PD-1 Knockout Engineered T Cells for Metastatic Non-small Cell Lung Cancer
Purpose| Condition | Intervention | Phase |
|---|---|---|
| Metastatic Non-small Cell Lung Cancer | Drug: Cyclophosphamide Other: PD-1 Knockout T Cells Drug: Interleukin-2 | Phase 1 |
| Study Type: | Interventional |
| Study Design: | Allocation: Non-Randomized Endpoint Classification: Safety Study Intervention Model: Parallel Assignment Masking: Open Label Primary Purpose: Treatment |
| Official Title: | A Dose-escalation Phase I Trial of PD-1 Knockout Engineered T Cells for the Treatment of Metastatic Non-small Cell Lung Cancer |
Number of participants with Adverse Events and/or Dose Limiting Toxicities as a Measure of Safety and tolerability of dose of PD-1 Knockout T cells using Common Terminology Criteria for Adverse Events (CTCAE v4.0) in patients [ Time Frame: Dose Escalation - Approximately 6 months ] [ Designated as safety issue: Yes ]
Response Rate [ Time Frame: 90 days ] [ Designated as safety issue: No ]
Response will be evaluated according to RECIST v1.1Progression free survival - PFS [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to average 10 months ] [ Designated as safety issue: No ]
Overall Survival - OS [ Time Frame: The time from randomization to death from any cause, assessed up to 2 years ] [ Designated as safety issue: No ]
Peripheral blood circulating tumor DNA [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
Peripheral circuiting tumor DNA is collected at baseline and 6 weeks after last treatmentTemporal Interleukin-2 change in the peripheral blood [ Time Frame: Baseline and 1 month and 3 months ] [ Designated as safety issue: No ]
Temporal Interferon-γ change in the peripheral blood [ Time Frame: Baseline and 1 month and 3 months ] [ Designated as safety issue: No ]
Temporal tumour necrosis factor-α change in the peripheral blood [ Time Frame: Baseline and 1 month and 3 months ] [ Designated as safety issue: No ]
Temporal Interleukin-6 change in the peripheral blood [ Time Frame: Baseline and 1 month and 3 months ] [ Designated as safety issue: No ]

| Arms | Assigned Interventions |
|---|---|
| Experimental: A - Two cycles Peripheral blood lymphocytes will be collected and Programmed cell death protein 1(PDCD1) gene will be knocked out by CRISPR Cas9 in the laboratory (PD-1 Knockout T cells). The lymphocytes will be selected and expanded ex vivo and infused back into patients. Cyclophosphamide at 20mg/kg single dose will be administered 3 days i.v. before cell infusion. A total of 2 x 10^7/kg PD-1 Knockout T cells will be infused in one cycle. Each cycle is divided into three administrations, with 20% infused in the first administration, 30% in the second, and the remaining 50% in the third. Interleukin-2 (IL-2) will be given in the following 5 days, 720000 international unit（IU）/Kg/day (if tolerant). Patients will receive a total of two cycles of treatment. | Drug: Cyclophosphamide To deplete Tregs before collecting peripheral blood Other Name: Cytoxan Other: PD-1 Knockout T CellsAutologous lymphocytes are collected and PDCD1 gene is knocked out in the laboratory. Cells are selected and expanded ex vivo. Cells are infused back to the patients for treatment Drug: Interleukin-2Given in the following 5 days at 720,000 international unit（IU）/Kg/day Other Name: IL-2 |
