The purpose of this Expanded Access Program is to provide investigational ALK inhibitor, neladalkib (NVL-655), for eligible patients with ALK-positive locally advanced or metastatic NSCLC (ALK+ NSCLC) who have previously received an ALK tyrosine kinase inhibitor (TKI) or eligible patients with other ALK-positive solid tumors, and lack satisfactory therapeutic alternatives and are unable to access neladalkib through a clinical trial.
