Antibody levels may wane after 7 months for people who got the Pfizer-BioNTech vaccine, according to a new study published on the bioRxiv preprint server.

In the study, which hasn’t yet been peer-reviewed or formally published in a medical journal, researchers analyzed blood samples from 46 healthy young or middle-aged adults after receiving two doses, and then 6 months after the second dose.

“Our study shows vaccination with the Pfizer-BioNTech vaccine induces high levels of neutralizing antibodies against the original vaccine strain, but these levels drop by nearly 10-fold by 7 months,” the researchers told Reuters.

In about half of the adults, neutralizing antibodies were undetectable at 6 months after the second dose, particularly against coronavirus variants such as Delta, Beta, and Mu.

Neutralizing antibodies only make up part of the body’s immune defense against the virus, Reuters noted, but they are still “critically important” in protecting against coronavirus infections.

“These findings suggest that administering a booster dose at around 6 to 7 months following the initial immunization will likely enhance protection,” the study authors wrote.

BioNTech said a new vaccine formula will likely be needed by mid-2022 to protect against future mutations of the virus, according to the Financial Times.

“This year, [a different vaccine] is completely unneeded, but by mid-next year, it could be a different situation,” Ugur Sahin, MD, cofounder and CEO of BioNTech, told the news outlet.

Current variants, namely the Delta variant, are more contagious than the original coronavirus strain but not different enough to evade current vaccines, he said. But new strains may be able to evade boosters.

“This virus will stay, and the virus will further adapt,” Dr. Sahin said. “This is a continuous evolution, and that evolution has just started.”

Serious adverse events remained rare and skin remained largely clear in adolescents treated with dupilumab for moderate to severe atopic dermatitis (AD) for up to 52 weeks in a phase 3, open-label extension trial, researchers reported.

At 1 year, 86% of 50 remaining patients with weights under 60 kg (132 lb) had achieved 75% improvement on the Eczema Area and Severity Index (EASI-75, and 77% of 51 remaining patients with weights over 60 kg reached that level of clearance. Only 5 (1.7%) of 294 patients had serious treatment-emergent adverse events (TEAEs).

The findings back up a perception that patients can stay on dupilumab for some time instead of having to switch from one biologic to another after a few years, study coauthor Eric Simpson, MD, professor of dermatology, Oregon Health & Science University, Portland, said in an interview. He added that the drug’s long-term safety profile is “very reassuring.”

The industry-funded findings of the study were released in a poster at the 2021 meeting of the World Congress of Pediatric Dermatology.

The FDA approved dupilumab (Dupixent), an interleukin-4 receptor alpha antagonist, for treating AD in adults in 2017; it is now approved for treating patients ages 6 years and older with moderate to severe atopic dermatitis whose disease is not adequately controlled with topicals.

The new study tracked patients who received at least 300 mg dupilumab subcutaneously every 4 weeks. The dose could be increased if needed to improve clinical response to once every 2 weeks (200 mg if baseline weight was <60 kg; 300 mg if ≥60 kg).

At 52 weeks, 37% of 52 patients with weights under 60 kg reached an Investigator Global Assessment (IGA) of 0/1, a level that had been fairly steady since week 16 (n = 146). Among 51 heavier patients, 49% reached an IGA of 0/1 at 52 weeks; this percentage grew steadily since baseline.

The mean percentage change in EASI was –87% in the lower-weight group (n = 50) at 52 weeks and –80.1% in the larger-weight group (n = 51). The majority of the reduction in EASI occurred in the first 4 weeks of treatment.

At 52 weeks, the mean Children’s Dermatology Life Quality Index level, which judges the effect of AD on life, was judged as “small” (low) in 71 patients. At baseline, the mean level among 189 patients was “moderate.” The levels dipped below “moderate” at week 4 and never rose above “small” after that.

“Treatment-emergent adverse events reported in ≥5% of patients were nasopharyngitis (21.1%), AD (19.4%), upper respiratory tract infection (12.4%), headache (9.4%), and oropharyngeal pain (5.7%),” the investigators wrote in the poster. They add that 6.7% of patients experienced injection-site reactions, and 8.7% of patients experienced treatment-emergent “narrow conjunctivitis,” which includes conjunctivitis, allergic conjunctivitis, bacterial conjunctivitis, viral conjunctivitis, and atopic keratoconjunctivitis.

Dr. Simpson noted that cases of conjunctivitis fell over time. It’s not clear why this adverse effect appears, he said.

He said that the findings reflect his own experience in clinic. Many of his adolescent patients took part in early dupilumab trials, he said, and dozens have been taking the drug for more than 5 years. “They just seem to get better and better,” he said.

University of Minnesota, Minneapolis, dermatologist Sheilagh Maguiness, MD, who wasn’t involved with the study, said in an interview that dupilumab remains “the safest, most effective and evidence-based therapy we had for children with moderate to severe atopic dermatitis.”

The new study’s findings are “very reassuring,” she said, and similar to those in a 2021 report that tracked long-term use of the drug in children aged 6-11.

Like Dr. Simpson, Dr. Maguiness said many pediatric patients at her clinic have stayed on the drug for more than 5 years. They still have “sustained improvement in skin disease and in their quality of life as well”

There are, however, still questions about dupilumab treatment. “For children who have responded well, when could we consider dose reduction or discontinuation? I have done this successfully just a handful of times, but I would love to see data about what percentage of pediatric patients experience rebound disease after coming off the drug and after what duration of treatment,” she said. “Another mystery that will be very interesting to unravel is the question as to whether or not early treatment with dupilumab may attenuate other atopic diseases.”

Dr. Maguiness added that “another issue specific to pediatric use of dupilumab is the recommendation surrounding vaccinations. This is an issue that should be studied in terms of antibody response and safety surrounding vaccinations, particularly as we are eagerly awaiting a pediatric FDA approval for the COVID-19 vaccine in children.”

She also urged colleagues to push back against insurers who resist paying for dupilumab. “Whether prescribing this medication on or off label, insurance companies are often requiring patients to try and fail other traditional immunosuppressive medications such as methotrexate, cyclosporine, or to pursue phototherapy,” she said. “Oftentimes, these are not practical or even safe options for children for a multitude of reasons. Don’t be shy about advocating for your patients by second- or even third-level appeals to try and gain approval for children who are in need of treatment.”

