'While new options are increasingly available for the treatment of atopic dermatitis, individual patients have different responses to therapies and therefore require different solutions,' said Professor
In this Phase 2a double-blind, placebo-controlled study, participants were randomized to either intravenous amlitelimab-low dose (LD) (n=29), intravenous amlitelimab-high dose (HD) (n=30) or placebo (n=29) and were treated every four weeks over a 12-week period. Eligible patients included adults with moderate-to-severe atopic dermatitis whose disease is inadequately controlled with topical therapies such as corticosteroids, or where such therapies were not advisable.
Co-primary endpoints included percent change in
At week 16, the data demonstrated that when dosed every four weeks:
Patients treated with amlitelimab-LD showed 80% improvement in average
The onset of response versus placebo was seen as early as Week 2 for both amlitelimab groups. No meaningful difference in responses was seen for the amlitelimab-LD and amlitelimab-HD groups.
The overall rate of TEAEs was 35% for amlitelimab-LD, 17% for amlitelimab-HD and 31% for placebo. One serious adverse event was reported in the amlitelimab-LD group (infected atheroma) deemed related by the investigator at week 16; the event was resolved, and the patient was able to complete the study. No hypersensitivity reactions were reported.
Also, at 16 weeks, key secondary endpoint data included:
44% of patients treated with amlitelimab-LD and 37% of patients treated with amlitelimab-HD achieved a score of 0 (clear) or 1 (almost clear) on the validated Investigator's Global Assessment (vIGA) scale compared with 8% with placebo (p
