Participant with diagnosed RRMM (as per IMWG definitions or investigator's discretion) who have received at least 3 prior lines of therapy including a proteasome inhibitor, an anti-CD 38 antibody and an immunomodulatory agent and have demonstrated disease progression on the last therapy
Documented evidence of progressive disease on last line of therapy based on investigator's determination of response by IMWG response criteria
