Transcept Pharmaceuticals, Inc. (Nasdaq: TSPT) today announced that it is scheduled to meet with the U.S. Food and Drug Administration (FDA) on January 20, 2010 to discuss the Complete Response Letter regarding the New Drug Application (NDA) for Intermezzo® (zolpidem tartrate sublingual tablet).

Following the receipt of official FDA minutes of the meeting, Transcept plans to provide an update on its discussions with the FDA and the status of the anticipated Intermezzo® NDA resubmission.
