- Subjects must have adequate hepatic function laboratory values ≤ 14 days prior to registration:
- Aspartate aminotransferase (AST), alkaline phosphatase (AP) or alanine aminotransferase (ALT) ≤ 3 × the upper limit of normal (ULN)
- Total bilirubin ≤ 1.5 x ULN except for patients with a history of elevated total bilirubin, such as in Gilbert's.
- Hepatic Child-Pugh score at worse A (patients are eligible for the phase 2 part but not for the Run-in-Period of the trial).
- Female patients will have to satisfy the following criteria:
- Be postmenopausal for at least 1 year Prior to registration visit, OR
- Be surgically sterile, OR

- Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence \[e.g., calendar, ovulation, symptothermal, post-ovulation methods\] and withdrawal are not acceptable methods of contraception). If patient is female and of childbearing potential, she must have a negative serum beta human chorionic gonadotropin (β-HCG) test \< 14 days prior to registration and consent to ongoing pregnancy testing during the course of the study.
- Male patients, even if surgically sterilized (i.e., status post-vasectomy), must agree to one of the following
- Practice effective barrier contraception during the entire study treatment period and through 90 days after the last dose of study drug, OR
- Practice true abstinence when this is in line with the preferred and usual lifestyle of he subject. (Periodic abstinence \[e.g., calendar, ovulation, symptothermal, postovulation methods\] and withdrawal are not acceptable methods of contraception).
- Subjects must have the willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, study procedures, and research procedures.
Exclusion
- MGRS associated with diseases other than plasma cell dyscrasia (e.g. CLL, B-cell neoplasm, Waldenstrom's macroglobulinemia…)
- Plasma cell leukemia, AL amyloidosis, or POEMS syndrome.
- Treatment with prior drugs aimed at the plasma cell dyscrasia.
- Treatment with prior or concurrent investigational agents aimed at the plasma cell dyscrasia.
- Female patients who are lactating or have a positive serum pregnancy test during the screening period.
- Major surgery ≤ 14 days before registration.
- Focal radiation therapy within 14 days prior to registration with the exception of palliative- radiotherapy for symptomatic management but not on measurable extramedullary plasmacytoma.
- Disease-related central nervous system involvement.
- The subject has uncontrolled significant intercurrent illness including, but not limited to, ongoing or active infection.
- Clinically significant cardiac disease, including:
- Myocardial infarction within 6 months before randomization, or unstable or uncontrolled disease/condition related to or affection cardiac function (e.g., unstable angina, congestive heart failure, New York Heart Association Class III-IV)
- Uncontrolled cardiac arrhythmia
- Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol.
- Known allergy to any of the study medications, their analogues, or excipients in the various formulations of any agent.
- Concurrent malignancy except for treated non-melanoma skin cancer, cervical carcinoma in situ and low-risk prostate CA being monitored without treatment.
- Grade 2 or higher peripheral neuropathy on clinical examination during the screening period.
- Chemotherapy ≤ 14 days of registration.
- Exposure to an investigational drug (including investigational vaccine) or invasive investigational medical device for any indication within 4 weeks or 5 pharmacokinetic halflives, whichever is longer.
- Patients with known chronic obstructive pulmonary disease (COPD) with a forced expiratory volume in 1 second (FEV1) \<50% of predicted normal; moderate or severe persistent asthma within the past 2 years. Note that FEV1 testing is required for participants suspected of having COPD and participants must be excluded if FEV1 is \<50% of predicted normal
- Moderate or severe persistent asthma within the past 2 years, or uncontrolled asthma of any classification. Note that participants who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed to participate.
- Patients who have a contraindication to the use of any form of anticoagulation or antiplatelet agents.
- The use of strong CYP3A4 and CYP1A2 inducers or inhibitors will not be allowed while patients are treated on this study.
- Patients with Hepatic Child-Pugh score B and C. Note that patients with Hepatic Child-Pugh score A are excluded from the Run-in-Period of the trial
- Patient is:
- Known history of human immunodeficiency virus (HIV) and those who are seropositive for HIV.
- Seropositive for hepatitis B (defined by a positive test for hepatitis B surface antigen \[HBsAg\]). Subjects with resolved infection (ie, subjects who are HBsAg negative but positive for antibodies to hepatitis B core antigen \[anti-HBc\] and/or antibodies to hepatitis B surface antigen \[anti-HBs\]) must be screened using real-time polymerase chain reaction (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 (anti-HBs positivity as the only serologic marker) AND a known history of prior HBV vaccination, do not need to be tested for HBV DNA by PCR.
- Seropositive for hepatitis C (except in the setting of a sustained virologic response \[SVR\], defined as aviremia at least 12 weeks after completion of antiviral therapy).
- Vaccination with live attenuated vaccines within 4 weeks of first study agent administration.
- Plasmapheresis within 28 days before randomization.
