The current CTEP website at ctep.cancer.gov is scheduled to be retired on the evening of July 9, 2025, and all information will be relocated to new URLs. This will affect the location of the NCI Guidelines: Adverse Event (AE) Reporting Requirements, NCI's Common Terminology Criteria for Adverse Events (CTCAE), and other resources. The new location of these materials will be communicated on the CTSU website once the move is complete. This move will also impact other documentation on the CTSU website; CCTG will update all links to reflect the new URLs. Note: ctep.cancer.gov links will be moving, but other websites, including dcp.cancer.gov, ncorp.cancer.gov, and ctepcore.nci.nih.gov, will not be changed.
