Dr Yasuhiro Ogawa

Scientific Advisor / Emeritus Professor at Kochi University

The inventor of KORTUC (Code name: KRC-01) and an emeritus professor at Kochi University, Dr. Yasuhiro Ogawa is a radiation oncologist and has been at the front of cancer radiotherapy for over 30 years.
In 1988 he was engaged in research of breast conserving therapy as the most advanced treatment at that time in British Columbia Cancer Agency (BCCA) in Canada, which led him to establish a curative breast conserving therapy. After 10 years of research, he invented a new radiotherapy using hydrogen peroxide as radiosensitizer named “KORTUC (Code name: KRC-01)” in 2006. Since then, he has treated more than 250 patients with various types of solid tumor and published its safety and efficacy in many papers (see references).
Dr. Yasuhiro Ogawa obtained MD and PhD of Medicine from Kobe University. Currently, he serves as Director of Kochi General Rehabilitation Hospital. He is also a medical advisor for KORTUC.


How it all started and the story behind the R&D

  • The core technology of KORTUC which stands for “Kochi Oxydol Radiation Therapy for Unresectable Carcinomas” was invented by Dr. Yasuhiro Ogawa, a professor emeritus at Kochi University in Japan. He as radiation oncologist with over 30 years of experience had been searching for a way to cure patients who suffer from non-operatable tumors and who wants to avoid surgical resections.
  • With very limited financial resources, he has been studying to find the solution for the limits of radiotherapy on his own. Through thousands of cancer cases he treated as a practitioner, he accidentally discovered the hydrogen peroxide (H2O2) is the ultimate and very simple way to eliminate hypoxia in tumors.
  • KORTUC INC. was established in 2015 to conduct clinical studies and commercialize Dr. Ogawa’s discovery as the drug.
