The Dutch Childhood Oncology Group - Early Clinical Trial Consortium (DCOG-ECTC) implements clinical trials in children with cancer, especially early phase trials. Team members of the DCOG-ECTC are based at different locations:

  • ErasmusMC-Sophia Rotterdam
  • Academic Medical Center Amsterdam
  • Princess Maxima Center for Pediatric Oncology Utrecht
  • Netherlands Cancer Institute Amsterdam

The DCOG-ECTC is one of the collaborating partners in ITCC, a European based consortium to promote the clinical evaluation of new anti-cancer compounds in children with cancer.

This website is a tool for investigators and their study teams participating in DCOG-ECTC studies, to manage DCOG-ECTC sponsored trials in an efficient manner. All new study information and information requests to participating sites will be communicated via this website.
