A Systematic Literature Review of the Economic Evaluations of Treatments for Patients with Chronic Myeloid Leukemia

Background and Objectives The management of chronic myeloid leukemia is associated with an extensive economic burden, and as novel interventions are being tested in this disease, understanding the comparative effectiveness is of interest. Findings and conclusions of this important issue continue to evolve with improvements in clinical research and economic understanding. This systematic literature review aims to conduct a comprehensive assessment of economic evaluations in chronic phase chronic myeloid leukemia. Methods Embase ® , MEDLINE ® , and the National Health Service Economic Evaluation Database were searched on 4 July, 2022 to identify economic evaluations of chronic myeloid leukemia. Health technology assessment websites and key conference proceedings were also searched. Economic evaluations comparing treatment options in adult patients with chronic phase chronic myeloid leukemia were included. The quality of the studies were assessed using Drummond’s checklists. Results The search retrieved 47 studies and 16 health technology assessments that fulfilled the eligibility criteria. Most were cost-utility analyses (23 studies and 11 health technology assessments) and were from the USA ( n = 15) and China ( n = 7). Twenty-seven studies and six health technology assessments included only patients with chronic phase chronic myeloid leukemia. Most models had a Markov structure, a 1 year to lifetime time horizon, and a 1-month cycle length. Commonly assessed treatments were various tyrosine kinase inhibitors (imatinib, nilotinib, dasatinib, bosutinib, and ponatinib) and other interventions such as interferon-α, hydroxyurea, and allogeneic stem cell transplant. Conclusions In patients with newly diagnosed chronic myeloid leukemia, imatinib regimens were cost effective, mostly owing to the availability of generics. Nilotinib and dasatinib were generally cost effective as second-line agents for patients who were resistant or intolerant to imatinib. Though progress has been made to better characterize the cost effectiveness of first-line and second-line chronic myeloid leukemia therapies, the paucity of published cost-effectiveness studies of third-line treatments increases the uncertainty associated with economic evaluations of later lines of therapy.
