ENDO PHARMACEUTICALS HOLDINGS INC. (Registrant) By: /s/ CAROL A. AMMON ---------------------------------- Name: Carol A. Ammon Title: Chairman & Chief Executive Officer Dated: August 1, 2002 INDEX TO EXHIBITS Exhibit No. Description 99.1 Press release issued by Endo Pharmaceuticals Holdings Inc. on August 1, 2002 Exhibit 99.1 [ENDO LOGO] For Immediate Release CONTACTS: Bill Newbould Endo Pharmaceuticals (610) 558-9800 Jeremy Fielding/Jon Morgan Kekst & Company (212) 521-4800 ENDO PHARMACEUTICALS ANNOUNCES TENTATIVE FDA APPROVAL OF ITS OXYCODONE EXTENDED-RELEASE PRODUCT CHADDS FORD, Pa., August 1, 2002 - Endo Pharmaceuticals Holdings Inc. (Nasdaq: ENDP; ENDPW), a market leader in pain management, announced today that the U.S. Food and Drug Administration (FDA) has granted tentative approval of Endo's abbreviated new drug application (ANDA) for Oxycodone Extended-Release Tablets, 10 mg, 20 mg, 40 mg and 80 mg. Endo's Oxycodone Extended-Release Tablets are AB-rated bioequivalent versions of the 10mg, 20mg, 40mg and 80mg strengths of OxyContin(R), a product of The Purdue Frederick Company that is indicated for the management of moderate-to-severe pain when a continuous, around-the-clock analgesic is needed for an extended period of time. These strengths had combined 2001 U.S. branded sales of approximately $1.5 billion. In accordance with the Waxman-Hatch Act, Endo made the required paragraph IV certification when it filed and amended an ANDA with the FDA for this product. Endo believes that once final FDA approval is granted, it will have 180 days of marketing exclusivity with respect to the 10 mg, 20 mg and 40 mg strengths of this product since it believes that it was the first company to file an ANDA containing a paragraph IV certification for these strengths. Since October 2000, Purdue Frederick has filed three lawsuits against Endo in response to its ANDA submission and related amendments alleging that Endo's Oxycodone Extended-Release product infringes three of its patents which cover the 10 mg, 20 mg, 40 mg and 80 mg strengths of OxyContin(R). These patent challenges are currently pending in the U.S. District Court for the Southern District of New York. Commenting on the tentative FDA approval, Carol A. Ammon, chairman and chief executive officer, said, "We are pleased with the FDA's decision, which reflects our ability to bring products successfully through the regulatory process." She noted that tentative approval such as this indicates that the FDA has made a determination that a generic product meets the substantive requirements for approval, subject to the expiration of all statutorily imposed non-approval periods. A final approval must be granted before Endo is permitted to market Oxycodone Extended-Release Tablets. About Endo Endo Pharmaceuticals is a fully integrated specialty pharmaceutical company with market leadership in pain management products.