The study was funded by Sanofi Genzyme and Regeneron Pharmaceuticals. The study authors reported various disclosures. Dr. Simpson reported investigator and consultant fee relationships from various pharmaceutical companies. Dr. Maguiness was an investigator for one of the initial pediatric dupilumab trials.

Although any adverse event from an elective procedure is reasonably considered a bad outcome, some adverse events associated with cosmetic filler injections risk being catastrophic if not promptly addressed, according to an expert explaining the signs of an impending disaster at the Skin of Color Update 2021.

The most serious of the adverse events stem from vascular compromise, which is often signaled immediately by sharp pain and blanching of the skin, according to Hassan Galadari, MD, assistant professor of dermatology at the United Arab Emirates University, Dubai.

“Swift and aggressive treatment is required to avoid irreversible changes,” said Dr. Galadari, warning that blindness and vision impairment can be permanent, and that other events associated with vascular compromise include stroke and other types of embolism, as well as tissue necrosis.

To be swift, Dr. Galadari advised an immediate halt of injections and then a series of steps to abort the vascular insult. The goal is to encourage blood flow to prevent clotting and dissipate the filler.

“Massage the area like crazy. Keep on massaging. The more you massage the better. You are recruiting blood into that area so it remains viable,” Dr. Galadari said.
 

Hyaluronidase injections helpful

Warm compresses should also be applied for periods ranging from 5 minutes up to an hour, he added. In patients treated with hyaluronic acid, he also commonly introduces hyaluronidase injections of 200-500 IU diluted in lidocaine or saline. The injections are placed 2-3 cm apart and repeated every hour until signs and symptoms improve.

“Flush all of the filler out,” he said, emphasizing the urgency for reversing risk of vascular adverse events.

To sustain blood flow and avoid clots, he also recommends initiating aspirin with maintenance doses sustained over several days. Sildenafil to further improve conditions of blood perfusion can be “considered.”

The risks of vascular compromise, like other complications from filler injections, are low, but they are not zero, and the opportunity to prevent irreversible changes depends on acting quickly, according to Dr. Galadari.

“To prevent embolism, recognize the danger zones,” he advised, identifying the glabella region as the site of highest risk. The risk of vascular compromise from injections into the nasal region is lower but higher than injections of the nasolabial fold and forehead, which are associated with a relatively low risk.

Slow injections reduce risks

Some basic strategies he recommended for preventing vascular compromise included slow injections while keeping pressure low and using small volumes of filler per shot. Fractionated treatment and microdroplet techniques can be appropriate depending on the site of injection.

“Delivery of the filler by cannulas rather than by needles is preferable,” according to Dr. Galadari, who noted that a task force from the American Society for Dermatologic Surgery recently endorsed this approach as part of other recommendations to avoid complications of injectable fillers.

The Food and Drug Administration’s Manufacturer and User Facility Device Experience (MAUDE) database suggests that adverse events of any substantial severity from filler injections, not just those involving vascular compromise, occur at a rate of 1 per 3,600 cases. However, MAUDE is a passive surveillance system dependent on reports provided by clinicians and others, so this event rate might be an underrepresentation.

In the MAUDE database, complication rates are listed for each of the available filler products and show a variation in rates not just overall but also for each of the major types of complications, which include skin-specific complications such as nodules, discoloration, and inflammation, as well as neurologic adverse events, infection, and vascular compromise, Dr. Galadari reported.
 

Filler products are not interchangeable

Again, because of passive data collection, it is not clear whether the differences between products is a true representation of relative risk. Nevertheless, Dr. Galadari cautioned that these products are not necessarily interchangeable, advising clinicians to avoid products without an established safety track record.

There are a wide variety of fillers, including biostimulatory products, such as poly-L-lactic acid and calcium hydroxyapatite, and permanent fillers, such as silicone, in addition to collagen and hyaluronic acid, which function as temporary fillers, according to Dr. Galadari. He emphasized that the specific risks of each filler vary, but clinicians should always respond quickly whenever there is an adverse reaction or evidence of vascular compromise.

In flushing out filler, Cheryl M. Burgess, MD, of the Center for Dermatology and Dermatologic Surgery, Washington, who spoke at the meeting, also emphasized a prompt response. She too employs hyaluronidase injections to break down excess hyaluronic acid in the event of complications related to this filler.

Importantly, Dr. Burgess pointed out that hyaluronic acid can be considered safe for darker skin types, including Fitzpatrick skin types IV, V, and VI, but she added that speed of injection might be a particularly important variable for cosmetic procedures in skin of color.

“There is less postinflammatory hyperpigmentation with slower injection times and more with serial or multiple puncture injection technique,” she cautioned.

She further concurred with the value of cannulas over needles in most instances for facial contouring applications with filler, but she encouraged clinicians not to be overly ambitious and to move gradually toward goals.

“The desired outcome may require multiple sessions with conservative measures,” she said, indicating that conservative measures also represent a strategy to avoid adverse events.

The risk of vascular compromise from injections into the nasal region is lower but higher than injections of the nasolabial fold and forehead, which are associated with a relatively low risk.

Slow injections reduce risks

Some basic strategies he recommended for preventing vascular compromise included slow injections while keeping pressure low and using small volumes of filler per shot. Fractionated treatment and microdroplet techniques can be appropriate depending on the site of injection.

“Delivery of the filler by cannulas rather than by needles is preferable,” according to Dr. Galadari, who noted that a task force from the American Society for Dermatologic Surgery recently endorsed this approach as part of other recommendations to avoid complications of injectable fillers.

The Food and Drug Administration’s Manufacturer and User Facility Device Experience (MAUDE) database suggests that adverse events of any substantial severity from filler injections, not just those involving vascular compromise, occur at a rate of 1 per 3,600 cases. However, MAUDE is a passive surveillance system dependent on reports provided by clinicians and others, so this event rate might be an underrepresentation.

In the MAUDE database, complication rates are listed for each of the available filler products and show a variation in rates not just overall but also for each of the major types of complications, which include skin-specific complications such as nodules, discoloration, and inflammation, as well as neurologic adverse events, infection, and vascular compromise, Dr. Galadari reported.
 

Filler products are not interchangeable

Again, because of passive data collection, it is not clear whether the differences between products is a true representation of relative risk. Nevertheless, Dr. Galadari cautioned that these products are not necessarily interchangeable, advising clinicians to avoid products without an established safety track record.

