Key clinical point: The overall improvement in skin clearance and itch reduction suggested a preference for 30 mg upadacitinib over dupilumab and that for 15 mg or 30 mg upadacitinib over placebo in patients with moderate-to-severe atopic dermatitis (AD).

Major finding: At week 24, the aggregate response benefit for skin clearance and itch, respectively, was 32.5% and 25.8% higher with 30 mg upadacitinib vs dupilumab. The benefit favored upadacitinib over dupilumab as early as week 4. Moreover, 15 and 30 mg upadacitinib showed similar benefits over placebo.

Study details: This post hoc analysis of the data from phase 3 studies (Heads Up, Measure Up 1, and Measure Up 2) included 2356 patients with moderate-to-severe AD who received upadacitinib, dupilumab, or placebo.

Disclosures: This study was sponsored by AbbVie. Five authors declared being employees of or owning stock or stock options in AbbVie. Several authors declared being consultants, speakers, or advisors of or having other ties with various sources, including AbbVie.

Evidence-based guidelines for managing atopic dermatitis (AD) issued by The American Academy of Allergy, Asthma and Immunology/American College of Allergy, Asthma and Immunology Joint Task Force on Practice Parameters (JTFPP) incorporate a decade of new treatments and new methodological standards for making recommendations. The new guidelines update 2012 recommendations.

The JTFPP AD guidelines represent “an evolution” in trustworthy allergy guidelines and provide systematic reviews of the evidence with multidisciplinary panelist engagement, adherence to a rigorous guideline development process, the involvement of the patient and caregiver voice from start to finish, clear translation of evidence to clinically actionable and contextual recommendations, and novel approaches to facilitate knowledge translation, task force cochair Derek K. Chu, MD, PhD, said in an interview. Dr. Chu, director of the Evidence in Allergy research group at McMaster University, Hamilton, Ontario, Canada, cochaired the task force with Lynda Schneider, MD, section chief of the allergy and asthma program at Boston Children’s Hospital.

The new guidelines were published online on December 17, 2023, in Annals of Allergy, Asthma, & Immunology. They include 25 recommendations and address optimal use of topical treatments, such as topical corticosteroids, topical calcineurin inhibitors, topical JAK inhibitors, topical crisaborole, and topical antimicrobials; dilute bleach baths; dietary elimination; allergen immunotherapy by subcutaneous (SCIT) and sublingual (SLIT) routes; and systemic treatments with dupilumab and tralokinumab, cyclosporine, azathioprine, methotrexate, mycophenolate, oral JAK inhibitors, systemic corticosteroids; and phototherapy.

“There’s something in here for all clinicians — from primary care to AD experts— and patients may benefit as well, so the key individual recommendations will vary,” Dr. Chu told this news organization.

“Throughout the guideline, we emphasize shared decision-making, key factors to consider for each recommendation, and the specific evidence behind each recommendation,” he said. “There is a major focus on addressing equity, diversity, inclusiveness; and addressing health disparities, and key gaps to address in future research.”

Among the changes to the 2012 JTFPP guidelines, the 2023 update suggests using dilute bleach baths for patients with AD with moderate to severe disease as an additive therapy and suggests using allergen immunotherapy (AIT) for moderate to severe AD.

In other changes, the 2023 update suggests against using elimination diets for AD; recommends against very low dose baricitinib (1 mg); suggests against azathioprine, methotrexate, and mycophenolate mofetil; and suggests against adding topical JAK inhibitors, such as ruxolitinib, for patients with mild to moderate AD refractory to moisturization alone.

The 38-page guidelines include an infographic that summarizes comparative effects of systemic treatments on patient-important outcomes for AD that are important to patients, and includes other key summary tables that can be used at the point of care.

In addition to addressing evidence underlying each recommendation, the guideline’s eAppendix contains 1- to 2-page handouts that address practical issues for each treatment and can be used to facilitate shared decision making.

Dr. Chu said that the updated guidelines “provide important changes to almost all aspects of AD care — my own and my colleagues’ — and I strongly recommend all clinicians treating AD to read the full guidelines and use them in clinical practice. We’re grateful to all our contributors, especially our patient and caregiver partners, for helping make these guidelines. We will continue to periodically update the guidelines as part of maintaining them as living guidelines.”

The guidelines incorporate the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach for assessing the certainty of the evidence.

