Ancillary Studies

General Information

Ancillary studies are investigations that are not part of the REPRIEVE (A5332) trial, but that propose questions and test hypotheses that are relevant to and further the goals and purposes of REPRIEVE. It is recognized that well designed ancillary studies, consistent with the goals of REPRIEVE, can leverage the trial’s resources to provide critical answers to highly relevant questions for the field. Successful ancillary studies should be able to secure adequate funding through peer review, either through the ACTG, NIH or other funding sources. To protect the integrity of the REPRIEVE trial, ancillary study proposals must be reviewed and approved by the REPRIEVE Ancillary Studies Committee and the Data and Safety Monitoring Board (DSMB) prior to implementation. In addition to meeting the standard for high scientific merit, the major criterion for approval of an ancillary study is that it does not negatively impact the conduct of the parent REPRIEVE trial.


A REPRIEVE ancillary study is defined as research that (1) has not been previously described in the REPRIEVE trial protocol (2) derives new data through the collection of additional imaging, biomarkers, or additional clinical data during the course of the trial (3) does not interfere with the goals and objectives of the REPRIEVE and (4) follows all policies and procedures of the REPRIEVE trial.

For more information on the policies and procedures of the REPRIEVE trial, please read the REPRIEVE Ancillary study policy regarding analyses, timing and content of publications.
