Pharmacoeconomic considerations for acute myeloid leukemia pharmacotherapy

Introduction Acute myeloid leukemia (AML) is a rare blood cancer with a poor prognosis. Recently, targeted drugs have improved survival both in the elderly and in fit patients. However, as monthly costs of targeted agents are high, regulatory bodies often impose restrictions on their use. Areas Covered The authors review the value-for-cost of targeted drugs such as gemtuzumab ozogamycin, CPX-351, midostaurin, gilteritinib, glasdegib, venetoclax, oral azacytidine and enasidenib used to treat adult AML. EMBASE and TRIP databases, together with authority websites were searched for technology assessments. Add-on drugs, namely midostaurin and gemtuzumab ozogamycin, have been reported to have the best pharmacoeconomic profile for newly diagnosed fit patients with FLT3 mutation or favorable/intermediate cytogenetics, since allogeneic transplant rates were stable or reduced. Most of the other drugs, on the other hand, did not achieve highly favorable cost-for-benefit, due to a poor absolute survival gain and/or increased transplant rates. Expert opinion The cost of most targeted therapies for AML in unfit patients seems unfair in comparison to the absolute survival advantage provided in fit patients. Point of cure and transplant outcomes should be standardized to allow comparability among the models.
