The purpose of this study is to evaluate the clinical benefit of subcutaneous (SC) daratumumab administered in combination with standard multiple myeloma (MM) regimens in participants with MM as measured by overall response rate (ORR) or very good partial response (VGPR) or better rate.

The hypothesis is that the addition of daratumumab administered SC to standard MM regimens
will improve responses compared to response data observed in completed phase 3 studies
without daratumumab. Disease evaluations will include measurements of myeloma proteins, bone
marrow examinations, skeletal surveys, assessment of extramedullary plasmacytomas, and
measurements of serum calcium corrected for albumin. Safety will be measured by adverse
events, laboratory test results, electrocardiogram (ECGs), vital sign measurements, physical
examination findings, SC injection-site assessments, and assessment of Eastern Cooperative
Oncology Group (ECOG) performance status score. Study will consist of 3 phases (screening,
treatment and follow-up) and duration of study is approximately 3 years.
