A Study of Gammagard Liquid (Immune Globulin Infusion, 10%) to Prevent Infections in Adults With Multiple Myeloma
A Multicenter, Randomized, Controlled, Open-label, Group-Sequential, Phase 3 Study to Investigate the Efficacy, Safety, and Tolerability of Intravenous Gammagard Liquid (Immune Globulin Infusion, 10%) for Primary Infection Prophylaxis Compared With Secondary Infection Prophylaxis in Adult Subjects With Multiple Myeloma Receiving B-Cell Maturation AntigenxCD3-Directed Bispecific Antibody Therapy

Brief Summary
Multiple myeloma is a cancer of the plasma cells in the bone marrow. The main aim of this study is to learn how well the Immune Globulin Infusion (human), 10 percentage (%) (IGI, 10%) can help prevent infections in participants with multiple myeloma receiving B-cell maturation antigen (BCMA) x cluster of differentiation 3 (CD3) directed bispecific antibody therapy. Participants will be randomly assigned to one of two groups:
- 1.Primary infection prevention group: They will receive IGI, 10% for 12 months.
- 2.Secondary infection prevention group: They will only receive IGI, 10% if they develop a serious infection during the 12 months study period.

Study Arms (2)
Primary Infection Prophylaxis: IGI, 10%
EXPERIMENTALParticipants randomized to primary infection prophylaxis will receive a 400 milligrams per kilogram (mg/kg) dose of IGI, 10% in accordance with the standard of care (SOC), intravenously (IV) every 3 or 4 weeks within 3 days after randomization up to 12 months.
Secondary Infection Prophylaxis: IGI, 10%
ACTIVE COMPARATORParticipants randomized to secondary infection prophylaxis will receive a 400 mg/kg dose of IGI, 10% in accordance with the SOC, IV every 3 or 4 weeks only after experiencing at least one serious infection, as determined by the investigator, for the remainder of the 12 months observational period.
Interventions
IGI, 10% IV infusion.
Eligibility Criteria
You may qualify if:
- The participants must have a documented diagnosis of Multiple Myeloma (MM) according to the guidelines by the International Myeloma Working Group (IMWG) before enrollment.
- Participant who recently started teclistamab monotherapy within the first 8 weeks of their planned treatment schedule and are planned to receive teclistamab for the next 12 months.

- The participant is at least 18 years of age at the time of signing the ICF.
- If a person of childbearing potential engages in sexual relations that carry risk of pregnancy, they agree to the following for the period from screening until 30 days after the last dose of study drug:
- To use a highly effective contraceptive method.
- To avoid donating ova.
You may not qualify if:
- The participant has not achieved at least a minimal response to teclistamab during the screening period after signing the ICF and within 8 weeks of the first step-up dose of teclistamab.
- The participant has a current serious infection or greater than (\>) 1 serious infection in the past 3 months before screening.
- The participant has a documented polyclonal IgG level less than (\<) 150 milligrams per deciliter (mg/dL) at the most recent assessment before teclistamab initiation (within 4 weeks) as assessed by the investigator according to the site's standard practice.
- The participant is currently receiving immunoglobulin products or has received immunoglobulin products within 16 weeks before screening.
- The participant has received a hyperimmune or specialty high-titer immunoglobulin product (example, cytomegalovirus immune globulin, varicella-zoster immune globulin, hepatitis B immune globulin) within 30 days before screening.
- The participant has received live viral vaccines within 30 days before screening.
- The participant has an Eastern Cooperative Oncology Group performance status score of \>2.
- The participant has an active viral or bacterial infection or symptoms/signs of such an infection requiring treatment with anti-infectives within 1 week before enrollment.
- The participant has received other B Cell Maturation Antigen (BCMA)\*Cluster of Differentiation (CD3)-directed Bispecific Antibody therapy (BsAb), BCMA-targeted chimeric antigen receptor T-cell (CAR T-cell), or BCMA-targeted antibody drug conjugate (ADC) therapy within 1 year prior to screening.
- The participant is scheduled to undergo plasmapheresis during the course of study or has undergone plasmapheresis in the last 16 weeks before screening.
- The participant may be excluded from the study if, in the opinion of the investigator, the participant is at high risk for symptomatic hyperviscosity syndrome.
- The participant has major surgery scheduled during the study, or the participant has not fully recovered from a recent major surgery (as judged by the investigator) during screening (participants with planned surgical procedures to be conducted under local anesthesia may participate).
- The participant has an active secondary (non-MM) malignancy or other medical condition with life-expectancy of less than (\<) 2 years.
- The participant has a known history of hypersensitivity or persistent reactions (urticaria, breathing difficulty, severe hypotension, or anaphylaxis) after Intravenous Immunoglobulin (IVIG) and/or immune serum globulin infusions.
- The participant has a known history or current diagnosis of thromboembolic episodes such as deep vein thrombosis, pulmonary embolism, myocardial infarction, ischemic stroke, transient ischemic attack, peripheral artery disease within 6 months before screening.
