The U.S. National Cancer Institute (NCI) produces the Common Terminology Criteria for Adverse Events (CTCAE).
CTCAE aids the reporting of adverse events that occur to patients enrolled in cancer therapy clinical trials.
CTCAE is a standard classification and severity grading scale for adverse events in clinical trials and oncology settings.
CTCAE corresponds with MedDRA at its Adverse Event level. Information systems can integrate CTCAE to exchange safety data and to enable data management for collecting and analyzing adverse event data.
Names with SAB=NCI_CTCAE come from a subset of version 4.3 of CTCAE. For other versions of CTCAE, see:
