Implementing Good Clinical Practice in two noncommercial phase II studies in children with cancer.

Background: In noncommercial clinical drug research the implementation of the principles of Good Clinical Practice (GCP) has been criticized for introducing unnecessary bureaucracy at the expense of scientific activity, especially when small populations such as children or patients with orphan diseases are concerned.

Patients And Methods: From May 2003 to September 2005, we conducted two prospective open-label multicenter phase II studies in pediatric oncology. Aside from medical questions, these studies set out to explore the requirements according to the essential standards of the ICH-GCP Guideline in anticipation of the implementation of the EU Regulation in German Drug Law in August 2004; the latter, prospective investigation was initiated by the Coordinating Center for Clinical Trials (KKS).
