“Biotech company Celgene Corp. this week sent a letter to doctors warning that a study of its drug to treat dangerous blood clots suggests it may increase the risk of death in elderly patients. The letter, posted late Wednesday on the Web site of the Food and Drug Administration, recommends that doctors consider alternatives to Innohep in patients with deep vein thrombosis, life-threatening blood clots in major veins such as in the legs.” [Link]
