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

Design outcomes

Primary

MeasureTime frameDescription
Phase 1: Number of Participants with Adverse Events (AE)Up to 1 year and 5 monthsAn 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 1: Number of Participants with Serious Adverse Events (SAE)Up to 1 year and 5 monthsA 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 daysNumber 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 2: Overall response rate (ORR)Up to 1 year and 5 monthsORR 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

Phase 1: Objective Response RateUp to 1 year and 5 monthsObjective 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: Duration of Response (DOR)Up to 1 year and 5 monthsDOR 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.
Phase 1 and Phase 2: Time to Response (TTR)Up to 1 year and 5 monthsTTR is defined as the time between date of first dose of study treatment and the first efficacy evaluation that the participant has met all criteria for PR or better.
Phase 2: Very Good Partial Response (VGPR) or Better Response Rate (Stringent Complete Response [sCR]+ Complete Response [CR]+VGPR)Up to 1 year and 5 monthsVGPR or better response rate (sCR+CR+VGPR) is defined as the percentage of participants who achieve a VGPR or better response according to the 2016 IMWG response criteria.
Phase 2: Complete Response (CR) or Better Response RateUp to 1 year and 5 monthsCR or better response rate is defined as the percentage of participants who achieve a CR or better response (sCR+CR) according to the IMWG 2016 criteria.
Phase 2: Stringent Complete Response (sCR) RateUp to 1 year and 5 monthssCR rate is defined as the percentage of participants who achieve an sCR according to the IMWG 2016 criteria.
Phase 2: Progression-free Survival (PFS)Up to 1 year and 5 monthsPFS is defined as the time from the date of first dose of study drug to the date of first documented disease progression, as defined in the 2016 IMWG response criteria, or death due to any cause, whichever occurs first.
Phase 2: Overall survival (OS)Up to 1 year and 5 monthsOS 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 monthsMRD-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 monthsAn 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.

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 monthsChange 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.

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: Change from Baseline in Patient Global Impression of Severity (PGIS) ScaleUp to 1 year and 5 monthsChange from baseline in PGIS scale will be reported. The PGIS is a single item that assesses severity of the participant's health state, on a 5-point verbal rating scale (1: None, 2: Mild, 3: Moderate, 4: Severe, 5: Very Severe) at the time of completing the PRO measure. Higher score indicate greater severity.
