A.P. Pharma Receives Additional Patent for 5-FU Microsponge Formulation; Patent Covering Carac Formulation Extended to 2021
REDWOOD CITY, Calif.--(BUSINESS WIRE)--Sept. 17, 2003--A.P. Pharma, Inc. (Nasdaq:APPA) today announced that the Company has received a notice of allowance from the U.S. Patent and Trademark Office (USPTO) extending patent coverage to 2021 for the use of its Microsponge(R) delivery system in its formulation containing 5-fluorouracil. The Company receives royalties on this formulation from marketing partner Dermik Laboratories Inc., an Aventis company, on sales of Carac(TM) in the U.S. for the life of the patents.
Carac is a once-a-day topical prescription product for the treatment of actinic keratoses (AK), a common precancerous skin condition caused by over-exposure to the sun. The product has a number of advantages over existing topical therapies, including less irritation with shorter duration of therapy and reduced dosage frequency. Since its launch in April 2001, Carac has captured approximately 25% of the U.S. topical market for AK.
In 1999 the Company received a notice of allowance from the USPTO extending patent coverage to 2016 for use of its Microsponge technology with tretinoin, which is marketed as Retin-A Micro(R) by Ortho Neutrogena, a Johnson & Johnson company. Retin-A Micro is a leading prescription treatment for mild to moderate acne. Retin-A Micro was launched in the U.S. in 1997 and in Canada in 2001. A lower dose formulation of Retin-A Micro was introduced in the U.S. in 2002 after receiving U.S. marketing approval.
A.P. Pharma's royalty income last year totaled more than $4 million and to date this year has grown by 18%. This additional patent now extends royalty income from Carac sales to 2021. Combined with patents on Retin-A Micro, which last until 2016, A.P. Pharma's royalty income from these two product lines is expected to continue to grow both through increased U.S. sales and introductions in additional markets. Royalty income is key in the Company's strategy to support product development programs incorporating its site-specific Biochronomer(TM) drug delivery systems.
