Home Based Daratumumab Administration for Patients With Multiple Myeloma

PRIMARY OBJECTIVE: I. Evaluate treatment burden (using the Cancer Treatment Satisfaction Questionnaire \[CTSQ\]). SECONDARY OBJECTIVES: I. Determine adherence to home delivery of daratumumab and hyaluronidase-fihj (darzalex faspro). II. Evaluate quality of life (using European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire \[EORTC QLQ-30\]) based on site of care (home versus \[vs.\] infusion center). III. Evaluate financial burden (using the COST survey) based on site of care (home vs. infusion center). IV. Evaluate Safety of home administration of darzalex-faspro. V. Evaluate barriers to home administration. EXPLORATORY OBJECTIVES: I. Evaluate patient perceptions of home administration of anti-neoplastic therapy. II. Evaluate opportunity cost based on site of care (home vs. infusion center) (using the Oncology Opportunity Cost Assessment Tool \[OOCAT\] survey). OUTLINE: Patients receive daratumumab and hyaluronidase-fihj subcutaneously (SC) over 3-5 minutes in the infusion center on day 1 of cycles 1, 2, 7, and 8 and at home on day 1 of cycles 3, 4, 5, and 6. Cycles repeat every 28 days for 8 cycles in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 2 months.
