Could a custom vaccine stop cancer before it starts in lynch syndrome?

NCT ID NCT07163403

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage trial tests a personalized vaccine made from a person's own immune cells (dendritic cells) loaded with unique proteins found in Lynch syndrome-related cancers. The goal is to train the immune system to recognize and attack precancerous cells, potentially preventing cancer. Twenty Lynch syndrome carriers with no current cancer will receive six vaccine doses over 10 weeks, with researchers monitoring safety and immune response for a year.

What this could mean

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

Active substance
dendritic cells loaded with frameshift-derived neopeptides (a personalized vaccine made from the patient's own immune cells)
What this could lead to
If it works, this could lead to a vaccine that prevents cancer in people with Lynch syndrome, reducing their high lifetime cancer risk.
What could go wrong
This is a very early, small Phase 1 trial with only 20 people, so it may not show strong results or work for everyone. The main goal is safety, not yet effectiveness.
