WASHINGTON – Atopic dermatitis (AD) in childhood presents most commonly by age 1 and typically begins on the face, and while it can make infants “miserable,” caregiver and provider concerns about treatment on the face and at such a young age mean it is often “woefully undertreated,” Robert Sidbury, MD, MPH, said at the annual Revolutionizing Atopic Dermatitis conference.

Identifying and mitigating triggers – such as irritation, contact allergy, and infection – is a cornerstone of treatment in infants, but tailored therapy with topical corticosteroids, topical calcineurin inhibitors (TCIs), and topical phosphodiesterase 4 (PDE4) inhibitors also have roles to play, said Dr. Sidbury, chief of dermatology at Seattle Children’s Hospital and professor in the department of pediatrics at the University of Washington, Seattle.

Views on the use of dupilumab as a systemic agent for severe infantile AD, meanwhile, have shifted significantly in the past year with the Food and Drug Administration approval of the biologic for children aged 6 months to 5 years and with extended experience with the biologic in all ages, including children, Lawrence F. Eichenfield, MD, professor of dermatology and pediatrics at the University of California, San Diego, said at the meeting.

The pediatric dermatologists spoke during a session devoted to AD in infants, during which the diagnosis of AD and the role – and risks – of food allergy testing were also discussed. Diagnosis, said Elaine C. Siegfried, MD, who also spoke during the session, requires careful consideration of mimicking conditions and a broader list of differential diagnoses in those infants with poor growth or frequent infections.

Here are some of the experts’ pearls for practice.
 

Diagnosing AD in infants

Among infants who are growing well and otherwise healthy, the infantile eczema phenotype encompasses AD, seborrheic dermatitis, contact dermatitis, psoriasis – and overlap of more than one of these conditions. “Overlap is common,” said Dr. Siegfried, professor of pediatrics and dermatology at Saint Louis University, and director of the division of pediatric dermatology at Cardinal Glennon Children’s Hospital.

(Initial topical treatment for all these conditions is similar, but optimal treatment may differ for young children with moderate to severe disease that requires systemic treatment, she said in an interview after the meeting.)

Sparing of the diaper area that reflects skin barrier integrity is a classic feature of AD in infants and can be a useful diagnostic sign. In addition, “hypopigmentation is more characteristic of psoriasis” than AD, whereas AD tends to be hyperpigmented, which is most obvious in skin-of-color patients, Dr. Siegfried said.

Disease-specific pigment changes may be related to microbial colonization – such as Malassezia-associated hypopigmentation – or cell turnover, which is faster in psoriasis and slower in AD – with corresponding differences in pigment retention, and may be more obvious in children than adults, she said.

A less common scenario is dermatitis in infants who are not growing well. For these patients, she noted, the differential diagnosis includes metabolic or immune deficiency dermatitis as well as a variety of genodermatoses.

Generalized redness and scaling present on the first day of life is suggestive of non-atopic dermatitis. “If you’re born with red scaly skin, that’s very different than if you develop red skin in the first month or two of life,” Dr. Siegfried said.

When there is diaper area involvement with AD, contact dermatitis, impetigo, and Candida may be complicating factors. And in infants with other morbidities – especially those who are not growing well – diaper area involvement suggests a broader differential diagnosis. “I implore you, if you see children, make sure you weigh and measure them at every appointment,” she said.

Dr. Siegfried has seen infants with Netherton syndrome, and those with cystic fibrosis with zinc deficiency, for instance, presenting with “an eczematous-like picture,” diaper-area involvement, and other morbidities.

For infants with AD, she maintains a high index of suspicion for secondary infections such as molluscum, herpes simplex virus (HSV) with or without streptococci, scabies, tinea, and group A streptococci. “Secondary infections ... may be incognito,” she said. “Look for subtle signs. Even molluscum can be very subtle.”

Secondary allergic contact dermatitis is also common although it’s “technically difficult to confirm the diagnosis,” she said. Patch testing in infants is technically challenging, sensitivity is low, and monosensitization is uncommon. “So I do initial empiric topical allergen avoidance,” she said, keeping in mind ubiquitous and avoidable topical allergens such as Kathon, cocamidopropyl betaine, propylene glycol, disperse blue, and adhesives.
 

Treating AD in infancy

Irritation “is probably one of the biggest triggers” of AD in infants, and the often “pristine” diaper area compared with inflamed eczema elsewhere can demonstrate the importance of moisturization for healthy skin in atopic infants, Dr. Sidbury said.

Among treatments that “punch above their weight” for AD in infants is an ointment-based barrier applied around the mouth, chin, and chest – where the wet/dry impact of drooling is maximal – before and after meals, he said.

Another is hydrocortisone 2.5% mixed 1:1 with mupirocin for those infants who have secondary infections and “that exudative, weepy-looking appearance on the face,” he said. The topical antibiotic in the combination cream “lessens the potency of the steroid and oftentimes by synergy, makes it more effective” by simultaneously treating inflammation, he said. He cautions against products containing neomycin, which can be an allergen.

A combination antibiotic-steroid-emollient cream (the Aron Regimen) can also “sometimes punch above its weight,” Dr. Sidbury said.

Infections typically involve Staphylococcus aureus, but in up to 16% of cases Streptococcus is involved. And notably, lurking underneath the honey-colored crusting of S. aureus infections may be the grouped vesicles that characterize eczema herpeticum, Dr. Sidbury said.

“Counsel [parents] preemptively to treat cold sores immediately [in order to] decrease HSV shedding and minimize risk to their baby,” Dr. Sidbury said.

For treating AD-associated inflammation in skin not affected by secondary infections, over-the-counter 1% hydrocortisone cream is often sufficient, and “for very young babies and preemies in particular, I generally don’t use anything stronger because their skin barrier isn’t fully complete yet, so they absorb more than an older child does,” he said, referring to ages 2 months corrected as a marker for considering a stronger formulation if needed.

Many parents are “very concerned” about topical corticosteroid (TCS) use and pediatricians are also “often concerned,” Dr. Sidbury said. Addressing this concern, he tries to provide context and promote adherence by pointing out that infants have an easily visible vein at the temple area where the skin is naturally thin. If parents were to see this appearance for the first time in other areas while using topical steroids, he tells them, it may be the first sign of skin thinning, but “it’s entirely reversible at that stage.”

He also stressed the cost of not treating. It’s unknown whether “treating aggressively early on prevents any future development or manifestation of eczema, or future comorbidities, but we don’t know that it doesn’t,” Dr. Sidbury said. “And we certainly know how miserable that baby with eczema can be in the short term. So we need to use these medicines.”

Dr. Sidbury utilizes tacrolimus 0.03% ointment, a topical calcineurin inhibitor (TCI), only if he is worried about overuse of steroids, and uses a regimen that alternates the TCI (used in infants off-label because it is approved for ages 2 years and older) with TCS in periods of similar duration (for example, treatment with TCS for 1 week and TCI for 1 week, or rotations of 2 weeks each or 3 days each). “And these rotations may be dynamic depending on severity of the flare at any given time,” he said after the meeting.

Preapproval data from the pivotal trials of tacrolimus are reassuring and can be shared with parents. “Two-year-olds had 90% of BSA [body surface area] treated for 12 weeks” with no signs of systemic risks, Dr. Sidbury said at the meeting.

