Forest Laboratories Submits Response for Lexapro(R) for Panic Disorder

NEW YORK, Aug. 26 /PRNewswire-FirstCall/ -- Forest Laboratories, Inc. (NYSE: FRX) announced today that it has submitted a complete response to deficiencies raised by the FDA Division of Neuropharmacological Drug Products in its review of the Panic Disorder supplemental NDA submitted for Lexapro in April, 2003. Lexapro is approved for use in Major Depressive Disorder and Generalized Anxiety Disorder. An additional Supplemental NDA is under FDA review for Social Anxiety Disorder.

The FDA notified Forest Laboratories on February 25, 2004 that the supplemental NDA for Panic Disorder was not approvable based on deficiencies with regard to the demonstration of efficacy. No safety issues were raised. The efficacy issues related to FDA concerns regarding the trial methods and statistical analyses performed for the two placebo-controlled trials provided in the submission. Both trials involved patients with panic disorder, the first was a European study which compared different doses of citalopram to placebo for 8 weeks of treatment followed by a one year extension phase; the second was a U.S. study which compared either escitalopram or citalopram to placebo for 10 weeks of treatment. These studies have previously been published.

Forest Laboratories believes it has fully addressed each of the FDA comments in its response and is hopeful that after additional FDA review, the panic disorder indication will be granted approval. The company believes that the panic disorder indication will not materially affect Lexapro sales.
