VIENNA — Results from the phase 3 SELECT-GCA study showed that the Janus kinase (JAK) inhibitor upadacitinib (Rinvoq) induces significant and sustained remission in people with new-onset or relapsing giant cell arteritis (GCA).

The primary endpoint of sustained remission — the absence of GCA signs or symptoms from weeks 12 to 52 together with adherence to a steroid-tapering regimen — occurred in 46% of 210 individuals randomly assigned to treatment treated with a once-daily 15-mg dose of upadacitinib and 29% of 105 randomly assigned to placebo (P = .0019).

Nine of the 11 secondary endpoints were also positive for upadacitinib 15 mg vs placebo, and no new safety concerns were identified in a late-breaking abstract presented at the at the annual European Congress of Rheumatology.
 

First JAK Trial in GCA

This is the first trial to look at the use of a JAK inhibitor for the treatment of GCA, and it is addressing a real unmet need, the presenting study investigator Daniel Blockmans, MD, PhD, of University Hospitals Leuven in Belgium, told this news organization.

Glucocorticoids remain the mainstay of treatment, and tocilizumab has been licensed for use, but people don’t always get better or can relapse, he explained.

“I have the impression that these only suppress the disease but do not cure it,” Dr. Blockmans said, adding that “patients get very well soon after these treatments are started, but there are more and more reports that there is a kind of smoldering vasculitis that exists, and this can lead to dilatation of the aorta.”

Upadacitinib inhibits two JAK-dependent cytokines, interleukin 6 and interferon gamma, which have been implicated in the pathogenesis of GCA. The latter could be particularly important, Dr. Blockmans suggested.
 

Study Details

SELECT-GCA is an ongoing multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of upadacitinib vs placebo in patients with GCA.

A total of 428 patients have been included: 210 were randomly allocated to treatment with upadacitinib 15 mg, 105 to upadacitinib 7.5 mg, and 105 to placebo. The inclusion of the lower “minimally effective” upadacitinib dose was a requirement of the regulatory authorities, Dr. Blockmans said; the licensed dose in rheumatoid arthritis (RA) is 15 mg.

Dr. Blockmans reported data from the first 52 weeks of the trial during which all patients underwent glucocorticoid tapering — 26 weeks for upadacitinib and 52 weeks for placebo.

No imaging was done in this trial, which Dr. Blockmans said should be considered for future studies.
 

Secondary Endpoints

One of the key secondary endpoints was sustained complete remission, defined as sustained remission plus a normalized erythrocyte sedimentation rate to ≤ 30 mm/h and reducing high-sensitivity C-reactive protein to < 1 mg/dL.

Sustained complete remission occurred in 37% and 16% of patients treated with upadacitinib 15 mg and placebo, respectively (P < .0001).

Additionally, a significantly lower proportion of upadacitinib 15 mg- than placebo-treated patients experienced at least one disease flare through week 52 (34% vs 56%, P = .0014).

Other positive secondary endpoints for upadacitinib 15 mg vs placebo out to week 52 were the number of disease flares per patient, cumulative glucocorticoid exposure, and complete remission (also at week 24).

And significant changes in SF-36 and FACIT-Fatigue from baseline to week 52 were seen for upadacitinib 15 mg.

The only secondary endpoints not showing a clear benefit for upadacitinib 15 mg were the changes in the Treatment Satisfaction Questionnaire for Medication at 52 weeks and the rate of glucocorticoid-related adverse events through week 52.

As for the 7.5-mg dose of upadacitinib, neither the primary nor secondary endpoints were significantly better vs placebo.
 

 

 

‘Life-Changing’

The study’s findings could be “really life-changing” for patients with this type of vasculitis if upadacitinib gets approval for use in this indication, Milena Bond, MD, PhD, of Brunico Hospital in Italy, told this news organization at the meeting.

“Unfortunately, nowadays, we still have only a few options for treating these patients,” she said. “So, this drug could be really, really important.”

Dr. Bond added: “The data ... also shows there is a very good safety profile, which was a main concern given the class of the drug. So, I’m very positive about this treatment and very excited to see the preliminary results.”

After his presentation, Dr. Blockmans said, “Of course, if we already had an ideal treatment for GCA, there would be no need for a JAK inhibitor, but I don’t think that steroid treatment or tocilizumab treatment is the ideal treatment.”
 

Judicious Use Still Warranted

Upadacitinib still needs to be used cautiously, following appropriate guidance from the European Medicines Agency (EMA) and the US Food and Drug Administration.

Dr. Bond said: “It is not advised to use to the drug when people are older than 65 years old,” according to the EMA, for example, and “given the rules that we have, I would not use this drug as a first-line treatment. We do not do that for rheumatoid arthritis.”

But, she added, “As for arthritis, when you fail treating patients with the other alternatives, you could use this drug, and you have to discuss risks with the patients.”

Dr. Blockmans reported there had been no increased risk for major adverse cardiovascular events or venous thromboembolism associated with upadacitinib relative to placebo in the population of patients studied, and he pointed out that they had a much higher risk for these events than perhaps an RA population.

He said: “It’s effective, and it’s apparently safe in these older people, despite what we heard about tofacitinib in the ORAL [Surveillance] study; we didn’t see these problems here in this elderly population.”

The SELECT-GCA trial was funded by AbbVie, and the company participated in all aspects of the study, including its design, conduct, interpretation of data, and reporting. Dr. Blockmans received no funding or other honoraria from the company but reported a research grant from Roche and consulting fees from GlaxoSmithKline. Most of his coauthors reported financial relationships with AbbVie, and some are employees of the company. Dr. Bond reported no relevant financial relationships.

Prospective MS Trial Proves Ocrelizumab Efficacy in Under-Represented Populations

In a population of Black/African American and Hispanic/Latino patients with multiple sclerosis (MS), ocrelizumab had high efficacy and an acceptable safety profile, according to the results of a 1-year analysis of the CHIMES trial. The study is the first-ever prospective study of an MS disease-modifying therapy (DMT) exclusively performed in under-represented populations, and offers lessons to researchers aiming to design more inclusive clinical trials to bolster participation by under-represented populations.

“The goal was to better understand efficacy of therapy in under-represented populations because we typically have very low numbers of these patients in our clinical trials, although there are multiple studies over the past decades suggesting that there may be poorer outcomes in Black and Hispanic individuals, particularly in the United States, and that there also may be more aggressive disease,” said Mitzi Williams, MD, who presented the study in a poster session at the annual meeting of the Consortium of Multiple Sclerosis Centers.

The team recruited 113 Black participants and 69 Hispanic participants, and, in fact, over-recruited the target number by 25%, and did so 2 months before the launch of the study in July 2020, which just happened to be in the midst of a global pandemic.

After 48 weeks of ocrelizumab treatment, 46.0% of Black participants and 58.0% of Hispanic participants achieved no evidence of disease activity in three components (NEDA-3), while 94.7% and 95.7% were free from relapses, respectively, and 94.7% and 94.2% were free from disease worsening. Serious adverse events occurred in 6.2% and 4.3% of each group, respectively, and there were no new safety signals in either group.

