What's the purpose of this trial?
The primary purpose of the study is to investigate whether early treatment with the study drug can prevent the development of multiple myeloma. This requires understanding the safety and tolerability of the study drug (how your body reacts to linvoseltamab) as well as the effectiveness of the study drug (how well linvoseltamab eliminates plasma cells and prevents the development of multiple myeloma). All participants will start treatment with gradually increasing doses of linvoseltamab (step-up doses) before they start receiving the assigned full dose. The study is split into 2 parts.
* In Part 1, separate groups of 3-6 patients will receive different full doses of linvoseltamab to evaluate the short-term side effects (safety) observed within the first 35 days after starting treatment, to make sure the study drug is well tolerated, and to help make a decision about the dosing regimens chosen for Part 2.
* In Part 2, a larger number of participants will be randomized to different dosing regimens to further assess the side effects of linvoseltamab, and to evaluate the ability of linvoseltamab to treat HR-MGUS and NHR-SMM and prevent progression to multiple myeloma.
The study is looking at several other research questions, including:
* How many participants treated with linvoseltamab (study drug) 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 your 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)
This is an upcoming trial that has not yet started accepting patients.
