Another Study Says Arena Pharmaceuticals, Inc. Diet Pill Beats Placebo

The experimental weight-loss drug lorcaserin may spur modest weight loss without the heart risks of some older drugs, a new clinical trial confirms -- though whether the medication will ever reach the market remains up in the air. Last October, the U.S. Food and Drug Administration (FDA) declined to approve lorcaserin as an obesity treatment, citing research in rats that suggested there could be a cancer risk. This latest study, reported in the Journal of Clinical Endocrinology and Metabolism, backs up earlier research showing that lorcaserin can shave off some extra pounds.
