Delivery method

Secukinumab is approved for the treatment of moderate to severe plaque psoriasis in adults and children, psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, and moderate to severe hidradenitis suppurativa.

Secukinumab is a monoclonal antibody that selectively binds to and neutralizes the IL-17A cytokine, preventing it from interacting with its receptor and interrupting the inflammatory cascade that contributes to autoimmune disease.

As an immunosuppressant, secukinumab may increase the risk of infections, including serious infections. It is administered by subcutaneous injection and requires appropriate monitoring. Patients should be screened for tuberculosis before starting treatment.
