Study Overview
Brief Summary
A Phase I Clinical Study to Evaluate the Safety, Tolerability, and Efficacy of the CD19/CD20 Dual-Target in vivo CAR-T Lentiviral product in the Treatment of Relapsed/Refractory B-cell Malignancies.
Detailed Description
This is an open-label, dose-escalation/dose extension study to assess the safety, tolerability, and efficacy of CD19/CD20 Dual-Target in vivo CAR-T Lentiviral product in the patient ≥ 18 years of age with relapsed or refractory B-cell Malignancies. Subjects who meet the eligibility criteria will receive a single dose of CD19/CD20 Dual-Target in vivo CAR-T Lentiviral product. The study will include the following sequential phases: screening, bridging therapy (if needed), treatment, and follow-up.

Outcomes
Primary Outcomes
Incidence, severity and type of TEAEs (Treatment-emergent Adverse Events)
Time Frame: Through study completion, an average of 2 years after LVIVO-TaVec100 infusion (Day 1)
An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
Pharmacokinetics in peripheral blood
Time Frame: Through study completion, an average of 2 years after LVIVO-TaVec100 infusion (Day 1)
CAR positive T cells and CAR transgene percentage of in peripheral blood after LVIVO-TaVec100 infusion.
Pharmacokinetics in bone marrow
Time Frame: Through study completion, an average of 2 years after LVIVO-TaVec100 infusion (Day 1)
