For frontal fibrosing alopecia (FFA), a disease with no approved therapies, topical delgocitinib attenuated inflammation and generated hair regrowth in women in a controlled phase 2a trial.

“This is an exciting avenue for FFA if the data are recapitulated in a larger population. It could be an important new treatment option,” said Maryanne Senna, MD, director at Lahey Hospital & Medical Center’s Hair Loss Center of Excellence, Burlington, Massachusetts, and assistant dermatology professor at Harvard Medical School, Boston, Massachusetts.

In a design characterized as “exploratory,” the trial had two parts: a randomized, double-blind, vehicle-controlled intervention for 12 weeks, followed by an open-label extension of topical delgocitinib for all participants for another 12 weeks. 

The primary efficacy endpoint was change in the molecular signature of FFA inflammation at 12 weeks. Clinical improvement was monitored with both trichoscopic images capturing the numbers of hairs and follicular units at 12 weeks and clinical severity scores through week 24. In a topical cream formulation, the Janus kinase inhibitor (JAKi) delgocitinib was associated with favorable activity for both. 
 

Some Hair Regrowth for All

“At 24 weeks, all patients achieved some degree of hair regrowth and a stabilization of disease based on hairline measurements,” Senna reported in a late-breaking news session at the 2024 European Academy of Dermatology and Venereology (EADV) Congress

On the clinical endpoints, Senna noted an upward trajectory in clinical improvement at the completion of the study.

The 30 participants were randomly assigned in a 1:1 ratio to receive delgocitinib cream in a concentration of 20 mg/g or vehicle cream applied twice daily for 12 weeks. At the end of this double-blind period, patients on vehicle were crossed over to the active therapy, and all patients were monitored for another 12 weeks in an open-label extension. 

The change from baseline in FFA biomarkers was selected as the primary endpoint based on previous work showing up-regulation in the expression of the Th1 biomarkers CXCL9, CXCL10, and interferon gamma in lesional vs nonlesional scalp in patients with FFA. 

When biopsies at the end of 12 weeks in the double-blind phase of the study were compared with the baseline biopsies, researchers found a decrease in expression of the three local inflammation markers in all patients receiving the JAKi, but not in those receiving the vehicle cream. In this small patient sample, only the reduction in expression of CXCL9, a cytokine known for differentiation and promotion of leukocytes, reached statistical significance (P < .05).

But in an analysis involving the expression of multiple genes, “lesions treated with delgocitinib had a 4% improvement in normalization toward a nonlesional transcriptomic profile, while patients treated with vehicle had a 33% worsening,” Senna reported. The difference was highly significant (P < .001).

Furthermore, the decrease in total Lichen Planopilaris Activity Index and FFA severity scores were numerically and statistically greater (P = .023) in the active-treatment arm than in the vehicle arm by the end of the double-blind part of the trial, she said.

On trichoscopy, there was an increased number of hairs and follicular units at 12 weeks relative to baseline among those treated with topical delgocitinib but a reduction in those treated with vehicle.
 

JAKi Patients Gained Hair, Vehicle Patients Lost Hair

On the basis of hair count per square centimeter from baseline, delgocitinib-treated patients gained on average of seven hairs whereas vehicle recipients lost an average of 11 hairs at 24 weeks, Senna reported.

Patients originally treated with vehicle did improve in most outcome measures in the open-label extension of the experimental treatment after crossover, but they did not catch up to those initially randomized to delgocitinib because of further accrual of favorable changes in the active-treatment group over time.

“There were no adverse events associated with active therapy or vehicle, including application-site reactions,” Senna said. The one between-group difference was a higher rate of COVID-19, but this was greater in the control arm.

All 30 of the participants in this study were women, and all had moderate to severe disease at enrollment. The median age was 64 years. Because of the predominant population at the hair loss center, all but one of the participants were White, and one participant was Asian. 

Characterizing FFA as “devastating and disfiguring,” Senna, who specializes in the care of alopecia, noted that this a difficult disease to control with the off-label strategies that are now used. The slow progress to identify treatments for FFA is illustrated by the fact that only one other double-blind and randomized trial has ever been conducted in FFA, she said.
 

Exploratory Study Supports Anecdotal Experience

On the basis of prior anecdotal experience with JAKi treatment for FFA, Senna said, “I do think that it is possible to get largely clear skin with this therapy.” However, she is now hoping for definitive trials to better characterize the efficacy and safety of oral and topical therapies, perhaps used sequentially to maintain clinical improvement.

In light of the limited current options, Menno de Rie, MD, PhD, professor of dermatology at the University of Amsterdam in the Netherlands, called these data “very inspiring and hopeful.” He suggested the promise of this therapy was reinforced by the upward trajectory of the biomarkers and clinical improvement over the study period. 

“Any improvement in treatment options would be welcome, because we do not [have] any reliable therapies for this condition,” de Rie, who was not an investigator, said in an interview after the presentation. 

Ultimately, Senna said, once effective therapy is established, the goal will be to start as early as possible in the disease process. She noted that there is evidence that prompt therapy can reverse the disorder, not just prevent progression.

“If you can get to the hair follicles before the point of no return, there is [a] chance [of] follicular rescue,” she said.

Delgocitinib cream (Anzupgo) was approved in Europe for treating chronic hand eczema in late September and is under review for the same indication in the United States. 

Senna has financial relationships with Arena, Concert, Eli Lilly, Pfizer, and Leo Pharma, which provided funding for this study. de Rie reported no potential conflicts of interest.

MDMA Is Off the Table, So What’s Next for PTSD?

Article Type

It has been 24 years since a pharmaceutical was last approved for posttraumatic stress disorder (PTSD). The condition is notoriously difficult to treat, with up to 40% patients finding no relief from symptoms through psychotherapy or current medications.

Many clinicians, advocates, and patients had pinned their hopes on the psychedelic drug midomafetamine with assisted therapy (MDMA-AT). However, in August, the US Food and Drug Administration (FDA) rejected it. At this point, it’s unclear when the therapy will be available, if ever.

“Not getting the FDA approval of any drug at this point is a setback for the field,” Lori Davis, MD, a senior research psychiatrist at the Birmingham Veterans Affairs (VA) Health Care System in Birmingham, Alabama, told Medscape Medical News.

Having an FDA-approved product would have helped increase public awareness of PTSD and driven interest in developing new therapies, said Davis, who is also adjunct professor of psychiatry at the Heersink School of Medicine, University of Alabama at Birmingham.
 

A Treatable Condition

So with MDMA-AT off the table, where does the field go next? 

public meeting in September hosted by the Reagan-Udall Foundation for the FDA in sought to answer that question. Agency officials joined representatives from the Department of Defense (DoD) and VA, patients, advocates, and industry representatives to discuss the current treatment landscape and what can be done to accelerate development of PTSD treatment.

Despite the common belief that PTSD is intractable, it “is a treatable condition,” Paula P. Schnurr, PhD, executive director of the VA National Center for PTSD, said at the meeting.

“There are effective treatments that work well for a lot of people, although not everyone has a satisfactory response,” she added.

The most effective psychotherapies are “trauma-focused,” and include cognitive processing therapy, eye movement desensitization and reprocessing, and prolonged exposure, according to the VA National Center for PTSD.

Three drugs have been approved by the FDA for PTSD: Venlafaxine (Effexor) in 1993, sertraline (Zoloft) in 1999, and paroxetine (Paxil) in 2000.

However, as the September meeting demonstrated, more therapies are needed.

“It’s clear to FDA and the federal government at large that there is an unmet need for safe and effective therapies to treat PTSD,” Bernard Fischer, MD, deputy director of the Division of Psychiatry in the Office of New Drugs at FDA’s Center for Drug Evaluation and Research, said at the meeting.

There is no shortage of research, Fischer added. Nearly 500 trials focused on PTSD are listed on clinicaltrials.gov are recruiting participants now or plan to soon.

Unsurprisingly, one of the primary drivers of PTSD therapeutics research is the VA. About 14% of the 5.7 million veterans who received care through the VA in 2023 had a diagnosis of PTSD.

“The US military is currently losing thousands of service members each year to PTSD- related disability discharges,” US Army Maj. Aaron Wolfgang, MD, a psychiatrist at the Walter Reed National Military Medical Center, said at the meeting. Only about 12%-20% of patients achieve remission with conventional therapies, added Wolfgang, who also is an assistant professor at the Uniformed Services University.

“For these reasons, establishing better treatments for PTSD is not only a matter of humanitarianism but also a pressing matter of national security,” he said.

