HAYWARD, Calif., November 14, 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 third quarter 2022 financial results.

“We have continued to reduce costs and advance the portfolio as planned. We have progressed our lead nafamostat product candidate, Niyad™ to prepare for a potential Emergency Use Authorization in the first half of 2023 and initiated early commercial planning to ensure we’re prepared for a potential launch next year,” stated Vince Angotti, Chief Executive Officer of AcelRx. “Additionally, we expect to submit our ephedrine pre-filled syringe NDA by the end of this year, with the second pre-filled syringe product submission planned for the first half of next year to ensure we have multiple potential commercial products available by the end of 2023.”

Mr. Angotti continued, “Related to DSUVIA^®, our commercial focus in the third quarter remained on procedural suites, demonstrating continued year-over-year growth despite the significant reduction in the size of our commercial organization. We expect to finalize an agreement for DSUVIA by the end of the year with a strategic partner that can more fully maximize the DSUVIA opportunity with additional resources. Our European partner, Aguettant, recently launched DZUVEO^® in Europe, further extending the commercial footprint of our novel sufentanil sublingual tablet.”

Third Quarter and Recent Highlights

● The initial development batch of Niyad was successfully produced earlier this month in preparation for the potential Emergency Use Authorization in the first half of 2023.

● In October, the Company announced the European Launch of DZUVEO by its partner, Aguettant across key European countries, with commercialization in Spain, Portugal and Italy expected to begin in the first half of 2023.

● In October, the Company announced the podium presentation of a study of DSUVIA in a large cohort of patients undergoing plastic surgery procedures entitled, "Experience in Complex Outpatient Plastic Surgery Procedures Using Sufentanil Sublingual Tablets". The study, conducted in 324 plastic surgery cases, was presented on October 28th by Jeffrey DeWeese, M.D., FACS, at Plastic Surgery The Meeting 2022, held October 27-30, in Boston, MA. The study found many positive benefits of using DSUVIA, including the ability to perform complex, extensive cosmetic procedures without general anesthesia, allowing for a rapid discharge time.

● In October, the Company announced two abstracts presented at the ANESTHESIOLOGY® Annual Meeting 2022. The first presentation was of an investigator-initiated trial demonstrating the advantages of sufentanil sublingual tablet versus intravenous opioids for postoperative spine surgery pain and the second was a presentation by the Uniformed Services University of the Health Sciences on DSUVIA for battlefield pain management.

Financial Information

● The cash, cash equivalents and short-term investments balance was $20.9 million as of September 30, 2022.

● Third quarter 2022 DSUVIA net sales were $0.5 million, a 217% increase over 2021; year-to-date September 30, 2022 DSUVIA net sales were $1.5 million, representing a 51% increase over the same period in 2021. Total DSUVIA units sold in the third quarter of 2022 were 1,032 compared to 371 units in 2021. Total net revenues in the third quarter 2022 of $0.5 million declined $1.4 million compared to the same period in 2021 due to the recognition of $1.7 million in revenues in the third quarter of 2021 attributed to an upfront payment received related to our DZUVEO European licensing agreement.

● Combined R&D and SG&A expenses for the third quarter of 2022 totaled $6.6 million compared to $10.1 million for the third quarter of 2021. Excluding non-cash depreciation and stock-based compensation expense, these amounts were $5.7 million for the third quarter of 2022, compared to $8.6 million for the third quarter of 2021. The decrease in combined R&D and SG&A expenses in the third quarter of 2022 was primarily due to overall cost reductions principally focused on DSUVIA-related commercial expenses.

● Net loss attributable to common shareholders for the third quarter of 2022 was $6.9 million, or $0.94 per basic and diluted share, compared to a net loss of $8.4 million, or $1.40 per basic and diluted share, for the third quarter of 2021.

About DSUVIA (sufentanil sublingual tablet), 30 mcg
DSUVIA®, branded 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/DZUVEO was designed to provide rapid analgesia via a non-invasive route and to eliminate dosing errors associated with intravenous (IV) administration. DSUVIA/DZUVEO 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, markets the drug in Europe.
