New combo therapy targets Hard-to-Treat myeloma
NCT ID NCT05259839
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This early-stage study tests a new drug called etentamig combined with standard treatments for people with multiple myeloma that has come back or stopped responding to therapy. About 320 adults will take part to find the safest dose and check for side effects. The goal is to control the disease, not cure it.
