Claims Supported

  • TrialDiff compared ClinicalTrials.gov record version 7 to version 8 for NCT00165256.
  • The JSON Patch for this comparison has hash 22ae109b1766acd909fdfa9e98ee18d0d5ae92a0ec2554237e789ddc28f9a91a.
  • The active deterministic rule set hash was fc87f4f0a74bc789dbe4ba85893c2c96f55db62c22970be4e991288104291621.
  • The deterministic triage label was critical; before timing adjustment it was critical.
  • The triage label is uncalibrated metadata, not a validated review-priority finding.
  • The patch satisfied these deterministic event-class predicates: why_stopped_removed_in_terminal_context.
  • A registry field under the status or stopped-trial explanation module changed between ClinicalTrials.gov versions 7 and 8.
  • The timing context for the from-version record was post_recruitment.
  • The deterministic rules that fired were: arms_or_interventions_change, design_info_change, phase_change, why_stopped_change.
  • The changed JSON Pointer paths were: /protocolSection/statusModule/statusVerifiedDate, /protocolSection/statusModule/overallStatus, /protocolSection/statusModule/whyStopped, /protocolSection/statusModule/completionDateStruct/date, /protocolSection/statusModule/lastUpdateSubmitDate, /protocolSection/statusModule/lastUpdatePostDateStruct/date, /protocolSection/statusModule/lastUpdatePostDateStruct/type, /protocolSection/designModule/studyType, /protocolSection/designModule/patientRegistry, /protocolSection/designModule/designInfo/observationalModel, /protocolSection/designModule/designInfo/timePerspective, /protocolSection/designModule/designInfo/allocation, /protocolSection/designModule/designInfo/interventionModel, /protocolSection/designModule/designInfo/primaryPurpose, /protocolSection/designModule/designInfo/maskingInfo, /protocolSection/designModule/phases, /protocolSection/armsInterventionsModule/armGroups/0/type.
  • The whyStopped value was empty or removed in the changed registry record.
  • The timeline value moved by 944 days.
  • The whyStopped field changed from nonempty to empty or absent in a terminal-status context between versions 7 and 8.
  • The changed paths include the ClinicalTrials.gov whyStopped field, a stopped-trial explanation field relevant to 42 CFR 11.64 when applicable.

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 TrialDiff determines whether the stopped-trial explanation satisfies 42 CFR 11.64.
  • That event-class membership is a validated global review-priority ranking.

Neutral Review Question

Does the public registry record give a specific explanation for the stopped or terminal status?
