Campaigners for greater transparency in medical science have reiterated calls for more to be done to avoid “medical research waste” after an investigation found that results from more than a fifth of clinical trials across five Nordic countries have never been made public.

A study found that results from 475 clinical trials in Denmark, Iceland, Finland, Norway, and Sweden — involving almost 84,000 participants — were never made public in any form.

Nonpublication of clinical trial results wastes public money, harms patients, and undermines public health, the researchers said. 

There is already a well-defined ethical responsibility to publish trial results. Article 36 of the Declaration of Helsinki on Ethical Principles for Medical Research Involving Human Subjects states that “researchers have a duty to make publicly available the results of their research on human subjects,” and World Health Organization best practice protocols call for results to be uploaded onto trial registries within 12 months of trial completion.
 

Research Waste Is a ‘Pervasive Problem’

So, how and why do so many trials end up gathering dust in a drawer? The latest study, published February 5 as a preprint, evaluated the reporting outcomes of 2113 clinical trials at medical universities and university hospitals in Nordic countries between 2016 and 2019. It found that across the five countries, 22% of all clinical trial results had not been shared. Furthermore, only 27% of all trial results were made public, either on registries or in journals, within 12 months. Even 2 years after trials ended, only around half of results (51.7%) had been put into the public domain.

The authors concluded that missing and delayed results from academically-led clinical trials was a “pervasive problem” in Nordic countries and that institutions, funding bodies, and policymakers needed to ensure that regulations around reporting results were adhered to so that important findings are not lost.

Study first author, Gustav Nilsonne, MD, PHD, from the Department of Clinical Neuroscience at the Karolinska Institutet, Sweden, told this news organization: “Most people I talk to — most colleagues who are clinical scientists — tend to think that the main reason is that negative results are not as interesting to publish and therefore they get lower priority, and they get published later and sometimes not at all.”

Experts stressed that the problem is not confined to Nordic countries and that wasted medical research persists elsewhere in Europe and remains a global problem. For instance, a report published in the Journal of Clinical Epidemiology found that 30% of German trials completed between 2014 and 2017 remained unpublished 5 years after completion.
 

The Case for Laws, Monitoring, and Fines

Till Bruckner, PHD, from TranspariMED, which campaigns to end evidence distortion in medicine, told this news organization: “What is needed to comprehensively fix the problem is a national legal requirement to make all trial results public, coupled with effective monitoring, and followed by sanctions in the rare cases where institutions refuse to comply.” 

Dr. Nilsonne added: “We have argued that the sponsors need to take greater responsibility, but also that there needs to be somebody whose job it is to monitor clinical trials reporting. It shouldn’t have to be that we do this as researchers on a shoestring with no dedicated resources. It should be somebody’s job.”

Since January 31, 2023, all initial clinical trial applications in the European Union must be submitted through the EU Clinical Trials Information System. Dr. Bruckner said that “the picture is not yet clear” in Europe, as the first trial results under the system are not expected until later this year. Even then, enforcement lies with regulators in individual countries. And while Denmark has already indicated it will enforce the regulations, he warned that other countries “might turn a blind eye.”

He pointed out that existing laws don’t apply to all types of trials. “That means that for many trials, nobody is legally responsible for ensuring that results are made public, and no government agency has any oversight or mandate,” he said.

Outside the EU, the United Kingdom has helped lead the way through the NHS Health Research Authority (HRA), which registers trials run in the country. One year after a trial has been completed, the HRA checks to see if the results have been uploaded to the registry and issues reminders if they haven’t.

In an update of its work in January, the authority said that compliance had hovered at just below 90% between 2018 and 2021 but that it was working to increase this to 100% by working with stakeholders across the research sector.

Dr. Nilsonne considers the UK system of central registration and follow-up an attractive option. “I would love to see something along those lines in other countries too,” he said.
 

‘Rampant Noncompliance’ in the United States

In the United States, a requirement to make trial results public is backed by law. Despite this, there’s evidence of “rampant noncompliance” and minimal government action, according to Megan Curtin from Universities Allied for Essential Medicines (UAEM), which has been tracking the issue in the United States and working to push universities and others to make their findings available.

The US Food and Drug Administration (FDA) shares responsibility with the National Institutes of Health for enforcement of clinical trial results reporting, but the UAEM says nearly 4000 trials are currently out of compliance with reporting requirements. In January last year, the UAEM copublished a report with the National Center for Health Research and TranspariMED, which found that 3627 American children participated in clinical trials whose results remain unreported.

The FDA can levy a fine of up to $10,000 USD for a violation of the law, but UAEM said that, as of January 2023, the FDA had sent only 92 preliminary notices of noncompliance and four notices of noncompliance. “A clear difference between the EU field of clinical trial operation and US clinical trials is that there are clear laws for reporting within 12 months, which can be enforced, but they’re not being enforced by the FDA,” Ms. Curtin told this news organization.

The UAEM is pushing the FDA to issue a minimum of 250 preliminary notices of noncompliance each year to noncompliant trial sponsors.

Dr. Nilsonne said: “I do believe we have a great responsibility to the patients that do contribute. We need to make sure that the harms and risks that a clinical trial entails are really balanced by knowledge gain, and if the results are never reported, then we can’t have a knowledge gain.”

Among patients with psoriasis, the risk of mortality was strongly associated with hepatic injury, cardiovascular disease, and psychiatric affective disorders, but was reduced among those who received systemic therapy with biologics, researchers from Canada report.

Those are key findings from a large retrospective registry study of patients with psoriasis, published in The Journal of the American Academy of Dermatology.

“Psoriasis, a chronic inflammatory condition affecting approximately 3% of the western populations, bears a higher risk of mortality compared to healthy individuals, possibly by inducing systemic inflammation associated with numerous comorbidities, especially cardiovascular diseases, metabolic syndrome, and others,” wrote corresponding author Robert Gniadecki, MD, PhD, of the division of dermatology at the University of Alberta, Canada, and colleagues. “It has been argued that the use of systemic immunomodulatory agents quenches systemic inflammation and potentially improves patient survival. However, the evidence to support this hypothesis is limited.”

