HAYWARD, Calif., August 11, 2022 – AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), (AcelRx), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today reported its second quarter 2022 financial results.

“Our commercial emphasis on procedural suites has resulted in a successful quarter of growth for DSUVIA, while also reducing our costs, allowing us to focus on our robust pipeline,” stated Vince Angotti, Chief Executive Officer of AcelRx. “DSUVIA continues to demonstrate solid sales growth in the procedural suite setting, with adoption beginning across national accounts. Our European partner, Aguettant, also is gearing up for the launch of DZUVEO. This said, we remain mindful of our operating costs and plan to continue reducing our cash burn. Importantly, we remain in discussions with potential partners with the commercial resources to amplify the expected growth for DSUVIA.”

Mr. Angotti continued, “We’re focused on a potential Emergency Use Authorization for our lead nafamostat candidate, Niyad™, in 2023 as we are making solid progress across the supply chain. Additionally, our pre-filled syringes remain on track for NDA submissions this year. We believe each of these product candidates will provide multiple value-creating catalysts in the near-term.”

About DSUVIA (sufentanil sublingual tablet), 30 mcg
DSUVIA®, known as DZUVEO® in Europe, is indicated for use in adults in certified medically supervised healthcare settings, such as hospitals, surgical centers, and emergency departments, for the management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. DSUVIA was designed to provide rapid analgesia via a non-invasive route and to eliminate dosing errors associated with intravenous (IV) administration. DSUVIA is a single-strength solid dosage form administered sublingually via a single-dose applicator (SDA) by healthcare professionals. Sufentanil is an opioid analgesic previously only marketed for IV and epidural anesthesia and analgesia. The sufentanil pharmacokinetic profile, when delivered sublingually, avoids the high peak plasma levels and short duration of action observed with IV administration. DZUVEO has been approved by the European Medicines Agency and AcelRx's European commercialization partner, Aguettant, will market the drug in Europe.
