This study is researching an investigational drug called linvoseltamab ("study drug") inparticipants at moderate risk of developing multiple myeloma (about 3 to 10% averageannual risk), a group that consists of patients with precancerous conditions calledHigh-Risk Monoclonal Gammopathy of Undetermined Significance (HR-MGUS) and Non-High-RiskSmoldering Multiple Myeloma (NHR-SMM).The primary purpose of the study is to understand how well the study drug can eliminateabnormal plasma cells and laboratory signs of HR-MGUS and NHR-SMM.The study is looking at several other research questions, including: - How many participants treated with linvoseltamab have improvement of their HR-MGUS or NHR-SMM? - What side effects may happen from taking the study drug? - How much study drug is in the blood at different times? - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects).
