What this trial studies

This phase III trial evaluates three different three-drug induction regimens followed by maintenance therapy for patients with newly diagnosed multiple myeloma who are not candidates for stem cell transplantation. The study focuses on frail or intermediate-fit patients, assessing the effectiveness of various drug combinations including bortezomib, lenalidomide, dexamethasone, and daratumumab. The primary objectives include comparing progression-free survival and overall survival among the different treatment arms, as well as evaluating safety and quality of life. Participants will be monitored for response rates and potential complications such as venous thromboembolism.

Who should consider this trial

Good fit: Ideal candidates are adults with newly diagnosed multiple myeloma who are considered frail or intermediate-fit and not suitable for stem cell transplantation.

Not a fit: Patients with multiple myeloma who are fit for stem cell transplantation or have advanced disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide more effective treatment options for frail patients with multiple myeloma, improving their survival and quality of life.

How similar studies have performed: Other studies have shown promising results with similar drug combinations in treating multiple myeloma, indicating potential for success in this approach.

    * Note: growth factor and transfusion utilization are allowed if cytopenias are considered secondary to bone marrow involvement from MM)
* For Participants Meeting "Frail" Status:

  * Absolute neutrophil count (ANC) \>= 0.75 x10\^9/L (must be performed within 28 days prior to registration)

    * Note: growth factor and transfusion utilization are allowed if cytopenias are considered secondary to bone marrow involvement from MM)
* For Participants Meeting "Intermediate Fit" Status, one or more of the following criteria must be present:

  * Kidney dysfunction showing calculated creatinine clearance (CrCl) \<30 ml/min.

    * Actual lab serum creatinine value with a minimum of 0.7 mg/dL.
  * Participants must have bone marrow function assessed and meet the below criteria ranges:

    * Hemoglobin between 7-8 g/dL, OR
    * Platelets between 50-75 x10\^9/L, OR
    * ANC between 0.75-1 x10\^9/L

* Participants must have whole body imaging within 60 days prior to registration. The recommended method of imaging is a positron emission tomography/computed tomography (PET/CT); a low-dose whole body CT scan or whole-body magnetic resonance imaging (MRI) or skeletal survey should be done only if a PET/CT scan cannot be done or is non-feasible. This must be documented in the comments section of the Onstudy form.

  * An emergency use of a short course of corticosteroids (equivalent of dexamethasone 160 mg) any time before registration, or
  * Up to one complete cycle of a non-daratumumab and hyaluronidase-fihj containing anti-myeloma regimen (1 cycle = 21 or 28 days depending on the regimen being used), or

Uncontrolled blood pressure: systolic blood pressure (SBP) \> 140 mmHg or diastolic blood pressure (DBP) \> 90 mmHg. Participants are permitted to be receiving multiple anti-hypertensive medications (unless otherwise indicated in the study). All blood pressure measurements within the 14 days prior to registration must be SBP =\< 140 and DBP =\< 90. A participant with a single blood pressure elevation who upon rechecking has a normal blood pressure will remain eligible at the discretion of the registering investigator.
* Participants must not have a prior or concurrent malignancy whose natural history or treatment (in the opinion of the treating physician) has the potential to interfere with the safety or efficacy assessment of the investigational regimen.
* Participants must not be pregnant or nursing. Individuals who are of reproductive potential must have agreed to use an effective contraceptive method with details provided as a part of the consent process. A person who has had menses at any time in the preceding 24 consecutive months or who has semen likely to contain sperm is considered to be of "reproductive potential." In addition to routine contraceptive methods, "effective contraception" also includes refraining from sexual activity that might result in pregnancy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) including hysterectomy, bilateral oophorectomy, bilateral tubal ligation/occlusion, and vasectomy with testing showing no sperm in the semen.
