A Study to Assess Safety of Teclistamab in Indian Participants With Relapsed and Refractory Multiple Myeloma

Prior treatment

• Received any prior B cell maturation antigen (BCMA)-directed therapy
• Stroke, transient ischemic attack, or seizure within 6 months prior to screening
• Participant had major surgery or had significant traumatic injury within 2 weeks prior to enrollment, or will not have fully recovered from surgery, or has major surgery planned during the time the participant is expected to be treated in the study

Other

• Participants who are not eligible to receive teclistamab as per the locally approved prescribing information
• Central nervous system (CNS) involvement or clinical signs of meningeal involvement of multiple myeloma. If either is suspected, negative whole brain MRI, and lumbar cytology are required

• 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
• Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
• Contraceptive use by female participants should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. A female participant is eligible to participate if she is not pregnant or breastfeeding, and not a woman of child bearing potential (WOCBP) or is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of less than \[\<\] 1 percent \[%\] per year), preferably with low user dependency, during the treatment period and for a period of 6 months after the last dose of study treatment and agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during study period
• A WOCBP must have a negative highly sensitive serum pregnancy test within 24 hours before the first dose of study treatment
