Clinical trials

This study is researching a drug called REGN17372 used with another drug called linvoseltamab (each individually called "study drug" or "study drugs" when combined) in participants with relapsed (when a tumor comes back) or refractory (when a tumor does not respond to treatment) multiple myeloma.

The aim of the study is to understand if REGN17372 can be given safely with linvoseltamab, and if so, what dosing regimen should be used for this treatment combination, in comparison with linvoseltamab alone. The study is looking at: * What side effects may happen from taking REGN17372 with linvoseltamab * How well REGN17372 and linvoseltamab, or linvoseltamab alone, work in treating multiple myeloma * What is the best dose of REGN17372 when given with linvoseltamab * How much study drug(s) are in the blood at different times * Whether the body makes antibodies against the study drugs (which could make the study drugs less effective or could lead to side effects) * If and how REGN17372 and linvoseltamab affect the overall quality of life, daily activities, symptoms and treatment side effects based on participant own feedback (Phase 2)
