Perseus: This phase III study is evaluating the effectiveness of adding targeted therapy (daratumumab) to a combined treatment of other cancer drugs (velcade and lenalidomide) and steroids (dexemethasone) in people with previously untreated multiple myelomaA Phase 3 Study Comparing Daratumumab, VELCADE (Bortezomib), Lenalidomide, and Dexamethasone (D-VRd) vs VELCADE, Lenalidomide, and Dexamethasone (VRd) in Subjects With Previously Untreated Multiple Myeloma Who Are Eligible for High-dose Therapy

Exclusion

1. Prior or current systemic therapy or stem cell transplant (SCT) for any plasma cell dyscrasia, with the exception of emergency use of a short course (equivalent of dexamethasone 40 mg/day for a maximum 4 days) of corticosteroids before treatment.
2. Peripheral neuropathy or neuropathic pain Grade 2 or higher, as defined by the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.
3. Prior or concurrent invasive malignancy (other than multiple myeloma) within 5 years of date of randomization (exceptions are adequately treated basal cell or squamous cell carcinoma of the skin, carcinoma in situ of the cervix or breast, or other non-invasive lesion that in the opinion of the investigator, with concurrence with the sponsor's medical monitor, is considered cured with minimal risk of recurrence within 3 years).
4. Radiation therapy within 14 days of randomization.
5. Plasmapheresis within 28 days of randomization.
6. Clinical signs of meningeal involvement of multiple myeloma.
7. Chronic obstructive pulmonary disease (COPD) with a Forced Expiratory Volume in 1 second (FEV1) <50% of predicted normal (for subjects ≥65 years old FEV1 <50% or diffusing capacity of the lungs for carbon monoxide [DLCO] <50%)
8. Moderate or severe persistent asthma within the past 2 years, or currently has uncontrolled asthma of any classification. (Note that subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed in the study).

9. Any of the following:

   1. Seropositive for human immunodeficiency virus (HIV)
   2. Seropositive for hepatitis B (defined by a positive test for hepatitis B surface antigen [HBsAg]). Subjects with resolved infection (ie, subjects who are positive for antibodies to hepatitis B core antigen [antiHBc] and/or antibodies to hepatitis B surface antigen [antiHBs]) must be screened using real-time PCR measurement of hepatitis B virus (HBV) DNA levels. Those who are PCR positive will be excluded. EXCEPTION: Subjects with serologic findings suggestive of HBV vaccination (antiHBs positivity as the only serologic marker) AND a known history of prior HBV vaccination, do not need to be tested for HBV DNA by polymerase chain reaction (PCR).
   3. Seropositive for hepatitis C (HCV) (anti-HCV antibody positive or HCV-RNA quantitation positive), except in the setting of a sustained virologic response (SVR), defined as viremia at least 12 weeks after completion of antiviral therapy.
10. Concurrent medical or psychiatric condition or disease (such as but not limited to, systemic amyloidosis, POEMS, active systemic infection, uncontrolled diabetes, acute diffuse infiltrative pulmonary disease) that is likely to interfere with the study procedures or results, or that in the opinion of the investigator, would constitute a hazard for participating in this study.

11. Any of the following:

    1. myocardial infarction within 6 months before randomization, or an unstable or uncontrolled disease/condition related to or affecting cardiac function (eg, unstable angina, congestive heart failure, New York Heart Association Class III-IV)
    2. uncontrolled cardiac arrhythmia or clinically significant electrocardiogram (ECG) abnormalities
    3. screening 12-lead ECG showing a baseline QT interval >470 msec
    4. left ventricular ejection fraction (LVEF) <40% for subjects age 65-70 years old
12. Received a strong CYP3A4 inducer within 5 half-lives prior to randomization
13. Allergy, hypersensitivity, or intolerance to boron or mannitol, corticosteroids, monoclonal antibodies or human proteins, or their excipients (refer to the Investigator's Brochure), or sensitivity to mammalian-derived products or lenalidomide.
14. Not able to comply with the study protocol (eg, because of alcoholism, drug dependency, or psychological disorder). Subject has any condition for which, in the opinion of the investigator, participation would not be in the best interest of the subject (eg, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments.
15. Pregnant, or breast-feeding, or planning to become pregnant while enrolled in this study or within 3 months after the last dose of any component of the treatment regimen. Or, subject is a man who plans to father a child while enrolled in this study or within 3 months after the last dose of any component of the treatment regimen.
16. Major surgery within 2 weeks before randomization or will not have fully recovered from surgery, or has surgery planned during the time the subject is expected to participate in the study. Kyphoplasty or Vertebroplasty is not considered major surgery.
17. Received an investigational drug (including investigational vaccines) or used an invasive investigational medical device within 4 weeks before randomization or is currently enrolled in an interventional investigational study.
18. Contraindications to the use of any components of the backbone treatment regimens, per local prescribing information.
19. Gastrointestinal disease that may significantly alter the absorption of oral drugs
20. Vaccination with live attenuated vaccines within 4 weeks of first study agent administration
21. Unable or unwilling to undergo antithrombotic prophylactic treatment.
