Brief summary

Clinical Trial for the safety and efficacy of DeepTag-GPRC5D targeted CAR-T cells therapy for refractory/relapsed multiple myeloma

Detailed description

In this study, 60 patients with relapsed refractory multiple myeloma were proposed to undergo DeepTag-GPRC5D CAR-T cell therapy. Under the premise that its safety has been clarified in previous studies, further observation and evaluation of the effectiveness of DeepTag-GPRC5D CAR-T cell therapy for relapsed refractory multiple myeloma; At the same time, on the basis of expanding the sample size, more safety data on DeepTag-GPRC5D CAR-T cell treatment for relapsed refractory multiple myeloma were accumulated, including rare and delayed complications.
