Study Details
Study Description
Brief Summary
This is a single-center, open-label and pragmatic clinical trial to evaluate the primary efficacy and safety of anti-CD19 chimeric antigen receptor (CAR)-modified T cells (CART-CD19) with concurrent BTK inhibitor in patients with relapsed or refractory B cell lymphoma

Detailed Description
Anti-CD19 chimeric antigen receptor (CAR) T-cell has shown dramatical efficacy in B cell malignancies. And Bruton tyrosine kinase (BTK) inhibitor agents have been validated as an effective drug to treat B cell malignancies. Combined therapies comprising ibrutinib (a BTK inhibitor) and anti-CD19 CAR-T cells in patients with CLL after ibrutinib failure are considered feasible and safe.
Ibrutinib is the first-generation BTK inhibitror and Zanubrutinib is the second-generation BTK inhibitor. Orelabrutinib is a newly developed BTK inhibitor with high selectivity and have received its approval in China. Autologous cells derived T cells are purified and transduced with a retroviral vector encoding the humanized CD19 scFv.
To evaluate whether the addition of BTK inhibitor (Ibrutinib, Zanubrutinib and Orelabrutinib) in anti-CD19 CAR-T cells therapy would further improve efficacy and safety, we intend to conduct this pragmatic clinical trial.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Effective of CAR-T-CD19 cells with concurrent BTK inhibitor After enrollment, all subjects will receive oral BTK inhibitor immediately and BTK inhibitor treatment will continue for up to 90 days (or longer for who are benefiting from BTK inhibitor) after CAR-T-CD19 infusion. Eligible patients will undergo leukapheresis to obtain peripheral blood mononuclear cells (PBMCs) for CAR T-cell production. Upon successful generation CAR-T-CD19 product, participants will receive lymphodepletion with low dose fludarabine and cyclophosphamide on day -5 to -3, followed by one infusion of CAR-T-CD19 cells (2*10^6 to 4*10^6 cells/kg) on day 0. |
Drug: BTK inhibitor+ Fludarabine + Cyclophosphamide + CAR-T-CD19 Cells
BTK inhibitor from enrollment to 90 days after CAR-T-CD19 infusion. Low dose fludarabine and cyclophosphamide on day -5 to -3. CAR-T-CD19 cells (2*10^6 to 4*10^6 cells/kg) on day0.
|
| Active Comparator: Effective of CAR-T-CD19 cells monotherapy Eligible patients will undergo leukapheresis to obtain peripheral blood mononuclear cells (PBMCs) for CAR T-cell production. Upon successful generation CAR-T-CD19 product, participants will receive lymphodepletion with low dose fludarabine and cyclophosphamide on day -5 to -3, followed by one infusion of CAR-T-CD19 cells (2*10^6 to 4*10^6 cells/kg) on day 0. |
Drug: Fludarabine + Cyclophosphamide + CAR-T-CD19 Cells
Low dose fludarabine and cyclophosphamide on day -5 to -3. CAR-T-CD19 cells (2*10^6 to 4*10^6 cells/kg) on day0.

Outcome Measures
Primary Outcome Measures
- Progress-free survival (PFS) of administering CAR- T-CD19 cells or CAR-T-CD19 cells with oral BTK inhibitor in Relapsed/Refractory CD19+ B-cell lymphoma. [within 2 years after infusion]
PFS will be assessed from CAR-T cell infusion to death or last follow-up
Secondary Outcome Measures
- Overall response rate (ORR) of administering CAR-T-CD19 cells or CAR-T-CD19 cells with oral BTK inhibitor in Relapsed/Refractory B cell lymphoma. [within 2 years after infusion]
ORR will be assessed from CAR-T cell infusion to death or last follow-up (censored).
- Duration of Response (DOR) of administering CAR- T-CD19 cells or CAR-T-CD19 cells with oral BTK inhibitor in Relapsed/Refractory CD19+ B-cell lymphoma. [within 2 years after infusion]
DOR will be assessed from CAR-T cell infusion to death or last follow-up (censored).
- Overall survival (OS) of administering CAR- T-CD19 cells or CAR-T-CD19 cells with oral BTK inhibitor in Relapsed/Refractory CD19+ B-cell lymphoma. [within 2 years after infusion]
OS will be assessed from CAR-T cell infusion to death or last follow-up (censored).
- Event-free survival (EFS) of administering CAR- T-CD19 cells or CAR-T-CD19 cells with oral BTK inhibitor in Relapsed/Refractory CD19+ B-cell lymphoma. [within 2 years after infusion]
EFS will be assessed from CAR-T cell infusion to death or last follow-up (censored).
- Incidence of Treatment-related Adverse Events [within 2 years after infusion]
Therapy-related adverse events (AE), including severe adverse events (SAE) and laboratory outliers with clinical significance, will be recorded and assessed according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, Version 5.0).
- Complete response rate (CR) of administering CAR-T-CD19 cells or CAR-T-CD19 cells with oral BTK inhibitor in Relapsed/Refractory B cell lymphoma. [within 2 years after infusion]
CR will be assessed from CAR-T cell infusion to death or last follow-up (censored).
- Partial response rate (PR) of administering CAR-T-CD19 cells or CAR-T-CD19 cells with oral BTK inhibitor in Relapsed/Refractory B cell lymphoma. [within 2 years after infusion]
PR will be assessed from CAR-T cell infusion to death or last follow-up.
Other Outcome Measures
- In vivo expansion and survival of CAR-T-CD19 cells [within 2 years after infusion]
Quantity of CAR-T-CD19 CAR copies in bone marrow, peripheral blood and cerebrospinal fluid will be determined by using quantitative polymerase chain reaction.
