cost-utility analysis of home-based versus hospital-based chemotherapy in multiple myeloma: case of carfilzomib

Conditions: Multiple Myeloma

Summary: carfilzomib is administered in treatment of multiple myeloma intravenously on two consecutive days, each week for three weeks (days 1, 2, 8, 9, 15, and 16), followed by a 12-day rest period (days 17 to 28). with covid pandemic, the investigators had to limit patient visits to the hospital. the treatment protocols were modified by switching to weekly injections of carfilzomib according to the pleiades and arrow 2 studies. considering the frequency of intravenous (iv) administration, home-based chemotherapy in hospital-at-home (hah) setting is an attractive and suitable alternative to standard hospital-based chemotherapy in outpatient-hospital (oh), and is expected to provide both cost-savings for the health insurance (hi) and improvement in patient quality of life (qol). the purpose of the study is to assess the cost-utility of home-based compared to hospital-based carfilzomib administration in multiple myeloma. the investigators are also planning on assessing healthcare resource utilization and related costs, adverse and intercurrent events, and patients' quality of life and satisfaction, for each strategy.

all participants receive the first cycle of treatment in oh. they are then randomized between exclusive oh treatment and combined treatment in oh and at home with hah services. for the hah group, the first injection of each cycle is delivered in oh. the rest of the cycle is delivered at home by hah after a clinical examination (by nurse or general practitionner). primary and secondary endpoints are collected at day 1 of cycle 3, 6, 9, 12, 18 and one month after the end of treatment. participants we leave the protocol prematurely in case of treatment failure, toxicity or if participant ask to. for those patients, the end of study visit will be done one month after ending treatment.
