U87 CART in Treatment of Advanced Pancreatic Cancer
Study Details
Study Description
Brief Summary
This is a single center, open-label, phase 1 study to evaluate the safety and efficacy of U87 CART in treating advanced Pancreatic Cancer.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
|
Phase 1 |
Detailed Description
Following consent, patients must have tumor tissue evaluated by IHC assay. Patients meeting all eligibility criteria will undergo a leukapheresis procedure to collect autologous mononuclear cells for manufacture of investigational drug product (U87). Following manufacture of the drug product, subjects will receive preconditioning prior to U87 infusion. All subjects will be asked to continue to undergo long-term gene safety follow-up.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: U87 CAR-T cells The Patients are enrolled into 2 dose level cohorts in sequence |
Drug: U87 CAR-T
Subjects will be pretreated with cyclophosphamide 250~500 mg/m2( body surface area) for 3 days prior to Intratumoral injection of U87, followed by intraartery of U87 14 days later with intravenous IL-2. This study will explore two dose of dose 1 (DL-1): 1×106 (±20%) to dose 2 (DL-2): 1×107 (±20%),each group was enrolled in 3~6 patients.

Outcome Measures
Primary Outcome Measures
- Incidence of Adverse events after U87 CAR-T cells infusion [Safety and Tolerability] [28 days post administration of CAR-T-cells]
Therapy-related adverse events were recorded and assessed according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, Version 5.0) Dose-limiting toxicity after U87 CAR-T cells infusion.
Secondary Outcome Measures
- Disease control rate (DCR) of U87 CAR-T cells treatment in advanced pancreatic cancer. [Effectiveness] [2 years post CAR T cell infusion]
Disease control rate: including CR, PR and SD(Assessed based on RECIST 1.1 criteria)
- Objective response rate (ORR) of U87 CAR-T cells treatment in advanced pancreatic cancer. [Effectiveness] [2 years post CAR T cell infusion]
Objective response rate includes：CR、PR(Assessed based on RECIST1.1 criteria)
- Duration of Response (DOR) of U87 CAR-T cells treatment in advanced pancreatic cancer [Effectiveness] [2 years post CAR T cell infusion]
DOR will be assessed from the first assessment of CR/PR/SD to the first assessment of recurrence or progression of the disease or death from any cause
- Progress-free survival(PFS) of U87 CAR-T cells treatment in advanced pancreatic cancer [Effectiveness] [2 years post CAR T cell infusion]
PFS will be assessed from the first U87 CAR-T cells infusion to death from any cause or the first assessment of progression(Assessed based on RECIST1.1 ） criteria)
- Overall survival(OS) of U87 CAR-T cells treatment in advanced pancreatic cancer [Effectiveness] [2 years post CAR T cell infusion]
OS will be assessed from the first U87 CAR-T cells infusion to death from any cause (Assessed based on RECIST 1.1 criteria)
- Pharmacokinetics of U87 CAR-T cells [2 years post CAR T cell infusion]
Peak value of eripheral blood (Cmax)
- Pharmacokinetics of U87 CAR-T cells [2 years post CAR T cell infusion]
Area under the eripheral blood concentration versus time curve (AUC)
- Pharmacokinetics of U87 CAR-T cells [2 years post CAR T cell infusion]
Time of peak value
- Pharmacodynamics of U87 CAR-T cells [2 years post CAR T cell infusion]
Concentration levels of CAR-T-related serum cytokines such as IL-6, IFN γ, IL-2, TNFα, ferritin and CRP at each time point
