Targacept Announces Results of Phase II Study of TC-2696 in Postoperative Dental Pain

WINSTON-SALEM, N.C.--(BUSINESS WIRE)--Dec 3, 2007 - Targacept, Inc. (NASDAQ: TRGT), a clinical-stage biopharmaceutical company developing a new class of drugs known as NNR Therapeutics (TM), today announced results of a randomized, placebo controlled Phase II clinical trial of its product candidate TC-2696. In the trial, 181 patients received a single dose of one of three doses of TC-2696 or ibuprofen or placebo following third molar extraction surgery. TC-2696 did not meet the primary endpoints, superior pain relief four or six hours after dosing as compared to placebo. TC-2696 was generally well tolerated in the trial, as there were no clinically meaningful differences in the incidence of adverse events between the TC-2696 dose groups and the placebo group and no unexpected or serious adverse events. These results suggest that TC-2696 is not a viable therapeutic candidate for acute post-operative pain.

In Targacept's preclinical studies, TC-2696 demonstrated analgesic activity in a variety of models, including acute, chronic and inflammatory nociceptive pain and neuropathic pain. Targacept is continuing to analyze the data from the trial and plans to consider next steps with regard to the development of TC-2696 in conjunction with GlaxoSmithKline, with which it entered into a strategic alliance focused in five therapeutic areas, including pain, earlier this year.
