NCT04043676

Brief Summary

Ponatinib has shown to induce deeper molecular responses compared with imatinib. Therefore, ponatinib treatment could increase the proportion of patients who could discontinue treatment successfully. This strategy that includes treatment change to a more powerful treatment before treatment discontinuation has not been evaluated in any of the previous clinical trials, and will be explored in the current study. In this framework, the purpose is to determine the rate of successful treatment-free remission (TFR) within the first 48 weeks following cessation of treatment in patients who achieved Molecular Response 4 (MR4) on imatinib and maintained MR4 on ponatinib after a switch from imatinib. Eligible patients have been previously treated with imatinib as unique tyrosine kinase inhibitor (at least 4 years) and have documented MR4 (at least 12 months) at the time of switch to ponatinib to study entry.

Outcome Measures

Primary Outcomes (1)

  • Loss MR4

    Proportion of patients without confirmed loss of MR4 or loss of MMR (don't require confirmation) within 48 weeks following ponatinib therapy cessation.

    96 weeks (48 weeks ponatinib consolidation phase plus 48 weeks ponatinib treatment-free remission)

Study Arms (1)

Ponatinib Treatment

EXPERIMENTAL

Patients will be treated with 15 mg/day of ponatinib during 48 weeks. If a patient maintains MR4 throughout the 48 weeks, he/she will be eligible to start the ponatinib TFR phase. If a patient has confirmed loss of MR4 (two consecutive BCR-ABL \> 0.01% IS) or loss of MMR (no confirmation needed), he/she will not be eligible for the TFR phase. Instead, he/she will restart imatinib treatment.

Drug: Ponatinib

Interventions

All patient will take 15 mg/day ponatinib oral during 48 weeks.
