News Release Details

REDWOOD CITY, Calif.--(BUSINESS WIRE)--Aug. 4, 2003--A.P. Pharma, Inc. (Nasdaq:APPA), a specialty pharmaceutical company, today reported financial results for the three months ended June 30, 2003, reflecting increased royalty income and contract revenues as well as higher research and development expenses as the Company prepares to initiate a Phase II clinical trial with APF112.

Current Highlights

• Second quarter royalty income increased 11% to $1,031,000.
• Extensive Biochronomer(R) and APF112 safety studies completed.
• APF112 Phase II clinical study protocol and preclinical safety package submitted to the FDA.
• Inguinal hernia Phase II study planned to be initiated in 3Q 2003; clinical sites selected.
• Feasibility studies continue in the areas of ophthalmology, coatings and DNA; new studies being initiated.
• Cash, cash equivalents and short-term investments were $12.1 million at June 30, 2003, compared with $14.1 million at December 31, 2002.

Second Quarter Financial Results

A.P. Pharma reported that total revenues for the second quarter of 2003 increased 15% to $1,117,000, compared with $968,000 for the second quarter of 2002, primarily due to a continuing increase in royalty income from Retin-A Micro(R) marketed by Neutrogena, a Johnson and Johnson company. Total revenues also included an increase in contract revenues for research and development work performed in connection with feasibility studies.

Research and development expense for the second quarter of 2003 increased to $2,335,000 from $1,872,000 for the second quarter of 2002. This increase was due mainly to the cost of Biochronomer studies which were designed to demonstrate the biocompatibility of the polymer, and APF112 preclinical safety studies using the enhanced APF112 formulation for the treatment of post-surgical pain as part of a plan agreed in discussions with the U.S. Food and Drug Administration (FDA). In addition, costs associated with the manufacture of GMP product for human clinical trials were incurred. A comprehensive Phase II clinical package has been submitted to the FDA for review and the Company plans to initiate human clinical trials in inguinal hernia patients during the third quarter of 2003. The Company is also planning to file an IND for a second product candidate early in 2004.

The net loss for the second quarter of 2003 was $1,960,000, or $0.10 per share, compared with a net loss for the second quarter of 2002 of $1,493,000, or $0.07 per share.
