About Voluntary Organization JBCRG
The Voluntary Organization JBCRG was established on April 21, 2002, to plan and conduct breast cancer clinical trials, JBCRG-01, 02 (02'), 03, M01, and 04.
Even after the foundation of the Limited Liability Intermediary Corporation JBCRG (now the General Incorporated Association JBCRG), these clinical trials were accomplished by the Voluntary Organization.
All the business carried out by the Voluntary Organization was succeeded to the General Incorporated Association by a business transfer agreement signed on June 28, 2019.
On November 30, 2019, when the initial purpose of the trials was completed, the Voluntary Organization was dissolved, and its activities ended.
