Background |
Previous clinical trials have not evaluated improvement in nail psoriasis as a primary end point.
Objective |
This phase 3 trial evaluated the safety and efficacy of adalimumab in patients with moderate-to-severe fingernail psoriasis and moderate-to-severe plaque psoriasis.
Methods |
Patients were randomized 1:1 to 40 mg adalimumab every other week or placebo. The primary efficacy end point was at least 75% improvement in total-fingernail modified Nail Psoriasis Severity Index (NAPSI75) response rate at week 26. Ranked secondary end point scores evaluated at week 26 were total-fingernail NAPSI and modified NAPSI, nail pain, Nail Psoriasis Physical Functioning Severity, Brigham Scalp Nail Inverse Palmo-Plantar Psoriasis Index, and Physician's Global Assessment (fingernail psoriasis).
Results |
Of the 217 randomized patients (108 received placebo and 109 received adalimumab), 188 (86.6%) completed 26 weeks of treatment (period A) or escaped early to the open-label period. The study met the primary end point (response rate of 3.4% with placebo vs 46.6% with adalimumab [P < .001]) and all ranked secondary end points. The serious adverse event rates (placebo vs adalimumab) in period A were 4.6% versus 7.3%; the serious infections rates were 1.9% versus 3.7%.
Limitations |
Patients with less than 5% BSA involvement were not eligible for enrollment.
Conclusions |
After 26 weeks of adalimumab treatment, significant improvements were seen in the primary and all ranked secondary end points and in signs and symptoms of moderate-to-severe nail psoriasis versus with placebo and no new safety risks were identified.
