March 15, 2021

/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 fourth quarter and full year 2020 financial results.

“Last year we achieved many important milestones and objectives that set the foundation for the growth of DSUVIA® in 2021 and beyond, despite the global pandemic,” said

Vince Angotti

, Chief Executive Officer of AcelRx. “Like many other companies in our space, COVID has had an impact on the pace of approvals and adoption of DSUVIA as formulary review meetings and elective surgeries have been postponed.  However, with vaccine rollouts and elective surgeries ramping up, we expect formulary approvals in the second half of 2021 to be back to the accelerating rate we saw before the pandemic. Importantly, we expect data from ongoing and upcoming studies this year to continue to demonstrate the unique characteristics of DSUVIA that benefit the patient and institutions alike.”

FY 2020 and Recent Highlights

• In March, AcelRx announced an agreement with Brigham and Women’s Hospital for an investigator-initiated study of DSUVIA led by
  
  Richard D. Urman
  
  MD, MBA, Associate Professor of Anesthesia and co-director of the Center for Perioperative Research at Brigham and Women’s Hospital and
  
  Harvard Medical School
  
  . This study is ongoing and is evaluating the perioperative use of DSUVIA in patients undergoing spine surgery compared to their standard intravenous (IV) opioid regimen.
• In April, DSUVIA achieved Milestone C approval from the Department of Defense (DoD), a decision that approves DSUVIA for use in all U.S. Army sets, kits and outfits (SKOs). Initial stocking orders have begun for U.S. Army SKOs and are expected to approximate
  
  $30 million
  
  over the next three years, dependent on troop deployment schedules.
• In July, AcelRx entered into a distribution agreement with Zimmer Biomet to market DSUVIA within the dental and oral surgery markets in
  
  the United States
  
  exclusively through Zimmer Biomet’s Dental division. The formal launch is planned in 2021 and will expand once Zimmer Biomet receives necessary licenses. The estimated applicable market in dental surgeries is 7.5 million annual procedures.
• In August, AcelRx announced the publication of a study entitled, “Reduced Opioid Use and Reduced Time in the Postanesthesia Care Unit Following Preoperative Administration of Sublingual Sufentanil in an Ambulatory Surgery Setting,” by
  
  Christian Tvetenstrand
  
  , MD and
  
  Michael Wolff
  
  , MD, in the
  
  Journal of Clinical Anesthesia and Pain Management
  
  . Highlights of the publication included a greater than 50% overall reduction in opioids administered perioperatively and a 34% reduction in postanesthesia care unit (PACU) time in the DSUVIA-treated patients compared to historical controls. See Cautionary Statements section below.
• In August, AcelRx announced an investigator-initiated study with Cleveland Clinic evaluating the effects of DSUVIA on post-operative recovery from orthopedic surgery. This double-blind study is ongoing and compares DSUVIA to IV fentanyl for patients undergoing knee arthroscopy.
• In September, AcelRx announced that the U.S. military’s access to DSUVIA was expanded with the addition of DSUVIA to the DoD Joint Deployment Formulary.
• In September, the U.S. Army awarded AcelRx a contract for up to
  
  $3.6 million
  
  over four years for the purchase of DSUVIA to support a DoD study to aid the development of clinical practice guidelines.
• In December, AcelRx announced the publication of clinical data in an article in the
  
  Journal of Universal Surgery
  
  entitled, “A Medication Use Evaluation of Sufentanil Sublingual Tablet 30 mcg for the Perioperative Management of Surgical Pain,” by lead author
  
  Koth Cassavaugh
  
  , PharmD, Director of Pharmacy, which reported that perioperative dosing of DSUVIA can provide more rapid PACU recovery times compared to standard IV opioid administration. In addition, patients in the control group received 66% higher mean dosing of intraoperative IV opioids compared to patients receiving DSUVIA and postoperative opioid use for the DSUVIA group was less than half of the control IV opioid group, with orthopedic surgery patients having the largest decrease (69%). See Cautionary Statements section below.
• In January and
  
  February 2021
  
  , AcelRx issued approximately
  
  $36.3 million
  
  of stock through an underwritten public offering and under its At-the-Market sales agreement.
• In
  
  January 2021
  
  , AcelRx announced an investigator-initiated study with University Hospitals Cleveland Medical Center to evaluate the postoperative use of DSUVIA in a prospective cohort of patients undergoing cardiac surgery with cardiopulmonary bypass following a specialized enhanced recovery protocol.
• In
  
  February 2021
  
  , AcelRx announced an investigator-initiated study with Newport Plastic and Reconstructive Surgery Center analyzing data from the historical use of DSUVIA for various same-day plastic surgery procedures.
• Through
  
  February 2021
  
  , AcelRx has achieved 387 formulary approvals.

