A.P. Pharma Completes Financing for up to $30 Million; Sells Royalty Rights to Retin-A Micro and Carac; Transaction is Non-Dilutive to Shareholders

01/18/2006 |

REDWOOD CITY, Calif., Jan 18, 2006 (BUSINESS WIRE) -- A.P. Pharma, Inc. (NASDAQ:APPA) today announced that it has sold rights to future royalties on sales of Retin-A Micro(R) and Carac(R) to an affiliate of the Paul Royalty Fund ("Paul Royalty") for up to $30 million.

Proceeds of $25 million were received upon the closing of this transaction and will be used primarily to fund pivotal clinical development of APF530, A.P. Pharma's drug candidate for the prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV). The remaining $5 million will be paid based on the satisfaction of certain predetermined milestones over the next four years.

"This financing is non-dilutive to our shareholders and generates considerable cash to fund pivotal clinical trials with APF530. APF530 has demonstrated very promising data in a Phase 2 trial and potentially has significant advantages over the currently available therapy for the prevention of acute and delayed CINV, approximately a $1 billion annual market in the U.S. While our strategy remains to secure a corporate partner for APF530, these funds will allow us to continue development of the product and to negotiate from a position of strength in seeking favorable partnership terms," said Michael O'Connell, A.P. Pharma's President and Chief Executive Officer.

"Retin-A Micro and Carac demonstrate our ability to develop commercially successful products. The sale of these future royalties to Paul Royalty supports the development of our higher-value pharmaceutical products based on our proprietary Biochronomer(TM) bioerodible polymer delivery systems, having moved our focus away from the Microsponge(R) system-based topical dermatology business," he added.

A.P. Pharma is entitled to receive royalties on the sales of Retin-A Micro(R) and Carac(R) based on the terms of its license agreements with Ortho Neutrogena (formerly Ortho Dermatological), a member of the Johnson & Johnson family of companies, and Dermik Laboratories, a Sanofi-Aventis company, respectively.

"We're pleased to provide A.P. Pharma with a non-dilutive source of capital. This type of transaction represents an alternative source of growth capital for companies and we believe that this form of financing will not only be increasingly sought after but that Paul Royalty will continue to be the leading provider of capital in this sector," said Clarke B. Futch, Partner, Paul Royalty Fund.

About APF530

APF530, which contains the anti-nausea drug granisetron formulated with the Company's proprietary Biochronomer(TM) bioerodible drug delivery system, is being developed for the prevention of both acute and delayed CINV. As reported, the Phase 2 study was completed in September 2005 in patients undergoing moderately and highly emetogenic chemotherapy for cancer. The primary endpoints, which included an evaluation of safety, tolerability and pharmacokinetics, were successfully met. In addition, efficacy endpoints were evaluated relating to emetic events and the use of rescue medication in patients receiving either highly or moderately emetic chemotherapy regimens.

There were no serious adverse events attributed to the APF530 formulation, and injections of APF530 were well tolerated. The pharmacokinetic evaluation of granisetron in all three dose groups clearly indicated that measurable plasma levels of granisetron were evident over a seven day period.

Analysis of the open label efficacy data from the Phase 2 patient groups receiving either moderately or highly emetogenic chemotherapy indicated that the percentage of complete responders in the moderately emetogenic group was 90% in the acute phase and 78% in the delayed phase. In the group receiving highly emetogenic chemotherapy, the percentage of complete responders was 81% in the acute phase and 80% in the delayed phase. "Complete response" was defined as no emetic episodes and no use of rescue medication.

Based on the data generated from the Phase 2 study, two dose levels of APF530 have been selected and preparations are well underway to initiate Phase 3 clinical trials.
