ClinConnect Summary

This clinical trial is exploring a new personalized treatment for patients with pancreatic cancer that can be surgically removed (resectable). The study will test a special therapy using messenger RNA (mRNA) designed to help the immune system recognize and fight cancer cells, combined with a standard chemotherapy and an antibody treatment. The goal is to see if this new treatment is safe and effective for patients who have just undergone surgery for their cancer.

To join the trial, participants must be at least 18 years old, have a confirmed diagnosis of pancreatic cancer, and have had surgery to remove the tumor. They should also be in good health overall, with normal function of their major organs. Participants will be closely monitored throughout the study, and they will need to agree to use contraception if they are able to have children. This trial is not yet open for recruitment, but it aims to provide valuable insights into a promising new treatment option for pancreatic cancer patients.

  • * Normal function of major organs (heart, liver, kidneys):
  • Contraception agreement: Same as pre-screening criteria;
  • Ability to comply with the study protocol and follow-up procedures.
  • Exclusion Criteria:
  • Subjects meeting any of the following criteria will be excluded from the study:
  • Serum CA 19-9 level \>180 U/mL within 21 days prior to initiating standard postoperative adjuvant therapy;
  • History of bone marrow transplantation, allogeneic organ transplantation, or allogeneic hematopoietic stem cell transplantation;

  • 2. Active autoimmune disease or immunodeficiency (e.g., rheumatoid arthritis, systemic lupus erythematosus);
  • 3. History of primary immunodeficiency;
  • 4. Exceptions: Type 1 diabetes, autoimmune hypothyroidism managed with hormone replacement, vitiligo, or psoriasis not requiring systemic therapy;

  • 2. Syphilis (TP antibody-positive with RPR/TRUST confirmation);
  • 3. Active hepatitis C (HCV RNA-positive);
  • 4. Active hepatitis B (HBsAg-positive and HBV DNA ≥2000 IU/mL);
  • * Acute viral infections:
  • 1. Herpesvirus infection (unless resolved with crusting \>4 weeks prior);

  • * Uncontrolled comorbidities:
  • 1. Symptomatic congestive heart failure (NYHA Class III/IV);
  • 2. Unstable angina or arrhythmia requiring treatment;
