Ponatinib Shows Superior Survival Outcomes in Ph+ ALL Patients with Persistent MRD After Induction
- Post hoc analysis of the PhALLCON trial demonstrates that ponatinib achieved higher rates of deep molecular responses compared to imatinib in newly diagnosed Ph+ ALL patients who remained MRD-positive after induction therapy.
- Patients with persistent MRD who continued ponatinib beyond cycle 3 showed significantly improved event-free survival with a median not reached versus 24.8 months for imatinib (HR 0.198, P = 0.0004).
- The analysis supports continuing ponatinib treatment in Ph+ ALL patients who fail to achieve MRD negativity after initial induction, though researchers caution about the small patient numbers and potential selection bias.