The VA has committed at least $230 million to more than 140 active research projects in PTSD, Miriam J. Smyth, PhD, acting director of the clinical science, research and development service at the VA, said at the Reagan-Udall meeting.

One of the VA projects is the PTSD psychopharmacology initiative, which began in 2017 and now has 14 active clinical trials, said Smyth, who is also acting director for brain behavior and mental health at the VA. The first study should be finished by 2025.

The Million Veteran Program, with more than 1 million enrollees, has led to the discovery of genes related to re-experiencing traumatic memories and has confirmed that both PTSD and traumatic brain injury are risk factors for dementia, Smyth said.

The DoD has created a novel platform that establishes a common infrastructure for testing multiple drugs, called M-PACT. The platform allows sharing of placebo data across treatment arms. Drugs cycle off the platform if evidence indicates probability of success or failure.

Four trials are actively recruiting veterans and current service members. One is looking at vilazodone, approved in 2011 for major depressive disorder. It is being compared with placebo and fluoxetine in a trial that is currently recruiting.

Another trial will study daridorexant (sold as Quviviq), an orexin receptor antagonist, against placebo. The FDA approved daridorexant in 2022 as an insomnia treatment. A core issue in PTSD is sleep disruption, noted Davis.
 

 

 

New Therapies on the Way

Separately, Davis and colleagues are also studying methylphenidate, the stimulant used for attention-deficit/hyperactivity disorder. It may help with neurocognitive complaints and reduce PTSD symptoms, said Davis.

Because it is generic, few pharmaceutical manufacturers are likely to test it for PTSD, she said. But eventually, their work may lead a company to test newer stimulants for PTSD, she said.

Another potential therapeutic, BNC210, received Fast Track designation for PTSD from the FDA in 2019. Bionomics Limited in Australia will soon launch phase 3 trials of the investigational oral drug, which is a negative allosteric modulator of the alpha-7 nicotinic acetylcholine receptor. In late July, the company announced “ favorable feedback” from the agency on its phase 2 study, which led to the decision to move forward with larger trials.

Researchers at Brigham and Women’s Hospital have just reported that they may have found a target within the brain that will allow for transcranial magnetic stimulation (TMS) to ameliorate PTSD symptoms. They published results of a mapping effort in Nature Neuroscience and reported on one patient who had improved symptoms after receiving TMS for severe PTSD.

But perhaps one of the most promising treatments is a combination of sertraline and the new psychiatric medication brexpiprazole.

Brexpiprazole was developed by Otsuka Pharmaceutical and approved in the United States in 2015 as an adjunctive therapy to antidepressants for major depressive disorder and as a treatment for schizophrenia. In 2023, the FDA approved it for Alzheimer’s-related agitation. However, according to Otsuka, its mechanism of action is unknown.

Its efficacy may be mediated through a combination of partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors, antagonist activity at serotonin 5-HT2A receptors, as well as antagonism of alpha-1B/2C receptors, said the company.

“It is the combination, rather than either alone, that’s going to have that broad synergistic pharmacology that is obviously potent for ameliorating the symptoms of PTSD,” said Davis, who has received consulting fees from Otsuka. “That’s an exciting development.”

Otsuka and partner Lundbeck Pharmaceuticals reported results in May from the companies’ phase 2 and 3 randomized clinical trials. The therapy achieved a statistically significant reduction (P <.05) in PTSD symptoms compared with sertraline plus placebo. This was without any supplemental psychotherapy.

The FDA accepted the companies’ new drug application in June and is expected to make a decision on approval in February 2025.
 

The Potential of Psychedelics

Though Lykos Therapeutics may have to go back to the drawing board on its MDMA-AT, psychedelics still have potential as PTSD therapies, Smyth said, who added that the VA is continuing to encourage study of MDMA and other psychedelic agents.

The VA issued a call for proposals for research on psychedelics in January, focused on MDMA or psilocybin in combination with psychotherapy. The administration received the first wave of applications early in the summer.

Scientific peer review panels made up of research experts from within and outside the VA have reviewed the applications and funding announcements are expected this fall, Smyth said.

Wolfgang, the Army psychiatrist, said, “Under the psychedelic treatment research clinical trial award, we welcome investigators to apply to what we anticipate will usher in a new era of innovation and hope for service members and their families who need it the most.”

Psychedelic studies are also proceeding without VA funding, as they have for years, when most of the trials were backed by universities or foundations or other private money. Johns Hopkins University is recruiting for a study in which patients would receive psilocybin along with trauma-focused psychotherapy, as is Ohio State University.

London-based Compass Pathways said in May that it successfully completed a phase 2 trial of Comp360, its synthetic psilocybin, in PTSD. The company has started a phase 3 study in treatment-resistant depression but has not given any further updates on PTSD.

Davis said that she believes that the FDA’s rejection of Lykos won’t lead to a shutdown of exploration of psychedelics.

“I think it informs these designs going forward, but it doesn’t eliminate that whole field of research,” she said.

Davis reported receiving consulting fees from Boehringer Ingelheim and Otsuka and research funding from Alkermes, the Patient-Centered Outcomes Research Institute, and the VA. Schnurr, Fischer, Smyth, and Wolfgang reported no relevant disclosures.

Its efficacy may be mediated through a combination of partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors, antagonist activity at serotonin 5-HT2A receptors, as well as antagonism of alpha-1B/2C receptors, said the company.

“It is the combination, rather than either alone, that’s going to have that broad synergistic pharmacology that is obviously potent for ameliorating the symptoms of PTSD,” said Davis, who has received consulting fees from Otsuka. “That’s an exciting development.”

Otsuka and partner Lundbeck Pharmaceuticals reported results in May from the companies’ phase 2 and 3 randomized clinical trials. The therapy achieved a statistically significant reduction (P <.05) in PTSD symptoms compared with sertraline plus placebo. This was without any supplemental psychotherapy.

The FDA accepted the companies’ new drug application in June and is expected to make a decision on approval in February 2025.
 

The Potential of Psychedelics

Though Lykos Therapeutics may have to go back to the drawing board on its MDMA-AT, psychedelics still have potential as PTSD therapies, Smyth said, who added that the VA is continuing to encourage study of MDMA and other psychedelic agents.

The VA issued a call for proposals for research on psychedelics in January, focused on MDMA or psilocybin in combination with psychotherapy. The administration received the first wave of applications early in the summer.

Scientific peer review panels made up of research experts from within and outside the VA have reviewed the applications and funding announcements are expected this fall, Smyth said.

Wolfgang, the Army psychiatrist, said, “Under the psychedelic treatment research clinical trial award, we welcome investigators to apply to what we anticipate will usher in a new era of innovation and hope for service members and their families who need it the most.”

Psychedelic studies are also proceeding without VA funding, as they have for years, when most of the trials were backed by universities or foundations or other private money. Johns Hopkins University is recruiting for a study in which patients would receive psilocybin along with trauma-focused psychotherapy, as is Ohio State University.

London-based Compass Pathways said in May that it successfully completed a phase 2 trial of Comp360, its synthetic psilocybin, in PTSD. The company has started a phase 3 study in treatment-resistant depression but has not given any further updates on PTSD.

Davis said that she believes that the FDA’s rejection of Lykos won’t lead to a shutdown of exploration of psychedelics.

“I think it informs these designs going forward, but it doesn’t eliminate that whole field of research,” she said.

Davis reported receiving consulting fees from Boehringer Ingelheim and Otsuka and research funding from Alkermes, the Patient-Centered Outcomes Research Institute, and the VA. Schnurr, Fischer, Smyth, and Wolfgang reported no relevant disclosures.

It has been 24 years since a pharmaceutical was last approved for posttraumatic stress disorder (PTSD). The condition is notoriously difficult to treat, with up to 40% patients finding no relief from symptoms through psychotherapy or current medications.

Many clinicians, advocates, and patients had pinned their hopes on the psychedelic drug midomafetamine with assisted therapy (MDMA-AT). However, in August, the US Food and Drug Administration (FDA) rejected it. At this point, it’s unclear when the therapy will be available, if ever.

“Not getting the FDA approval of any drug at this point is a setback for the field,” Lori Davis, MD, a senior research psychiatrist at the Birmingham Veterans Affairs (VA) Health Care System in Birmingham, Alabama, told Medscape Medical News.

Having an FDA-approved product would have helped increase public awareness of PTSD and driven interest in developing new therapies, said Davis, who is also adjunct professor of psychiatry at the Heersink School of Medicine, University of Alabama at Birmingham.
 

