Clinical Data, Inc. Announces FDA Acceptance of New Drug Application for Vilazodone for the Treatment of Major Depressive

NEWTON, Mass.--(BUSINESS WIRE)-- Clinical Data, Inc. (NASDAQ: CLDA), today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing the Company’s New Drug Application (NDA) for vilazodone for the treatment of major depressive disorder (MDD). Vilazodone is a dual-acting potent and selective serotonin reuptake inhibitor and a 5-HT1A receptor partial agonist. The NDA will be subject to a standard review.

“The acceptance of the NDA for review by the FDA is another positive step toward our goal of bringing vilazodone to market, and if approved, vilazodone will offer a novel treatment to the millions of people suffering from depression,” said Carol R. Reed, M.D., Executive Vice President and Chief Medical Officer of Clinical Data.

The NDA submission is based on a comprehensive development program for vilazodone, which included two randomized, double-blind, placebo-controlled Phase III clinical trials. In both of these eight-week trials, the efficacy of vilazodone was shown to be superior to placebo with statistically significant results for the primary endpoint and for multiple secondary measures of the symptoms of depression. Results from efficacy measures in an uncontrolled 52-week study were consistent with these findings. The NDA is supported by a database of nearly 2,900 subjects.

Vilazodone was licensed from Merck Serono, a division of Merck KGaA, Darmstadt, Germany. Under the terms of Clinical Data’s license agreement with Merck Serono, the FDA’s acceptance of the NDA for vilazodone gives rise to a milestone payment to Merck KGaA of €12.5 million (or $15.6 million at May 21, 2010, the NDA acceptance date), payable in 920,901 shares of Clinical Data common stock to be issued within 30 days of the NDA acceptance date. All of the shares issued to Merck KGaA with respect to this milestone payment will be unregistered but carry certain demand and incidental registration rights as provided under the license agreement.

About Depression

Depression is a highly prevalent mood disorder with significant morbidity and mortality. The National Institute of Mental Health estimates that major depressive disorder affects approximately 18.1 million adults in the U.S. and that the medical and social costs of depression in the U.S. in the year 2000 was $83 billion, including both $26 billion in costs of treatment and $57 billion in losses such as absenteeism, reduced productivity at work, and the value of lifetime earnings lost due to suicide-related deaths. Further, approximately 60% of MDD patients have a comorbid psychiatric condition, such as anxiety-related disorders and posttraumatic stress disorder.1 Despite advances in the understanding of pharmacotherapy and the ongoing development of new agents, overall effectiveness is unsatisfactory and approximately two-thirds of patients do not achieve remission with first-line depression therapies.2 More than 212 million prescriptions were written for antidepressants in 2009, and commonly prescribed therapies accounted for approximately $12 billion in sales.3

About Vilazodone

Vilazodone is a novel, dual-acting potent and selective serotonin reuptake inhibitor and 5-HT1A receptor partial agonist in development for the treatment of major depressive disorder. Selective serotonin reuptake inhibitors, which enhance the availability of synaptic serotonin, are approved as safe and effective treatments for depression and 5-HT1A receptor partial agonists have also been shown to be effective for mood disorders including depression and anxiety. Nearly 2,900 patients have been exposed to vilazodone in the clinical development program. The efficacy of vilazodone in the treatment of MDD was shown to be superior to placebo in two randomized Phase III clinical trials. Results of an uncontrolled long-term safety study were consistent with the findings of the placebo-controlled studies. The most common adverse events associated with vilazodone in clinical trials were diarrhea, nausea, and insomnia. Vilazodone is currently not approved by the FDA.
