Inclusion Criteria

Current inclusion criteria as of 20/05/2024:

1. Documented multiple myeloma as defined:
1.1. Multiple myeloma diagnosis according to the International Myeloma Working Group (IMWG) diagnostic criteria
1.2. Measurable disease at screening as defined by any of the following:
1.2.1. Serum M-protein level =0.5 g/dL (central laboratory)
1.2.2. Urine M-protein level =200 mg/24 hours (central laboratory)
1.2.3. Light chain multiple myeloma without measurable M-protein in the serum or the urine: serum immunoglobulin free light chain =10 mg/dL (central laboratory), and abnormal serum immunoglobulin kappa lambda free light chain ratio
2. Relapsed or refractory disease as defined by:
2.1. Relapsed disease is defined as an initial response to prior treatment, followed by confirmed progressive disease by IMWG criteria greater than (>) 60 days after cessation of treatment
2.2. Refractory disease is defined as less than (<) 25% reduction in monoclonal paraprotein (M-protein) or confirmed progressive disease by IMWG criteria during previous treatment or less than or equal to (<=) 60 days after cessation of treatment
3. Received at least one prior line of antimyeloma therapy including a proteasome inhibitor (PI) and lenalidomide. Participants who have received only one prior line of antimyeloma therapy must be considered lenalidomide-refractory (that is, have demonstrated progressive disease by IMWG criteria on or within 60 days of completion of lenalidomide-containing regimen). Participants who have received =2 prior lines of antimyeloma therapy must be considered lenalidomide exposed
4. Documented evidence of progressive disease based on the investigator’s determination of response by the IMWG criteria on or after their last regimen
5. Have an Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2 at screening and immediately prior to the start of administration of study treatment

Exclusion Criteria

Current exclusion criteria as of 20/05/2024:

1. Contraindications or life-threatening allergies, hypersensitivity, or intolerance to study drug excipients
2. Disease is considered refractory to an anti-cluster of differentiation 38 (CD38) monoclonal antibody as defined per IMWG consensus guidelines (progression during treatment or within 60 days of completing therapy with an anti-CD38 monoclonal antibody)
3. Received prior pomalidomide therapy
4. A maximum cumulative dose of corticosteroids to =140 mg of prednisone or equivalent within the 14-day period before the first dose of the study drug
5. Known active central nervous system (CNS) involvement or exhibits clinical signs of meningeal involvement of multiple myeloma. If either is suspected, negative whole-brain magnetic resonance imaging (MRI) and lumbar cytology are required
6. Plasma cell leukaemia (per IMWG criteria) at the time of screening, Waldenström's macroglobulinemia, polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes (POEMS syndrome), or primary amyloid light chain amyloidosis
