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.

Induction: 16 mg/kg actual body weight IV weekly (weeks 1-8; total of 8 doses) then every 2 weeks (weeks 9-24; total of 8 doses). Consolidation: 16 mg/kg actual body weight IV every four weeks (weeks 25-36) Maintenance: 16 mg/kg actual body weight IV every eight weeks (weeks 37-88) Sites will continue to use IV daratumumab to treat existing study patients until the IV daratumumab stock on site has been exhausted. The sites will then transition existing patient to SQ daratumumab. New patients will be started on SQ 1800mg daratumumab. Induction- Cycles 1-2 (days 1, 8,15, 22), Cycles 3-6 (Weeks 9-24- two weeks (days 1, 15 ) Consolidation- Every 4 weeks on day 1 Maintenance- Every 8 weeks on day 1
Induction: 25 mg PO once daily, on days 1-21 of each 28-day cycle (weeks 1-24) Consolidation: 25 mg PO once daily, on days 1-21 of each 28-day cycle (weeks 25-36) Maintenance: 10 mg PO once daily, on days 1-21 of each 28-day cycle until progression or intolerance Maintenance: 10 mg PO once daily, on days 1-21, weeks 37+ until progression
Consolidation: 1.5 mg/m2 SQ on day 1, 8, 15 and 22 of each 28-day cycle (weeks 25-36)
Induction and Consolidation: 40 mg (or reduced dose of 20 mg) PO or IV weekly

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.
Time frame: At the end of week 36 (post-consolidation therapy)
Overall Survival (OS)
Time from initiation of daratumumab-based combination regimen until death or last follow-up date (whichever occurs first).
Time frame: Up to 3 years after start of study treatment
Progression-free Survival (PFS)
Time from initiation of daratumumab-based combination regimen to disease progression, where disease progression is according to the IMWG criteria, death, or last disease evaluation before the start of any subsequent anti-myeloma therapy (whichever occurs first).
Time frame: Up to 3 years after start of study treatment
Proportion of Participants Who Were MRD-positive After Induction and Subsequently Achieve MRD-negative After Consolidation.
Of participants who are still MRD-positive after induction, proportion that achieve MRD-negative after consolidation. Per IMWG Response Criteria
Time frame: At the end of week 36 (post-consolidation therapy)
Proportion of Participants Who Maintain Post-induction MRD-negativity to Post-consolidation
Of participants who achieve post-induction MRD-negativity, proportion that maintain MRD-negativity through completion of consolidation therapy.
Time frame: At the end of week 36 (post-consolidation therapy)
Proportion of Participants Who Maintain Post-induction MRD-negativity to Post-consolidation.
Of participants who achieve post-induction MRD-negativity, proportion that maintain MRD-negativity through completion of 1 year of maintenance therapy.
Time frame: At the end of week 88 (post 1 year of maintenance therapy)
Proportion of Participants Who Maintain Post-induction MRD-negativity to Last Follow-up Visit.
Of participants who achieve post-induction MRD-negativity, proportion that maintain MRD-negativity until last follow-up visit (if after week 88).
Time frame: After week 88, up to 3 years after start of study treatment
Health-related Quality of Life Assessment Changes From Baseline Using EuroQol Survey "EQ-5D."
EQ-5D is a standardized participant-reported outcome measure developed by the EuroQol Group and used in this trial to assess health-related quality of life.
Time frame: Baseline to 16 weeks post-last-dose of study treatment (Dara, R, V or d)
Neurotoxicity Assessment Changes From Baseline Using Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) Questionnaire.
The FACT/GOG-Ntx is a patient-reported outcome measure used to assess health-related quality of life in patients undergoing cancer therapy, plus an eleven-item subscale (Ntx subscale) that evaluates symptoms and concerns associated specifically with chemotherapy-induced neuropathy.
Time frame: Baseline to 16 weeks post-last-dose of study treatment (Dara, R, V or d)
Incidence of Treatment-emergent Adverse Events
Toxicity will be assessed according to the NCI Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.
Time frame: From start of study treatment (Dara-Rd) up to 30 days post last dose of study treatment (Dara, R, V or d)
Proportion of Participants With a Successful Stem Cell Mobilization After Receiving Dara-based Induction Therapy.
Of participants who have stem cells collected, proportion who have enough CD34+ cells after mobilization to be able to proceed with an autologous stem cell transplant (ASCT) if needed. Successful mobilization for each participant will be based on standard criteria at the institution where the transplant will be administered.
Time frame: At the end of week 24 (post-induction therapy)
