New ALK inhibitor NVL-655 enters trials for Hard-to-Treat cancers
NCT ID NCT05384626
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug called neladalkib (NVL-655) in people with advanced ALK-positive non-small cell lung cancer and other solid tumors. The trial has two parts: Phase 1 finds the safest dose, and Phase 2 checks how well it shrinks tumors. Up to 840 participants will be enrolled.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Neladalkib (NVL-655)
- What this could lead to
- If successful, this could provide a new treatment option for people with ALK-positive cancers that have stopped responding to other therapies.
- What could go wrong
- This is an early-phase trial, so the drug may not work as hoped or could cause unexpected side effects. Results may not apply to all patients.
