Targacept Announces Negative Top-Line Results from Phase 2b Clinical Trial of TC-5619 in Schizophrenia
WINSTON-SALEM, N.C.--(BUSINESS WIRE)--Targacept, Inc. (NASDAQ: TRGT), a clinical-stage biopharmaceutical company developing novel NNR Therapeutics ™, today announced top-line results from a Phase 2b clinical trial of TC-5619 as an augmentation therapy for the treatment of negative symptoms of schizophrenia. In the trial, TC-5619 did not meet the primary outcome measure, change from baseline on the Scale for the Assessment of Negative Symptoms (SANS) after 24 weeks versus placebo. In addition, TC-5619 did not demonstrate improvement on the key secondary measures of cognitive function. TC-5619 exhibited a benign safety and tolerability profile in the study.
“The development of new and innovative treatments for patients suffering from central nervous system disorders is challenging, and the results of this study highlight the risks inherent in trying to address the unmet medical needs that remain in schizophrenia,” said Dr. Stephen A. Hill, Targacept’s President and Chief Executive Officer. “While the results are disappointing, we believe the study was well conducted and provides a robust dataset upon which we have based our decision to not pursue further development of TC-5619 as a treatment for either schizophrenia or Alzheimer’s disease. We will focus our efforts on our other ongoing Phase 2b programs, TC-5214 for overactive bladder and TC-1734 for Alzheimer’s disease, continue forward with the planned development of TC-6499 for diabetic gastroparesis, and maintain our disciplined approach to executing our business plan which seeks to provide new medicines to improve patients’ lives.”
About the TC-5619 Phase 2b Clinical Trial
The double blind, placebo controlled Phase 2b clinical trial was conducted at 64 sites across Eastern Europe and the United States. In the trial, 477 patients meeting DSM-IV criteria for schizophrenia, with stable psychotic symptoms and taking an approved atypical antipsychotic medication (except clozapine) were randomized to receive either one of two doses of TC-5619 (5mg or 50mg) or placebo together with continued treatment with an atypical antipsychotic. The study included a four-week screening period, followed by a 24-week treatment period. The primary efficacy outcome measure was the SANS, and key secondary outcome measures were the CogState Schizophrenia Battery (composite score) and the University of California, San Diego Performance-Based Skills Assessment, Brief Version. Safety and tolerability were also measured.
