Intranasal butorphanol effectively rescues from intractable itch in retrospective study
Shawn G. Kwatra, MD, reported at the virtual annual meeting of the American Academy of Dermatology.
Dr. Kwatra, a dermatologist at Johns Hopkins University, Baltimore, where he heads a specialized pruritus clinic, presented a retrospective study of 16 such patients treated with inhaled butorphanol. All had been responsive to a minimum of four antipruritic medications.
This is one of the largest-ever reported series of patients treated with intranasal butorphanol as acute rescue therapy for intractable itch, and it provides a strong signal of efficacy, he said in an interview.
Indeed, 11 of the 16 patients reported marked improvement in their itch after introduction of short-term treatment with butorphanol nasal spray, 1 reported no improvement, and 4 were lost to follow-up.
Itch, Dermatology Life Quality Index (DLQI), and Beck Depression Inventory scores were formally measured prior to introduction of short-term inhaled butorphanol and again at follow-up appointments at 4-6 weeks. The mean self-reported itch numeric rating scale score improved from a mean of 9.8 out of a possible 10 at baseline to 4.6 at follow-up. The reduction in itch was accompanied by major improvements in quality of life: the mean DLQI score dropped from 20.2 to 10.8, while the Beck Depression Inventory score went from 22.1 – typically interpreted as an indicator of moderate depression – to 14.2.
Three patients reported insomnia and/or lightheadedness they attributed to inhaled butorphanol.
The patients with chronic refractory itch had a wide range of associated underlying diagnoses. These included primary sclerosing cholangitis, trigeminal trophic syndrome, brachioradial pruritus, neuropathic pruritus, prurigo nodularis, chronic idiopathic urticaria, chronic aquagenic pruritus, atopic dermatitis, and itch induced by programmed death–1 immune checkpoint inhibitor therapy. It will take large randomized, controlled trials to determine which of these types of chronic pruritus benefit most from intranasal butorphanol, according to Dr. Kwatra.
Since butorphanol is a narcotic analgesic ill-suited to applications other than as short-term acute rescue therapy, there is a pressing unmet need for new therapies specifically targeting chronic itch as a symptom, he added. Several promising agents are advancing through the drug development pipeline.
Dr. Kwatra reported having no financial conflicts regarding this study, conducted free of commercial support.

For urban-based African Americans, proximity to a dermatologist varies by ZIP code
Urban ZIP codes with higher percentages of African American people tend to have fewer dermatologists. In these areas, dermatologists are not able meet the populations’ needs, based on the suggested ratio of patients per dermatologist.
The findings come from an analysis which used U.S. Census data to compare dermatologists’ distribution in urban ZIP codes with high and low representation of African Americans.
“It has been demonstrated that there is a non-uniform geographic distribution of dermatologists, in which they tend to practice in urban settings,” the study’s first author, Nathan Vengalil, MD, said in an interview following the virtual annual meeting of the American Academy of Dermatology. “Furthermore, it is also an unfortunate reality that African Americans suffer from inferior access to care compared to whites across health care. The same is true within dermatology; for example, African Americans face higher morbidity and mortality from melanoma, compared to their white counterparts.”
For the current study, Dr. Vengalil, a recent graduate of the University of Michigan, Ann Arbor, and associates in the university’s department of dermatology drew from 2010 U.S. Census data to identify ZIP codes with populations of 25,000 people and greater, because these should have at least one dermatologist to care for a community of that size (JAMA Dermatology 2017;153[5]:472-3).
Next, they ordered these ZIP codes from low to high concentrations of African American people. Those that fell in the 15th percentile or fewer were categorized as “low” (a total of 370 ZIP codes), while those that fell in the 85th percentile or higher were categorized as “high” (a total of 443 ZIP codes). Following this, the Definitive Healthcare provider database was used to identify the number of dermatologists practicing within each ZIP code and to calculate the average number of people per dermatologist in the “low” and “high” categories.
The researchers found that ZIP codes with high percentage of African American people have an average of 1.02 dermatologists (1 per 39,367 people), which is below the recommended limit of 1 per 25,000 people. Meanwhile, ZIP codes with a low percentage of African American people averaged 2.84 dermatologists (1 per 14,000 people), which is above the adequate limit. “ZIP codes with a low percentage of African Americans had, on average, almost three times more dermatologists than ZIP codes with a high percentage of American Americans,” Dr. Vengalil said. “This means that predominantly African American urban communities may face consequences of low provider availability including longer waits times, decreased diagnosis of skin cancer, and worse health care outcomes.”
He acknowledged certain limitations of the study, including the fact that it focused only on the distribution of dermatologists to assess communities’ access to dermatologic care. “It would be interesting to measure how much mid-level providers such as nurse practitioners and physician assistants are able to compensate for the low number of dermatologists in urban ZIP codes with high numbers of African Americans,” Dr. Vengalil said.
The study’s findings suggest that the distribution of dermatologists is not uniform even within the urban environment, especially when comparing areas with different representations of African American persons. “This reveals that lack of provider proximity may contribute to barriers that urban African Americans face in accessing dermatologic care,” he concluded. “Looking toward the future, it will be important to incentivize the development of practice locations in urban African American communities to combat the health disparities of our most underserved patients.”
The study’s other authors were Mio Nakamura, MD, MS, and Yolanda Helfrich, MD. The researchers reported having no financial disclosures.

Increased hypothyroidism risk seen in young men with HS
Anna Figueiredo, MD, declared at the virtual annual meeting of the American Academy of Dermatology.
The surprise about this finding from a large retrospective case-control study stems from the fact that the elevated risk for hypothyroidism didn’t also extend to younger women with hidradenitis suppurativa (HS) nor to patients older than 40 years of either gender, explained Dr. Figueiredo of the department of dermatology at Northwestern University, Chicago.
