Dear visitor,

Welcome to the website of the Dutch Childhood Oncology Group - Early Clinical Trial Consortium (DCOG-ECTC). The DCOG-ECTC is a consortium which aims at implementing early phase clinical trials in children with cancer. The DCOG-ECTC is one of the collaborating partners in ITCC, an European based consortium  to promote the clinical evaluation of new anti-cancer compounds in children with cancer. The consortium consists of  47 European Pediatric Oncology Departments with expertise in conducting early phase trials in children and adolescents, and 9 European research laboratories.

This website has been developed for investigators and their study teams participating in DCOG-ECTC studies. The main goal is to provide the participating sites with all relevant study-related information, and to introduce a tool for the participating sites to implement and perform the DCOG-ECTC early clinical trials.

All participating study teams will be invited by DCOG-ECTC and will receive an account, which you need to log in.
