Study of Neoantigen mRNA Vaccines in Patients With Resectable Pancreatic Cancer

Prior treatment

• Prior neoadjuvant treatment, radiation therapy, anti-PD-1 antibody or any other immune therapy for pancreatic ductal adenocarcinoma.
• Known infection with hepatitis B or C, or history of human immunodeficiency virus (HIV) infection or subjects receiving immunosuppressive or myelosuppressive medications that would, in the opinion of the investigator, increase the risk of serious neutropenic complications.

Other illness

• Known hypersensitivity or allergy to the active substance or to any of the excipients of SJ-neo006, Camrelizumab, Gemcitabine, Abraxane.
• Actie, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy, defined as ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment.
• New York Heart Association (NYHA) Class III-IV heart failure, uncontrolled hypertension, clinically significant cardiac dysthythmia, or electrocardiogram abnormality, cerebrovascular accident, transient ischemic attack, or seizure disorder.
• History or autoimmune disease, including but not limited to systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease.

Other

• Pregnancy, breastfeeding, or intending to become pregnant during the study or within 90 days after the last dose of study treatment.
• Any situation judged by the investigators that may increase the risk of the subjects or interfere with the clinical trial outcome.

• Subjects voluntarily participate in this clinical study and sign the Informed Consent Form (ICF).
• Subjects must be \>/= 18 years of age at time of informed consent.
• Subjective with radiographically resectable primary pancreatic tumors with radiographic features consistent with adenocarcinoma will be evaluated for surgical resection.
• Subjects with histologically confirmed resected ductal pancreatic adenocarcinoma with macroscopic complete resection (R0 and R1) will be selected for neoantigen vaccine creation.
• Performance status of 0 or 1 on Eastern Cooperative Oncology Group (ECOG).
• Subjects must not have had prior chemotherapy, radiation therapy, or immunotherapy for Pancreatic ductal adenocarcinoma（PDAC）.
• Subjects with estimated survival \> 12 weeks.
