Abstract
To evaluate the difference in time taken for ethics and site governance approval for multicentre clinical trials using two different systems of ethics review. We evaluated the times to final ethics and governance approval for two international, multicentre clinical trials of treatment for metastatic colorectal cancer: the MAX trial, using a non-centralised ethics review system, and the CO.20 trial, using the new New South Wales centralised ethics review system. Time from trial submission to overall study approval. The median time taken to obtain ethics approval for the MAX trial at 16 NSW sites was 100 days (range, 36-161 days). The median time to obtain central ethics approval for the CO.20 trial at 14 NSW sites was 77 days, with an additional 60 days (range 20-79 days) required to obtain site-specific research governance approval. Any difference in time to approval between the review systems was outweighed by the overall time taken. However, the time spent by both the coordinating centre and local sites in collation, submission and correspondence was greatly reduced, and the centralised process allowed for standardised documentation at all study sites.
