Popis: The experience of third-generation tyrosine kinase inhibitor ponatinib treatment in Philadelphia chromosome-positive acute lymphoblastic leukaemia (Ph'+ ALL) patients post-allogeneic transplantation is limited. We retrospectively collected data on 25 Ph'+ ALL patients who were started on ponatinib after allogeneic transplantation between July 2015 and July 2019 from nine transplantation centers in Italy. Ponatinib was given in prophylaxis in five (20%), as pre-emptive treatment in seven (28%), and as salvage therapy in thirteen (52%) patients. It was combined with donor leukocyte infusions in ten patients. Half of the patients (12/25) harbored T315I mutation of BCR/ABL1, while in the remaining mutational analysis was negative or not performed. Among the 20 patients who received ponatinib as pre-emptive/salvage treatment, complete molecular response was achieved in 15 (75%) patients. Estimated overall survival at 2-year post-initiation of treatment in the whole cohort was 65% (respectively 60%, 60%, and 78% for the prophylaxis, pre-emptive, and salvage therapy groups). In patients with T315I-positive mutational status, the estimated 2-year survival was 40%. Fourteen patients (56%) experienced toxicity, requiring temporary or definitive suspension of treatment. In conclusion, treatment of Ph'+ ALL patients with ponatinib after transplantation is effective, although the question of adequate drug dose and treatment duration remains unanswered.
