Funded by SickKids and the Ontario Child Health SUPPORT Unit, the aim of the Clinical Trials Unit (CTU) is to enhance child health through the conduct of high quality clinical trials. CTU staff provides expert methodological, regulatory, and operational support to PIs on the design, conduct, analysis, execution and reporting of clinical trials. All types of trials (drug, device, diagnostic, behavioral), all phases (I-III), investigator-initiated and industry-sponsored trials are eligible for support.
