Taiho Pharmaceutical Co., Ltd. (HQ: Tokyo, President: Masayuki Kobayashi), the developer of the first orally available fluorouracil (FU) Chemotherapeutic treatment (TS-1/S-1), is presenting early stage data for eight novel oncology compounds, including potential first-in-class therapies. The data being presented during the from November 6 – 9, 2012 in Dublin, Ireland underscore Taiho’s steadfast commitment to improving cornerstone anti-metabolic cancer agents and developing novel molecular targeted therapies that can be used alone or in combination worldwide.

“The data being presented demonstrate Taiho’s ability to develop novel molecular targeted agents as well as next generation cytotoxic therapies, and underscore our continued commitment to developing investigational anticancer drugs that have the potential to improve treatment options available to cancer patients,” said Masayuki Kobayashi, Taiho Pharmaceutical’s president. “Our strategy surrounding innovative research and clinical development reinforces Taiho’s pursuit of becoming a top-ten oncology company in the next decade.”

Taiho established a foundation of innovative product development 50 years ago, and the Company is committed to achieving efficiencies to effectively yield rapid results. This commitment is best demonstrated by the recent movement of the TAS-102 antitumor agent through preclinical and clinical development. Preclinical results being presented at the EORTC-NCI-AACR Symposium show that TAS-102 exhibited marked tumor growth delay after drug treatment due to FTD incorporation into DNA when evaluated using a well-recognized animal model for breast cancer, and a survival benefit in a colon cancer model.

A Phase II study of TAS-102, conducted in Japan, demonstrated an improvement in overall survival of patients with metastatic colorectal cancer. Taiho took the encouraging results from this Phase II study and completed the required western Phase I studies to initiate a global Phase III program within a 15 month period.

Taiho has established a seamlessly connected research network, consisting of Tsukuba Research Center, Tokushima Research Center, the Taiho Clinical Development Center, and Taiho Pharma USA. The integrated network supports the discovery and development of numerous treatments. The Company’s research achieves the highest standards of drug discovery by letting science guide its development path, and then applying modern technology and innovation to achieve that end. Investigational drugs stemming from this research are being examined as potential stand-alone products, or ones that can be used in combination with existing therapies to potentially enhance the safety and efficacy profile of current cancer options.

Highlights of the preclinical results of Taiho’s investigational drugs being presented at the EORTC-NCI-AACR Symposium include:
