07/23/2001 |
REDWOOD CITY, Calif., Jul 23, 2001 (BW Health Wire) -- A.P. Pharma, Inc. (Nasdaq:APPA), a specialty pharmaceutical company, today announced that Canadian drug regulatory authorities have granted marketing clearance for Retin-A Micro(R) (tretinoin gel) microsphere, 0.1% for the treatment of acne.

This topical medication was launched in the U.S. in 1997, becoming the first ethical pharmaceutical to contain the patented Microsponge(R) delivery systems. Retin-A Micro is one of the leading products in the $500 million-per-year U.S. prescription acne market and is licensed to A.P. Pharma's development and marketing partner, Ortho Dermatological, a member of the Johnson & Johnson family of companies. Johnson & Johnson Canada will market the product in Canada under the same U.S. trade name, Retin-A Micro. Upon commercialization, anticipated in the third quarter of 2001, A.P. Pharma will begin to receive royalties on product sales.

"Retin-A Micro has proven to be extremely popular in the U.S. and we anticipate that it will enjoy similar success in Canada. Sales of Retin-A Micro in Canada will add to our existing royalty streams and we look forward to benefiting from product line extensions and continued geographic expansion by Johnson & Johnson," commented Mike O'Connell, A.P. Pharma's president and chief executive officer.

Using its existing cash resources and growing royalty streams, A.P. Pharma intends to develop and commercialize its families of bioerodible delivery systems for injectable and implantable drug delivery. Known as Biochronomer(TM) systems, they are designed for the controlled release of drugs into various sites such as under the skin, in muscle or in the peritoneal cavity and offer potential for use in a broad array of pharmaceutical products.
