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 ARX-01 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. ARX-01 has successfully completed two of its three planned
Phase 3 clinical trials and a New Drug Application submission is planned for
the third quarter of 2013. AcelRx recently completed enrollment in a Phase 2
study 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, and top-line results are expected in the second
quarter of 2013. 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
