HAYWARD, Calif., May 16, 2022 /PRNewswire/ -- 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 first quarter 2022 financial results.

"DSUVIA continues to demonstrate solid sales growth and potential even with our limited commercial resources," stated Vince Angotti, Chief Executive Officer of AcelRx. "We remain steadfast in our belief in DSUVIA's value and its benefits to patients and healthcare providers with its unique pharmacokinetic characteristics, which are supported by favorable feedback received from physicians administering DSUVIA and numerous published studies. We believe that the uptake of this product will be maximized through a larger commercial infrastructure and, as such, we are in active discussions with potential partners that can execute a more robust commercial plan to support DSUVIA sales expansion, while further reducing AcelRx's operating costs."

Mr. Angotti continued, "Accordingly, we are aligning our cost structure to concentrate on our recently expanded development pipeline, which now includes our nafamostat portfolio and our pre-filled syringes. We believe these product candidates will provide multiple value-creating catalysts in the near-term, with two planned NDA submissions for the pre-filled syringes in 2022 and a potential emergency use authorization for Niyad in 2023. The reorganization of our corporate structure will drive shareholder value by extending our cash runway allowing us to continue progressing these development programs, remain focused on procedural suite sales and pursue further upside with a partner for DSUVIA."

First Quarter and Recent Highlights

• In May 2022, AcelRx reorganized to reduce headcount by approximately 40%, generating projected initial annual savings of $9 million.
• AcelRx announced the closing of its acquisition of Lowell Therapeutics, Inc. (Lowell) in January 2022 in a transaction for consideration of approximately $32.5 million plus net cash acquired and certain other adjustments, and which includes up to approximately $26.0 million of contingent consideration payable in cash or stock at AcelRx's option, upon the achievement of certain regulatory and sales-based milestones. Niyad™ (nafamostat) is the lead product, with a targeted indication of anticoagulation of the extracorporeal circuit, and which has received Breakthrough Device Designation from the FDA, as well as an ICD-10 procedural code from CMS which allows for reimbursement. Annual peak sales potential for Niyad is expected to exceed $200 million.
• In May 2022, AcelRx hosted a key opinion leader webinar highlighting the market for and benefits of Niyad and LTX-608 with two internationally renowned acute kidney injury experts, Stuart Goldstein, MD, from Cincinnati Children's Hospital, and Lakhmir Chawla, MD, former Chief of the Division of Intensive Care Medicine at the Washington D.C. Veterans Affairs Medical Center. https://www.acelrx.com/events/event-details/key-opinion-leader-kol-webinar-discuss-niyadtm-lyophilized-form-nafamostat
• As of March 31, 2022, AcelRx has achieved 855 DSUVIA formulary approvals. As of April 30, 2022, AcelRx has achieved 893 formulary approvals for DSUVIA.
• In the first quarter of 2022, AcelRx announced three publications, including: (1) a comparative data study between two different dialysis circuit anticoagulants in pediatric patients undergoing continuous renal replacement therapy (CRRT); (2) a study evaluating the use of a sufentanil sublingual tablet (SST) 30 mcg for management of pain of radiofrequency microneedling of the face or abdomen; and (3) a study evaluating real-world data in patients undergoing awake plastic surgery showing a rapid recovery time and minimal side effects with the use of SST for pain management.
• In March 2022, AcelRx received a close-out letter from the U.S. Food and Drug Administration (FDA) confirming that it had concluded its evaluation of the Company's corrective actions in response to the Warning Letter and that the Company had addressed the issues raised by the FDA Warning Letter dated February 11, 2021 regarding certain DSUVIA promotional materials.

Financial Information

• The cash, cash equivalents and short-term investments balance was $39.3 million as of March 31, 2022.
• First quarter 2022 net revenues were $0.4 million. DSUVIA units sold in the first quarter of 2022 were 10,530, compared to 8,960 units in the fourth quarter of 2021, reflecting unit sales growth of 18% from the prior quarter. Excluding fluctuating DoD revenues, unit sales growth was 64% in the first quarter of 2022 from the fourth quarter of 2021.
• Combined R&D and SG&A expenses for the first quarter of 2022 totaled $8.7 million compared to $8.6 million for the first quarter of 2021. Excluding non-cash depreciation and stock-based compensation expense, these amounts were $7.7 million for the first quarter of 2022, compared to $7.4 million for the first quarter of 2021. The increase in combined R&D and SG&A expenses in the first quarter of 2022 was primarily due to increased DSUVIA manufacturing-related costs, partially offset by reductions in personnel-related expenses.
• Net loss for the first quarter of 2021 was $8.7 million, or $0.06 per basic and diluted share, compared to $9.0 million, or $0.08 per basic and diluted share, for the first quarter of 2021.

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.

This release is intended for investors only.  For more information, including important safety information and black box warning for DSUVIA, please visit www.DSUVIA.com.

About nafamostat  Nafamostat is a broad spectrum, synthetic serine protease inhibitor with anticoagulant, anti-inflamatory and potential anti-viral activities. Niyad™ is a lyophilized formulation of nafamostat and is currently being studied under an investigational device exemption, or IDE, as an anticoagulant for the extracorporeal circuit, and has received Breakthrough Device Designation Status from the FDA. LTX-608 is a proprietary nafamostat formulation for direct IV infusion that will be investigated and developed as a potential anti-viral for the treatment of COVID, acute respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC) and acute pancreatitis.

About AcelRx Pharmaceuticals, Inc.
AcelRx Pharmaceuticals, Inc. is a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings.

The product candidates include: Zalviso® (sufentanil sublingual tablet system, SST system, 15 mcg), an investigational product in the U.S. being developed as an innovatively designed patient-controlled analgesia (PCA) system for reduction of moderate-to-severe acute pain in medically supervised settings; two pre-filled, ready-to-use syringes of ephedrine and phenylephrine licensed for the U.S. from Aguettant; Niyad™, a regional anticoagulant for the extracorporeal circuit; and LTX-608, for the potential treatment of COVID-19, disseminated intravascular coagulation, acute respiratory distress syndrome and acute pancreatitis.
