Study Overview

TCR-T Cell Therapy on Advanced Pancreatic Cancer

The primary aim of this study is to evaluate the efficacy of KRAS mutant antigen specific TCR-T cells in the treatment of patients with advanced pancreatic cancer. The secondary aim is to evaluate the pharmacokinetic/pharmacodynamic characteristics of TCR-T cell therapy in patients with advanced pancreatic cancer and the survival of TCR-T cells. The investigators will evaluate the changes of tumor microenvironment after treatment of advanced pancreatic cancer with KRAS mutant antigen specific TCR-T cells; Evaluating the correlation between cytokines and the occurrence of CRS and neurotoxicity

1.This study is a prospective and single arm clinical study. In this trial, 18 patients with advanced pancreatic cancer with KRAS G12V or G12D mutations and matching HLA-A*11:01 subtypes are recruited for autologous Tumor-T Cell Receptor (TCR) -Mediated T Cells therapy(TCR-T) therapy.Within 3 - 5 days after pretreatment, subjects will receive a single TCR-T infusion with an infusion dose of about 1 × 10⁹～1 × 10¹⁰.Once every 12 hours within 24 hours after TCR-T cell infusion, recombinant human interleukin-2 will be injected intravenously for 14 days . After 3 months of treatment, the patient's condition was evaluated. If the subject did not occur tumor progression and did not occur adverse events (AEs) of level 3 or higher, a second TCR-T cell reinfusion can be performed (informed consent form needs to be signed again). The study will evaluate the safety of TCR-T treatment by observing adverse events after cell therapy; evaluate the effectiveness of TCR-T compared to the results or historical data of the subject's own previous standard treatment regimen;and collect blood before and after cell infusion, measure the number and activity of TCR-T cells, and evaluate the pharmacokinetic (PK) characteristics of TCR-T.

Secondary Outcome MeasuresMeasure DescriptionTime Frame
Peak plasma concentration (Cmax)Peak plasma concentration (Cmax) refers to the maximum concentration of TCR-T cells in peripheral blood after the TCR-T cells infusion.12months after the TCR-T cell infusion
Area under the plasma concentration versus time curve (AUC)Area under the plasma concentration versus time curve (AUC) is used to access the absorbed TCR-T cells dose into human blood circulation after TCR-T cells injection.12months after the TCR-T cell infusion
Peak time (Tmax)Peak time (Tmax) refers to the time when the blood concentration reaches the peak after TCR-T cells injection.12months after the TCR-T cell infusion
Cell number of TCR-T cells in peripheral bloodCell numbers of TCR-T cells after the injection of TCR-T cells12months after the TCR-T cell infusion
Peak value of cytokinesThe peak value of cytokines within 1 month after TCR-T cell infusion .1 month after TCR-T cell infusion
Adverse eventsThe type, incidence and severity of adverse events include abnormal laboratory examination results with clinical significance after treatment, abnormal physical examination and blood examination results, bone marrow examination results, etc. Clinical and laboratory adverse events will be classified according to the National Cancer Institute general terminology standard for adverse events (NCI CTCAE) version 5.0.12months after TCR-T infusion