She presented a retrospective case-control study based on information extracted from a medical records database of more than 8 million Midwestern adults. Among nearly 141,000 dermatology patients with follow-up in the database for at least 1 year, there were 405 HS patients aged 18-40 years and 327 aged 41-89.
In an age-matched comparison with the dermatology patients without HS, the younger HS cohort was at a significant 1.52-fold increased risk for comorbid hypothyroidism. Upon further stratification by sex, only the younger men with HS were at increased risk. Those patients were at 3.95-fold greater risk for having a diagnosis of hypothyroidism than were age-matched younger male dermatology patients.
Both younger and older HS patients were at numerically increased risk for being diagnosed with hyperthyroidism; however, this difference didn’t approach statistical significance because there were so few cases: a total of just eight in the HS population across the full age spectrum.
Hidradenitis suppurativa is a chronic inflammatory disease with an estimated prevalence of up to 4% in the United States. Growing evidence suggests it is an immune-mediated disorder because the tumor necrosis factor inhibitor adalimumab (Humira) has been approved for treatment of HS.
Thyroid disease is also often autoimmune-mediated, but its relationship with HS hasn’t been extensively examined. A recent meta-analysis of five case-control studies concluded that HS was associated with a 1.36-fold increased risk of thyroid disease; however, the Nepalese investigators didn’t distinguish between hypo- and hyperthyroidism (J Am Acad Dermatol. 2020 Feb;82[2]:491-3).
Dr. Figueiredo reported having no financial conflicts regarding her study, which was without commercial support.

More phase 3 data reported for abrocitinib for atopic dermatitis
Melinda Gooderham, MD, reported at the virtual annual meeting of the American Academy of Dermatology.
The positive results of this 391-patient, international, randomized, double-blind, placebo-controlled clinical trial mirror those previously reported in the identically designed JADE-MONO-1 pivotal phase 3 trial, noted Dr. Gooderham, medical director of the SKiN Centre for Dermatology and a dermatologist at Queen’s University in Kingston, Ont.
Participants in JADE-MONO-2 were randomized 2:2:1 to abrocitinib at 200 mg once daily, 100 mg once daily, or placebo for 12 weeks. The coprimary endpoint of skin clearance as reflected in an Investigator’s Global Assessment (IGA) score of 0 or 1 (clear or almost clear) with an improvement of at least two grades at week 12 was achieved in 38.1% and 28.4% of patients on 200 and 100 mg of the JAK-1 inhibitor, respectively, compared with 9.1% of placebo-treated controls. The other coprimary endpoint – significant improvement in disease extent as defined by at least a 75% reduction from baseline in Eczema Area and Severity Index (EASI-75 response) at 12 weeks – was reached in 61% of patients on abrocitinib at 200 mg/day, 44.5% on 100 mg/day, and 10.4% of controls.
A key secondary endpoint was improvement in itch based on at least a 4-point improvement at week 12 on the Peak Pruritus Numerical Rating Scale from a mean baseline score of 7. This outcome was reached by 55.3% of patients on abrocitinib at 200 mg, 45.2% on 100 mg, and 11.5% on placebo. Of note, the reduction in itch was impressively fast, with significant separation from placebo occurring within the first 24 hours of the study, after just a single dose of abrocitinib. By week 2, roughly one-third of patients on high-dose and one-quarter of those on low-dose abrocitinib had already reached the itch endpoint, the dermatologist continued.
The improvement in pruritus scores in abrocitinib-treated patients was accompanied by significantly greater gains on validated measures of quality of life, another secondary endpoint. The EASI-90 response rate, yet another key secondary outcome, was 37.7% with abrocitinib at 200 mg, 23.9% with 100 mg, and 3.9% with placebo.
The safety profile of abrocitinib was essentially the same as for placebo with the exception of a 3.2% incidence of thrombocytopenia in patients on abrocitinib at 200 mg/day; no cases occurred in controls or patients on abrocitinib at 100 mg/day. Although venous thromboembolism has arisen as a potential concern in clinical trials of oral JAK inhibitors for rheumatoid arthritis, there were no cases in JADE-MONO-2. A long-term safety extension study in JADE-MONO participants is underway.
In an interview, Dr. Gooderham said that, based on the phase 2 study data that’s available for upadacitinib, another JAK-1-selective oral agent, abrocitinib and upadacitinib appear to be in the same ballpark with respect to efficacy as defined by IGA response, EASI improvement, and itch relief.
“The JAK-1 selectivity does seem to offer some advantage in levels of response over more broad JAK inhibition, such as with baritinib,” she added.
Asked how she foresees abrocitinib fitting into clinical practice, should it win regulatory approval for treatment of atopic dermatitis, Dr. Gooderham said it might be considered on a par with the injectable interleukin-4 and -13 inhibitor dupilumab (Dupixent) as next-line therapy after failure on topical therapy or as an option in patients who haven’t responded to or could not tolerate dupilumab. Abrocitinib will be an attractive option for patients who prefer oral therapy and will be an especially appealing medication in patients with a strong itch component to their atopic dermatitis, she added.
The results of JADE COMPARE, a phase 3, head-to-head randomized comparison of abrocitinib and dupilumab, are expected to be presented later this year at the virtual annual congress of the European Academy of Dermatology and Venereology. Pfizer has announced the key results, reporting that the JAK inhibitor at 200 mg/day achieved significantly greater improvements than dupilumab in the coprimary IGA and EASI-75 endpoints at 12 weeks.
JADE-MONO-2 was sponsored by Pfizer. Dr. Gooderham reported receiving research grants from that company and close to two dozen others.
