Is Cosentyx approved for adults with moderate to severe plaque psoriasis?

high confidence  ·  Last reviewed May 17, 2026

Cosentyx (secukinumab) is a biologic medication that targets interleukin-17A, a protein involved in psoriasis inflammation. The FDA has approved Cosentyx for adults with moderate to severe plaque psoriasis who are candidates for systemic therapy (medication taken internally) or phototherapy (light treatment). This approval covers both initial treatment and switching from other therapies.

What the research says

The FDA label for Cosentyx specifically states it is indicated for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy 1. This approval is based on clinical trials showing that Cosentyx is more effective than placebo and other biologics like etanercept and ustekinumab at clearing psoriasis and improving quality of life 7. Long-term safety data from over 12,000 patients across multiple studies show a favorable safety profile for up to 5 years, with low rates of serious infections, tuberculosis, and malignancies 6. In a real-world study comparing biologics for nail psoriasis, anti-IL-17A treatments including Cosentyx showed greater improvement in nail symptoms compared to other biologic classes 8. A network meta-analysis in pediatric patients also found that secukinumab ranked among the best for achieving high levels of skin clearance 4.
