Amgen Drug Tavneos’ Main Study Retracted by Medical Journal

The New England Journal of Medicine retracted a 2021 study on Amgen's Tavneos after an FDA investigation found that primary endpoint data for nine patients were altered following database lock and trial unblinding, and that these changes were not disclosed in the article.

The FDA's Center for Drug Evaluation and Research proposed in April to withdraw Tavneos from the market, citing a lack of substantial evidence of effectiveness and untrue statements of material fact in the original approval application submitted by ChemoCentryx, a wholly owned Amgen subsidiary.

Europe's medicines committee recommended revoking Tavneos' EU marketing authorization after concluding the Advocate study was conducted in breach of good clinical practice principles, with study data found to be incorrect and misleading.

The FDA identified 76 cases of drug-induced liver injury with reasonable evidence of a causal link to Tavneos between its 2021 approval and October 2024, including seven biopsy-confirmed cases of vanishing bile duct syndrome and eight deaths.

Amgen engaged the Duke Clinical Research Institute in February to independently review data from the phase 3 Advocate study, with findings to be submitted to the FDA by July 29 as part of a hearing request to keep Tavneos on the market.

Amgen said it remains confident in Tavneos' benefit-risk profile, citing more than 23 real-world studies involving over 1,200 patients, while noting the drug recorded $462 million in sales in 2025 before first-quarter 2026 sales fell 22% sequentially to $119 million.