The JADE-MONO-2 results have been published online (JAMA Dermatol. 2020 Jun 3;e201406. doi: 10.1001/jamadermatol.2020.1406).

The JADE-MONO-2 results have been published online (JAMA Dermatol. 2020 Jun 3;e201406. doi: 10.1001/jamadermatol.2020.1406).
Melinda Gooderham, MD, reported at the virtual annual meeting of the American Academy of Dermatology.
The positive results of this 391-patient, international, randomized, double-blind, placebo-controlled clinical trial mirror those previously reported in the identically designed JADE-MONO-1 pivotal phase 3 trial, noted Dr. Gooderham, medical director of the SKiN Centre for Dermatology and a dermatologist at Queen’s University in Kingston, Ont.
Participants in JADE-MONO-2 were randomized 2:2:1 to abrocitinib at 200 mg once daily, 100 mg once daily, or placebo for 12 weeks. The coprimary endpoint of skin clearance as reflected in an Investigator’s Global Assessment (IGA) score of 0 or 1 (clear or almost clear) with an improvement of at least two grades at week 12 was achieved in 38.1% and 28.4% of patients on 200 and 100 mg of the JAK-1 inhibitor, respectively, compared with 9.1% of placebo-treated controls. The other coprimary endpoint – significant improvement in disease extent as defined by at least a 75% reduction from baseline in Eczema Area and Severity Index (EASI-75 response) at 12 weeks – was reached in 61% of patients on abrocitinib at 200 mg/day, 44.5% on 100 mg/day, and 10.4% of controls.
A key secondary endpoint was improvement in itch based on at least a 4-point improvement at week 12 on the Peak Pruritus Numerical Rating Scale from a mean baseline score of 7. This outcome was reached by 55.3% of patients on abrocitinib at 200 mg, 45.2% on 100 mg, and 11.5% on placebo. Of note, the reduction in itch was impressively fast, with significant separation from placebo occurring within the first 24 hours of the study, after just a single dose of abrocitinib. By week 2, roughly one-third of patients on high-dose and one-quarter of those on low-dose abrocitinib had already reached the itch endpoint, the dermatologist continued.
The improvement in pruritus scores in abrocitinib-treated patients was accompanied by significantly greater gains on validated measures of quality of life, another secondary endpoint. The EASI-90 response rate, yet another key secondary outcome, was 37.7% with abrocitinib at 200 mg, 23.9% with 100 mg, and 3.9% with placebo.
The safety profile of abrocitinib was essentially the same as for placebo with the exception of a 3.2% incidence of thrombocytopenia in patients on abrocitinib at 200 mg/day; no cases occurred in controls or patients on abrocitinib at 100 mg/day. Although venous thromboembolism has arisen as a potential concern in clinical trials of oral JAK inhibitors for rheumatoid arthritis, there were no cases in JADE-MONO-2. A long-term safety extension study in JADE-MONO participants is underway.
In an interview, Dr. Gooderham said that, based on the phase 2 study data that’s available for upadacitinib, another JAK-1-selective oral agent, abrocitinib and upadacitinib appear to be in the same ballpark with respect to efficacy as defined by IGA response, EASI improvement, and itch relief.
“The JAK-1 selectivity does seem to offer some advantage in levels of response over more broad JAK inhibition, such as with baritinib,” she added.
Asked how she foresees abrocitinib fitting into clinical practice, should it win regulatory approval for treatment of atopic dermatitis, Dr. Gooderham said it might be considered on a par with the injectable interleukin-4 and -13 inhibitor dupilumab (Dupixent) as next-line therapy after failure on topical therapy or as an option in patients who haven’t responded to or could not tolerate dupilumab. Abrocitinib will be an attractive option for patients who prefer oral therapy and will be an especially appealing medication in patients with a strong itch component to their atopic dermatitis, she added.
The results of JADE COMPARE, a phase 3, head-to-head randomized comparison of abrocitinib and dupilumab, are expected to be presented later this year at the virtual annual congress of the European Academy of Dermatology and Venereology. Pfizer has announced the key results, reporting that the JAK inhibitor at 200 mg/day achieved significantly greater improvements than dupilumab in the coprimary IGA and EASI-75 endpoints at 12 weeks.

Vulvar melanoma is increasing in older women
Maia K. Erickson reported in a poster at the virtual annual meeting of the American Academy of Dermatology.
These are often aggressive malignancies. The 5-year survival following diagnosis of vulvar melanoma in women aged 60 years or older was 39.7%, compared with 61.9% in younger women, according to Ms. Erickson, a visiting research fellow in the department of dermatology at Northwestern University, Chicago.
She presented a population-based study of epidemiologic trends in vulvar melanoma based upon analysis of the National Cancer Institute’s Surveillance, Epidemiology and End Results database. Vulvar melanoma was rare during the study years 2000-2016, with an overall incidence rate of 0.1 cases per 100,000 women. That worked out to 746 analyzable cases. Of note, the incidence rate ratio was 680% higher in older women (age 60 and older).
One reason for the markedly worse 5-year survival in older women was that the predominant histologic subtype of vulvar melanoma in that population was nodular melanoma, accounting for 48% of the cases where a histologic subtype was specified. In contrast, the less-aggressive superficial spreading melanoma subtype prevailed in patients aged under 60 years, accounting for 63% of cases.
About 93% of vulvar melanomas occurred in whites; 63% were local and 8.7% were metastatic.
Ms. Erickson noted that the vulva is the most common site for gynecologic tract melanomas, accounting for 70% of them. And while the female genitalia make up only 1%-2% of body surface area, that’s the anatomic site of up to 7% of all melanomas in women.
She reported having no financial conflicts regarding her study.