“The good news is that the efficacy and safety was very similar to what we saw in other clinical trials. I don’t think we really expected it to be much different, because when we think about race, it’s a social construct, not a biologic construct. What we do hope to find out is more about some of the interplay of social determinants of health, and how getting on high efficacy treatment can improve and increase productivity and outcomes in the long term,” said Dr. Williams, who is medical director of Joi Life Wellness Group, Smyrna, Georgia.

The researchers succeeded by involving patient advocates and advocacy organizations at the very earliest stages of the trial design. “We were very intentional about looking at things like social determinants of health, childcare, transportation, and things like that to ease some of the burden of participating in the trial, obviously in a legal and compliant way,” said Dr. Williams. The team also ensured complete and accurate translation of patient materials into Spanish.

The study was also a phase 4 trial, which may have simplified recruitment. “So it’s a therapy that’s already approved, which may make people feel more comfortable, but obviously the goal is for our phase 3 trials to make sure that we are recruiting represented populations. We’re taking these learnings and applying them to the broader clinical trial population so that hopefully we won’t have to come back and do phase 4 studies like this,” said Dr. Williams.

She noted that the results of more inclusive studies don’t just benefit underserved populations. “You have groups of people that are suffering and having more disability from a condition, and you need to understand why. When we broaden the population to understand those that are most vulnerable and underserved and [having the worst outcomes], it really helps us to better treat everybody. Because if we can get a hold of those factors that make us do the worst, then we can also better understand the factors that make us do the best,” said Dr. Williams.
 

 

 

Inclusive Recruitment in Clinical Trials

Asked for comment, Ahmed Obeidat, MD, PhD, highlighted the importance of inclusive recruitment. “The study is very important because historically and even in most recent clinical trials, these groups were markedly under-represented and most completed clinical trials derive conclusions based on the study of a nondiverse, White-non-Hispanic predominant population,” said Dr. Obeidat, who is an associate professor at the Medical College of Wisconsin, Milwaukee. He pointed to a systematic review showing that the median percentage of White participants in MS clinical trials was 93% and ranged from 86% to 98%.

“Several factors may contribute to the disparity in clinical trial participation, and solutions must be explored and developed. CHIMES is a first step in this direction where the study itself is designed to address disparity in MS clinical trial participation,” said Dr. Obeidat.

Dr. Obeidat also pointed to the need to consider other forms of diversity in clinical trials, such as older patients and those with advanced disability. “Investigators, coordinators, and other staff should all strive to be as inclusive as possible in clinical trials,” he said.

Dr. Williams has received consulting fees from Alexion, Biogen, Bristol Myers Squibb, EMD Serono, Genentech Inc., Janssen, Novartis, Sanofi, and TG Therapeutics, and serves on speakers bureaus for Biogen, Bristol Myers Squibb, EMD Serono, Janssen, Genentech, and TG Therapeutics. Dr. Ahmed Z. Obeidat has financial relationships with Alexion Pharmaceuticals, Banner Life Sciences, BD Biosciences, Biogen, Biologix Solutions, Bristol Myers Squibb, Celgene, EMD Serono, Genentech, GW Pharmaceuticals, Horizon Therapeutics, Jazz Pharmaceuticals, Novartis, Sandoz, Sanofi Genzyme, TG Therapeutics, and Viela Bio.

She noted that the results of more inclusive studies don’t just benefit underserved populations. “You have groups of people that are suffering and having more disability from a condition, and you need to understand why. When we broaden the population to understand those that are most vulnerable and underserved and [having the worst outcomes], it really helps us to better treat everybody. Because if we can get a hold of those factors that make us do the worst, then we can also better understand the factors that make us do the best,” said Dr. Williams.
 

 

 

Inclusive Recruitment in Clinical Trials

Asked for comment, Ahmed Obeidat, MD, PhD, highlighted the importance of inclusive recruitment. “The study is very important because historically and even in most recent clinical trials, these groups were markedly under-represented and most completed clinical trials derive conclusions based on the study of a nondiverse, White-non-Hispanic predominant population,” said Dr. Obeidat, who is an associate professor at the Medical College of Wisconsin, Milwaukee. He pointed to a systematic review showing that the median percentage of White participants in MS clinical trials was 93% and ranged from 86% to 98%.

“Several factors may contribute to the disparity in clinical trial participation, and solutions must be explored and developed. CHIMES is a first step in this direction where the study itself is designed to address disparity in MS clinical trial participation,” said Dr. Obeidat.

Dr. Obeidat also pointed to the need to consider other forms of diversity in clinical trials, such as older patients and those with advanced disability. “Investigators, coordinators, and other staff should all strive to be as inclusive as possible in clinical trials,” he said.

Quitting Anabolic Steroids Can Still Impair Men Afterward

Article Type

Tue, 06/18/2024 - 15:06

BOSTON — Men who stop using performance-enhancing anabolic-androgenic steroids (AAS) experience significant depression, anxiety, and diminished sexual function within the first year after quitting, new research found.

The data suggest that monitoring these men and, pending clinical trial evidence, intervening to minimize these effects could help prevent recidivism, Bonnie Grant, MBBS, a clinical research fellow at Imperial College London, London, England, told this news organization.

“Nothing has actually been studied in proper randomized controlled trials … but I think there’s going to be a role for medicine alongside psychological treatment … Clinicians often see men who have stopped [taking steroids] who report feeling low in mood … a lot of these men will just restart taking them again,” she said.

Anabolic steroids taken exogenously suppress the hypothalamic-pituitary-gonadal system, thereby suppressing endogenous testosterone secretion. While AAS do enhance muscle-building, they can also lead to enlarged hearts, hypertension, and infertility. Most of these are reversible if the man stops taking the AAS.

However, after stopping, the testosterone levels can take up to a year to return to normal. During that time, the man can experience symptoms including low libido, erectile dysfunction, low mood, and fatigue. This leads to a dependence syndrome in about 30%. About 65% of men who stop taking anabolic steroids will restart taking them within the first year, Dr. Grant said in presenting her findings at the annual meeting of the Endocrine Society.

Asked to comment, session moderator Frances Hayes, MBBCh, associate clinical chief of the Division of Reproductive Endocrinology at Massachusetts General Hospital, Boston, said, “One question is, if you intervene with an antidepressant, will that prevent the people from relapsing and going back to using? I think that’s certainly something that would need to be explored and tested.”

Dr. Hayes also noted that fertility problems may lead some men to decide to stop using the steroids. “That can be a strong motivator. If you have a motivated patient, then you add in an antidepressant or anxiolytic or link the patients with mental health services. I think that would definitely be beneficial and definitely something we need to address and see if it is worthwhile doing.”

