Recruitment & Eligibility

Status: ot Recruiting

Sex: All

Target Recruitment: 38

Inclusion Criteria

Documented diagnosis of multiple myeloma (MM) according to International Myeloma Working Group (IMWG) diagnostic criteria

- Participant must have measurable disease defined by any of the following: Serum M-protein level greater than or equal to (>=) 1.0 gram per deciliter (g/dL); Urine M-protein level >= 200 milligrams per 24 hours (mg/24 hours); or Light chain MM, for participants without measurable disease in the serum or urine: serum Ig-free light chain (FLC) >=10 milligrams per deciliter (mg/dL) and abnormal serum Ig kappa-lambda FLC ratio; or if central laboratory assessments are not available, relevant local laboratory measurements must exceed the minimum required level by at least 25 percent (%)

- Participant must be relapsed or refractory to established therapies with known clinical benefit in relapsed/refractory MM or be intolerant to established MM therapies and a candidate for teclistamab treatment in the opinion of the treating physician. Prior lines of therapy must include a proteasome inhibitors (PI), an immunomodulatory drug (IMiD), and an anti-CD38 antibody in any order during the course of treatment. Participants who could not tolerate PI, immunomodulatory drugs, or anti-CD38 antibody are allowed

- Eastern Cooperative Oncology Group (ECOG) performance status grade of 0 or 1 at screening and immediately before the start of study treatment administration

- Woman of childbearing potential must have a negative pregnancy test at screening and within 24 hours prior to the first dose of study treatment using highly sensitive pregnancy test either serum (beta-human chorionic gonadotropin [beta-hCG]) or urine

Exclusion Criteria

- Prior treatment with any B cell maturation antigen (BCMA)-targeted therapy

- Toxicities from previous anticancer therapies that have not resolved to baseline levels or to less than or equal to (<=) Grade 1 except for alopecia or peripheral neuropathy

- Received a cumulative dose of corticosteroids equivalent to >=140 mg of prednisone within the 14-day period before the first step-up dose of study treatment (does not include pretreatment medication)

- Stem cell transplantation: An allogeneic stem cell transplant within 6 months. Participants who received an allogeneic transplant must be off all immunosuppressive medications for 6 weeks without signs of graft-versus-host disease; Received an autologous stem cell transplant less than or equal (<=) 12 weeks before the first step-up dose of study treatment

- Central nervous system involvement or clinical signs of meningeal involvement of MM. If either is suspected, whole brain magnetic resonance imaging (MRI) and lumbar cytology are required during screening
