The CTRP Accrual web application provides authorized members of the cancer research community with access to cancer clinical trials registered with the CTRP for the purpose of reporting accrual data for clinical studies. It enables users to enter accrual based on the trial category: Complete (National, Externally Peer-Reviewed, or Institutional trials), or Abbreviated (Industrial or Other trials). For information on these types, refer to CTRP Trial Categories, Study Sources or https://cancercenters.cancer.gov/GrantsFunding/eData#dt4.

The CTRP Accrual web application allows users to enter the following types of accrual data:

• Patient level: Study subject demographic data for Externally Peer-Reviewed and Institutional trials. (Accruals for National trials are reported internally at NCI.)
• Summary level: Patient accrual counts for Abbreviated trials that have been abstracted (that is, trials that have been fully abstracted) as well as those that have been approved or withdrawn.
