Since a discontinued programme has little competitive value, a policy (via funders, journals and regulators) that participant-level data from terminated oncology programmes is deposited with open access after 24 months would unlock meta-analysis, biomarker work and methods research.","asOf":"2026-09-08","links":[{"label":"Vivli","url":"https://vivli.org/"},{"label":"YODA Project","url":"https://yoda.yale.edu/"}],"tags":[],"related":["idea-tr2-failed-trial-biobank"],"cancers":[],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-negative-results","b-data-silos"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"Within three years, participant-level data from at least half of terminated phase 2 and 3 oncology programmes is available for download or streamlined access, up from a small minority today.","rationale":"Trial participants consented to advance knowledge; data locked after failure honours neither them nor the science.