There are a wide variety of fillers, including biostimulatory products, such as poly-L-lactic acid and calcium hydroxyapatite, and permanent fillers, such as silicone, in addition to collagen and hyaluronic acid, which function as temporary fillers, according to Dr. Galadari. He emphasized that the specific risks of each filler vary, but clinicians should always respond quickly whenever there is an adverse reaction or evidence of vascular compromise.

In flushing out filler, Cheryl M. Burgess, MD, of the Center for Dermatology and Dermatologic Surgery, Washington, who spoke at the meeting, also emphasized a prompt response. She too employs hyaluronidase injections to break down excess hyaluronic acid in the event of complications related to this filler.

Importantly, Dr. Burgess pointed out that hyaluronic acid can be considered safe for darker skin types, including Fitzpatrick skin types IV, V, and VI, but she added that speed of injection might be a particularly important variable for cosmetic procedures in skin of color.

“There is less postinflammatory hyperpigmentation with slower injection times and more with serial or multiple puncture injection technique,” she cautioned.

She further concurred with the value of cannulas over needles in most instances for facial contouring applications with filler, but she encouraged clinicians not to be overly ambitious and to move gradually toward goals.

“The desired outcome may require multiple sessions with conservative measures,” she said, indicating that conservative measures also represent a strategy to avoid adverse events.

Treatment with tapinarof 1%, a nonsteroidal topical cream in clinical development, was associated with durable control of plaque psoriasis in a 52-week phase 3 trial presented as a late-breaker at the virtual annual congress of the European Academy of Dermatology and Venereology.

The drug has several unique features with meaningful clinical differences from other topical psoriasis therapies, according to Linda Stein Gold, MD, director of dermatology clinical research, Henry Ford Health System, Detroit.

“The currently available nonsteroidal topical therapies are typically associated with significant irritation. We did not see that with tapinarof,” said Dr. Stein Gold. This is one of several reasons she believes this drug will be a valuable addition if it receives regulatory approval.

Tapinarof is a small-molecule aryl hydrocarbon receptor (AhR) modulating agent. AhR is widely expressed in immune cells, including macrophages, mast cells, and antigen-presenting cells. It is believed that modulation of AhR signaling by tapinarof reverses immune dysregulation that is involved in the formation of psoriatic lesions.

The newly presented PSOARING 3 data with tapinarof 1% build on the data from the 12-week PSOARING 1 and PSOARING 2 trials, which were released in August 2020 but have yet to be published.

The primary endpoint in both of the 12-week trials, each of which enrolled about 500 patients with plaque psoriasis, was a Physician Global Assessment (PGA) score of 0 (clear) or 1 (almost clear). Relative to a placebo response rate of about 6% in both trials, the proportion of patients who achieved scores of 0/1 with tapinarof 1% was 35.4% and 40.2% in the PSOARING 1 and PSOARING 2 trials, respectively (P < .0001 vs. placebo in both studies).

For the key secondary endpoint of at least 75% improvement in the Psoriasis Area and Severity Index (PASI 75), the relative advantage for tapinarof over placebo was similar. The results were highly statistically significant (P < .0001) in both of the 12-week trials.

More than 90% of the patients who participated in PSOARING 1 and PSOARING 2 and were eligible for the open-label PSOARING 3 extension trial, according to Dr. Stein Gold.

For the 79 patients with a score of 0 at the time of enrollment, tapinarof 1% was reapplied only if the PGA score reached at least 2 during the course of the study. For the 680 patients who entered with a PGA score of at least 1, once-daily applications of tapinarof 1% cream were maintained until a PGA score of 0 was achieved.

In the outcome analysis, response was defined as the proportion of patients with an initial PGA score of at least2 who achieved PGA 0. A remittive effect was defined as duration of a PGA score of 0 or 1 while off therapy after achieving a PGA score of 0. Durability of response was defined as the proportion of patients who achieved a PGA sore of 0 or 1 at least once during the study while on therapy. This last outcome provided a test of tachyphylaxis.

“Overall, 40.9% of patients achieved complete disease clearance at least once during the trial, and 58.2% who entered the study with a PGA score of 2 or higher achieved a PGA score of 0 or 1,” Dr. Stein Gold reported.

For the 79 patients who entered PSOARING 3 with a PGA score of 0 and were off treatment, the median duration of a remittive effect was 115 days. For the patients who entered the trial with a higher PGA score but who achieved a score of 0 during the study (312 patients), the mean remittive effect after discontinuing therapy was 130 days.

There was no evidence of tachyphylaxis. Rather, “there was no loss of effect despite intermittent therapy observed over the course of the trial,” Dr. Stein Gold reported.

The most common treatment-emergent adverse events in PSOARING 3, as in the previous PSOARING studies, were folliculitis, which was observed in 24.0% of patients; contact dermatitis, which occurred in 5.9% of patients; and headache, which was reported in 2%. Rates of study drug discontinuations for folliculitis and contact dermatitis were 1.2% and 1.4%, respectively. Headache did not lead to any study discontinuations.

Calling tapinarof a “first-in-class nonsteroidal,” Dr. Stein Gold suggested that this is likely to be a useful adjunctive therapy for psoriasis control. It avoids the adverse events associated with long-term topical steroid use, and its tolerability might be particularly attractive for use in sensitive areas.

“This is likely to be very useful in patients who are looking for a topical therapy for skin folds or the face, where there is a need for well-tolerated topical treatments,” Dr. Stein Gold said.

There are a lot of reasons to be positive about a new, well-tolerated topical agent for psoriasis, particularly as an alternative to topical steroids, agreed Adam Friedman, MD, director of translational research and professor and chair of the department of dermatology at George Washington University, Washington. He considers the data with tapinarof promising in general, but he also likes any new, effective topical psoriasis therapy.

“Patients and physicians are always hungry for new options, especially psoriasis patients, given many have ‘been there and done that’ with topical steroids,” Dr. Friedman said.

“Topical steroids are not irritating, but long-term use beyond recommended dosing can lead to skin thinning, lightening, tachyphylaxis, and, if really abused, HPA [hypothalamic-pituitary-adrenal] axis suppression and adrenal insufficiency,” he observed.

A topical therapy with a durable effect is particularly intriguing.

“The other issue with topical steroids is that psoriatic plaques return rather easily after stopping. The data I have seen with tapinarof show more sustainability after cessation, owing to its mechanism of action,” Dr. Friedman said. Rather than its potential for application to sensitive areas, such as the face, the durability “to me is more interesting.”