The work was funded by the AAAAI/ACAAI JTFPP. Dr. Chu disclosed that he has received a faculty development award from the AAAAI Foundation and research grants to McMaster from the Canadian Institutes of Health Research, the Ontario Ministry of Health, and the Ontario Medical Association.

“There’s something in here for all clinicians — from primary care to AD experts— and patients may benefit as well, so the key individual recommendations will vary,” Dr. Chu told this news organization.

“Throughout the guideline, we emphasize shared decision-making, key factors to consider for each recommendation, and the specific evidence behind each recommendation,” he said. “There is a major focus on addressing equity, diversity, inclusiveness; and addressing health disparities, and key gaps to address in future research.”

Among the changes to the 2012 JTFPP guidelines, the 2023 update suggests using dilute bleach baths for patients with AD with moderate to severe disease as an additive therapy and suggests using allergen immunotherapy (AIT) for moderate to severe AD.

In other changes, the 2023 update suggests against using elimination diets for AD; recommends against very low dose baricitinib (1 mg); suggests against azathioprine, methotrexate, and mycophenolate mofetil; and suggests against adding topical JAK inhibitors, such as ruxolitinib, for patients with mild to moderate AD refractory to moisturization alone.

The 38-page guidelines include an infographic that summarizes comparative effects of systemic treatments on patient-important outcomes for AD that are important to patients, and includes other key summary tables that can be used at the point of care.

In addition to addressing evidence underlying each recommendation, the guideline’s eAppendix contains 1- to 2-page handouts that address practical issues for each treatment and can be used to facilitate shared decision making.

Dr. Chu said that the updated guidelines “provide important changes to almost all aspects of AD care — my own and my colleagues’ — and I strongly recommend all clinicians treating AD to read the full guidelines and use them in clinical practice. We’re grateful to all our contributors, especially our patient and caregiver partners, for helping make these guidelines. We will continue to periodically update the guidelines as part of maintaining them as living guidelines.”

The guidelines incorporate the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach for assessing the certainty of the evidence.

The work was funded by the AAAAI/ACAAI JTFPP. Dr. Chu disclosed that he has received a faculty development award from the AAAAI Foundation and research grants to McMaster from the Canadian Institutes of Health Research, the Ontario Ministry of Health, and the Ontario Medical Association.

In the opinion of David Rosmarin, MD, the approval of dupilumab in 2017 for the treatment of moderate to severe, resistant atopic dermatitis (AD) marked an inflection point in dermatology.

“Dupilumab has revolutionized AD, and the [interleukin] IL-4 receptor target isn’t going away,” Dr. Rosmarin, who chairs the department of dermatology at Indiana University, said at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. “It’s truly an exciting time because we have a lot of different treatments in the pipeline that target IL-4 and other receptors.”

In a review of AD biologic therapies in development, he highlighted the following:

CM310 (Stapokibart): This IL-4 receptor alpha monoclonal antibody, which is being developed by Keymed Biosciences, inhibits IL-4 and IL-13 signaling. In a phase 3 randomized study of patients with moderate to severe AD, presented as an abstract at the 2023 European Academy of Dermatology and Venereology (EADV) meeting, it showed results similar to those of dupilumab. Specifically, at week 16, Eczema Area and Severity Index (EASI)-75 scores were achieved in 66.9% of patients in the CM310 group and 25.8% of patients in the placebo group, while the proportion of patients achieving an Investigator Global Assessment (IGA) score of 0 or 1 (clear or almost clear) with a reduction of greater than or equal to 2 points from baseline was 44.2% in the CM310 group, compared with 16.1% in the placebo group (P < .0001 for both associations). According to Dr. Rosmarin, other novel anti-IL-4 receptor antibodies for AD include AK120, which is being developed by Akeso Biopharma, and CBP-201 (rademikibart), which is being developed by Connect Biopharma.

Eblasakimab. Under development by ASLAN Pharmaceuticals, this biologic is a potential first-in-class, monoclonal antibody that binds to IL-13Ralpha1 with high affinity and blocks the signaling of IL-4 and IL-13 through the type-2 receptor. In the TREK-AD monotherapy phase 2b trial in patients with moderate to severe AD, presented as an abstract at the 2023 EADV meeting, the primary endpoint of EASI percent change from baseline to week 16, was met for eblasakimab doses 600 mg Q4W, 300mg Q2W, and 400mg Q2W vs. placebo (73.0% [P = .001], 69.8% [P = .005], and 65.8% [P = .029] vs. 51.1%), respectively.