Crisaborole, a topical phosphodiesterase 4 (PDE4) inhibitor approved for AD down to age 3 months, does not, like tacrolimus, have a boxed warning about a possible risk for cancer, and may also be alternated with TCSs. It will cause stinging in some children, but TCSs and TCIs can also sting in some children, he said, noting that samples can be helpful to predict what will or won’t sting each infant.
 

Systemic treatment in infants

The Liberty AD PRESCHOOL phase 3 trial that supported the FDA’s approval of dupilumab down to 6 months of age, published in 2022 in The Lancet, covered ages 6 months to 5 years but included only six children under the age of 2, “leaving us with a very limited dataset in this age group,” Dr. Eichenfield said at the meeting.

Other data and analyses that have provided reassurance, such as a laboratory safety analysis published online in 2022 showing no meaningful changes in laboratory safety parameters in children as young as 6 months, and pediatric data (not including infants) presented at a RAD meeting in 2022 showing that dupilumab, an interleukin-4 receptor alpha antagonist, may have positive effects on bone mineral density.

Data from the Liberty AD PRESCHOOL open-label extension study presented at the American Academy of Dermatology meeting in 2023, meanwhile, show that “the adverse event profile is not looking much different than what we see in older children,” Dr. Eichenfield said. “There are low rates of severe adverse events and a very low rate of discontinuations.”

At Rady Children’s Hospital, where Dr. Eichenfield is chief of pediatric and adolescent dermatology, dupilumab has become a first-line systemic agent for severe infantile AD, supplanting prior traditional but little used systemic agents such as oral corticosteroids, cyclosporine, methotrexate, azathioprine, or mycophenolate, he said after the meeting.

The decision to use systemics in the first 2 years of life is “a comprehensive one,” requiring knowledge of the child’s history, disease course, and assessment of response to prior therapies, comorbidities and severity, he said.
 

Food allergy in infants with AD

Food allergy is common in children with moderate to severe AD, but true food-triggered AD, with AD being the only symptom of food allergy, is rare, said Anne Marie Singh, MD, associate professor in the division of allergy and immunology and rheumatology at the University of Wisconsin, Madison, who focuses on pediatrics.

Over the years, studies of double-blind placebo-controlled food challenge tests in children with AD have tended to conflate immediate IgE hypersensitivity (and skin symptoms like urticaria) with AD, said Dr. Singh, who directs the university’s Food Allergy Research and Education Center of Excellence. In a recently published study she led involving 374 children with AD referred to allergy and/or dermatology subspecialty clinics at the University of Wisconsin, Madison, 55% had a food allergy but only 2% had food-triggered AD “where eczema is the only symptom and removal of the food cleared up the eczema and its return brought it back,” Dr. Singh said at the meeting. Another 4% had combined IgE-mediated food allergy and food-triggered AD. Almost half of the children with food-triggered AD were under 1 year of age, and egg was the most common trigger, she noted.

Food should be implicated largely by history, Dr. Singh emphasized.

Food allergy testing in the context of AD can be done but is challenging, with the clinical relevance of skin prick testing and food-specific immunoglobulin E (sIgE) difficult to predict. Predictive values of sIgE levels are established for immediate IgE mediated food allergy, but “cut-offs” for food-triggered AD are not established, she explained, noting that “cut-offs are likely higher for our children with AD.”

Elimination diets, moreover, pose significant risks of future oral tolerance and risks of nutritional deficiencies and poor growth, Dr. Singh said. New and immediate reactions to foods that are reintroduced after an elimination diet are common, and research has shown that 20% or more of such reactions involve anaphylaxis. “If an elimination diet is undertaken, you need emergency action plans, injectable epinephrine, and nutrition counseling,” she said.

A recent systematic review and meta-analysis conditionally recommended against elimination diets for the treatment of AD, Dr. Singh noted.

Asked by Dr. Sidbury whether there “is a sweet spot where you can eliminate [foods] without going all the way,” Dr. Singh said she will sometimes do a “diagnostic elimination trial” with food elimination for 2-4 weeks only – a time period after which “I’ll feel really comfortable reintroducing the food.”

Dr. Singh urged dermatologists to “know your allergist” because “patients respond best with a consistent message.”

Dr. Singh reported ties with Incyte and Siolta Therapeutics. Dr. Eichenfield reported ties with Pfizer, Regeneron, Sanofi Genzyme, Incyte, and Pfizer.

Data from the Liberty AD PRESCHOOL open-label extension study presented at the American Academy of Dermatology meeting in 2023, meanwhile, show that “the adverse event profile is not looking much different than what we see in older children,” Dr. Eichenfield said. “There are low rates of severe adverse events and a very low rate of discontinuations.”

At Rady Children’s Hospital, where Dr. Eichenfield is chief of pediatric and adolescent dermatology, dupilumab has become a first-line systemic agent for severe infantile AD, supplanting prior traditional but little used systemic agents such as oral corticosteroids, cyclosporine, methotrexate, azathioprine, or mycophenolate, he said after the meeting.

The decision to use systemics in the first 2 years of life is “a comprehensive one,” requiring knowledge of the child’s history, disease course, and assessment of response to prior therapies, comorbidities and severity, he said.
 

Food allergy in infants with AD

Food allergy is common in children with moderate to severe AD, but true food-triggered AD, with AD being the only symptom of food allergy, is rare, said Anne Marie Singh, MD, associate professor in the division of allergy and immunology and rheumatology at the University of Wisconsin, Madison, who focuses on pediatrics.

Over the years, studies of double-blind placebo-controlled food challenge tests in children with AD have tended to conflate immediate IgE hypersensitivity (and skin symptoms like urticaria) with AD, said Dr. Singh, who directs the university’s Food Allergy Research and Education Center of Excellence. In a recently published study she led involving 374 children with AD referred to allergy and/or dermatology subspecialty clinics at the University of Wisconsin, Madison, 55% had a food allergy but only 2% had food-triggered AD “where eczema is the only symptom and removal of the food cleared up the eczema and its return brought it back,” Dr. Singh said at the meeting. Another 4% had combined IgE-mediated food allergy and food-triggered AD. Almost half of the children with food-triggered AD were under 1 year of age, and egg was the most common trigger, she noted.

Food should be implicated largely by history, Dr. Singh emphasized.

Food allergy testing in the context of AD can be done but is challenging, with the clinical relevance of skin prick testing and food-specific immunoglobulin E (sIgE) difficult to predict. Predictive values of sIgE levels are established for immediate IgE mediated food allergy, but “cut-offs” for food-triggered AD are not established, she explained, noting that “cut-offs are likely higher for our children with AD.”

Elimination diets, moreover, pose significant risks of future oral tolerance and risks of nutritional deficiencies and poor growth, Dr. Singh said. New and immediate reactions to foods that are reintroduced after an elimination diet are common, and research has shown that 20% or more of such reactions involve anaphylaxis. “If an elimination diet is undertaken, you need emergency action plans, injectable epinephrine, and nutrition counseling,” she said.

A recent systematic review and meta-analysis conditionally recommended against elimination diets for the treatment of AD, Dr. Singh noted.

Asked by Dr. Sidbury whether there “is a sweet spot where you can eliminate [foods] without going all the way,” Dr. Singh said she will sometimes do a “diagnostic elimination trial” with food elimination for 2-4 weeks only – a time period after which “I’ll feel really comfortable reintroducing the food.”

