Summary: The main purpose of this study is to see if IgPro20 can prevent infection in people with multiple myeloma (MM) who have hypogammaglobulinemia from receiving bispecific monoclonal antibodies (BsAbs).
Eligibility:

Inclusion Criteria:

- Diagnosis of RRMM receiving a commercially available bispecific antibody

- Received at least 1 but no more than 4 cycles of BsAb

- Received 2 or more lines of therapy for MM IgG ≤ 4 g/L excluding paraprotein. For IgG Kappa MM, hypogammaglobulinemia will be determined by subtracting the M spike from IgG

- Males or females greater than or equal to 18 years old at the time of consent

- ECOG ≤ 3

- Life expectancy > 12 months

Exclusion Criteria:

- HSCT within 3 months before enrollment

- Planned CAR-T therapy in the next 6 months

- >1 major (deep-seated) infection within the preceding 3 months

- HIV infection, Active HCV, or Active HBV infection

- Pregnancy

- Neutrophils < 500 x 10^9 per mL, Platelets < 30 x 10^9 per mL

- History of cancer other than MM in the last 3 years requiring active chemotherapy or radiation

- Known reaction/allergy to IgG products

- Intracranial hemorrhage or embolic CVA in the last 6 months

- Hyperproteinemia

- Protein-losing enteropathy

- Creatinine Cl <30 ml/min

- Documented progression on BsAb

- Known history of Hyperprolinemia

- On current or previous IVIG (in the last 3 months)
