Teva Comments on Mylan Paragraph IV Filing for COPAXONE[R]; Files Lawsuit against Generic Filer for Patent Infringement.

Market-Leading Multiple Sclerosis Therapy Presents Significant Legal, Regulatory and Technical Challenges for Generic Filers

JERUSALEM -- Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) commented today on the abbreviated new drug application (ANDA) containing a Paragraph IV certification for COPAXONE([R]) (glatiramer acetate injection), filed by Mylan Pharmaceuticals Inc. Teva also announced that it has filed a lawsuit against Mylan Pharmaceuticals, Inc., Mylan Inc. and Natco Pharma Ltd. for patent infringement in the U.S. District Court for the Southern District of New York.

Mylan's filing of a purported generic version of COPAXONE([R]) was not unexpected, as the company announced its intention over a year ago. Teva received Mylan's Paragraph IV certification notice referring to Teva's U.S. Patents, which cover the chemical composition of COPAXONE([R]), pharmaceutical compositions containing it, and methods of using it. These patents are listed in the U.S. Food and Drug Administration's (FDA) Orange Book and extend through May 24, 2014.

Teva remains committed to vigorously defending its COPAXONE([R]) intellectual property rights against infringement wherever they are challenged and intends to pursue all relevant regulatory avenues via the FDA. Teva's lawsuit has been filed within the 45-day period provided under the Hatch-Waxman legislation. The lawsuit triggers a stay of FDA approval for the Mylan ANDA until the earlier of the expiration of a period of 30 months and a district court decision in its favor, and is also subject to the expiration of any exclusivity rights that may attach to earlier filed ANDAs.

COPAXONE([R]) is a highly-complicated product to develop and manufacture, and given the inability to fully characterize the active ingredients of COPAXONE([R]), Teva has serious doubts about any generic applicant's ability to demonstrate conclusively that the composition of its product is identical to that of COPAXONE([R]).

Teva contends that any company that files an application for any glatiramoid substance, via an ANDA or 505(b)(2) application, should conduct full-scale, placebo-controlled clinical trials with measured clinical endpoints in MS patients to establish safety, efficacy and immunogenicity in this patient population. Internal research at Teva has indicated that even minor changes in the synthetic process and/or molecular weight distribution of a glatiramoid can have severe ramifications on the safety and mechanism of action of the product.

In July 2008, Teva received a Paragraph IV certification notice from first-to-file Momenta Pharmaceuticals, Inc./Sandoz Inc. relating to their ANDA containing a Paragraph IV certification for COPAXONE([R]). On August 28, 2008, Teva filed a lawsuit in the U.S. District Court for the Southern District of New York with respect to Momenta's filing. A trial date has not been set.