To investigate the impact of comorbidities and systemic therapies on all-cause mortality in psoriasis, the researchers used the Alberta Health Services Data Repository of Reporting database from January 1, 2012, to June 1, 2019, which represents a population base of 4.47 million individuals. They extracted data on 18,618 psoriasis cases and 55,854 controls, stratified cases according to the Charlson Comorbidity Index (CCI), a surrogate measure for comorbidity burden, and by the type of therapy received, and conducted statistical analyses including Cox proportional hazards regression to determine absolute hazard ratios representing relative effects of specific demographic and comorbidity factors on mortality within groups.

The median age in both cohorts was 48 years, and 51% were male. The researchers observed that mortality in the psoriasis cohort was significantly higher than in the controls (5.7% vs. 3.8%, respectively; P < .05), with a median age at the time of death of 72 vs. 74.4 years.

The CCI and comorbidities strongly predicted mortality, especially drug-induced liver injury (hazard ratio [HR], 1.78), bipolar disorder and suicidal ideation (HR, 1.24-1.58), and major cardiovascular diseases, which included myocardial infarction (MI), congestive heart failure (CHF), and cerebrovascular disease (CVA) (HR, 1.2-1.4).

Among patients in the psoriasis cohort, survival of those treated with biologic agents was higher than in controls, even after matching for CCI (3.2% vs. 4.4%, respectively, P < .05). “These patients also exhibit reduced overall mortality compared to those treated with methotrexate or topical agents,” Dr. Gniadecki and colleagues wrote. “There was no difference in mortality between methotrexate patients and the topical therapy patients, but any of those treatment groups had superior survival compared to the no-treatment cohort.”

They added that despite better survival among patients treated with biologic agents, no significant improvements were detected in their comorbidity profiles. “Notably, the frequency of major cardiovascular disease (MI, CHF, CVA) was the same as in the controls, and overall, the frequency of diseases coded as cardiovascular was slightly increased,” they wrote.

The fact that some factors could not be measured, including the type and severity of psoriasis, response to treatment, smoking history, and alcohol intake, was a study limitation, they noted.

Joel M. Gelfand, MD, director of the psoriasis and phototherapy treatment center at the University of Pennsylvania, Philadelphia, who was asked to comment on the analysis, said the study confirms prior work indicating that having psoriasis is a predictor of mortality. In addition, “there is a strong healthy user affect among patients who take and stay on biologics for psoriasis,” he told this news organization.

A group of 16 Democratic legislators on the House Committee on Oversight and Reform has demanded in a letter that the drugmaker Pfizer present details on how the company is responding to shortages of the generic chemotherapy drugs carboplatin, cisplatin, and methotrexate.

In a statement about their February 21 action, the legislators, led by Rep. Jamie Raskin (D-Md.), the committee’s ranking minority member, described their work as a follow up to an earlier investigation into price hikes of generic drugs. While the committee members queried Pfizer over the three oncology medications only, they also sent letters to drugmakers Teva and Sandoz with respect to shortages in other drug classes.

A representative for Pfizer confirmed to MDedge Oncology that the company had received the representatives’ letter but said “we have no further details to provide at this time.”

What is the basis for concern?

All three generic chemotherapy drugs are mainstay treatments used across a broad array of cancers. Though shortages have been reported for several years, they became especially acute after December 2022, when an inspection by the US Food and Drug Administration (FDA) led to regulatory action against an Indian manufacturer, Intas, that produced up to half of the platinum-based therapies supplied globally. The National Comprehensive Cancer Care Network reported in October 2023 that more than 90% of its member centers were struggling to maintain adequate supplies of carboplatin, and 70% had trouble obtaining cisplatin, while the American Society of Clinical Oncology published clinical guidance on alternative treatment strategies.

What has the government done in response to the recent shortages?

The White House and the FDA announced in September that they were working with several manufacturers to help increase supplies of the platinum-based chemotherapies and of methotrexate, and taking measures that included relaxing rules on imports. Recent guidance under a pandemic-era federal law, the 2020 CARES Act, strengthened manufacturer reporting requirements related to drug shortages, and other measures have been proposed. While federal regulators have many tools with which to address drug shortages, they cannot legally oblige a manufacturer to increase production of a drug.

What can the lawmakers expect to achieve with their letter?

By pressuring Pfizer publicly, the lawmakers may be able to nudge the company to take measures to assure more consistent supplies of the three drugs. The lawmakers also said they hoped to glean from Pfizer more insight into the root causes of the shortages and potential remedies. They noted that, in a May 2023 letter by Pfizer to customers, the company had warned of depleted and limited supplies of the three drugs and said it was “working diligently” to increase output. However, the lawmakers wrote, “the root cause is not yet resolved and carboplatin, cisplatin, and methotrexate continue to experience residual delays.”

Why did the committee target Pfizer specifically?

Pfizer and its subsidiaries are among the major manufacturers of the three generic chemotherapy agents mentioned in the letter. The legislators noted that “pharmaceutical companies may not be motivated to produce generic drugs like carboplatin, cisplatin, and methotrexate, because they are not as lucrative as producing patented brand name drugs,” and that “as a principal supplier of carboplatin, cisplatin, and methotrexate, it is critical that Pfizer continues to increase production of these life-sustaining cancer medications, even amidst potential lower profitability.”

The committee members also made reference to news reports of price-gouging with these medications, as smaller hospitals or oncology centers are forced to turn to unscrupulous third-party suppliers.

What is being demanded of Pfizer?

Pfizer was given until March 6 to respond, in writing and in a briefing with committee staff, to a six questions. These queries concern what specific steps the company has taken to increase supplies of the three generic oncology drugs, what Pfizer is doing to help avert price-gouging, whether further oncology drug shortages are anticipated, and how the company is working with the FDA on the matter.

Recent guidance under a pandemic-era federal law, the 2020 CARES Act, strengthened manufacturer reporting requirements related to drug shortages, and other measures have been proposed. While federal regulators have many tools with which to address drug shortages, they cannot legally oblige a manufacturer to increase production of a drug.

What can the lawmakers expect to achieve with their letter?

