**Item 2.02 Results of Operations and Financial Condition**

On March 30, 2023, AcelRx Pharmaceuticals, Inc. (the "Company") issued a press release announcing its financial results for the three and twelve months ended December 31, 2022 and providing a corporate update (the "Release"). A copy of the Release is furnished herewith as Exhibit 99.1.

*The information contained in this Item 2.02 and in Exhibit 99.1 shall be deemed to be* "*furnished*" *and shall not be deemed to be* "*filed*" *for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the* "*Exchange Act*"*), or otherwise subject to the liabilities of that Section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended (the* "*Securities Act*"*). The information contained in this Item 2.02 and in Exhibit 99.1 shall not be incorporated by reference into any filing under the Securities Act or the Exchange Act made by the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing, except as shall be expressly set forth by specific reference in such filing.*

**Item 4.02. Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed**

**Interim Review.**

In connection with the Company's year-end financial statement close and preparation of its Annual Report on Form 10-K for the year ended December 31, 2022, an error in the earnings per share calculations was identified in the interim financial statements (the "Prior Period Financial Statements") for the three and six months ended June 30, 2022 and nine months ended September 30, 2022 (the "Interim Periods"). The error in the earnings per share calculation was due to the Company not properly applying the two-class method of calculating earnings per share with respect to, or disclose that, the warrants issued in November 2021 are participating securities. The financial statements for the year ended December 31, 2021 and the three months ended March 31, 2022, did not require the application of the two-class method of calculating earnings per share, and therefore were not impacted by the issuance of the warrants in November 2021.

The error has no impact on the Company's cash balance, liquidity, revenues, operating expenses, or total net income. Further, there is no impact to the Company's balance sheet accounts or cash flows.

On March 30, 2023, the Company's management and the Audit Committee of the Company determined that the Company's Prior Period Financial Statements for the Interim Periods, should no longer be relied upon because of the error in the earnings per share calculations. The Company's management and the Audit Committee concluded that it is appropriate to restate the Prior Period Financial Statements for the Interim Periods noted above. The correction of this error will be reflected in the Company's financial statements to be filed on Form 10-K for the year ended December 31, 2022.

**AcelRx Pharmaceuticals Reports Full Year and Fourth Quarter 2022 Financial Results and Provides Corporate Update**

*Divestment of DSUVIA*® *to Alora Pharmaceuticals expected to close the week of April 3, 2023*

*AcelRx advancing its proprietary Niyad*™ *nafamastat program with FDA Breakthrough designation in line with a strategic focus on late-stage assets*

*Near-term corporate milestones expected by the end of Q2 2023 include Niyad Emergency Use Authorization submission and the filing of a New Drug Application for Fedsyra*™*, the first of two pre-filled syringe product candidates* 

*$20.8 million in cash and short-term investments as of December 31, 2022*

*Webcast and conference call to be held today at 4:30 p.m. EDT*

HAYWARD, Calif., March 30, 2023 -- 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 full year and fourth quarter 2022 financial results and provided a corporate update.

"We are pleased to have signed an agreement to divest DSUVIA to Alora Pharmaceuticals, a well-resourced commercial partner, to expand the reach of this innovative product," stated Vince Angotti, Chief Executive Officer of AcelRx. "Alora has extensive experience commercializing products in hospitals, expertise in the manufacturing and sales of controlled substances and a team of over 200 salespersons. In addition, we believe the opportunity to receive a 75% royalty on net sales to the Department of Defense, the single largest customer of DSUVIA, will drive long-term value for our shareholders. With this transaction, we have continued to reduce costs while leveraging our clinical development and regulatory expertise to achieve the near-term milestones related to our late-stage development pipeline."

------

Mr. Angotti continued, "We believe that the accelerated stability testing of Niyad, our lead nafamostat product candidate, has produced data to support a planned Emergency Use Authorization submission in the second quarter and to support initiation of the single registrational trial in the second half of 2023. Our recent market research continues to confirm the urgent medical need for an alternative anticoagulant for use in continuous renal replacement therapy, or CRRT. From this data, we believe the opportunity for Niyad is approximately 60% of the CRRT market. In addition, we are prepared to submit an NDA for Fedsyra, our ephedrine pre-filled syringe (PFS) product candidate, by the end of next quarter. Both the Niyad and Fedsyra regulatory submissions will bring us closer to delivering important advancements for the healthcare system and increased value for our shareholders."

**2022 Fourth Quarter and Recent Corporate Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;● Accelerated stability testing of Niyad at elevated temperatures has produced data for our near-term EUA submission and initiation of the single registrational clinical trial expected to start in the second half of 2023.

