Summary

This early-phase trial tests a personalized oral DNA cancer vaccine (NECVAX-NEO1) given alongside standard immunotherapy drugs in 20 adults with solid tumors. The vaccine is designed to target unique markers on each patient's cancer. The study aims to check safety and whether the combination can help control tumor growth. Participants must already be on immunotherapy and have stable or responding disease.

What this could mean

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

Active substance

Personalized oral DNA cancer vaccine (NECVAX-NEO1) plus standard immunotherapy (PD-1/PD-L1 inhibitors)

What this could lead to

If successful, this could offer a new way to boost the immune system's ability to fight solid tumors, potentially improving tumor control when combined with standard immunotherapy.

What could go wrong

This is an early-phase trial with only 20 participants, so results may not apply to all patients. The vaccine is personalized, which is complex and may not work for everyone. Side effects from the combination therapy are possible.
