Custom-Made vaccine targets pancreatic cancer in early human test

NCT ID NCT05111353

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 1 trial tested a personalized vaccine made from each patient's unique cancer mutations (neoantigens) combined with an immune booster (poly-ICLC) in 33 people with pancreatic cancer. The vaccine was given after standard chemotherapy, either before or after surgery. The main goal was to check safety and see if the vaccine could trigger an immune response against the cancer.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

personalized neoantigen synthetic long peptide vaccine plus poly-ICLC (Hiltonol)

What this could lead to

If successful, this could pave the way for a new personalized vaccine approach to help the immune system fight pancreatic cancer after standard chemotherapy.

What could go wrong

This is a very early phase 1 trial with only 33 participants, so safety and immune response are the main goals—not yet proof of effectiveness. The vaccine is custom-made for each patient, which limits scalability and may not work for everyone.
