Summary
The purpose of this study is to characterize cardiac safety of Daratumumab, Cyclophosphamide, Bortezomib, and Dexamethasone (D-VCd) treatment regimens (Arm A: immediate daratumumab + VCd treatment and Arm B: daratumumab + deferred VCd) in newly diagnosed systemic amyloid light chain (AL) amyloidosis with cardiac involvement and to identify potential mitigation strategies for cardiac toxicity (cohort 1); to characterize the pharmacokinetics of subcutaneous (SC) daratumumab, among racial and ethnic minorities, including Black or African American, with newly diagnosed AL amyloidosis treated with D-VCd (cohort 2).
Description
AL amyloidosis is a rare disorder caused by clonal plasma cells that secrete immunoglobulin light chains that misfold into insoluble amyloid. The insoluble amyloid gets deposited in vital organs which results in serious and life-threatening organ dysfunction. Daratumumab is a human immunoglobulin (IgG1K) monoclonal antibody (mAb) that binds with high affinity to a unique epitope on cluster of differentiation 38 (CD38), a transmembrane glycoprotein. It is a targeted immunotherapy directed towards tumor cells that overexpress CD38. Participants will be enrolled into 2 cohorts based on cardiac involvement at baseline for cohort 1 and racial or ethnic minority with at least one organ involved for cohort 2. This study aims to generate data on risk factors for cardiac toxicity and to evaluate the cardiac safety of the proposed treatment regimens and identify potential mitigation strategies for cardiac toxicity such as deferred VCd treatment, The study will consist of screening phase (up to 28 days) and treatment phase with up to 24 treatment cycles (each cycle is 28 days). Safety assessment will include adverse events (AEs), serious adverse events (SAEs), physical examinations, Eastern Cooperative Oncology Group (ECOG) criteria for performance status, laboratory tests and vital signs. The overall duration of the study will be up to 3 years and 8 months.