He suspects that, owing to “the incurable steroid phobia that haunts many of our patients,” an effective nonsteroidal topical option is also likely to lead to better compliance with topical treatment over time.

“A well-tolerated nonsteroidal topical drug will probably find an important place in the future management of chronic inflammatory diseases,” Marius-Anton Ionescu, MD, PhD, a dermatologist at the Hôpital Saint Louis, Paris, said in an interview. He referred to the positive effects of treatment with tapinarof in clinical trials in adults with atopic dermatitis, in addition to psoriasis.

Tapinarof 1% is also being investigated in a phase 3 study involving patients with moderate to severe atopic dermatitis. In that study, patients are as young as age 2 years. The drug is under review at the Food and Drug Administration for the plaque psoriasis indication in adults.

Dr. Stein Gold has financial relationships with Arcutis, Amgen, Bristol-Myers Squibb, Eli Lilly, Leo Pharma Ortho Dermatologic, UCB, and Dermavant Sciences, which is developing tapinarof and is provided funding for the PSOARING 3 trial. Dr. Friedman reported financial relationships with Amgen, Biogen, Encore, Galderma, GlaxoSmithKline, IntraDerm, Johnson & Johnson, Nerium, Novartis, Oculus, Onset, Pfizer, Sanova, and Valeant Pharmaceuticals. Dr. Ionescu has been a speaker or investigator (honoraria) for Celgene, Novartis, Lilly, and Uriage Cosmetics.

A one-time dose of two long-acting monoclonal antibodies reduced the risk of developing symptomatic COVID by 77% in comparison with placebo (P < .001) in a randomized, double-blind, placebo-controlled, phase 3 trial in adults, according to researchers who presented results at IDWeek 2021, an annual scientific meeting on infectious diseases.

The mix of tixagevimab and cilgavimab (AZD7442, Astra Zeneca) in a 300-mg dose is delivered in two intramuscular injections.

“This is the first long-acting combination of monoclonal antibodies that represents a potential new option to augment COVID-19 prevention,” said lead author Myron J. Levin, MD, a professor and pediatric infectious disease specialist at the University of Colorado at Denver, Aurora, who presented the findings of the PROVENT trial.

Both antibodies were taken from B cells donated by patients who had been infected with SARS-CoV-2, and they work synergistically, Dr. Levin said.

“The combination of them is better than adding results of each individually,” he said. “In vitro experiments have already shown that variants of interest and concern, including the Delta variant, are successfully neutralized by this cocktail.”

The trial was conducted in 87 sites in the United States, the United Kingdom, Spain, France, and Belgium. Participants included 5,197 unvaccinated adults who had never been infected with SARS-CoV-2 and either were at higher risk for inadequate response to COVID-19 vaccines because they were immunocompromised or were at high risk for exposure.

“Efficacy was observed through at least 3 months,” Dr. Levin said. “Preliminary pharmacokinetic modeling predicts potential protection for up to 12 months.”

Raymund Razonable, MD, an infectious disease expert with the Mayo Clinic in Rochester, Minn., who was not involved with the trial, told this news organization he was particularly interested in this combination because the developers made use of novel technology that extends the half-life of the antibodies and because of the large number of participants in the study.

Modeling that shows protection could last up to a year is novel and important, he said.

“People won’t need frequent injections,” Dr. Razonable said. With postexposure prophylaxis monoclonal cocktails, people may be given a dose a month, he noted.

Dr. Razonable said, “This is something intended to prevent COVID in people who are unvaccinated. The downside to that is we want people to get vaccinated. The best strategy so far is really vaccination.”

He said AZD7442 could potentially help fill the void for patients who are not able to respond to the COVID vaccines, including some who are immunocompromised or are undergoing chemotherapy.

Dr. Razonable said that, although the 77% reduction for developing symptomatic COVID-19 (95% confidence interval vs. placebo, 46.0-90.0; P < .001) is impressive, it is a reduction in relative risk. Still unknown is how much an individual’s absolute risk is reduced.

He also said it would be helpful to know how many people in the study population were immunocompromised, “because I think that’s where this product will be useful for prevention.”

The primary study endpoints were the first case of SARS-CoV-2 RT-PCR-positive symptomatic illness post dose and prior to day 183 (efficacy) as well as the safety of the product.

The cocktail appeared to be well tolerated. Adverse events occurred in 35% of participants administered AZD7442 and in 34% of the placebo group. Injection-site reactions occurred in 2.4% of the AZD7442 group and in 2.1% of the placebo group. There was one case of severe or critical COVID-19; two COVID-19–related deaths occurred in the placebo group.

AZD7442 is being developed with the help of funding from the U.S. government. Dr. Levin has received support from GlaxoSmithKline companies. Many of the coauthors are employed by AstraZeneca and hold stock in the company. Dr. Razonable has disclosed no relevant financial relationships.

Participants included 5,197 unvaccinated adults who had never been infected with SARS-CoV-2 and either were at higher risk for inadequate response to COVID-19 vaccines because they were immunocompromised or were at high risk for exposure.

“Efficacy was observed through at least 3 months,” Dr. Levin said. “Preliminary pharmacokinetic modeling predicts potential protection for up to 12 months.”

Raymund Razonable, MD, an infectious disease expert with the Mayo Clinic in Rochester, Minn., who was not involved with the trial, told this news organization he was particularly interested in this combination because the developers made use of novel technology that extends the half-life of the antibodies and because of the large number of participants in the study.

Modeling that shows protection could last up to a year is novel and important, he said.

“People won’t need frequent injections,” Dr. Razonable said. With postexposure prophylaxis monoclonal cocktails, people may be given a dose a month, he noted.

Dr. Razonable said, “This is something intended to prevent COVID in people who are unvaccinated. The downside to that is we want people to get vaccinated. The best strategy so far is really vaccination.”

He said AZD7442 could potentially help fill the void for patients who are not able to respond to the COVID vaccines, including some who are immunocompromised or are undergoing chemotherapy.

Dr. Razonable said that, although the 77% reduction for developing symptomatic COVID-19 (95% confidence interval vs. placebo, 46.0-90.0; P < .001) is impressive, it is a reduction in relative risk. Still unknown is how much an individual’s absolute risk is reduced.

He also said it would be helpful to know how many people in the study population were immunocompromised, “because I think that’s where this product will be useful for prevention.”

The primary study endpoints were the first case of SARS-CoV-2 RT-PCR-positive symptomatic illness post dose and prior to day 183 (efficacy) as well as the safety of the product.

