Japanese Participants with Relapsed or Refractory Multiple Myeloma (MM)TeclistamabJapanese participants will receive Teclistamab subcutaneously (SC) at four dose levels. Cohort 1 will receive Teclistamab at Dose 1 and 2 (step-up doses) prior to first treatment dose on Day 1 followed by Dose 3 weekly (that is, on Days 1,8, and 15 of a 21-day cycle). Cohort 2 will receive Teclistamab at Dose 1 and 4 (step up doses) prior to first treatment dose on Day 1 followed by Dose 5 weekly. Cohort 3 will receive Teclistamab at Dose 1, 4, and 5 (step up doses) prior to first treatment dose on Day 1 followed by Dose 6 weekly. Cohort 4 will receive Teclistamab at Dose 1, 4, and 5 (step up doses) prior to first treatment dose on Day 1 followed by Dose 7 weekly for (2 cycles), then biweekly (cycle 3 to 6) on Days 1 and 15 and monthly (cycle 7) on Day 1 of 1 28-day cycle. In Phase 2 , participants will receive Teclistamab SC at Dose 1 and 4 (step up doses) up to 8 days prior to first treatment dose on Day 1 followed by Dose 5 on Days 1,8,15, and 22 of a 28-day cycle.
Primary Outcome Measures
NameTimeMethod
Phase 1: Number of Participants with Serious Adverse Events (SAE)Up to 1 year and 5 months

A SAE is any untoward medical occurrence that at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; is a suspected transmission of any infectious agent via a medicinal product; is medically important.

Phase 1: Number of Participants with Dose Limiting Toxicity (DLT)Up to 28 days

Number of participants with DLT will be assessed. The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.

Phase 1: Number of Participants with Adverse Events (AE)Up to 1 year and 5 months

An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non investigational) product, whether or not related to that medicinal (investigational or non investigational) product.

Phase 2: Overall response rate (ORR)Up to 1 year and 5 months

ORR is defined as the percentage of participants who have a partial response (PR) or better according to the 2016 International Myeloma Working Group (IMWG) response criteria.

Secondary Outcome Measures
NameTimeMethod
Phase 2: Number of Participants with SAEs by SeverityUp to 1 year and 5 months

Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 with the exception of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), which will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) guidelines. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death related to adverse event.

Phase 2: Change from Baseline in Health-related Quality of Life (HRQoL) (Symptoms, Functioning, and Well-being) Assessed by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) ScoreUp to 1 year and 5 months

Change from baseline in EORTC- QLQ-C30 score will be reported. The EORTC- QLQ-C30 Version 3 includes 30 items that make up 5 functional scales (physical, role, emotional, cognitive, and social), 1 global health status scale, 3 symptom scales (pain, fatigue, and nausea/vomiting), and 6 single symptom items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). The item and scale scores are transformed to a 0 to 100 scale. A higher score represents greater HRQoL, better functioning, and more (worse) symptoms.

Phase 1: Objective Response RateUp to 1 year and 5 months

Objective response will be defined as partial response (PR) or better as defined by the 2016 IMWG response criteria in multiple myeloma (MM).

Phase 1 and Phase 2: Serum Concentration of TeclistamabUp to 1 year and 5 months

Serum concentration of Teclistamab will be assessed.

Phase 1: Systemic Cytokine ConcentrationsUp to 1 year and 5 months

Cytokines concentration will be measured for biomarker assessment.

Phase 1 and Phase 2: Number of Participants with Anti-teclistamab AntibodiesUp to 1 year and 5 months

Number of participants with anti-teclistamab antibodies will be assessed.

Phase 2: Change from Baseline in EuroQol Five Dimension Five Level Questionnaire (EQ-5D-5L) ScaleUp to 1 year and 5 months

Change from baseline in EQ-5D-5L scale will be reported. The EQ-5D-5L is a generic measure of health status. EQ-5D-5L is a 5 item questionnaire that assesses 5 domains including mobility, self-care, usual activities, pain/discomfort and anxiety/depression plus a visual analog scale rating "health today" with anchors ranging from 0 (worst imaginable health state) to 100 (best imaginable health state).

Phase 2: Overall survival (OS)Up to 1 year and 5 months

OS is defined as the time from the date of first dose of study drug to the date of the participant's death. If the participant is alive or the vital status is unknown, then the participant's data will be censored at the date the participant was last known to be alive.

Phase 2: Minimal Residual Disease (MRD)-negative RateUp to 1 year and 5 months

MRD-negative rate is defined as the percentage of participants who achieved MRD-negative status to a threshold of 10\^-5 at any timepoint after initial dose of teclistamab and before disease progression or starting subsequent therapy.

Phase 2: Number of Participants with AEsUp to 1 year and 5 months

An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non investigational) product, whether or not related to that medicinal (investigational or non investigational) product.

Phase 2: Number of Participants with AEs by SeverityUp to 1 year and 5 months

Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 with the exception of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), which will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) guidelines. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death related to adverse event.

Phase 2: Number of Participants with SAEsUp to 1 year and 5 months

A SAE is any untoward medical occurrence that at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; is a suspected transmission of any infectious agent via a medicinal product; is medically important.

Phase 2: Number of Participants with Abnormalities in Clinical Laboratory Test ValuesUp to 1 year and 5 months

Number of participants with abnormalities in clinical laboratory test values of hematology, serum chemistry, and coagulation will be reported.

Phase 1 and Phase 2: Duration of Response (DOR)Up to 1 year and 5 months

DOR is defined as the duration from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease, as defined in the 2016 IMWG criteria, or death.