By pressuring Pfizer publicly, the lawmakers may be able to nudge the company to take measures to assure more consistent supplies of the three drugs. The lawmakers also said they hoped to glean from Pfizer more insight into the root causes of the shortages and potential remedies. They noted that, in a May 2023 letter by Pfizer to customers, the company had warned of depleted and limited supplies of the three drugs and said it was “working diligently” to increase output. However, the lawmakers wrote, “the root cause is not yet resolved and carboplatin, cisplatin, and methotrexate continue to experience residual delays.”

Why did the committee target Pfizer specifically?

Pfizer and its subsidiaries are among the major manufacturers of the three generic chemotherapy agents mentioned in the letter. The legislators noted that “pharmaceutical companies may not be motivated to produce generic drugs like carboplatin, cisplatin, and methotrexate, because they are not as lucrative as producing patented brand name drugs,” and that “as a principal supplier of carboplatin, cisplatin, and methotrexate, it is critical that Pfizer continues to increase production of these life-sustaining cancer medications, even amidst potential lower profitability.”

The committee members also made reference to news reports of price-gouging with these medications, as smaller hospitals or oncology centers are forced to turn to unscrupulous third-party suppliers.

What is being demanded of Pfizer?

Pfizer was given until March 6 to respond, in writing and in a briefing with committee staff, to a six questions. These queries concern what specific steps the company has taken to increase supplies of the three generic oncology drugs, what Pfizer is doing to help avert price-gouging, whether further oncology drug shortages are anticipated, and how the company is working with the FDA on the matter.

A group of 16 Democratic legislators on the House Committee on Oversight and Reform has demanded in a letter that the drugmaker Pfizer present details on how the company is responding to shortages of the generic chemotherapy drugs carboplatin, cisplatin, and methotrexate.

In a statement about their February 21 action, the legislators, led by Rep. Jamie Raskin (D-Md.), the committee’s ranking minority member, described their work as a follow up to an earlier investigation into price hikes of generic drugs. While the committee members queried Pfizer over the three oncology medications only, they also sent letters to drugmakers Teva and Sandoz with respect to shortages in other drug classes.

A representative for Pfizer confirmed to MDedge Oncology that the company had received the representatives’ letter but said “we have no further details to provide at this time.”

What is the basis for concern?

All three generic chemotherapy drugs are mainstay treatments used across a broad array of cancers. Though shortages have been reported for several years, they became especially acute after December 2022, when an inspection by the US Food and Drug Administration (FDA) led to regulatory action against an Indian manufacturer, Intas, that produced up to half of the platinum-based therapies supplied globally. The National Comprehensive Cancer Care Network reported in October 2023 that more than 90% of its member centers were struggling to maintain adequate supplies of carboplatin, and 70% had trouble obtaining cisplatin, while the American Society of Clinical Oncology published clinical guidance on alternative treatment strategies.

Patients with Cushing disease have an increased risk for new-onset autoimmune disease in the 3 years after surgical remission, according to a new retrospective study published on February 20 in Annals of Internal Medicine.

Outcomes for patients with Cushing disease were compared against those with nonfunctioning pituitary adenomas (NFPAs). New-onset autoimmune disease occurred in 10.4% with Cushing disease and 1.6% among patients with NFPA (hazard ratio, 7.80; 95% CI, 2.88-21.10).

“Understanding and recognizing new and recurrent autoimmune disease in this setting is important to avoid misclassifying such patients with glucocorticoid withdrawal syndrome, which could result in failure to treat underlying autoimmune disease, as well as erroneous diagnosis of steroid withdrawal cases,” wrote Dennis Delasi Nyanyo of Massachusetts General Hospital and Harvard Medical School, Boston, and colleagues.

Given the general population’s annual incidence of major autoimmune diseases, estimated at about 100 cases per 100,000 people, and the 3-year incidence of 10.4% found in this study’s cohort, “our findings suggest that Cushing disease remission may trigger development of autoimmune disease,” the authors wrote.
 

Monitor Patients With Family History of Autoimmune Disease?

The study results were not necessarily surprising to Anthony P. Heaney, MD, PhD, an endocrinologist and professor of medicine at the University of California, Los Angeles, because past research has raised similar questions. The authors’ suggestion that the rapid postsurgical drop in cortisol that occurs as a result of treating Cushing disease becomes some sort of autoimmune trigger is interesting but remains speculative, Dr. Heaney pointed out.

If future evidence supports that possibility, “it would suggest, in terms of managing those patients in the postoperative setting, that there may be some merit to giving them higher concentrations of glucocorticoids for a short period of time,” Dr. Heaney said, thereby bringing their levels down more gradually rather than taking them off a cliff, in a sense. Or, if more evidence bears out the authors’ hypothesis, another approach might be treating patients with medicine to bring down the cortisol before surgery, though there are challenges to that approach, Dr. Heaney said.

At the same time, those who developed new autoimmune disease remain a small subset of patients with Cushing disease, so such approaches may become only potentially appropriate to consider in patients with risk factors, such as a family history of autoimmune disease.

The researchers conducted a retrospective chart review of adult patients who underwent transsphenoidal surgery for either Cushing disease or NFPA at Massachusetts General Hospital between 2005 and 2019.

The study involved 194 patients with Cushing disease who had postsurgical remission and at least one follow-up visit with a pituitary expert and 92 patients with NFPA who were matched to patients with Cushing disease based on age and sex. The authors regarded autoimmune disease diagnosed within 36 months of the surgery to be temporally associated with Cushing disease remission. Among the autoimmune diseases considered were “rheumatoid arthritis, Sjögren syndrome, systemic lupus erythematosus, autoimmune thyroiditis, celiac disease, psoriasis, vitiligo, autoimmune neuropathy, multiple sclerosis, myasthenia gravis, and ulcerative colitis.”

Patients differed in average body mass index and tumor size, but family history of autoimmune disease was similar in both groups. Average BMI was 34.5 in the Cushing group and 29.5 in the NFPA group. Average tumor size was 5.7 mm in the Cushing group and 21.3 mm in the NFPA group.

