A Phase 3 Randomized Study Comparing Teclistamab in Combination With Daratumumab SC (Tec-Dara) Versus Daratumumab SC, Pomalidomide, and Dexamethasone (DPd) or Daratumumab SC, Bortezomib, and Dexamethasone (DVd) in Participants With Relapsed or Refractory Multiple Myeloma (MajesTEC-3)

The purpose of this study is to compare the efficacy of teclistamab-daratumumab (Tec-Dara) with daratumumab subcutaneously (SC) in combination with pomalidomide and dexamethasone (DPd) or daratumumab SC in combination with bortezomib and dexamethasone (DVd) in Part 1 and to evaluate the pharmacokinetics (PK), safety, and efficacy of the Tec-Dara regimen when teclistamab is administered using a alternative dosing schedule in Part 2.


Teclistamab is a novel B-cell maturation antigen (BCMA) bispecific antibody that is being evaluated to treat participants with multiple myeloma, an incurable malignant plasma cell disorder. The primary hypothesis of this study is that Tec-Dara will significantly improve progression free survival (PFS) compared with investigator's choice of DPd/DVd in participants with relapsed refractory multiple myeloma. Approximately 560 participants will be randomly assigned in a 1:1 ratio to receive either Tec-Dara (Arm A) or investigator's choice of DPd/DVd (Arm B) in Part 1 and approximately 70 participants will be enrolled in Part 2. The study will be conducted in 3 phases: Screening Phase, Treatment Phase, and Follow-up Phase. Participants will be treated until disease progression, unacceptable toxicity, or other reasons to discontinue the study. Disease evaluation will occur every cycle. Safety will be assessed throughout the study. Efficacy will be assessed using International Myeloma Working Group (IMWG) criteria. The overall duration of the study will be approximately 5 years.

Inclusion Criteria

Documented multiple myeloma as defined by the criteria: a. multiple myeloma diagnosis according to the International Myeloma Working Group (IMWG) diagnostic criteria, b. measurable disease at screening as defined by any of the following: 1) serum M-protein level greater than or equal to (>=) 0.5 gram per deciliter (g/dL); or 2) urine M-protein level >=200 milligrams (mg)/24 hours; or 3) serum immunoglobulin free light chain >=10 mg/dL and abnormal serum immunoglobulin kappa lambda free light chain ratio
Received 1 to 3 prior line(s) of antimyeloma therapy including a proteasome inhibitor (PI) and lenalidomide; a. participants who have received only 1 line of prior line of antimyeloma therapy must be lenalidomide refractory. Stable disease or progression on or within 60 days of the last dose of lenalidomide given as maintenance will meet this criterion
Documented evidence of progressive disease based on investigator's determination of response by IMWG criteria on or after their last regimen
Have an eastern cooperative oncology group (ECOG) performance status score of 0, 1, or 2 at screening and prior to the start of administration of study treatment
Have clinical laboratory values within the specified range

Exclusion Criteria

Contraindications or life-threatening allergies, hypersensitivity, or intolerance to any study drug or its excipients. Additional exclusion criteria pertaining to specific study drugs include
A participant is not eligible to receive daratumumab subcutaneous (SC) in combination with pomalidomide and dexamethasone (DPd) as control therapy if any of the following are present: 1) Contraindications or life-threatening allergies, hypersensitivity, or intolerance to pomalidomide, 2) Disease that is considered refractory to pomalidomide per IMWG
A participant is not eligible to receive daratumumab SC in combination with bortezomib and dexamethasone (DVd) as control therapy if any of the following are present: 1) Contraindications or life-threatening allergies, hypersensitivity, or intolerance to bortezomib, 2) Grade 1 peripheral neuropathy with pain or Grade >= 2 peripheral neuropathy as defined by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0, 3) Disease that is considered refractory to bortezomib per IMWG, 4) Received a strong cytochromes P450 (CYP3A4) inducer within 5 half-lives prior to randomization
Received any prior B cell maturation antigen (BCMA)-directed therapy
Has disease that is considered refractory to an anti-cluster of differentiation 38 (CD38) monoclonal antibody per IMWG
Received a cumulative dose of corticosteroids equivalent to >=140 mg of prednisone within 14 days before randomization
Received a live, attenuated vaccine within 4 weeks before randomization
Plasma cell leukemia at the time of screening, Waldenström's macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes), or primary amyloid light chain amyloidosis
