Avsola is approved for the treatment of moderate to severe plaque psoriasis in adults who are candidates for phototherapy or systemic therapy, active psoriatic arthritis, moderate to severe Crohn's disease, and moderate to severe ulcerative colitis.
Avsola is a monoclonal antibody that binds to and blocks the activity of interleukin-12 (IL-12) and interleukin-23 (IL-23), which are proteins that play a key role in inflammation and the abnormal immune response seen in these autoimmune conditions.
Avsola is administered by subcutaneous injection or intravenous infusion under the supervision of a healthcare provider. Patients should be monitored for infections, as immunosuppressive medications may increase the risk of serious infections. Live vaccines should be avoided during treatment. Common side effects may include upper respiratory infections, headache, and fatigue. A patient assistance program may be available for eligible patients.
