Stopping Tyrosine Kinase Inhibitors in Affecting Treatment-Free Remission in Patients With Chronic Phase Chronic Myeloid Leukemia

April 18, 2024 updated by: Children's Oncology Group

Stopping Tyrosine Kinase Inhibitors (TKI) to Assess Treatment-Free Remission (TFR) in Pediatric Chronic Myeloid Leukemia - Chronic Phase (CML-CP)

This phase II trial studies how stopping tyrosine kinase inhibitors will affect treatment-free remission in patients with chronic myeloid leukemia in chronic phase. When the level of disease is very low, it's called molecular remission. TKIs are a type of medication that help keep this level low. However, after being in molecular remission for a specific amount of time, it may not be necessary to take tyrosine kinase inhibitors. It is not yet known whether stopping tyrosine kinase inhibitors will help patients with chronic myeloid leukemia in chronic phase continue or re-achieve molecular remission.

Detailed Description

PRIMARY OBJECTIVES:

I. 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).

II. 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.

SECONDARY OBJECTIVE:

I. To describe clinical factors and laboratory correlates affecting the persistence of major molecular remission (MMR) and re-initiation of treatment after stopping TKI (e.g. patient demographics, duration and level of prior molecular remission, duration and type of TKI, clinical presentation at diagnosis and immune studies).

EXPLORATORY OBJECTIVES:

I. To describe change in height standard deviation score over time in patients who are able to discontinue their TKI.

II. To describe the long-term health outcomes including but not limited to gonadal function, endocrine function, and bone metabolism in patients who are able to discontinue TKI as well as those that need to restart TKIs.

III. To describe differences in patient-reported health status after stopping TKIs, including those who need to resume TKI after stopping.

IV. To describe the incidence and characteristics of TKI withdrawal syndrome in children.

V. To evaluate changes in neurocognitive outcomes of patients enrolled on this study using a patient-completed, performance-based, computerized measure of neuropsychological functioning and a parent-report/self-report questionnaire.

OUTLINE:

Patients stop taking TKI medication within 10 days after enrollment. Patients undergo peripheral blood collection to monitor loss of MMR every 4 weeks in year 1, every 6 weeks in year 2, and every 12 weeks in year 3. Patients who lose their molecular remission may restart TKI medication and are monitored every 4 weeks in year 1, every 6 weeks in year 2, and every 12 weeks in year 3.

After completion of study treatment, patients are followed up annually.

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Basic Science (stop taking TKI, biospecimen collection)
Patients stop taking TKI medication within 10 days after enrollment. Patients undergo peripheral blood collection to monitor loss of MMR every 4 weeks in year 1, every 6 weeks in year 2, and every 12 weeks in year 3. Patients who lose their molecular remission may restart TKI medication and are monitored every 4 weeks in year 1, every 6 weeks in year 2, and every 12 weeks in year 3.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Treatment-free remission (TFR)
Time Frame: From date of TKI discontinuation to the date of the first event (molecular recurrence, hematologic relapse, cytogenetic relapse, re-initiation of TKI therapy, second malignant neoplasm, or death) or censoring, assessed up to 2 years
The Kaplan Meier method will be used to estimate 2-year TFR along with a 95% confidence interval.
From date of TKI discontinuation to the date of the first event (molecular recurrence, hematologic relapse, cytogenetic relapse, re-initiation of TKI therapy, second malignant neoplasm, or death) or censoring, assessed up to 2 years
Major molecular remission (MMR/MR3)
Time Frame: Up to 1 year
For patients re-initiating tyrosine kinase inhibitor (TKI) therapy, the cumulative incidence of major molecular remission will be calculated from the time of re-initiating TKI therapy treating deaths prior to achieving major molecular remission as competing events.
Up to 1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical factors and laboratory correlates affecting persistence of MMR
Time Frame: Up to 36 months
Clinical factors and laboratory correlates (e.g. duration and level of prior molecular remission, risk score, duration and type of TKI, disease scoring system and immune studies etc.) affecting persistence of MMR and re-initiation of treatment after stopping TKI will be assessed by Cox proportional hazard regression models.
Up to 36 months
