New combo therapy aims to tackle Hard-to-Treat myeloma
NCT ID NCT07455851
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 6 times
Summary
This early-phase study tests a new experimental drug, REGN17372, combined with another drug called linvoseltamab in people with relapsed or refractory multiple myeloma (cancer that has returned or stopped responding to treatment). The main goals are to check safety, find the best dose, and see if the combination shrinks tumors better than linvoseltamab alone. About 150 participants will take part, and the study is currently recruiting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- REGN17372 (an experimental bispecific antibody) combined with linvoseltamab (another bispecific antibody)
- What this could lead to
- If successful, this combination could offer a new treatment option for people with multiple myeloma that has stopped responding to other therapies.
- What could go wrong
- This is a very early (first-in-human) trial, so safety and effectiveness are not yet known. Side effects may occur, and the combination may not work better than existing treatments.