Nemolizumab. Under development by Galderma, nemolizumab is a first-in-class IL-31 receptor alpha antagonist. “Many people refer to IL-31 as the itch cytokine,” Dr. Rosmarin said. “That’s probably a little oversimplified, but it’s certainly a powerful medication in development for prurigo nodularis as well as AD.”

Dr. Rosmarin

Results from the ARCADIA 1 and 2 trials, which included the concurrent use of topical corticosteroids and calcineurin inhibitors and were presented as an abstract at the 2023 EADV meeting, showed that nemolizumab significantly improved skin lesions and itch in adolescent and adult patients with moderate to severe atopic dermatitis, compared with placebo. Specifically, 35.6% and 37.7% of nemolizumab-treated patients in ARCADIA 1 and 2, respectively, reached clearance or almost-clearance of skin lesions when assessed using the IGA score, compared with 24.6% and 26.0% in the placebo group (P < .0006, P = .001). In addition, 43.5% and 42.1% of nemolizumab-treated patients in ARCADIA 1 and 2, respectively, achieved a 75% reduction in the EASI, compared with 29.0% and 30.2% in the placebo group (P < .0001, P = .0011). “There are similar results regardless of the degree of itch patients are starting out with at baseline,” Dr. Rosmarin said. “It’s a very rapid response, by week 4, and that continues to improve through week 16.”

Amlitelimab. Under development by Sanofi, this monoclonal antibody binds to OX40-Ligand, and is designed for patients with moderate to severe AD. According to results of a phase 2b trial that were presented in an abstract at the 2023 EADV meeting, patients treated with amlitelimab 250 mg Q4W with a 500 mg loading dose showed a 61.5% improvement in the average EASI score from baseline at week 16, compared with 29.4% of those who received placebo (P <.0001), with continued improvement seen through 24 weeks. “There are really strong results with EASI scores; clearly this medicine works compared to the placebo,” Dr. Rosmarin said. “It’s also improving other biomarkers as well, including eosinophils, IL-13, TARC [serum thymus and activation-regulated chemokine], and IL-22.”

138559 (Temtokibart). Under development by LEO, 138559 is the first biologic to show the efficacy and safety of an IL-22RA1 targeting antibody for the treatment of moderate-to-severe AD. In a phase 2a study abstract presented at the 2023 EADV meeting, the mean change in EASI from baseline to Week 16 was significantly greater for patients in the 138559-treated group compared with those in the placebo group (–15.3 vs. –3.5; P = .003). In addition, at week 16, significantly greater proportions of patients in the 138559 group relative to those in the placebo group achieved an EASI75 score (41.6% vs. 13.7%; P = .011) and an EASI-90 score (30.8% vs. 3.5%; P = .003). “With this particular receptor you’re not only blocking IL-22, but you’re blocking IL-20 and IL-24 as well,” Dr. Rosmarin said. “It really may be that it’s IL-20 and IL-24 that are more responsible for the pathogenic effect.”

Dr. Rosmarin disclosed that he is speaker for and/or a consultant and advisory board member to many pharmaceutical companies, including Galderma and Sanofi.

TOPLINE:

Nearly half of the US Food and Drug Administration (FDA) approvals for dermatologic drugs between 2012 and 2022 were considered first in class or first in indication.

METHODOLOGY:

• Only five new drugs for diseases treated mostly by dermatologists were approved by the FDA between 1999 and 2009.
• In a cross-sectional analysis to characterize the frequency and degree of innovation of dermatologic drugs approved more recently, researchers identified new and supplemental dermatologic drugs approved between January 1, 2012, and December 31, 2022, from FDA lists, Centers for Medicare & Medicaid Services CenterWatch, and peer-reviewed articles.
• They used five proxy measures to estimate each drug’s degree of innovation: FDA designation (first in class, advance in class, or addition to class), independent clinical usefulness ratings, and benefit ratings by health technology assessment organizations.

