About CTRP

NCI's Clinical Trials Reporting Program (CTRP) fulfills a recommendation made by the NCI Clinical Trials Working Group (CTWG) to the National Cancer Advisory Board. CTRP is designed to be a comprehensive database of regularly updated information, including accrual, on all NCI supported clinical trials. This comprehensive database of the entire NCI portfolio will help identify gaps in clinical research and duplicative studies, as well as facilitate effective clinical trial prioritization. To learn more about the history and goals of CTRP, visit the NCI's CTRP Web Page.

CTRP Web Applications

CTRP applications, hosted by NCI, are available to registered users. Refer to the instructions in Creating New NCI CTRP User Accounts to learn more about requesting a user account.

Two of these applications are designed specifically for members of the clinical research community; others are designed for use by NCI staff and contractors only. To learn more about which of the CTRP applications are applicable to you, visit NCI's CTRP Web Page.