Dr. Singh urged dermatologists to “know your allergist” because “patients respond best with a consistent message.”

BALTIMORE – Less than half of the pregnant patients who met the criteria for thyroid screening were actually screened by their clinician, according to a retrospective cohort study presented at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists in Baltimore. Those who met criteria and did receive screening had higher live birth rates and lower miscarriage rates than those who met the criteria but did not undergo screening, the study found.

“These results suggest that improving thyroid screening adherence may lead to improved pregnancy outcomes,” lead author Allan Dong, MD, of Advocate Lutheran General Hospital in Des Plaines, Ill., told attendees. “However, following targeted screening guidelines can be difficult for clinicians. In practice, universal screening for diabetes and pregnancy may provide more comprehensive screening coverage and potentially lead to improved outcomes.”

Instead of universal screening for thyroid disease, ACOG and the American Thyroid Association recommend targeted screening of high-risk patients, though ATA’s criteria are substantially broader than ACOG’s. But, Dr. Dong told attendees, “guidelines are only beneficial if they are followed appropriately,” and Ob.Gyns. have limited time to screen for risk factors in the midst of other clinical priorities. So he aimed to learn whether Ob.Gyns. were following the guidelines of either organization in screening people at higher risk for thyroid disease.

Dr. Dong and his coauthor, Melisa Lott, DO, reviewed the charts of all 1,025 patients who presented at their institution for new obstetrical visits in 2020 to determine which ones had risk factors that would qualify them for screening under ATA or ACOG guidelines. ACOG’s screening criteria included having a personal or family history of thyroid disease or type 1 diabetes, or there being clinical suspicion for thyroid disease. ATA’s screening criteria included the following:

• Personal or family history of thyroid disease.
• History of head or neck radiation.
• History of a prior thyroid surgery.
• Over age 30.
• Any autoimmune disease.
• A body mass index greater than 40 kg/m².
• History of pregnancy loss, preterm delivery, or infertility.
• Recently used amiodarone lithium or iodine-based contrast.
• Lived in an area of known iodine deficiency.
• Clinical suspicion of thyroid disease.

ATA screening criteria identified four times as many patients requiring screening than did ACOG criteria, Dr. Dong noted. Of the 198 patients who met ACOG’s criteria, 43.9% were screened with thyroid function testing. Meanwhile, 826 patients – including all those who met ACOG’s criteria – met ATA’s criteria for screening, but only 13.1% of them underwent thyroid function testing.

Live birth rates were significantly higher among patients who met ATA criteria and were screened (92.6%) than among patients who met ATA criteria but were not screened (83.3%, P = .006). Similarly, the miscarriage rate was 4.6% in patients who met ATA criteria and were screened, compared to 12.4% in patients who met the criteria but did not undergo thyroid function testing (P = .009).

“A similar difference, although not statistically significant, was noted when comparing patients who were screened appropriately per ACOG criteria with those who met criteria for screening but were not screened,” Dr. Dong told attendees. “However, our study was underpowered to detect this difference due to the lower number of patients who meet criteria for screening under ACOG guidelines.”

The researchers did not find any significant difference in preterm delivery rates.

Anna Whelan, MD, of Women & Infants Hospital of Brown University, Providence, R.I., was not involved in the study but viewed the poster and pointed out that many of the patients, if seen by a primary care provider prior to pregnancy, would likely have been screened by their PCP. The rate of underscreening therefore suggests that patients “are not getting good, consistent primary care because there’s a lack of primary care physicians,” Dr. Whelan said in an interview.

In addition, she added, “maybe not all obstetricians and those providing care, such as midwives and other providers, are aware of the [ATA] guidelines on who should be screened.” She added that additional education about thyroid screening guidelines might be helpful for providers.

In a sign of the power of combination therapy for high-risk chronic lymphocytic leukemia (CLL), a small new study showed that patients were more likely to reach undetectable measurable residual disease (U-MRD) when they added venetoclax to their drug regimen after a year or more of taking ibrutinib.

Of 45 patients, 57% reached U-MRD at 12 months, and 55% reached complete remission, according to the study, published in Leukemia.

By adding venetoclax, “you can get very deep remissions in high-risk patients with ibrutinib,” lead author Philip A. Thompson, MBBS, a hematologist-oncologist with the University of Melbourne and Peter MacCallum Cancer Center, also in Melbourne, said in an interview. “This is a significant advance for really high-risk patients.”

According to Dr. Thompson, Bruton’s tyrosine kinase inhibitors like ibrutinib have revolutionized the treatment of high-risk CLL by forcing the disease into remission for several years and allowing patients to avoid stem cell transplants. “But the drug doesn’t eradicate the disease,” he said, “so eventually these patients develop progression.”

The current hope, he said, is to use a combination therapy like ibrutinib and venetoclax to send CLL into remission with lower chance of drug resistance and then allow patients to stop taking the medications.

Previous research has supported the combination of ibrutinib and venetoclax in CLL in the frontline setting, and the European Commission approved it in 2022 for that use. But “ours is the first [study] that looked at patients who’ve been on ibrutinib for a long time and added venetoclax,” Dr. Thompson said. In some cases, he said, patients in the study had been on ibrutinib for several years.

For the new study, researchers at the University of Texas MD Anderson Cancer Center in Houston – where Dr. Thompson used to work – tracked 45 patients (average age, 68.5 years; 51-80 years) with CLL or small lymphocytic lymphoma who had MRD but no clinical disease progression. They all had at least 1 high-risk feature such as a mutated TP53. They’d been on ibrutinib for a median of 32 months (12-73 months), and two were in complete remission but with MRD.

An intention-to-treat analysis found that 71% reached U-MRD when they finished taking venetoclax. “We were actually pleasantly surprised by the high rate of undetectable MRD,” Dr. Thompson said.

At a median 41-month follow-up, 11% of patients had progressed, but none had died of CLL or Richter transformation, a deadly complication of CLL. “The main side effects were neutropenia and diarrhea, which we were manageable,” Dr. Thompson said.

It’s not clear why the drug combination is especially effective, he said, but it may be because the medications are synergistic. According to the National Cancer Institute, synergy in medicine refers to “the interaction of two or more drugs when their combined effect is greater than the sum of the effects seen when each drug is given alone.”

The findings suggest that “you can get deep remissions in high-risk patients with ibrutinib and venetoclax with very with good tolerability and very low risk of on-treatment progression,” Dr. Thompson said. “We don’t yet have enough progression events to talk about retreatment data, but we do feel that retreatment with Bruton’s tyrosine kinase inhibitors – plus or minus venetoclax – will be successful in the vast majority of patients.”

The combination can be given off label in the United States, Dr. Thompson added. As for expense, adding venetoclax will double the cost of ibrutinib. The two drugs are some of the most expensive medications in the world. But patients will save money if they can stop therapy when they reach remission.

In an interview, hematologist-oncologist Kerry A. Rogers, MD, of Ohio State University, Columbus, who is not involved with the study, praised the research: “While small, this study does say quite a bit about this as a strategy to help people discontinue ibrutinib prior to resistance developing.”

She noted that Bruton’s tyrosine kinase inhibitors “are generally given as a continuous monotherapy, and venetoclax is usually given for a fixed duration in combination with an anti-CD20 antibody.”

