About Gongwin BioPharm Holdings, Co., Ltd.

Gongwin Biopharm Holdings, Co., Ltd. Cayman (Gongwin-KY; ticker: 6617) founded in 2014 is a Taiwan-based clinical-stage biopharmaceutical company focused on developing novel anti-cancer drugs. We adopt an innovative anti-tumor therapy called “minimally-invasive targeted tumor ablation” (MITTA) therapy for the treatment of focal malignancies. In 2017, Gongwin-KY has been granted “Biotech New Drug Company” designation by MOEA, Taiwan and became a public trading company at Taipei Emerging Stock Board.

The proprietary core technology of Gongwin-KY is intratumoral injection of PTS (para-toluenesulfonamide) by combining the active therapeutic agent-PTS and minimally-invasive intervention, which is unique and distinct from traditional anti-tumor therapies. The advantages include targeting specific tumors plus the nature of high selectivity of PTS on tumor cells. Based on a completed Phase III clinical trial conducted in China, PTS MITTA therapy has demonstrated its safety showing minimal damages to adjacent normal cells and efficacy by statistical analysis. Gongwin-KY is confident to provide PTS MITTA as a better novel anti-cancer treatment option.

In addition to the development of anti-cancer drugs, Gongwin-KY has been working on other novel drugs for unmet medical needs. To expand our R&D capacity, Gongwin-KY plans to build a GMP-equivalent pilot laboratory qualified for conducting optimization of drug formulation, animal study, and manufacturing of pilot-scale API. We expect the development timeline of PTS novel drugs will be expedited with this new laboratory to be completed in 2019.

Dr. Wu, the inventor of PTS, and Dr. Shih have been conducting various exploratory studies on PTS since 1980s. In 2000, PTS International Inc., Texas, USA, and Beijing Vision Drugs Development Limited were established in China to conduct multiple pre-clinical studies and clinical trials. Since then, we have accumulated a great deal of clinical data and experience on PTS anti-cancer therapy. In 2011, a Phase III multi-center, non-randomized, single-arm, open-label trial has been completed in China. Afterward, a category 1.1 NDA has been submitted to China FDA. In order to accommodate the local regulatory affairs and markets in China, Tianjin Chase Sun Jiandakang Pharmaceutical Technology Co., Ltd. was founded by PTS International Inc. and Tianjin Chase Sun Pharmaceutical Co., Ltd. to be responsible for the license registration and manufacturing of PTS for China market.