Dr. Grant presented data from her group’s cross-sectional, observational study. Of a total 245 men, 116 were current AAS users, 84 were previous AAS users who had quit within the past year, and 45 had never used them. All completed extensive questionnaires about their substance use, mood, sexual function, and anxiety. They had morning blood tests, and urine samples were taken for toxicology testing.

The three groups didn’t differ by age (most were in their mid-30s) or ethnicity (most were White). However, the proportion who self-reported psychiatric diagnoses (mostly depression or anxiety) was significantly higher among both the current (29%) and past (25%) AAS users than among the never users (6.6%), with P = .0094.

Dr. Hayes commented, “One of the drawbacks of this study was they didn’t have baseline data. But it would make sense, I think, that the incidence of depression and anxiety was higher in the people who went on to use anabolic steroids.”

Use of other illicit drugs — mostly cocaine and cannabis — was also higher among the past (40.5%) and current (47.4%) AAS users than among the nonusers (17.7%), P = .0025.

Not surprisingly, total testosterone levels were much higher in current AAS users (62.8 nmol/L) than in past users (20.1 nmol/L) and nonusers (20.0 nmol/L), P < .001. Levels of luteinizing hormone (LH), follicle-stimulating hormone, and sex hormone-binding globulin were significantly lower in the current AAS users than in the other two groups, while estradiol levels were significantly higher (all P < .001).

There were no differences in total testosterone between the never users and previous users. However, about 25% of the men who stopped continued to have lower-than-normal testosterone levels, Dr. Grant noted.

Depression scores, as assessed by the Beck Depression Inventory-II, were highest in men who stopped using AAS, and lowest in the never users. Moderate to severe depression was present in 20% of the men who stopped using AAS, 6% of current users, and none of the nonusers.

In multivariable analysis, having a prior psychiatric diagnosis increased the risk for current depression on the Beck inventory by twofold in the current AAS users (P = .001) and threefold in the past users (< .001). “Interestingly, testosterone levels were not associated with depression,” she noted.

Sexual function, as measured by the International Index of Erectile Function (IIEF) 15, was significantly worse among those who had stopped using AAS compared with current users and nonusers (P = .023). At the same time, total testosterone levels were only weakly correlated with IIEF scores.

In multivariate analysis, higher LH levels were associated with worse sexual function (P = .01).

Anxiety, as measured by the General Anxiety Disorder-7 assessment, was higher in previous users than in never users. Overall, 12% of the previous users had moderate or severe anxiety vs just 2% of nonusers.

The next step in the research will be to examine the urine toxicology for AAS and other illicit substances, Dr. Grant said.

“We’re hoping this information will allow for future studies to be developed to design treatments, which will help millions of men worldwide to stop and stay off anabolic steroids,” she concluded.

Dr. Grant and Dr. Hayes had no disclosures.

Pediatric Ocrelizumab Dose Established for MS

Article Type
Changed
Thu, 06/20/2024 - 13:35

In pediatric multiple sclerosis (MS), the optimal dose of ocrelizumab is the same as the 600 mg adult dose for patients weighing more than 35 kg, according to pharmacokinetic/pharmacodynamic (PK/PD) data from the OPERETTA 1 phase 2 clinical trial. The safety profile was similar to adult patients.

“While we believe the disease to be the same in children and adolescents, [MS] is distinguished by its very inflammatory nature, oftentimes causing two to three times the number of relapses per year as their adult-onset colleagues,” said Teri Schreiner, MD, during a presentation of the results at the annual meeting of the Consortium of Multiple Sclerosis Centers.

Approved therapies for pediatric MS include fingolimod in the United States and Europe, as well as dimethyl fumarate in Europe. “There’s a real need for high-efficacy treatment [in pediatric patients], again referring back to this disease being very inflammatory in children and adolescents. We oftentimes will use medications off label but this is clearly suboptimal as we lack safety data, and oftentimes run into difficulty with insurance approval of off-label use of medicine,” said Dr. Schreiner, who is an associate professor of neurology at University of Colorado School of Medicine, Aurora.

To determine the dose in pediatric patients that would produce comparable PK and PD to adults, the researchers dosed six patients aged 10-18 with 300 mg ocrelizumab, and 17 such patients with 600 mg ocrelizumab during a 24-week dose-exploration period, followed by a 264-week optional extension period. The cohorts were separated based on weight of less than or more than 40 kg. The mean ages were 11.2 years (mean weight, 34.9 kg) and 15.3 years (mean weight, 62.3 kg), respectively.

During the dose-exploration period, seven blood draws were performed to characterize PK. “When the PK data was analyzed, we saw that the proper cut-off point was 35 kilos. At less than 35 kilos, the appropriate dose was half of that adult dose, so 300 milligrams every 6 months, whereas above 35 kilos, the proper dose was actually 600, or the adult dose. Given the rarity of pediatric-onset MS patients less than 35 kilos, most patients will benefit from the adult dose of 600 milligrams twice yearly,” said Dr. Schreiner.

PD data were also encouraging. “The primary PD was the absence of CD-19 B cells, and that was tracked over time. While there were a few patients in both cohorts that had modest reconstitution, there was no patient in our study that crossed the retreatment threshold, and all blood samples were negative for anti-drug antibodies,” said Dr. Schreiner.

Adverse events occurred in five of six patients in the 300 mg group (83%; 4 grade 2, 1 grade 3) and 100% of patients in the 600 mg group (1 grade 1, 9 grade 2, 6 grade 3, 1 grade 4). There was one serious adverse event in the 300 mg group (16.7%) and four serious adverse events in the 600 mg group (23.5%). None led to treatment discontinuation. “This is largely consistent with what was seen in the adult studies of ocrelizumab,” said Dr. Schreiner.

Roche is now recruiting for the phase 3 OPERETTA 2 trial, which will use the 600 mg dose and compare outcomes to a fingolimod arm.
 

 

 

Establishing Safety in the Pediatric Population

“In [pediatric onset MS] it’s an important piece of information to design OPERETTA 2 and to dose ocrelizumab in pediatric-onset MS in general,” said Jeffrey A Cohen, MD, professor of neurology at the Cleveland Clinic, who was asked for comment.

During the Q&A period, Dr. Schreiner was asked whether it is possible to extrapolate experience from rituximab to the pediatric population. “They’re very similar molecules, and we know the mechanisms of action, but I think part of the importance of doing these studies is to get the safety data so that we actually can say with certainty, we are giving you a drug that has this list of side effects and we know about them definitively. We all use other high-efficacy medications, but I don’t think we can exactly extrapolate,” said Dr. Schreiner.

Session moderator Amy Perrin Ross, APN, noted the lack of approved pediatric therapies for MS. “This is an extremely important study, because we at least in the lower 48 are quite limited in our resources for approved pediatric cases. Information like this will make it easier for a potential pediatric indication, which would then make it easier on us to go after [treatment of the disease in this population]. The weight-based dosing, I think, is really a good thing. Patients have been asking for weight-based dosing on everything for many years,” she said.

