A Study of Linvo-VR vs DVRd in Transplant-Eligible Adult Participants With Newly Diagnosed Multiple Myeloma (NDMM) (LINKER-MM8)

February 19, 2026 updated by: Regeneron Pharmaceuticals

A Phase 2/3, Open-Label, Randomized Study of Linvoseltamab, Bortezomib and Lenalidomide (Linvo-VR) With and Without Autologous Stem Cell Transplantation (ASCT) Vs Daratumumab, Bortezomib, Lenalidomide and Dexamethasone (DVRd) in Transplant-Eligible Participants With Newly Diagnosed Multiple Myeloma

This study is focused on participants with Newly Diagnosed Multiple Myeloma (NDMM) who are eligible for high dose chemotherapy followed by Autologous Stem Cell Transplantation (ASCT).

This study is evaluating a drug called linvoseltamab in combination with standard therapies for multiple myeloma called bortezomib (V) and lenalidomide (R). This combination is abbreviated as Linvo-VR.

The aim of this study is to compare how well Linvo-VR, with and without ASCT, treats myeloma to how well the current standard of care regimen for NDMM treats myeloma. That current standard of care regimen includes the drugs daratumumab (D), bortezomib (V), lenalidomide (R), and dexamethasone (d). This combination is referred to as DVRd. The study is also evaluating if Linvo-VR treats myeloma well enough that ASCT is no longer needed with the first myeloma treatments.

The study is looking at several other research questions, including:

  • What side effects may happen from taking linvoseltamab
  • How much linvoseltamab is in the blood at different times
  • Whether the body makes antibodies against the linvoseltamab (which could make the drug less effective or could lead to side effects)
