About this study

Official title: A Multi-center, Open-label Study to Determine the Dose and Safety of Oral Asciminib in Pediatric Patients With Philadelphia Chromosome Positive Chronic Myeloid Leukemia in Chronic Phase (Ph+ CML-CP), Previously Treated With One or More Tyrosine Kinase Inhibitors

The aim of this study is to support development of asciminib in the pediatric population (1 to <18 years) previously treated with one or more TKIs. Full extrapolation of the efficacy of asciminib from adult to pediatric patients will be conducted. Full extrapolation is based on the concept that CML in the pediatric population has the same pathogenesis, similar clinical characteristics and progression pattern as in adults.

Read the detailed description

The aim of this study is to support development of asciminib in the pediatric population (1 to <18 years) with Philadelphia chromosome positive chronic myeloid leukemia in chronic phase (PH+ CML-CP) previously treated with one or more Tyrosine kinase inhibitor (TKIs).

The primary objective of this study is to characterize the pharmacokinetic (PK) profile of asciminib in pediatric patients with the goal of identifying the pediatric formulation dose (fed) leading to asciminib exposure comparable to 40 mg BID in adult patients (fasted).

The pediatric formulation group will include at least 15 participants in each of the following two age categories: 1 to <12 years and 12 to <18 years; leading to at least 30 participants enrolled treated with the pediatric formulation. It will consist of a dose determination part (Part 1) and a cohort expansion (Part 2 BID regimen and Part 3 QD regimen).

In Part 1, 4-6 participants will be enrolled in order to obtain at least 4 participants evaluable for PK (these participants may be from either of the age categories described above). The initial starting dose will be based on body weight and will be administered BID with food.

Once the body weight adjusted dose has been determined in Part 1 of the study, the patients will be enrolled in Part 2 until at least 20 participants, including those who were included in Part 1, have been enrolled (10 per age group) in the pediatric formulation group. Once the interim safety and PK analysis 2 is completed for one of the age groups, the Part 3 QD regimen will open for the respective age group to enroll 10 patients (5 patients by age group).

Due to the fact that the pediatric formulation was in development and was not available, this study started with the recruitment of adolescent patients. These participants aged 14 to <18 years, weighing at least 40 kg receive the adult formulation at a flat dose of 40 mg BID under fasted conditions.

The total duration of the treatment period of the study will be 5 years (260 weeks). Participants who, according to Investigator's judgement, are benefiting from study treatment will remain on treatment up to the completion of the treatment period (Week 260/5 years).

The primary analysis for the BID regimen is planned after all participants in Part 1 and 2 have completed at least 52 weeks of study treatment or discontinued earlier.

The primary analysis for combined regimen (BID+QD) is planned after all participants in Part 1, 2 and 3 have completed at least 52 weeks of study treatment or discontinued earlier.

    Measured: 52 weeks

  5. Secondary PK parameter: Ctrough

    Goal: identifying the pediatric formulation dose (fed) leading to asciminib exposure comparable to 40 mg BID in adult patients (fasted).

    Measured: 52 weeks

Secondary outcomes (3)
  1. Hematologic responses

    Complete hematological response will be defined as all of the following present for ≥ 4 weeks:

    • WBC count < 10 x 10^9/L
    • Platelet count < 450 x 10^9/L
    • Basophils < 5%
    • No blasts and promyelocytes in peripheral blood
    • Myelocytes + metamyelocytes < 5% in peripheral blood
    • No evidence of extramedullary disease, including spleen and liver

    Measured: 52 weeks

  2. Molecular responses

    To assess pharmacodynamic markers of asciminib's anti-leukemic activity. Molecular response will be assessed by Breakpoint Cluster Region gene-Abelson proto-oncogene (BCR-ABL) 1 level.

    Measured: 52 weeks

  3. Questionnaire on acceptability and palatability after first dose, 4 and 52 weeks

    To assess acceptability and palatability of the pediatric formulation

    Measured: after first dose at Week 1 Day 1, 4 weeks, 52 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Asciminib Pediatric formulation group and Asciminib Adult formulation group in people with Myeloid Leukemia, Philadelphia Positive, run by Novartis Pharmaceuticals at 39 sites in 14 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 25 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 39 sites in United States, China, France, Italy, Germany and 9 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Novartis Pharmaceuticals (1-888-669-6682, novartis.email@novartis.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Pharmacokinetic (PK) parameter: AUClast (time frame: 52 weeks). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2026.
