Detailed Description

The purpose of this Expanded Access Program is to provide access to zidesamtinib (NVL-520) an investigational therapy for eligible patients with ROS1 fusion-positive advanced non- small cell lung cancer (ROS1+ NSCLC) who have previously received ≥ 1 prior ROS1 tyrosine kinase inhibitor (TKI) or eligible patients with other ROS1-positive solid tumors who have previously received any prior commercially-available or investigational therapy, and lack satisfactory therapeutic alternatives and are unable to access zidesamtinib through a clinical trial.