Ahmed Obeidat, MD, PhD, associate professor at the Medical College of Wisconsin, also praised the study. “While pediatric MS is rare, it is an area of unmet need when it comes to disease-modifying therapies as only fingolimod is FDA-approved, and many use B cell–depleting therapy, such as rituximab, off label to treat children with MS with good outcomes. The need for guidance on the dosing of B cell–depleting therapy is a main priority for research in pediatric MS,” he said.

The study was funded by Roche. Dr. Schreiner has consulted for Roche and Cycle Pharmaceuticals. Dr. Cohen has consulted for Astoria, Bristol Myers Squibb, Convelo, EMD Serono Inc, FiND, INMune, and Sandoz. Dr. Obeidat has financial relationships with Alexion Pharmaceuticals, Banner Life Sciences, BD Biosciences, Biogen, Biologix Solutions, Bristol Myers Squibb, Celgene, EMD Serono, Genentech, GW Pharmaceuticals, Horizon Therapeutics, Jazz Pharmaceuticals, Novartis, Sandoz, Sanofi Genzyme, TG Therapeutics, and Viela Bio.

During the dose-exploration period, seven blood draws were performed to characterize PK. “When the PK data was analyzed, we saw that the proper cut-off point was 35 kilos. At less than 35 kilos, the appropriate dose was half of that adult dose, so 300 milligrams every 6 months, whereas above 35 kilos, the proper dose was actually 600, or the adult dose. Given the rarity of pediatric-onset MS patients less than 35 kilos, most patients will benefit from the adult dose of 600 milligrams twice yearly,” said Dr. Schreiner.

PD data were also encouraging. “The primary PD was the absence of CD-19 B cells, and that was tracked over time. While there were a few patients in both cohorts that had modest reconstitution, there was no patient in our study that crossed the retreatment threshold, and all blood samples were negative for anti-drug antibodies,” said Dr. Schreiner.

Adverse events occurred in five of six patients in the 300 mg group (83%; 4 grade 2, 1 grade 3) and 100% of patients in the 600 mg group (1 grade 1, 9 grade 2, 6 grade 3, 1 grade 4). There was one serious adverse event in the 300 mg group (16.7%) and four serious adverse events in the 600 mg group (23.5%). None led to treatment discontinuation. “This is largely consistent with what was seen in the adult studies of ocrelizumab,” said Dr. Schreiner.

Roche is now recruiting for the phase 3 OPERETTA 2 trial, which will use the 600 mg dose and compare outcomes to a fingolimod arm.
 

 

 

Establishing Safety in the Pediatric Population

“In [pediatric onset MS] it’s an important piece of information to design OPERETTA 2 and to dose ocrelizumab in pediatric-onset MS in general,” said Jeffrey A Cohen, MD, professor of neurology at the Cleveland Clinic, who was asked for comment.

During the Q&A period, Dr. Schreiner was asked whether it is possible to extrapolate experience from rituximab to the pediatric population. “They’re very similar molecules, and we know the mechanisms of action, but I think part of the importance of doing these studies is to get the safety data so that we actually can say with certainty, we are giving you a drug that has this list of side effects and we know about them definitively. We all use other high-efficacy medications, but I don’t think we can exactly extrapolate,” said Dr. Schreiner.

Session moderator Amy Perrin Ross, APN, noted the lack of approved pediatric therapies for MS. “This is an extremely important study, because we at least in the lower 48 are quite limited in our resources for approved pediatric cases. Information like this will make it easier for a potential pediatric indication, which would then make it easier on us to go after [treatment of the disease in this population]. The weight-based dosing, I think, is really a good thing. Patients have been asking for weight-based dosing on everything for many years,” she said.

Ahmed Obeidat, MD, PhD, associate professor at the Medical College of Wisconsin, also praised the study. “While pediatric MS is rare, it is an area of unmet need when it comes to disease-modifying therapies as only fingolimod is FDA-approved, and many use B cell–depleting therapy, such as rituximab, off label to treat children with MS with good outcomes. The need for guidance on the dosing of B cell–depleting therapy is a main priority for research in pediatric MS,” he said.

The study was funded by Roche. Dr. Schreiner has consulted for Roche and Cycle Pharmaceuticals. Dr. Cohen has consulted for Astoria, Bristol Myers Squibb, Convelo, EMD Serono Inc, FiND, INMune, and Sandoz. Dr. Obeidat has financial relationships with Alexion Pharmaceuticals, Banner Life Sciences, BD Biosciences, Biogen, Biologix Solutions, Bristol Myers Squibb, Celgene, EMD Serono, Genentech, GW Pharmaceuticals, Horizon Therapeutics, Jazz Pharmaceuticals, Novartis, Sandoz, Sanofi Genzyme, TG Therapeutics, and Viela Bio. Ms. Ross has consulted for EMD Serono, BMS, Horizon, Alexion, TG Therapeutics, Novartis, Roche, and Sanofi.

Ovarian Cancer Risk Doubled by Estrogen-Only HRT

Article Type

Mon, 06/17/2024 - 15:09

Two decades after the landmark Women’s Health Initiative (WHI) changed the way clinicians thought about hormone therapy and cancer, new findings suggest this national health study is "the gift that keeps on giving."

Follow-up from two of the WHI’s randomized trials have found that estrogen alone in women with prior hysterectomy significantly increased ovarian cancer incidence and mortality in postmenopausal women. Estrogen and progesterone together, meanwhile, did not increase ovarian cancer risk, and significantly reduced the risk of endometrial cancer. Rowan T. Chlebowski, MD, PhD, of The Lundquist Institute in Torrance, California, presented these results from the latest WHI findings, at the annual meeting of the American Society of Clinical Oncology in Chicago.

Dr. Chlebowski and his colleagues conducted an analysis from two randomized, placebo-controlled trials, which between 1993 and 1998 enrolled nearly 28,000 postmenopausal women aged 50-79 years without prior cancer from 40 centers across the United States. (The full WHI effort involved a total cohort of 161,000 patients, and included an observational study and two other non-drug trials.)

In one of the hormone therapy trials, 17,000 women with a uterus at baseline were randomized to combined equine estrogen plus medroxyprogesterone acetate, or placebo. In the other trial, about 11,000 women with prior hysterectomy were randomized to daily estrogen alone or placebo. Both trials were stopped early: the estrogen-only trial due to an increased stroke risk, and the combined therapy trial due to findings of increased breast cancer and cardiovascular risk.

Mean exposure to hormone therapy was 5.6 years for the combined therapy trial and 7.2 years for estrogen alone trial.
 

Ovarian Cancer Incidence Doubles with Estrogen

At 20 years’ follow up, with mortality information available for nearly the full cohort, Dr. Chlebowski and his colleagues could determine that ovarian cancer incidence doubled among women who had taken estrogen alone (hazard ratio = 2.04; 95% CI 1.14-3.65; P = .01), a difference that reached statistical significance at 12 years’ follow up. Ovarian cancer mortality was also significantly increased (HR = 2.79 95% CI 1.30-5.99, P = .006). Absolute numbers were small, however, with 35 cases of ovarian cancer compared with 17 in the placebo group.

