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

2026年11月9日 更新者:Novartis Pharmaceuticals

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.

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:

  1. Known second chronic phase (CP) of CML after previous progression to Accelerated Phase (AP)/Blast Phase (BP).
  2. Previous treatment with a hematopoietic stem-cell transplantation.
  3. Patient planned to undergo allogeneic hematopoietic stem cell transplantation

To assess growth and sexual maturation. An X-ray of the left hand and wrist to assess bone age will be performed at screening and every 48 weeks until end of treatment (EOT).

Participants who do not have a baseline Tanner Stage of 5 will continue to be assessed every 24 weeks until achievement of Tanner Stage 5 on both secondary sexual characteristics or EOT, whichever comes first. Once a participant reaches stage 5, examinations do not need to be conducted anymore. For all male participants, Tanner Stage 5 will be achieved once the participant has demonstrated both stage 5 genitalia development and stage 5 pubic hair development. For all female participants, Tanner Stage 5 will be achieved once the participant has demonstrated both stage 5 breast development and stage 5 pubic hair development.
