Targacept Announces Revised Top-Line Results from Exploratory Phase 2 Study of TC-6987 in Asthma

WINSTON-SALEM, N.C.--(BUSINESS WIRE)--Apr 10, 2012 - Targacept, Inc. (NASDAQ: TRGT), a clinical-stage biopharmaceutical company developing novel NNR Therapeutics™, today announced revised top-line results from its exploratory Phase 2 clinical study of TC-6987 in asthma.

Following identification of an error in the application of the agreed statistical analysis plan, a reanalysis of the data was undertaken. As shown in the table below, as compared to the initially reported values, the reanalysis revealed a 2 ml decrease in the change in Forced Expiratory Volume (FEV1) from baseline to pre-dosing on day 28, which resulted in TC-6987 no longer achieving the study's protocol-defined success criteria on that co-primary endpoint. However, TC-6987 continued in the reanalysis to meet protocol-defined success criteria on the study's other co-primary endpoint, change in FEV1 from baseline to two hours post-dosing on day 28. Reanalysis of the post-dose measure revealed an incrementally stronger signal of a drug effect than the initial analysis.

“As I said previously, this exploratory study in asthma accomplished our goal of detecting in patients a signal of the potential of NNR Therapeutics in the treatment of disorders outside of the CNS. We are in the process of considering potential next steps for this compound and indication,” said J. Donald deBethizy, Ph.D., Targacept's President and Chief Executive Officer. “We regret not having discovered the statistical analysis error initially.”

About the Study

The study was a double blind, placebo controlled, parallel group Phase 2 trial conducted at 23 sites in the United States. The study enrolled 93 adult patients with persistent mild to moderate asthma that were being treated with inhaled corticosteroids, and 90 patients completed the study. The study design provided for a four-week wash-out period during which patients received a low-dose inhaled corticosteroid while discontinuing their current asthma medication (other than permitted rescue mediation). Patients were then randomized into one of two cohorts and received either placebo or oral TC-6987 once daily, together with the low-dose inhaled corticosteroid, for four weeks. Patients in the TC-6987 cohort received a 100mg dose the first day of dosing and then a 50mg dose for the remainder of the dosing period. The study concluded with a two-week follow-up period.
