Humira vs Actemra
Blocking TNF against blocking IL-6 in rheumatoid arthritis — two different cytokines, and tocilizumab can be used on its own without methotrexate.
At a glance
Key differences
- Different classes. Humira is a TNF inhibitor; Actemra is an IL-6 receptor antagonist. They act on different targets in the body.
- Time on the market. Humira was first approved by the FDA in 2002, Actemra in 2010. That gives Humira roughly 8 more years of real-world use and long-term safety data.
- Who markets them. Humira is marketed by AbbVie; Actemra by Genentech (Roche).
- 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.

ACTEMRA ® (tocilizumab) is an interleukin-6 (IL-6) receptor antagonist indicated for treatment of: Rheumatoid Arthritis (RA) ( 1.1 ) Adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response to one or more Disease-Modifying Anti-Rheumatic Drugs (DMARDs). Giant Cell Arteritis (GCA) ( 1.2 ) Adult patients with giant cell arteritis. Systemic Sclerosis-Associated Interstitial Lung Disease (SSc-ILD) ( 1.3 ) Slowing the rate of decline in pulmonary function in adult patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) Polyarticular Juvenile Idiopathic Arthritis (PJIA) ( 1.4 ) Patients 2 years of age and older with active polyarticular juvenile idiopathic arthritis.

How each one works
12.1 Mechanism of Action Adalimumab binds specifically to TNF-alpha and blocks its interaction with the p55 and p75 cell surface TNF receptors. Adalimumab also lyses surface TNF expressing cells in vitro in the presence of complement. Adalimumab does not bind or inactivate lymphotoxin (TNF-beta). TNF is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Elevated concentrations of TNF are found in the synovial fluid of patients with RA, JIA, PsA, and AS and play an important role in both the pathologic inflammation and the joint destruction that are hallmarks of these diseases. Increased concentrations of TNF are also found in psoriasis plaques. In P…
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.
