AcelRx reports revenue of $408,000 for third quarter 2011

AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), ("AcelRx"), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute and breakthrough pain, reported financial results today for the third quarter and nine months ended September 30, 2011.

Net loss for the third quarter of 2011 was $5.8 million, or $0.30 per share, compared with a net loss of $3.6 million, or $5.38 per share, for the third quarter of 2010.  Common shares used in calculating basic and diluted earnings per share were 19,459,000 in the third quarter of 2011 compared to 669,000 common shares in the third quarter of 2010.

During the third quarter of 2011, AcelRx recognized revenue of $408,000 resulting from reimbursement for work completed under a research grant from the US Army Medical Research and Material Command, or USAMRMC, for development of its ARX-04 product candidate.  Research and development expenses for the three months ended September 30, 2011 totaled $3.9 million, compared with $1.5 million for the three months ended September 30, 2010.  The increase was primarily due to development expenses for ARX-01 as AcelRx prepared for planned Phase 3 trials.  General and administrative expenses were $1.9 million for the quarter ended September 30, 2011, compared with $1.1 million for the quarter ended September 30, 2010. The increase results primarily from expenses associated with operation as a public company.

For the nine months ended September 30, 2011, AcelRx reported a net loss of $13.7 million, or $0.83 per share, compared with a net loss of $10.8 million, or $16.63 per share for the same period in 2010.  Common shares used in calculating basic and diluted earnings per share were 16,594,000 for the nine months ended September 30, 2011 compared to 651,000 common shares for the same period in the prior year.

As of September 30, 2011, AcelRx had cash, cash equivalents and investments of $32.0 million, compared with $37.8 million as of June 30, 2011 and $3.7 million as of December 31, 2010.  In February 2011, AcelRx completed its initial public offering, resulting in net proceeds to AcelRx of $34.9 million.  In June 2011, AcelRx entered into a $20.0 million secured loan agreement with Hercules Technology Growth Capital, or Hercules.  Upon execution of the agreement, AcelRx received $10.0 million in the first tranche of the loan, $2.8M of which was used to pay down existing debt.

"During the third quarter of 2011, we continued to move towards initiation of our Phase 3 studies for ARX-01, our lead product candidate for acute post-operative pain, and also towards initiation of a Phase 2 study for ARX-04, our product candidate for moderate-to-severe acute pain," said Richard King, President and CEO of AcelRx.  "We have made progress on the ARX-01 device related activities that must be completed prior to initiation of Phase 3 clinical studies.  We anticipate feedback from FDA on the submitted software verification and validation protocols, and a device reprocessing protocol, and currently expect that we will be in a position to dose the first patient in the Phase 3 clinical program in late 2011 or early 2012, with an expectation to complete all Phase 3 clinical studies by the end of 2012," said Mr. King.

Development Updates

• The contract research organization, or CRO, PharmaNet, has been engaged to conduct the first two ARX-01 Phase 3 studies.  Clinical sites have been engaged for the abdominal surgery study and a majority of the sites for the head-to-head comparator study have been identified.  
• We recently received correspondence from the FDA stating that a final planned Human Factor study, though required for final product approval, is not a prerequisite to initiating ARX-01 Phase 3 studies.  There are, however, three additional device assessments focused on software verification, software validation and device reprocessing, originally planned as precursors to, or associated with, the final Human Factor Study, which remain as requirements from FDA prior to the start of Phase 3.  Protocols for these assessments have been submitted to the FDA for review, and we await the agency's feedback.  We plan to conduct the software verification and validation and device reprocessing studies prior to initiation of the Phase 3 clinical program. We currently expect that we will be in a position to dose the first patient in a Phase 3 placebo-controlled post-operative pain study following major abdominal surgery in late 2011 or early 2012. The remaining Phase 3 studies, an active comparator study comparing the sufentanil NanoTab PCA System to intravenous morphine patient-controlled analgesia in post-operative patients, and a placebo-controlled study in patients after major orthopedic surgery, are expected to be initiated and completed in 2012. We plan to complete the final Human Factor study alongside the Phase 3 clinical program.    
• The NanoTab commercial manufacturing facility at AcelRx's contract manufacturer, Patheon, Inc., has been built, tested and qualified as a Good Manufacturing Practices, or GMP, facility. AcelRx will manufacture clinical and commercial supplies at this facility.
• In early October 2011, AcelRx filed an Investigational New Drug application for ARX-04, its product candidate for management of moderate-to-severe acute pain, with the FDA, and plans to initiate the Phase 2 study later this year with top line results available in the first half of 2012.  AcelRx has retained a CRO to conduct the Phase 2 ARX-04 study and the clinical sites for this study have been selected and retained.

Financial Outlook

AcelRx anticipates that research and development expenses will increase over the next several quarters as it seeks to complete Phase 3 development of ARX-01. The development of ARX-02, a product candidate for the treatment of cancer breakthrough pain, and ARX-03, a product candidate for mild sedation and pain relief in procedures conducted in a physician's office, will not advance until additional funding or the identification of a partner to support these efforts is secured. The development of ARX-04 beyond Phase 2 and initial preparations for Phase 3 is dependent on the identification of sources of additional funding or the identification of a partner to support these efforts.  Additionally, AcelRx anticipates increases in general and administrative expenses due to costs associated with operating as a public company and expansion of its corporate infrastructure to support ongoing development of its product candidates.

AcelRx believes its current cash, cash equivalents and investments, including the drawing, at AcelRx's option, of the second $10.0 million tranche pursuant to the $20.0 million Hercules loan facility are sufficient to fund operations into the first quarter of 2013.