Study compares pulse vs. continuous therapy for dermatophyte toenail onychomycosis
There appear to be results from a systematic review and network meta-analysis showed.
“Previous meta-analyses of pulse and continuous therapies have generated ambiguous results,” study authors led by Aditya K. Gupta, MD, PhD, wrote in a poster abstract presented at the virtual annual meeting of the American Academy of Dermatology. “There are few head-to-head clinical studies and no meta-analyses comparing regimens of terbinafine to regimens of itraconazole.”
In what is believed to be the first study of its kind, Dr. Gupta, professor of dermatology at the University of Toronto, and colleagues used network meta-analysis to compare pulse and continuous systemic therapies for toenail onychomycosis. They used PubMed to search for randomized, controlled trials of oral antifungal treatments for the condition in patients aged 18 years and older that included data on mycologic cure, complete cure, adverse events, and dropout rates. Treatment effects were based on intention-to-treat cure rates, and the researchers excluded studies of ketoconazole and griseofulvin since they are no longer indicated for the condition.
For their network meta-analysis, Dr. Gupta and colleagues evaluated 22 studies from 20 publications that included 4,205 randomized patients. Data on complete cure were excluded because of a lack of studies. When the researchers compared all treatments to placebo, the likelihood of mycologic cure did not differ significantly between continuous and pulse regimens for terbinafine and itraconazole. Compared with placebo, the most successful treatments were continuous terbinafine 250 mg daily for 24 weeks (risk ratio of achieving mycologic cure, 11.0) and continuous terbinafine 250 mg daily for 16 weeks (RR, 8.90). The researchers also observed no significant differences in the likelihood of adverse events between any continuous and pulse regimens of terbinafine, itraconazole, and fluconazole.
“Although continuous terbinafine 250 mg for 24 weeks was significantly more likely to produce mycologic cure than continuous itraconazole 200 mg for 12 weeks and weekly fluconazole (150-450 mg), it is not significantly different from the other included treatments,” Dr. Gupta and colleagues wrote in the abstract. “Considering the fungal life cycle, pulse therapy should theoretically be as effective as, or more effective than, continuous therapies: the sudden high concentration of an antifungal drug eliminates hyphae, sparing already-present spores. During the ‘off’ portion, these spores may germinate and be eliminated during the next pulse. Continuous therapy spares the spores, allowing them to germinate once treatment ends.”
They went on to note that, in clinical practice, “neither continuous nor pulse therapy is necessarily better. It is possible that the drug concentration in the nail is maintained during the ‘off’ period of pulse therapy. In both therapies, it may be that residual spores that have not been eliminated by the end of therapy are left to germinate, possibly contributing to the recalcitrant nature of onychomycosis.”
The study was awarded fourth place in the AAD’s 2020 poster awards. Dr. Gupta disclosed that he is a clinical trials investigator for Moberg Pharma and Bausch Health Canada and a speaker for Bausch Health Canada.

Tralokinumab found effective in phase 3 atopic dermatitis studies
presented at the virtual annual meeting of the American Academy of Dermatology.
Tralokinumab is a fully human monoclonal antibody which binds specifically to interleukin-13 and thereby prevents downstream IL-13 signaling. In contrast, dupilumab (Dupixent), at present the only approved biologic agent for AD, blocks both the IL-13 and IL-4 pathways.
Two of the pivotal phase 3 trials presented at AAD 2020 – ECZTRA 1 and ECZTRA 2 – were identically designed, randomized, double-blind, placebo-controlled, 52-week, multinational monotherapy studies including a collective 1,596 adults with moderate to severe AD. In contrast, ECZTRA 3 was a 380-patient, double-blind, randomized, 32-week study of tralokinumab in combination with a topical corticosteroid versus placebo injections plus a topical corticosteroid.
“I would say the take-home point of these trials is they are proof of principle that blocking just IL-13 can be an effective approach. The studies help us understand that IL-13 is an important driver cytokine for the disease,” Eric Simpson, MD, lead clinical investigator for ECZTRA 2, said in an interview.
In all three phase 3 trials, the primary endpoint was achievement of a clinical response as defined by an Investigator Global Assessment score of clear or almost clear skin (IGA 0/1) plus at least a 75% improvement in the Eczema Area and Severity Index score (EASI-75) at week 16. In ECZTRA 1 and 2, this was accomplished in 16% and 22% of patients on 300 mg of tralokinumab administered subcutaneously every 2 weeks, compared with 7% and 11% of placebo-treated controls.
Patients with a clinical response at week 16 were then rerandomized to tralokinumab either every other week or every 4 weeks or to placebo for an additional 36 weeks. At 52 weeks, 51% and 59% of patients in ECZTRA 1 and 2, respectively, who had a clinical response at week 16 maintained an IGA 0/1 response while on tralokinumab every 2 weeks, as did 39% and 45% of those switched to treatment every 4 weeks. Similarly, 60% and 56% of clinical responders at week 16 maintained an EASI-75 response at week 52 with tralokinumab every 2 weeks, as did 49% and 51% of those rerandomized to treatment every 4 weeks.
The safety profile of tralokinumab in the two monotherapy trials was comparable with placebo.
In the ECZTRA studies, tralokinumab achieved significant improvement at week 16 in secondary endpoints including itch, health-related quality of life, and severity and extent of skin lesions.
How does tralokinumab, with its narrower focus targeting a single cytokine, stack up against dupilumab, the dual IL-13/IL-4 inhibitor that’s transformed the treatment of patients with moderate or severe AD?
Dr. Simpson, who was also principal investigator in a pivotal phase 3 trial for dupilumab, emphasized that no firm conclusions can be drawn because there have been no head-to-head comparative trials and the tralokinumab and dupilumab trials had different patient populations, geographic locations, and washout periods. With those caveats, however, he commented that, “just on the surface, numerically, for the monotherapy studies, dupilumab hit some higher targets than tralokinumab in terms of the percentage of patients clear or almost clear.”
In terms of safety, it appears that the risk of conjunctivitis may be lower with tralokinumab than dupilumab, with rates of 7% and 3% through 52 weeks in ECZTRA 1 and 2, respectively, versus 2% with placebo, although again this is “a caveated conclusion,” said Dr. Simpson, professor of dermatology at Oregon Health and Science University, Portland.
Tralokinumab combination therapy in ECZTRA 3
At 16 weeks, 39% of patients treated with tralokinumab plus topical corticosteroids had an IGA of 0/1 and 56% had an EASI-75 response, compared with 26% and 36% of patients on topical corticosteroids plus biweekly placebo injections. More than 90% of patients with a good clinical response at week 16 maintained that response at week 32 while on tralokinumab biweekly plus topical steroids. Among good responders at week 16 who were rerandomized to 300 mg of tralokinumab every 4 weeks plus topical steroids, 78% still had an IGA of 0/1 at week 32, and 91% had an EASI-75, reported Jonathan I. Silverberg, MD, PhD, director of clinical research and contact dermatitis at George Washington University, Washington.
A randomized, placebo-controlled combination therapy study such as this provides information that’s especially useful in clinical practice, Dr. Simpson observed.
“When I’m talking to patients about any biologics or oral therapies, I usually quote the figures from the combination therapy studies because the vast majority of our patients are using topical therapy in addition to systemics,” he said in the interview.
Asked how he envisions tralokinumab’s role in clinical practice, should the drug receive regulatory approval, Dr. Simpson said that he welcomes the prospect of having an additional treatment option to discuss with patients. Tralokinumab could be considered either as first-line therapy in patients who are failing on topical therapy or for patients who don’t respond adequately to or experience limiting side effects on dupilumab.
“There isn’t any established, published treatment algorithm in atopic dermatitis, probably for good reason, since we don’t have data to tell us you should start here and then move there. Those are long, difficult studies to perform,” Dr. Simpson said.
LEO Pharma has announced that it has applied for marketing approval for tralokinumab to the European Medicines Agency and plans to do so with the Food and Drug Administration by year’s end.
Dr. Simpson reported receiving research grants from and serving as a consultant to LEO Pharma, sponsor of the ECZTRA trials. He has similar financial relationships with close to a dozen other pharmaceutical companies.

At 52 weeks, 51% and 59% of patients in ECZTRA 1 and 2, respectively, who had a clinical response at week 16 maintained an IGA 0/1 response while on tralokinumab every 2 weeks, as did 39% and 45% of those switched to treatment every 4 weeks. Similarly, 60% and 56% of clinical responders at week 16 maintained an EASI-75 response at week 52 with tralokinumab every 2 weeks, as did 49% and 51% of those rerandomized to treatment every 4 weeks.
The safety profile of tralokinumab in the two monotherapy trials was comparable with placebo.
In the ECZTRA studies, tralokinumab achieved significant improvement at week 16 in secondary endpoints including itch, health-related quality of life, and severity and extent of skin lesions.
How does tralokinumab, with its narrower focus targeting a single cytokine, stack up against dupilumab, the dual IL-13/IL-4 inhibitor that’s transformed the treatment of patients with moderate or severe AD?
Dr. Simpson, who was also principal investigator in a pivotal phase 3 trial for dupilumab, emphasized that no firm conclusions can be drawn because there have been no head-to-head comparative trials and the tralokinumab and dupilumab trials had different patient populations, geographic locations, and washout periods. With those caveats, however, he commented that, “just on the surface, numerically, for the monotherapy studies, dupilumab hit some higher targets than tralokinumab in terms of the percentage of patients clear or almost clear.”
In terms of safety, it appears that the risk of conjunctivitis may be lower with tralokinumab than dupilumab, with rates of 7% and 3% through 52 weeks in ECZTRA 1 and 2, respectively, versus 2% with placebo, although again this is “a caveated conclusion,” said Dr. Simpson, professor of dermatology at Oregon Health and Science University, Portland.
Tralokinumab combination therapy in ECZTRA 3
At 16 weeks, 39% of patients treated with tralokinumab plus topical corticosteroids had an IGA of 0/1 and 56% had an EASI-75 response, compared with 26% and 36% of patients on topical corticosteroids plus biweekly placebo injections. More than 90% of patients with a good clinical response at week 16 maintained that response at week 32 while on tralokinumab biweekly plus topical steroids. Among good responders at week 16 who were rerandomized to 300 mg of tralokinumab every 4 weeks plus topical steroids, 78% still had an IGA of 0/1 at week 32, and 91% had an EASI-75, reported Jonathan I. Silverberg, MD, PhD, director of clinical research and contact dermatitis at George Washington University, Washington.
A randomized, placebo-controlled combination therapy study such as this provides information that’s especially useful in clinical practice, Dr. Simpson observed.
“When I’m talking to patients about any biologics or oral therapies, I usually quote the figures from the combination therapy studies because the vast majority of our patients are using topical therapy in addition to systemics,” he said in the interview.
Asked how he envisions tralokinumab’s role in clinical practice, should the drug receive regulatory approval, Dr. Simpson said that he welcomes the prospect of having an additional treatment option to discuss with patients. Tralokinumab could be considered either as first-line therapy in patients who are failing on topical therapy or for patients who don’t respond adequately to or experience limiting side effects on dupilumab.
“There isn’t any established, published treatment algorithm in atopic dermatitis, probably for good reason, since we don’t have data to tell us you should start here and then move there. Those are long, difficult studies to perform,” Dr. Simpson said.
