NCT ID NCT05077709

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tested a new cancer vaccine (IO102-IO103) combined with the immunotherapy drug pembrolizumab as a first treatment for people with advanced lung, head/neck, or bladder cancer that had spread. The study enrolled 63 participants to see if the combination is safe and effective at shrinking tumors. Results will help determine if this approach deserves further study.

What this could mean

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

Active substance

IO102-IO103 (a cancer vaccine) combined with pembrolizumab (an immunotherapy drug)

What this could lead to

If successful, this combination could offer a new first-line treatment option for people with these advanced cancers, potentially improving response rates and delaying disease progression.

What could go wrong

This is an early-phase trial with only 63 participants, so results may not apply broadly. The combination may cause immune-related side effects, and not all patients may benefit.
