Participant involved in study for approx. 8 years duration includes Screening Phase (complete clinical evaluation will be done), Treatment Phase (monitoring of adverse events (AEs), laboratory abnormalities and clinical response), Post-Treatment Observation Phase (disease evaluations will be done) and a Long-term Follow-up Phase (Subsequent anticancer treatment, response to subsequent treatment, date of progression and survival status will be obtained every 16 weeks).The primary hypothesis is that daratumumab in combination with CyBorD will improve the overall complete hematological response rate compared to CyBorD alone in AL amyloidosis participants. Safety will be measured by AEs, laboratory test results, electrocardiogram, vital sign measurements, physical examination, and Eastern Cooperative Oncology Group (ECOG) performance status.