LEO Pharma has announced that it has applied for marketing approval for tralokinumab to the European Medicines Agency and plans to do so with the Food and Drug Administration by year’s end.
Dr. Simpson reported receiving research grants from and serving as a consultant to LEO Pharma, sponsor of the ECZTRA trials. He has similar financial relationships with close to a dozen other pharmaceutical companies.

Psoriasis topical combination maintenance strategy hits mark in phase 3
A proactive long-term strategy of maintenance therapy involving twice-weekly application of combined calcipotriene and betamethasone dipropionate spray foam was safe and effective in patients with moderate plaque psoriasis in the international, randomized PSO-LONG clinical trial, Mark Lebwohl, MD, reported at the virtual annual meeting of the American Academy of Dermatology.
The median time to first relapse – the primary study endpoint – was 56 days in patients randomized to the twice-weekly fixed-dose combination calcipotriene 0.005% and betamethasone dipropionate 0.064% foam (Enstilar), a significantly better outcome than the median 30 days for controls assigned to foam vehicle. Moreover, it took 169 days for 75% of patients on the combination foam to experience their first relapse: three times longer than in controls, added Dr. Lebwohl, principal investigator for PSO-LONG and professor and chair of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York.
The positive results “could have been predicted,” he said in an interview. “But what really distinguishes this study from others is that no one before has ever done a placebo-controlled, double-blind trial with a topical steroid that lasted a year. This is a first, and we’ve shown that if you limit treatment to twice a week you get dramatic improvements in efficacy at no cost in terms of safety.”
The combination spray foam is approved by the Food and Drug Administration as once-daily therapy in psoriasis patients aged 12 years and older, but only for up to 4 weeks because of safety concerns regarding longer use of the potent topical steroid. However, psoriasis is a chronic disease. The PSO-LONG trial was designed to study the impact of a for-now still-investigational long-term maintenance treatment strategy.
The open-label run-in period of the study included 640 adults with plaque psoriasis, 82% of whom had moderate disease at baseline as rated by Physician Global Assessment (PGA). Participants applied the combination foam once daily for 4 weeks. At that point, 80% of them had achieved a PGA rating of clear or almost clear with at least a two-grade improvement from baseline; these 521 responders were then randomized to 52 weeks of double-blind treatment with the combination foam or vehicle foam. Anyone who relapsed went on 4 weeks of once-daily active treatment with the combination foam, then returned to their original treatment arm.
The risk of a first relapse during the course of 1 year was 43% lower with the combination foam than in controls. The relapse rate over the year was 46% lower. Patients in the active treatment arm spent an average of 256.5 days in remission during the year, compared with 222 days in controls.
“That’s more than 1 month more time in remission during the year with active treatment. And remember, if patients flared, they went on daily therapy for a month,” the dermatologist noted.
The rate of treatment-related adverse events was similar in the two groups at 2.8 events per 100 patient-years in the combination foam arm and 4.5 per 100 patient-years in controls. The twice-weekly active treatment group had no increase in stretch marks, telangiectasias, skin atrophy, serum calcium, or abnormalities of the hypothalamic-pituitary-adrenal axis.
Although the combination foam is approved for daily use for a maximum of 1 month in adolescents and adults, PSO-LONG was restricted to adults.
“I think that what will happen in the marketplace is that the data obtained from this adult study will likely be applied to younger patients,” Dr. Lebwohl predicted.
He reported receiving an institutional research grant to conduct the trial from LEO Pharma, the study sponsor, as well as serving as a consultant to and researcher for the company.

Study spotlights the skin microbiome’s evolving nature
, while the skin microbiome of the mothers of the children whose microbiome was analyzed remained relatively constant over the same time period.
The findings come from what is believed to be the longest longitudinal study specific to the skin microbiome of infants and mothers.
“Even at 10 years, the skin microbiome does not look like an adult skin microbiome, based on composition of the ecosystem,” lead author Kimberly A. Capone, PhD, said in an interview during the virtual annual meeting of the American Academy of Dermatology. “The diversity of the microbiome in children’s skin is distinct to that of an adult’s skin. We all have the same bacteria present, but in children it is distributed differently because the bacteria set themselves up based on the nutrients and topography that they find on the skin. Since infant skin is unique to infants, so too is their microbiome when we compare it to adults. It’s been fascinating to observe these children grow and mature, and follow the skin microbiome along this same period.”
During five time points over a period of 10 years, Dr. Capone and her colleagues at the Skillman, N.J.–based Johnson & Johnson Consumer Experience Center, a research and development site, used 16s rRNA gene sequencing to evaluate the skin microbiome on the forearms and foreheads of 30 mothers and their 31 children. The study participants had Fitzpatrick skin types I-IV and the mean age of mothers was 37 years. “We used 16s rRNA gene sequencing for microbiome analysis at the beginning, as that was what was available 10 years ago,” said Dr. Capone, head of the microbiome platform for Johnson & Johnson Consumer Health. “Since then, we continue to use 16s for continuity, but also collected additional swabs for deeper analysis later.”
She and her colleagues often draw samples from the forearm in baby skin clinical studies, “as the arm is a good site to collect relevant data on the body overall,” she explained. “We chose the forearm and forehead specifically here so we can make same body site comparisons to adult sample data which we took from the mothers on the same areas of their body.” Time point 1 was 3 months to 1 year, time point 2 was 2-3 years, time point 3 was 5-6 years, time point 4 was 7-8 years, and time point 5 was 9-10 years.
