A.P. Pharma, Inc. (OTCQB:APPA.PK), a specialty pharmaceutical company, today announced that it has entered into definitive agreements with certain new and existing accredited investors providing for a private placement of common stock and warrants in which the Company will receive $24 million in gross proceeds. The common stock and warrants are being sold in units at a price of $0.15 per unit. Each unit consists of one share of common stock and one warrant to purchase 0.5 additional shares of common stock at a price of $0.18 per share. The transaction is expected to close on or about July 1, 2011, subject to customary closing conditions.

The Company expects the proceeds from this offering, combined with its current cash resources, to fund its operations into 2013.

“We believe that this financing will provide the resources necessary to perform the activities needed to resubmit our New Drug Application (NDA) for APF530 in the first half of 2012 and to fund our operations beyond the expected U.S. Food and Drug Administration action date for APF530 in the second half of 2012,” stated John Whelan, A.P. Pharma’s president and chief executive officer. “We remain committed to obtaining regulatory approval of APF530, which we believe will provide physicians and cancer patients with an important option for the prevention of chemotherapy-induced nausea and vomiting, a terrible morbidity associated with cancer treatment.”

MTS Securities, LLC acted as sole placement agent in the Offering.

About APF530

A.P. Pharma’s lead product, APF530, is in development for the prevention of both acute-onset and delayed-onset chemotherapy-induced nausea and vomiting (CINV). 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. Intravenous and oral formulations containing granisetron are approved for the prevention of acute-onset CINV, but not delayed-onset CINV. Granisetron was selected because it is widely prescribed by physicians based on a well-established record of safety and efficacy.
