17 Talquetamab (Talvey) Clinical Trials Recruiting Now (June 2026): GPRC5D × CD3 Bispecific, MonumenTAL-3, Tal-DR Newly Diagnosed, Post-BCMA Sequencing, SubQ Administration

Last updated: June 14, 2026

📌 Why this page exists: Talquetamab (Talvey) is the first-in-class GPRC5D-targeted T-cell engager approved for multiple myeloma, opening a non-BCMA target class for patients whose disease has relapsed after BCMA-directed therapy. Most recruiting trials are testing earlier-line combinations, post-BCMA sequencing, and subcutaneous administration. For the full multiple myeloma trial landscape (BCMA bispecifics, GPRC5D, cevostamab FcRH5, CAR-T, CELMoDs, smoldering), see our multiple myeloma trials page.

About Talquetamab (Talvey)

Drug profile:

Talquetamab (brand name Talvey, code JNJ-64407564, USAN talquetamab-tgvs) is a first-in-class GPRC5D × CD3 bispecific T-cell engager developed by Janssen Biotech / Johnson & Johnson. One arm binds GPRC5D (G-protein coupled receptor class C group 5 member D — an orphan GPCR 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 GPRC5D-expressing myeloma cells. Talquetamab is administered as a subcutaneous injection with step-up dosing in cycle 1, on either a weekly or every-other-week schedule depending on the regimen.

Why GPRC5D matters as a target:

Before talquetamab, all approved CD3-engaging bispecifics in multiple myeloma targeted BCMA (teclistamab, elranatamab, linvoseltamab). GPRC5D is the first non-BCMA target class to reach approval, which matters clinically because patients whose disease progresses on a BCMA bispecific or BCMA CAR-T need a target outside that class to respond. Talquetamab — and the broader GPRC5D class (etentamig; the BCMA × GPRC5D dual-bispecific JNJ-79635322 now in Phase 3) — is what makes that sequencing possible. The FcRH5 × CD3 bispecific cevostamab, now in Phase 3, is the second non-BCMA, non-GPRC5D target class entering MM.

Recruiting Trials by Setting

Phase 3 — Earlier-Line RRMM and Newly Diagnosed MM (2 trials)

The two Phase 3 trials below are the registrational program that will determine whether talquetamab moves out of the 4+ prior line setting into earlier lines of therapy. Both are sponsored by Janssen.

Newly Diagnosed and Transplant Setting (Phase 2) (6 trials)

Late-Line / Triple-Class Refractory RRMM (Phase 1/2) (4 trials)

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

Post-BCMA Sequencing (2 trials)

A critical practical question in 2026 MM care — what comes after a BCMA bispecific or BCMA CAR-T? Talquetamab (a non-BCMA target) is one of the leading sequencing options:

Extramedullary Disease (1 trial)

Administration Optimization and Supportive Care (2 trials)

Trials Not Yet Recruiting

Note: a single non-oncology talquetamab Phase study in refractory generalized myasthenia gravis (NCT07499323) is also Not Yet Recruiting; we list it here for transparency but it is outside the scope of this oncology page.

Patient Selection and Practical Considerations

Side Effects (Talquetamab-Specific Signals)

Talquetamab has a distinct side-effect profile that reflects where GPRC5D is normally expressed — in addition to plasma cells, GPRC5D is present on keratinized tissues (skin, nail, tongue). These talquetamab-specific signals are different from the BCMA bispecific class (teclistamab, elranatamab, linvoseltamab):

For the patient-noticeable side effects in particular (taste, skin, nails), it is worth asking your care team in advance about supportive care expectations and dose-modification options — these are the events that drive treatment breaks or schedule changes in practice.

Frequently Asked Questions

What is talquetamab (Talvey)?

Talquetamab (brand name Talvey, development code JNJ-64407564, USAN talquetamab-tgvs) is a first-in-class GPRC5D × CD3 bispecific T-cell engager developed by Janssen Biotech / Johnson & Johnson. One arm binds GPRC5D — an orphan G-protein coupled receptor highly expressed on plasma-cell-lineage tumor cells — and the other binds CD3 on T cells, redirecting the patient's own T cells against GPRC5D-expressing myeloma cells. It received FDA accelerated approval on August 9, 2023 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 MonumenTAL-1 study. Talquetamab is given subcutaneously with step-up dosing in cycle 1.

What cancers is talquetamab being tested in?

Talquetamab is being developed almost exclusively for multiple myeloma and related plasma-cell disorders. GPRC5D is an orphan G-protein coupled receptor with highly restricted expression — mainly on plasma cells (malignant and normal), keratinized tissues (skin, nail, tongue), and a few other tissues. Outside multiple myeloma, talquetamab is being studied in one early trial in refractory generalized myasthenia gravis (NCT07499323), but oncology development is focused on plasma-cell malignancies. The 17 recruiting trials in our corpus span newly diagnosed MM (transplant-eligible and -ineligible), smoldering myeloma, relapsed/refractory MM after one or more prior lines, post-BCMA sequencing, post-stem-cell-transplant maintenance, extramedullary disease, and preventive management of GPRC5D-related oral side effects.

What talquetamab trials are currently recruiting?

There are 17 recruiting interventional talquetamab trials as of June 2026. The two Phase 3 trials are NCT06208150 (Tal-P or Tal-Tec vs investigator's choice EPd / PVd in RRMM after anti-CD38 + lenalidomide) and NCT05552222 (Tec-DR / Tal-DR vs DRd in transplant-ineligible newly diagnosed MM). Newly diagnosed and transplant setting: MajesTEC-5 (NCT05695508), OPTIMMAL post-ASCT maintenance (NCT06461988), Tal+Tec consolidation (NCT06505369), ROTATE MRD-positive consolidation (NCT06993675), FITFIX FOR FRAIL (NCT07107529), REVIVE high-risk smoldering myeloma (NCT06100237). Late-line / RRMM: MonumenTAL-1 (NCT04634552, still recruiting at the recommended Phase 2 dose), Talq + iberdomide + dex (NCT06348108), MAGENTA mezigdomide + talquetamab (NCT07032714), subcutaneous talquetamab in elderly early relapse (NCT06827860). Post-BCMA sequencing: talquetamab after BCMA CAR-T ide-cel (NCT06066346), Cilta-Talq Fusion (NCT07093554). Specialized: EBRT + talquetamab for extramedullary disease (NCT06572605), outpatient administration (NCT05972135), and a Phase 2 trial of preventive treatments for GPRC5D-related dysgeusia (NCT06500884).

What are the main side effects of talquetamab?

Talquetamab has a distinct side-effect profile that reflects where GPRC5D is normally expressed — in addition to plasma cells, GPRC5D is on keratinized tissues (skin, nail, tongue). The most talquetamab-specific (and patient-noticeable) events are dysgeusia (taste changes / taste loss), skin changes (rash, dry skin, palmar-plantar desquamation), and nail changes. These are distinct from BCMA bispecifics (teclistamab, elranatamab) — common enough that a dedicated Phase 2 trial (NCT06500884) is testing preventive treatments for GPRC5D-related oral events. Like other CD3 bispecifics, talquetamab also carries a cytokine release syndrome (CRS) risk (mostly Grade 1–2, concentrated in cycle 1 step-up doses), and a smaller risk of immune effector cell-associated neurotoxicity syndrome (ICANS). Infections (including opportunistic infections) and cytopenias are also possible. The FDA label requires hospitalization for the step-up doses; outpatient administration is being studied in NCT05972135.