A Treatable Condition

So with MDMA-AT off the table, where does the field go next? 

public meeting in September hosted by the Reagan-Udall Foundation for the FDA in sought to answer that question. Agency officials joined representatives from the Department of Defense (DoD) and VA, patients, advocates, and industry representatives to discuss the current treatment landscape and what can be done to accelerate development of PTSD treatment.

Despite the common belief that PTSD is intractable, it “is a treatable condition,” Paula P. Schnurr, PhD, executive director of the VA National Center for PTSD, said at the meeting.

“There are effective treatments that work well for a lot of people, although not everyone has a satisfactory response,” she added.

The most effective psychotherapies are “trauma-focused,” and include cognitive processing therapy, eye movement desensitization and reprocessing, and prolonged exposure, according to the VA National Center for PTSD.

Three drugs have been approved by the FDA for PTSD: Venlafaxine (Effexor) in 1993, sertraline (Zoloft) in 1999, and paroxetine (Paxil) in 2000.

However, as the September meeting demonstrated, more therapies are needed.

“It’s clear to FDA and the federal government at large that there is an unmet need for safe and effective therapies to treat PTSD,” Bernard Fischer, MD, deputy director of the Division of Psychiatry in the Office of New Drugs at FDA’s Center for Drug Evaluation and Research, said at the meeting.

There is no shortage of research, Fischer added. Nearly 500 trials focused on PTSD are listed on clinicaltrials.gov are recruiting participants now or plan to soon.

Unsurprisingly, one of the primary drivers of PTSD therapeutics research is the VA. About 14% of the 5.7 million veterans who received care through the VA in 2023 had a diagnosis of PTSD.

“The US military is currently losing thousands of service members each year to PTSD- related disability discharges,” US Army Maj. Aaron Wolfgang, MD, a psychiatrist at the Walter Reed National Military Medical Center, said at the meeting. Only about 12%-20% of patients achieve remission with conventional therapies, added Wolfgang, who also is an assistant professor at the Uniformed Services University.

“For these reasons, establishing better treatments for PTSD is not only a matter of humanitarianism but also a pressing matter of national security,” he said.

The VA has committed at least $230 million to more than 140 active research projects in PTSD, Miriam J. Smyth, PhD, acting director of the clinical science, research and development service at the VA, said at the Reagan-Udall meeting.

One of the VA projects is the PTSD psychopharmacology initiative, which began in 2017 and now has 14 active clinical trials, said Smyth, who is also acting director for brain behavior and mental health at the VA. The first study should be finished by 2025.

The Million Veteran Program, with more than 1 million enrollees, has led to the discovery of genes related to re-experiencing traumatic memories and has confirmed that both PTSD and traumatic brain injury are risk factors for dementia, Smyth said.

The DoD has created a novel platform that establishes a common infrastructure for testing multiple drugs, called M-PACT. The platform allows sharing of placebo data across treatment arms. Drugs cycle off the platform if evidence indicates probability of success or failure.

Four trials are actively recruiting veterans and current service members. One is looking at vilazodone, approved in 2011 for major depressive disorder. It is being compared with placebo and fluoxetine in a trial that is currently recruiting.

Another trial will study daridorexant (sold as Quviviq), an orexin receptor antagonist, against placebo. The FDA approved daridorexant in 2022 as an insomnia treatment. A core issue in PTSD is sleep disruption, noted Davis.
 

 

 

New Therapies on the Way

Separately, Davis and colleagues are also studying methylphenidate, the stimulant used for attention-deficit/hyperactivity disorder. It may help with neurocognitive complaints and reduce PTSD symptoms, said Davis.

Because it is generic, few pharmaceutical manufacturers are likely to test it for PTSD, she said. But eventually, their work may lead a company to test newer stimulants for PTSD, she said.

Another potential therapeutic, BNC210, received Fast Track designation for PTSD from the FDA in 2019. Bionomics Limited in Australia will soon launch phase 3 trials of the investigational oral drug, which is a negative allosteric modulator of the alpha-7 nicotinic acetylcholine receptor. In late July, the company announced “ favorable feedback” from the agency on its phase 2 study, which led to the decision to move forward with larger trials.

Researchers at Brigham and Women’s Hospital have just reported that they may have found a target within the brain that will allow for transcranial magnetic stimulation (TMS) to ameliorate PTSD symptoms. They published results of a mapping effort in Nature Neuroscience and reported on one patient who had improved symptoms after receiving TMS for severe PTSD.

But perhaps one of the most promising treatments is a combination of sertraline and the new psychiatric medication brexpiprazole.

Brexpiprazole was developed by Otsuka Pharmaceutical and approved in the United States in 2015 as an adjunctive therapy to antidepressants for major depressive disorder and as a treatment for schizophrenia. In 2023, the FDA approved it for Alzheimer’s-related agitation. However, according to Otsuka, its mechanism of action is unknown.

Its efficacy may be mediated through a combination of partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors, antagonist activity at serotonin 5-HT2A receptors, as well as antagonism of alpha-1B/2C receptors, said the company.

Different Biomarker Profiles Identified in Study of Late Dupilumab Responders

Article Type

Fri, 10/18/2024 - 12:09

 

— A proteomics study designed to determine why some patients with atopic dermatitis (AD) respond quickly to dupilumab, others respond more slowly, and the remainder do not respond at all demonstrated that molecular responses in these three groups are very different.

A discovery that could lead to personalizing therapies, the data identified “distinct systemic biomarker profiles,” according to Ester Del Duca, MD, an instructor in the Laboratory of Inflammatory Skin Diseases at the Icahn School of Medicine at Mount Sinai, New York City.

The study was conducted with 67 patients with AD and 16 healthy controls. Serum was collected at two timepoints: An average of 20 weeks after starting dupilumab, then at a mean interval of about 9 months later. At these timepoints, called follow-up 1 and 2, a panel of more than 600 proteins, including unique markers for immunologic, cardiovascular, and neurologic activity, were evaluated.

The criterion for differentiating the three response groups was an Investigator Global Assessment (IGA) score of 0 or 1, signifying clear or almost clear skin (or at least a 2-point IGA reduction from baseline). Early responders were those who met the criterion at both follow-ups, late responders were those who met this criterion only at the second follow-up, and nonresponders never met the criterion.

“There were no significant differences at baseline in clinical severity, past medical history, or patient characteristics,” said Del Duca, who presented these data in a late breaking news session at the European Academy of Dermatology and Venereology (EADV) 2024 Congress.

Of the 67 patients with AD, 39 were early responders, 11 were late responders, and 17 were nonresponders.

The differences in proteomics were marked.
For early responders, there was an early normalization of the proteome, reported Del Duca, illustrating the differences in the proteome of the three groups with a color-coded chart of protein up-regulation and down-regulation relative to healthy controls. The normalization of the proteome persisted in early responders when assessed at the second follow-up.

In the late responders, the proteome dysregulation was substantial relative to healthy controls at the first follow-up, but there was considerable improvement by the second follow-up. Although the change at the second follow-up was still not as robust as that seen in the early responders at either follow-up, Del Duca described the proteomic profile as a 45% improvement from the first follow-up.

In contrast, nonresponders showed worsening in their blood proteome from follow-up 1 to 2. Nonresponders at first follow-up showed up-regulation relative to healthy controls for many proteins associated with the Th1 response, such as interferon gamma, CXCL9, and CXCL10, and Th2 response, such as interleukin-4 and Th17/22, and these did not normalize or worsen by the second follow-up.

“Uniquely to nonresponders, key Th1 biomarkers remained significantly up-regulated relative to controls at both follow-up 1 and 2,” with a P value < .05, Del Duca reported.

To achieve normalization of the proteome as defined by healthy controls, both up-regulation and down-regulation of protein activity were required, although more up-regulations than down-regulations were observed.

When evaluating the proteome changes most implicated in immunoregulation, the investigators were able to show a correlation between worsening in the proteome and greater severity of AD as defined by IGA, Eczema Area and Severity Index, and body surface area involvement.

“Spearman analysis revealed strong and positive correlations between improvements in biomarkers at follow-up 1 and 2 with improvements in clinical markers,” Del Duca said. As examples, she noted favorable changes in biomarkers specifically associated with T cells, dendritic cells, and natural killer cells as clinical outcomes improved.

Conversely, the worsening in T-cell activation among nonresponders, particularly Th1 biomarkers, also tracked with increasing AD symptoms over time.

