Introduction
Psoriasis is a chronic skin disease in which interleukin-17A (IL-17A) has been found to play an important role. Commercially available anti-IL-17 drugs include brodalumab, ixekizumab (IXE), and secukinumab (SEC).
Aim
To compare the safety and efficacy of IXE and SEC in patients with moderate-to-severe plaque psoriasis.
Material and methods
The patients were randomized to the IXE or SEC group. Effectiveness was estimated by Physician’s Global Assessment (PGA), Psoriasis Area and Severity Index (PASI), and Dermatology Life Quality Index (DLQI). Safety was assessed by documentation of adverse effects (AEs), routine laboratory values, and injection-site and allergic reactions.
Results
There were 155 patients in the IXE group and 158 in the SEC group. At week 12, PASI 75 was 76.77% (IXE) vs. 67.09% (SEC); PASI 90 42.58% (IXE) vs. 32.28% (SEC); PGA score of 0 or 1 at week 40 (79.52% vs. 74.4%) and at week 52 (61.83% vs. 58.12%) (p < 0.001). Also, DLQI score improvement was more pronounced in the IXE group. The rates and types of AEs were similar in both groups.
Conclusions
Although both groups demonstrated a robust clinical response, a significant improvement in patient quality of life, and a satisfactory safety profile, the IXE group scored a notch higher.
