2. At least one measurable objective lesion (both primary and metastatic) was identified based on the RECIST 1.1 criteria;

3. Eastern Cooperative Oncology Group (ECOG) performance status 0-1;

4. The expected survival after surgery ≥ 3 months

5. The subjects have good compliance, can be treated and followed up, and voluntarily comply with the relevant provisions of this study

6. No contraindications for camrelizumab, gemcitabine and nab-paclitaxel. 3. Age and reproductive status

1. Male and female patients at the age of 18-75

2. Subjects of child-bearing age must agree to take effective contraceptive measures during the study period; Serum or urine pregnancy tests must be negative for women of childbearing age 24 hours before the start of therapy;

3. Women must not lactate.

Exclusion Criteria:

• 1. The target disease has cerebral metastasis; 2. Previously treated by anti-PD-1 or anti-PD-L1 drugs; 3. Received any investigational drug within 4 weeks before the first use of the research drug; 4. Enrolled in another clinical study, unless it is an observational (non-interventional) clinical study or an interventional follow-up clinical study; 5. medical history and complications

1. patients had uncontrolled serious medical condition that the investigator considered may affect the subject's to receive treatment under the study program. For example, patients with severe medical diseases, including severe heart disease, cerebrovascular disease, uncontrolled diabetes, uncontrolled hypertension, uncontrolled infection, active peptic ulcer, etc.

2. patients who are suffering active, known or suspected autoimmune diseases (including but limited to uveitis, enteritis, hepatitis, pituitary inflammation, nephritis, vasculitis, hyperthyroidism, hypothyroidism and asthma requiring bronchodilator therapy, etc.). Subjects with hypothyroidism who only need hormone replacement therapy and skin diseases that do not require systemic treatment (such as vitiligo, psoriasis, or hair loss) can be enrolled;

3. Patients who are suffering from active tuberculosis infection: Patients with active pulmonary tuberculosis infection within 1 year before medication should be excluded even if they have been treated; patients with a history of active tuberculosis infection more than 1 year ago should also be excluded unless it is proven that they have received standard anti-TB treatment before;

4. Patients who have previous interstitial lung disease or (non-infectious) pneumonia and requires oral or intravenous steroid therapy;

5. Patients who need to receive long-term systemic hormones (dose equivalent to >10mg prednisone/day) or any other form of immunosuppressive therapy. Subjects using inhaled or topical corticosteroids can be enrolled;

6. Patients who have uncontrolled heart disease, such as:

1. New York Heart Association (NYHA) level 2 heart failure;

2. Unstable angina;

3. Myocardial infarction occurred within 1 year

4. Supraventricular or ventricular arrhythmias that have clinical significance and require treatment or intervention

7. Dementia, changing of mental state or any mental illness which could hinder understanding or informed consent or fill out questionnaires;

8. History of allergy or hypersensitivity to any therapeutic ingredient;

9. Combined with other malignant tumors excepted pancreatic cancer within the first 5 years of randomization, excepted well-treated basal cell or squamous cell carcinoma of the skin, localized prostate cancer after radical resection, and ductal carcinoma in situ of the breast after radical resection;

10. Previously received systemic therapy for advanced/metastatic pancreatic cancer;

11. Subjects who had previously been pathologically diagnosed with squamous cell carcinoma (no organ limitation) and received neoadjuvant/adjuvant therapy with taxa regimen.

12. Patients who had Grade 2 or above Peripheral neuropathy according to CTCAE Ver. 5.0.

6. Abnormal results of physical examination and laboratory examination

1. Absolute neutrophil count (ANC) ≥ 1.5×109/L; Platelets (PLT) ≥ 80×109/L; Hemoglobin (Hb) ≥ 90g/L

2. Aspartate aminotransferase (AST, or serum glutamic oxaloacetic transaminase, SGOT) and alanine aminotransferase (ALT, or serum glutamic pyruvate transaminase, SGPT) > 2.5 × ULN (institutional upper limit of normal), > 5 ×ULN (hepatic metastases occasion); Total bilirubin (TBIL)>1.5 × ULN;

3. Creatinine (CRE)> 1.5 × ULN

4. Prothrombin time (PT) and international normalized ratio (INR) > 1.5 × ULN. Or activated partial thromboplastin time (aPTT) > 1.5 × ULN. Unless the subject had received anticoagulant treatment

5. Subjects had hepatitis b surface antigen (HBsAg)-positive and HBV-DNA titer in peripheral blood greater than or equal to 1000 copy number /L; If HBsAg is positive and the HBV-DNA of peripheral blood ≥ 1000 copy number/L, the subjects will be eligible for inclusion if the investigator considers that chronic hepatitis b is stable and does not increase the risk of subjects.

4. Human immunodeficiency virus (HIV)- or hepatitis C virus (HCV) positive patients;

5. Patients who suffer from active infection requiring systemic treatment; 6. Patients need other concomitant anti-tumor drugs; 7. Participation in any trial drug treatment or another interventional clinical trial 30 days before screening period.

8. Other conditions that the investigators considered are not suitable for the enrollment.
