TAIPEI, Taiwan, Oct. 30, 2016 /PRNewswire/ -- TaiGen Biotechnology Co., Ltd. ("TaiGen") announced today that its wholly owned subsidiary, TaiGen Biopharmaceuticals Co. (Beijing), Ltd. has signed an agreement with YiChang HEC ChangJiang Pharmaceutical Co., Ltd ("HEC") to establish a new company ("Newco") in mainland China for the joint development, manufacturing, and commercialization of direct-acting antiviral agents (DAAs) for all-oral interferon-free treatments of chronic hepatitis C virus (HCV) infection in the Greater China region (mainland China, Taiwan, Hong Kong, and Macau). The Newco will be the first of its kind in a cross-strait partnership in the pharmaceutical industry. It also formalized the collaboration in the MOU signed in February 2016.
Under the terms of the Agreement, the Newco will be capitalized at RMB 680 million (US$102 million). TaiGen will use the intellectual property rights of furaprevir (TG-2349) in Greater China as contribution in kind for 49% equity in the Newco. HEC will use the intellectual property rights of yimitasvir (DAG-181) in Greater China as contribution in kind and an additional cash investment in exchange for 51% equity in the Newco. TaiGen will be responsible for research, clinical development, and registration and HEC will be responsible for operation, manufacturing, sales and marketing of HCV treatment based on furaprevir and yimitasvir.
Upon the establishment of the Newco, TaiGen and HEC will execute a separate share transfer agreement where TaiGen will receive from HEC a sum between US$20 to 40 million based on the Phase 2 clinical trial results. After the share transfer is complete, TaiGen will hold 40% equity and HEC 60% equity in the Newco.
TaiGen's furaprevir, a HCV NS3 protease inhibitor, is completing a Phase 2 clinical trial in HCV genotype 1b patients in Taiwan. HEC's yimitasvir, an NS5a inhibitor, has completed in Phase 1 trial in mainland China. Both furaprevir and yimitasvir are DAAs, classified as Class 1.1 by CFDA, and were discovered and developed in-house by TaiGen and HEC respectively.
According to the estimates from WHO and IMS, the number of HCV patients in mainland China ranges from 10-40 million making it the largest HCV market in the world. At present, less than 10% of the HCV patients are receiving treatment. This is due to low awareness of the disease and the severe and intolerable side effects of interferon-based treatment.
Although all-oral interferon-free DAA-based HCV regiments are already available in many countries, none of these are currently approved in mainland China. To expedite the approval and availability of the revolutionary treatment, China's Center for Drug Evaluation has begun to grant priority review status to HCV drugs in development. Furaprevir was granted priority review in April 2016 and TaiGen is the only Taiwanese firm among the seven companies that receive priority review.
Dr. Ming-Chu Hsu, Chairman and CEO of TaiGen said "Mainland China remains the largest untapped HCV market. We are confident that combining both drugs and company expertise will accelerate the development of our DAA regiment and become a formidable competitor in the Greater China HCV market. This partnership with HEC will be another significant milestone in TaiGen's history and take TaiGen to the next level."
Mr. Show-Chung Ho, Chairman of TaiGen's Steering Committee commented, "TaiGen has a successful track record in clinical development and obtaining market approval in mainland China. HEC has the integrated marketing and distribution channels. The synergy that the two companies and their drugs create will bring tremendous benefits to the HCV patients in this region."
