Another Drug Bites the Dust: PargluvaTM

Last week, Bristol-Myers Squibb decided to halt development of its promising new diabetes drug, PargluvaTM (muraglitazar).

You may recall the news last September when an FDA advisory panel recommended the drug for approval. You may also recall an article in the Journal of the American Medical Association (JAMA) a month later that warned of Pargluva's link to increased risk for heart attack and stroke.

If approved, Pargluva would have become the first marketed drug in a relatively new class of compounds called glitazars. These drugs not only lower glucose, but can improve cholesterol levels. Both of these benefits were documented in a study appearing in this month's Diabetes Care which pitted Pargluva against a similar drug, Actos (pioglitazone).

In light of possible health risks associated with Pargluva, the FDA last year requested more information on the drug's cardiovascular safety profile. Bristol-Myers Squibb decided that the time required to run additional safety trials, up to 5 years, would not be worth the effort - given the diabetes drugs projected to become available in the coming years.
