Multiple Myeloma Clinical Trial
Phase II Study of the CD38 Antibody Daratumumab in Patients With High-Risk MGUS and Low-Risk Smoldering Multiple Myeloma
This research study is studying a drug as a possible treatment for Monoclonal Gammopathy of Unknown Significance (MGUS) or Smoldering Multiple Myeloma (SMM).
The drug involved in this study is:
This research study is a Phase II clinical trial, which tests the effectiveness of an investigational drug. Preliminary experience suggests that daratumumab may prevent or postpone SMM from becoming active multiple myeloma. The purpose of this research study is to determine if the this drug may improve the rate of prevention of multiple myeloma.
Multiple myeloma is a cancer of the plasma cell, which is an important part of the immune system. Patients with active multiple myeloma generally require treatment. There are currently no approved therapies for smoldering multiple myeloma or Monoclonal Gammopathy of Unknown Significance.
Daratumumab is a drug that may kill or stop cancer cells from growing through a variety of mechanisms by attaching to the CD38 molecule, which is over-expressed in multiple myeloma cells. This type of drug is called a monoclonal antibody. The FDA (the U.S. Food and Drug Administration) has not approved Daratumumab for the participant specific disease but it has been approved for use in active Multiple Myeloma.
Age ≥ 18 years
Must meet criteria for high-risk MGUS or low-risk smoldering myeloma as described below:
Must have <10% plasma cells and <3.0g/dL M-spike and at least 2 of the following 3 criteria:
Abnormal free light-chain (FLC) ratio (<0.26 or >1.65)
M-protein concentration (≥1.5 g/dL)
Non-IgG M protein (including IgA)
Low-Risk Smoldering Multiple Myeloma
Must only present with 1 of the following criterion:
Monoclonal Protein ≥ 3 g/dL
---≥ 10% Bone Marrow Plasma Cells
FLC ratio < 0.125 or > 8
-No evidence of CRAB criteria† or new criteria of active MM which including the following:
Increased calcium levels (corrected serum calcium >0.25 mmol/dL above the upper limit of normal or >0.275 mmol/dL)
Renal insufficiency (attributable to myeloma)
Anemia (Hb 2 g/dL below the lower limit of normal or <10 g/dL)
Bone lesions (lytic lesions or generalized osteoporosis with compression fractures)
No evidence of the following new criteria for active MM including the following: Bone marrow plasma cells >60%, Serum involved/uninvolved FLC ratio ≥100, and MRI with more than one focal lesion
Participants with CRAB criteria that are attributable to conditions other than the disease under study may be eligible
ECOG Performance Status (PS) 0, 1, or 2 (Appendix A)
The following laboratory values obtained ≤ 21 days prior to registration:
ANC ≥ 1000/uL
PLT ≥ 50,000/uL
Total bilirubin ≤ 2.0 mg/dL (If total is elevated check direct and if normal patient is eligible.)
AST ≤ 3 x institutional upper limit of normal (ULN)
ALT ≤ 3 x institutional upper limit of normal (ULN)
Creatinine ≤ 2 mg/dL or Creatinine Clearance ≥ 40 mL/min
Ability to understand and the willingness to sign an 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.
Female patients who are postmenopausal for at least 1 year before the screening visit or are surgically sterile are eligible. Females of childbearing potential (as defined below) may also be eligible but must have a negative serum or urine pregnancy test with a sensitivity of at least 25 mIU/mL within 21 days of registration.
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)
---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)
Any prior therapy for symptomatic Multiple Myeloma or smoldering Multiple Myeloma should also be excluded, including prior use of IMIDs, proteasome inhibitors, or CD138 inhibitors. Prior therapy for smoldering Multiple Myeloma with agents that are not therapeutically active against MM is not an exclusion criterion.
Other concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered investigational. Prior therapy with bisphosphonates is allowed. Prior radiation therapy to a solitary plasmacytoma is allowed.
Concurrent exposure to any commercially available agents known to be active against SMM and MM.
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.
Subject has known chronic obstructive pulmonary disease (COPD) with a Forced Expiratory Volume in 1 second (FEV1) < 50% of predicted normal.
Note that FEV1 testing is required for patients suspected of having COPD and subjects must be excluded if FEV1 <50% of predicted normal.
Subject has known moderate or severe persistent asthma within the past 2 years or currently has uncontrolled asthma of any classification.
Subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed in the study
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrollable cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Pregnant or nursing women will be excluded from the study.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to Daratumumab.
Known seropositive for or active viral infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV). Patients who are seropositive because of hepatitis B virus vaccine are eligible. Patients who are positive for 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.
Major surgery within 4 weeks before enrollment.
Subject is known or suspected of not being 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.
Vaccination with live attenuated vaccines within 4 weeks of first study agent administration
Subject has clinically significant cardiac disease, including significant ischemic coronary disease, congestive heart failure (New York Heart Association [NYHA] Class III or IV), unstable arrhythmias, myocardial infarction or unstable angina within 6 months before randomization, a history of additional risk factors for torsades de pointes (eg, electrolyte abnormalities, family history of Long QT Syndrome), or a family history of sudden cardiac death before age 40.
Participation in other therapeutic clinical trials, including those with other investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial
