What studies found

In INTerpath-001 (1,137 patients with resected high-risk melanoma), intismeran plus pembrolizumab lowered recurrence and distant spread versus pembrolizumab alone; reported at ESMO 2026 as about a 42% lower risk of recurrence or death.

The catch

Survival data are not yet mature, it is proven only in melanoma, and it awaits regulatory review.

What to do

Ask about clinical trials if you have high-risk melanoma or another cancer being studied.
