Ph+ CML-CPの小児患者におけるアシミニブの有効性と安全性を評価する研究
新規診断または既治療のフィラデルフィア陽性慢性骨髄性白血病慢性期(Ph+ CML-CP)の小児参加者(既知のT315I変異の有無を問わず)におけるアスシミニブの安全性と有効性を評価するための第II相、多施設、非盲検、単一群試験
The aim of this study is to support development of asciminib in the pediatric population (1 to < 18 years) with Ph+ CML-CP. The study will evaluate the efficacy and safety of asciminib in pediatric formulation (weigh-based dose, fed state) or adult formulation (fasted) in newly diagnosed and resistant or intolerant Ph+ CML-CP with or without T315I mutation.

詳細な説明
This is a multi-center, open-label, single arm study of asciminib in pediatric participants aged
1 to <18 years old with Ph+ CML-CP newly diagnosed and previously treated with TKI treatment, with or without T315I mutation.
The study population will consist of three cohorts of Ph+ CML-CP pediatric participants:
- Newly-diagnosed Ph+ CML-CP participants without known T315I mutation
- Ph+ CML-CP participants resistant or intolerant to previous TKI without known T315I mutation
- Ph+ CML-CP participants with known T315I mutation irrespective of prior TKI treatment
There is no fixed duration of study treatment for the participants. The study will end 5 years (240 weeks) after the last enrolled participants received their first dose of treatment in the study. The objective is to have enough follow up for safety, including growth and development and efficacy.

Male or female participants 1 and < 18 years of age at study enrollment
-
Diagnosis of CML-CP (Apperley et al 2025) with cytogenetic confirmation of Philadelphia positive (Ph+) chromosome
-
For participants with CML-CP newly diagnosed within 3 months of screening OR 5 For participants with CML - CP with high risk of developing resistance or intolerance to previous TKI:
-
Unfavourable response to TKI is defined following the Apperley et al 2025 guidelines as:

- At any time loss of previous response
- At any time emergent resistant BCR::ABL1 mutations or high-risk ACA from prior TKI treatment as per local test results
-
Intolerance to TKI is defined as:
- Non-hematologic intolerance: participants with grade 3 or 4 toxicity while on therapy (in which case the patient is eligible whether or not there was a dose reduction); or with persistent grade 2 toxicity unresponsive to optimal management including dose adjustments (unless dose reduction is not considered in the best interest of the patient if response is already suboptimal)
- Hematologic intolerance: participants with grade 3 or 4 toxicity (absolute neutrophil count [ANC] or platelets) while on therapy that is recurrent after dose reduction to the lowest doses of the TKI
-
6. Evidence of typical BCR::ABL1 transcript [e14a2 and/or e13a2] at the time of screening which are amenable to standardized RQ-PCR quantification.
7. Performance status: Karnofsky ≥ 50% for participants ≥ 16 years of age, and Lansky ≥ 50 for participants < 16 years of age at the time of screening.
Key Exclusion Criteria:
- Known second chronic phase (CP) of CML after previous progression to Accelerated Phase (AP)/Blast Phase (BP).
- Previous treatment with a hematopoietic stem-cell transplantation.
- Patient planned to undergo allogeneic hematopoietic stem cell transplantation
- Known presence of a BCR::ABL1 mutation with known resistance to study treatment in accordance with the most recent public version of international CML clinical guidelines (e.g. NCCN CML treatment guidelines v 1.2026 and Apperley et al 2025) any time prior to study entry
Other inclusion/exclusion criteria may apply.
