Could a yeast vaccine stop Cancer's return?
NCT ID NCT05952934
First seen Jun 25, 2026 · Last updated Sep 16, 2026 · Updated 3 times
Summary
This study tests a vaccine made from candida (a type of yeast) to see if it can reduce the risk of head and neck cancer coming back. About 100 adults who have finished cancer treatment and are currently cancer-free will receive either the vaccine or a placebo over two years. The goal is to compare recurrence rates between the two groups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Candin (candida therapeutic vaccine)
- What this could lead to
- If it works, this could offer a new way to lower the chance of head and neck cancer coming back after standard treatment.
- What could go wrong
- This is an early phase II trial with only 100 people, so results may not apply to everyone. The vaccine may not reduce recurrence and could cause side effects like injection site reactions.