Going forward, she said, “the fact that the study was in high-risk patients who have the most to gain from such a combination suggests that similar or better rates of undetectable minimal residual disease might be seen in non–high-risk groups. Additional follow-up should be reported as well as use of this strategy in a larger group of patients before this should be considered a standard approach.”

Solriamfetol (Sunosi), a norepinephrine-dopamine reuptake inhibitor, is probably more effective than other wakefulness-promoting medications in patients with obstructive sleep apnea (OSA) who have residual daytime sleepiness after conventional treatment, according to a systematic review and meta-analysis.

In a systematic review of 14 trials that included more than 3,000 patients, solriamfetol was associated with improvements of 3.85 points on the Epworth Sleepiness Scale (ESS) score, compared with placebo.

“We found that solriamfetol is almost twice as effective as modafinil-armodafinil – the cheaper, older option – in improving the ESS score and much more effective at improving the Maintenance of Wakefulness Test (MWT),” study author Tyler Pitre, MD, an internal medicine physician at McMaster University, Hamilton, Ont., said in an interview.

The findings were published online in Annals of Internal Medicine.
 

High-certainty evidence

The analysis included 3,085 adults with excessive daytime sleepiness (EDS) who were receiving or were eligible for conventional OSA treatment such as positive airway pressure. Participants were randomly assigned to either placebo or any EDS pharmacotherapy (armodafinil, modafinil, solriamfetol, or pitolisant). The primary outcomes of the analysis were change in ESS and MWT. Secondary outcomes were drug-related adverse events.

The trials had a median follow-up time of 4 weeks. The meta-analysis showed that solriamfetol improves ESS to a greater extent than placebo (high certainty), armodafinil-modafinil and pitolisant (moderate certainty). Compared with placebo, the mean difference in ESS scores for solriamfetol, armodafinil-modafinil, and pitolisant was –3.85, –2.25, and –2.78, respectively.

The analysis yielded high-certainty evidence that solriamfetol and armodafinil-modafinil improved MWT, compared with placebo. The former was “probably superior,” while pitolisant “may have little to no effect on MWT, compared with placebo,” write the authors. The standardized mean difference in MWT scores, compared with placebo, was 0.90 for solriamfetol and 0.41 for armodafinil-modafinil. “Solriamfetol is probably superior to armodafinil-modafinil in improving MWT (SMD, 0.49),” say the authors.

Compared with placebo, armodafinil-modafinil probably increases the risk for discontinuation due to adverse events (relative risk, 2.01), and solriamfetol may increase the risk for discontinuation (RR, 2.04), according to the authors. Pitolisant “may have little to no effect on drug discontinuations due to adverse events,” write the authors.

Although solriamfetol may have led to more discontinuations than armodafinil-modafinil, “we did not find convincing evidence of serious adverse events, albeit with very short-term follow-up,” they add.

The most common side effects for all interventions were headaches, insomnia, and anxiety. Headaches were most likely with armodafinil-modafinil (RR, 1.87), and insomnia was most likely with pitolisant (RR, 7.25).

“Although solriamfetol appears most effective, comorbid hypertension and costs may be barriers to its use,” say the researchers. “Furthermore, there are potentially effective candidate therapies such as methylphenidate, atomoxetine, or caffeine, which have not been examined in randomized clinical trials.”

Although EDS is reported in 40%-58% of patients with OSA and can persist in 6%-18% despite PAP therapy, most non-sleep specialists may not be aware of pharmacologic options, said Dr. Pitre. “I have not seen a study that looks at the prescribing habits of physicians for this condition, but I suspect that primary care physicians are not prescribing modafinil-armodafinil frequently for this and less so for solriamfetol,” he said. “I hope this paper builds awareness of this condition and also informs clinicians on the options available to patients, as well as common side effects to counsel them on before starting treatment.” 

Dr. Pitre was surprised at the magnitude of solriamfetol’s superiority to modafinil-armodafinil but cautioned that solriamfetol has been shown to increase blood pressure in higher doses. It therefore must be prescribed carefully, “especially to a population of patients who often have comorbid hypertension,” he said.

Some limitations of the analysis were that all trials were conducted in high-income countries (most commonly the United States). Moreover, 77% of participants were White, and 71% were male.
 

Beneficial adjunctive therapy

Commenting on the findings, Sogol Javaheri, MD, MPH, who was not involved in the research, said that they confirm those of prior studies and are “consistent with what my colleagues and I experience in our clinical practices.”

Dr. Javaheri is associate program director of the sleep medicine fellowship at Brigham and Women’s Hospital and assistant professor of medicine at Harvard Medical School, both in Boston.

While sleep medicine specialists are more likely than others to prescribe these medications, “any clinician may use these medications, ideally if they have ruled out other potential reversible causes of EDS,” said Dr. Javaheri. “The medications do not treat the underlying cause, which is why it’s important to use them as an adjunct to conventional therapy that actually treats the underlying sleep disorder and to rule out additional potential causes of sleepiness that are treatable.”

These potential causes might include insufficient sleep (less than 7 hours per night), untreated anemia, and incompletely treated sleep disorders, she explained. In sleep medicine, modafinil is usually the treatment of choice because of its lower cost, but it may reduce the efficacy of hormonal contraception. Solriamfetol, however, does not. “Additionally, I look forward to validation of pitolisant for treatment of EDS in OSA patients, as it is not a controlled substance and may benefit patients with a history of substance abuse or who may be at higher risk of addiction,” said Dr. Javaheri.

The study was conducted without outside funding. Dr. Pitre and Dr. Javaheri report no relevant financial relationships.

Solriamfetol (Sunosi), a norepinephrine-dopamine reuptake inhibitor, is probably more effective than other wakefulness-promoting medications in patients with obstructive sleep apnea (OSA) who have residual daytime sleepiness after conventional treatment, according to a systematic review and meta-analysis.

In a systematic review of 14 trials that included more than 3,000 patients, solriamfetol was associated with improvements of 3.85 points on the Epworth Sleepiness Scale (ESS) score, compared with placebo.

“We found that solriamfetol is almost twice as effective as modafinil-armodafinil – the cheaper, older option – in improving the ESS score and much more effective at improving the Maintenance of Wakefulness Test (MWT),” study author Tyler Pitre, MD, an internal medicine physician at McMaster University, Hamilton, Ont., said in an interview.

The findings were published online in Annals of Internal Medicine.
 

High-certainty evidence

The analysis included 3,085 adults with excessive daytime sleepiness (EDS) who were receiving or were eligible for conventional OSA treatment such as positive airway pressure. Participants were randomly assigned to either placebo or any EDS pharmacotherapy (armodafinil, modafinil, solriamfetol, or pitolisant). The primary outcomes of the analysis were change in ESS and MWT. Secondary outcomes were drug-related adverse events.

The trials had a median follow-up time of 4 weeks. The meta-analysis showed that solriamfetol improves ESS to a greater extent than placebo (high certainty), armodafinil-modafinil and pitolisant (moderate certainty). Compared with placebo, the mean difference in ESS scores for solriamfetol, armodafinil-modafinil, and pitolisant was –3.85, –2.25, and –2.78, respectively.

The analysis yielded high-certainty evidence that solriamfetol and armodafinil-modafinil improved MWT, compared with placebo. The former was “probably superior,” while pitolisant “may have little to no effect on MWT, compared with placebo,” write the authors. The standardized mean difference in MWT scores, compared with placebo, was 0.90 for solriamfetol and 0.41 for armodafinil-modafinil. “Solriamfetol is probably superior to armodafinil-modafinil in improving MWT (SMD, 0.49),” say the authors.

