Polio virus turned against skin cancer in new trial

NCT ID NCT04577807

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This Phase 2 trial tested a modified polio virus called lerapolturev, alone or combined with an immunotherapy drug, in 27 adults with advanced melanoma that had stopped responding to standard PD-1 therapy. The virus was injected directly into tumors to trigger an immune attack. Researchers measured tumor shrinkage, side effects, and survival. The goal was to see if this approach could offer a new option for hard-to-treat melanoma.

What this could mean

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

Active substance

Lerapolturev (a modified polio virus) and an anti-PD-1 checkpoint inhibitor (immunotherapy drug)

What this could lead to

If successful, this could offer a new treatment option for people with advanced melanoma that no longer responds to standard immunotherapy.

What could go wrong

This is a small, early-phase trial with only 27 participants, so results may not apply to everyone. The virus-based therapy may cause side effects or fail to shrink tumors.
