Novacea Stockholders Approve Merger With Transcept

South San Francisco, California, January 27, 2009 -- Novacea, Inc. (Nasdaq: NOVC) announced today that its stockholders approved the proposals to complete the proposed merger with Transcept Pharmaceuticals, Inc. at a special meeting of stockholders held earlier in the day. The merger is expected to close after satisfaction or waiver of all closing conditions specified in the merger agreement, which is currently expected to occur within the next week. Immediately following completion of the merger, Novacea will change its name to Transcept Pharmaceuticals, Inc. and common stock in the combined company will trade on The NASDAQ Global Market® under the symbol "TSPT". The merger of Novacea and Transcept will result in a NASDAQ-listed specialty pharmaceutical company focused on the development and commercialization of proprietary products that address important therapeutic needs in the fields of psychiatry and sleep medicine. The lead Transcept product candidate, Intermezzo®, is a sublingual low dose formulation of zolpidem that has been developed for use as-needed for the treatment of insomnia when a middle of the night awakening is followed by difficulty returning to sleep. Intermezzo® Phase 3 clinical trials have been completed and, on September 30, 2008, Transcept submitted a New Drug Application for Intermezzo® to the U.S. Food and Drug Administration, which was accepted for filing on December 15, 2008. The related Prescription Drug User Fee Act (PDUFA) date is scheduled for July 30, 2009.

John P. Walker, Novacea’s Chief Executive Officer and Chairman of the Board, commented, "I appreciate the vote of the Novacea stockholders who share the belief of our board and management team that Transcept represents a compelling opportunity for value creation. The management of Transcept, led by Glenn Oclassen, has a demonstrated track record of success in partnering and commercially launching specialty pharmaceutical products. Intermezzo® potentially represents a significant new opportunity in the insomnia market and, if approved, is positioned to be the first sleep therapeutic for use as-needed at the time of middle of the night awakening. We believe that the capital resources of the merged company give it the potential to reach significant value creating milestones, including the anticipated FDA approval of Intermezzo® in 2009 and corporate collaborations in the U.S. and in other world markets. As a member of the merged company’s Board of Directors, I look forward to working with Glenn and his management team as they take Transcept forward to capitalize fully on this opportunity."