The cocktail appeared to be well tolerated. Adverse events occurred in 35% of participants administered AZD7442 and in 34% of the placebo group. Injection-site reactions occurred in 2.4% of the AZD7442 group and in 2.1% of the placebo group. There was one case of severe or critical COVID-19; two COVID-19–related deaths occurred in the placebo group.

AZD7442 is being developed with the help of funding from the U.S. government. Dr. Levin has received support from GlaxoSmithKline companies. Many of the coauthors are employed by AstraZeneca and hold stock in the company. Dr. Razonable has disclosed no relevant financial relationships.

A phase 3, randomized, double-blind, controlled trial has shown that oteseconazole (Mycovia Pharmaceuticals), an oral antifungal agent, is safe and effective in treating acute and recurrent yeast infections (vulvovaginal candidiasis [VVC]) and in preventing  recurrence of acute VVC episodes.

Findings of the ultraVIOLET trial, which compared oteseconazole with the standard fluconazole, were presented at IDWeek 2021, an annual scientific meeting on infectious diseases, by lead author Mark G. Martens, MD, a professor in the department of obstetrics and gynecology at Drexel University College of Medicine in Philadelphia.

About 75% of all women will have a yeast infection in their lifetime, Dr. Martens noted. About 138 million women worldwide have recurring episodes (at least three acute episodes in the last year) of the debilitating condition.

“Recurrent vulvovaginal candidiasis typically requires treatment of the acute episode followed by long-term suppressive therapy with either weekly or biweekly fluconazole,” Dr. Martens said. However, when therapy stops, more than 50% of patients with recurrent VVC experience an infection within the next 6 months, which takes a significant toll on daily life.

Additionally, fluconazole has been linked with safety issues concerning chronic dosing, he said, citing liver toxicity, drug-drug interactions and “increased risk of miscarriage and birth defects when used during pregnancy.”

Topical treatments have been associated with messy application and burning, he noted.

For this study, researchers enrolled 219 women with a history of recurrent VVC at 51 U.S. sites. Participants were randomized either to 600 mg oteseconazole on day 1, 450 mg oteseconazole on day 2 or placebo capsules; or three sequential 150 mg doses (every 72 hours) of fluconazole together with matching placebo capsules.

In the maintenance phase, 185 women with resolved acute VVC (clinical signs and symptoms were scored below 3) on day 14 received 150 mg oteseconazole or placebo weekly for 11 weeks.

Oteseconazole was superior to fluconazole/placebo in the proportion of subjects with at least one culture-verified acute VVC episode through week 50 in the intent-to-treat population (P < .001) which included subjects who failed to clear their infection in the induction phase.

The average percentage of participants with at least one culture-verified acute VVC episode through week 50 was lower in the oteseconazole group (5.1%), compared with the fluconazole/placebo group (42.2%).

Oteseconazole was noninferior to fluconazole in the proportion of subjects with resolved acute VVC infections at day 14 – 93.2% for the oteseconazole group vs. 95.8% for the fluconazole/placebo group.

The percentages of women who had at least one treatment-emergent adverse event (TEAE) were similar – 54% in the oteseconazole group and 64% in the fluconazole/placebo group.  Most TEAEs were mild or moderate and there were no drug-related SAEs or adverse effects on liver function.

“There was no difference in the two groups in he baseline characteristics of age, race, and history of diabetes,” he said.

Oluwatosin Goje, MD, an ob.gyn. with the Cleveland Clinic told this news organization that the drug may offer another option for women who don’t respond to azoles.

“The CDC guidelines say, and I agree, that most episodes of recurrent VVC that are caused by Candida albicans will respond to topical azoles, to oral azoles, to the known drugs that are available. You just may have to use them for a prolonged period of time,” Dr. Goje said. But some patients won’t respond to azoles, the currently available drugs, and topical treatments – so new options are welcome for them, she noted.

She pointed out that the U.S. Food and Drug Administration in June approved ibrexafungerp (Brexafemme), the first oral nonazole treatment for vaginal yeast infections. It was the first approved medicine in a novel antifungal class in more than 2 decades.

Dr. Goje, who runs a large clinic with substantial numbers of women with recurrent yeast infections, said the psychosocial problems women with recurrent yeast infections face – and the time off work and money spent trying to get temporary relief from over-the-counter medications – is underestimated.

“Women have long suffered vaginitis. It can be a lot of social and economic burden. So anything in the toolbox to help women is welcome,” Dr. Goje said.

The study was sponsored by Mycovia Pharmaceuticals. Dr. Martens reports no relevant financial relationships. Several coauthors are either employees of Mycovia or receive support from the company. Dr. Goje has disclosed no relevant financial relationships.

Prurigo pigmentosa, an uncommon inflammatory skin condition also known as Nagashima disease, is growing in frequency, possibly as a result of increased interest in the ketogenic diet, according to a dermatologist, who reviewed skin conditions common to patients of Asian descent at the Skin of Color Update 2021.

“Ketogenic diets are gaining popularity globally for weight loss. After 2-4 weeks [on a strict ketogenic diet], some patients start to notice very pruritic papules on their trunk, the so-called keto rash,” reported Hye Jin Chung, MD, director of the Asian Skin Clinic, Beth Israel Deaconess Medical Center, Boston. “Keto rash is actually prurigo pigmentosa.”

The exact pathogenesis of prurigo pigmentosa, a highly pruritic macular and papular rash with gross reticular pigmentation, is unclear, but Dr. Chung reported that the strong link with ketosis might explain why more cases are now being encountered outside of east Asia. Ketosis or conditions associated with a high risk for ketosis, such as anorexia nervosa, diabetes mellitus, or recent bariatric surgery, have been linked to prurigo pigmentosa in all skin types and ethnicities.

“I tell my residents that this is a disease you will never forget after your first case,” she said.

The differential diagnosis includes contact dermatitis and other inflammatory disorders, but Dr. Chung said that the reticular pattern of the lesions is a relatively unique feature. Confluent and reticulated papillomatosis (CARP) shares a pattern of reticulated lesions, but Dr. Chung said it lacks the inflammatory erythematous papules and the severe pruritus common to prurigo pigmentosa.

Histologically, the pattern evolves. It begins as a perivascular infiltration dominated by neutrophils and eosinophils with hyperkeratosis, acanthosis, and spongiosis. Over time, Dr. Chung said that the histologic picture shows an increasing degree of dyskeratosis as keratinocytes die.