Before surgery, 2.9% of patients with Cushing disease and 15.4% of patients with NFPA had central hypothyroidism, and 8% in the Cushing group and 56.8% in the NFPA group had hyperprolactinemia. Central adrenal insufficiency occurred in 11% with NFPA and in all with Cushing disease, by definition.

After surgery, 93.8% in the Cushing group and 16.5% in the NFPA group had adrenal insufficiency. In addition, patients with Cushing disease had lower postsurgical nadir serum cortisol levels (63.8 nmol/L) than those with NFPA (282.3 nmol/L).

Of the 17 patients with Cushing disease — all women — who developed autoimmune disease within 3 years, 6 had a personal history of autoimmune disease and 7 had a family history of it. In addition, 41.2% of them had adrenal insufficiency when they developed the new autoimmune disease. Among the diseases were six autoimmune thyroiditis cases, three Sjögren syndrome cases, and two autoimmune seronegative spondyloarthropathy.

Dr. Heaney said he found it interesting that more than half of the new autoimmune diseases in patients with Cushing disease were related to the thyroid. “In this kind of setting, where you have a patient who has been producing too much steroid over a period of time and then you take that away, it’s almost like you release a brake on the TSH [thyroid-stimulating hormone],” Dr. Heaney said. “So, there’s probably some rebound in TSH that occurs, and that could be driving the thyroiditis, to some extent, that we see in these patients.”

Only one patient with NFPA developed new-onset autoimmune disease, a woman who developed Graves disease 22 months after surgery. When the researchers excluded patients in both groups with central hypothyroidism, new-onset autoimmune disease was still significantly higher (11.4%) in the Cushing group than in the NFPA group (1.9%; HR, 7.02; 95% CI, 2.54-19.39).
 

Could Postoperative Adrenal Insufficiency Contribute to Risk?

Within the Cushing cohort, those who developed autoimmune disease had a lower BMI (31.8 vs 34.8) and larger tumor size (7.2 vs 5.6 mm) than those who didn’t develop new autoimmune disease. Patients who developed autoimmune disease also had a lower baseline urine free cortisol ratio (2.7 vs 6.3) before surgery and more family history of autoimmune disease (41.2% vs 20.9%) than those who didn’t develop one.

“The higher prevalence of adrenal insufficiency and the lower nadir serum cortisol levels in the Cushing disease group suggest that the postoperative adrenal insufficiency in the Cushing disease group might have contributed to autoimmune disease pathogenesis,” the authors wrote. “This finding is clinically significant because cortisol plays a pivotal role in modulating the immune system.”

Most postoperative management among patients with Cushing disease was similar, with all but one patient receiving 0.5 or 1 mg daily dexamethasone within the first week after surgery. (The one outlier received 5 mg daily prednisone.) However, fewer patients who developed autoimmune disease (17.6%) received supraphysiologic doses of glucocorticoid — equivalent to at least 25 mg hydrocortisone — compared with patients who didn’t develop autoimmune disease (41.8%).

“Although the daily average hydrocortisone equivalent replacement doses within the first month and during long-term follow-up were within the physiologic range in both subgroups, patients with Cushing disease who had autoimmune disease received slightly lower doses of glucocorticoid replacement within the first month after surgery,” the authors reported. “The immediate postoperative period might be a critical window where supraphysiologic glucocorticoids seem to be protective with regard to development of autoimmune disease,” they wrote, though they acknowledged the study’s retrospective design as a limitation in drawing that conclusion.

At the least, they suggested that new symptoms in patients with Cushing disease, particularly those with a family history of autoimmune disease, should prompt investigation of potential autoimmune disease.

Recordati Rare Diseases funded the study. The research was also conducted with support from Harvard Catalyst (the Harvard Clinical and Translational Science Center) as well as financial contributions from Harvard University and its affiliated academic healthcare centers. One author reported holding stocks in Pfizer and Amgen, and another reported receiving consulting fees from Corcept. Dr. Heaney reported receiving institutional grants for trials from Corcept, Ascendis, Crinetics, and Sparrow Pharm; serving on the advisory board for Xeris, Recordati, Corcept, Novo Nordisk, Lundbeck, and Crinetics; and serving as a speaker for Chiesi, Novo Nordisk, and Corcept.

TOPLINE:

Age older than 65 years and serum creatinine greater than 140 micromol/L at the time of systemic polyarteritis nodosa (PAN) diagnosis were significant predictors of mortality.

METHODOLOGY:

• A total of 358 patients diagnosed with PAN between 1990 and 2020 were identified from retrospective chart reviews and prospective cohorts from nine countries as a part of GLOBAL-PAN, a collaboration of the European Vasculitis Society, the Vasculitis Clinical Research Consortium, and other networks.
• The goal of the retrospective chart review was to characterize the nature, presentation, and survival rates of patients with PAN.
• The study population included 174 female and 184 male patients; 282 had systemic PAN (sPAN) and 76 had cutaneous PAN (cPAN); the mean age at diagnosis was 44.3 years.

TAKEAWAY:

• Overall survival rates at 1, 5, and 10 years for patients with sPAN were 97.1%, 94.0%, and 89.0%, respectively.
• Significant independent predictors of mortality were age ≥ 65 years at the time of sPAN diagnosis (hazard ratio [HR], 3.85), serum creatinine > 140 micromol/L at the time of diagnosis (HR, 4.93), gastrointestinal involvement (HR, 3.51), and central nervous system involvement (HR, 3.56).
• Constitutional symptoms were significantly more common in patients with sPAN vs cPAN (78.8% vs 44.7%), while patients with cPAN were significantly more likely to be female and have more skin nodules than patients with sPAN.
• Relapse over a median disease duration of 59.6 months was slightly higher for cPAN vs sPAN (38.8% vs 32.1%).

IN PRACTICE:

“This study helps better define the demographic and clinical characteristics of patients with PAN and differentiates sPAN from cPAN,” the researchers wrote.

SOURCE:

The lead author of the study was Omer Karadag, MD, of Hacettepe University, Ankara, Turkey. The study was published online on February 12 in Arthritis & Rheumatology.

