What's the purpose of this trial?

The purpose of this research study is to learn whether the combination of daratumumab SC ( Darzalex Faspro), lenalidomide (Revlimid), bortezomib (Velcade) and dexamethasone works in treating smoldering multiple myeloma and preventing progression to active or symptomatic multiple myeloma.

This trial is currently open and accepting patients.

  • 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

Published Results

Phase II Trial of Daratumumab, Bortezomib, Lenalidomide and Dexamethasone in High-Risk Smoldering Multiple Myeloma

December 10, 2023

At the time of data cut off in May 2023, 38 patients have been enrolled to part 1 with a median follow up of 18 months. The median age is 62 years old (range 36-77) with 23 females (61%) and 15 males (39%). The median plasmacytosis of enrolled patients was 20%, with median M-protein of 2.17 g/dL and median FLC ratio of 8.1. Twenty-four patients (62%) had at least one high-risk FISH abnormality (fifteen with 1q gain, four with t(4;14), one with t(14;16) and one with del 17p). Eight patients (21%) had more than one high-risk FISH abnormality.

Most common grade 3 toxicities included neutropenia (13%), ALT increased (8%), and diarrhea (8%). Upper respiratory infections occurred in 61% of patients but were mostly low-grade (COVID-19 infection in 11 patients, 1 with grade 3). No patients discontinued therapy due to toxicity.

Of the 35 patients that completed at least 2 cycles of therapy, the ORR is 100% with 43% CR, 34% VGPR and 17% PR with responses deepening over time. Seventy-seven percent of patients achieved VGPR or greater. MRD was evaluable in 22 patients at 6 m­­onths with MRD negativity rate of 59% and 14% at thresholds of 10-5 and 10-6, respectively. At 12 months, 20 patients were MRD-evaluable with 65% and 20% achieving MRD negativity at 10-5and 10-6, respectively. Of the 10 MRD-evaluable patients at 24 months, 60% were MRD negative at 10-5 and 40% at 10-6. No patients have progressed on treatment. Stem cell collection was successful in all eligible patients with average stem cell yield of 5.53 x 106 CD34+ cells/kg.
