About

The goal of this clinical trial is to learn about Phase I+Phase II Clinical Study of PRaG Therapy in Combination With Chemotherapy (AG Regimen) for Neoadjuvant Treatment of Locally Advanced Pancreatic Ductal Adenocarcinoma (PDAC) (NeoPRAG Study).The main question it aims to answer is to investigate the safety and efficacy of the PRaG treatment modality combined with chemotherapy neoadjuvant therapy for locally advanced pancreatic cancer.

Inclusion criteria

Age ≥ 18 ≤ 75 years；no gender limitations

Locally advanced pancreatic cancer, borderline resectable or unresectable, without metastases.
Life expectancy >= 3 months.
ECOG score 0-1.
Have at least 1 measurable lesion according to RECIST 1.1 criteria.
No prior treatment with abdominal radiotherapy, chemotherapy and PD-1/PD-L1 antibody.
Adequate organs functions as defined by the following laboratory values (completed within 14 days prior to registration): (1) haemoglobin >= 90 g/L (no blood transfusion within 14 days)； (2) neutrophil count > 1.5x10^9/L； (3) platelet count >= 100x10^9/L； (4) total bilirubin <= 1.5xULN (upper limit of normal)； (5) blood glutamic transferase (ALT) or blood glutamic transferase (AST) <= 2.5xULN (6) endogenous creatinine clearance >= 60 ml/min (Cockcroft's AST).
