This study is researching an experimental drug called REGN7945 in combination with another experimental drug called linvoseltamab, (also known as REGN5458) (each individually called a "study drug" or "study drugs" when combined). This study is the first time REGN7945 will be tested in humans. Linvoseltamab has previously been studied by itself (without other cancer drugs) in participants who had advanced multiple myeloma that returned and needed to be treated again after several other therapies had failed. The aim of the study is to see how safe, tolerable, and effective REGN7945 is when given in combination with linvoseltamab, compared with linvoseltamab alone....
