Detailed Description

This is an open-label, dose-escalation/dose extension study to assess the safety, tolerability, and efficacy of LCAR-AIO in the patient ≥ 18 years of age with relapsed or refractory B cell lymphoma. Subjects who meet the eligibility criteria will receive a single dose of LCAR-AIO injection. The study will include the following sequential phases: screening, pre-treatment (cell product preparation; lymphodepleting chemotherapy), treatment, and follow-up.
