[Dictionary] Vivli (concept)

A non-profit, independent clinical-trial data-sharing platform that hosts a searchable catalogue of individual participant-level data (IPD) from completed clinical trials and mediates researcher access to it through a structured, multi-stage request-and-review process rather than open download. Approved researchers analyze the data inside a browser-based secure research environment; the underlying files are never downloaded to the researcher's own machine. Vivli grew out of a project at the Multi-Regional Clinical Trials (MRCT) Center of Brigham and Women's Hospital and Harvard, and launched publicly in July 2018.
