Both drugs are well tolerated
The drugs were similarly well tolerated. Serious adverse events were uncommon in either arm. The rate of study dropouts due to an adverse event potentially related to treatment assignment was 3% in each group.
Nausea (19% vs. 2%), acne (13.5% vs. 2%), and headache (13% vs. 7.5%) were all more common in patients randomly assigned to abrocitinib. Conjunctivitis was more common in the group randomly assigned to dupilumab (10% vs. 2%).
The two deaths that occurred during this study were in the abrocitinib arm, but one was the result of COVID-19 infection and the other was a cardiovascular event in a patient with risk factors. Neither was considered to be treatment-related.
Abrocitinib’s relative selectivity for the JAK1 inhibitor is a potential differentiator from other currently available JAK inhibitors, although direct comparisons of these therapies for clinical activity in AD as well as most other diseases remains limited.
The relatively rapid relief of pruritus with the JAK inhibitor relative to the monoclonal antibody in the JADE DARE trial is likely to be perceived as clinically significant by patients with AD, according to Sonja Ständer, MD, professor of dermatology and neurodermatology at the University Hospital Münster, Germany.
“One of the highest needs of patients with atopic dermatitis is a rapid and profound relief of itch,” Dr. Ständer, who wrote a review article on AD earlier this year, said in an interview.
Although several current therapies are effective against pruritus, Dr. Ständer believes that the higher proportion of patients achieving itch control at 2 weeks on abrocitinib “will attract the attention of affected patients.”
However, she added that patients need to take both benefits and risks into account, indicating that clinical utility cannot be judged on a single outcome. In selecting one drug over the others, she advised “a balanced use of therapies.”
Abrocitinib was first approved in the United Kingdom in early September, followed by Japan last Thursday, for the treatment of moderate to severe AD in patients ages 12 and older. It is under review elsewhere, including in the United States and the European Union for AD.
In September, the FDA approved the first JAK inhibitor for treating AD – a topical JAK inhibitor, ruxolitinib.
Dr. Reich reports financial relationships with 20 pharmaceutical companies, including Pfizer, which provided funding for the JADE DARE trial. Dr. Ständer reports financial relationships with Beiersdorf AG, Galderma, Kliniska, Lilly, Pfizer, and Sanofi.
