Dose Expansion Cohort
Participants will receive cevostamab, intravenously (IV), in combination with elranatamab, subcutaneously (SC), with step-up dosing of each drug in pre-phase following which they will receive elranatamab, at the assigned dose as a SC injection until disease progression or unacceptable toxicity. Participants will also receive cevostamab at the assigned dose as IV infusion until disease progression or unacceptable toxicity or up to 1 year on treatment, whichever occurs first.
