About T-3811

Originating to Toyama Chemical, T-3811 is a new-type quinolone synthetic antibacterial agent, previously licensed out to the US firm Bristol-Myers Squibb. Bristol-Myers Squibb had conducted the clinical trials on a worldwide basis, from which T-3811 is expected to contribute to therapy in the wide range of field including respiratory and surgical infection. Toyama Chemical reacquired all rights pertaining to T-3811 from Bristol-Myers Squibb in October 2003, due to Bristol-Myers Squibb's commercial strategy reasons. As was press-released, the Letter of Intent with Schering-Plough was made on March 31, 2004, establishing the basic framework of this license agreement. Since then, both parties have been discussing the terms of the definitive licensing agreement, and the parties have been able to conclude this agreement as originally scheduled.

As Schering-Plough indicated when the letter of intent was announced, the company expects the addition of garenoxacin to broaden the anti-infective portfolio it is developing. Schering-Plough said this is in line with its strategy to build strength in its global franchises through internal research and external licensing opportunities.

Katsuhiko Nakano, president and CEO of Toyama Chemical stated "We are very glad to conclude the license agreement on garenoxacin with Schering-Plough. Through our collaboration with Schering-Plough, we look forward to bringing garenoxacin, the novel antibacterial compound, to the market and contributing to the advance of anti-infective therapy worldwide." He added, "With this collaboration, we would like to establish a good relationship with Schering-Plough. We see this as being important as we gain experience to undertake other similar collaborations in the future."

Toyama Chemical Co., Ltd. constantly strives to supply the world with innovative treatment methods for infectious diseases. In collaboration with Schering-Plough Corporation, Toyama Chemical aims to achieve early approval and rapid growth for T-3811 overseas and in Japan.
