• 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 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 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.
• The participant has a documented diagnosis of a form of primary immunodeficiency (PID) involving a defect in antibody formation and requiring IgG replacement, as defined according to the International Union of Immunological Societies Committee.
• Known substance abuse including opiates, psychostimulant agents, or other illicit drugs with the exception of cannabinoids within 12 months of screening.
• The participant is receiving immunosuppressive treatment (other than for MM or corticosteroids) at screening or plans to receive immunosuppressive treatment after study enrollment.

Más betegség

• 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 an active secondary (non-MM) malignancy or other medical condition with life-expectancy of less than (<) 2 years.
• The participant has moderate to severe renal dysfunction based on an estimated glomerular filtration rate less than (<) 30 milliliters per minute per 1.73 square meters (mL/min/1.73 m\^2), as defined by kidney disease: Improving Global Outcomes Clinical Practice Guideline for the Management of Glomerular Diseases, 2021 at the time of screening.
• The participant has a known history of or is positive at screening for one or more of the following: hepatitis B surface antigen, Polymerase Chain Reaction (PCR) for hepatitis C virus, PCR for Human Immunodeficiency Virus (HIV) Type 1 and Type 2. Cured participants with a history of hepatitis C infection who have a negative PCR test at screening are eligible.
• Participant with a known systemic hypersensitivity to any of the excipients of IGI, 10% in accordance with the investigator's brochure/package insert/Summary of Product Characteristics.

Laborértékek

• 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 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 persistent serum aspartate aminotransferase and alanine aminotransferase >3.0 times the upper limit of normal (ULN) at screening (may be repeated once to determine if it is persistent).
• The participant has an immunoglobulin A (IgA) deficiency (<0.07 grams per liter [g/L]) with antibodies to IgA and a history of hypersensitivity reaction to IVIG.
• The participant has anemia that would preclude phlebotomy for laboratory studies, according to standard practice at the site, at the discretion of the investigator (may be repeated once to determine if it has resolved).
• The participant has a medical condition, laboratory finding, or physical examination finding that precludes participation or with clinical evidence of any significant acute or chronic disease that, in the opinion of the investigator, may interfere with the successful completion of the study or place the participant at undue medical risk.
