Evaluation of DASATINIB Monotherapy Efficacy in Acute Myeloid Leukemia Patients Refractory to VENETOCLAX-AZACITIDINE
NCT06055621 · Institut Paoli-Calmettes · PHASE2 · suspended · Acute myeloid leukemia · Open Targets disease: acute myeloid leukemia · 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: yes · ABL1, BCR in acute myeloid leukemiaRule: Open Targets has somatic-mutation evidence for the target in this cancer. Source: Open Targets: ABL1 in acute myeloid leukemia, 2026-11-11Published context: 2.3× relative success for targets with somatic (IntOGen) support in oncology (Minikel et al., Nature 2024, drug programs to 2023). A ratio between groups, not a probability for this program; mostly phase 2 to 3.
- Human genetic evidence: yes · ABL1: somatic; BCR: somaticRule: Any germline or somatic human genetic evidence for the target in this cancer, counted apart from animal-model and literature evidence. Source: Open Targets: ABL1 in acute myeloid leukemia, 2026-11-11Published context: 2.6× relative probability of success, phase 1 to launch, with human genetic support (Minikel et al., Nature 2024, drug programs to 2023). All therapy areas, mostly germline evidence; not a probability for this program.
- Pediatric target: yes · ABL1 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: yes · HaematologicRule: From the indication, or the registry conditions when no indication matches. Source: ClinicalTrials.gov NCT06055621, 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 · tumor responseRule: A registered primary outcome measure names overall survival. Source: ClinicalTrials.gov NCT06055621, 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). Shown with the figure above.
