Key takeaways
Simponi (golimumab) and Enbrel (etanercept) are both injectable biologic medications used to treat autoimmune conditions, but they have some key differences. Simponi is a monoclonal antibody that blocks tumor necrosis factor (TNF) to reduce inflammation and doesn't currently have a biosimilar approved. It is used for conditions like rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ulcerative colitis (UC). Simponi is typically injected once a month, except for UC, which has a different dosing schedule. Enbrel, also a monoclonal antibody, binds to TNF to help with inflammation and is used for a variety of conditions such as RA, PsA, and childhood arthritis. Enbrel is typically injected once a week and has biosimilars approved but not available yet. Both medications raise the risk of serious infections and certain cancers, but Enbrel has a higher reported rate of injection site reactions and infections. Additionally, Enbrel can be stored at room temperature for up to 14 days, while Simponi can be stored at room temperature for up to 30 days.
