Zidesamtinib (NVL-520) was approved by the FDA on July 22, 2026 for ROS1 Non-small cell lung cancer (NSCLC), the 27th novel drug approval of 2026 on the FDA's Novel Drug Approvals list.
JIDEYTRO (zidesamtinib), a ROS1-selective TKI, approved on July 22, 2026 for previously treated ROS1-positive NSCLC - 58 days ahead of its September 18 PDUFA goal date.
The PDUFA target action date was September 18, 2026; the FDA approved zidesamtinib on July 22, nearly two months early. Efficacy came from ARROS-1, a multicenter, single-arm, open-label, multi-cohort trial in 117 patients: 59 who had received one prior ROS1 TKI and 58 who had received two or more, including lorlatinib, repotrectinib and/or taletrectinib. Zidesamtinib held Breakthrough Therapy and Orphan Drug designations. Nuvalent is partnered with GSK, which announced the approval alongside the FDA notice.