The implications of the research are broad, and most importantly, it shows that therapeutic targets are likely to differ between patients with AD, according to Del Duca. Although proteomic studies have not yet been conducted with other treatments, these might provide further insight about how patients with AD differ in response across other drugs.

This is important work, according to Brigitte Dréno, MD, PhD, head of the Department of Dermatology, Nantes University Hospital in France. As moderator of the late-breaking news session, she suggested that there are many potential messages from these data, not least that treatment of AD likely involves targeting cytokines beyond those affected by dupilumab in at least some patients.

When Dréno asked Del Duca about what could be surmised about changes from baseline before treatment to the first follow-up, Del Duca said that the study was retrospective, so baseline data were not available.

This is an important missing piece of this investigation, according to Dréno.

“As you move this work forward,” she said that it would be “very important” to determine “if there are predictive markers for evaluating which patients will respond.”

This is a small study with many additional variables to consider in order to develop a clinically useful tool, Del Duca noted. However, this work not only has the potential to guide treatment selection but the biomarkers up-regulated in nonresponders are already “suggesting potential targets for refining therapeutic strategies,” she said.

The study received funding from Bristol-Myers Squibb. Del Duca reported no financial relationships with industry. Dréno reported financial relationships with La Roche–Posay, Pierre Fabré, and Galderma.

State of Confusion: Should All Children Get Lipid Labs for High Cholesterol?

Article Type
Changed
Fri, 10/18/2024 - 11:42

 

Clinicians receive conflicting advice on whether to order blood tests to screen for lipids in children. A new study could add to the confusion. Researchers found that a combination of physical proxy measures such as hypertension and body mass index (BMI) predicted the risk for future cardiovascular events as well as the physical model plus lipid labs, questioning the value of those blood tests.

Some medical organizations advise screening only for high-risk children because more research is needed to define the harms and benefits of universal screening. Diet and behavioral changes are sufficient for most children, and universal screening could lead to false positives and unnecessary further testing, they said.

Groups that favor lipid tests for all children say these measurements detect familial hypercholesterolemia (FH) that would not otherwise be diagnosed, leading to treatment with drugs like statins and a greater chance of preventing cardiovascular disease (CVD) in adulthood.

Researchers from the new study said their findings do not address screenings for FH, which affects 1 in 250 US children and puts them at a risk for atherosclerotic CVD.
 

Recommending Blood Tests in Age Groups

One of the seminal guidelines on screening lipids in children came from the National Heart, Lung, and Blood Institute (NHLBI), which in 2011 recommended children undergo dyslipidemia screening between the ages of 9 and 11 years and again between 17 and 21 years. Children should receive a screening starting at age 2 years if they have a family history of CVD or dyslipidemia or have diabetes, an elevated BMI, or hypertension. The American Academy of Pediatrics shortly followed suit, issuing similar recommendations.

Screening for the two subsets of ages was an expansion from the original 1992 guidelines from the National Cholesterol Education Program, which recommended screening only for children with either a family history of early CVD or elevated total cholesterol levels.

A 2011 panel for the NHLBI said the older approach identified significantly fewer children with abnormal levels of low-density lipoprotein cholesterol (LDL-C) than the addition of two age groups for screening, adding that many children do not have a complete family history. The American College of Cardiology and American Heart Association later supported NHLBI’s stance in their joint guidelines on the management of cholesterol.

Mark Corkins, MD, chair of the AAP’s Committee on Nutrition, told Medscape Medical News that if children are screened only because they have obesity or a family history of FH, some with elevated lipid levels will be missed. For instance, studies indicate caregiver recall of FH often is inaccurate, and the genetic disorder that causes the condition is not related to obesity.

“The screening is to find familial hypercholesterolemia, to try to find the ones that need therapy,” that would not be caught by the risk-based screening earlier on in childhood, Corkins said.
 

Only Screen Children With Risk Factors

But other groups do not agree. The US Preventive Services Task Force (USPSTF) found insufficient evidence to recommend for or against screening for lipid disorders in asymptomatic children and teens.

 

 

The group also said it found inadequate evidence that lipid-lowering interventions in the general pediatric population lead to reductions in cardiovascular events or all-cause mortality once they reached adulthood. USPSTF also raised questions about the safety of lipid-lowering drugs in children.

“The current evidence is insufficient to assess the balance of benefits and harms of screening for lipid disorders in children and adolescents 20 years or younger,” the panel wrote.

The American Academy of Family Physicians supports USPSTF’s recommendations.
 

Low Rate of Screening

While the uncertainty over screening in children continues, the practice has been adopted by a minority of clinicians.

A study published in JAMA Network Open in July found 9% of 700,000 9- to 11-year-olds had a documented result from a lipid screening. Among more than 1.3 million 17- to 21-year-olds, 13% had received a screening.

As BMI went up, so did screening rates. A little over 9% children and teens with a healthy weight were screened compared with 14.7% of those with moderate obesity and 21.9% of those with severe obesity.

Among those screened, 32.3% of 9- to 11-year-olds and 30.2% of 17- to 21-year-olds had abnormal lipid levels, defined as having one elevated measure out of five, including total cholesterol of 200 mg/dL or higher or LDL-C levels of 130 mg/dL or higher.

Justin Zachariah, MD, MPH, an associate professor of pediatrics-cardiology at Baylor College of Medicine in Houston, spoke about physicians screening children based only on factors like obesity during a presentation at the recent annual meeting of the American Academy of Pediatrics. He cited research showing roughly one in four children with abnormal lipids had a normal weight.

If a clinician is reserving a lipid screening for a child who is overweight or has obesity, “you’re missing nearly half the problem,” Zachariah said during his presentation.

One reason for the low rate of universal screening may be inattention to FH by clinicians, according to Samuel S. Gidding, MD, a professor in the Department of Genomic Health at Geisinger College of Health Sciences in Bridgewater Corners, Vermont.

For instance, a clinician has only a set amount of time during a well-child visit and other issues may take precedence, “so it doesn’t make sense to broach preventive screening for something that could happen 30 or 40 years from now, vs this [other] very immediate problem,” he said.

Clinicians “are triggered to act on the LDL level, but don’t think about FH as a possible diagnosis,” Gidding told Medscape Medical News.

Another barrier is that in some settings, caregivers must take children and teens to another facility on a different day to fulfill an order for a lipid test.

“It’s reluctance of doctors to order it, knowing patients won’t go through with it,” Gidding said.

Clinicians receive conflicting advice on whether to order blood tests to screen for lipids in children. A new study could add to the confusion. Researchers found that a combination of physical proxy measures such as hypertension and body mass index (BMI) predicted the risk for future cardiovascular events as well as the physical model plus lipid labs, questioning the value of those blood tests.

Some medical organizations advise screening only for high-risk children because more research is needed to define the harms and benefits of universal screening. Diet and behavioral changes are sufficient for most children, and universal screening could lead to false positives and unnecessary further testing, they said.

Groups that favor lipid tests for all children say these measurements detect familial hypercholesterolemia (FH) that would not otherwise be diagnosed, leading to treatment with drugs like statins and a greater chance of preventing cardiovascular disease (CVD) in adulthood.

Researchers from the new study said their findings do not address screenings for FH, which affects 1 in 250 US children and puts them at a risk for atherosclerotic CVD.
 

Recommending Blood Tests in Age Groups

One of the seminal guidelines on screening lipids in children came from the National Heart, Lung, and Blood Institute (NHLBI), which in 2011 recommended children undergo dyslipidemia screening between the ages of 9 and 11 years and again between 17 and 21 years. Children should receive a screening starting at age 2 years if they have a family history of CVD or dyslipidemia or have diabetes, an elevated BMI, or hypertension. The American Academy of Pediatrics shortly followed suit, issuing similar recommendations.

Screening for the two subsets of ages was an expansion from the original 1992 guidelines from the National Cholesterol Education Program, which recommended screening only for children with either a family history of early CVD or elevated total cholesterol levels.

A 2011 panel for the NHLBI said the older approach identified significantly fewer children with abnormal levels of low-density lipoprotein cholesterol (LDL-C) than the addition of two age groups for screening, adding that many children do not have a complete family history. The American College of Cardiology and American Heart Association later supported NHLBI’s stance in their joint guidelines on the management of cholesterol.

Mark Corkins, MD, chair of the AAP’s Committee on Nutrition, told Medscape Medical News that if children are screened only because they have obesity or a family history of FH, some with elevated lipid levels will be missed. For instance, studies indicate caregiver recall of FH often is inaccurate, and the genetic disorder that causes the condition is not related to obesity.

