The Food and Drug Administration has cleared adalimumab-afzb (Abrilada) as the fifth approved Humira biosimilar and the 25th approved biosimilar drug overall, the agency said in a Nov. 15 announcement.
According to a press release from Pfizer, approval for Abrilada was based on review of a comprehensive data package demonstrating biosimilarity of the drug to the reference product. This included data from a clinical comparative study, which found no clinically meaningful difference between Abrilada and the reference in terms of efficacy, safety, and immunogenicity in patients with moderate to severe rheumatoid arthritis (RA). In addition to RA, Abrilada is indicated for juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, adult Crohn’s disease, ulcerative colitis, and plaque psoriasis.
Common adverse events in adalimumab clinical trials included infection, injection-site reactions, headache, and rash.
Pfizer said that it “is working to make Abrilada available to U.S. patients as soon as feasible based on the terms of our agreement with AbbVie [the manufacturer of Humira]. Our current plans are to launch in 2023.”
