COVID-19 studies are our top priority. For all other studies, we recommend commencing the registration process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission as we are experiencing 4 week turn-around time in review of submissions and resubmissions. We currently do not have the capacity to expedite reviews.

Note also there are additional delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Outcomes
Primary outcome [1] 0 0
Objective Response Rate (ORR) of Pembrolizumab + Epacadostat, Pembrolizumab Monotherapy and the EXTREME Regimen - ORR was defined as the percentage of participants who had a complete response (CR), disappearance of all target lesions or partial response (PR), >=30% decrease in the sum of the longest diameter of target lesions per RECIST v1.1 by investigator determination.
Responses are based on investigator assessments per RECIST 1.1 without confirmation using all available scans.
