An area-under-the-curve Markov model was designed to evaluate the cost-effectiveness of ponatinib as a third line treatment of Chronic Myeloid Leukemia-Chronic Phase (CML-CP) with reference to Italy. As for current guidelines, comparators were dasatinib, nilotinib, bosutinib, allogeneic stem cell transplantation (SCT), hydroxyurea. The economic perspective was the Italian National Health Service's (NHS), where costs for treatment drugs, monitoring and follow-up, adverse events, SCT procedure were considered on a lifetime span. Costs (mainly based on current tariffs in Italy) and benefits (QALYs) were discounted at a 3.5% annual rate. Ponatinib resulted dominant versus SCT. The lowest ICER was €13,090 (ponatinib vs hydroxyurea); the highest was €22,529 (ponatinib vs dasatinib). Sensitivity analysis – both deterministic (one way) and probabilistic – was focused on the comparison between ponatinib and dasatinib. The deterministic analysis showed that the most critical parameter in the model was ponatinib pri...