“The screening is to find familial hypercholesterolemia, to try to find the ones that need therapy,” that would not be caught by the risk-based screening earlier on in childhood, Corkins said.
 

Only Screen Children With Risk Factors

But other groups do not agree. The US Preventive Services Task Force (USPSTF) found insufficient evidence to recommend for or against screening for lipid disorders in asymptomatic children and teens.

 

 

The group also said it found inadequate evidence that lipid-lowering interventions in the general pediatric population lead to reductions in cardiovascular events or all-cause mortality once they reached adulthood. USPSTF also raised questions about the safety of lipid-lowering drugs in children.

“The current evidence is insufficient to assess the balance of benefits and harms of screening for lipid disorders in children and adolescents 20 years or younger,” the panel wrote.

The American Academy of Family Physicians supports USPSTF’s recommendations.
 

Low Rate of Screening

While the uncertainty over screening in children continues, the practice has been adopted by a minority of clinicians.

A study published in JAMA Network Open in July found 9% of 700,000 9- to 11-year-olds had a documented result from a lipid screening. Among more than 1.3 million 17- to 21-year-olds, 13% had received a screening.

As BMI went up, so did screening rates. A little over 9% children and teens with a healthy weight were screened compared with 14.7% of those with moderate obesity and 21.9% of those with severe obesity.

Among those screened, 32.3% of 9- to 11-year-olds and 30.2% of 17- to 21-year-olds had abnormal lipid levels, defined as having one elevated measure out of five, including total cholesterol of 200 mg/dL or higher or LDL-C levels of 130 mg/dL or higher.

Justin Zachariah, MD, MPH, an associate professor of pediatrics-cardiology at Baylor College of Medicine in Houston, spoke about physicians screening children based only on factors like obesity during a presentation at the recent annual meeting of the American Academy of Pediatrics. He cited research showing roughly one in four children with abnormal lipids had a normal weight.

If a clinician is reserving a lipid screening for a child who is overweight or has obesity, “you’re missing nearly half the problem,” Zachariah said during his presentation.

Hidradenitis Suppurativa: Nodules Respond to As Needed Topical JAK Inhibitor

Article Type
Changed
Fri, 10/18/2024 - 11:36

 

— Following the report of results from a randomized trial in which a topically applied Janus kinase (JAK) inhibitor was highly active in patients with mild to moderate hidradenitis suppurativa (HS), an open-label extension showed that 16 more weeks of treatment on as-needed basis provided complete or near complete clearance of lesions in up to 38.5% of patients.

“Ruxolitinib cream may be a novel approach to address an unmet medical need in the treatment of milder HS for which there are no currently approved treatments,” reported Martina L. Porter, MD, assistant professor of dermatology, Harvard Medical School, and Beth Israel Deaconess Medical Center, both in Boston, Massachusetts.

In the earlier 16-week, double-blind, randomized period of this phase 2b study, 69 adults with mild to moderate HS were randomized to 1.5% ruxolitinib cream or vehicle, applied twice daily for 16 weeks. The new results are from the open-label extension period, where those on the vehicle were crossed over to topical ruxolitinib and treatment was continued for another 16 weeks.
 

Over 80% Meet Primary Endpoint at 32 Weeks

Entry criteria for the study included Hurley stage I or II HS with no draining tunnels. Hurley stage III patients were not eligible. Patients had to have an abscess or inflammatory nodule (AN) count of 3 lesions concentrated in a single anatomic area or up to 10 lesions if disseminated. The median AN count of those enrolled was 5.4. 

In the randomized portion of the study and in the open-label extension, the recommendation for application was to apply the medication to nodules and a 1-cm area of surrounding skin. As-needed treatment was only recommended in the extension portion of the study and rescue medication was not allowed.

The goal of the open-label extension was to evaluate how long the improvements were sustained, according to Dr. Porter, who presented the results at the 2024 European Academy of Dermatology and Venereology (EADV) meeting.

The primary endpoints of AN50, signaling at least a 50% reduction in AN count from baseline, among those initially randomized to ruxolitinib cream climbed slightly from 79.2% at the end of 16 weeks to 81.0% at the end of 32 weeks.

This shows that the benefits recorded in the randomized phase of the trial were sustained during the open-label extension, Dr. Porter said. 

For those randomized to vehicle, there was a substantial response of 56.3% for AN50 during the randomized portion of the study, but catchup in the vehicle group to those on active therapy occurred rapidly over the open-label extension. By the end of 32 weeks, the score among the crossover patients slightly exceeded that of those on continuous therapy (88.5% vs 81.0%).

AN75 responses at week 32 were 66.7% and 61.5% in the continuous arm and crossover arm, respectively. The proportion of patients reaching an AN90 or AN100 response, meaning clear or almost clear, were 19% and 38.5%, in continuous treatment and crossover arms, respectively.

One of the secondary endpoints was the HS Clinical Response 50, indicating at least a 50% reduction in the AN count with no increase in abscesses or draining fistulae. At 32 weeks, the proportions of patients who met this endpoint were 81.0% and 88.5% in the continuous treatment and crossover arms, respectively. 

The mean reduction in International HS Severity Scoring System scores from baseline were 4.1 and 4.5 in the continuous treatment and crossover arms, respectively. 
 

Patients in the Study Mostly Women, 42% Black Individuals

Most (94%) of the participants were women; about 45% and 42% were White and Black individuals, respectively. Most of the remaining patients were Asian individuals. The median age at entry was 29 years, and the mean body mass index was approximately 34 kg/m2. A substantial proportion of patients had systemic comorbidities, according to Dr. Porter, who noted that about 25% had anxiety, depression, or both.

“This phenotype — a high proportion of women with nodules but no draining tunnels and a substantial number of comorbidities — is one we often see in patients with mild HS,” Dr. Porter said.

The safety and tolerability profile of ruxolitinib cream was quite good, according to Dr. Porter, who noted that there were fewer treatment-related adverse events in the open-label extension. Overall, the number of treatment-related adverse events (3.6%), including application site reactions leading to discontinuation (1.8%) was low. 

Although there is a growing list of therapies now approved for HS, Dr. Porter emphasized that all have been developed for moderate to severe disease. She suggested that there is a sizable group of patients with mild disease for whom such therapies as biologics might not be warranted even if symptom relief is needed.

Given this unmet need, she said phase 3 trials are warranted to confirm the benefits and the safety of a topical therapy that can be used as needed to control intermittent HS flares.

Asked to comment, the lead author of a recently published review article on the “evolving treatment landscape” of HS, James G. Krueger, MD, professor in clinical investigation at Rockefeller University, New York City, agreed that there is an unmet need for effective and safe therapies in milder HS.

“I agree with the premise,” said Dr. Krueger, indicating that phase 3 data will be essential to confirm the promise of this approach. Dr. Krueger, who did not hear the results presented at the EADV meeting, listed several JAK inhibitors in his review that have shown promising efficacy as oral agents and support JAK signaling as a target of HS treatment. 

Topical ruxolitinib (Opzelura) is currently approved in the United States for treating nonsegmental vitiligo in patients aged ≥ 12 years and for mild to moderate atopic dermatitis in patients aged ≥ 12 years. In Europe, it is approved for treatment of nonsegmental vitiligo with facial involvement in patients aged ≥ 12 years. 

Dr. Porter reported no potential conflicts of interest. Dr. Krueger reported financial relationships with more than 25 pharmaceutical companies not including Incyte, which is developing ruxolitinib cream.

AHA Scientific Statement Links Three Common Cardiovascular Diseases to Cognitive Decline, Dementia

Article Type
Changed
Tue, 10/22/2024 - 09:02

 

The American Heart Association (AHA) has issued a new scientific statement on the link between heart failure, atrial fibrillation, and coronary heart disease and the increased risk for cognitive impairment and dementia.

The statement includes an extensive research review and offers compelling evidence of the inextricable link between heart health and brain health, which investigators said underscores the benefit of early intervention.

The cumulative evidence “confirms that the trajectories of cardiac health and brain health are inextricably intertwined through modifiable and nonmodifiable factors,” the authors wrote.

Investigators say the findings reinforce the message that addressing cardiovascular health early in life may deter the onset or progression of cognitive impairment later on.

And the earlier this is done, the better, said lead author Fernando D. Testai, MD, PhD, a professor of neurology and the vascular neurology section head, Department of Neurology and Rehabilitation, University of Illinois, Chicago.