TAKEAWAY:

• The study authors identified 52 new drug applications and 26 supplemental new indications approved by the FDA for dermatologic indications between 2012 and 2022.
• Of the 52 new drugs, the researchers categorized 11 (21%) as first in class and 13 (25%) as first in indication.
• An analysis of benefit ratings available for 38 of the drugs showed that 15 (39%) were rated as being clinically useful or having high added therapeutic benefit.
• Of the 10 supplemental new indications with ratings by any organization, 3 (30%) were rated as clinically useful or having high added therapeutic benefit.

IN PRACTICE:

While innovative drug development in dermatology may have increased, “these findings also highlight opportunities to develop more truly innovative dermatologic agents, particularly for diseases with unmet therapeutic need,” the authors wrote.

First author Samir Kamat, MD, of the Medical Education Department at Icahn School of Medicine at Mount Sinai, New York City, and corresponding author Ravi Gupta, MD, MSHP, of the Internal Medicine Division at Johns Hopkins University, Baltimore, Maryland, led the research. The study was published online as a research letter on December 20, 2023, in JAMA Dermatology.

LIMITATIONS:

They include the use of individual indications to assess clinical usefulness and benefit ratings. Many drugs, particularly supplemental indications, lacked such ratings. Reformulations of already marketed drugs or indications were not included.

DISCLOSURES:

Dr. Kamat and Dr. Gupta had no relevant disclosures. Three coauthors reported having received financial support outside of the submitted work.

The myriad of clinical tools available for assessing patients with atopic dermatitis may leave clinicians wondering how to best incorporate the tools into the daily clinical workflow.

“It can be overwhelming because there are many choices but so little time,” Jonathan I. Silverberg, MD, PhD, MPH, associate professor and director of clinical research in the dermatology department at George Washington University, Washington, DC, said at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.

Assessment tools such as the Eczema Area and Severity Index (EASI), the Numeric Rating scale for itch (NRS-itch), and the Dermatology Life Quality Index (DLQI) “all correlate, but they’re all different, and there is value in all of them,” said Dr. Silverberg. “Of course, you’re not going to use all of them, but which ones should you use?”

He favors a structured approach that considers signs, symptoms, and quality of life, a framework that he and Shanthi Narla, MD, proposed in an article published online in Dermatitis. In the United States, he said, the Investigator’s Global Assessment scale (IGA) and BSA are the preferred tools for assessing the clinical severity of AD.

“If you go to Australia and New Zealand, they love EASI, while in Western Europe, they love the SCORAD [SCORing Atopic Dermatitis] tool because they’ve been using it since the 1990s,” Dr. Silverberg said. “So whatever works for you, pick it. But just use something that’s going to work within your practice setting. The IGA and the BSA are the easiest to do and the fastest to do in clinical practice. You’re going to have to document disease severity anyway if you’re going to get systemic therapies approved,” he said, referring to approval for coverage by the patient’s health insurance drug formulary.
 

Several Recommendations

Based on his clinical experience, Dr. Silverberg recommended certain assessment tools as “feasible” to use in daily practice. In the domain of clinical signs, “the IGA and the BSA are the most useful,” he said. “If the patient is gowned up, it probably takes about 30 seconds to do an IGA scale, and a BSA can be done in under a minute, easily.”

In the domain of symptoms, he recommends having the patient or caregiver complete at least one of the following patient-reported outcome measures (PROMs): the NRS-itch, the NRS-pain, the NRS-Sleep Disturbance, the Patient Health Questionnaire-2 (PHQ-2), and either the Patient Global Assessment (PtGA) or the Patient-Reported Global AD Severity (PrtGA).

“Pick one or two that reflect what you can do in clinical practice,” Dr. Silverberg advised. “The NRS-itch is clinically meaningful and takes 10 seconds to do. Or you can just ask the patient, ‘How do you rate your itch? Clear, mild, moderate, or severe?’ A verbal rating scale, like a Likert scale, would also work. Again, this takes 10 seconds to assess. This is not slowing you down in practice; it will speed you up in the long run.”

He favors the NRS scale assessments, “because the 2023 AAD guidelines for AD advocate for open-ended questions,” he said. “I can tell you from personal experience that when you go down that rabbit hole of open-ended questions, you’re never getting out of that exam room. If you ask a patient how AD affects their life, you might as well just plan on a 30- to 40-minute visit. But if you use structured questions, you can get the information you need so dearly to make the right assessments, but you can keep the visit moving efficiently.”

