What is the purpose of the study

This is a pilot study to determine the rate of successful treatment-free remission (TFR) in patients who achieved and maintained molecular response 4 (MR4) on ponatinib following at least 4 years of imatinib therapy.

What will happen during the study

This study consists of two phases: the ponatinib consolidation phase (48 weeks) and the ponatinib TFR phase (96 weeks).

In the ponatinib consolidation phase, patients will be treated with ponatinib (15 mg per day). Patients who maintain MR4 during this consolidation phase can attempt stopping ponatinib and will continue in the ponatinib TFR phase.

Key inclusion criteria

This study includes male or female patients who:

  • are aged 18 years or older
  • have an Eastern Co-Operative Group (ECOG) status of 0, 1 or 2
  • have been diagnosed with BCR-ABL positive chronic myeloid leukemia in chronic phase (CP-CML)
  • have been on imatinib as the only TKI treatment for at least 4 years
  • have achieved and maintained MR4 for at least 12 months on imatinib, as determined by polymerase chain reaction (PCR) lab test at screening.

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

Key exclusion criteria

The study does not include patients who:

  • have been in advanced phase or blast phase, or underwent allogeneic stem cell transplant
  • have a known atypical transcript
  • have CML treatment resistant mutation(s)
  • have attempted to permanently discontinue imatinib or ponatinib treatment before.

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