Clinical trials · failure tracking
Oncology studies whose overall status is TERMINATED, WITHDRAWN or SUSPENDED on ClinicalTrials.gov, with the stop reason exactly as the registrant posted it. A category is attached only when an explicit keyword rule matches the text; CancerIndex never infers why a study stopped.
5 stopped studies mapped to Anal Squamous Cell Carcinoma and descendants · 100% state a reason
Over the 5 studies matching the cancer, status and year filters (the category filter does not change this chart). Each study is counted once, in the first matching category; greyed bars are studies whose text matched no rule or was empty.
Computedrules ci-stop-reasons-v1 · keyword matching only
A category is assigned when one of its keywords appears in the posted text (case-insensitive, whole words). Rules are tested in this order and the first match wins; every match is kept in the API (reasonMatches).

Stop reasons are registrant-reported free text and are displayed verbatim (truncated; hover for the full text). Categories come from explicit keyword rules and are never inferred from the study design, sponsor or outcome; a study that stopped for several reasons is filed under the first rule that matched. A TERMINATED status does not imply a negative result.
