Forest Laboratories, Inc. and Pierre Fabre Medicament Announce Positive Phase III Results with Levomilnacipran in Patients with Major Depressive Disorder

Forest Laboratories, Inc. (NYSE: FRX) and Pierre Fabre Medicament today announced preliminary top-line results from a Phase III study of levomilnacipran for the treatment of adults with major depressive disorder (MDD). Analyses of the data indicate a statistically significant improvement was achieved for levomilnacipran treated patients for all dose groups compared to placebo on the primary efficacy endpoint which was change from baseline to end of week 8 in the Montgomery-Asberg Depression Rating Scale-Clinician Rated (MADRS-CR) total score. Further analyses of the data are ongoing.

"Depressed patients often struggle to find the right antidepressant and the need for new medications is high. These positive Phase III results are very encouraging and support the continued research of levomilnacipran in adult patients with major depressive disorder,” said Dr. Marco Taglietti, Senior Vice President, Research & Development and President, Forest Research Institute.

This study is part of the ongoing development program for levomilnacipran for the treatment of MDD, which also includes a Phase III flexible-dose study reported in January 2011. Results from two additional placebo-controlled Phase III studies are expected at the end of this year and spring 2012, respectively.

About this Phase III Study

This was a randomized, double-blind, placebo-controlled, fixed-dose study evaluating the efficacy, safety and tolerability of levomilnacipran in patients with MDD. Following a 1-week single-blind, placebo run-in period, 724 men and women, 18 to 65 years of age, who met the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria for MDD and had a minimum score of 30 on the MADRS-CR, were randomized to receive levomilnacipran at 40, 80 or 120 mg once daily, or placebo for 8 weeks. This was followed by an additional 2-week double-blind down-taper period.

The primary analysis was performed using the Mixed-Effects Model Repeated Measure (MMRM) analysis. The placebo corrected difference in mean change from baseline to end of week 8 in MADRS-CR total score was: -3.2 (p=0.019), -4.0 (p=0.004) and -4.9 (p<0.001) in 40, 80, 120 mg groups, respectively.

Levomilnacipran was generally well-tolerated in the study. The most common adverse events (=10% and twice the rate of placebo) observed in the levomilnacipran dose groups were: nausea, constipation, increase in heart rate, and hyperhidrosis.
