The FDA's move to pull Tavneos is fully justified — unblinded study personnel manipulated the pivotal clinical trial results to make the drug appear effective when the original analysis showed otherwise, and the applicant never disclosed that original analysis to regulators. Both the FDA and the EU's CHMP have concluded the drug's benefits are no longer proven, making continued market presence a serious public health risk. Newly identified cases of fatal liver injury, including vanishing bile duct syndrome, only deepen the case for removal.
Pulling Tavneos ignores nearly five years of real-world evidence from over 1,200 patients across 23 published studies showing the drug supports remission, reduces relapse risk and cuts harmful glucocorticoid exposure for people with a devastating, life-threatening disease. Hepatic risks are serious but manageable with established monitoring protocols already built into the label. As the only FDA-approved targeted oral treatment for severe active GPA and MPA, removing it leaves patients with no comparable alternative.
