We are aware about the following current ongoing studies in pediatric CML:

Molecular signature to predict response to TKI in a pediatric population
CML pediatric ITK response according to molecular identification at diagnosis (CML Piramid)
(ClinicalTrials.gov Identifier: NCT05605379)

This obervational study investigates retrospectively on DNA at diagnosis of 88 CP-CML children the mutation status of 64 genes by next generation sequencing and to see if there is an association with the response to TKI treatment. 

Sponsor: University Hospital, Bordeaux
Status: Recruiting (estimated enrollment: 88 participants)
More information: https://www.clinicaltrials.gov/study/NCT05605379?cond=Pediatric%20CML&rank=2

Asciminib Study:
A multi-centre, 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
(ClinicalTrials.gov Identifier: NCT04925479)

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.

Sponsor: Novartis Pharmaceuticals
Status: Recruiting (estimated enrollment: 34 participants)

Bosutinib Phase I/II Study:
A phase I/II study of bosutinib in pediatric patients with newly diagnosed chronic phase or resistant/intolerant Ph+ chronic myeloid leukemia
(ClinicalTrials.gov Identifier: NCT04258943)
Phase 1-2, multicenter, international, single-arm, open-label study designed to identify a recommended dose of bosutinib administered orally once daily in pediatric patients with newly diagnosed chronic phase Ph+ CML (ND CML) and pediatric patients with Ph+CML who have received at least one prior TKI therapy (R/I CML), to preliminary estimate the safety and tolerability and efficacy, and to evaluate the PK of bosutinib in this patient population.

Sponsor: Children's Oncology Group
Status: Active, not recruiting (estimated enrollment: 60 participants)
More information: https://clinicaltrials.gov/ct2/show/NCT04258943?term=children&cond=CML&draw=2&rank=9

Ponatinib Phase I/II Study:
An open-label, single-arm, phase 1/2 study evaluating the safety and efficacy of ponatinib for the treatment of recurrent or refractory leukemias or solid tumors in pediatric patients
(ClinicalTrials.gov Identifier: NCT03934372)
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and efficacy of ponatinib in children aged 1 to < 18 years with advanced leukemias, lymphomas, and solid tumors.

Sponsor: Incyte Biosciences International
Status: Recruiting (estimated enrollment: 60 participants)
More information: https://www.clinicaltrials.gov/ct2/show/NCT03934372?term=Pediatric+CML&draw=3&rank=14

TFR Study
Stopping tyrosine kinase inhibitors (TKI) to assess treatment-free remission (TFR) in pediatric chronic myeloid leukemia chronic-phase (CML-CP)
(ClinicalTrials.gov Identifier: NCT03817398)

• To determine the 2-year treatment free remission (TFR) rate of children, adolescents, and young adults with chronic myeloid leukemia - chronic phase (CML-CP) following discontinuation tyrosine kinase inhibitor (TKI).
• To estimate the re-induction rate and maintenance of molecular remission (BCR-ABL1 =< 0.1%) at 1 year after restarting TKI for children, adolescents, and young adults.

Sponsor: Children's Oncology Group
Status: Active, not recruiting (estimated enrollment: 110 participants)

International Chronic Myeloid Leukemia Pediatric Study (ICMLPed)
Treatments and outcomes in children and adolescents
Prospective, observational study to describe and characterize CML in a large pediatric cohort of patients
(ClinicalTrials.gov Identifier: NCT01281735)

Sponsor: Poitiers University Hospital
Status: Recruiting (estimated enrollment: 750 participants)
More information: https://www.clinicaltrials.gov/ct2/show/NCT01281735?cond=pediatric+cml&draw=10&rank=7

Dasatinib Study
A phase II Study of dasatinib in children and adolescents with newly diagnosed chronic phase chronic myelogenous leukemia (CML) or with Ph+ leukemias resistant or intolerant to imatinib
The purpose of this study is to determine whether dasatinib is safe and effective in children and adolescents with newly diagnosed chronic myeloid leukemia (CML), or in children with Ph+ acute lymphoblastic leukemia (ALL), accelerated or blast phases CML who relapse after imatinib or who are resistant or intolerant to imatinib. The side effects of this oral investigational drug in children and adolescents will be evaluated.
(ClinicalTrials.gov Identifier: NCT00777036)

Status: Active, not recruiting (estimated enrollment: 130 participant)