LIMITATIONS:

Study limitations included the combination of prospective and retrospective data, varying approaches to patient assessment, and lack of data on treatment effects.

DISCLOSURES:

The study was supported by the Vasculitis Clinical Research Consortium, which received funding from the National Center for Advancing Translational Science, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, and the National Center for Research Resources. Dr. Karadag disclosed research grants from AbbVie, Novartis, Viela-Bio, and TR-Pharma, and consulting fees from AbbVie, Abdi Ibrahim, Celltrion, Novartis, Pfizer, Sandoz, and UCB.

TOPLINE:

Age older than 65 years and serum creatinine greater than 140 micromol/L at the time of systemic polyarteritis nodosa (PAN) diagnosis were significant predictors of mortality.

METHODOLOGY:

• A total of 358 patients diagnosed with PAN between 1990 and 2020 were identified from retrospective chart reviews and prospective cohorts from nine countries as a part of GLOBAL-PAN, a collaboration of the European Vasculitis Society, the Vasculitis Clinical Research Consortium, and other networks.
• The goal of the retrospective chart review was to characterize the nature, presentation, and survival rates of patients with PAN.
• The study population included 174 female and 184 male patients; 282 had systemic PAN (sPAN) and 76 had cutaneous PAN (cPAN); the mean age at diagnosis was 44.3 years.

TAKEAWAY:

• Overall survival rates at 1, 5, and 10 years for patients with sPAN were 97.1%, 94.0%, and 89.0%, respectively.
• Significant independent predictors of mortality were age ≥ 65 years at the time of sPAN diagnosis (hazard ratio [HR], 3.85), serum creatinine > 140 micromol/L at the time of diagnosis (HR, 4.93), gastrointestinal involvement (HR, 3.51), and central nervous system involvement (HR, 3.56).
• Constitutional symptoms were significantly more common in patients with sPAN vs cPAN (78.8% vs 44.7%), while patients with cPAN were significantly more likely to be female and have more skin nodules than patients with sPAN.
• Relapse over a median disease duration of 59.6 months was slightly higher for cPAN vs sPAN (38.8% vs 32.1%).

IN PRACTICE:

“This study helps better define the demographic and clinical characteristics of patients with PAN and differentiates sPAN from cPAN,” the researchers wrote.

Patients with recalcitrant hidradenitis suppurativa (HS) who self-administered intravenous ertapenem for an average of 13 weeks experienced improvements in clinical and inflammatory markers, and expressed satisfaction at the completion of treatment, a retrospective study showed.

“These findings suggest a course of 12 to 16 weeks of ertapenem may be appropriate as a new standard length of therapy in HS patients, which is at least twice the current recommendation of the North American treatment guidelines,” wrote corresponding author Steven R. Cohen, MD, MPH, of the departments of dermatology at Weill Cornell Medicine and Albert Einstein College of Medicine, New York, and his coauthors. The results were published online February 14, 2024, in JAMA Dermatology.

In an earlier study , some of the same researchers evaluated the efficacy of daily IV ertapenem for 6 weeks in seven patients with HS. The patients experienced “notable remediation of disease that was rapidly lost within 1 month of withdrawal.”

Key outcome measures of interest were the HS Physician Global Assessment (PGA) score (a 6-point scale ranging from clear to very severe) and a numerical rating scale (NRS) for pain (an 11-point scale in which a score of 0 indicates no pain and a score of 10 indicates the worst possible pain) and markers of inflammation such as leukocytes, erythrocyte sedimentation rate, C-reactive protein (CRP), and interleukin (IL)-6. The researchers measured these outcomes at baseline, the midcourse of IV ertapenem treatment, at the end of the course, and post therapy.

The mean age of the patients was 35.8 years, 62.2% were female, and 60.2% were Black. The mean treatment duration was 13.1 weeks and the mean posttherapy follow-up occurred after a mean of 7.8 weeks.

Between baseline and posttherapy follow-up, the HS PGA scores dropped from a mean of 3.9 to 2.7 and the NRS for pain dropped from 4.2 to 1.8 (P < .001 for both associations). Markers of inflammation also dropped between baseline and post therapy.

Specifically, values for CRP dropped from 5.4 to 2.4 mg/dL; IL-6 dropped from 25.2 to 13.7, and leukocytes dropped from 11.3 to 10.0 (P < .001 for all associations). Among the 76 patients who participated in a follow-up telephone survey, 63 (80.3%) reported medium to high satisfaction with their course of ertapenem, and 69 (90.8%) said they would recommend the treatment to other patients with HS.

The authors noted certain limitations of their study, including its retrospective, single-center design, the lack of a control group, and the fact that the HS-PGA scores at each visit did not meet the threshold of a 2-point decrease that is considered a clinically meaningful in the medical literature.

The definitive mechanism of ertapenem efficacy remains elusive, the authors pointed out. “Although oral antibiotics are generally accepted as a core therapeutic approach to HS, much less is known about the efficacy of IV antibiotics, especially ertapenem, a parenteral carbapenem possessing activity against many gram-positive bacteria, gram-negative bacteria, and anaerobic organisms,” they wrote.

In an accompanying editorial, Haley B. Naik, MD, MHSc, a dermatologist at the University of California, San Francisco, said that adopting prolonged courses of ertapenem treatment “comes with substantial individual and public health considerations”.

“Even though HS is a noninfectious disease, microbes might play a role in inciting HS immune dysregulation, prompting the inclusion of antimicrobial therapy in treatment regimens. However, broad-spectrum antibiotics for HS are associated with high levels of antibiotic resistance,” she wrote. Prolonged use of ertapenem and other carbapenems in HS treatment “will likely increase antimicrobial resistance, thereby limiting management of both HS and comorbid infections.”

Jennifer L. Hsiao, MD, a dermatologist who directs the HS clinic at the University of Southern California, Los Angeles, who was asked to comment on the study, said that, despite significant advances in the management of HS over the past decade, there are still patients who do not respond adequately to standard treatments.

For these patients, IV ertapenem can serve as a valuable bridge to a longer-term therapeutic option, “be it surgery or escalated immunomodulation,” such as dual biologic therapy, she said. “In my personal experience, IV ertapenem, which like the authors I also typically use for a 12-week course, delivers impressive and fast results even in the worst disease cases.

