New antibody therapy shows promise for Hard-to-Treat myeloma
NCT ID NCT04557098
First seen Jun 25, 2026 · Last updated Jul 31, 2026 · Updated 4 times
Summary
This study tests a drug called teclistamab in people with multiple myeloma that has come back or stopped responding to treatment. The drug is a special antibody that helps the body's immune cells find and attack cancer cells. About 194 participants will receive the drug to see how well it shrinks tumors and how long the effect lasts.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- teclistamab (a bispecific antibody that helps immune cells attack myeloma cells)
- What this could lead to
- If successful, this could offer a new treatment option for people with multiple myeloma that has stopped responding to other therapies.
- What could go wrong
- This is an early-phase trial with a small number of participants. The drug may not work for everyone, and side effects like immune reactions are possible.
