This study is to investigate the safety and efficacy of gene-edited tumor infiltrating lymphocyte (GC203 TIL) therapy in patients with pancreatic ductal adenocarcinoma. Gene-edited TILs are expanded from tumor resections or biopsies and infused i.v. into the patient after NMA lymphodepletion treatment with hydroxychloroquine(600mg,single-dose) and cyclophosphamide.
have done the tumor resection for gene-edited GC203 TIL production and successfully produced；
Age: 18 years to 70 years;
Histologically diagnosed as pancreatic ductal adenocarcinoma;
Expected life-span more than 3 months;
with other malignant tumors,except for the malignancies that have been cured, have been inactive for ≥5 years prior to study inclusion and have a very low risk of recurrence; Non-melanoma skin cancer or malignant lentigo with adequate treatment and no evidence of disease recurrence; Carcinoma in situ with adequate treatment and no evidence of disease recurrence;
Need glucocorticoid treatment, and daily dose of Prednisone greater than 10mg(or equivalent doses of hormones) or outoimmune diseases requiring immunomodulatory treatment;
Breathe indoor air in a quiet state, and the oxygen saturation of finger pulse is < 95%;
Human immunodeficiency virus (HIV) infection or anti-HIV antibody positive, active HBV or HCV infection (HBsAg positive and/or anti-HCV positive), syphilis infection or Treponema pallidum antibody positive;
Single group
GC203 TIL
Biological/Vaccinethe candidates will be assigned to GC203 TIL(gene-edited TIL) group
Adverse Events
To characterize the safety profile of GC203 TIL in patients with pancreatic ductal adenocarcinoma who were failed to standard treatment as assessed by incidence of adverse events.
Objective Response Rate (ORR)
Proportion of patients with response per Response Evaluation Criteria in Solid Tumors (RECIST v1.1)
Disease Control Rate (DCR）
Percentage of patients that meet CR, PR and SD criteria set in this study according to RECIST 1.1
Duration of Response (DOR)
The time length between the first confirmed objective response per RECIST 1.1 to the treatment and the subsequent disease progression per RECIST 1.1
Progression-Free Survival (PFS)
The time length between TIL infusion and confirmed subsequent disease progression according to RECIST 1.1