2021 Guidance

The Company’s 2021 year-end goals include obtaining 615 cumulative formulary approvals as we expect COVID restrictions on elective surgeries to be loosened in the second half of 2021. Quarterly combined R&D and SG&A expense is expected to be approximately

$9

–

$10 million

(and

$8.0

–

$8.5 million

excluding stock compensation and depreciation). Annual debt service is expected to approximate

$10 million

as we continue to pay down amounts outstanding under our senior debt facility. Annual capital expenditures are expected to range from

$4

–

$5 million

attributed mainly to the final installation of our new high-volume, automated packaging line at our contract manufacturer. We expect initial packaging batches to be produced at the end of this year, with commercial batches beginning after regulatory approvals are received in Q3 2022. With a path now clear to final installation of the automated packaging line, we also plan to close on an agreement to out-license DZUVEO for

Europe

later this year.

2021 financial guidance is based on the Company’s current expectations and are forward-looking statements.  Actual results could differ materially depending on market conditions and the factors set forth under Forward-Looking Statements below.

About DSUVIA (sufentanil sublingual tablet), 30 mcg

DSUVIA®, known as DZUVEO™ in

Europe

, approved by the FDA in

November 2018

, 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. The European Commission approved DZUVEO for marketing in

Europe

in

June 2018

and AcelRx is currently in discussions with potential European marketing partners.

Non-GAAP Financial Measures

To supplement AcelRx’s financial results and guidance presented in accordance with U.S. generally accepted accounting principles (GAAP), AcelRx uses certain non-GAAP financial measures in this press release, in particular, excluding stock-based compensation expense from its operating expenses. AcelRx believes that these non-GAAP financial measures provide useful supplementary information to, and facilitate additional analysis by, investors and analysts. In particular, AcelRx believes that these non-GAAP financial measures, when considered together with AcelRx’s financial information prepared in accordance with GAAP, can enhance investors’ and analysts’ ability to meaningfully compare AcelRx’s results from period to period and to its forward-looking guidance. In addition, these types of non-GAAP financial measures are regularly used by investors and analysts to model and track AcelRx’s financial performance. AcelRx’s management also regularly uses these non-GAAP financial measures internally to understand, manage and evaluate AcelRx’s business and to make operating decisions. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read in conjunction with AcelRx’s consolidated financial statements prepared in accordance with GAAP. The non-GAAP financial measures in this press release and the accompanying tables have limits in their usefulness to investors and may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies.

Cautionary Statements

Tvetenstrand and Wolff Study.

The study compared a prospective group of patients with preoperative dosing of a single sublingual DSUVIA tablet to a historical control group receiving standard intravenous (IV) opioid administration for same-day general surgery procedures. A total of 127 patients were evaluated in the study. Study limitations include that it was an open-label study, the retrospective nature of the control group, and the focus on only general surgery patients. AcelRx did not provide funding for the conduct of the Tvetenstrand and Wolff Study but did fund medical writing support. Dr. Tvetenstrand is a paid consultant of AcelRx.

Cassavaugh Study.

The evaluation focused on 140 patients who were dosed with DSUVIA compared to 158 patients who had been dosed with traditional IV opioids during the same time period undergoing the same surgical procedures. Study limitations included that it was a single-center, retrospective study of DSUVIA dosing in a surgical patient population and both inpatient and outpatient surgery data was combined. The study did not control for whether patients were opiate naïve or opiate tolerant in the treatment groups, however, there is no reason for these patients to be present at a substantially higher frequency in either group. AcelRx did not provide funding for the conduct of the evaluation but did fund medical writing support. Dr. Cassavaugh is a paid consultant of AcelRx.
