[Integration Process of Clinical Trial Data in ARCAD-Asia].

In Europe and the United States, the Foundation Aide et Recherche en Cancérologie Digestive(ARCAD)database project was initiated in 2006 and 43,488 patient data(IPD)for metastatic colorectal cancer from 59 trials have been collected and constructed as the integrated database. The ARCAD-Asia was launched in 2021 and has been actively collecting Asian clinical trials and converted IPD are stored into the integrated database. In addition, the ARCAD-Asian data are transferred to ARCAD and IPD are integrated to ARCAD global database. All the data are shared with 3 data centers of ARCAD-Asia and ARCAD, located in France, the United States and Japan. In the ARCAD database, there are 1,673 IPD treated with placebo in a salvage line setting. We are now planning to utilize placebo IPD as the synthetic control arms(SCAs)to compare the efficacies of active agents. Furthermore, we will continue to collect the Asian IPD and will expand the cancer type, leading to more comprehensive global database.
