Introduction: We evaluated the efficacy of brodalumab in patients with nail or scalp psoriasis in three phase 3 studies (AMAGINE-1/-2/-3). Methods: In AMAGINE-1, scalp clearance, measured by the psoriasis scalp severity index (PSSI), was reported for patients who received brodalumab 210 mg every 2 weeks (Q2W) or placebo through 12 weeks. In AMAGINE-2/-3, nail clearance, measured by the nail psoriasis severity index (NAPSI), was reported for patients receiving either brodalumab 210 mg Q2W or ustekinumab continuously through 52 weeks. Results: At week 12, significantly more patients receiving brodalumab achieved 75% and 100% improvement rates from baseline PSSI and had lower mean PSSI across 12 weeks compared with placebo, with significant improvement in PSSI evident with brodalumab 210 mg Q2W vs placebo by week 2. Across 52 weeks, patients receiving brodalumab achieved significantly greater complete clearance of nail psoriasis (NAPSI 0), lower mean NAPSI, and higher mean percent improvement rates from baseline NAPSI than patients receiving ustekinumab. At week 52, 63.8% of patients receiving brodalumab achieved NAPSI 0 vs 39.1% of patients receiving ustekinumab. Conclusions: Brodalumab was associated with clearance of scalp psoriasis through 12 weeks and improvements in nail psoriasis, including complete nail clearance, through 52 weeks.