Compared with placebo, armodafinil-modafinil probably increases the risk for discontinuation due to adverse events (relative risk, 2.01), and solriamfetol may increase the risk for discontinuation (RR, 2.04), according to the authors.

Recreational marijuana use by teenagers isn’t as harmless as many people seem to think, even as it becomes increasingly legal in this country, authors of a new study say.

Teenagers who use cannabis recreationally are two to three times more likely to have depression and suicidal thoughts than those who don’t use it. And teens who have cannabis use disorder – which means they can’t stop using it despite health and social problems – are four times more likely to have those same thoughts and feelings.

The study was published in JAMA. It looked at information from 68,000 teens in the National Survey on Drug Use and Health.

Marijuana use was also linked to other issues including not doing well in school, skipping school, and getting in trouble with the police.

“Kids, year by year, have been moving towards a view that marijuana is safe and benign – that’s factually incorrect,” lead author of the study, Ryan Sultan, MD, an assistant professor of clinical psychiatry at Columbia University, New York, told Yahoo Life.

Dr. Sultan said he was surprised that recreational users had a much higher risk of mental health issues. “We typically think of recreational use as not being a concerning behavior.”

The study did not seek to explain the link between mental health problems and cannabis use.

“The more you use it, the more it negatively affects your thinking. That’s increasing the likelihood of depression and more suicidal thoughts,” Dr. Sultan said. “It’s feedback that spirals downward and gets to a place that really concerns us as child psychiatrists.”

Dr. Sultan said parents should talk to their children about marijuana use, depression, and anxiety.

NIDA and American Academy of Child and Adolescent Psychiatry provided funding for the study. One coauthor reported receiving grants and personal fees from several medical and sports organizations. The other authors reported no conflicts of interest.

The U.S. Food and Drug Administration has approved the first-ever topical gene therapy, which will be used to treat wounds in patients 6 months of age and older who have either recessive or dominant dystrophic epidermolysis bullosa (DEB), a rare skin disease.

Olivier Le Moal/Getty Images

The therapy, Vyjuvek (beremagene geperpavec, formerly known as B-VEC), uses a nonreplicating herpes simplex virus type 1 (HSV-1) vector to deliver the COL7A1 gene directly to skin cells, restoring the COL7 protein fibrils that stabilize skin structure.

Vyjuvek, developed by Krystal Biotech, is designed to be used repetitively to heal a single wound or on more than one wound. In the pivotal study, the gene therapy, delivered in a topical gel, was administered once a week for 6 months.

The FDA gave Vyjuvek priority review, approving the therapy just 9 months after Krystal filed its application for approval. Vyjuvek is also an orphan drug, giving it potentially 7 years of marketing exclusivity.

“Vyjuvek is the first FDA-approved gene therapy treatment for DEB, a rare and serious genetic skin disorder,” said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in the FDA’s statement  announcing the approval.

“With the FDA approval of Vyjuvek, the DEB population has reached a monumental milestone in the treatment of this horrible disorder,” said Brett Kopelan, executive director of debra of America, a national advocacy group for people with DEB, in a statement issued by Krystal Biotech. “Our hopes have now been realized for a safe and effective treatment for one of the most devastating symptoms of the disorder,” said Mr. Kopelan.

“This is a devastating disease,” said M. Peter Marinkovich, MD, primary investigator of Krystal’s pivotal GEM-3 trial and director of the Blistering Disease Clinic at Stanford Health Care, in the statement issued by Krystal. “Until now, doctors and nurses had no way to stop blisters and wounds from developing on dystrophic EB patient skin, and all we could do was to give them bandages and helplessly watch as new blisters formed,” said Dr. Marinkovich, who is also associate professor of dermatology at Stanford (Calif.) University School of Medicine.

“Because it’s safe and easy to apply directly to wounds, it doesn’t require a lot of supporting technology or specialized expertise, making Vyjuvek highly accessible even to patients who live far away from specialized centers,” he said.

Paras P. Vakharia, MD, PharmD, assistant professor of dermatology at Northwestern University, Chicago, said that Vyjuvek is an important advance for DEB. “This to me would be a treatment that I would consider for almost all patients,” Dr. Vakharia said in an interview.

Dr. Vakharia, who was not involved with trials of Vyjuvek, said he had concerns about whether patients might develop antibodies to either HSV or C7 but that the greater initial worry is if Vyjuvek will be affordable and accessible. “I envision that it will be a costly medication,” he said.

Mr. Kopelan, the patient advocate, said that his organization “will continue to work closely with Krystal to assure patients have ready access to Vyjuvek.”

Krystal did not respond before press time to a request for comment on pricing.

Dystrophic epidermolysis bullosa affects 1 to 3 people per million in the United States. It is caused by mutations in the COL7A1 gene, which encodes the alpha-1 chain of collagen type VII (C7) protein. C7 forms the anchoring fibrils that attach the epidermis to the underlying dermal connective tissue. COL71A mutations that lead to defective, decreased, or absent C7 can make the skin so fragile that it tears with the slightest touch.

DEB usually presents at birth and is divided into two major types depending on the inheritance pattern: recessive dystrophic epidermolysis bullosa and dominant dystrophic epidermolysis bullosa.

People with the dominant form typically have mild cases with blistering primarily on the hands, feet, knees, and elbows. The recessive form can be painful and debilitating, causing widespread blistering. Depending on the severity, it can lead to nonhealing wounds, fusing of fingers and toes, anemia, weak bones, and esophageal and genitourinary strictures. Squamous cell cancers are a frequent cause of death.

Vyjuvek is mixed into an inactive gel and is evenly applied to a wound once a week by a health care professional, according to the FDA.  

The agency recommends the following precautions for patients and caregivers:

• Avoid direct contact with treated wounds and dressings of treated wounds for 24 hours following application. Clean any area that is accidentally exposed.
• Wash hands and wear protective gloves when changing wound dressings.
• Disinfect the bandages used for the first dressing with a viricidal agent, such as 70% isopropyl alcohol, 6% hydrogen peroxide, or less than 0.4% ammonium chloride, and dispose of them in a separate, sealed plastic bag in household waste. Subsequent used dressings and cleaning materials should be disposed of in sealed plastic bags in household waste.

FDA approval of Vyjuvek was based on a randomized, double-blinded, placebo-controlled, 31-patient, phase 3 trial published in the New England Journal of Medicine, which showed that 71% of wounds treated with the gene therapy had complete healing at 3 months, compared with 20% of those treated with placebo (95% confidence interval, 29-73; P < .001). At 6 months, 67% of wounds treated with the gene therapy had complete healing, compared with 22% of wounds treated with placebo (95% CI, 24-68; P = .002).

Almost two-thirds of the patients had at least one adverse event. Most were mild or moderate. The most common events were pruritus, chills, and squamous cell carcinoma, reported in three patients each. SCC cases occurred at wound sites that had not been exposed to Vyjuvek or placebo. Serious adverse events, which were unrelated to the treatment, occurred in three patients and included diarrhea, anemia, and cellulitis.

