Conditions
Brief summary
This is a single-center, non-randomized and dose-escalation study to evaluate the safety and efficacy of C-CAR066 in treatment of r/r DLBCL who received CD19 CAR-T therapy.

This study plans to enroll 10 patients to assess the safety and efficacy of C-CAR066. Subjects who meet the eligibility criteria will receive a single dose of C-CAR066 injection. The study will include the following sequential phases: Screening, Pre-Treatment (Cell Product Preparation, Lymphodepleting Chemotherapy), C-CAR066 infusion and Follow-up Visit.
