About AcelRx Pharmaceuticals, Inc.

AcelRx Pharmaceuticals, Inc. is a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute and breakthrough pain.  AcelRx's lead product candidate, Zalviso, is designed to solve the problems associated with post-operative intravenous patient-controlled analgesia which has been shown to cause harm to patients following surgery because of the side effects of morphine, the invasive IV route of delivery and the complexity of infusion pumps.  AcelRx has announced positive results from each of the three Phase 3 clinical trials for Zalviso and AcelRx anticipates submitting a New Drug Application with the FDA in the third quarter of 2013. AcelRx also announced positive top-line results for a Phase 2 trial for ARX-04, a sufentanil formulation for the treatment of moderate-to-severe acute pain, funded through a grant from U.S. Army Medical Research and Materiel Command.  The company has two additional pain treatment product candidates, ARX-02 and ARX-03, which have completed Phase 2 clinical development.  For additional information about AcelRx's clinical programs, please visit www.acelrx.com.