The statement was published online in Stroke.
 

Bridging the Research Gap

It’s well known that there’s a bidirectional relationship between heart and brain function. For example, heart failure can lead to decreased blood flow that can damage the brain, and stroke in some areas of the brain can affect the heart.

However, that’s only part of the puzzle and doesn’t address all the gaps in the understanding of how cardiovascular disease contributes to cognition, said Testai.

“What we’re trying to do here is to go one step further and describe other connections between the heart and the brain,” he said.

Investigators carried out an extensive PubMed search for heart failure, atrial fibrillation, and coronary heart disease. Researchers detailed the frequency of each condition, mechanisms by which they might cause cognitive impairment, and prospects for prevention and treatment to maintain brain health.

A recurring theme in the paper is the role of inflammation. Evidence shows there are “remarkable similarities in the inflammatory response that takes place,” with both cardiac disease and cognitive decline, said Testai.

Another potential shared mechanism relates to biomarkers, particularly amyloid, which is strongly linked to Alzheimer’s disease.

“But some studies show amyloid can also be present in the heart, especially in patients who have decreased ejection fraction,” said Testai.
 

Robust Heart-Brain Connection

The statement’s authors collected a substantial amount of evidence showing vascular risk factors such as hypertension and diabetes “can change how the brain processes and clears up amyloid,” Testai added.

The paper also provides a compilation of evidence of shared genetic predispositions when it comes to heart and brain disorders.

“We noticed that some genetic signatures that have historically been associated with heart disease seem to also correlate with structural changes in the brain. That means that at the end of the day, some patients may be born with a genetic predisposition to developing both conditions,” said Testai.

This indicates that the link between the two organs “begins as early as conception” and underscores the importance of adopting healthy lifestyle habits as early as possible, he added.

“That means you can avoid bad habits that eventually lead to hypertension, diabetes, and cholesterol, that eventually will lead to cardiac disease, which eventually will lead to stroke, which eventually will lead to cognitive decline,” Testai noted.

However, cardiovascular health is more complicated than having good genes and adhering to a healthy lifestyle. It’s not clear, for example, why some people who should be predisposed to developing heart disease do not develop it, something Testai refers to as enhanced “resilience.”

For example, Hispanic or Latino patients, who have relatively poor cardiovascular risk factor profiles, seem to be less susceptible to developing cardiac disease.
 

More Research Needed

While genetics may partly explain the paradox, Testai believes other protective factors are at play, including strong social support networks.

Testai referred to the AHA’s “Life’s Essential 8” — the eight components of cardiovascular health. These include a healthy diet, participation in physical activity, nicotine avoidance, healthy sleep, healthy weight, and healthy levels of blood lipids, blood glucose, and blood pressure.

More evidence is needed to show that effective management of cardiac disease positively affects cognition. Currently, cognitive measures are rarely included in studies examining various heart disease treatments, said Testai.

“There should probably be an effort to include brain health outcomes in some of the cardiac literature to make sure we can also measure whether the intervention in the heart leads to an advantage for the brain,” he said.

More research is also needed to determine whether immunomodulation has a beneficial effect on the cognitive trajectory, the statement’s authors noted.

They point out that the interpretation and generalizability of the studies described in the statement are confounded by disparate methodologies, including small sample sizes, cross-sectional designs, and underrepresentation of Black and Hispanic individuals.
 

‘An Important Step’

Reached for a comment, Natalia S. Rost, MD, Chief of the Stroke Division at Massachusetts General Hospital and professor of neurology at Harvard Medical School, both in Boston, said this paper “is an important step” in terms of pulling together pertinent information on the topic of heart-brain health.

She praised the authors for gathering evidence on risk factors related to atrial fibrillation, heart failure, and coronary heart disease, which is “the part of the puzzle that is controllable.”

This helps reinforce the message that controlling vascular risk factors helps with brain health, said Rost.

But brain health is “much more complex than just vascular health,” she said. It includes other elements such as freedom from epilepsy, migraine, traumatic brain injury, and adult learning disabilities.

No relevant conflicts of interest were disclosed.

The American Heart Association (AHA) has issued a new scientific statement on the link between heart failure, atrial fibrillation, and coronary heart disease and the increased risk for cognitive impairment and dementia.

The statement includes an extensive research review and offers compelling evidence of the inextricable link between heart health and brain health, which investigators said underscores the benefit of early intervention.

The cumulative evidence “confirms that the trajectories of cardiac health and brain health are inextricably intertwined through modifiable and nonmodifiable factors,” the authors wrote.

Investigators say the findings reinforce the message that addressing cardiovascular health early in life may deter the onset or progression of cognitive impairment later on.

And the earlier this is done, the better, said lead author Fernando D. Testai, MD, PhD, a professor of neurology and the vascular neurology section head, Department of Neurology and Rehabilitation, University of Illinois, Chicago.

The statement was published online in Stroke.
 

Bridging the Research Gap

It’s well known that there’s a bidirectional relationship between heart and brain function. For example, heart failure can lead to decreased blood flow that can damage the brain, and stroke in some areas of the brain can affect the heart.

However, that’s only part of the puzzle and doesn’t address all the gaps in the understanding of how cardiovascular disease contributes to cognition, said Testai.

“What we’re trying to do here is to go one step further and describe other connections between the heart and the brain,” he said.

ACOG Updates Breast Cancer Screening Guidelines

Article Type
Changed
Wed, 11/06/2024 - 05:28

 

The American College of Obstetricians and Gynecologists (ACOG) has updated its breast cancer screening guidelines, recommending that individuals at an average risk for breast cancer initiate mammography screening at age 40. This change reflects evolving evidence that starting earlier screening yields greater net benefits in reducing breast cancer mortality, particularly for certain racial groups with higher risk factors.

Breast cancer is the second leading cause of cancer deaths in American women overall and the leading cause of cancer deaths among Black and Hispanic women. Although mammography has long been recognized as a life-saving tool by detecting cancer early, there has been debate on when screening should begin due to concerns about overdiagnosis, false positives, and potential harms such as unnecessary biopsies.

Recent evidence has prompted ACOG to revise its recommendation for individuals assigned female at birth, including cisgender women, transgender men, and nonbinary individuals. This updated guidance includes individuals with dense breast tissue or a family history of breast cancer but excludes those with higher risk factors, such as a personal history of breast cancer or previous high-risk lesion on a breast biopsy, genetic mutations linked to higher cancer risk, or a history of high-dose radiation therapy to their chest at a young age.

Under the new guidelines, routine screening mammography should start at age 40 and can be performed annually or every 2 years, based on an informed, shared decision-making process that considers the benefits and potential harms of frequent screening.

Previously, ACOG recommended initiating screening between ages 40 and 50, depending on individual risk factors and preferences, with screening required by age 50 at the latest. However, several factors, including an increasing incidence of breast cancer in younger women, have influenced the decision to lower the recommended starting age.
 

Increasing Incidence Among Younger Women

Between 2015 and 2019, the incidence of invasive breast cancer in women aged 40-49 years increased by approximately 2% per year.

“There has been a concerning trend of increasing breast cancer diagnoses among women in their 40s, and new data shows that earlier screening could make a significant difference in decreasing breast cancer deaths,” said Eve Zaritsky, MD, FACOG, coauthor of the clinical practice update. “While screening can sometimes cause anxiety for people and even unnecessary follow-up, the benefits of diagnosing breast cancer earlier outweigh those risks enough to warrant starting to get mammograms at age 40.”

Studies commissioned by the US Preventive Services Task Force (USPSTF) show that starting mammography at age 40 provides a greater overall benefit than beginning at age 50. Early screening reduces the number of breast cancer deaths and increases life years gained when weighed against the harms of false positives, overdiagnosis, and benign biopsies.
 

Addressing Health Inequities

The benefits of earlier screening are expected to be particularly significant for Black women, who have disproportionately high mortality rates from breast cancer. Even though Black women have a lower overall incidence of breast cancer than White women, they have a 40% higher 5-year age-adjusted mortality rate from the disease and a 45% increased incidence of invasive breast cancer before age 50. Black women are also more likely to be diagnosed with aggressive subtypes, such as triple-negative breast cancer, which is harder to detect and treat and occurs at younger ages.

 

 

Racial disparities in breast cancer outcomes are deeply rooted in inequities in social determinants of health, such as access to care, housing, and environmental conditions. Black women are also less likely to receive timely or comprehensive treatment than White women, which contributes to worse survival rates even after adjusting for socioeconomic factors and insurance status.