The researchers found that the skin of infants during the first few weeks of life was similar at age 3 and 4 years. “From that second time point on, we see significant increases in richness and diversity, richness being presence or absence of various bacterial species, and diversity being the relative abundance of those species,” Dr. Capone said. “What you’re basically seeing is that there are new organisms, i.e., richness, coming into the microbiome. We start to detect new ones. Over time, the ecosystem is expanding. It’s evolving because it’s not yet set up.” The evolving skin microbiome on children was dominated by Streptococcus and Staphylococcus. In addition, children had higher levels of Streptococcus, Moraxella, Granulicatella, Gemella and Veillonella, compared with their adult mothers. Adult skin was colonized predominantly by Propionibacterium/Cutibacterium and Staphylococcus.
“The skin microbiome also increased in diversity over time on the forearm, but not face, of the mothers,” Dr. Capone said. “Previous studies have shown how stable the adult skin microbiome is, so it’s intriguing to see the changes that we saw on the mothers in this study.”
The increase in skin microbiome diversity observed in the children is likely due to a variety of factors, she continued, including inherent growth and development, dietary changes, as well as exposure to various environments and other people. “The fact remains that diversity is increasing over time, as the ecosystem evolves,” she said. “Eventually, the skin microbiome will become ‘adultlike’ in puberty, when lipid production increases. This drives increases in Cutibacterium acnes, particularly on the face.”
She acknowledged certain limitations of the study, including its relatively small size and the fact that some of the original subjects did not return for microbiome analysis at later time points. “We need larger cohort studies, additional deeper sequence data, metabolomics and transcriptomics to better understand the function of the skin microbiome over these various ages,” she said.

Results from two phase 3 trials of bimekizumab unveiled
Results from two late-breaking
“The rapid and lasting skin clearance observed in the majority of patients in both clinical studies demonstrate bimekizumab’s strong potential to deliver across three key areas: speed, depth and durability,” Kristian Reich, MD, said in an interview during the virtual annual meeting of the American Academy of Dermatology.
Bimekizumab selectively inhibits IL-17A and IL-17F, two key cytokines that drive inflammation and tissue damage across multiple diseases. In BE VIVID, Dr. Reich, of the Center for Translational Research in Inflammatory Skin Diseases at the University Medical Center Hamburg-Eppendorf (Germany), and colleagues randomized 567 patients with moderate to severe psoriasis to bimekizumab 320 mg every 4 weeks (Q4W), ustekinumab (45/90 mg weight-based dosing at baseline and week 4, then every 12 weeks), or placebo (Q4W through week 16 then bimekizumab 320 mg Q4W). Coprimary endpoints were a Psoriasis Area and Severity Index (PASI) of at least 90 and an Investigator Global Assessment (IGA) response of 0 or 1. Secondary/other outcomes included PASI 100 at week 16; PASI 90, IGA 0/1, and PASI 100 at week 52; and safety. (Ustekinumab is an IL-12 and IL-23 antagonist.)
The mean age of patients was 46 years and 72% were male. The researchers found that the proportion of patients who achieved PASI 90 and an IGA of 0/1 was higher in the bimekizumab arm at week 16 (85.0% and 84.1%, respectively), compared with those in the ustekinumab arm (49.7% and 53.4%) and those on placebo (4.8% and 4.8%; P < .001 for all associations). In addition, 58.6% of patients in the bimekizumab arm achieved PASI 100, compared with 20.9% of those in the ustekinumab arm and none of those on placebo.
At week 52, patients in the bimekizumab arm achieved PASI 90, IGA 0/1, and PASI 100 response rates of 81.6%, 77.9%, and 64.2%, respectively, compared with 55.8%, 60.7%, and 38.0% of those in the ustekinumab arm. Over 52 weeks, incidence of serious treatment-emergent adverse events was 6.1% with bimekizumab arm, compared with 7.4% in the ustekinumab arm. Four deaths occurred (two in the bimekizumab arm, and one each in the ustekinumab and placebo arms), all considered unrelated to treatment. The most common reported adverse events in the bimekizumab arm through week 52 were nasopharyngitis (21.8%), oral candidiasis (15.2%), and upper respiratory tract infections (9.1%).
“The rapid and lasting skin clearance observed in the majority of patients treated with bimekizumab provide support for inhibiting IL-17F, in addition to IL-17A, to inhibit the IL-17 pathway,” Dr. Reich said. “This can make a meaningful difference for people living with psoriasis.” He added that the results of the head-to-head study of bimekizumab with secukinumab (an IL-17A antagonist) are expected later this year. “It will be very interesting to see if the marked differences in treatment effect seen in the BE VIVID study remain when comparing to an IL-17.”
In BE READY, a pivotal phase 3, randomized, withdrawal study, investigators led by Kenneth Gordon, MD, randomized 435 patients with moderate to severe psoriasis 4:1 to receive 320 mg Q4W or placebo, and followed them for 16 weeks. In a second part of the study, patients who had achieved at least a PASI 90 response at week 16 were rerandomized to receive continuous bimekizumab at two different dosing regimens: 320 mg Q4W or 320 mg every 8 weeks (Q8W), or to be withdrawn from treatment (placebo Q4W), and followed through week 56. Relapse was defined as a PASI score of less than 75 from week 20.
The mean age of patients was 44 years and 72% were male. At week 16, the proportion of patients who achieved a PASI 90 and an IGA of 0/1 was greatest in the bimekizumab arm (90.8% and 92.6%, respectively), compared with those on placebo. In addition, 68.2% of patients in the bimekizumab arm achieved PASI 100 at week 16, compared with only 1.2% of those on placebo (P < .001 for all associations). In the second part of the study, the researchers found that 86.8% of patients who received continuous bimekizumab 320 mg Q4W maintained PASI 90 at week 56, compared with 91% who were switched to bimekizumab 320 mg Q8W, and 16.2% of patients who were withdrawn from the trial.
