NCT ID NCT04634552
First seen Jun 27, 2026 · Last updated Aug 28, 2026 · Updated 3 times
Summary
This study tests a new drug called talquetamab in people with multiple myeloma that has come back or stopped responding to treatment. Talquetamab is a bispecific antibody designed to help the immune system attack cancer cells. The trial aims to find the best dose and see how well it shrinks tumors. About 510 participants will take part.