Combined therapy recipients saw no increased risk for ovarian cancer and significantly lower endometrial cancer incidence (106 cases vs. 140 HR = 0.72; 95% CI, 0.56-0.92; P = .01).

Conjugated equine estrogen, Dr. Chlebowski said during his presentation at the meeting, “was introduced in US clinical practice in 1943 and used for over half a century, yet the question about hormone therapy’s influence on endometrial and ovarian cancer remains unsettled. Endometrial cancer and ovarian cancer are the fourth and fifth leading causes of cancer deaths in women ... and there’s some discordant findings from observational studies.”

Care of Ovarian Cancer Survivors Should Change

The new findings should prompt practice and guideline changes regarding the use of estrogen alone in ovarian cancer survivors, Dr. Chlebowski said.

In an interview, oncologist Eleonora Teplinsky, MD, of Valley-Mount Sinai Comprehensive Cancer Care in Paramus, New Jersey, said that apart from this subgroup of ovarian cancer survivors, the findings would not likely have much impact on how clinicians and patients approach hormone replacement therapy today.

“Twenty years ago the Women’s Health Initiative showed that hormone replacement therapy increases breast cancer risk, and everyone stopped taking HRT. And now people pushing back on it and saying wait a second – it was the estrogen plus progesterone that increased breast cancer, not estrogen alone. And now we’ve got these newer [estrogen] formulations.

“Yes, there’s a little bit of an increased risk [for ovarian cancer]. Patients should be aware. They should know the symptoms of ovarian cancer. But if they have indications and have been recommended HRT, this is not something that we would advise them against because of this very slightly increased risk,” Dr. Teplinsky said.

Oncologist Allison Kurian, MD of Stanford University in Stanford, California, who specializes in breast cancer, also noted that the duration of hormone treatment, treatment timing relative to age of menopause onset, and commonly used estrogen preparations had indeed changed since the time the WHI trials were conducted, making it harder to generalize the findings to current practice. Nonetheless, she argued, they still have real significance.

WHI is an incredibly complex but also incredibly valuable resource,” said Dr. Kurian, who has conducted studies using WHI data. “The first big results came out in 2002, and we’re still learning from it. These are randomized trials, which offer the strongest form of scientific evidence that exists. So whenever we see results from this study, we have to take note of them,” she said.

Because the WHI trials had shown combined therapy, not estrogen alone, to be associated with breast cancer risk, clinicians have felt reassured over the years about using estrogen alone.

“You can’t give it to a person unless they have their uterus removed, because we know it will cause uterine cancer if the uterus is in place. But if the uterus is removed, the feeling was that you can give estrogen alone. I think the new piece that is going to get everyone’s attention is this signal for ovarian cancer.”

Something else the new findings show, Dr. Kurian said, is that WHI is “the gift that keeps on giving,” even after decades. “Some of the participants had a relatively short-term exposure to HRT. They took a medication for just a little while. But you didn’t see the effects until you followed people 12 years. So we’re now going to be a little more worried about ovarian cancer in this setting than we used to be. And that’s going to be something we’re all going to keep an eye on and think twice about in terms of talking to patients.”

These results help demonstrate what happens when a society invests in science on a national scale, Dr. Kurian said. “Here we have a really long-term, incredibly informative study that keeps generating knowledge to help women.”

When the WHI began, it “really was the first time that people decided it was important to systematically study women at midlife. It was a remarkable thing then that society got mobilized to do this, and we’re still seeing the benefits.”

Dr. Chlebowski disclosed receiving consulting or advisory fees from Pfizer. Dr. Teplinsky and Dr. Kurian disclosed no financial conflicts of interest.

Study Highlights Melanoma Survival Disparities in Rural vs Urban Settings

Among people diagnosed with cutaneous melanoma in the United States, those who live in rural areas have significantly lower rates of survival than those who live in urban areas, results from an analysis of data from the National Cancer Institute showed.

“Melanoma is currently the fifth most common malignancy in the United States, with approximately 106,000 new cases and 7180 reported deaths occurring in 2021,” the study’s first author, Mitchell Taylor, MD, a dermatology research fellow at the University of Nebraska, Omaha, and colleagues wrote in the abstract, which was presented during a poster session at the annual meeting of the Society for Investigative Dermatology. “Rural areas have been shown to bear a higher melanoma disease burden, yet there is a paucity of national-level studies examining these disparities.”

To characterize the rural population diagnosed with cutaneous melanoma and assess associated disparities in the United States, the researchers queried the NCI’s Surveillance, Epidemiology, and End Results database to identify individuals diagnosed with cutaneous melanoma from 2000 to 2020 (International Classification of Diseases, 3rd Edition, 8720/3 — 8780/3; Primary Site codes C44.0-C44.9). They drew from US Office of Management and Budget terminology to define and categorize rural and urban communities.

Among 391,047 patients included during the study period, binary logistic regression analysis revealed that patients in rural areas had a greater odds of being older, from ages 50 to 75 years (odds ratio [OR], 1.10; P < .001); had annual incomes < $70,000 (OR, 16.80; P < .001); had tumors located on the head and neck (OR, 1.24; P < .001); and presented with regional/distant disease (OR, 1.13; P < .001).



As for disease-specific survival, patients living in rural areas had significantly reduced survival compared with those living in urban areas (a mean of 207.3 vs 216.3 months, respectively; P < .001). Multivariate Cox regression revealed that living in a rural setting was significantly associated with reduced disease-specific survival (hazard ratio [HR], 1.10; P < .001), as was having head and neck tumors (HR, 1.41; P < .001).“Overall, this study underscores a significant decrease in disease-specific survival among rural patients diagnosed with cutaneous melanoma and establishes a significant association between rural living and high-risk primary tumor locations, particularly the head and neck,” the authors concluded.

Lucinda Kohn, MD, assistant professor of dermatology in the Centers for American Indian and Alaska Native Health at the University of Colorado at Denver, Aurora, Colorado, who was asked to comment on the results, said the findings echo the results of a recent study which characterized melanoma rates among non-Hispanic American Indian/Alaska Native individuals from 1999 to 2019.

“I suspect this decreased disease-specific survival highlights the issues our rural-residing patients face with access to dermatology care,” Dr. Kohn told this news organization. “Dermatologists are able to detect thinner melanomas than patients [and] are preferentially concentrated in metropolitan areas. Dermatologists are also the most skilled and knowledgeable to screen, diagnose, and manage melanomas. Having fewer dermatologists in rural areas impedes melanoma care for our rural-residing patients.”

Neither the researchers nor Dr. Kohn reported any relevant disclosures.

