News Release

REDWOOD CITY, Calif., March 7, 2019 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), (AcelRx), a specialty pharmaceutical company focused on innovative therapies for use in medically supervised settings, today provided a business update and reported its fourth quarter and full year 2018 financial results.

"This past year was a tremendous success for the Company, highlighted by the FDA approval of DSUVIA in the U.S., followed by our staged launch last month," said Vince Angotti, Chief Executive Officer of AcelRx.  "Our recent efforts with the wholesalers and GPOs have laid the foundation for DSUVIA's use in certified medically supervised healthcare settings. While the launch is only one month old, we are pleased with the initial response by healthcare professionals to DSUVIA as an effective and efficient new option for the management of acute pain in these settings," continued Angotti.

Fourth Quarter and Recent Highlights

• Following the positive recommendation from the FDA advisory committee in October 2018, the FDA approved DSUVIA in November 2018 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.
• AcelRx now has 14 Orange Book listed patents with exclusivity dates ranging from 2027 through 2031.
• The staged DSUVIA launch was initiated with fifteen hospital account managers hired, trained and placed in the field beginning in second half of January 2019.
• Commercial launch of DSUVIA with initial contracted wholesaler orders received and shipped in the second half of February, as planned.
• Contracts executed with GPO targets covering approximately 80% of the hospital customers included in the DSUVIA initial launch markets.

Financial Information

• Cash, cash equivalents and short-term investments balance of $105.7 million as of December 31, 2018; 
• Combined R&D and G&A expenses for the fourth quarter 2018 totaled $10.4 million compared to $7.6 million for the prior year period. Excluding stock-based compensation expense, these amounts were $9.2 million for the fourth quarter of 2018 compared to $6.6 million for the prior year period. The increase in R&D and G&A expenses is primarily due to increased personnel-related expenses in preparation for the commercial launch of DSUVIA. R&D and G&A expenses for the year ended December 31, 2018 totaled $33.9 million compared to $36.0 million in the year ended December 31, 2017. Excluding stock-based compensation expense, these amounts were $29.1 million for 2018 compared to $32.0 million for the prior year. The decrease in R&D and G&A expenses is primarily due to lower Zalviso-related expenses attributed to the Phase 3 clinical program completed in 2017, partially offset by increased personnel-related expenses in preparation for the commercial launch of DSUVIA. See the "Reconciliation of Non-GAAP Financial Measures" table below for a reconciliation of the non-GAAP operating expenses described above to their related GAAP measures;
• Excluding $53.4 million in net proceeds raised from the issuance of equity, the Company used $11.3 million in cash, including $2.3 million in debt service, during the quarter ended December 31, 2018; and
• For the fourth quarter of 2018, net loss was $12.6 million, or $0.18 per basic and diluted share, compared to $9.9 million, or $0.20 per basic and diluted share, for the fourth quarter of 2017.  Net loss for the year ended December 31, 2018 was $47.1 million, or $0.81 basic and diluted net loss per share, compared to $51.5 million, or $1.10 basic and diluted net loss per share, for the prior year.

2019 Guidance
Based on the initial month of experience in the field with its commercial team, the Company is increasing its expected number of formulary approval wins by the end of 2019 to 125, up from the previous guidance of 100.  In addition, the Company plans to accelerate the hiring of the next stage of 25 hospital account managers to the third quarter from the fourth quarter to better cover the initial indications of interest in DSUVIA by hospitals.  Quarterly combined R&D and SG&A expense in 2019 is expected to range from $15 million to $18 million, depending on the quarter, which includes approximately $2 million of non-cash stock-based compensation per quarter.  Annual debt service is expected to approximate $9 million.  Annual capital expenditures are expected to range from $5-$7 million attributed mainly to the installation of a new high-volume, automated packaging line at our contract manufacturer.

2019 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 "Safe Harbor Statement" below.

About DSUVIA (sufentanil sublingual tablet), 30 mcg
DSUVIA™, known as DZUVEO™ outside the United States, approved by the FDA in November 2018, is indicated for use in adults in a certified medically supervised healthcare setting, such as hospitals, surgical centers, and emergency departments, for the management of acute pain in adult patients 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 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 currently marketed for intravenous (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 Medicines Agency (EMA) approved DZUVEO for marketing in Europe in June 2018 and the Company is currently in discussions with potential European marketing partners.
