Decision brief · what the records say, not our assessment
Quizartinib or Placebo Plus Chemotherapy in Newly Diagnosed Patients With FLT3-ITD Negative AML
NCT06578247 · Daiichi Sankyo · PHASE3 · active not recruiting · Open Targets disease: leukemia
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 CSF1R, FLT3, KIT has somatic-mutation evidence in leukemiaRule: Open Targets has somatic-mutation evidence for the target in this cancer. Source: Open Targets: CSF1R in leukemia, 2026-11-11
- Human genetic evidence: no · No germline or somatic evidence for CSF1R, FLT3, KIT in leukemiaRule: Any germline or somatic human genetic evidence for the target in this cancer, counted apart from animal-model and literature evidence. Source: Open Targets: CSF1R in leukemia, 2026-11-11
- Pediatric target: yes · CSF1R, FLT3, KIT 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 NCT06578247, 2026-11-11Published context: Likelihood of approval from phase 1: 7.5% haematologic vs 4.6% solid (BIO / Informa / QLS 2021, 2011–2020).
