Brief Summary:

This Phase 3 multicenter, randomized, placebo-controlled, double-blind study is designed to evaluate the efficacy and safety of apremilast in subjects with moderate to severe genital psoriasis (modified sPGA-G ≥3, moderate or severe).

Approximately 286 subjects with moderate to severe genital psoriasis will be randomized 1:1 to receive either apremilast 30 mg BID or placebo for the first 16 weeks.

Condition or disease Intervention/treatment Phase
Psoriasis Drug: Apremilast Other: Placebo Phase 3

Expanded Access : An investigational treatment associated with this study is no longer available outside the clinical trial.   More info ...

Detailed Description:

The study will consist of four phases:

  • Screening Phase - up to 35 days
  • Double-blind Placebo-controlled Phase - Weeks 0 to 16

    - Subjects will be randomly assigned to either apremilast 30 mg tablets orally BID or placebo tablets (identical in appearance to apremilast 30 mg tablets) orally BID.

  • Apremilast Extension Phase - Weeks 16 to 32

    - All subjects will be switched to (or continue with) apremilast 30 mg BID. All subjects will maintain this dosing through Week 32.

  • Observational Follow-up Phase - 4 weeks - Four-week Post-Treatment Observational Follow-up Phase for all subjects who complete the study or discontinue the study early.