Krystal will also be seeking marketing approval for Vyjuvek in the European Union, likely in 2024, said the company. In September, the European Medicines Agency’s Pediatric Committee issued a positive opinion on the gene therapy and Krystal’s plan to test B-VEC in children.

Dr. Marinkovich and Dr. Vakharia have disclosed no relevant financial relationships.

The therapy, Vyjuvek (beremagene geperpavec, formerly known as B-VEC), uses a nonreplicating herpes simplex virus type 1 (HSV-1) vector to deliver the COL7A1 gene directly to skin cells, restoring the COL7 protein fibrils that stabilize skin structure.

Vyjuvek, developed by Krystal Biotech, is designed to be used repetitively to heal a single wound or on more than one wound. In the pivotal study, the gene therapy, delivered in a topical gel, was administered once a week for 6 months.

The FDA gave Vyjuvek priority review, approving the therapy just 9 months after Krystal filed its application for approval. Vyjuvek is also an orphan drug, giving it potentially 7 years of marketing exclusivity.

“Vyjuvek is the first FDA-approved gene therapy treatment for DEB, a rare and serious genetic skin disorder,” said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in the FDA’s statement  announcing the approval.

“With the FDA approval of Vyjuvek, the DEB population has reached a monumental milestone in the treatment of this horrible disorder,” said Brett Kopelan, executive director of debra of America, a national advocacy group for people with DEB, in a statement issued by Krystal Biotech. “Our hopes have now been realized for a safe and effective treatment for one of the most devastating symptoms of the disorder,” said Mr. Kopelan.

“This is a devastating disease,” said M. Peter Marinkovich, MD, primary investigator of Krystal’s pivotal GEM-3 trial and director of the Blistering Disease Clinic at Stanford Health Care, in the statement issued by Krystal. “Until now, doctors and nurses had no way to stop blisters and wounds from developing on dystrophic EB patient skin, and all we could do was to give them bandages and helplessly watch as new blisters formed,” said Dr. Marinkovich, who is also associate professor of dermatology at Stanford (Calif.) University School of Medicine.

“Because it’s safe and easy to apply directly to wounds, it doesn’t require a lot of supporting technology or specialized expertise, making Vyjuvek highly accessible even to patients who live far away from specialized centers,” he said.

Paras P. Vakharia, MD, PharmD, assistant professor of dermatology at Northwestern University, Chicago, said that Vyjuvek is an important advance for DEB. “This to me would be a treatment that I would consider for almost all patients,” Dr. Vakharia said in an interview.

Dr. Vakharia, who was not involved with trials of Vyjuvek, said he had concerns about whether patients might develop antibodies to either HSV or C7 but that the greater initial worry is if Vyjuvek will be affordable and accessible. “I envision that it will be a costly medication,” he said.

Mr. Kopelan, the patient advocate, said that his organization “will continue to work closely with Krystal to assure patients have ready access to Vyjuvek.”

Krystal did not respond before press time to a request for comment on pricing.

Dystrophic epidermolysis bullosa affects 1 to 3 people per million in the United States. It is caused by mutations in the COL7A1 gene, which encodes the alpha-1 chain of collagen type VII (C7) protein. C7 forms the anchoring fibrils that attach the epidermis to the underlying dermal connective tissue. COL71A mutations that lead to defective, decreased, or absent C7 can make the skin so fragile that it tears with the slightest touch.

DEB usually presents at birth and is divided into two major types depending on the inheritance pattern: recessive dystrophic epidermolysis bullosa and dominant dystrophic epidermolysis bullosa.

People with the dominant form typically have mild cases with blistering primarily on the hands, feet, knees, and elbows. The recessive form can be painful and debilitating, causing widespread blistering. Depending on the severity, it can lead to nonhealing wounds, fusing of fingers and toes, anemia, weak bones, and esophageal and genitourinary strictures. Squamous cell cancers are a frequent cause of death.

Vyjuvek is mixed into an inactive gel and is evenly applied to a wound once a week by a health care professional, according to the FDA.  

The agency recommends the following precautions for patients and caregivers:

• Avoid direct contact with treated wounds and dressings of treated wounds for 24 hours following application. Clean any area that is accidentally exposed.
• Wash hands and wear protective gloves when changing wound dressings.
• Disinfect the bandages used for the first dressing with a viricidal agent, such as 70% isopropyl alcohol, 6% hydrogen peroxide, or less than 0.4% ammonium chloride, and dispose of them in a separate, sealed plastic bag in household waste. Subsequent used dressings and cleaning materials should be disposed of in sealed plastic bags in household waste.

FDA approval of Vyjuvek was based on a randomized, double-blinded, placebo-controlled, 31-patient, phase 3 trial published in the New England Journal of Medicine, which showed that 71% of wounds treated with the gene therapy had complete healing at 3 months, compared with 20% of those treated with placebo (95% confidence interval, 29-73; P < .001). At 6 months, 67% of wounds treated with the gene therapy had complete healing, compared with 22% of wounds treated with placebo (95% CI, 24-68; P = .002).

Almost two-thirds of the patients had at least one adverse event. Most were mild or moderate. The most common events were pruritus, chills, and squamous cell carcinoma, reported in three patients each. SCC cases occurred at wound sites that had not been exposed to Vyjuvek or placebo. Serious adverse events, which were unrelated to the treatment, occurred in three patients and included diarrhea, anemia, and cellulitis.

Krystal will also be seeking marketing approval for Vyjuvek in the European Union, likely in 2024, said the company. In September, the European Medicines Agency’s Pediatric Committee issued a positive opinion on the gene therapy and Krystal’s plan to test B-VEC in children.

Dr. Marinkovich and Dr. Vakharia have disclosed no relevant financial relationships.

Anticipating Food and Drug Administration approval of at least one investigational device for renal denervation (RDN) as a treatment for hypertension (HTN) refractory to medical therapies, the Society for Cardiovascular Angiography and Interventions is asking its members and the public to provide input on a draft position statement to guide use of the procedure.

The draft addresses appropriate patient selection, best practices for procedural techniques, measures for operator competence, recommendations for operator and staff training, and guidance for hospitals and centers that want to adopt RDN. SCAI is requesting feedback by June 14.

“With the anticipated FDA approval of renal denervation, there will be a need for SCAI to formulate an official position around clinical competence and training standards, best practices, and institutional and operator requirements for RDN,” Herbert D. Aronow, MD, MPH, chair of the statement writing committee, said in an interview.

RDN is an endoscopic procedure that disrupts the sympathetic nerves near the renal arteries. A number of studies, including sham-controlled, randomized trials, have shown that RDN can achieve short-term reductions in blood pressure for patients for whom HTN medications don’t work. Two devices are awaiting FDA premarket approval: the Paradise uRDN system, by ReCor Medical; and the Symplicity Spyral device, by Medtronic.

However, the trajectory of RDN has been uneven, said Dr. Aronow, president of the Society for Vascular Medicine and medical director for heart and vascular services and Benson Ford Chair in cardiology at Henry Ford Health, Detroit.

“Despite supportive early animal and human data, the first sham-controlled randomized trial of RDN was negative on its primary endpoint,” he said. “Modifications to patient inclusion/exclusion criteria, refinements in denervation technology and protocols, and selection of more appropriate study endpoints resulted in a series of positive randomized, sham-controlled trials. These second-generation trials found that RDN, when compared with sham therapy, substantially reduced ambulatory and office blood pressures.”

