CD30 CAR-T in the Treatment of CD30 Positive Lymphoma

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

To evaluate the safety and maximum tolerated dose 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.
