Decision brief · what the records say, not our assessment
Autophagy Activation for the Alleviation of Cardiomyopathy Symptoms After Anthracycline Treatment, ATACAR Trial
NCT04190433 · Mayo Clinic · PHASE2 · withdrawn · Breast cancer · Open Targets disease: breast carcinoma · Why it stopped
Six questions a reader deciding whether to spend more time on this asks, each answered with flags: yes, no, or not published (hatched), each with its rule and source record. Flags are never added up into a score or a verdict, because published success rates disagree by a factor of two and more.
1. Is the biology right?
- Somatic driver evidence: no · None of ADRB1, ADRB2, ADRB3, ACE, HMGCR, NR3C2 has somatic-mutation evidence in breast carcinomaRule: Open Targets has somatic-mutation evidence for the target in this cancer. Source: Open Targets: ADRB1 in breast carcinoma, 2026-11-11
- Human genetic evidence: no · No germline or somatic evidence for ADRB1, ADRB2, ADRB3, ACE, HMGCR, NR3C2 in breast carcinomaRule: Any germline or somatic human genetic evidence for the target in this cancer, counted apart from animal-model and literature evidence. Source: Open Targets: ADRB1 in breast carcinoma, 2026-11-11
- Pediatric target: no · Not on the FDA listRule: Target is on FDA's Pediatric Molecular Target List (relevant targets); membership alone neither requires nor waives a study. Source: FDA Pediatric Molecular Target List (Listed as February 2026 on the FDA Pediatric Oncology page; the file served is 9.7.22_the_relevant_molecular_target_list.xlsx, whose Summary of Changes sheet is headed 'SEPTEMBER 2022 UPDATE' (footnote date 2022-09-01)), 2026-11-11
- Haematologic cancer: no · Solid tumourRule: From the indication, or the registry conditions when no indication matches. Source: ClinicalTrials.gov NCT04190433, 2026-11-11Published context: Likelihood of approval from phase 1: 7.5% haematologic vs 4.6% solid (BIO / Informa / QLS 2021, 2011–2020). Population-level, not a prediction.

- Primary endpoint is overall survival: no · Delta change in left ventricular ejection fraction [LVEF])Rule: A registered primary outcome measure names overall survival. Source: ClinicalTrials.gov NCT04190433, 2026-11-11Published context: Non-OS primary endpoint: odds ratio 2.79 for a positive phase 3 (Otsuka 2021, 400 phase 3 oncology trials, to 2020). Shown with the next figure: a surrogate is easier to hit, and often a weak guide to survival.Published context: 52% of surrogate-to-OS correlations are low (Prasad 2015, published to 2014).
