- Dose Limiting Toxicity (DLT) [ Time Frame: Up to Day 28 ]The Dose Limiting Toxicities (DLTs) are based on drug related adverse events and defined as any of the following events: hematological / non hematological toxicity of Grade 3 or higher.
- Number of Participants With Adverse Events (AEs) as a Measure of Safety and Tolerability [ Time Frame: Up to 7 years and 3 months ]An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
- Teclistamab Serum Concentrations [ Time Frame: Up to 8 weeks ]Concentration assessment will be done to evaluate the effect of Teclistamab.
- Number of Participants with Teclistamab Antibodies [ Time Frame: Up to 8 weeks ]Antibodies to Teclistamab will be assessed to evaluate potential immunogenicity.
- Preliminary Antitumor Activity of Teclistamab at the RP2D(s) in Part 2 [ Time Frame: Up to End of Treatment (Approximately 91 days) ]Preliminary antitumor activity of Teclistamab will be done using the International Myeloma Working Group (IMWG) response criteria.
- Biomarker Assessment [ Time Frame: Up to 8 weeks ]Biomarker assessment may be done to evaluate the effect of Teclistamab.

Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Documented diagnosis of multiple myeloma according to International Myeloma Working Group (IMWG) diagnostic criteria

- Female participants of childbearing potential must use acceptable method of contraception
- Participants must sign an ICF indicating that he or she understands the purpose of and procedures required for the study and is willing to participate in the study. Consent is to be obtained prior to the initiation of any study-related tests or procedures that are not part of standard-of-care for the participant's disease
Exclusion Criteria:
- Prior treatment with any B cell maturation antigen (BCMA) targeted therapy
- Prior antitumor therapy as follows, before the first dose of study drug: Targeted therapy, epigenetic therapy, or treatment with an investigational drug or used an invasive investigational medical device within 21 days or at least 5 half-lives, whichever is less; Monoclonal antibody treatment for multiple myeloma within 21 days; Cytotoxic therapy within 21 days; Proteasome inhibitor therapy within 14 days; Immunomodulatory agent therapy within 7 days; Gene modified adoptive cell therapy (example, chimeric antigen receptor modified T cells, natural killer [NK] cells) within 3 months; Radiotherapy within 14 days or focal radiation within 7 days
- Toxicities from previous anticancer therapies that have not resolved to baseline levels or to Grade 1 or less except for alopecia or peripheral neuropathy
- Received a cumulative dose of corticosteroids equivalent to >= 140 milligram (mg) of prednisone within the 14-day period before the first dose of study drug (does not include pretreatment medication)
- Known active central nervous system (CNS) involvement or exhibits clinical signs of meningeal involvement of multiple myeloma
