Antares Pharma, Inc. (NASDAQ: ATRS) today reported operating and financial results for the first quarter ended March 31, 2013.

Paul K. Wotton, Ph.D., President and Chief Executive Officer, stated, “The FDA’s acceptance of the OTREXUP™ new drug application during the first quarter represents one more important milestone as we transition to a product focused Specialty Pharmaceutical Company. We are working closely with the FDA on the OTREXUP™ NDA file and look forward to meeting the PDUFA target date.” Dr. Wotton continued, “While we work through the review process with the FDA, the commercial team has validated the market potential for OTREXUP™. Independent research indicates there is a clear value proposition in the optimization of methotrexate through subcutaneous self-administration for both patients and third-party payers. Therefore, we believe that OTREXUP™ could expand physician treatment options for patients with rheumatoid arthritis and or psoriasis.”

Total revenues were $4.5 million and $6.9 million for the three months ended March 31, 2013 and 2012, respectively. In the three months ended March 31, 2012, the Company recognized revenue of approximately $3.0 million in connection with one-time milestone payments for our 3% oxybutynin gel from Actavis and Daewoong Pharma.

Product sales were $2.5 million for both the three months ended March 31, 2013 and 2012. Product sales in the first quarter of 2013 included $0.6 million of initial sales to Teva of pre-launch quantities of our VIBEX™ auto injector for Teva’s generic epinephrine auto injector product. Product sales in the first quarters of 2013 and 2012 included $0.5 million and $0.8 million, respectively, of sales of our topical oxybutynin gel 3% product to Actavis in connection with their marketing of Gelnique 3%, which was launched in April 2012. The balance of our product sales in each period were primarily sales of reusable needle-free injector devices and disposable components to Teva and Ferring.

Development revenues were $0.8 million and $3.0 million for the three months ended March 31, 2013 and 2012, respectively. The development revenue in the first quarter of 2013 was primarily due to auto injector and pen injector development work for Teva while the development revenue in the first quarter of 2012 was primarily due to a non-recurring FDA approval milestone payment of $2.5 million recognized in connection with our Gelnique license agreement with Actavis.

Licensing revenue was $0.1 million and $0.6 million for the three months ended March 31, 2013 and 2012, respectively. The licensing revenue in the first quarter of 2013 was primarily due to recognition of revenue deferred in prior years under agreements with Ferring. Licensing revenue in the first quarter of 2012 was primarily due to an upfront fee received in connection with our licensing agreement with Daewoong Pharma.

Revenue from royalties was $1.2 million and $0.8 million for the three months ended March 31, 2013 and 2012, respectively. The majority of the royalty revenue in each period consisted of royalties received from Teva on sales of their hGH Tev-Tropin. The increase in royalty revenue was primarily due to royalties received from Actavis on sales of Gelnique in the first quarter of 2013. No royalties were received in the first quarter of 2012 from Actavis as Gelnique 3% was launched in April 2012.

Total gross profit decreased in the first quarter of 2013 to $2.5 million from $4.9 million in 2012. The decrease in the quarter was primarily due to a milestone payment from Actavis that was recognized as development revenue in the first quarter of 2012.

Total operating expenses were approximately $5.9 million and $5.0 million for the first quarters of 2013 and 2012, respectively. The increase was primarily due to an increase in OTREXUP™ commercialization and marketing activities in anticipation of a 2014 launch.

Net loss was approximately $3.4 million and $0.1 million for the first quarters of 2013 and 2012, respectively, and net loss per share was $0.03 and $0.00 in the first quarters of 2013 and 2012, respectively.

At March 31, 2013, Antares had approximately $80.3 million in cash and investments, compared to approximately $85.2 million at December 31, 2012.