He noted that the NRS-itch or the PtGA and PrtGA tools “each take about 10 seconds to complete. I would argue that you could probably have the patient [complete all of these PROMs], and you’re still in under a minute, and you get incredibly rich information.”

In the quality-of-life domain, Dr. Silverberg recommends that the patient or caregiver complete the DLQI. If there is additional time, he also suggests the Atopic Dermatitis Control Tool (ADCT) to gain further insight on symptomatology.

“The DLQI takes about a minute or minute-and-a-half to complete, while the ADCT takes about a minute,” he said. “It measures overall disease control, and there are some interesting individual questions there, such as how AD bothers them, how it impacts their sleep, how it impacts them emotionally.”

To optimize efficiency, Dr. Silverberg recommends that patients or caregivers complete PROMs prior to the patient encounter by e-mail or on the patient’s online portal the night before. Freely available smart phone applications designed for AD patients can help them track their disease symptoms, such as EczemaWise from the National Eczema Association.

“[The PROMs] can even be completed in the waiting area; a lot of times we’re running behind anyway,” he said. “Even if we’re not, it can be done in a minute or two while they’re filling out their insurance paperwork or whatever. Patient-reported outcomes can also be collected by the medical assistant or nursing while rooming the patient.”

Administering such structured assessments prior to the actual patient encounter “seems counterintuitive because you’re asking seemingly more information, but that doesn’t matter, because you are asking it in an efficient, structured manner, and you are getting the information you need,” he noted. “These tools can also help fill in the gaps of telehealth encounters.”

Dr. Silverberg reported being a consultant and/or an adviser for many pharmaceutical companies. He has also received grant or research support from Galderma and Pfizer.

The myriad of clinical tools available for assessing patients with atopic dermatitis may leave clinicians wondering how to best incorporate the tools into the daily clinical workflow.

“It can be overwhelming because there are many choices but so little time,” Jonathan I. Silverberg, MD, PhD, MPH, associate professor and director of clinical research in the dermatology department at George Washington University, Washington, DC, said at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.

Assessment tools such as the Eczema Area and Severity Index (EASI), the Numeric Rating scale for itch (NRS-itch), and the Dermatology Life Quality Index (DLQI) “all correlate, but they’re all different, and there is value in all of them,” said Dr. Silverberg. “Of course, you’re not going to use all of them, but which ones should you use?”

He favors a structured approach that considers signs, symptoms, and quality of life, a framework that he and Shanthi Narla, MD, proposed in an article published online in Dermatitis. In the United States, he said, the Investigator’s Global Assessment scale (IGA) and BSA are the preferred tools for assessing the clinical severity of AD.

“If you go to Australia and New Zealand, they love EASI, while in Western Europe, they love the SCORAD [SCORing Atopic Dermatitis] tool because they’ve been using it since the 1990s,” Dr. Silverberg said. “So whatever works for you, pick it. But just use something that’s going to work within your practice setting. The IGA and the BSA are the easiest to do and the fastest to do in clinical practice. You’re going to have to document disease severity anyway if you’re going to get systemic therapies approved,” he said, referring to approval for coverage by the patient’s health insurance drug formulary.
 

Several Recommendations

Based on his clinical experience, Dr. Silverberg recommended certain assessment tools as “feasible” to use in daily practice. In the domain of clinical signs, “the IGA and the BSA are the most useful,” he said. “If the patient is gowned up, it probably takes about 30 seconds to do an IGA scale, and a BSA can be done in under a minute, easily.”

In the domain of symptoms, he recommends having the patient or caregiver complete at least one of the following patient-reported outcome measures (PROMs): the NRS-itch, the NRS-pain, the NRS-Sleep Disturbance, the Patient Health Questionnaire-2 (PHQ-2), and either the Patient Global Assessment (PtGA) or the Patient-Reported Global AD Severity (PrtGA).

“Pick one or two that reflect what you can do in clinical practice,” Dr. Silverberg advised. “The NRS-itch is clinically meaningful and takes 10 seconds to do. Or you can just ask the patient, ‘How do you rate your itch? Clear, mild, moderate, or severe?’ A verbal rating scale, like a Likert scale, would also work. Again, this takes 10 seconds to assess. This is not slowing you down in practice; it will speed you up in the long run.”

