Now, though, the independent research committees overseeing the study are concerned about the ability of the study to continue and are considering what to do to prevent people from dropping out of the trial, Dr. Krall said.
The safety concerns were ignited by an analysis published Monday in The New England Journal of Medicine suggesting that Avandia, used to treat Type 2 diabetes, carries an increased risk of heart attack, estimated at 43 percent, compared with other diabetes drugs or placebos.
In response to the medical journal article, the Food and Drug Administration, issued a safety alert for Avandia and advised patients who take it to consult their doctors.
Avandia, which was approved by the F.D.A. in 1999, has been used by an estimated seven million people, six million of them in the United States.
Yesterday, the F.D.A. said its own recent analysis of more than 40 clinical studies of Avandia seemed to confirm the findings in The New...
