Study Details

Study Description

Brief Summary

It is a single-center, open-labeled, single-arm, non-randomized, investigator-initiated trial aiming to evaluate the efficacy and safety of anti-CD19 CAR-T manufactured by OlyCAR platform (OlyCAR-019) for CD19+ refractory/relapsed B-Cell malignancies.

Condition or Disease	Intervention/Treatment	Phase
B-Cell Leukemia B-Cell Lymphoma B-cell Tumors	Biological: Anti-CD19 Autologous CAR-T Cell Infusion	Phase 1/Phase 2

Detailed Description

OlyCAR is a novel CAR-T manufacturing system which allows to generate clinical-use CAR-T cells in short time. This study is going to evaluate the feasibility of CAR-T manufactured by OlyCAR platform in the treatment of B-Cell malignancies. The OlyCAR-019 cells will be infused by vein. Subjects will be followed for safety and efficacy up to 12 weeks. For those with a durable remission 12 weeks after infusion, the follow-up will last for at least 12 months for disease control.

Outcome Measures

Primary Outcome Measures

Incidence of adverse events(AE) after infusion [Up to 12 months after infusion]
The frequency, severity, and laboratory findings of all adverse events/serious adverse events are included.
MTD [Up to 28 days after infusion]
MTD will be determined based on DLTs observed during the first 28 days of study treatment.

Secondary Outcome Measures

Overall Response Rate (ORR) [Up to 3 months after infusion]
Overall Response Rate (ORR) is defined as the proportion of subjects achieving complete remission(CR) and partial response(PR).
Progression-free survival(PFS) [Up to 3 months after infusion]
Progression-free survival(PFS) refers to the time from cell infusion to the first assessment of tumor progression or death from any cause.
