Actemra vs Kevzara
Both are IL-6 inhibitors. Here is how Actemra and Kevzara compare on class, mechanism, dosing, approval and supply.
At a glance
Key differences
- Same class. Both Actemra and Kevzara are IL-6 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. Actemra is given by the intravenous, subcutaneous route; Kevzara by the subcutaneous route.
- Time on the market. Actemra was first approved by the FDA in 2010, Kevzara in 2017. That gives Actemra roughly 7 more years of real-world use and long-term safety data.
- Who markets them. Actemra is marketed by Genentech (Roche); Kevzara by Sanofi.
- Same drug, more than one brand. Tocilizumab is sold as Actemra / RoActemra — the same active ingredient marketed under different brand names, typically for different approved uses or doses.

How each one works
12.1 Mechanism of Action Tocilizumab binds to both soluble and membrane-bound IL-6 receptors (sIL-6R and mIL-6R), and has been shown to inhibit IL-6-mediated signaling through these receptors. IL-6 is a pleiotropic pro-inflammatory cytokine produced by a variety of cell types including T- and B-cells, lymphocytes, monocytes and fibroblasts. IL-6 has been shown to be involved in diverse physiological processes such as T-cell activation, induction of immunoglobulin secretion, initiation of hepatic acute phase protein synthesis, and stimulation of hematopoietic precursor cell proliferation and differentiation. IL-6 is also produced by synovial and endothelial cells leading to local production …

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.
