25 Teclistamab (Tecvayli) Clinical Trials Recruiting Now (June 2026): BCMA × CD3 Bispecific, MajesTEC-4 + MajesTEC-7 Phase 3, Post-Anti-CD38 RRMM, AL Amyloidosis, SubQ Administration

Last updated: June 15, 2026

📌 Why this page exists: Teclistamab (Tecvayli) is the first-in-class BCMA-targeted T-cell engager approved for multiple myeloma — the leading BCMA bispecific class, and the off-the-shelf alternative to BCMA CAR-T (cilta-cel, ide-cel). Most recruiting trials are testing earlier-line combinations, post-transplant maintenance, MRD-driven consolidation, smoldering MM early intervention, and AL amyloidosis. For the full multiple myeloma trial landscape (other BCMA bispecifics, GPRC5D, cevostamab FcRH5, CAR-T, CELMoDs, smoldering), see our multiple myeloma trials page. For the sibling GPRC5D bispecific from the same Janssen program, see our talquetamab (Talvey) page.

About Teclistamab (Tecvayli)

Drug profile:

Teclistamab (brand name Tecvayli, code JNJ-64007957, USAN teclistamab-cqyv) is a first-in-class BCMA × CD3 bispecific T-cell engager developed by Janssen Biotech / Johnson & Johnson. One arm binds BCMA (B-cell maturation antigen — a TNF-receptor superfamily member highly expressed on plasma-cell-lineage tumor cells) and the other arm binds CD3 on T cells, redirecting the patient's own T cells to attack BCMA-expressing myeloma cells. Teclistamab is administered as a subcutaneous injection with step-up dosing in cycle 1.

Why BCMA matters as a target:

BCMA is the most-validated multiple myeloma target after CD38. Three BCMA bispecific T-cell engagers are now FDA-approved (teclistamab, elranatamab / Elrexfio, linvoseltamab / Lynozyfic), alongside two BCMA CAR-T products (idecabtagene vicleucel / ide-cel / Abecma; ciltacabtagene autoleucel / cilta-cel / Carvykti) and the BCMA-directed ADC belantamab mafodotin. Teclistamab was first in class, achieved BCMA × CD3 bispecific approval on the strength of MajesTEC-1, and remains the reference benchmark — the head-to-head Phase 3 NCT07518186 against the BCMA × GPRC5D dual-bispecific JNJ-79635322 is structured around teclistamab as the active comparator.

Recruiting Trials by Setting

Phase 3 — Multiple Myeloma (4 trials)

The four Phase 3 trials below are the registrational program that will move teclistamab into earlier lines, maintenance, and define its role against the next-generation dual-bispecific:

Newly Diagnosed and Transplant Setting (Phase 1–2) (5 trials)

High-Risk Smoldering Myeloma (Early Intervention) (1 trial)

MRD-Driven Consolidation (Phase 2) (2 trials)

Late-Line / Triple-Class Refractory RRMM (3 trials)

The currently-approved setting (4+ prior lines including anti-CD38 + PI + IMiD) and adjacent triple-class refractory combinations:

Resistance and Sensitivity Mechanism (1 trial)

Administration Optimization and Real-World Safety (3 trials)

The FDA label currently requires hospitalization for cycle-1 step-up doses — the main operational bottleneck for adoption in community oncology. Three active trials are working on moving teclistamab out of the inpatient setting:

AL (Light-Chain) Amyloidosis (6 trials)

AL amyloidosis is a plasma-cell-driven disease that also expresses BCMA. Because patients are frequently too frail for autologous transplant and have organ damage that limits chemotherapy options, BCMA bispecifics are a major area of investigation — teclistamab is the most-advanced BCMA bispecific being tested:

Patient Selection and Practical Considerations

Side Effects (Teclistamab-Specific Signals)

Teclistamab shares the broader CD3-engaging bispecific class profile (CRS, ICANS, cytopenias) but carries a teclistamab-specific signal that distinguishes BCMA bispecifics from the GPRC5D class (talquetamab, etentamig):

For the infection signal in particular, it is worth asking your care team in advance about IVIG replacement schedule, prophylactic antimicrobials, vaccinations (where appropriate), and what to do for fever or respiratory symptoms — the events that drive hospitalizations and treatment interruptions in practice.

