Brodalumab: A Review in Moderate to Severe Plaque Psoriasis.

Brodalumab (Kyntheum® ) is a human anti-interleukin-17 receptor A (IL-17RA) monoclonal antibody available for use in patients with moderate to severe plaque psoriasis. In the phase III AMAGINE trials in this patient population, 12 weeks of induction therapy with subcutaneous brodalumab was superior to placebo in terms of the proportion of patients with ≥ 75% improvement in the Psoriasis Area and Severity Index score (PASI 75) and the proportion of patients with a static Physician Global Assessment score of 0 or 1. Brodalumab was also superior to ustekinumab for PASI 100 (i.e. complete skin clearance) at week 12. Health-related quality of life (HR-QOL) outcomes improved to a significantly greater extent with brodalumab than with placebo. Moreover, brodalumab was more effective than placebo in patients with difficult-to-treat nail or scalp psoriasis. Brodalumab was generally well tolerated, with low rates of immunogenicity. Efficacy was sustained and brodalumab remained well tolerated during up to 52 weeks of maintenance therapy. Thus, subcutaneous brodalumab is a useful addition to the treatment options currently available for patients with moderate to severe plaque psoriasis.