“The speed of response and the number of patients who achieved clearance are extremely high, especially in a phase 3 trial,” Dr. Gordon, professor and Thomas R. Russell Family Chair of Dermatology at the Medical College of Wisconsin, Milwaukee, said in an interview. “However, the most surprising aspect may be the impressive maintenance of response in patients, even those who were treated with every-8-week dosing in the maintenance phase. While it is possible that there are some patients who may benefit from more frequent dosing in the long term, the possibility of every-8-week dosing would be a tremendous benefit for patients.”
As in the BE VIVID trial, the most frequently reported adverse events with bimekizumab between week 16 and week 56 in BE READY were nasopharyngitis (10.4% in the Q4W arm vs. 23% in the Q8W arm), oral candidiasis (11.3% Q4W vs. 9% Q8W), and upper respiratory tract infections (11.3% Q4W vs. 8% Q8W). The incidence of serious treatment-emergent adverse events with bimekizumab was 4.7% in the Q4W arm and 3% in the Q8W arm versus 3.8% in the placebo arm at week 56.
“The results from BE READY demonstrate that bimekizumab has the potential to deliver rapid and lasting skin improvement for psoriasis patients,” Dr. Gordon said. “The findings also support the hypothesis that inhibiting IL-17F, in addition to IL-17A, may be more effective in suppressing inflammation in suppressing inflammation in psoriasis than IL-17A inhibition alone.”

Results from two late-breaking
“The rapid and lasting skin clearance observed in the majority of patients in both clinical studies demonstrate bimekizumab’s strong potential to deliver across three key areas: speed, depth and durability,” Kristian Reich, MD, said in an interview during the virtual annual meeting of the American Academy of Dermatology.
Bimekizumab selectively inhibits IL-17A and IL-17F, two key cytokines that drive inflammation and tissue damage across multiple diseases. In BE VIVID, Dr. Reich, of the Center for Translational Research in Inflammatory Skin Diseases at the University Medical Center Hamburg-Eppendorf (Germany), and colleagues randomized 567 patients with moderate to severe psoriasis to bimekizumab 320 mg every 4 weeks (Q4W), ustekinumab (45/90 mg weight-based dosing at baseline and week 4, then every 12 weeks), or placebo (Q4W through week 16 then bimekizumab 320 mg Q4W). Coprimary endpoints were a Psoriasis Area and Severity Index (PASI) of at least 90 and an Investigator Global Assessment (IGA) response of 0 or 1. Secondary/other outcomes included PASI 100 at week 16; PASI 90, IGA 0/1, and PASI 100 at week 52; and safety. (Ustekinumab is an IL-12 and IL-23 antagonist.)
The mean age of patients was 46 years and 72% were male. The researchers found that the proportion of patients who achieved PASI 90 and an IGA of 0/1 was higher in the bimekizumab arm at week 16 (85.0% and 84.1%, respectively), compared with those in the ustekinumab arm (49.7% and 53.4%) and those on placebo (4.8% and 4.8%; P < .001 for all associations). In addition, 58.6% of patients in the bimekizumab arm achieved PASI 100, compared with 20.9% of those in the ustekinumab arm and none of those on placebo.
At week 52, patients in the bimekizumab arm achieved PASI 90, IGA 0/1, and PASI 100 response rates of 81.6%, 77.9%, and 64.2%, respectively, compared with 55.8%, 60.7%, and 38.0% of those in the ustekinumab arm. Over 52 weeks, incidence of serious treatment-emergent adverse events was 6.1% with bimekizumab arm, compared with 7.4% in the ustekinumab arm. Four deaths occurred (two in the bimekizumab arm, and one each in the ustekinumab and placebo arms), all considered unrelated to treatment. The most common reported adverse events in the bimekizumab arm through week 52 were nasopharyngitis (21.8%), oral candidiasis (15.2%), and upper respiratory tract infections (9.1%).
“The rapid and lasting skin clearance observed in the majority of patients treated with bimekizumab provide support for inhibiting IL-17F, in addition to IL-17A, to inhibit the IL-17 pathway,” Dr. Reich said. “This can make a meaningful difference for people living with psoriasis.” He added that the results of the head-to-head study of bimekizumab with secukinumab (an IL-17A antagonist) are expected later this year. “It will be very interesting to see if the marked differences in treatment effect seen in the BE VIVID study remain when comparing to an IL-17.”
In BE READY, a pivotal phase 3, randomized, withdrawal study, investigators led by Kenneth Gordon, MD, randomized 435 patients with moderate to severe psoriasis 4:1 to receive 320 mg Q4W or placebo, and followed them for 16 weeks. In a second part of the study, patients who had achieved at least a PASI 90 response at week 16 were rerandomized to receive continuous bimekizumab at two different dosing regimens: 320 mg Q4W or 320 mg every 8 weeks (Q8W), or to be withdrawn from treatment (placebo Q4W), and followed through week 56. Relapse was defined as a PASI score of less than 75 from week 20.
The mean age of patients was 44 years and 72% were male. At week 16, the proportion of patients who achieved a PASI 90 and an IGA of 0/1 was greatest in the bimekizumab arm (90.8% and 92.6%, respectively), compared with those on placebo. In addition, 68.2% of patients in the bimekizumab arm achieved PASI 100 at week 16, compared with only 1.2% of those on placebo (P < .001 for all associations). In the second part of the study, the researchers found that 86.8% of patients who received continuous bimekizumab 320 mg Q4W maintained PASI 90 at week 56, compared with 91% who were switched to bimekizumab 320 mg Q8W, and 16.2% of patients who were withdrawn from the trial.