“It can be difficult to maintain the therapeutic benefit of ertapenem after it is discontinued, which is why patients should be on concomitant medications as they were in this study and have a post-ertapenem treatment plan in place,” said Dr. Hsiao, who was not involved with the study. “Hopefully, we will be able to one day understand why ertapenem is so effective for HS and be able to harness that benefit for patients without concern for antimicrobial resistance.”

Poor communication between physician and patient can cause a lot of harm, according to Joseph N. Cappella, PhD, Gerald R. Miller Professor Emeritus of Communication at the University of Pennsylvania in Philadelphia, and Richard N. Street Jr, PhD, professor of communication and media science at Texas A&M University in Houston, Texas. When a physician and patient talk past each other, it may impair the patient’s compliance with preventive measures, screening, and treatment; undermine the physician-patient relationship; exacerbate fears and concerns; and possibly lead patients to rely on misleading, incomplete, or simply incorrect information, turning away from evidence-based medicine.

Drs. Cappella and Street made these points in an essay recently published in JAMA. The essay marks the beginning of the JAMA series Communicating Medicine.

“Helping clinicians deliver accurate information more effectively can lead to better-informed patients,” wrote Anne R. Cappola, MD, professor of endocrinology, diabetes, and metabolism at the University of Pennsylvania, and Kirsten Bibbins-Domingo, MD, PhD, professor of medicine at the University of California, San Francisco, in an accompanying editorial. Drs. Cappola and Bibbins-Domingo also are editors of JAMA.

To establish a common understanding between physician and patient, Drs. Cappella and Street identified the following four responsibilities of the physician:

• Discover what the patient understands and why
• Provide accurate information in an understandable manner
• Promote the credibility of the information
• Verify whether the patient has understood.

“Research has shown that although medical facts need to be the basis for the clinician’s core message, those facts are more effectively communicated in a patient-clinician relationship characterized by trust and cooperation and when the information is presented in a manner that fosters patient understanding,” wrote Drs. Cappella and Street. This approach includes using interpreters for patients who do not fluently speak the physician’s language and supplementing explanations with simple written information, images, and videos.

Patients generally believe their physician’s information, and most patients view their physicians as a trustworthy source. Trust is based on the belief that the physician has the patient’s best interests at heart.

However, patients may be distrustful of their physician’s information if it contradicts their own belief system or personal experiences or because they inherently distrust the medical profession.

In addition, patients are less willing to accept explanations and recommendations if they feel misunderstood, judged, discriminated against, or rushed by the physician. The basis for effective communication is a relationship with patients that is built on trust and respect. Empirically supported strategies for expressing respect and building trust include the following:

• Affirming the patient’s values
• Anticipating and addressing false or misleading information
• Using simple, jargon-free language
• Embedding facts into a story, rather than presenting the scientific evidence dryly.

“Conveying factual material using these techniques makes facts more engaging and memorable,” wrote Drs. Cappella and Street. It is crucial to inquire about and consider the patient’s perspective, health beliefs, assumptions, concerns, needs, and stories in the conversation.

This article was originally published on February 10 in Eric Topol’s substack “Ground Truths.”

It’s astounding how devious cancer cells and tumor tissue can be. This week in Science we learned how certain lung cancer cells can function like “Catch Me If You Can” — changing their driver mutation and cell identity to escape targeted therapy. This histologic transformation, as seen in an experimental model, is just one of so many cancer tricks that we are learning about.

Recently, as shown by single-cell sequencing, cancer cells can steal the mitochondria from T cells, a double whammy that turbocharges cancer cells with the hijacked fuel supply and, at the same time, dismantles the immune response.

Last week, we saw how tumor cells can release a virus-like protein that unleashes a vicious autoimmune response.

And then there’s the finding that cancer cell spread predominantly is occurring while we sleep.

As I previously reviewed, the ability for cancer cells to hijack neurons and neural circuits is now well established, no less their ability to reprogram neurons to become adrenergic and stimulate tumor progression, and interfere with the immune response. Stay tuned on that for a new Ground Truths podcast with Prof Michelle Monje, a leader in cancer neuroscience, which will post soon.

Add advancing age’s immunosenescence as yet another challenge to the long and growing list of formidable ways that cancer cells, and the tumor microenvironment, evade our immune response.

An Ever-Expanding Armamentarium

All of this is telling us how we need to ramp up our game if we are going to be able to use our immune system to quash a cancer. Fortunately, we have abundant and ever-growing capabilities for doing just that.

Immune Checkpoint Inhibitors

The field of immunotherapies took off with the immune checkpoint inhibitors, first approved by the FDA in 2011, that take the brakes off of T cells, with the programmed death-1 (PD-1), PD-ligand1, and anti-CTLA-4 monoclonal antibodies.

But we’re clearly learning they are not enough to prevail over cancer with common recurrences, only short term success in most patients, with some notable exceptions. Adding other immune response strategies, such as a vaccine, or antibody-drug conjugates, or engineered T cells, are showing improved chances for success.

Therapeutic Cancer Vaccines

There are many therapeutic cancer vaccines in the works, as reviewed in depth here.

Here’s a list of ongoing clinical trials of cancer vaccines. You’ll note most of these are on top of a checkpoint inhibitor and use personalized neoantigens (cancer cell surface proteins) derived from sequencing (whole-exome or whole genome, RNA-sequencing and HLA-profiling) the patient’s tumor.

An example of positive findings is with the combination of an mRNA-nanoparticle vaccine with up to 34 personalized neoantigens and pembrolizumab (Keytruda) vs pembrolizumab alone in advanced melanoma after resection, with improved outcomes at 3-year follow-up, cutting death or relapse rate in half.

Antibody-Drug Conjugates (ADC)

There is considerable excitement about antibody-drug conjugates (ADC) whereby a linker is used to attach a chemotherapy agent to the checkpoint inhibitor antibody, specifically targeting the cancer cell and facilitating entry of the chemotherapy into the cell. Akin to these are bispecific antibodies (BiTEs, binding to a tumor antigen and T cell receptor simultaneously), both of these conjugates acting as “biologic” or “guided” missiles.