As for disease-specific survival, patients living in rural areas had significantly reduced survival compared with those living in urban areas (a mean of 207.3 vs 216.3 months, respectively; P < .001). Multivariate Cox regression revealed that living in a rural setting was significantly associated with reduced disease-specific survival (hazard ratio [HR], 1.10; P < .001), as was having head and neck tumors (HR, 1.41; P < .001).“Overall, this study underscores a significant decrease in disease-specific survival among rural patients diagnosed with cutaneous melanoma and establishes a significant association between rural living and high-risk primary tumor locations, particularly the head and neck,” the authors concluded.

Lucinda Kohn, MD, assistant professor of dermatology in the Centers for American Indian and Alaska Native Health at the University of Colorado at Denver, Aurora, Colorado, who was asked to comment on the results, said the findings echo the results of a recent study which characterized melanoma rates among non-Hispanic American Indian/Alaska Native individuals from 1999 to 2019.

“I suspect this decreased disease-specific survival highlights the issues our rural-residing patients face with access to dermatology care,” Dr. Kohn told this news organization. “Dermatologists are able to detect thinner melanomas than patients [and] are preferentially concentrated in metropolitan areas. Dermatologists are also the most skilled and knowledgeable to screen, diagnose, and manage melanomas. Having fewer dermatologists in rural areas impedes melanoma care for our rural-residing patients.”

Neither the researchers nor Dr. Kohn reported any relevant disclosures.

Features of Merkel Cell in Hispanic Patients Explored

Article Type

Wed, 06/12/2024 - 11:05

Compared with White patients with Merkel cell carcinoma (MCC), non-White Hispanic patients more commonly presented younger than 70 years of age and were more often female. In addition, the most affected site was the upper limb/shoulder, which differs from what has been reported in previous studies.

Those are key findings from a retrospective study of national cancer data that was presented during a poster session at the annual meeting of the Society for Investigative Dermatology.

“Merkel cell carcinoma is an infrequent and aggressive form of neuroendocrine skin cancer that mainly impacts individuals of White ethnicity, with a general occurrence rate of 0.7 instances per 100,000 person-years,” one of the study authors, Luis J. Borda, MD, chief dermatology resident at Eastern Virginia Medical School, Norfolk, Virginia, told this news organization. The incidence of MCC is increasing among all racial groups, especially in the Hispanic population, he added.

To determine how age, sex, and primary site of MCC differ in White vs non-White Hispanic patients, the researchers evaluated the 22 population-based cancer registries of the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program from 2000 through 2020. They reported categorical variables as counts and percentages and used chi-square test with Yates’s correction to assess the association between categorical variables.

Of the 17,920 MCCs identified by the researchers, 40 (0.22%) were in non-White Hispanic patients. Compared with the White patients with MCC, significantly fewer non-White Hispanic patients were age 70 years or older (50% vs 72.1%, respectively; P < .001), and MCC was more common in female non-White Hispanic patients (23, or 57.5%), while White patients with MCC were predominantly male (11,309, or 63.2%; P < .05). “This suggests that MCC in non-White Hispanic patients may involve different risk factors related to age beyond just cumulative UV exposure and aging-related immunosenescence, which may additionally account for the higher prevalence of females in this cohort, as historically male outdoor occupation has resulted in increased lifetime cumulative UV exposure,” Dr. Borda said.



The head and neck were the most common sites of disease involvement in White patients (41.9% vs 27.5% in non-White Hispanic patients; P = .09), while the upper limb and shoulder were the most common sites of disease involvement in non-White Hispanic patients (37.5% vs 23.8% in White patients; P = .06). This finding “differs from previous studies showing head/neck being the most common site in Hispanics,” Dr. Borda said, adding that this could be a result of White patients not being included in the Hispanic cohort in this study. “Because non-White Hispanic patients have darker skin, they may have proportionally more cases on sun-protected skin, as is described by the present data, suggesting that they are less likely to have UV-driven MCC.”

The study “highlights distinct demographic and clinical characteristics of MCC among non-White Hispanic patients compared to their White counterparts, emphasizing the importance of considering race/ethnicity in understanding the epidemiology of this rare but increasingly prevalent cancer,” Dr. Borda said. He and his co-authors are planning to do further research on the increasing incidence of MCC in non-White Hispanic patients and on staging at diagnosis compared to White patients.

Dr. Borda acknowledged certain limitations of the analysis, including the small sample size in the non-White Hispanic group, the retrospective nature of SEER data, selection bias, and the potential for underreporting. He and his co-authors reported having no financial disclosures.

FMT Could Prevent Recurrence of Hepatic Encephalopathy in Patients With Cirrhosis

Article Type
Changed
Wed, 06/12/2024 - 09:52

Fecal microbiota transplantation (FMT), also known as intestinal microbiota transplantation, significantly reduced recurrence of hepatic encephalopathy, compared with placebo, in patients with cirrhosis on standard-of-care treatment, results of a phase 2 randomized controlled trial show. 

“Not only was FMT more beneficial, but also it didn’t matter which route of administration was used — oral or enema — which is good because people don’t really like enemas,” said Jasmohan S. Bajaj, MD, AGAF, professor, School of Medicine, Virginia Commonwealth University, Richmond, and hepatologist at Richmond VA Medical Center.

Dr. Jasmohan S. Bajaj


Donor background (including vegan or omnivore) and dose range also did not affect the efficacy of FMT, Dr. Bajaj said. 

Dr. Bajaj presented the findings (Abstract GS-001) at the opening session of the annual European Association for the Study of the Liver (EASL) Congress 2024. 

Hepatic encephalopathy is a complication of advanced liver disease that causes a dementia-like state. Standard treatment with lactulose and rifaximin often results in a lack of patient response, meaning the patient is constantly being readmitted to the hospital, Dr. Bajaj said.

“This is a burden for the family as well as the patients,” and is very difficult to manage from a clinical and psychosocial perspective, he said in an interview.

With FMT, “we are transferring an ecosystem of good microbes,” which modifies the gut microbiome in patients with advanced liver disease and reduces associated brain toxicity, Dr. Bajaj explained.
 

Resetting the Gut

The double-blind, randomized, placebo-controlled trial enrolled a total of 60 patients with cirrhosis who had experienced hepatic encephalopathy. Aged 61-65 years, participants had Model for End-Stage Liver Disease (MELD) scores of 12-13, all were taking lactulose and rifaximin, and all had experienced their last hepatic encephalopathy episode 8-13 months prior. 

Participants had similar baseline cognition, Sickness Impact Profile (SIP), and cirrhosis severity. Those with recent infections, taking other antibiotics, with a MELD score > 22, had received a transplant, or were immunosuppressed were excluded. 

Study participants were divided into four dose administration groups (n = 15 each): oral and enema active FMT therapy (group 1), oral active FMT and enema placebo (group 2), oral placebo and enema active FMT (group 3), and oral and enema placebo (group 4). 

The range of FMT dose frequency was zero (all placebo), or one, two, or three FMT administrations, each given 1 month apart. 

