Study to Evaluate the Efficacy of Etanercept Treatment in Adults Who Failed Therapy With Apremilast

Open Label Study to Evaluate the Efficacy of Etanercept Treatment in Subjects With Moderate to Severe Plaque Psoriasis Who Have Failed Therapy With Apremilast

To evaluate the efficacy of etanercept in adults with moderate to severe plaque psoriasis who have failed therapy with apremilast (Otezla).

This is a multicenter, open-label, single-arm, phase 4, estimation study in adults with plaque psoriasis (PsO) who have failed apremilast. The study will consist of a screening period of up to 45 days, a 24-week treatment period with study visits every 4 weeks, and a 30-day follow-up period for safety. Etanercept dosing will follow the recommended label dosing for adults with plaque psoriasis.

• Subject is currently receiving treatment with apremilast for moderate to severe plaque PsO or subject has discontinued treatment with apremilast for PsO within the past 3 months prior to screening