“Our updated recommendation addresses important inequities in breast cancer diagnosis, treatment, and death, and we hope that the earlier initiation of mammography screening across the board will have a great net benefit in outcomes for Black women especially, who have been shown to have the poorest outcomes when it comes to breast cancer, in part because of long-standing inequities in social determinants of health,” added coauthor Cherie C. Hill, MD, FACOG.

ACOG’s updated recommendation aligns with that of other leading organizations, including the USPSTF, the National Comprehensive Cancer Network, the American College of Radiology, and the Society of Breast Imaging. This growing consensus among experts is expected to reduce confusion among clinicians and patients regarding when to begin screening, thus improving screening rates in individuals in the 40- to 49-year age group.

Zaritsky and Hill reported no conflicts of interest.

Exocrine Pancreatic Insufficiency: Optimal PERT Dose Varies by Primary Pancreatic Disease

Article Type
Changed
Fri, 10/18/2024 - 10:34

 

The appropriate dose of pancreatic enzyme replacement therapy (PERT) for exocrine pancreatic insufficiency (EPI) depends on the root cause of the insufficiency, according to results of a prospective study using European registry data. 

Specifically, patients with EPI caused by pancreatic cancer or pancreatectomy need significantly more enzyme replacement than patients with insufficiency caused by chronic pancreatitis and acute pancreatitis. The need to add a proton pump inhibitor (PPI) to achieve the therapeutic goal also varies by condition, the study showed. 

World Pancreatic Cancer Coalition
Dr. Enrique Domínguez Muñoz

One of the main symptoms of EPI is malnutrition, and successful PERT is defined as the resolution of nutritional deficiencies and relief of symptoms and signs associated with insufficiency, said study lead Enrique Domínguez Muñoz, MD, director of the department of gastroenterology and hepatology at University Hospital of Santiago de Compostela, Spain. 

Our findings show that, “in order to achieve this, enzyme dose escalation and sometimes additional treatment with a [PPI] should be applied as required by the individual”, he reported in a presentation at the United European Gastroenterology (UEG) Week 2024.

Therefore, having dose recommendations for PERT for different causes of EPI is very helpful, said Domínguez Muñoz.

Pancreatic enzyme preparations, specifically pancreatin, are the recommended first-line treatment for EPI, but the initial doses of PERT vary depending on the patient’s age (whether adult or child), the severity of the insufficiency, and the fat content of the meal eaten. 

Domínguez Muñoz and colleagues wanted to explore whether — and how — the severity of EPI varied with different diseases, therefore varying the optimal dose of PERT. 
 

Optimal Dosing to Achieve Therapeutic Goal 

The prospective study drew on data from a European multicenter registry of patients diagnosed with EPI being treated with PERT in expert centers. 

The researchers evaluated the dose of PERT required to achieve symptom relief and normalization of the nutritional status in adult patients with EPI secondary to different pancreatic diseases and conditions. The percentage of patients who required the addition of a PPI to PERT to achieve the therapeutic goal was also determined. 

Decisions on the initial enzyme dose (including the addition of a PPI) and any necessary adjustments during follow-up to achieve the therapeutic goal were made by the participants’ clinicians.

A total of 678 patients (mean age, 61.2 ± 13.8 years; 63.6% male) were stratified according to disease: 50% had chronic pancreatitis, 10% had acute pancreatitis, 17% had undergone pancreaticoduodenectomy, 15% had pancreatic cancer, and 8% had another pancreatic condition. 

To achieve the therapeutic goal, the median optimal enzyme doses with the main meal for patients with acute pancreatitis, chronic pancreatitis, pancreatic cancer, and pancreaticoduodenectomy, were 40,000, 50,000, 70,000, and 75,000 Ph.U, respectively. The respective optimal daily enzyme doses were 100,000, 150,000, 210,000, and 225,000 Ph.U. 

The highest enzyme doses required with the main meal to achieve the therapeutic goal for patients with acute pancreatitis, chronic pancreatitis, pancreatic cancer, and pancreaticoduodenectomy were 125,000, 210,000, 175,000, and 210,000 Ph.U, respectively. The respective highest daily enzyme doses were 400,000, 625,000, 675,000, and 750,000 Ph.U. 

The need for additional therapy with twice-daily PPI to achieve the therapeutic goal also varied according to the underlying disease. It was administered to 44.1% of patients with acute pancreatitis, 37.2% of patients with chronic pancreatitis, 78.8% of patients with pancreatic cancer, and 74.1% of patients who had undergone pancreaticoduodenectomy. 

“This shows us that sometimes we really do need to significantly increase the dose of pancreatic enzyme replacement therapy,” reported Domínguez Muñoz. 
 

Clear Direction on Where to Start

Comoderator Kasper Overbeek, MD, from the department of gastroenterology and hepatology, Erasmus MC Cancer Institute, University Medical Center, the Netherlands, commented: “It’s a useful study because it gives us practical advice on what to do in specific cases.”

Until now, we’ve done the same thing for everyone, he said, “but these data clearly show that this is not optimal.” 

In addition, “it is often the case with enzyme replacement therapy that doctors under-dose so it is necessary to increase the dose,” he said.

“This work gives us a clearer direction on where to start,” Overbeek said. “For example, with patients who have cancer, because they do not have time to start low and titrate up, they need a higher dose than patients with chronic pancreatitis.”

This pragmatic and novel guidance will “help us in our clinical practice,” he added.

Domínguez Muñoz and colleagues wanted to explore whether — and how — the severity of EPI varied with different diseases, therefore varying the optimal dose of PERT. 
 

Optimal Dosing to Achieve Therapeutic Goal 

The prospective study drew on data from a European multicenter registry of patients diagnosed with EPI being treated with PERT in expert centers. 

The researchers evaluated the dose of PERT required to achieve symptom relief and normalization of the nutritional status in adult patients with EPI secondary to different pancreatic diseases and conditions. The percentage of patients who required the addition of a PPI to PERT to achieve the therapeutic goal was also determined. 

Decisions on the initial enzyme dose (including the addition of a PPI) and any necessary adjustments during follow-up to achieve the therapeutic goal were made by the participants’ clinicians.

A total of 678 patients (mean age, 61.2 ± 13.8 years; 63.6% male) were stratified according to disease: 50% had chronic pancreatitis, 10% had acute pancreatitis, 17% had undergone pancreaticoduodenectomy, 15% had pancreatic cancer, and 8% had another pancreatic condition. 

To achieve the therapeutic goal, the median optimal enzyme doses with the main meal for patients with acute pancreatitis, chronic pancreatitis, pancreatic cancer, and pancreaticoduodenectomy, were 40,000, 50,000, 70,000, and 75,000 Ph.U, respectively. The respective optimal daily enzyme doses were 100,000, 150,000, 210,000, and 225,000 Ph.U. 

The highest enzyme doses required with the main meal to achieve the therapeutic goal for patients with acute pancreatitis, chronic pancreatitis, pancreatic cancer, and pancreaticoduodenectomy were 125,000, 210,000, 175,000, and 210,000 Ph.U, respectively. The respective highest daily enzyme doses were 400,000, 625,000, 675,000, and 750,000 Ph.U. 

The need for additional therapy with twice-daily PPI to achieve the therapeutic goal also varied according to the underlying disease. It was administered to 44.1% of patients with acute pancreatitis, 37.2% of patients with chronic pancreatitis, 78.8% of patients with pancreatic cancer, and 74.1% of patients who had undergone pancreaticoduodenectomy. 

“This shows us that sometimes we really do need to significantly increase the dose of pancreatic enzyme replacement therapy,” reported Domínguez Muñoz. 
 

Clear Direction on Where to Start

Comoderator Kasper Overbeek, MD, from the department of gastroenterology and hepatology, Erasmus MC Cancer Institute, University Medical Center, the Netherlands, commented: “It’s a useful study because it gives us practical advice on what to do in specific cases.”

Until now, we’ve done the same thing for everyone, he said, “but these data clearly show that this is not optimal.” 

In addition, “it is often the case with enzyme replacement therapy that doctors under-dose so it is necessary to increase the dose,” he said.

“This work gives us a clearer direction on where to start,” Overbeek said. “For example, with patients who have cancer, because they do not have time to start low and titrate up, they need a higher dose than patients with chronic pancreatitis.”

This pragmatic and novel guidance will “help us in our clinical practice,” he added.

The appropriate dose of pancreatic enzyme replacement therapy (PERT) for exocrine pancreatic insufficiency (EPI) depends on the root cause of the insufficiency, according to results of a prospective study using European registry data. 

