Can a cancer drug stop nerve tumors before they cause harm?

NCT ID NCT06188741

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether giving selumetinib early to children with NF1, before nerve tumors cause symptoms, can prevent tumor growth and related problems. About 200 children aged 1 to 8 years with no known tumors will either receive the drug or be observed. The goal is to see if early treatment improves progression-free survival.

What this could mean

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

Active substance
Selumetinib (Koselugo)
What this could lead to
If successful, this could show that starting treatment early prevents serious complications like blindness or nerve damage in children with NF1.
What could go wrong
This is a Phase 2 trial, so it is still early. The drug may not prevent tumor growth better than observation, and side effects like nausea or skin rash are possible.
