, and with a safety profile essentially indistinguishable from vehicle cream in a phase 2b randomized trial, Megan N. Landis, MD, reported at the virtual annual congress of the European Academy of Dermatology and Venereology.
The study included 240 adolescents and adults with mild to moderate AD at 70 sites in the United States and nine other countries. Patients’ mean baseline Eczema Area and Severity Index (EASI) score was 7.3, with 9.2% of their body surface area being involved. Participants were equally split between mild and moderate disease. They were randomized to 6 weeks of double-blind treatment in one of eight study arms: once-daily topical brepocitinib at a concentration of 0.1%, 0.3%, 1%, or 3%; twice-daily brepocitinib at 1% or 3%; or once- or twice-daily vehicle cream.
The primary endpoint was change in EASI score from baseline to week 6. Brepocitinib 1% and 3% once daily and 1% twice daily outperformed vehicle, with EASI score reductions of 70.1%, 67.9%, and 75%, respectively, compared with a 44.4% decrease among those in the once-daily vehicle control group and a 47.6% reduction among those in the twice-daily vehicle control group, according to Dr. Landis, a dermatologist at the University of Louisville (Ky).
The key secondary efficacy endpoint was the proportion of patients achieving an Investigator’s Global Assessment (IGA) score of 0 or 1 – clear or almost clear skin – plus at least a 2-point reduction at week 6. This occurred in a dose-dependent fashion in 27.8%-44.4% of patients on once-daily brepocitinib, all significantly better results than the 10.8% rate in once-daily controls. Patients on the TYK2/JAK1 inhibitor at 0.3% twice daily had a 33.3% IGA response rate, versus 13.9% with twice-daily vehicle, also a significant difference.
A 90% reduction in EASI score at week 6, or EASI 90 response, occurred in a dose-dependent fashion in 27.8%-41.7% of patients on 0.3%, 1%, and 3% of patients on once-daily brepocitinib, all significantly better than the 10.8% rate with once-daily vehicle, and in 27% of patients on brepocitinib 1% twice daily, versus 8.3% with twice-daily vehicle.
Improvement in itch was another secondary endpoint. A clinically meaningful week-6 improvement of at least 4 points on the Peak Pruritus Numerical Rating Scale was documented in 45.2% of patients on 1% brepocitinib once daily, 50% on 3% once daily, and 40.7% on 1% brepocitinib twice daily, all significantly better than the roughly 17% itch response rate in controls.
Treatment-emergent adverse events were about one-third more frequent in controls than in brepocitinib-treated patients. These events were overwhelmingly mild and were similar in nature in the two groups. There was no dose-dependent increase in treatment-emergent adverse events in the brepocitinib patients. Moreover, no serious treatment-emergent adverse events occurred during the study, nor were there any cases of herpes zoster or malignancies, and no changes in laboratory parameters or ECG findings.
Pfizer sponsored the phase 2b AD trial of the topical TYK2/JAK1 inhibitor, which is also in phase 2 studies for psoriatic arthritis, psoriasis, lupus, and alopecia areata.
Dr. Landis reported serving as a paid investigator for Pfizer and numerous other pharmaceutical companies.
