Takeda Wins Patent Infringement Litigation
against ANDA Filers for Generic ACTOS®

Osaka, Japan and Lincolnshire, III. - Takeda Pharmaceutical Company Limited ("Takeda") and its wholly owned subsidiary, Takeda armaceuticals North America, Inc. ("TPNA") announced today that Takeda's intellectual property rights have been successfully asserted against generic manufacturers seeking to challenge Takeda's patent rights to ACTOS (pioglitazone HCl). A federal judge of the U.S. District Court for the Southern District of New York ruled on February 21, 2006, that a patent covering the active ingredient of ACTOS is valid and enforceable.

Takeda filed patent infringement actions against Mylan harmaceuticals*1, Ranbaxy Laboratories*2, and Watson Pharmaceuticals*3, in October 2003, and against Alphapharm Pty*4 in March 2004, in response to the filing of Abbreviated New Drug Applications (ANDAs) with the FDA under provisions of the Hatch-Waxman Act, challenging certain of Takeda's listed patents, including U.S. Patent No. 4,687,777 (the "'777 patent"), which covers the active ingredient of ACTOS. Alphapharm and Mylan were the only defendants to challenge the '777 patent. Trial of the challenges by Alphapharm and Mylan to the validity and enforceability of the '777 patent took place from January 17, 2006 to January 30, 2006.

The Court's ruling prevents the FDA from approving the ANDAs filed by Alphapharm and Mylan, and thus prevents those generic manufacturers from selling pioglitazone tablets until the '777 patent expires, in 2011. Other U.S. patents covering certain methods of treatment using ACTOS and certain compositions that include ACTOS will expire in 2016.

"Takeda has confidence in its patents," said Mr. Seiji Hakoda, General Manager of Intellectual Property Dept. of Takeda. "Because innovation is critical to our company, we have a profound respect for the protection of intellectual property rights. We are pleased with the ruling."