Prurigo pigmentosa was first described 50 years ago by Masaji Nagashima, MD, who published a report on eight patients in Japan with a pruriginous truncal dermatosis featuring symmetrical pigmentation. Most subsequent reports were also from Japan or other east Asian countries, but it has since spread.

This global spread was captured in a recently published review of 115 published studies and case reports from 24 countries. In this review, the proportion of studies from Europe (36.5%) approached that of those from east Asia (38.2%), even if 76% of the patients for whom race was reported were of Asian ethnicity.

Of the 369 patients evaluated in these studies and case reports, 72.1% were female. The mean age was 25.6 years. In the studies originating outside of Asia, prurigo pigmentosa was reported in a spectrum of skin types and ethnicities, including Whites, Blacks, and Hispanics. The lowest reported incidence has been in the latter two groups, but the authors of the review speculated that this condition is likely being underdiagnosed in non-Asian individuals.

Dr. Chung agreed, and she cautioned that the consequences typically result in a significant delay for achieving disease control. In recounting a recent case of prurigo pigmentosa at her center, she said that the 59-year-old Asian patient had been initiated on topical steroids and oral antihistamines by her primary care physician before she was referred. This is a common and reasonable strategy for a highly pruritic rash potentially caused by contact dermatitis, but it is ineffective for this disorder.

“Prurigo pigmentosa requires anti-inflammatory agents,” she explained. She said that doxycycline and minocycline are the treatments of choice, but noted that there are also reports of efficacy with dapsone, macrolide antibiotics, and isotretinoin.

In her most recent case, she initiated the patient on 100 mg of doxycycline twice daily. There was significant improvement within 2 weeks, and the rash resolved within a month with no relapse in follow-up that now exceeds 12 months, Dr. Chung said.

According to Dr. Chung, Asian-Americans are the most rapidly growing ethnic group in the United States, making it increasingly important to be familiar with conditions common or unique to Asian skin, but prurigo pigmentosa is no longer confined to those of Asian descent. She encouraged clinicians to recognize this disorder to reduce the common delays to effective treatment.

The senior author of the recently published review of studies, Jensen Yeung, MD, of the department of dermatology, University of Toronto, agreed. He, too, believes that dermatologists need to increase their awareness of the signs and symptoms of prurigo pigmentosa – and not just in Asian patients or patients of Asian descent.

“This diagnosis is often missed,” he contended in an interview. “This condition has become more common in the past 5 years in my clinical experience.” He added that the increasing incidence might not just be related to better diagnostic accuracy, although the most significant of other possible explanations “is not yet well understood.”

Dr. Chung reports that she has no relevant financial relationships to disclose. Dr. Yeung reports financial relationships with more than 25 pharmaceutical companies, some of which produce treatments employed in the control of prurigo pigmentosa.

Racial and ethnic disparities persist in the use of Mohs surgery to treat dermatofibrosarcoma protuberans, according to the results of a retrospective cohort study of more than 2,000 patients.

Current guidelines recommend Mohs micrographic surgery (MMS) as a first-line treatment for dermatofibrosarcoma protuberans, but the procedure may be inaccessible for certain populations and in some geographic areas, wrote Kevin J. Moore, MD, and Michael S. Chang, BA, of the department of dermatology, Brigham and Women’s Hospital, Boston, and colleagues. Wide local excision (WLE) is a less effective option; recurrence rates associated with this treatment are approximately 30% because of incomplete margin assessment, compared with about 3% with MMS, they noted.

In the study, published as a letter in the Journal of the American Academy of Dermatology, the investigators identified 2,370 cases of dermatofibrosarcoma protuberans using data from the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) Registry from 2000 to 2018. The mean age of the patients was 44 years; 55% were women. A total of 539 patients underwent MMS and 1,831 underwent WLE.

Overall, patients in the WLE group were more likely to be younger, male, Black, and single, the researchers noted. Those who had WLE, they added, were “more commonly deceased at study end date, recipients of adjuvant chemotherapy or radiation, and had truncal tumor locations.”

In a multivariate analysis, patients who were non-Hispanic, White, or other races (including American Indian, Alaskan Native, and Pacific Islander), were significantly more likely to undergo MMS compared with Black and Hispanic patients (adjusted odd ratio [aOR], 1.46, 1.66, and 2.42, respectively). Women were also significantly more likely than were men to undergo MMS (aOR, 1.24). Individuals living in the Western part of the United States were significantly more likely to undergo MMS.

The study findings were limited by several factors including the inability to control for insurance status, lack of data on re-excision, and the use of aggregate case data, the researchers noted. However, the results highlight the disparities in use of MMS for dermatofibrosarcoma protuberans, they said.

“Because MMS is associated with significantly improved outcomes, identifying at-risk patient populations and barriers to accessing MMS is essential,” the researchers noted. The results suggest that disparities persist in accessing MMS for many patients, notably Black and Hispanic males, they said. “Further work is necessary to identify mechanisms for increasing access to MMS,” they concluded.

Current guidelines recommend Mohs micrographic surgery (MMS) as a first-line treatment for dermatofibrosarcoma protuberans, but the procedure may be inaccessible for certain populations and in some geographic areas, wrote Kevin J. Moore, MD, and Michael S. Chang, BA, of the department of dermatology, Brigham and Women’s Hospital, Boston, and colleagues. Wide local excision (WLE) is a less effective option; recurrence rates associated with this treatment are approximately 30% because of incomplete margin assessment, compared with about 3% with MMS, they noted.

In the study, published as a letter in the Journal of the American Academy of Dermatology, the investigators identified 2,370 cases of dermatofibrosarcoma protuberans using data from the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) Registry from 2000 to 2018. The mean age of the patients was 44 years; 55% were women. A total of 539 patients underwent MMS and 1,831 underwent WLE.

Overall, patients in the WLE group were more likely to be younger, male, Black, and single, the researchers noted. Those who had WLE, they added, were “more commonly deceased at study end date, recipients of adjuvant chemotherapy or radiation, and had truncal tumor locations.”

In a multivariate analysis, patients who were non-Hispanic, White, or other races (including American Indian, Alaskan Native, and Pacific Islander), were significantly more likely to undergo MMS compared with Black and Hispanic patients (adjusted odd ratio [aOR], 1.46, 1.66, and 2.42, respectively). Women were also significantly more likely than were men to undergo MMS (aOR, 1.24). Individuals living in the Western part of the United States were significantly more likely to undergo MMS.

