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,
the Sufentanil NanoTab PCA System, 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.The NanoTab System has successfully completed all three of its
planned Phase 3 clinical trials and a New Drug Application submission is
planned for the third quarter of 2013. AcelRx has 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
