Drug safety evaluation of apremilast for treating psoriatic arthritis.

INTRODUCTION: Apremilast is an orally available small molecule that targets PDE4. PDE4 modulates intracellular signaling and thereby can impact various proinflammatory and anti-inflammatory mediators. Apremilast has been approved by the USA FDA for the treatment of active psoriatic arthritis (PsA) and moderate-to-severe psoriasis (PsO). Although there are several therapies approved and used for the treatment of PsA, there is still an unmet need for additional effective and well-tolerated therapeutic options. In PsA clinical trials, apremilast has been shown to be efficacious and to have an acceptable safety profile.

AREAS COVERED: This review article covers the mechanism of action of apremilast, its efficacy in clinical trials and a detailed focus on its safety profile, mainly from Phase III clinical trials.

EXPERT OPINION: Based on the available literature, apremilast has proven to be an efficacious therapy for PsA and PsO. It may offer some advantage as compared to other therapeutic options given its favorable safety profile, including a lack of need for routine laboratory monitoring.