The study findings were limited by several factors including the inability to control for insurance status, lack of data on re-excision, and the use of aggregate case data, the researchers noted. However, the results highlight the disparities in use of MMS for dermatofibrosarcoma protuberans, they said.

“Because MMS is associated with significantly improved outcomes, identifying at-risk patient populations and barriers to accessing MMS is essential,” the researchers noted. The results suggest that disparities persist in accessing MMS for many patients, notably Black and Hispanic males, they said. “Further work is necessary to identify mechanisms for increasing access to MMS,” they concluded.

The proportion of patients who obtained an opioid prescription for hydrocodone after Mohs micrographic surgery fell by 21.7% between 2011 and 2020, while the use of tramadol increased by 26.3% between 2009 and 2020, according to a cross-sectional analysis of national insurance claims data.

The findings suggest that dermatologic surgeons generally understood opioid prescription risks and public health warnings about the opioid epidemic, corresponding study author Surya A. Veerabagu said in an interview.

“The frequency of opioid prescriptions after Mohs surgery went up a little bit from 2009 to 2011, but then it subsequently decreased,” said Ms. Veerabagu, a 4th-year student at Tulane University, New Orleans. “It very much correlates with the overarching opioid trends of the time. From 2010 to 2015, research questioning the safety of opioids increased and in 2012, national prescriptions claims for opioids began to decrease. More media outlets voiced concerns over the growing opioid epidemic, as well.”

As she and her associates noted in their study, published online Sept. 22 in JAMA Dermatology, sales of opioids skyrocketed, increasing by 400% from 1999 to 2011, while prescription opioid–related deaths exceeded deaths caused by heroin and cocaine combined.

“In 2016, the U.S. Department of Health and Human Services declared the opioid epidemic a public health emergency, and the Centers for Disease Control and Prevention released guidelines to curtail unnecessary opioid prescriptions,” they wrote. “Unfortunately, overdose deaths involving prescription opioids continued to increase even after these measures.”

The researchers drew from Optum Clinformatics Data Mart (Optum CDM), a nationally representative insurance claims database, and limited the analysis to 358,012 adults who underwent Mohs surgery and obtained an opioid prescription within 2 days of surgery in the United States from Jan. 1, 2009, to June 1, 2020. They found that 34.6% of patients underwent Mohs surgery with opioid claims in 2009. This rose to a peak of 39.6% in 2011, then decreased annually to a rate of 11.7% in 2020.

The four opioids obtained most during the study period were hydrocodone (55%), codeine (16.3%), oxycodone (12%), and tramadol (11.6%). However, over time, the proportion of patients who obtained hydrocodone fell 21.7% from a peak of 67.1% in 2011 to 45.4% in 2020, while the proportion of patients who obtained tramadol – generally recognized as a safer option – increased 26.3% from a low of 1.6% in 2009 to 27.9% in 2020.

“The switch from very addictive opioids like hydrocodone and oxycodone to weaker opioids like tramadol was fascinating to see,” said Ms. Veerabagu, who conducted the study during her research fellowship in the department of dermatology at the University of Pennsylvania, Philadelphia. “I remember at first thinking I had coded the data wrong. I reviewed the results with the team to ensure it was correct. We noticed that propoxyphene prescriptions suddenly dropped to 0% in 2011.” She found that the FDA warning in 2010 and recall regarding the use of propoxyphene because of cardiotoxicity correlated with her data, which, “in addition to the thorough review, convinced me that my coding was correct.” Prior to 2011, propoxyphene constituted 28% of prescriptions in 2009 and 24% of prescriptions in 2010.

In an interview, Maryam M. Asgari, MD, professor of dermatology at Harvard Medical School, Boston, said that the findings support recent opioid prescription recommendations following Mohs and other dermatologic procedures from professional societies including those from the American College of Mohs Surgery.

“More awareness has been raised in the past decade regarding the opioid epidemic and the rise of opioid abuse and deaths,” she said. “There has been increased scrutiny on procedures and prescribing of opioids post procedures.”

State-led efforts to lower the number of opioid prescriptions also play a role. For example, in 2016, Massachusetts launched the Massachusetts Prescription Awareness Tool (MassPAT), which imposes a 7-day limit on first-time prescriptions of opioids to patients and mandates that all prescribers check the prescription drug monitoring program before prescribing schedule II or III substances.

“The MassPAT system also gives you quarterly data on how your opioid prescriptions compare with those of your peers within your specialty and subspecialty,” Dr. Asgari said. “If you’re an outlier, I think that quickly leads you to change your prescribing patterns.”

Dr. Asgari noted that most opioids prescribed in the study by Ms. Veerabagu and colleagues were for cancers that arose on the head and neck. “There is still a perception among providers that cancers that arise in those anatomic sites can potentially cause more discomfort for the patient,” she said. “So, knowing more about the degree of pain among the head and neck cases would be an area of knowledge that would help provider behavior down the line.”

Ms. Veerabagu acknowledged certain limitations of the study, including the fact that unfilled prescriptions could not be accounted for, nor could opioids not taken or those obtained without a prescription. “We cannot survey patients in insurance claims database studies, so we have no way of knowing if everyone’s pain was adequately controlled from 2009 to 2020,” she said.

“The main takeaway message is to make sure doctors and patients share an open dialogue,” she added. “Informing patients of the major pros and cons of the appropriate postoperative pain management options available, including opioids’ addiction potential, is crucial. We hope our study adds to the larger continuing conversation of opioid usage within dermatology.”

Topical and oral Janus Kinase (JAK)-inhibitors are important new additions to the therapeutic armamentarium of atopic dermatitis (AD). I recently addressed some important treatment considerations regarding the JAK-inhibitors. In just two short months, there have already been a number of important new publications on JAK-inhibitors in AD that provide crucial data to guide treatment decisions.

Topical ruxolitinib 1.5% cream (a JAK1/2 inhibitor) was just approved by United States Food and Drug Administration for the treatment of mild-moderate AD. Clinicians always want to know about the comparative effectiveness of new agents compared to already approved agents. A previous phase 2B randomized controlled trial (RCT) compared multiple doses of ruxolitinib cream with a vehicle control and triamcinolone 0.1% cream active comparator¹. Topical ruxolitinib 1.5% cream was significantly more effective than vehicle and numerically more effective than triamcinolone 0.1% cream.

