(OTCBB: APPA.OB), a specialty pharmaceutical company, today reported financial results for the quarter ended June 30, 2012 and highlighted recent corporate progress.

“With the recent closing of our common stock offering, we are in a strong financial position as we approach the commercialization phase with our lead product candidate, APF530, for the prevention of both acute- and delayed-onset chemotherapy-induced nausea and vomiting,” said John B. Whelan, A.P. Pharma's president and chief executive officer. “As previously announced, we successfully completed our thorough QT and metabolism studies required for our APF530 New Drug Application resubmission. We now also have successfully completed our non-clinical human factors validation study. We remain on track to resubmit our New Drug Application for APF530 to the U.S. Food and Drug Administration in September 2012.”

A.P. Pharma’s net loss for the second quarter of 2012 was $4.6 million, or $0.02 per share, compared to a net loss of $1.9 million, or $0.05 per share, for the second quarter of 2011. The net loss was higher in the current fiscal quarter primarily due to increased spending related to the planned NDA resubmission and higher personnel-related expenses, including stock compensation expense. The prior-year quarter included contract revenue from an agreement with Merial Limited, which was terminated in May 2011.

Cash and cash equivalents as of June 30, 2012 were $12.4 million, compared to $18.0 million at December 31, 2011. Net cash used in operating activities was $8.1 million for the six months ended June 30, 2012. In May 2012, the Company received $3.0 million in cash proceeds from the issuance of convertible notes resulting from note holders’ exercise of purchase rights associated with the $4.5 million private placement financing announced in April 2011.

In July 2012, the Company completed a private placement of common shares resulting in $50.7 million of net proceeds. The Company believes that its current cash resources are sufficient to fund its operations through the anticipated product launch of APF530 in 2013.

A.P. Pharma's lead product candidate, APF530, is being developed for the prevention of both acute- and delayed-onset chemotherapy-induced nausea and vomiting (CINV). One of the most debilitating side effects of cancer chemotherapy, CINV is a leading cause of premature discontinuation of treatment. There is only one injectable 5-HT3 antagonist approved for the prevention of delayed-onset CINV, so this indication represents an area of particular unmet medical need. APF530 contains the 5-HT3 antagonist granisetron formulated in the Company’s proprietary Biochronomer™ drug delivery system, which allows therapeutic drug levels to be maintained for five days with a single subcutaneous injection. This five-day range is designed to cover the delayed phase of CINV, whereas currently available intravenous and oral formulations of granisetron are approved only for the prevention of acute-onset CINV. Granisetron was selected for APF530 because it is widely prescribed by physicians based on a well-established record of safety and efficacy.

A.P. Pharma is a specialty pharmaceutical company developing products using its proprietary Biochronomer™ polymer-based drug delivery platform. This drug delivery platform is designed to improve the therapeutic profile of injectable pharmaceuticals by converting them from products that must be injected once or twice per day to products that need to be injected only once every one or two weeks. The Company’s lead product candidate, APF530, is being developed for the prevention of both acute- and delayed-onset chemotherapy-induced nausea and vomiting. A.P. Pharma received a Complete Response Letter to its APF530 New Drug Application (NDA) and is targeting a resubmission of the NDA to the U.S. Food and Drug Administration in September 2012.