Specifically, patients with EPI caused by pancreatic cancer or pancreatectomy need significantly more enzyme replacement than patients with insufficiency caused by chronic pancreatitis and acute pancreatitis. The need to add a proton pump inhibitor (PPI) to achieve the therapeutic goal also varies by condition, the study showed.

One of the main symptoms of EPI is malnutrition, and successful PERT is defined as the resolution of nutritional deficiencies and relief of symptoms and signs associated with insufficiency, said study lead Enrique Domínguez Muñoz, MD, director of the department of gastroenterology and hepatology at University Hospital of Santiago de Compostela, Spain. 

Our findings show that, “in order to achieve this, enzyme dose escalation and sometimes additional treatment with a [PPI] should be applied as required by the individual”, he reported in a presentation at the United European Gastroenterology (UEG) Week 2024.

Therefore, having dose recommendations for PERT for different causes of EPI is very helpful, said Domínguez Muñoz.

At Last, Treatment Is in Sight for Charcot-Marie-Tooth Disease

Article Type
Changed
Thu, 10/17/2024 - 15:03

— There’s no medical treatment for Charcot-Marie-Tooth (CMT) disease, a debilitating neurologic disorder that’s both progressive and incurable. But now, nerve specialists learned, new potential treatments are moving closer to clinical trials.

Genetic-based therapies for CMT are currently in preclinical research phases, and an experimental small-molecule drug has reached phase 3 in humans, neurologists told an audience at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024. But the neurologists also noted challenges, such as determining the best way to track disease progression — which can be slow — and the need to recruit high numbers of patients for trials.
 

A Common Genetic Neuromuscular Disorder

As Mario Saporta, MD, PhD, MBA, of the University of Miami, Coral Gables, Florida, explained, CMT is the most common genetic neuromuscular disorder, affecting 1 in 2500 people or about 130,000-150,000 in the United States. “Typically, it’s a length-dependent neuropathy, where your longest nerves would be affected earlier and more severely. That’s why we see foot deformities, inverted champagne bottle legs, and hand atrophy.”

Most patients with CMT in the United States have type 1A, which is linked to duplication of the PMP22 gene. All types lead to axonal degeneration, which appears to be the main cause of functional disability, Saporta said. “Patients become weaker and then progress with time, following the degree of axonal generation that they have.”

As many as 150 genes may eventually be deemed to cause CMT. The high number of genetically different forms makes diagnosis and genetic therapy difficult, he said, but that’s just part of the picture. Variations among mutations mean there’s “probably actually over 1000 different diseases” within CMT from a biologic perspective.
 

Genetic Therapy

In regard to genetic treatment, Bipasha Mukherjee-Clavin, MD, PhD, of Johns Hopkins University School of Medicine, Baltimore, Maryland, said a key factor is whether the patient’s form of CMT is passed on in an autosomal dominant or autosomal recessive manner.

“Autosomal dominant conditions are typically caused by gain of function mutations. So that means the goal of our genetic therapeutic would be to reduce expression of the mutated gene,” she said. “In contrast, autosomal recessive conditions are caused by loss-of-function mutations, which means the goal of our genetic therapeutic would be to replace the mutated gene with a normal, wild-type copy.”

A tool like CRISPR could be used to directly edit the part of the genome with a CMT-causing mutation or a viral vector could deliver a healthy, wild-type copy of a gene, she said. These approaches are both being tested.

Another approach is to reduce expression at the RNA level. “RNA therapeutics are FDA [Food and Drug Administration]–approved for other neuromuscular indications, and you may well be using some of these in your own clinical practice,” she said.

Currently, about seven different projects are in the works on the RNA therapeutics front in CMT, she said, including six focusing on type 1A. Mukherjee-Clavin believes that this subtype is a “great” target because it’s so common, affecting an estimated 1 in 5000 people.

“You actually have enough patients to power a clinical trial,” she said. Also, “it’s a homogeneous population, both in terms of the genetics and in terms of the clinical presentation.”
 

 

 

Preclinical Treatment Approaches

However, there are challenges. Drug delivery to Schwann cells, which insulate axons, is difficult, she said. “The other problem is that we want to avoid overly silencing PMP22 because that runs the theoretical risk of causing a different condition, HNPP [hereditary neuropathy with liability to pressure palsies]. HNPP is caused by deletions of PMP22, so we want to avoid that situation.”

Mukherjee-Clavin highlighted two RNA therapeutic products that she expects to move from preclinical to clinical research soon.

One is TVR110 by Armatus Bio, a microRNA intrathecal injection product, which aims to reduce PMP22 overexpression. “It targets basically reduces PMP22 mRNA expression and then normalizes the amount of PMP22 protein that is ultimately generated,” she said.

The other therapy, a small interfering RNA intravenous product delivered to Schwann cells, is being developed by DTx Pharma/Novartis.

Outside of the RNA arena, “there are a number of other programs that are in the preclinical phases that I think will be moving through this pipeline,” Mukherjee-Clavin said. “We’ll see if some of these enter first-in-human clinical trials.”

Meanwhile, Saporta highlighted small-molecule strategies that target a subtype of CMT called sorbitol dehydrogenase (SORD) deficiency that’s caused by mutations in the SORD gene. He noted that Applied Therapeutics is testing an investigational drug called govorestat (AT-007) in 56 patients in a double-blind, randomized, placebo-controlled phase 3 registrational study. The company recently reported that interim 12-month results are promising.

Saporta disclosed consulting for DTx Pharma/Novartis, Applied Therapeutics, and Pharnext. Mukherjee-Clavin had no disclosures.

Genetic Marker Tied to Severe Ulcerative Colitis Identified

Article Type
Changed
Thu, 10/17/2024 - 14:10

 

TOPLINE:

Individuals with ulcerative colitis (UC) who carry the HLA-DRB1*01:03 allele are at increased risk of having a more severe disease course requiring major surgery, hospitalization, and high-dose systemic corticosteroids within 3 years of diagnosis, according to a Danish study.

METHODOLOGY:

  • Reliable biomarkers are lacking to identify patients with inflammatory bowel disease at greater risk for severe disease and who therefore might require intensified monitoring and treatment.
  • Researchers explored genetic variants associated with severe UC in patients from two Danish cohorts, whose DNA was extracted from dried blood spots and full blood, with genotyping then performed to assess the presence of human leukocyte antigen (HLA) alleles and single-nucleotide variants.
  • Severe UC was defined as having at least one major UC-related operation, at least two UC-related hospitalizations exceeding 2 days, and/or use of at least 5000 mg of systemic corticosteroids within 3 years of diagnosis. Patients not meeting these criteria were considered to have less severe UC and included as the comparison group.
  • A genome-wide association study was conducted comparing severe vs less severe UC.

TAKEAWAY:

  • Researchers analyzed 4491 patients with UC (mean age at diagnosis, 23 years; 53% women; 27% with severe UC) and determined that carriers of the HLA-DRB1*01:03 allele had a significantly higher risk for severe UC (odds ratio, 3.32).
  • Compared with noncarriers, those with this allele had an approximately sixfold increased risk of needing major surgery, a fivefold increased risk of requiring at least two hospitalizations, and a twofold increased risk for use of over 5000 mg of systemic corticosteroids within 3 years of diagnosis.
  • Time-to-event analysis showed that the association between carriers and disease severity extended beyond 3 years after diagnosis.
  • Compared with noncarriers, those with the HLA-DRB1*01:03 allele had a higher hazard ratio for time to hospitalization, major surgery, and first treatment with systemic corticosteroids.

IN PRACTICE:

“Although HLA-DRB1*01:03 is a low-frequency allele, carriers have a significantly higher risk of severe ulcerative colitis. Given the low cost of typing a single HLA allele, HLA-DRB1*01:03 could be a valuable tool for risk assessment of patients with ulcerative colitis at diagnosis,” the authors concluded.

SOURCE:

The study, with first author Marie Vibeke Vestergaard, MSc, Aalborg University, Aalborg, Denmark, was published online on October 15 in JAMA, to coincide with its presentation at United European Gastroenterology (UEG) Week 2024 in Vienna, Austria. 

LIMITATIONS:

The findings are based on a Danish population of European genetic ancestry and require validation in diverse patient cohorts with UC.

DISCLOSURES:

The study was funded by the Danish National Research Foundation, the Lundbeck Foundation, and the Novo Nordisk Foundation. The authors reported no relevant disclosures related to the study.