A very good example of the potency of an ADC was seen in a “HER2-low” breast cancer randomized trial. The absence or very low expression or amplification of the HER2 receptor is common in breast cancer and successful treatment has been elusive. A randomized trial of an ADC (trastuzumab deruxtecan) compared to physician’s choice therapy demonstrated a marked success for progression-free survival in HER2-low patients, which was characterized as “unheard-of success” by media coverage.

This strategy is being used to target some of the most difficult cancer driver mutations such as TP53 and KRAS.

Oncolytic Viruses

Modifying viruses to infect the tumor and make it more visible to the immune system, potentiating anti-tumor responses, known as oncolytic viruses, have been proposed as a way to rev up the immune response for a long time but without positive Phase 3 clinical trials.

After decades of failure, a recent trial in refractory bladder cancer showed marked success, along with others, summarized here, now providing very encouraging results. It looks like oncolytic viruses are on a comeback path.

Engineering T Cells (Chimeric Antigen Receptor [CAR-T])

As I recently reviewed, there are over 500 ongoing clinical trials to build on the success of the first CAR-T approval for leukemia 7 years ago. I won’t go through that all again here, but to reiterate most of the success to date has been in “liquid” blood (leukemia and lymphoma) cancer tumors. This week in Nature is the discovery of a T cell cancer mutation, a gene fusion CARD11-PIK3R3, from a T cell lymphoma that can potentially be used to augment CAR-T efficacy. It has pronounced and prolonged effects in the experimental model. Instead of 1 million cells needed for treatment, even 20,000 were enough to melt the tumor. This is a noteworthy discovery since CAR-T work to date has largely not exploited such naturally occurring mutations, while instead concentrating on those seen in the patient’s set of key tumor mutations.

As currently conceived, CAR-T, and what is being referred to more broadly as adoptive cell therapies, involves removing T cells from the patient’s body and engineering their activation, then reintroducing them back to the patient. This is laborious, technically difficult, and very expensive. Recently, the idea of achieving all of this via an injection of virus that specifically infects T cells and inserts the genes needed, was advanced by two biotech companies with preclinical results, one in non-human primates.

Gearing up to meet the challenge of solid tumor CAR-T intervention, there’s more work using CRISPR genome editing of T cell receptors. A.I. is increasingly being exploited to process the data from sequencing and identify optimal neoantigens.

Instead of just CAR-T, we’re seeing the emergence of CAR-macrophage and CAR-natural killer (NK) cells strategies, and rapidly expanding potential combinations of all the strategies I’ve mentioned. No less, there’s been maturation of on-off suicide switches programmed in, to limit cytokine release and promote safety of these interventions. Overall, major side effects of immunotherapies are not only cytokine release syndromes, but also include interstitial pneumonitis and neurotoxicity.

Summary

Given the multitude of ways cancer cells and tumor tissue can evade our immune response, durably successful treatment remains a daunting challenge. But the ingenuity of so many different approaches to unleash our immune response, and their combinations, provides considerable hope that we’ll increasingly meet the challenge in the years ahead. We have clearly learned that combining different immunotherapy strategies will be essential for many patients with the most resilient solid tumors.

Of concern, as noted by a recent editorial in The Lancet, entitled “Cancer Research Equity: Innovations For The Many, Not The Few,” is that these individualized, sophisticated strategies are not scalable; they will have limited reach and benefit. The movement towards “off the shelf” CAR-T and inexpensive, orally active checkpoint inhibitors may help mitigate this issue.

Notwithstanding this important concern, we’re seeing an array of diverse and potent immunotherapy strategies that are providing highly encouraging results, engendering more excitement than we’ve seen in this space for some time. These should propel substantial improvements in outcomes for patients in the years ahead. It can’t happen soon enough.

It’s astounding how devious cancer cells and tumor tissue can be. This week in Science we learned how certain lung cancer cells can function like “Catch Me If You Can” — changing their driver mutation and cell identity to escape targeted therapy. This histologic transformation, as seen in an experimental model, is just one of so many cancer tricks that we are learning about.

Recently, as shown by single-cell sequencing, cancer cells can steal the mitochondria from T cells, a double whammy that turbocharges cancer cells with the hijacked fuel supply and, at the same time, dismantles the immune response.

Last week, we saw how tumor cells can release a virus-like protein that unleashes a vicious autoimmune response.

And then there’s the finding that cancer cell spread predominantly is occurring while we sleep.

As I previously reviewed, the ability for cancer cells to hijack neurons and neural circuits is now well established, no less their ability to reprogram neurons to become adrenergic and stimulate tumor progression, and interfere with the immune response. Stay tuned on that for a new Ground Truths podcast with Prof Michelle Monje, a leader in cancer neuroscience, which will post soon.

Add advancing age’s immunosenescence as yet another challenge to the long and growing list of formidable ways that cancer cells, and the tumor microenvironment, evade our immune response.

An Ever-Expanding Armamentarium

All of this is telling us how we need to ramp up our game if we are going to be able to use our immune system to quash a cancer. Fortunately, we have abundant and ever-growing capabilities for doing just that.

Immune Checkpoint Inhibitors

The field of immunotherapies took off with the immune checkpoint inhibitors, first approved by the FDA in 2011, that take the brakes off of T cells, with the programmed death-1 (PD-1), PD-ligand1, and anti-CTLA-4 monoclonal antibodies.

But we’re clearly learning they are not enough to prevail over cancer with common recurrences, only short term success in most patients, with some notable exceptions. Adding other immune response strategies, such as a vaccine, or antibody-drug conjugates, or engineered T cells, are showing improved chances for success.

Therapeutic Cancer Vaccines

There are many therapeutic cancer vaccines in the works, as reviewed in depth here.

Here’s a list of ongoing clinical trials of cancer vaccines. You’ll note most of these are on top of a checkpoint inhibitor and use personalized neoantigens (cancer cell surface proteins) derived from sequencing (whole-exome or whole genome, RNA-sequencing and HLA-profiling) the patient’s tumor.

