Detailed Description
-----------------
The purpose of this research study is to learn whether the combination of daratumumab (Darzalex Faspro), lenalidomide (Revlimid), bortezomib (Velcade) and dexamethasone works in treating smoldering multiple myeloma and preventing progression to active or symptomatic multiple myeloma. This combination of drugs are considered investigational which means it has not been approved in this combination for smoldering myeloma by the United States Food and Drug Administration. The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits The names of the study drugs involved in this study are: Daratumumab (also called Darzalex Faspro) Bortezomib (also called Velcade) Lenalidomide (also called Revlimid) Dexamethasone Participants may be treated for up to 24 months and will be followed for up to 3 years. It is expected that about 30 people will take part in this research study. This research study is a Phase II clinical trial, which tests the effectiveness of an investigational drug(s). The investigational drugs used in this research study are daratumumab (Darzalex Faspro), lenalidomide (Revlimid), bortezomib (Velcade) and dexamethasone. Investigational means that the FDA (the U.S. Food and Drug Administration) has not approved the combination of daratumumab (Darzalex Faspro), lenalidomide (Revlimid), bortezomib (Velcade) and dexamethasone as a treatment regimen for the specific disease.

AST≤ 3 x institutional upper limit of normal (ULN) ALT ≤ 3 x institutional upper limit of normal (ULN) Estimated creatinine clearance≥ 60mL/min or a creatinine ≤ 2.2 mg/dL Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care. Females of childbearing potential* must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10 - 14 days and again within 24 hours prior to prescribing lenalidomide for Cycle 1 (prescriptions must be filled within 7 days as required by Revlimid REMS®) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking lenalidomide. -- A female of childbearing potential is a sexually mature female who: has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time during the preceding 24 consecutive months) All study participants must be registered into the mandatory Revlimid REMS® program and be willing and able to comply with the requirements of the REMS® program. Females of child-bearing potential must adhere to the scheduled pregnancy testing as required in the Revlimid REMS® program. Men must agree to use a latex condom during sexual contact with a female of childbearing potential even if they have had a successful vasectomy Detectable clonality sequence by next generation sequencing using clonoSEQ assay to allow for minimal residual disease measurement Ability to understand and the willingness to sign a written informed consent. Exclusion Criteria: Symptomatic Multiple Myeloma or any evidence of CRAB criteria, including presence of myeloma defining events (MDE). Any prior therapy for active Myeloma should also be excluded. Prior therapy for smoldering myeloma is not an exclusion criterion. Bisphosphonates are not excluded Other concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered investigational. Prior therapy with bisphosphonate is allowed. Prior radiation therapy to a solitary plasmacytoma is allowed. Prior clinical trials or therapy for smoldering MM or MGUS are allowed but should be discussed with the Principal Investigator. Serious medical or psychiatric illness likely to interfere with participation in this clinical study. Diagnosed or treated for another malignancy within 2 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in-situ malignancy, or low-risk prostate cancer after curative therapy. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. Pregnant or nursing women will be excluded from the study because lenalidomide is an agent with the potential for teratogenic or abortifacient effects. History of allergic reactions attributed to compounds of similar chemical or biologic composition to daratumumab, bortezomib, lenalidomide, or hyaluronidase Known seropositive for or active viral infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV) or SARS-CoV-2 (COVID-19). Patients who are seropositive because of hepatitis B virus vaccine are eligible. Patients who are positive for SARS-COV-2 antibody, HIV1 and 2 antibody, hepatitis B core antibody or hepatitis B surface antigen must have a negative polymerase chain reaction (PCR) result before enrollment. Those who are PCR positive will be excluded. Subject has known chronic obstructive pulmonary disease (COPD) or severe, persistent asthma with a Forced Expiratory Volume in 1 second (FEV1) < 50% of predicted normal. Note that PFT/FEV1 testing is required at screening for patients suspected of having COPD or severe, persistent asthma or are suspected of having those conditions or other respiratory impairment

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of high risk smoldering multiple myeloma (SMM) patients who are MRD negative (MRD-) | MRD negative disease (MRD-) is defined as zero residual sequence cells detected at a level of one million cells. At time of final analysis, the 2-year MRD- rate will be summarized as a proportion with a 90% exact binomial confidence interval | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective Response Rate | (partial response or better according to the modified IMWG criteria) and the proportion of patients with a MRD, CR, PR or MR will be reported by Arm with 90% exact binominal confidence interval (CI). | 2 Years | 
| Duration of Response | time from objective response to disease progression or death, or date last known progression-free and alive for those who have not progressed or died). The Kaplan-Meier method will be used. | 2 Years | 
| Progression-free survival | (time from protocol therapy initiation to the disease progression or death from any cause, censored at date last known progression free for those who have not progressed or died). The Kaplan-Meier method will be used. | 2 Years | 
| Number of Participants with Treatment Related Adverse Events as Assessed by CTCAE v4.0 | For toxicity reporting, all adverse events and laboratory abnormalities will be graded and analyzed using CTCAE version 4 | 2 Years |
