FDA Grants Tentative Approval to First Generic Challenger to Procardia XL(R) Using Penwest's TIMERx(R) Technology - Marks First Drug Containing Penwest's Technology to Receive Tentative Approval in The United States - PATTERSON, N.Y., March 19 /PRNewswire/ -- Penwest Pharmaceuticals Co. (Nasdaq: PPCO) announced today that the Food and Drug Administration (FDA) gave Mylan Pharmaceuticals, a division of Mylan Laboratories (NYSE: MYL), a tentative approval to an AB-rated generic version of Pfizer's Procardia XL(R) (nifedipine), one of the largest selling drugs for hypertension and angina. The generic drug, approved for a 30 mg dose, is a joint effort of Penwest and Mylan. Penwest and Mylan developed the product using Penwest's proprietary TIMERx controlled release drug delivery technology. Mylan will handle production, distribution and marketing of the new drug. The designation by the FDA as AB-rated, a certification of bioequivalence, will allow pharmacies to substitute this generic version when a physician prescribes Procardia XL. Reacting to the FDA decision, Penwest said today that Mylan's nifedipine formulation which utilizes TIMERx controlled release technology had passed stringent FDA bioequivalence guidelines. Mylan's generic nifedipine controlled release tablet using Penwest's proprietary drug delivery technology has undergone extensive testing to meet FDA guidelines. "We are pleased that the FDA has given its tentative approval to a product containing TIMERx," said Tod Hamachek, Chairman and Chief Executive Officer of Penwest. "This generic form is as safe and effective as Procardia XL and will offer a lower cost alternative to patients." The application has now been cleared from a regulatory perspective, but final approval will not be granted until certain legal issues, including the patent lawsuit brought by Bayer and Pfizer against Mylan, have been resolved. Penwest began working with Mylan in 1994 on a generic version of Procardia XL. In May 1997, Mylan became the first company to file an ANDA (abbreviated new drug application) for a generic nifedipine version of the 30 mg strength of Procardia XL. Mylan's filing was significant for Penwest because it was the first regulatory filing in the United States for a product incorporating TIMERx technology. Since Mylan was the first to file with the FDA and to certify the invalidity and non-infringement of a listed patent, Penwest expects that the 30mg product will have a minimum of 180 days of generic market exclusivity after final approval by the FDA. Hamachek added "This FDA approval marks the third drug utilizing our TIMERx technology to receive international regulatory clearance, following approvals in the last year of nifedipine in the United Kingdom and oxybutynin in Finland, Austria, Ireland and the Netherlands. The TIMERx technology is highly adaptable to a variety of different oral drugs, including both soluble and insoluble. The TIMERx system is currently being utilized in several other drug development initiatives worldwide." Penwest Pharmaceuticals Co. is engaged in the research, development and commercialization of novel drug delivery technologies. Based on its experience in developing and manufacturing tabletting ingredients for the pharmaceutical industry, the Company has developed its proprietary TIMERx controlled release drug delivery technology, which is applicable to a broad range of orally administered drugs. The Company is also an established manufacturer and distributor of excipients, the inactive ingredients used in binding, disintegrating and lubricating tabletted pharmaceutical and nutritional products. TIMERx is an innovative, patented oral drug delivery technology developed by Penwest. Currently, there are 55 TIMERx patents pending worldwide and there are 19 patents issued in the United States, two in Europe and three in Japan. Controlled release systems such as TIMERx offer many distinct advantages over immediate dose compounds including possible reduction of side effects and a more favorable release profile. Additionally, the Company believes that the TIMERx technology is particularly beneficial for the development of controlled release products because of its superior performance characteristics and ability to run on conventional tabletting equipment.

For this purpose, any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words, "believes," "anticipates," "plans," expects," and similar expressions are intended to identify forward-looking statements. Such risks and uncertainties include the risk that the patent lawsuit brought by Bayer and Pfizer against Mylan will result in an unfavorable outcome for the Company or will be protracted, regulatory risks relating to the drug, actual and potential competition, the risk of additional patent litigation, the timing and outcome of regulatory approval of products, dependence on collaborators and other risks as set forth under the caption "Risk Factors" in the Company's Registration Statement on Form 10, which is on file with the Securities and Exchange Commission which risk factors are incorporated by reference.
