ABSTRACT
Novel therapies for multiple myeloma (MM) have improved patient survival, but their high costs strain healthcare budgets. End-of-life phases of treatment are generally the most expensive, however, these high costs may be less justifiable in the context of a less pronounced clinical benefit. To manage drug expenses effectively, detailed information on end-of-life drug administration and costs are crucial. In this retrospective study, we analysed treatment sequences and drug costs from 96 MM patients in the Netherlands who died between January 2017 and July 2019. Patients received up to 16 lines of therapy (median overall survival: 56.5 months), with average lifetime costs of 209 871 (3111/month; range: 3942-776 185) for anti-MM drugs. About 85% of patients received anti-MM treatment in the last 3 months before death, incurring costs of 20 761 (range: 70-50 122; 10% of total). Half of the patients received anti-MM treatment in the last 14 days, mainly fully oral regimens (66%). End-of-life treatment costs are substantial despite limited survival benefits. The use of expensive treatment options is expected to increase costs further. These data serve as a reference point for future cost studies, and further research is needed to identify factors predicting the efficacy and clinical benefit of continuing end-of-life therapy.

INTRODUCTION: Acute myeloid leukemia (AML) is the most common type of acute leukemia in adults, but the results for patients with AML are still unsatisfactory. The discovery of new mutations in AML, including IDH mutations, has opened the door for treatment with targeted agents. Ivosidenib is a selective, potent inhibitor of the IDH1 mutant protein. AREAS COVERED: This review summarizes the mechanism of action, safety profile and efficacy of ivosidenib for patients with IDH1-mutated AML. The authors then provide their expert perspectives on the use of the drug including their future perspectives. EXPERT OPINION: Ivosidenib is a promising, most probably practice changing, new drug for the treatment of IDH1-mutated AML. Current phase III trials are ongoing to evaluate the addition of ivosidenib to the current standards-of-care. In the near future, more drug combinations are awaited. Challenges for the future include the development of resistance and establishing the duration of maintenance therapy.
