Phase I/II ARROS-1 Study of Zidesamtinib (NVL-520) in ROS1 Fusion-positive Solid Tumours

The ARROS-1 Phase 1/2 study investigates the safety, tolerability, and efficacy of zidesamtinib (NVL-520), a ROS1-selective, brain-penetrant tyrosine kinase inhibitor, in heavily pre-treated patients with ROS1 fusion-positive non-small cell lung cancer (NSCLC) and other solid tumors, showing promising durable responses in both systemic and intracranial disease.
