Forward Looking Statements

This presentation contains forward-looking statements, including, but not limited to, statements related to future financial results, potential proceeds under the Grunenthal agreement, the process and timing of anticipated future development of AcelRx’s product candidates, including Zalviso, the NDA submission and the CRL, the recent meeting held with the FDA to discuss the CRL, AcelRx’s plans to address the issues raised in the CRL, and anticipated resubmission of the Zalviso NDA to the FDA, including the scope of the resubmission and the timing of the resubmission and FDA review time, the impact, if any, of the FDA’s review of the amendments to the Zalviso NDA that were not previously reviewed, planned initiation of the Phase 3 clinical trial for ARX-04, and the therapeutic and commercial potential of AcelRx Pharmaceuticals’ product candidates, including Zalviso. These forward-looking statements are based on AcelRx Pharmaceuticals’ current expectations and inherently involve significant risks and uncertainties. AcelRx Pharmaceuticals’ actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, which include, without limitation, risks related to: AcelRx Pharmaceuticals’ ability to receive regulatory approval for Zalviso; any delays or inability to obtain and maintain regulatory approval of its product candidates, including Zalviso, in the United States and Europe; AcelRx’s ability to build an effective commercial organization; its ability to receive any milestones or royalty payments under the Grunenthal agreement; its ability to obtain sufficient financing to commercialize Zalviso and proceed with clinical development of ARX-04; the success, cost and timing of all product development activities and clinical trials, including the planned Phase 3 ARX-04 trial; the market potential for its product candidates; the accuracy of AcelRx’s estimates regarding expenses, capital requirements and needs for financing; and other risks detailed in the “Risk Factors” and elsewhere in AcelRx Pharmaceuticals’ U.S. Securities and Exchange Commission filings and reports, including its Quarterly Report on Form 10-Q filed with the SEC on November 10, 2014. AcelRx Pharmaceuticals undertakes no duty or obligation to update any forward-looking statements contained in this release as a result of new information, future events or changes in its expectations.

Zalviso NDA Status-CRL received July 25, 2014

Major items in CRL:

Demonstration of a reduction in the incidence of optical system errors

Optical system errors were noted in the clinical setting at a single digit rate Did not appear to impact Phase 3 safety and efficacy results Improvements have been made to reduce error rate Additional bench testing to be completed to confirm error rate reduction

Changes to the Instructions for Use (IFU) to address inadvertent dosing

15 misplaced tablets of ~30,000 doses IFU modified to address this issue

HF studies will be required to confirm IFU/GUI changes are adequate

Support for shelf life (not approvability issue)

Data to be provided to support 24 month dating
