Panel to Rule on Safety of Diabetes Drug

GAITHERSBURG, Md. — A federal advisory panel will vote Wednesday on whether Avandia, a controversial diabetes medicine, is safe enough to remain on the market.

The panel heard a raft of conflicting scientific information on Tuesday not only from Avandia’s maker, GlaxoSmithKline, but also from feuding scientists within the Food and Drug Administration. An important issue is whether information from clinical trials conducted by GlaxoSmithKline can be believed. On Tuesday, panel members heard evidence that patients in a crucial trial of Avandia who suffered heart attacks did not have their problems included in the trial’s final tally. And internal company documents made public in recent days show that the company hid from the public crucial information about Avandia’s safety woes.

Some reviewers within the F.D.A. said Tuesday that studies demonstrate conclusively that Avandia is far more dangerous to the heart than a similar medicine, Actos, made by Takeda. But other reviewers said that the trials are far more equivocal and provide little evidence that Avandia is dangerous. Scientists at GlaxoSmithKline argued that Avandia is a safe and important option in the treatment of Type 2 diabetes.

Questions from some panel members on Tuesday hinted that skepticism about GlaxoSmithKline’s trustworthiness is shared by at least some of the advisers. But with most of the scientific presentations completed on Tuesday, panel members are expected to give far greater voice to their own views on Wednesday. A series of complex votes are scheduled for the afternoon.
