CD30 CAR-T in the Treatment of CD30 Positive Relapsed/Refractory Lymphoma

Clinical Study on the Safety and Efficacy of Chimeric Antigen Receptor Gene Modified T Cells Targeting CD30 in the Treatment of CD30 Positive Relapsed/Refractory Lymphoma

The is a prospective, open-label, dose-climbing clinical study assessing the efficacy and safety of CD30 CAR-T in the treatment of r/r CD30+ lymphoma. Plan to recruit 15 subjects with r/r CD30+ lymphoma。

The goal of this clinical trial is to explore the effect of CD30 CAR-T on CD30 positive relapsed/refractory lymphoma. The main questions it aims to answer are:

To evaluate the safety of autologous CD30 CAR-T therapy in CD30-positive relapsed/refractory lymphoma; To evaluate the efficacy of autologous CD30 CAR-T therapy for CD30-positive relapsed/refractory lymphoma; To evaluate the metabolism of CD30 CAR-T cells in vivo; Preliminary evaluation of the correlation between CAR T cell dose and clinical efficacy.
