Inspection of Alvotech’s Biosimilar Ends in Rejection

Share

FDA has issued Alvotech a complete response letter on its BLA for AVT05, a biosimilar to Janssen Pharmaceuticals’ Simponi (golimumab), in both prefilled syringe and autoinjector formats. The letter cited deficiencies identified during a July pre-license inspection of Alvotech’s Reykjavik manufacturing facility, according to the company. Alvotech says the issues must be resolved before the BLA can be approved, and the agency did not flag any other concerns with the application. The Reykjavik facility remains FDA-approved for production of currently commercialized products, it adds.

Simponi is approved for treating inflammatory conditions like rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis. Common side effects include infection, and serious risks include an increased risk of infections like tuberculosis, and other serious conditions like cancer or heart failure. The company says no biosimilars for Simponi have yet been approved in the U.S.
