Pancreatic cancer is a common malignant tumor of digestive tract, and its morbidity and mortality are increasing worldwide. Few clinical data have been published on immunotherapy for pancreatic cancer. This trial is a prospective, single-arm, single-center clinical study to investigate the efficacy and safety of sintilimab in combination with gemcitabine and albumin-paclitaxel conversion therapy with unresectable locally advanced pancreatic cancer.


This is a prospective, single-arm, single-center clinical study to investigate the efficacy and safety of sintilimab in combination with gemcitabine and albumin-paclitaxel conversion therapy with unresectable locally advanced pancreatic cancer.

The primary endpoint is R0-surgery resection rate. Objective response rate, overall survival , progression-free survival, event free survival, adverse events will be recorded and analyzed, to assess the efficacy and safety of the combination treatment with sintilimab and paclitaxel (albumin-bound) and gemcitabine with metastatic pancreatic cancer. The study will also explore biomarkers that can predict efficacy, and blood and tumor samples will be collected/collected at baseline and during the trial for patients who sign informed consent, including possible tumor biopsies at baseline.

Inclusion Criteria

Signed the Informed Consent Form; 2. Age ≥18 and ≤ 75, no gender limitation; 3. Histopathological diagnosis of pancreatic cancer; 4. Patients with unresectable initial local progression and no prior antitumor therapy (radiotherapy, chemotherapy, targeted or immunotherapy, etc.); 5. According to the efficacy evaluation criteria for solid tumors (RECIST version 1.1), at least one lesion can be measured on imaging; 6. ECOG score 0-1; 7. Expected survival time >3 months; 8. Adequate organ function, patient shall meet the following laboratory criteria
Absolute value of neutrophils (ANC) ≥1.5x109/L without the use of granulocyte colony-stimulating factor in the last 14 days
Platelets ≥75×109/L in the last 14 days without blood transfusion
Hemoglobin >9g/dL in the absence of blood transfusion or erythropoietin in the last 14 days
total bilirubin ≤2× upper limit of normal value (ULN) or ≤50umol/L
Aspartate aminotransferase (AST), alanine aminotransferase (ALT) ≤5×ULN
Serum creatinine ≤1.5×ULN and creatinine clearance rate (calculated by Cockcroft-Gault formula) ≥60 mL /min
Good coagulation function, defined as international standardized ratio (INR) or prothrombin time (PT) ≤1.5 ULN
Normal thyroid function, defined as thyroid stimulating hormone (TSH) within the normal range. If the baseline TSH is outside the normal range, patients with total T3 (or FT3) and FT4 within the normal range may be enrolled; 9. For female patients of reproductive age, a negative urine or serum pregnancy test should be performed within 3 days prior to receiving the first study drug administration (day 1 of cycle 1). If a urine pregnancy test result cannot be confirmed as negative, a blood pregnancy test is requested. Women of childbearing age were defined as at least 1 year after menopause or having undergone surgical sterilization or hysterectomy; 10. If there is a risk of conception, all patients (both men and women) will be required to use a contraceptive with an annual failure rate of less than 1% for the entire treatment period up to 120 days after the last study drug (or 180 days after the last chemotherapeutic drug)

Exclusion Criteria

\. Malignant diseases other than pancreatic cancer were diagnosed within 5 years prior to first administration (excluding radical basal cell carcinoma of the skin, squamous carcinoma of the skin, and/or radical resected carcinoma in situ); 2. Patients who are currently participating in an interventional clinical study or have been treated with another study drug or study device within 4 weeks prior to initial administration; 3. Prior treatment with anti-PD-1, anti-PD-L1, or anti-PD-L2 drugs or drugs that target another stimulating or co-inhibiting T-cell receptor (e.g., CTLA-4, OX-40, CD137); 4. Received systemic therapy with anti-tumor indications of Proprietary Chinese medicines or immunomodulatory drugs (including interferon and interleukin, except local use for ascites control) within 2 weeks before the first administration; 5. An active autoimmune disease requiring systemic therapy (e.g., palliative drugs, glucocorticoids or immunosuppressants) has occurred within 2 years prior to first dosing. Alternative therapies (e.g. thyroxine, insulin, or physiologic glucocorticoids for adrenal or pituitary dysfunction) are not considered systemic; 6. Patients who were receiving systemic glucocorticoid therapy (excluding nasal spray, inhalation, or other topical glucocorticoid) or any other form of immunosuppressive therapy within 7 days prior to initial dosing; Note: Physiological doses of glucocorticoids (≤10 mg/ day of prednisone or equivalent) are permitted; 7. Allogeneic organ transplantation (except corneal transplantation) or allogeneic hematopoietic stem cell transplantation is known; 8. Those who are known to be allergic to active ingredients or excipients of sintilimab, gemcitabine and albumin-paclitaxel; 9. Has not fully recovered from toxicity and/or complications associated with any intervention prior to initiation of treatment (i.e., ≤ grade 1 or baseline, excluding fatigue or hair loss); 10. Known history of human immunodeficiency virus (HIV) infection (i.e. HIV 1/2 antibody positive); 11. Uncontrolled active hepatitis B (defined as HBsAg positive with hbV-DNA copy number greater than the upper limit of the normal value in the laboratory department of the research center)
Note: Hepatitis B subjects who meet the following criteria can also be
HBV viral load <1000 copies/mL (200 IU/ml) before initial administration, subjects should receive anti-HBV therapy throughout study drug therapy to avoid virus reactivation
For subjects resistant to HBc (+), HBsAg (-), anti-HBS (-), and HBV viral load (-), prophylactic anti-HBV therapy is not required, but close monitoring of virus reactivation is required 12. Active HCV-infected subjects (HCV antibody positive and HCV-RNA level above the detection limit); 13. Received live vaccine within 30 days prior to initial administration (cycle 1, day 1); Note: Acceptance of injectable inactivated virus vaccine against seasonal influenza is permitted within 30 days prior to first administration; Intranasally administered live attenuated flu vaccines are not allowed
Pregnant or lactating women; 15. Presence of any serious or uncontrollable systemic illness, such as
Serious and uncontrollable abnormalities in the rhythm, conduction or morphology of resting electrocardiogram, such as complete left bundle branch block, heart block above degree ⅱ, ventricular arrhythmia or atrial fibrillation
Unstable angina pectoris, congestive heart failure, NYHA grade ≥ 2 chronic heart failure
