real world insights during treatment for relapsed/refractory multiple myeloma with isatuximab

Conditions: Multiple Myeloma; Refractory Multiple Myeloma

Summary: this descriptive study aims to evaluate the experience of adults with relapsed or refractory multiple myeloma receiving standard of care isatuximab-irfc through collection of quantitative, qualitative and wearable data. fifty adults with relapsed or refractory multiple myeloma receiving standard of care isatuximab-irfc will be enrolled across 2 sites, the university of california san francisco and the university of texas md anderson cancer center. consented participants will be enrolled in a 3-month digital health coaching program through which electronic patient reported outcomes and wearable activity data will be collected. outcomes include treatment experience, quality of life, financial toxicity, treatment adherence, symptom burden and health self-efficacy. these will be captured by patient reported outcome measures including the patient's qualitative assessment of treatment- real world (pqat-rw), patient global impression of change/severity (pgic/s), european organization for research and treatment of cancer quality of life questionnaire (eortc-qlq-c30), quality of life questionnaire multiple myeloma (qlq-my20), and the european qol-5 dimensions (eq5d), cancer behavior inventory-brief form (cbi-b), center for adherence support evaluation (case) medication adherence index, comprehensive score for financial toxicity (cost) instrument. clinical data, including treatment history, healthcare utilization, and co-morbidities, as well as demographic data will be collected via the electronic health record from each clinical site. this data will be complemented by qualitative data from a selected cohort of study participants with a focus on treatment experience ranging from infusion burden, toxicity management, to overall quality of life. evaluation of this data in combination will be used to better understand the treatment experience of individuals on standard of care isatuximab-irfc specifically, and with relapsed or refractory multiple myeloma generally, contributing to an existing gap in the literature regarding patient reported outcomes from diverse data sources. outcomes will be analyzed with attention to the relationship between social determinants of health, including race, ethnicity, and geographic location, and treatment experience as reflected in both the qualitative and quantitative data.


Eligibility criteria:
inclusion criteria: * age 18 or older * diagnosis of relapsed/refractory multiple myeloma corresponding to the food and drug administration (fda) package insert for isatuximab-irfc (sarclisa®). * confirmed or planned treatment with intravenous isatuximab-irfc for relapsed/refractory multiple myeloma as standard-of-care therapy. concurrent therapy with other agents (e.g., pomalidomide) is allowed. * access to and willingness to use a smartphone or other device through which they can send and receive text messages, emails and/or access a mobile application. * willingness to wear and have data collected by a fitbit * ability to engage in physical activity as evidenced by an eastern cooperative oncology group (ecog) performance status score of less than or equal to 2 exclusion criteria: * individuals who are terminally ill, defined as individuals identified by their physician as likely having 6 months or less to live, or those individuals transitioned to comfort measures only (meaning only supportive care measures without curative focused treatment) * individuals for whom there is documentation of inability to provide consent in the medical record. * individuals receiving isatuximab-irfc subcutaneously