An example of positive findings is with the combination of an mRNA-nanoparticle vaccine with up to 34 personalized neoantigens and pembrolizumab (Keytruda) vs pembrolizumab alone in advanced melanoma after resection, with improved outcomes at 3-year follow-up, cutting death or relapse rate in half.

Antibody-Drug Conjugates (ADC)

There is considerable excitement about antibody-drug conjugates (ADC) whereby a linker is used to attach a chemotherapy agent to the checkpoint inhibitor antibody, specifically targeting the cancer cell and facilitating entry of the chemotherapy into the cell. Akin to these are bispecific antibodies (BiTEs, binding to a tumor antigen and T cell receptor simultaneously), both of these conjugates acting as “biologic” or “guided” missiles.

A very good example of the potency of an ADC was seen in a “HER2-low” breast cancer randomized trial. The absence or very low expression or amplification of the HER2 receptor is common in breast cancer and successful treatment has been elusive. A randomized trial of an ADC (trastuzumab deruxtecan) compared to physician’s choice therapy demonstrated a marked success for progression-free survival in HER2-low patients, which was characterized as “unheard-of success” by media coverage.

This strategy is being used to target some of the most difficult cancer driver mutations such as TP53 and KRAS.

Oncolytic Viruses

Modifying viruses to infect the tumor and make it more visible to the immune system, potentiating anti-tumor responses, known as oncolytic viruses, have been proposed as a way to rev up the immune response for a long time but without positive Phase 3 clinical trials.

TOPLINE:

Skin conditions burden many children with inflammatory bowel disease (IBD), according to the authors of a single-center study.

METHODOLOGY:

• Little is known about the prevalence of IBD-associated skin lesions and their association with IBD severity in children ages 18 and younger.Researchers retrospectively reviewed the medical charts of 425 children and adolescents with  (CD) or ulcerative  (UC) at one or more dermatologic diagnoses who were seen at Mayo Clinic, Rochester, Minnesota, between 1999 and 2017.
• Of the children studied, 53% were male, 64.9% had CD, and 42.8% had one or more cutaneous infections.
• They used the chi-square/Fischer’s exact test to compare categorical outcomes between patients with CD and UC and to detect differences in IBD/CD/UC disease severity and skin conditions.
• Researchers retrospectively reviewed the medical charts of 425 children and adolescents with Crohn’s disease (CD) or ulcerative colitis (UC) at one or more dermatologic diagnoses who were seen at Mayo Clinic, Rochester, Minnesota, between 1999 and 2017.
• Of the children studied, 53% were male, 64.9% had CD, and 42.8% had one or more cutaneous infections.
• They used the chi-square/Fischer’s exact test to compare categorical outcomes between patients with CD and UC and to detect differences in IBD/CD/UC disease severity and skin conditions.

TAKEAWAY:

• The most common noninfectious dermatologic condition among the 425 children and adolescents was  (30.8%), followed by eczema (15.8%) and perianal skin tags (14.6%).
• Angular cheilitis was more common among those with CD than those with UC (7.2% vs 2%, respectively; P = .024) as was keratosis pilaris (6.9% vs 0.7%; P = .003), and perianal skin complications such as skin tags (20.3% vs 4%), fistulas (13.4% vs 2.7%), and abscesses (13.4% vs 2%; P < .001 for all associations).
• Fungal skin infections were more frequently diagnosed in children with UC than those with CD (15.4% vs 8%; P = .017).
• The researchers observed that the severity of IBD correlated with a higher prevalence of perianal fistula (P = .003), perianal region abscess (P = .041), psoriasis (P < .001), and pyoderma gangrenosum (P = .003).

IN PRACTICE:

“Early identification of common dermatologic conditions in children and adolescents with IBD and recognizing their characteristic associations may alter management and improve skin-related outcomes in this patient population,” the authors wrote.

SOURCE:

Corresponding author Megha M. Tollefson, MD, of the Department of Dermatology at Mayo Clinic, Rochester, Minnesota, and colleagues conducted the research, which was published in Pediatric Dermatology.

LIMITATIONS:

The single-center design and the fact that database studies are subject to extraction error. There was no age- and sex-matched cohort to determine whether the prevalence of cutaneous infections, acne, eczema, and other inflammatory disorders was truly increased in IBD.

DISCLOSURES:

The researchers reported having no disclosures.

On February 14, 2024, Galderma announced that the Food and Drug Administration (FDA) has accepted its Biologics License Application (BLA) for nemolizumab for the treatment of patients with prurigo nodularis and for adolescents and adults with moderate to severe atopic dermatitis.

A first-in-class investigational monoclonal antibody specifically designed to inhibit interleukin (IL) IL-31 signaling, nemolizumab has also been granted FDA Priority Review for prurigo nodularis, according to a press release from the company. The European Medicines Agency has also accepted Galderma’s Marketing Authorization Applications for nemolizumab for both prurigo nodularis and atopic dermatitis.

The regulatory developments follow data from the phase III OLYMPIA clinical trial program, which evaluated the efficacy and safety of nemolizumab administered subcutaneously every 4 weeks in patients with prurigo nodularis (NCT04501679 and NCT04501666). According to the press release, in OLYMPIA 1 and 2, 58% and 56% of patients, respectively, achieved at least a least four-point reduction in itch intensity as measured by the peak-pruritus numerical rating scale (PP-NRS), compared with 17% and 21% in the placebo groups (P < .0001). At the same time, 26% and 38% of nemolizumab-treated patients reached clearance or almost-clearance of skin lesions on the investigator’s global assessment (IGA) score, compared with 7% and 11% in the placebo groups (P < .0001).

According to the press release, in OLYMPIA 1 and 2, 58% and 56% of patients, respectively, achieved at least a least four-point reduction in itch intensity as measured by the peak-pruritus numerical rating scale (PP-NRS), compared with 17% and 21% in the placebo groups (P < .0001). At the same time, 26% and 38% of nemolizumab-treated patients reached clearance or almost-clearance of skin lesions on the investigator’s global assessment (IGA) score, compared with 7% and 11% in the placebo groups (P < .0001).