Two thirds of those receiving active FMT were given omnivore-donor FMT, and one third were given vegan-donor FMT, in addition to receiving standard of care. 

“Colony-forming units were standard and the same whether given via oral capsule or enema,” Dr. Bajaj said. This is “similar to what we used in our phase 1 study.”

Intent-to-treat (ITT) analysis was performed with 6-month data. The primary outcomes were safety and hepatic encephalopathy recurrence defined as ≥ grade 2 on West-Haven criteria. Secondary outcomes included other adverse events, changes in infections, severity of cirrhosis and cognition, and patient-reported outcomes. A statistical regression for hepatic encephalopathy recurrence was also performed. Patients were followed for 6 months or until death.
 

One Dose of FMT Better Than None

Hepatic encephalopathy recurrence was highest (40%) in group 4 patients, compared with those in group 1 (13%), group 2 (13%), and group 3 (0%), as were liver-related hospitalizations (47% vs 7%-20%). 

SIP total/physical and psych scores improved with FMT (P = .003).

When all patients were included in the analysis, the hepatic encephalopathy recurrence was related to dose number (odds radio [OR], 0.27; 95% CI, 0.10-0.79; P = .02), male sex (OR, 0.16; 95% CI, 0.03-0.89; P = .04), and physical SIP (OR, 1.05; 95% CI, 1.01-1.10, P = .05). However, when analyzing results from FMT recipients only, FMT dose, route of administration, and donor source were not found to affect recurrence. 

Of those on placebo alone, six patients (40%) had a recurrence, compared with four on FMT (8.8%) in the combined FMT groups. 

“As long as a patient received at least one FMT dose, they had a better response than a patient who had none,” Dr. Bajaj said.

Six patients dropped out; two in group 1 died after hepatic encephalopathy and falls, and one in group 2 died after a seizure. Three others did not return for follow-up visits. Four patients developed infections, including spontaneous bacterial peritonitis, cholecystitis, and cellulitis, all unrelated to FMT. 

“I think many patients in Western countries are underserved because apart from lactulose and rifaximin, there is little else to give them,” Dr. Bajaj said. “The assumption is because rifaximin kills everything, we shouldn’t give FMT. But here, we administered it to a harsh and hostile wasteland of microbiota, and it still got a toehold and generated a reduction in hepatic encephalopathy.”

He pointed out that in smaller prior studies, the effects lasted up to 1 year. 
 

Setting the Stage for Phase 3 Trials

Dr. Bajaj noted that this phase 2 study sets the stage for larger phase 3 trials in patients not responding to first-line therapy. 

“Given how well-tolerated and effective FMT appears to be in these patients, if the larger phase 3 trial shows similar results, I can imagine FMT becoming a standard therapy,” said Colleen R. Kelly, MD, AGAF, gastroenterologist at Brigham and Women’s Hospital and Harvard Medical School, Boston, who was not involved in the study.

This study was built on Dr. Bajaj’s prior work that established the safety of FMT by enema, she added, stressing that this new research was incredibly important in these immunocompromised patients who are at higher risk for infection transmission. 

That the administration route doesn’t matter is also an important finding as oral administration is much more feasible than enema, said Dr. Kelly, who went on to point out the importance of finding an alternative to rifaximin and lactulose, which are often poorly tolerated. 

The study highlights the central role played by the gut microbiota in dysbiosis in the pathophysiology of hepatic encephalopathy, Dr. Kelly said. “It is another exciting example of how gut microbiota can be manipulated to treat disease.”

Dr. Bajaj and Dr. Kelly report no relevant financial relationships to this study.

This study was built on Dr. Bajaj’s prior work that established the safety of FMT by enema, she added, stressing that this new research was incredibly important in these immunocompromised patients who are at higher risk for infection transmission. 

That the administration route doesn’t matter is also an important finding as oral administration is much more feasible than enema, said Dr. Kelly, who went on to point out the importance of finding an alternative to rifaximin and lactulose, which are often poorly tolerated. 

The study highlights the central role played by the gut microbiota in dysbiosis in the pathophysiology of hepatic encephalopathy, Dr. Kelly said. “It is another exciting example of how gut microbiota can be manipulated to treat disease.”

Dr. Bajaj and Dr. Kelly report no relevant financial relationships to this study.

The Positive Effects of Exercise in MS

Article Type

Wed, 06/12/2024 - 09:41

Exercise has a long history in multiple sclerosis (MS). In 1838, the Scottish physician John Abercrombie reported that a patient with “a diminution of muscular power,” who could walk but only unsteadily, decided after various failed treatments like “evacuations and spare diet” to try “violent exercise.” He walked 5-6 miles on a warm evening, as quickly as he was able, and returned home “much fatigued, and considerably heated. Next morning he had severe pains in the calves of his legs, but his other complaints were much diminished, and in a few days disappeared. He has ever since enjoyed good health,” Dr. Abercrombie was quoted in Multiple Sclerosis: The History of a Disease by T. Jock Murray.

The first randomized, controlled trial of an exercise intervention for MS didn’t appear in the literature until 1988, but more than 200 have been published in the years since, according to Robert Motl, PhD, who spoke about exercise interventions for MS at the annual meeting of the Consortium of Multiple Sclerosis Centers.

In fact, the evidence shows that exercise can improve walking performance and quality of life. “When we look at what we might call the unseen symptoms, we can see the exercise training is very effective at reducing fatigue in people with MS. It’s very effective at reducing depressive mood in individuals living with MS. There is moderate evidence that it can improve mobility, particularly lower extremity mobility and walking performance in individuals living with multiple sclerosis, as well as balance. And lastly, we see consistent evidence that exercise training can improve quality of life,” said Dr. Motl, who is a professor of kinesiology and nutrition at University of Illinois, Chicago.

There is less evidence that exercise training helps mobility, anxiety, pain, and participation, he said.

Dr. Motl showed the results of various meta-analyses that he co-authored of randomized, controlled trials (RCTs) of exercise training. One meta-analysis of 20 trials that examined the effect on fitness found an effect size of 0.47, which was about one-half of a standard deviation, and is considered to be a clinically meaningful effect. There was also about a 20% improvement in aerobic capacity, and this improves the capacity for maintaining independence, according to Dr. Motl. “That’s huge as individuals who are living with MS over a long-term period of time are aging with this chronic disease and independence does become an issue later in life. We maybe can forestall some of that,” he said.

Another meta-analysis of 17 RCTs examining exercise training and fatigue found a similar effect size of 0.452. When the authors limited the analysis to studies that used the Fatigue Severity Score and its benchmark of clinically significant fatigue of 4.0, “they were able to reduce the mean fatigue severity score below 4.0, meaning you’re taking individuals who have severe fatigue and reducing their fatigue below a threshold of severity that impacts everyday life. So this is something that is clinically meaningful and relevant to the lives of individuals with MS,” he said.

