A clinical trial, originally published in 2021, which was used to approve Amgen's Tavneos was retracted Monday from the New England Journal of Medicine at the request of two of the study's authors, the journal said Monday. "The two academic authors of the article by Jayne et al., Avacopan for the Treatment of ANCA-Associated Vasculitis, N Engl J Med 2021;384:599-609, request retraction of the article because, according to an ongoing Food and Drug Administration investigation conducted after publication, and without the knowledge of these two authors, the primary end-point assessments in nine patients were readjudicated after database lock and trial unblinding. This was not disclosed in the article and is inconsistent with proper research conduct. The editors therefore retract the article," the NEJM stated in a retraction notice.
