Toyama Chemical Co., Ltd. Initiates Phase 2 Clinical Trial in the US of its Anti-influenza Drug Candidate T-705
February 15, 2010

Toyama Chemical Co., Ltd. (Headquarters: Tokyo, Japan; President: Masuji Sugata, “Toyama Chemical”), a subsidiary of FUJIFILM Holdings Corporation, announced today that it has started Phase 2 clinical trial in the US of its novel anti-influenza drug T-705 (generic name: favipiravir).

In the US, clinical trials have been conducted since March 2007, and in the current Phase 2 clinical trial, Toyama Chemical will conduct a randomized, double-blind study evaluating the efficacy and safety of high and low doses of T-705 compared to placebo in patients with influenza A or B.

T-705 is an RNA polymerase inhibitor with a novel mechanism of action. It has already shown signs of efficacy in another Phase 2 clinical trial conducted in Japan. Currently, a Phase 3 clinical trial in Japanese patients with influenza including H1N1 has been ongoing since October 29, 2009.

T-705 could become extremely valuable in providing an alternative influenza therapy, especially in terms of fighting emerging resistant viral strains. This is due to its novel mechanism of action which involves direct inhibition of viral RNA reproduction, while existing anti-influenza drugs only prevent the spread of infection to adjacent cells by inhibiting viral release from host cells.

Toyama Chemical specializes in pharmaceutical research and development, and strives to “contribute to the further development of global health care through new drug development”.
