found by genome-wide association studies run predominantly in White women. The authors said the causal effects of ANM need study in more diverse populations.
