Обзор

A phase I, open-label clinical study to evaluate the safety, tolerability, and efficacy of LUCAR-E9D,LUCAR-E9K, a dual-targeted cell preparation targeting CD19/CD20, in patients with relapsed/refractory B-cell non-Hodgkin lymphoma.

Подробное описание

This is an open-label, dose-escalation/dose extension study to assess the safety, tolerability, and efficacy of LUCAR-E9D,LUCAR-E9K in the patient ≥ 18 years of age with relapsed or refractory B-cell non-Hodgkin lymphoma. Subjects who meet the eligibility criteria will receive a single dose of LUCAR-E9D,LUCAR-E9K injection. The study will include the following sequential phases: screening, pre-treatment (lymphodepleting chemotherapy), treatment, and follow-up.

Вмешательства

• Биопрепарат LUCAR-E9D or LUCAR-E9K cells product
  Prior to infusion of the LUCAR-E9D or LUCAR-E9K cells product subjects will receive a conditioning premedication regimen consisting of cyclophosphamide and fludarabine
