Targacept Completes Recruitment in Phase 2b Schizophrenia Trial of TC-5619

WINSTON-SALEM, N.C.--(BUSINESS WIRE)-- Targacept, Inc. (NASDAQ: TRGT), a clinical-stage biopharmaceutical company developing novel NNR Therapeutics™, today announced that it has completed recruitment of patients in the Phase 2b study of TC-5619 as a treatment for negative symptoms and cognitive dysfunction in schizophrenia. The company expects to report top-line results from the study by the end of 2013. TC-5619 is a highly selective modulator of the alpha7 neuronal nicotinic receptor.

"I would like to thank the patients, study sites and investigators who have helped us reach this important milestone in the development of TC-5619 as a potential new treatment for schizophrenia," said Dr. Stephen A. Hill, Targacept's President and Chief Executive Officer. "Current schizophrenia therapies primarily impact positive symptoms of schizophrenia, leaving the negative symptoms and cognitive dysfunction largely untreated. A new and effective treatment that addresses this medical need would be critically important for the millions of schizophrenia patients unable to function in society."

The ongoing Phase 2b study is a double blind, placebo controlled, randomized, parallel group trial being conducted at sites in Eastern Europe and the United States. The primary outcome measure is the Scale for the Assessment of Negative Symptoms (SANS). Key secondary outcome measures include the CogState Schizophrenia Battery (composite score), a computerized test battery, and the University of California, San Diego Performance-Based Skills Assessment, Brief Version. The study is designed to randomize 456 patients with stable schizophrenia who are taking a fixed dose of an atypical antipsychotic. The study includes a 4-week screening period, followed by a 24-week treatment period during which patients receive one of two doses of TC-5619 (5mg or 50mg) or placebo once daily.

About Negative Symptoms and Cognitive Dysfunction in Schizophrenia

Schizophrenia is a chronic, severe and disabling form of psychosis. The disease generally includes three domains, positive symptoms, negative symptoms and cognitive dysfunction. The negative symptoms and cognitive dysfunction play a primary role in the inability of many schizophrenic patients to function normally. The market research firm Decision Resources estimated that there were approximately 4.7 million people with schizophrenia in the world's seven major pharmaceutical markets in 2011. Estimates as to the prevalence of schizophrenia patients who suffer from negative symptoms vary, and it has been estimated that up to 75% of patients with schizophrenia are cognitively impaired. There is currently no drug approved in the United States or Europe specifically for the treatment of negative symptoms of schizophrenia or cognitive dysfunction in schizophrenia.