With respect to depression, a meta-analysis of 14 randomized, controlled trials found an effect size of 0.55 standard deviations. The researchers found that the effect size was associated with the number of days per week: The effect was size was doubled among individuals who exercised 3 or more times per week. Another meta-analysis of walking found an average 2-second improvement in walking speed and about a 40-meter improvement in walking endurance. “I believe that’s pretty comparable to what you see with Ampyra (dalfampridine) and its effects on walking speeds, so we’re seeing something that’s as good as a pharmacological agent for managing walking in MS,” said Dr. Motl.

Another meta-analysis of health-related quality of life found that the effect on the physical domain was about twice as large as the effect on mental health–related quality of life. “I think that makes sense because when you are engaging in exercise, it’s a physically invoking stimulus. As you see adaptations, your perceptions of your physical health improve,” said Dr. Motl.

Dr. Motl also addressed safety. There have been some concerns that exercise could lead to temporary worsening of symptoms, “but it was blown up into a major, major problem when it is only 5% of individuals who have these sorts of severe problems,” said Dr. Motl. A systematic review in 2023 found an adverse event rate of 1.2% in the control groups and 2.0% in the exercise groups. This was about the same rates that are seen in the general population, according to Dr. Motl. A consistent adverse event was lower back pain, but further analysis showed it was only reported with resistance training. “The beauty of that is that we have incredible people in the field of MS, who know how to deliver resistance training more safely. And if we do that more effectively, we can avoid this very common injury with exercise training,” said Dr. Motl.

The review also found a 25% reduction in relapses. “It was very interesting. I don’t know if we want to say exercise is a disease-modifying behavior yet, but that effect at the time that these studies were done was about the same as some of the early disease-modifying therapies, showing the same degree of reduction of relapse rate,” said Dr. Motl.

Dr. Motl also discussed updated guidelines for exercise in patients with mild to moderate MS, as well as Parkinson’s disease and stroke survivors. The general advice is for 2-3 days of moderate aerobic exercise per week, beginning at 10 minutes and gradually increasing to 30 minutes per session. The newer guidelines added an option for advanced aerobic exercise, which can be up to 5 times per week and up to 40 minutes per session. Activities include ergometry, walking, aquatics, and elliptical machines for general aerobic exercise, while advanced exercise can also include running or road cycling. Resistance exercise can be done 2-3 times per week with 1-3 sets of 8-15 repetitions, with a total of 5-10 exercises. The authors recommend weight machines, free weights, or resistance bands.

Dr. Motl has received funding from the Department of Defense, National Institutes of Health, Patient-Centered Outcomes Research Institute, National Multiple Sclerosis Society, and Bristol Myers Squibb Foundation.

Chemo May Benefit Some Older Patients With Metastatic Pancreatic Cancer

Article Type
Changed
Tue, 06/11/2024 - 21:40

 

TOPLINE:

Some vulnerable older patients with untreated metastatic pancreatic cancer can benefit from chemotherapy, but only if they can tolerate enough cycles of treatment, according to results of the randomized phase 2 GIANT study.

METHODOLOGY:

Pancreatic cancer is most often diagnosed in adults aged 65 years or older. Providing cancer treatment for this older, often vulnerable, population comes with significant challenges and can lead to worse survival.

To examine real-world outcomes of older adults with untreated metastatic pancreatic cancer, researchers recruited patients aged 70 years or older and performed a geriatric assessment to identify comorbidities, cognitive issues, and other geriatric abnormalities.

Those who were deemed “fit” (ie, with no geriatric abnormalities) were assigned to receive off-study standard-of-care treatment, whereas those classified as “frail” (ie, with severe abnormalities) received off-study supportive care.

The remaining 176 “vulnerable” patients with mild to moderate geriatric abnormalities completed a geriatric and quality-of-life assessment and were then randomly assigned to receive either dose-reduced 5-fluorouracil (5-FU), leucovorin plus liposomal irinotecan (n = 88) or modified gemcitabine plus nab-paclitaxel (n = 88) every 2 weeks. Ultimately, 79 patients started the 5-FU combination and 75 received gemcitabine plus nab-paclitaxel. Patients were assessed every 8 weeks until disease progression or intolerance.

Overall, patients had a median age of 77 years; 61.9% were aged 75 years or older. About half were female, and 81.5% were White. The majority (87.5%) had a performance status of 0 or 1.

TAKEAWAY:

  • Median overall survival was 4.7 months in the gemcitabine plus nab-paclitaxel arm and 4.4 months in the 5-FU combination group, with no significant survival difference observed between the two arms (P = .72).
  • When the overall survival analysis was restricted to patients who received at least 4 weeks, or two cycles, of treatment (about 62% of patients), the median overall survival across the two treatment arms reached 8.0 months, in line with expectations for these regimens.
  • Patient stratification revealed that those with a performance status of 2 had significantly worse overall survival than those with a status of 0: 1.4 months vs 6.9 months, respectively (hazard ratio [HR], 2.77; P < .001). A similar divide was seen when patients were stratified by physical/functional status and well-being. Age, however, did not significantly influence the results.
  • Overall, more than half of patients experienced grade 3 or higher adverse events. Just over 38% of patients received only one to three cycles of therapy, whereas 26% remained on treatment for 12 or more cycles. The adverse event rates were similar between the two regimens, but the toxicity profile was slightly different — the researchers, for instance, observed more peripheral neuropathy with gemcitabine plus nab-paclitaxel and more diarrhea in the 5-FU combination arm.

IN PRACTICE:

  • Overall, the “survival outcomes among vulnerable older patients were lower than expected, with high percentage of patients not able to start treatment, or complete one month of therapy due to clinical deterioration,” said study presenter Efrat Dotan, MD, chief, Division of Gastrointestinal Medical Oncology, Fox Chase Cancer Center, Philadelphia. 
  • “For vulnerable older adults who can tolerate treatment, these two regimens provide clinicians with options for tailoring therapy based on toxicity profile,” Dr. Dotan added. But “tools are needed to better identify patients who can benefit from treatment.”
  • The results underline the need to perform geriatric assessments, as opposed to merely looking at performance status, commented David F. Chang, PhD, MS, MBBS, professor of Surgical Oncology, University of Glasgow, Scotland, who was not involved in the study. 
 

 

SOURCE:

The research, presented at the 2024 annual meeting of the American Society of Clinical Oncology, was funded by the National Cancer Institute and the Eastern Cooperative Oncology Group.

LIMITATIONS:

Dr. Chang noted that the study did not reveal which treatment regimen was more effective.

DISCLOSURES:

Dr. Dotan declared relationships with Agenus, Amgen, G1 Therapeutics, Incyte, Olympus, and Taiho Pharmaceutical and institutional relationships with Dragonfly Therapeutics, Gilead Sciences, Ipsen, Kinnate Biopharma, Leap Therapeutics, Lilly, Lutris, NGM Biopharmaceuticals, Relay Therapeutics, and Zymeworks.
