Linvoseltamab with pre-dose Tocilizumab to reduce CRS in adults with relapsed/refractory multiple myeloma

Official title: A Phase 4, Single-Arm, Multicenter Study of Prophylactic Tocilizumab in Participants With Relapsed/Refractory Multiple Myeloma Treated With Linvoseltamab in the Outpatient Setting

Run by Regeneron Pharmaceuticals · NCT07609940 · Data updated 2026-11-12

This study tests whether giving tocilizumab before the first dose of linvoseltamab can lower the risk of cytokine release syndrome in adults with relapsed/refractory multiple myeloma who have had at least four prior therapies.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with RRMM who progressed after at least four prior lines of therapy, including a proteasome inhibitor, an IMiD, and an anti-CD38 antibody, and who have ECOG ≤2.

Probably not a fit

Patients without risk of CRS reduction from pre-dose tocilizumab or those not fitting the eligibility criteria may not experience benefit.

What this trial studies

This Phase 4 trial investigates safety, tolerability, and preliminary effectiveness of linvoseltamab given after pre-treatment with tocilizumab in adults with relapsed or refractory multiple myeloma. Participants have received at least four prior lines of therapy, including a proteasome inhibitor, an IMiD, and an anti-CD38 antibody. The study aims to understand the impact of the pre-dose tocilizumab on CRS incidence and related healthcare needs, as well as other side effects and overall tolerability. Additional questions address whether corticosteroids or extra tocilizumab doses are needed and how these practices affect safety outcomes. The trial is conducted at multiple U.S. centers with Regeneron as lead sponsor.

Why it matters

Potential benefit: If successful, the approach could reduce CRS risk and improve the safety of linvoseltamab for patients with heavily pretreated multiple myeloma.

How similar studies have gone: Prior bispecific antibody strategies have shown CRS risks; pre-medication approaches are being explored, with some evidence suggesting potential safety benefits but requiring confirmation in this context.
