Linvoseltamab alone or with carfilzomib versus standard combination regimens for adults with relapsed/refractory multiple myeloma.

An Open-Label, Randomized Phase 3 Study of Linvoseltamab Monotherapy and Linvoseltamab Plus Carfilzomib Versus Standard of Care Combination Regimens in Patients With Relapsed/Refractory Multiple Myeloma

Phase 3 Interventional Regeneron Pharmaceuticals · NCT07222761

This trial tests whether linvoseltamab alone or together with carfilzomib works better than standard combination treatments for adults with relapsed or refractory multiple myeloma who have had 1–3 prior therapies.

What this trial studies

This phase 3 interventional trial compares linvoseltamab given as monotherapy or in combination with carfilzomib against several standard-of-care combination regimens in adults with relapsed/refractory multiple myeloma. Eligible participants must have had 1–3 prior lines of therapy that included lenalidomide and either a proteasome inhibitor or an anti‑CD38 antibody and must have documented progressive disease with ECOG performance status 0–2. The study measures depth and duration of response, safety and side effects, pharmacokinetics of linvoseltamab, and development of anti-drug antibodies. Patients with prior T cell–based BCMA-directed therapies are excluded.

Who should consider this trial

Good fit: Adults with relapsed or refractory multiple myeloma who have received 1–3 prior therapies (including lenalidomide and either a proteasome inhibitor or an anti‑CD38 antibody), have progressive disease, and have ECOG performance status of 0–2 are the intended participants.

Not a fit: Patients who previously received BCMA‑targeted T cell therapies (BCMA bispecifics, BiTEs, or CAR‑T) or who have plasma cell leukemia, symptomatic amyloidosis, Waldenström macroglobulinemia, or POEMS syndrome are not likely to be eligible or to benefit from this study.

Why it matters

Potential benefit: If successful, the linvoseltamab regimens could produce deeper and longer responses and potentially extend survival compared with current standard regimens.

How similar studies have performed: Other BCMA‑targeting bispecific antibodies and CAR‑T cell therapies have shown promising activity in relapsed/refractory myeloma, though the specific linvoseltamab plus carfilzomib combination is being tested here.

Eligibility criteria

Show full inclusion / exclusion criteria
Key Inclusion Criteria:

1. Participant with RRMM who received at least 1 but not more than 3 prior lines of therapy, which must have included treatment with lenalidomide and either a Protease Inhibitor (PI) or anti-CD38 monoclonal antibody
2. Eastern Cooperative Oncology Group (ECOG) performance status score ≤2
3. Confirmed progressive disease according to IMWG criteria during or after the most recent line of therapy

Key Exclusion Criteria:

1. Prior treatment with a T cell-based immunotherapy targeting BCMA, including BCMA-directed bispecific antibodies, Bispecific T-cell Engagers (BiTEs), and Chimeric Antigen Receptor (CAR) T cells. Antibody-drug conjugates targeting BCMA (eg, belantamab mafodotin) are not excluded
2. Diagnosis of plasma cell leukemia, symptomatic amyloidosis (including myeloma-associated amyloidosis), Waldenström macroglobulinemia (lymphoplasmacytic lymphoma), or POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes)
3. Known Central Nervous System (CNS) involvement of myeloma including meningeal involvement
4. History of neurodegenerative condition, Progressive Multifocal Leukoencephalopathy (PML), or CNS movement disorder
