Meta-Analyses of Phase 3 Trials Show Obese and Overweight Patients Taking Arena Pharmaceuticals' Lorcaserin Achieved Statistically Significant Weight Loss
ISTANBUL, May 26, 2011 /PRNewswire/ -- Arena Pharmaceuticals, Inc. (NASDAQ: ARNA) today presented meta-analyses of the three trials in the lorcaserin Phase 3 clinical trial program at ECO 2011, the 18th European Congress on Obesity. The analyses show that lorcaserin caused statistically significant weight loss compared to placebo at one year among 7,500 obese and overweight, diabetic and non-diabetic adults. The lorcaserin-mediated weight loss was associated with favorable changes in biomarkers that may be predictive of cardiovascular and metabolic risk and in quality of life.
Christen M. Anderson, M.D., Ph.D., Arena's Vice President, Lorcaserin Development, stated, "We are pleased to have the opportunity to share and discuss the results from the lorcaserin Phase 3 program with the European medical community at ECO, and we look forward to submitting a Marketing Authorization Application for regulatory approval of lorcaserin in Europe next year."
At one year, using Modified Intent-to-Treat with Last Observation Carried Forward analysis (MITT-LOCF) of the integrated results, 46.3% of lorcaserin 10 mg twice daily (BID) patients and 40.6% of lorcaserin 10 mg once daily (QD) patients achieved at least 5% weight loss, compared to 22.1% of patients on placebo, and 22.0% of lorcaserin 10 mg BID patients and 17.3% of lorcaserin 10 mg QD patients achieved at least 10% weight loss, compared to 8.3% of patients on placebo. Of the patients completing year one of the trials, 62.3% of lorcaserin 10 mg BID patients and 52.8% of lorcaserin 10 mg QD patients achieved at least 5% weight loss, compared to 32.0% of patients on placebo, and 33.5% of lorcaserin 10 mg BID patients and 25.5% of lorcaserin 10 mg QD patients achieved at least 10% weight loss, compared to 13.8% of patients on placebo.
