What is the purpose of the study

This is a study to assess whether reducing the tyrosine kinase inhibitor dose before treatment discontinuation can lead to better rates of treatment-free remission (TFR) than stopping the tyrosine kinase inhibitor dose suddenly before treatment discontinuation.

What will happen during the study

In this study, participants will be randomly assigned to one of two treatment groups:

  • Group A: Patients will continue taking their tyrosine kinase inhibitor received at randomization at a 50% reduced dose.
  • Group B: Patients will continue taking their tyrosine kinase inhibitor received at randomization without changing the dose.

Then, at 12 months after randomization, patients in both groups will stop their tyrosine kinase inhibitor treatment. The treatment-free remission results at 24 months will be compared between the two groups.

Key inclusion criteria

This study includes patients of all sexes who:

  • are aged 18 years or older
  • have been diagnosed with chronic phase chronic myeloid leukemia (CP CML) according to WHO 2016 criteria with a typical BCR::ABL1 rearrangement
  • have received treatment with imatinib for at least 4 years / a second-generation TKI for at least 3 years and who have not had a change of TKI or decrease in dosage in the last 6 months prior to inclusion.
  • have had a deep molecular response for at least 1 year.

Further criteria apply. Please discuss these with your doctor or study staff.

Key exclusion criteria

This study does not include patients who:

  • have progressive severe conditions of poor prognosis immediately compromising participation in the entire study and/or with uncontrolled chronic conditions.
  • have an ECOG of 3 or higher.
  • have previously been resistant to a TKI.
  • have previously attempted to stop TKI treatment.

Further criteria may apply. Please discuss these with your doctor or study staff.
