About
This research study aims to evaluate the safety and effectiveness of the combination of isatuximab, pomalidomide, and dexamethasone (Isa-Pd) for the treatment of relapsed or refractory multiple myeloma (RRMM), which refers to multiple myeloma that has returned or has not responded to prior treatment. The study will specifically investigate the impact of administering lower-than-standard doses of pomalidomide and dexamethasone. Using lower doses of pomalidomide and dexamethasone in this setting has not been approved by the Food and Drug Administration (FDA).
Full description
This study aims to address the challenges faced in selecting appropriate therapy for elderly or highly toxicity-vulnerable patients who are poor candidates for standard (full-dose) chemotherapy regimens. Traditional clinical trials often exclude these patients, limiting the generalizability of available data. This single-arm multicenter phase II study will enroll 49 older and/or toxicity-vulnerable patients with RRMM. The study will evaluate the safety and effectiveness of isatuximab when used in combination with pomalidomide and dexamethasone at lower than standard doses. The primary objective is to estimate the overall response rate (ORR), while secondary objectives include the estimation of additional measures of response, as well as measures of toxicity and tolerability. All participants in the trial will also be evaluated by Cancer and Aging Research Group Geriatric Assessments (CARG-GA) and patient- reported outcome (PRO) measures of quality of life (QOL). Biomarkers of aging and frailty will also be studied.
Duration of therapy:
The duration of study participation will depend on the response to the treatment. In the absence of treatment delays due to adverse events, treatment with Isa-Pd will generally continue until disease progression, unacceptable side effects, other illness or condition that prevents further study treatment, or a subject's decision to withdraw from the study. On average, subjects will most likely be treated for approximately 10 months on this study.
Duration of Follow-Up:
All participants, including those withdrawn for adverse events (AEs) will be followed after removal from study treatment until death or full subject withdrawal from the study for other reasons. Participants removed from the study treatment for unacceptable AEs will be followed for resolution or stabilization of the AEs.
