Phase 2 Study With Minimal Residual Disease (MRD) Driven Adaptive Strategy in Treatment for Newly Diagnosed Multiple Myeloma (MM) With Upfront Daratumumab-based Therapy

Study Overview
=================
Brief Summary
-----------------
This phase 2 trial will test whether the combination of DaraRd (daratumumab + lenalidomide + dexamethasone) as induction therapy, followed by DRVd (daratumumab + lenalidomide + bortezomib + dexamethasone) consolidation therapy, if needed, will result in more patients achieving minimal residual disease (MRD)-negative status, relative to the standard of care. Consolidation therapy will be administered only to those patients with MRD-positive status after induction therapy. This is a study based on adaptive design for decision making of treatment options. Duration of therapy (daratumumab cycles) will depend on individual approach, response, evidence of disease progression and tolerance.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of participants who achieve MRD negativity either after induction or, if still MRD-positive after induction, after consolidation. | Of participants who complete at least one cycle of induction therapy, proportion that achieve MRD-negativity after completion of induction + those who achieve MRD-negativity after completion of consolidation (if still MRD-positive after induction). MRD status determined by International Myeloma Working Group (IMWG) Response Criteria. | At the end of week 36 (post-consolidation therapy) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
