Efficacy of Secukinumab for Moderate-to-Severe Head and Neck Psoriasis Over 52 Weeks: Pooled Analysis of Four Phase 3 Studies

Psoriasis affecting the head and neck can be difficult to treat, and the presence of extensive and highly visible lesions may result in substantial psychosocial burdens. Secukinumab, a monoclonal antibody that selectively targets interleukin-17A, provides rapid and sustained clearance of moderate-to-severe psoriasis. The objective of this study was to evaluate the efficacy of secukinumab on moderate-to-severe psoriasis affecting the head and neck. The safety and overall efficacy of secukinumab in patients with moderate-to-severe psoriasis will be described.

Methods: Data were pooled from four phase 3 studies. To be included in the head and neck analysis, patients were required to have Baseline head and neck Psoriasis Severity Area Index (PASI) scores ≥12 and psoriasis covering ≥10% of the head and neck. Secukinumab (300 or 150 mg) was administered at Baseline, Weeks 1, 2 and 3, and then every 4 weeks from Week 4 to 48.

Results: Secukinumab demonstrated high efficacy on the head and neck and the whole body. At Week 52, head and neck PASI 90/100 subscore responses were achieved by 76.0%/68.7% of patients receiving secukinumab 300 mg, respectively, and by 61.4%/53.1% of patients receiving secukinumab 150 mg, respectively. At Week 52, whole body composite PASI 90/100 responses were achieved by 68.1%/40.8% of patients receiving secukinumab 300 mg, respectively, and by 47.6%/24.3% of patients receiving secukinumab 150 mg, respectively. Secukinumab also improved Dermatology Life Quality Index scores.

Conclusion: Secukinumab provided robust and sustained efficacy for head and neck, and whole body psoriasis, over 52 weeks, with a favorable safety profile.
