About

Evaluation of the safety and efficacy of BCMA nanobody CAR-T cells in relapsed/refractory myeloma

Full description

There are no effective regimens for relapsed/refractory myeloma. BCMA express extensively in mature B cells and plasma cells. Myeloma cells express BCMA universally. BCMA signal pathway can induce plasma cell proliferation and survival, down-regulation of BCMA could control the progression of myeloma. The BCMA CAR used in this study consists of BCMA nanobody, CD8 hinge, transmembrane region and 4-1bb co-stimulation domain.

Enrollment: 15 estimated patients

Sex: All

Ages: 18 to 70 years old
