Detecting the Chimeric Antigen Receptor T-cells Idecabtagene Vicleucel and Ciltacabtagene Autoleucel in Patients with Multiple Myeloma

Research with blood and cells (generally called specimens) can help researchers understand how the human body works. Research can also answer other questions by using specimens. Researchers may develop new tests to find diseases, or new ways to treat diseases. In the future, research may help to develop new products, such as drugs. You are being asked for permission to use your biospecimens and medical records for this study. Using your biospecimens, researchers may be able to detect CAR-T cells in your body after you receive the CAR-T treatment. The purpose of this study is to validate the detection method of CAR-T cells in the blood to advance CAR-T therapy development.
