Undersøgelse for at fastslå effektiviteten og sikkerheden af Asciminib hos børnepatienter med Ph+ CML-CP

9. november 2026 opdateret af: Novartis Pharmaceuticals

En fase II, multicenter, åben-label, enkelt-armet undersøgelse til evaluering af sikkerheden og effektiviteten af Asciminib hos pædiatriske deltagere, der er ny-diagnosticerede eller tidligere behandlede med Philadelphia-positiv kronisk myelogen leukæmi i kronisk fase (Ph+ CML-CP) med eller uden kendt T315I-mutation

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.

Detaljeret beskrivelse

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.
