Office of the Institutional Review Board

New Clinical Trial Submission Process

Clinical trials must be reviewed and cleared by the Clinical Trials Office (CTO) before the research application can be submitted to the IRB.

CTO pre-review is not applicable to human subjects research that does not meet the definition of a clinical trial.
CTO full-review applies to all studies in which patients are being compensated and/or a study has been identified as having a potential billing risk.