The draft is available for review at the SCAI website. Comments may be submitted via a link to a questionnaire.

“Through the open comment process, we are hoping to gain broad perspective from stakeholders, including clinicians, hospitals, payers, professional societies, industry and patients,” Dr. Aronow said. “By incorporating this feedback, we hope to enhance the quality of the document before we submit it for publication.”

The bulk of the SCAI draft position statement is devoted to patient selection and procedural and technical considerations. “We believe it will serve as a road map for the successful launch of RDN programs around the United States,” Dr. Aronow said.
 

Patient selection considerations

The draft statement notes that RDN for all patients with uncontrolled HTN “would not currently be practical.” The average age of patients for whom RDN showed effectiveness in the cited clinical trials was less than 60 years. The effectiveness of RDN for patients in whom arterial stiffness is a primary driver of HTN “is less certain.”

Patients who may benefit most from RDN are those with limited medical treatment options. Initially, RDN was tried on patients who had continued to experience resistant HTN despite taking three or more medications, including a diuretic, the statement noted. But even nonadherent patients may derive some potential benefit from RDN.

The statement also added that RDN isn’t a panacea; about one-third of trial patients didn’t respond to the procedure. The most reliable predictor of response may be higher levels of baseline systolic blood pressure, otherwise known as Wilder’s principle. The statement listed other potential markers of success, including higher nocturnal blood pressure and wider swings in nocturnal blood pressure.
 

Procedural and technical considerations

The statement also provided direction on a protocol for RDN procedures. The preprocedure evaluation should include noninvasive imaging to rule out disqualifying secondary causes of HTN, such as renal artery stenosis or fibromuscular dysplasia.

Patient characteristics should drive the selection of imaging modality, and availability as well as local expertise should be taken into account. The statement gave CT angiography or magnetic resonance angiography the edge over duplex ultrasound.

The statement also noted a number of anatomic considerations, citing preclinical analyses that “consistently reinforce” circumferential, perivascular RDN to ablate the renal nerves. In planning the procedure, consideration should be given to accessory renal arteries.

Additionally, operators should have training in obtaining access, and they should be familiar with different catheters and console devices as well as troubleshooting.
 

Training, competency, and institutional requirements

Interventional cardiologists who want to perform RDN should demonstrate proficiency in a number of specific skill sets germane to the procedure, from arterial vascular access and hemostasis to recognizing and treating potential renovascular complications.

For institutions that want to offer RDN, the statement offered a number of requirements. One is to designate a primary physician stakeholder who’s well versed in HTN management to oversee the long-term management of RDN patients.

The institution must have a dedicated HTN program and a multidisciplinary team to manage treated patients. Requirements for RDN referral centers range from operators experienced with FDA-approved RDN devices to an infrastructure that includes CT or MR angiography to identify appropriate candidates.

“Renal denervation has been a long time coming, and it’s a great example of how academicians, clinicians and industry leaders can partner to move the cardiovascular field forward, addressing a major public health issue for which alternative solutions are greatly needed,” Dr. Aronow said.

Dr. Aronow has served as an unpaid council member for Medtronic and as a paid moderator for ReCor.

The Food and Drug Administration has cleared Beta Bionics’s iLet ACE Pump and the iLet Dosing Decision Software for people ages 6 years and older with type 1 diabetes.
 

Working together with a previously cleared integrated continuous glucose monitor (CGM), the entire new system is called the iLet Bionic Pancreas. It differs from current automated insulin delivery (AID) systems in its increased level of automation. The adaptive algorithm is initialized using only the patient’s body weight, without other insulin dosing parameters. Rather than entering specific carbohydrate counts, users only input whether the carbohydrate amount in the meal is “small,” “medium,” or “large.” The algorithm adapts over time to users’ individual 24/7 insulin needs.

Pivotal data for the system were presented in June 2022 at the annual scientific sessions of the American Diabetes Association.

In the 16-center trial involving 440 adults and children 6 years and older with type 1 diabetes, the system reduced hemoglobin A1c by 0.5 percentage points by 13 weeks, without increased hypoglycemia. They spent an average of 2.6 hours more time in range, compared with standard of care (either currently available AIDs, stand-alone pump and CGM devices, or multiple daily injections plus CGM).

The FDA had granted the iLet a breakthrough device designation in December 2019.

Anne L. Peters, MD, a professor of medicine at the University of Southern California, Los Angeles, and director of the USC clinical diabetes program, commented on the pivotal study and the system in June 2022. She called the study “cool” because it enrolled more than 25% minority individuals “who aren’t routinely studied in these insulin device trials” and also that it included people with a range of baseline A1c levels, with more than 30% greater than 8%.

Regarding the system’s algorithm, she pointed out that it “doesn’t allow for the individual using the pump to fidget with it. They can’t override the system and they can’t put in other insulin doses. The system is just there to take care of their diabetes.”

That might represent a limitation for some with type 1 diabetes, study coprincipal investigator Roy W. Beck, MD, PhD, said in an interview during the ADA meeting. “The iLet could dramatically reduce type 1 diabetes management burden for many patients, but it might not suit everyone. For example, somebody who’s very compulsive and has an A1c of 6.5% and is used to manipulating what they do, this is probably not a good system for them because the system is kind of taking over.”

On the other hand, Dr. Peters said, “I think what’s important about this system is that it may allow for greater use of automated insulin delivery systems. It may allow primary care providers to use these systems without needing all sorts of support, and patients may be able to use these devices more simply than a device where they have to do carb counting and adjusting in ways that I think tend to be pretty complicated and require higher numeracy and literacy skills.”

The “bionic pancreas” was originally conceived as a dual-hormone system including glucagon delivery as well as insulin. Beta Bionics is continuing to work with the FDA on that front.

The U.S. Food and Drug Administration approved epcoritamab-bysp (Epkinly, AbbVie and Genmab) today for adults with relapsed/refractory diffuse large B-cell lymphoma following at least two lines of systemic therapy. This includes patients with DLBCL arising from indolent lymphoma and high-grade B-cell lymphoma.

Epcoritamab is the first subcutaneous bispecific antibody approved for the indication. The biologic simultaneously binds CD3 on cytotoxic T cells to CD20 on lymphomic B cells, inducing T-cell mediated destruction.

“Together with our partner, AbbVie, we recognize the unmet need for safe, effective, and accessible treatments for patients with B-cell malignancies and we believe that epcoritamab has the potential to become a core therapy in this patient population,” Jan van de Winkel, PhD, CEO of Genmab, said in a press release announcing the FDA’s acceptance of its biologic licensing application in November 2022.

A potential competitor, Roche’s bispecific antibody mosunetuzumab (Lunsumio), was approved in December 2022. Mosunetuzumab has the same mechanism of action as epcoritamab but is indicated for relapsed or refractory follicular lymphoma after at least two lines of systemic therapy. A phase 3 trial is currently underway exploring epcoritamab for relapsed or refractory follicular lymphoma as part of combination therapy.

The current approval was based on the open-label phase 2 EPCORE NHL-1 trial conducted by AbbVie and Genmab. The trial’s efficacy population included 148 adults with relapsed or refractory CD20+ large B-cell lymphoma who had received at least two prior lines of therapy, including anti-CD20 therapies. Almost 40% had undergone CAR-T cell therapy.

Epcoritamab was administered initially once weekly, then every 2 weeks, and then every 4 weeks until disease progression or unacceptable toxicity. The trial had no comparator arm.

At a median follow-up of 10.7 months, the overall response rate was 61% and the complete response rate was 38%. At a median follow-up of 9.8 months among responders, the median duration of response was 15.6 months.

The prescribing information comes with a boxed warning for serious or life-threatening cytokine release syndrome and life-threatening or fatal immune effector cell–associated neurotoxicity syndrome. Warnings and precautions include infections and cytopenias.

Among the 157 patients who received epcoritamab in the trial at the recommended dose, grade 1-3 cytokine release syndrome occurred in 51%, immune effector cell–associated neurotoxicity syndrome occurred in 6% (with one fatal case), and 15% experienced serious infections.

The most common grade 3 or 4 events included neutropenia (14.6%), anemia (10.2%), and thrombocytopenia (5.7%).

The FDA recommends epcoritamab be administered subcutaneously in 28-day cycles until disease progression or unacceptable toxicity.

The FDA also noted that “this indication is approved under accelerated approval based on response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.”

The U.S. Food and Drug Administration approved epcoritamab-bysp (Epkinly, AbbVie and Genmab) today for adults with relapsed/refractory diffuse large B-cell lymphoma following at least two lines of systemic therapy. This includes patients with DLBCL arising from indolent lymphoma and high-grade B-cell lymphoma.

Epcoritamab is the first subcutaneous bispecific antibody approved for the indication. The biologic simultaneously binds CD3 on cytotoxic T cells to CD20 on lymphomic B cells, inducing T-cell mediated destruction.

“Together with our partner, AbbVie, we recognize the unmet need for safe, effective, and accessible treatments for patients with B-cell malignancies and we believe that epcoritamab has the potential to become a core therapy in this patient population,” Jan van de Winkel, PhD, CEO of Genmab, said in a press release announcing the FDA’s acceptance of its biologic licensing application in November 2022.

A potential competitor, Roche’s bispecific antibody mosunetuzumab (Lunsumio), was approved in December 2022. Mosunetuzumab has the same mechanism of action as epcoritamab but is indicated for relapsed or refractory follicular lymphoma after at least two lines of systemic therapy. A phase 3 trial is currently underway exploring epcoritamab for relapsed or refractory follicular lymphoma as part of combination therapy.

The current approval was based on the open-label phase 2 EPCORE NHL-1 trial conducted by AbbVie and Genmab. The trial’s efficacy population included 148 adults with relapsed or refractory CD20+ large B-cell lymphoma who had received at least two prior lines of therapy, including anti-CD20 therapies. Almost 40% had undergone CAR-T cell therapy.

Epcoritamab was administered initially once weekly, then every 2 weeks, and then every 4 weeks until disease progression or unacceptable toxicity. The trial had no comparator arm.

At a median follow-up of 10.7 months, the overall response rate was 61% and the complete response rate was 38%. At a median follow-up of 9.8 months among responders, the median duration of response was 15.6 months.

The prescribing information comes with a boxed warning for serious or life-threatening cytokine release syndrome and life-threatening or fatal immune effector cell–associated neurotoxicity syndrome. Warnings and precautions include infections and cytopenias.

Among the 157 patients who received epcoritamab in the trial at the recommended dose, grade 1-3 cytokine release syndrome occurred in 51%, immune effector cell–associated neurotoxicity syndrome occurred in 6% (with one fatal case), and 15% experienced serious infections.

The most common grade 3 or 4 events included neutropenia (14.6%), anemia (10.2%), and thrombocytopenia (5.7%).

PHOENIX – Marijuana users have an almost four times greater risk of developing peripheral artery disease, compared with nonusers, results of a study of more than 600,000 marijuana users suggest, although there was no greater risk of death from myocardial infarction or other cardiac causes or need for revascularization.

The researchers noted, however, that the study population was young, with an average age of 37.4 years, and that the study period, from 2016 to 2019, predates the legalization of recreational marijuana in a number of states.

Nonetheless, even in this young study population, marijuana users’ risk of developing peripheral artery disease (PAD) was 3.68 times greater (P < .001) than that of nonusers. PAD at a young age could precede worse outcomes later in life, the study authors said.

“Basically, marijuana users were at increased risk of being diagnosed with peripheral artery disease, but there was no increased risk for them requiring any intervention, such as a peripheral vascular intervention, nor were they at increased risk of death from what we found,” said Hirva Vyas, DO, an internal medicine resident at Hackensack University Medical Center in New Jersey, who presented the results at the Society for Cardiovascular Angiography & Interventions annual scientific sessions.

The study used data on 623,768 marijuana users from the National Inpatient Sample, a nationwide database of inpatient visits covered by all public and commercial payers, then extracted a diagnosis for PAD from all 30 million–plus patient encounters to compare PAD rates between marijuana users and nonusers. Marijuana users were more likely to be White and to have elective rather than emergency admissions (P < .001). The researchers used diagnostic codes to identify marijuana users and PAD patients.

Recreational marijuana is legal in 22 states and the District of Columbia, according to ProCon.org. Since 2019, the last year of the study, 11 states have legalized marijuana for recreational use. “It’s a data point that we studied at one point in time, only from 2016 to 2019,” Dr. Vyas said in an interview.

“As we’ve seen over the past 4-5 years, legalization has skyrocketed and recreational use has become more and more favorable not only among younger folks but older folks,” study coauthor Harsh Jain, MD, a second-year internal medicine resident at Montefiore Medical Center in New York, said in the interview. “It would be really refreshing to see how these data change as we look at endpoints from 2019 to 2023.”

Because of the young age of the study population, Dr. Jain said, these findings may not accurately represent the true cardiovascular risks of marijuana use, especially later in life.

“One of the biggest secondary endpoints that we wanted to study was the development of chronic conditions that lead to multiple rehospitalizations, the most significant one of which would be the development of heart failure,” Dr. Jain said. “However, it was difficult to stratify because, again, many of these patients were very young and so they did not carry the diagnosis for heart failure, so we couldn’t complete that subset analysis.”

The goal is to extend the study period out to 2023, Dr. Jain said. “We know that these are very crude and rudimentary data findings that we presented so far, but we’re hoping that the final paper gives us a chance to flesh out all the details of our study and also gives us a chance to expand going forward,” he said.

The findings are in line with other research into the effects of marijuana and cardiovascular disease, said Carl “Chip” Lavie, MD, medical director for cardiac rehabilitation and prevention at the John Ochsner Heart and Vascular Institute in New Orleans who’s published a number of studies on PAD and substance use, including marijuana.

“It is known that cannabis is associated with more vasoconstriction, has sympathomimetic effects, causes endothelial dysfunction and increased platelet aggregation, and is known to increase the risk of acute myocardial infarction, especially in the hour or so after use,” he said in written comments sent to this news organization.

“It is also well known to be a cause of thromboangiitis obliterans, which is in the PAD family,” he added. “Based on these mechanisms, one would expect an increased PAD and, especially, PAD events. The 3.7-fold increased risk is supportive of this increased PAD.”

One study strength, Dr. Lavie pointed out, is that it’s one of the few studies that found an association between marijuana and PAD, which hasn’t been studied as well as other cardiovascular endpoints. “However,” he said, “the limitation is this is just an inpatient sample, and it is all based on coding – e.g., a patient could have PAD and it may not have been coded.”
