Overview
Brief Summary
An open label, single arm Phase I study to evaluate the safety, tolerability, and pharmacokinetics of LUCAR-20S CAR-T cells in relapsed or refractory CD20+ diffuse large B-cell, follicular, mantle cell and small lymphocytic lymphoma.
Detailed Description
This study is an open, dose escalation/dose regimen finding study to assess the safety and pharmacokinetics of donor-derived CD20-directed CAR-T cells administered with lymphodepletion, and to obtain the preliminary efficacy results in subjects who have been diagnosed with relapsed or refractory CD20 positive diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma or small lymphocytic lymphoma. The allo-CAR-T cells will be infused in single-dose.

- •Prior antitumor therapy with insufficient washout period
- •Targeted therapy, epigenetic therapy, experimental drug therapy or experimental invasive treatment with medical apparatus and instruments 14 days or five half-lives, whichever is shorter before lymphodepletion
- •Use of monoclonal antibodies 21 days prior to lymphodepletion