&nbsp;&nbsp;&nbsp;&nbsp;● In December 2022, AcelRx sponsored a quantitative market research study of current CRRT practices among 150 U.S. physicians which demonstrated an urgent need for alternative anticoagulants other than citrate and heparin. Due to side effects of citrate and heparin, 29% of patients receive no anticoagulant during CRRT, which is below the international standard of care. When no anticoagulant is used, over 80% of the physicians reported blood clotting the dialysis filter, which can lead to the patient requiring transfusions and increased filter changes. Despite physicians reporting significant side effects with the use of citrate, it is used in 28% of CRRT patients. The Company believes the market opportunity for Niyad includes patients that are receiving no anticoagulant as well as those that are receiving citrate, totaling 57% of CRRT patients. The Company plans to submit the study data for publication in the second quarter of 2023.

------

&nbsp;&nbsp;&nbsp;&nbsp;● In December 2022, AcelRx entered into an agreement with a life sciences-focused investment fund for the sale of shares of its common stock, pre-funded warrants and common warrants. Gross proceeds from the offering were approximately $7.5 million.

&nbsp;&nbsp;&nbsp;&nbsp;● 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 commencing in the first half of 2023.

**Recent Publications**

&nbsp;&nbsp;&nbsp;&nbsp;● In March 2023, AcelRx announced the publication of a report arising from a series of rhinology procedures successfully performed using sufentanil sublingual tablet 30 mcg (SST; DSUVIA) in *Otolaryngology Case Reports*. The study was lead-authored by otolaryngologist Dr. Ashley Sikand and entitled "Evaluation of Sufentanil Sublingual Tablet 30 mcg for Perioperative Pain Management of In-Office Rhinology Procedures." The study demonstrated that DSUVIA can help manage acute pain during rhinology surgery in an office-based setting with a well-tolerated side-effect profile.

&nbsp;&nbsp;&nbsp;&nbsp;● In December, AcelRx announced a study published in the *Journal of Clinical Medicine* Special Issue "Advances in Postoperative Pain Management and Postoperative Chronic Pain". The study was lead-authored by orthopedic surgeon Dr. Andrea Angelini and entitled "Sublingual Sufentanil Tablet System for Postoperative Analgesia After Orthopedic Surgery: A Retrospective Study". The study was conducted by investigators at the University of Padova in Italy and retrospectively analyzed a total of 71 patients with respect to quality of postoperative pain management following total knee arthroplasty (TKA). Investigators analyzed data from 50 patients who received sufentanil sublingual tablets (SSTs) postoperatively versus a control group of 21 patients who were treated according to standard pain management protocol with continuous femoral nerve block. Adverse events were noted as being consistently lower in the group administered SSTs, and this was most notably observed to be the case with nausea (10% versus 30%), typically the most frequently reported adverse event with postoperative opioid administration.

------

&nbsp;&nbsp;&nbsp;&nbsp;● In October, an abstract, entitled, "Experience in Complex Outpatient Plastic Surgery Procedures Using Sufentanil Sublingual Tablets" was presented by Jeffrey DeWeese, M.D., FACS, at *Plastic Surgery The Meeting 2022*, held October 27-30, in Boston, MA. The study, conducted in 324 patients undergoing complex plastic surgery procedures, demonstrated the ability to perform such procedures using DSUVIA without general anesthesia, allowing for a rapid discharge time.

&nbsp;&nbsp;&nbsp;&nbsp;● Also in October, the Company announced two abstracts were 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 managing 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.

**Fourth Quarter 2022 Financial Information**

&nbsp;&nbsp;&nbsp;&nbsp;● The cash, cash equivalents and short-term investments balance was $20.8 million as of December 31, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;● Fourth quarter 2022 DSUVIA net sales were $0.3 million. Full year DSUVIA net sales for 2022 were $1.8 million, representing a 76% increase over the same period in 2021.

&nbsp;&nbsp;&nbsp;&nbsp;● Combined R&D and SG&A expenses for the fourth quarter of 2022 totaled $7.3 million compared to $6.9 million for the fourth quarter of 2021. Excluding non-cash depreciation and stock-based compensation expense, these amounts were $6.6 million for the fourth quarter of 2022, compared to $5.6 million for the fourth quarter of 2021. The increase in combined R&D and SG&A expenses in the fourth quarter of 2022 was primarily due to allocated financing transaction related costs attributed to the accounting for the warrant issued in the December 2022 financing, partially offset by other net decreases in R&D and SG&A expenses compared to the fourth quarter of 2021.

&nbsp;&nbsp;&nbsp;&nbsp;● Net loss attributable to common shareholders for the fourth quarter of 2022 was $7.5 million, or $1.00 per basic and diluted share, compared to a net loss of $7.9 million, or $1.24 per basic and diluted share, for the fourth quarter of 2021.

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 Alora Pharmaceuticals, LLC**

Alora Pharmaceuticals, LLC is the parent company of six specialty pharmaceutical and pharmaceutical manufacturing companies. Alora is headquartered in Alpharetta, GA. Alora is the parent company of the following organizations that comprise the Alora family of companies, Avion Pharmaceuticals, Acella Pharmaceuticals, Osmotica Pharmaceuticals, Sovereign Pharmaceuticals, Trigen Laboratories and Vertical Pharmaceuticals.

**About DSUVIA (sufentanil sublingual tablet), 30 mcg**<br> 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.
