Vivli is a global data-sharing and analytics platform, which aggregates participant-level data from completed clinical trials, to share with the international research community. Vivli evolved from a project of The Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard (MRCT Center), to improve access to clinical trial data and encourage data sharing and transparency. The platform includes an independent data repository and search engine. Vivli remains independent of data contributors, data users, and the broader research community.
