Safety of secukinumab in the treatment of psoriasis.

INTRODUCTION: Secukinumab is a human monoclonal antibody that selectively targets and neutralizes interleukin (IL)-17A, a cytokine that is normally involved in mucocutaneous defense against extracellular organisms and is abnormally expressed in psoriasis. In 2015, secukinumab was the first IL-17A inhibitor approved for the treatment of moderate-to-severe psoriasis. AREAS COVERED: This review evaluates the safety profile of secukinumab for the treatment of moderate-to-severe psoriasis and its role in the clinical landscape. A literature search was performed for articles published through February 2016; additional data from a pooled safety analysis of 10 Phase II and III secukinumab studies were reviewed. EXPERT OPINION: Collectively, these studies show that secukinumab demonstrates a highly favorable safety profile, especially compared with commonly used psoriasis treatments such as methotrexate and TNF-α blockers. More specifically, secukinumab carries no increased risks for end-organ toxicities, serious infection, multiple sclerosis, reactivation of latent tuberculosis or hepatitis B, leukemia/lymphoma, and nonmelanoma skin cancer. Mucocutaneous candidiasis is a common side effect and occurs at a rate of 3.55/100 subject-years with secukinumab 300 mg, yet these infections usually do not interfere with maintenance of secukinumab therapy. The combination of proven efficacy and safety make secukinumab an excellent new treatment choice for individuals with moderate-to-severe psoriasis.
