COMIRB at CU Anschutz

Site Specific Information

COMIRB offices are centrally located on campus in the Fitzsimmons Building, third floor, north. We are happy to schedule a meeting to discuss your specific study.


We are also happy to give presentations to classes, research teams, or departments. Contact us if you would like to schedule a presentation.


Full Board and Expedited research must be submitted through the Human Subject Research (HSR) Portal prior to submitting to COMIRB. Research protocols which are exempt do not need to be submitted through the HSR Portal with the exception of research involving the CTRC or CHCO, for whom all research must be submitted through the HSR Portal. When you receive a clearance letter from the HSR Portal, attach that to your COMIRB submission.
