Étude pour déterminer l'efficacité et l'innocuité de l'asciminib chez les patients pédiatriques atteints de LMC-CP Ph+

9 novembre 2026 mis à jour par: Novartis Pharmaceuticals

Une étude de phase II, multicentrique, ouverte, à bras unique pour évaluer l'innocuité et l'efficacité de l'asciminib chez des participants pédiatriques nouvellement diagnostiqués ou précédemment traités pour une leucémie myéloïde chronique positive au chromosome Philadelphie en phase chronique (LMC-CP Ph+) avec ou sans mutation T315I connue

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.

Description détaillée

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.

  4. 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:

    1. Unfavourable response to TKI is defined following the Apperley et al 2025 guidelines as:

      • At three months after the initiation of therapy: BCR::ABL1 ratio > 10% IS (if confirmed within 1-3 months)

    2. 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.

  2. Previous treatment with a hematopoietic stem-cell transplantation.
  3. Patient planned to undergo allogeneic hematopoietic stem cell transplantation

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.
