Both are IL-17 inhibitors. Here is how Cosentyx and Bimzelx compare on class, mechanism, dosing, approval and supply.
At a glance
Key differences
- Same class. Both Cosentyx and Bimzelx are IL-17 inhibitors, so they work through the same broad mechanism. Differences between them tend to be about dosing, route, how selective they are, and side effects rather than what they target.
- How they are taken. Cosentyx is given by the intravenous, subcutaneous route; Bimzelx by the subcutaneous route.
- Time on the market. Cosentyx was first approved by the FDA in 2015, Bimzelx in 2023. That gives Cosentyx roughly 8 more years of real-world use and long-term safety data.
- Who markets them. Cosentyx is marketed by Novartis; Bimzelx by UCB.

How each one works
12.1 Mechanism of Action Secukinumab is a human IgG1 monoclonal antibody that selectively binds to the interleukin-17A (IL-17A) cytokine and inhibits its interaction with the IL-17 receptor. IL-17A is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Secukinumab inhibits the release of proinflammatory cytokines and chemokines.
12.1 Mechanism of Action Bimekizumab-bkzx is a humanized immunoglobulin IgG1/ κ monoclonal antibody with two identical antigen binding regions that selectively bind to human interleukin 17A (IL-17A), interleukin 17F (IL-17F), and interleukin 17-AF cytokines, and inhibits their interaction with the IL-17 receptor complex. IL-17A and IL-17F are naturally occurring cytokines that are involved in normal inflammatory and immune responses. Bimekizumab-bkzx inhibits the release of proinflammatory cytokines and chemokines.

Which medicine is right for a given person depends on their diagnosis, other conditions, other medicines, kidney and liver function, pregnancy, and cost or reimbursement — none of which this page knows. Two drugs in the same class are not automatically interchangeable. Never start, stop or switch a prescription medicine on the basis of a web page; that decision belongs to you and your clinician or pharmacist.
