443 Treatment experience and symptom burden in multiple myeloma: interim results of a longitudinal electronic patient-reported outcomes study

OBJECTIVES/GOALS: Patients with multiple myeloma (MM) experience significant disease- and treatment-related symptom burden, especially with higher lines of therapy (LOT). We used a remote symptom monitoring app to characterize overall symptom profile, symptom bother, and quality of life (QOL) among patients with MM across LOT and longitudinally. METHODS/STUDY POPULATION: We used Carevive PROmpt, a symptom monitoring app for cancer patients. From 11/10/22 to 9/27/23, we enrolled 84 adult patients with MM of any stage and anywhere in the treatment continuum from Duke Health MM clinics. Participants received weekly symptom surveys while on active treatment. Per prior studies, we defined heavily pretreated patients as those on current LOT ≥4. Our sample had a mean (SD) age of 63.7 (10.8) years and was 56.0% male; 73.8% had a prior bone marrow transplant, 40.5% were on LOT ≥4 (53.6% on LOT
