NCT03734029 · Trastuzumab Deruxtecan (DS-8201a) Versus Investigator's Choice for HER2-low Breast Cancer That Has Spread or Cannot be Surgically Removed [DESTINY-Breast04]

Superseded Evidence Record

This page preserves the immutable v0.1.2 record. Its current successor is evt_NCT03734029_v29_v30_9a48cca0a885.

Severity is deterministic, reproducible, uncalibrated triage metadata, not validated review priority or proven wrongdoing. This page states what the registry evidence supports and what it does not support.

Claims Supported

  • TrialDiff compared ClinicalTrials.gov record version 29 to version 30 for NCT03734029.
  • The JSON Patch for this comparison has hash 857ff437dce10fafb759508bac550e4a5ce82eb5bec9274441aa707a2084c797.
  • The active deterministic rule set hash was 318445b9ad266f51fd10ef378645c753ba7a098e3e4395c3c457750dc5f88d86.
  • The deterministic triage label was high; before timing adjustment it was high.
  • The triage label is uncalibrated metadata, not a validated review-priority finding.
  • The patch satisfied these deterministic event-class predicates: outcome_edit_cooccurs_with_results_posting.
  • The timing context for the from-version record was late_recruitment.
  • The deterministic rules that fired were: adverse_event_group_change.
  • The changed JSON Pointer paths were: /protocolSection/statusModule/statusVerifiedDate, /protocolSection/statusModule/completionDateStruct/date, /protocolSection/statusModule/lastUpdateSubmitDate, /protocolSection/statusModule/lastUpdatePostDateStruct/date, /protocolSection/statusModule/resultsFirstSubmitQcDate, /protocolSection/statusModule/resultsFirstPostDateStruct, /protocolSection/outcomesModule/secondaryOutcomes/1, /protocolSection/outcomesModule/secondaryOutcomes/1, /protocolSection/outcomesModule/secondaryOutcomes/3, /protocolSection/outcomesModule/secondaryOutcomes/4, /protocolSection/outcomesModule/secondaryOutcomes/5, /protocolSection/outcomesModule/otherOutcomes, /resultsSection/participantFlowModule/periods/0/milestones/1, /resultsSection/participantFlowModule/periods/0/milestones/2, /resultsSection/outcomeMeasuresModule/outcomeMeasures/2, /resultsSection/outcomeMeasuresModule/outcomeMeasures/2, /resultsSection/outcomeMeasuresModule/outcomeMeasures/4, /resultsSection/outcomeMeasuresModule/outcomeMeasures/5, /resultsSection/outcomeMeasuresModule/outcomeMeasures/6, /resultsSection/outcomeMeasuresModule/outcomeMeasures/11, /resultsSection/adverseEventsModule/timeFrame, /resultsSection/adverseEventsModule/description, /resultsSection/adverseEventsModule/eventGroups/0/deathsNumAffected, /resultsSection/adverseEventsModule/eventGroups/0/deathsNumAtRisk, /resultsSection/adverseEventsModule/eventGroups/1/deathsNumAffected, /resultsSection/adverseEventsModule/eventGroups/1/deathsNumAtRisk, /resultsSection/adverseEventsModule/armsReviewUnit, /resultsSection/adverseEventsModule/allCauseMortalityReviewUnit, /annotationSection, /reviewUnit.
  • The timeline value moved by 366 days.
  • An outcome path changed between versions 29 and 30 in a patch that also carried a hasResults or resultsSection co-occurrence signal.

Claims Not Supported

  • That the amendment was scientifically unjustified.
  • That the change constitutes misconduct or wrongdoing.
  • That sponsor intent can be inferred from this registry change.
  • That the change caused or altered the trial's results.
  • That the change was or was not disclosed in a manuscript.
  • That TrialDiff determines regulatory compliance or non-compliance.
  • That co-occurrence with results posting proves the outcome edit was harmless, administrative, or substantively benign.
  • That event-class membership is a validated global review-priority ranking.

Neutral Review Question
