Inclusion Criteria:
Participants must satisfy the following criteria to be enrolled in the study:

immunoglobulin kappa lambda free light chain ratio

1. at least 3 prior MM regimens for Arm A Cohort 1 and Arm B
2. at least 1 but no greater than 3 prior MM regimens for Arm A Cohort 2 and Arm C.
- Arm A Cohort 1 and Arm B: Participant has received prior treatment with an
immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody-containing
regimen for at least 2 consecutive cycles.
- Arm A Cohort 2 and Arm C: Participant has received prior treatment with an
immunomodulatory agent for at least 2 consecutive cycles.
- Evidence of PD during or within 6 months (measured from the last dose of any drug
within the regimen) of completing treatment with the last antimyeloma regimen before
study entry.
- Participant achieved a response (minimal response [MR] or better) to at least 1 prior
treatment regimen.
- Participant has an Eastern Cooperative Oncology Group (ECOG) performance status of 0
or 1.
Exclusion Criteria:
The presence of any of the following will exclude a participant from enrollment:

part of their most recent antimyeloma treatment regimen (Arm C Cohort 1).
- Prior exposure to POM in combination with BTZ with or without dexamethasone (PV± d as
part of their most recent antimyeloma treatment regimen (Arm C Cohort 2).
- Previous history of an allogeneic hematopoietic stem cell transplantation, treatment
with any gene therapy-based therapeutic for cancer, investigational cellular therapy
for cancer or BCMA targeted therapy.
- Treatment Arm A Cohort 1 and Arm B: participant has received autologous stem cell
transplantation (ASCT) within 12 weeks prior to leukapheresis.
- Treatment Arms A Cohort 2 and Arm C: participant has received autologous stem cell
transplantation (ASCT) within 12 months prior to leukapheresis.