Frequently Asked Questions

What is teclistamab (Tecvayli)?

Teclistamab (brand name Tecvayli, development code JNJ-64007957, USAN teclistamab-cqyv) is a first-in-class BCMA × CD3 bispecific T-cell engager developed by Janssen Biotech / Johnson & Johnson. One arm binds BCMA (B-cell maturation antigen) — a target highly expressed on plasma-cell-lineage tumor cells — and the other binds CD3 on T cells, redirecting the patient's own T cells against BCMA-expressing myeloma cells. It received FDA accelerated approval on October 25, 2022 for adults with relapsed or refractory multiple myeloma who had received at least four prior lines of therapy including an anti-CD38 monoclonal antibody, a proteasome inhibitor, and an immunomodulatory agent. The approval was based on the Phase 1/2 MajesTEC-1 study. Teclistamab is given subcutaneously with step-up dosing in cycle 1.

What cancers is teclistamab being tested in?

Teclistamab is developed primarily for multiple myeloma and other plasma-cell disorders. The 25 recruiting trials in our corpus span newly diagnosed transplant-eligible and -ineligible MM, high-risk smoldering myeloma (REVIVE), relapsed/refractory MM after one or more prior lines, MRD-driven post-transplant consolidation and maintenance, outpatient administration, and AL (light-chain) amyloidosis (six dedicated Phase 2 trials including the newly diagnosed Mayo Stage IIIB high-risk subgroup and concurrent MM + AL). Not-yet-recruiting trials extend teclistamab into plasmablastic lymphoma, primary plasma cell leukemia (QUANTUM), and severe anti-MDA5 interstitial lung disease.

What teclistamab trials are currently recruiting?

There are 25 recruiting interventional teclistamab trials as of June 2026. The four Phase 3 trials are NCT05552222 (MajesTEC-7 — Tec-DR / Tal-DR vs DRd in newly diagnosed transplant-ineligible MM), NCT05243797 (MajesTEC-4 — teclistamab maintenance after autologous transplant), NCT06208150 (Tal-Tec arm in earlier-line RRMM post anti-CD38 + lenalidomide), and NCT07518186 (JNJ-79635322 BCMA × GPRC5D head-to-head vs teclistamab in 1–3 prior line RRMM). Newly diagnosed and transplant setting: MajesTEC-5 (NCT05695508), Tec + dara/len in elderly NDMM (NCT05572229), low-dose Tec consolidation (NCT06758375), ALTITUDE alternating Dara-RVd/Tec-RVd (NCT07099391), FITFIX FOR FRAIL (NCT07107529), Tec+Tal first-line consolidation (NCT06505369), ROTATE MRD-positive consolidation (NCT06993675), REVIVE high-risk smoldering MM (NCT06100237). Late-line / RRMM: limited-duration Tec (NCT05932680), Tec + iberdomide (NCT06465316), Tec + mezigdomide (NCT07105059), single-cell resistance mechanism study (NCT05945524). Administration: outpatient (NCT05972135), outpatient step-up plan (NCT06251076), Indian RWE safety (NCT07030517). AL amyloidosis: six trials (NCT06649695, NCT06699394, NCT06935162, NCT07079423, NCT07110844, NCT07638683).

What are the main side effects of teclistamab?

Teclistamab carries the side-effect profile of CD3-engaging bispecifics plus a teclistamab-specific signal: severe infections driven by hypogammaglobulinemia, because BCMA is expressed on normal plasma cells as well as tumor cells, so engaging T cells against BCMA depletes the antibody-producing plasma cells. Patients typically need prophylactic antimicrobials and IVIG (intravenous immunoglobulin) replacement throughout treatment. This is the patient-noticeable signal that distinguishes BCMA bispecifics from talquetamab (which has dysgeusia / skin / nail changes instead). Other side effects include cytokine release syndrome (CRS) — mostly Grade 1–2, concentrated in cycle-1 step-up doses, managed with tocilizumab — immune effector cell-associated neurotoxicity syndrome (ICANS) (less frequent than with CAR-T, generally reversible), cytopenias (neutropenia, anemia, thrombocytopenia), and injection site reactions. The FDA label requires hospitalization for the step-up doses; outpatient administration is being studied in NCT05972135 and NCT06251076.
