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.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
