Wezlana™
Understanding Wezlana®
Wezlana® (ustekinumab-auub) is a biosimilar to Stelara® (ustekinumab), developed by Amgen. It is a monoclonal antibody that targets interleukin-12 (IL-12) and interleukin-23 (IL-23), cytokines involved in inflammatory and immune responses. By inhibiting these cytokines, Wezlana® helps reduce inflammation associated with certain autoimmune conditions.
How Wezlana® Works:
- Binds to the p40 protein subunit shared by IL-12 and IL-23, preventing their interaction with cell surface receptors.
- Inhibits the activation of T-helper cells, reducing the release of pro-inflammatory cytokines.
- Decreases inflammation and immune-mediated tissue damage in affected conditions.
FDA Approval:
- October 31, 2023 – Approved as an interchangeable biosimilar to Stelara® for:
- Moderate to severe plaque psoriasis in adults and pediatric patients aged 6 years and older.
- Active psoriatic arthritis in adults and pediatric patients aged 6 years and older.
- Moderately to severely active Crohn’s disease in adults.
- Moderately to severely active ulcerative colitis in adults