Zhang et al. recently conducted a network meta-analysis of 10 RCT for topical JAK and phosphodiesterase E4 (PDE4)-inhibitors, mostly with mild-to-moderate AD. All included JAK inhibitors showed higher Investigators Global Assessment (IGA) response vs. vehicle, with ruxolitinib 1.5% once daily showing similar efficacy as tofacitinib 2% and delgocitinib 3% twice daily. Whereas, topical tacrolimus 0.1% and hydrocortisone butyrate 0.1% twice a day were not more effective than vehicle at achieving IGA response. These results suggest that topical ruxolitinib and other JAK-inhibitors are more effective at clearing AD lesions than currently used topical therapies.

There has been a recent flurry of publications regarding the efficacy and safety of abrocitinib (an oral, once daily, JAK1 inhibitor) in moderate-severe atopic dermatitis.

• Eichenfield et al. published the results of the JADE TEEN study ², a phase 3 RCT of abrocitinib in adolescents. Abrocitinib 200 mg and 100 mg resulted in significant improvements of IGA, Eczema Area and Severity Index, and itch scores, etc. over a 12-week treatment period compared to placebo. These results support the efficacy of abrocitinib in adolescents with moderate-severe AD.
• Simpson et al. published the results from an integrated safety analysis of pooled data from 5 short-term and 1 long-term extension study of abrocitinib therapy ³. Abrocitinib 200 mg and 100 mg doses were well-tolerated during 12-week placebo controlled trials, with nausea, headache, and acne being the most common adverse-events. The incidence of different adverse-events did not consistently increase over time. However, there were some rare events reported for venous thromboembolism and deaths. These results indicate an overall good safety profile for abrocitinib, but proper patient and dose selection should be carefully considered.
• Additionally, strategies should be employed to potentially minimize risk of adverse-events. One such approach is flexible dosing in order to maintain long-term disease control using the lowest amount of medicine needed. Blauvelt et al. published findings from the JADE REGIMEN study ⁴. Patients who responded to 12 weeks of abrocitinib 200 mg open-label monotherapy were randomly assigned to abrocitinib 200 mg, abrocitinib 100 mg, or placebo maintenance therapy for 40-weeks. Flares occurred least commonly in patients maintained on abrocitinib 200 mg (18.9%), followed by abrocitinib 100 mg (42.6%), and most commonly for placebo (80.9%). These results indicate that a large subset of patients who achieve clinical response with abrocitinib 200 mg could be maintained on a lower dose of 100 mg and in some cases may even be able to have a drug holiday without flaring. While similar studies were not performed for other oral JAK-inhibitors, it may be that lower maintenance dosing may also be feasible and effective for other oral JAK-inhibitors. Future research is needed to identify patient subsets who will most likely maintain clinical response with lower maintenance dosing of oral JAK-inhibitors.

Topical and oral Janus Kinase (JAK)-inhibitors are important new additions to the therapeutic armamentarium of atopic dermatitis (AD). I recently addressed some important treatment considerations regarding the JAK-inhibitors. In just two short months, there have already been a number of important new publications on JAK-inhibitors in AD that provide crucial data to guide treatment decisions.

Topical ruxolitinib 1.5% cream (a JAK1/2 inhibitor) was just approved by United States Food and Drug Administration for the treatment of mild-moderate AD. Clinicians always want to know about the comparative effectiveness of new agents compared to already approved agents. A previous phase 2B randomized controlled trial (RCT) compared multiple doses of ruxolitinib cream with a vehicle control and triamcinolone 0.1% cream active comparator¹. Topical ruxolitinib 1.5% cream was significantly more effective than vehicle and numerically more effective than triamcinolone 0.1% cream.

Zhang et al. recently conducted a network meta-analysis of 10 RCT for topical JAK and phosphodiesterase E4 (PDE4)-inhibitors, mostly with mild-to-moderate AD. All included JAK inhibitors showed higher Investigators Global Assessment (IGA) response vs. vehicle, with ruxolitinib 1.5% once daily showing similar efficacy as tofacitinib 2% and delgocitinib 3% twice daily. Whereas, topical tacrolimus 0.1% and hydrocortisone butyrate 0.1% twice a day were not more effective than vehicle at achieving IGA response. These results suggest that topical ruxolitinib and other JAK-inhibitors are more effective at clearing AD lesions than currently used topical therapies.

There has been a recent flurry of publications regarding the efficacy and safety of abrocitinib (an oral, once daily, JAK1 inhibitor) in moderate-severe atopic dermatitis.

• Eichenfield et al. published the results of the JADE TEEN study ², a phase 3 RCT of abrocitinib in adolescents. Abrocitinib 200 mg and 100 mg resulted in significant improvements of IGA, Eczema Area and Severity Index, and itch scores, etc. over a 12-week treatment period compared to placebo. These results support the efficacy of abrocitinib in adolescents with moderate-severe AD.
• Simpson et al. published the results from an integrated safety analysis of pooled data from 5 short-term and 1 long-term extension study of abrocitinib therapy ³. Abrocitinib 200 mg and 100 mg doses were well-tolerated during 12-week placebo controlled trials, with nausea, headache, and acne being the most common adverse-events. The incidence of different adverse-events did not consistently increase over time. However, there were some rare events reported for venous thromboembolism and deaths. These results indicate an overall good safety profile for abrocitinib, but proper patient and dose selection should be carefully considered.
• Additionally, strategies should be employed to potentially minimize risk of adverse-events. One such approach is flexible dosing in order to maintain long-term disease control using the lowest amount of medicine needed. Blauvelt et al. published findings from the JADE REGIMEN study ⁴. Patients who responded to 12 weeks of abrocitinib 200 mg open-label monotherapy were randomly assigned to abrocitinib 200 mg, abrocitinib 100 mg, or placebo maintenance therapy for 40-weeks. Flares occurred least commonly in patients maintained on abrocitinib 200 mg (18.9%), followed by abrocitinib 100 mg (42.6%), and most commonly for placebo (80.9%). These results indicate that a large subset of patients who achieve clinical response with abrocitinib 200 mg could be maintained on a lower dose of 100 mg and in some cases may even be able to have a drug holiday without flaring. While similar studies were not performed for other oral JAK-inhibitors, it may be that lower maintenance dosing may also be feasible and effective for other oral JAK-inhibitors. Future research is needed to identify patient subsets who will most likely maintain clinical response with lower maintenance dosing of oral JAK-inhibitors.
