Brief summary
The study is to assess the safety and efficacy of the immunotherapies using anti-MUC1 CAR T cells and /or PD-1 knockout engineered T cells in the treatment of patients with advanced esophageal cancer.
Detailed description
This is a combined phase 1 and 2 clinical study. The aim of the study is to assess the safety and efficacy of the immunotherapies using anti- MUC1 CAR T cells alone, anti- MUC1 CAR T combining PD-1 knockout engineered T cells, and PD-1 knockout engineered T cell only in the treatment of patients with advanced esophageal cancer. The treatment outcomes from each group will be compared.
Interventions
BIOLOGICALAnti-MUC1 CAR-T cells
Using the T cells from the patients' blood to produce anti-MUC1 CAR-T Cells and then the cells will be infused back to the patients.
BIOLOGICALPD-1 knockout Engineered T cells
Using the T cells from the blood of the patients to prepare PD-1 knockout T cells, then the cells will be infused back to the patients.
COMBINATION_PRODUCTCAR-T combined with PD-1 Knockout T cells
Using the T cells from the blood of the patients to prepare anti-MUC1 CAR-T Cells and PD-1 knockout T cells, then the cells will be infused back to the patients

Inclusion criteria
* Confirmed diagnosis of advanced esophageal cancer (phase IIIb-IV) according to NCCN clinical practice guidelines in Oncology:Esophageal and Esophagogastric Junction Cancers (2018.V1). * MUC1 is highly expressed in malignancy tissues by immuno-histochemical (IHC). * Eastern cooperative oncology group (ECOG) performance status of 0-1 or karnofsky performance status (KPS) score is higher than 60. * Patients have a life expectancy \> 12 weeks. * Adequate venous access for apheresis or venous sampling, and no other contraindications for leukapheresis. * Negative pregnancy test for females of child-bearing potentials. * Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements: White blood cell count (WBC) ≥ 2500c/ml, Platelets ≥ 50×10\^9/L, Hb ≥ 9.0g/dL, lymphocyte (LY) ≥ 0.7×10\^9/L, LY% ≥ 15%, Alb ≥ 2.8g/dL, serum lipase and amylase \< 1.5×upper limit of normal, serum creatinine ≤ 2.5mg/dL, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 5×upper limit of normal, serum total bilirubin ≤ 2.0mg/dL. These tests must be conducted within 7 days prior to registration. * Signed informed consent form.
Exclusion criteria
* Number of T cells is less than 10% or the amplification of the T cells via artificial antigen presenting cell (aAPC) stimulation is less than 5 times. * Patients with symptomatic central nervous system (CNS) involvement. * Pregnant or nursing women. * Known HIV, HBV and HCV infection. * Serious illness or medical condition which would not permit the patient to be managed according to the protocol, including active uncontrolled infection, major cardiovascular, coagulation disorders, respiratory or immune system, myocardial infarction, cardiac arrhythmias, obstructive/restrictive pulmonary disease, or psychiatric or emotional disorders. * History of severe immediate hypersensitivity to any of the agents including cyclophosphamide, fludarabine, or aldesleukin. * Concurrent use of systemic steroids. Recent or current use of inhaled steroids is not exclusionary. * Previously treatment with any gene therapy products. * The existence of unstable or active ulcers or gastrointestinal bleeding. Patients with portal vein vascular invasion or extrahepatic, are excluded from this study. * Patients with a history of organ transplantation or are waiting for organ transplantation.