He favors the NRS scale assessments, “because the 2023 AAD guidelines for AD advocate for open-ended questions,” he said. “I can tell you from personal experience that when you go down that rabbit hole of open-ended questions, you’re never getting out of that exam room. If you ask a patient how AD affects their life, you might as well just plan on a 30- to 40-minute visit. But if you use structured questions, you can get the information you need so dearly to make the right assessments, but you can keep the visit moving efficiently.”

He noted that the NRS-itch or the PtGA and PrtGA tools “each take about 10 seconds to complete. I would argue that you could probably have the patient [complete all of these PROMs], and you’re still in under a minute, and you get incredibly rich information.”

An experimental topical phosphodiesterase 4 (PDE4) inhibitor showed superior efficacy to vehicle in patients with mild to moderate atopic dermatitis (AD) and plaque psoriasis, results from a phase 2a study showed.

PDE4 inhibitors are a promising therapeutic target for inflammatory diseases because “they can increase cyclic adenosine monophosphate levels and subsequently reduce the production of proinflammatory cytokines,” lead study author Lawrence F. Eichenfield, MD, of the dermatology department at the University of California, San Diego, and colleagues wrote. The paper was published online in JAMA Dermatology.

Currently Available Treatments

For plaque psoriasis, the FDA approved the topical PDE4 inhibitor roflumilast in 2022. The oral PDE4 inhibitor apremilast has shown to be effective for plaque psoriasis and is well tolerated, and “it has been associated with gastrointestinal adverse events (AEs) such as nausea and diarrhea,” the researchers wrote.

For AD, crisaborole is the only approved topical PDE4 treatment, and it is associated with application site burning and stinging, they wrote.

An Experimental Alternative

The new study tested a topical PDE4 inhibitor known as PF-07038124, which is being developed by Pfizer. It is designed to be “a potent, oxaborole-based PDE4 inhibitor [that shows] immunomodulatory activity in T-cell–based assays, contributing to inhibition of [interleukin]-4 and IL-13; thus, it could provide therapeutic benefit in the treatment of AD and plaque psoriasis,” the authors wrote.

The phase 2a study was conducted from December 21, 2020, to August 18, 2021. Researchers at 34 sites in four countries randomized 104 patients with mild to moderate AD (70) or plaque psoriasis (34) to receive PF-07038124 as a 0.001% topical ointment or a vehicle only once daily for 6 weeks.

The primary end point was the percent change from baseline in the Eczema Area and Severity Index (EASI) total score among patients with AD and in the Psoriasis Area and Severity Index (PASI) score among patients with plaque psoriasis at week 6. Safety measures of interest included treatment-emergent adverse events.

Overall, the mean age of the 104 patients was 43 years, 52.9%, were women, 3.8% were Asian, 12.5% were Black, and 83.7% were White. Most had moderate disease.

At week 6 in patients with AD, the PF-07038124 group showed statistically significantly greater improvement in the EASI total score, compared with vehicle group (−74.9% vs −35.5% respectively; least squares mean [LSM] difference, −39.4%; 90% CI, −58.8% to−20.1%]; P < .001).

Similarly, at week 6 in patients with plaque psoriasis, the PF-07038124 group demonstrated a significantly greater improvement in the PASI total score, compared with the vehicle group (LSM, −4.8; 90% CI, −6.2 to −3.4] vs 0.1; 90% CI, −1.5 to 1.7), for a difference of −4.9; 90% CI, −7.0 to −2.8; P < .001.

In safety outcomes, treatment-emergent adverse events were reported in 16 people receiving PF-07038124 and 26 people receiving a vehicle. The treatment-related adverse events were reported only in the vehicle groups across all indications, while no patients in the PF-07038124 groups experienced pain or skin reactions at the application sites.

The researchers acknowledged certain limitations of the trial, including its small size and the 6-week treatment period. “Unlike crisaborole, topical PF-07038124 was not associated with application site burning and stinging,” they noted. “To confirm persistence of efficacy and the safety profile of PF-07038124, long-term data should be collected in larger studies.”

Pfizer supported the study. Dr. Eichenfield reported receiving personal fees from Pfizer during the conduct of the study. He also has received grant support from, is consultant to, and/or is a member of the advisory board for many other pharmaceutical companies. Several other study authors reported similar disclosures.
