Can a Pre-Dose prevent a dangerous reaction in multiple myeloma treatment?
NCT ID NCT07609940
First seen Jun 24, 2026 · Last updated Sep 11, 2026 · Updated 6 times
Summary
This study tests whether giving tocilizumab before the first dose of linvoseltamab can lower the risk of cytokine release syndrome (CRS) in people with relapsed or refractory multiple myeloma. The 30 participants have already tried at least four prior treatments. Researchers will monitor CRS severity, hospital visits, and side effects to see if this approach is safe and effective.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tocilizumab and linvoseltamab
- What this could lead to
- If it works, this could make a new multiple myeloma treatment safer by reducing a serious side effect called cytokine release syndrome.
- What could go wrong
- This is a small, early-phase study with only 30 participants, so results may not apply to everyone. The approach may not reduce side effects as hoped.
