March 17, 2008 - Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) announced that following a planned review by an independent Echocardiographic Data Safety Monitoring Board (EDSMB) it is continuing BLOOM (Behavioral modification and Lorcaserin for Overweight and Obesity Management), a pivotal trial evaluating the efficacy and safety of lorcaserin hydrochloride for the treatment of obesity. The EDSMB's review of unblinded echocardiographic data performed after patients completed 12 months of dosing in the trial confirmed that differences, if any, in the rates of Food and Drug Administration (FDA)-defined valvulopathy in patients treated with lorcaserin and in the control group did not meet the EDSMB's predetermined stopping criteria. Based on the EDSMB's review of the rate of FDA-defined valvulopathy, Arena has been able to confirm that the statistical power calculations used in the design of the Phase 3 trial program to monitor patients for increased risk of developing valvulopathy are justified. The findings from the month-12 review build on the EDSMB's September 2007 review that evaluated echocardiograms after 6 months of dosing. "This critical milestone assessing month-12 echocardiographic data strongly supports lorcaserin's cardiovascular safety profile. We believe that this exposure duration, even under a conservative interpretation of the literature, would have been sufficient to observe a fenfluramine like effect on heart valves if present. BLOOM's primary echo endpoint is based on the month-12 data," said Jack Lief, Arena's President and Chief Executive Officer. "We are committed to continued efforts to develop a robust database for submission to the FDA in our efforts to provide patients a novel, safe and effective obesity treatment."...
