Cost-utility Analysis of Ambulatory Dose Escalation of Bispecific Antibodies in Multiple Myeloma.

Summary

Multiple myeloma is the second most common haematological cancer. Recent innovations have made it possible for relapsed/refractory patients to benefit from the innovative immunotherapy of bispecific antibodies. These antibodies stimulate the immune system to attack tumour cells. The treatment involves an escalating dose of three subcutaneous injections every 2 to 4 days for a total of about 10 days, followed by a weekly treatment phase. The University Hospital of Toulouse was the first centre in France to offer outpatient dose escalation for this innovative treatment. This form of treatment depends on clinical and logistical feasibility. Where appropriate, patients are treated in a conventional unit. An analysis carried out at Toulouse University Hospital suggests a response to treatment, with no increased risk of complications in the outpatient setting. Patients' quality of life may also be unaffected. In addition, given the increasing demand for care in a context of finite resources, the economic evaluation of healthcare initiatives is becoming essential if we are to maintain a high-quality healthcare system that is accessible to all.
