3. A prior diagnosis of multiple myeloma with documented disease progression in need of treatment at time of screening;
4. Double refractory to an IMiD and a PI (regardless of the number of prior lines of therapy), or have received at least 3 prior lines of therapy including an IMiD and a PI (the definition of refractory includes intolerance to an IMiD/PI after at least two 28-day cycles of therapy);
5. Measurable disease defined as any of the following:
• Serum monoclonal protein = 0.5 g/dL by serum protein electrophoresis (SPEP)
• = 200 mg/24hr of monoclonal protein in the 24-hour urine collection by electrophoresis (UPEP)
• Serum free light chain (SFLC) = 10 mg/dL AND abnormal serum kappa to lambda free light chain (FLC) ratio
6. Life expectancy of = 6 months;
7. ECOG performance status = 2. (Patients with lower performance status based solely on bone pain secondary to multiple myeloma may be eligible following consultation and approval of the Medical Monitor);
8. Ability to understand the purpose and risks of the study, ability to participate in all the procedures required by the protocol and provide signed and dated informed consent;
9. 12-lead Electrocardiogram (ECG) with QT interval calculated by Fridericia Formula (Q-TcF) interval of = 470 msec;
10. Adequate organ function with the following laboratory results during screening (within 21 days) and immediately before study treatment administration on Cycle 1 Day 1:
• Absolute neutrophil count (ANC) = 1,000 cells/mm3 (1.0 x 109/L) (Growth factors cannot be used within 10 days (14 days for pegfilgrastim) prior to initiation of study treatment)
37
• Platelet count = 75,000 cells/ mm3 (75 x 109/L) (without transfusions during the 10 days prior to initiation of therapy)
• Hemoglobin = 8.0 g/dL (RBC transfusions are permitted)
• Total Bilirubin = 1.5 x upper limit of normal (ULN), except patients diagnosed with Gilbert’s syndrome that have been reviewed and approved by the Medical Monitor
• AST (SGOT) and ALT (SGPT) = 3.0 x ULN
• Renal function: Estimated creatinine clearance by Cockcroft- Gault formula of = 45 mL/min
11. Must have or be willing to have an acceptable central catheter. (Port A cath, peripherally inserted central catheter (PICC) line, or central venous catheter);
12. a) Male patients: Male patient that agrees to use contraception during the treatment period and for at least 3 months after the last dose of study treatment and refrain from donating sperm during this period.
b) Female patients: A female patient is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
iii. Not a woman of childbearing potential (WOCBP)
or
iv. A WOCBP who agrees to follow the contraceptive guidance during the treatment period and for at least 3 months after the last dose of study treatment

1. Primary refractory disease (i.e. never responded with at least MR to any prior therapy);
2. If treated with daratumumab or another anti-CD38 antibody: Refractory to treatment or failure to achieve at least PR as best response;
3. Prior treatment with CD38 CAR-T cell therapy or CD38/CD3 bispecific antibodies;
4. Chronic obstructive pulmonary disease (COPD) with a Forced Expiratory Volume in 1 second (FEV1) less than 50% of predicted normal;
5. Moderate or severe persistent asthma within the past 2 years, or currently has uncontrolled asthma of any classification;
6. Evidence of mucosal and/or internal bleeding or platelet transfusion refractory (platelet count fails to increase by > 10,000 cells/mm3 after a transfusion of an appropriate dose of platelets);
7. Any medical conditions that, in the Investigator’s opinion, would impose excessive risk to the patient or would adversely affect his/her participating in this study. Examples of such conditions are: a significant history of cardiovascular disease (e.g., heart failure class III or IV according to New York Heart Association (NYHA), cardiac angioplasty or stenting, myocardial infarction, unstable angina, significant cardiac conduction system abnormalities, uncontrolled hypertension, = Grade 3 thromboembolic event in the last 6 months);
8. Known active infection that is uncontrolled or has required intravenous systemic therapy within 14 days of randomization. Patients that has required oral anti-infective treatment within 14 days of randomization should be discussed with the Medical Monitor;
9. Other malignancy diagnosed or requiring treatment within the past 3 years with the exception of adequately treated basal cell carcinoma, squamous cell skin cancer, carcinoma in-situ of the cervix or breast or very low and low risk prostate cancer in active surveillance;
10. Serious psychiatric illness, active alcoholism, or drug addiction that may hinder or confuse compliance or follow-up evaluation;
11. Human immunodeficiency virus or active hepatitis C viral infection, either known or if detected during screening;
12. Hepatitis B: both active (defined as HBsAg+) or non-active hepatitis B (defined as HBsAg-, Anti-HBs+, Anti-HBc+):
• Patients with prior hepatitis B vaccine are permitted (defined as HBsAg-, Anti-HBs+, Anti-HBc-).
13. Concurrent known or suspected amyloidosis or plasma cell leukemia;
14. POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes);
15. Known CNS or meningeal involvement of myeloma:
16. Any of the following treatments, within the specified timeframe:
• Previous cytotoxic therapies, including cytotoxic investigational agents, for multiple myeloma within 3 weeks (6 weeks for nitrosoureas) prior to initiation of therapy.
• The use of live vaccines within 30 days before initiation of therapy.
• IMiDs, PIs and or corticosteroids within 2 weeks prior to initiation of therapy.
• Other investigational therapies and mAb within 4 weeks of initiation of therapy.
