All CTN studies undergo QA monitoring by the CCC. CCC monitors will:
Conduct site initiation, interim, and close-out visits.
Provide or arrange for training in protocol-specific issues and Good Clinical Practice when needed or appropriate.
Follow-up on issues identified during earlier monitoring visits.
File reports with the CTP, the local Node, the sponsor (NIDA CTN), and the Lead Investigator(s), as required.
