NCT04224272 · A Study of ZW25 (Zanidatamab) With Palbociclib Plus Fulvestrant in Patients With HER2+/HR+ Advanced Breast Cancer
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 17 to version 18 for NCT04224272.
- The JSON Patch for this comparison has hash f99a80f22c04de6d6019e0e9d723ac73375af7a7ac419fdd4b0afcbbfb60322a.
- The active deterministic rule set hash was fc87f4f0a74bc789dbe4ba85893c2c96f55db62c22970be4e991288104291621.
- The deterministic triage label was low; before timing adjustment it was low.
- 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 changed JSON Pointer paths were: /protocolSection/statusModule/statusVerifiedDate, /protocolSection/statusModule/lastUpdateSubmitDate, /protocolSection/statusModule/lastUpdatePostDateStruct/date, /protocolSection/statusModule/resultsFirstSubmitQcDate, /protocolSection/statusModule/resultsFirstPostDateStruct, /protocolSection/outcomesModule/primaryOutcomes/2/description, /protocolSection/outcomesModule/primaryOutcomes/2/timeFrame, /protocolSection/outcomesModule/primaryOutcomes/2/reviewUnit, /resultsSection/outcomeMeasuresModule/outcomeMeasures/3/description, /resultsSection/outcomeMeasuresModule/outcomeMeasures/3/timeFrame, /resultsSection/outcomeMeasuresModule/outcomeMeasures/3/reviewUnit, /annotationSection.
- An outcome path changed between versions 17 and 18 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
