GSK plc GSK announced that the FDA has approved Jideytro (zidesamtinib) for previously treated ROS1-positive non-small cell lung cancer (NSCLC). Jideytro was added as a late-stage candidate to GSK’s oncology portfolio through the recently closed acquisition of Nuvalent.
Jideytro is a next-generation, highly selective ROS1 inhibitor and has become GSK's first approved therapy for lung cancer.
The regulatory authority granted approval nearly one month ahead of the original PDUFA target date of Sept.18, 2026, enabling an earlier-than-expected commercial launch.
Year to date, GSK’s shares have risen 5.3% compared with the industry’s 3% growth.

FDA Approval Backed by GSK’s ARROS-1 Phase I/II Study
The FDA approval of Jideytro was based on data from the global phase I/II ARROS-1 study, which evaluated Jideytro in patients with advanced or metastatic ROS1-positive NSCLC previously treated with a ROS1 inhibitor. The study demonstrated durable clinical responses, including in patients with brain metastases and ROS1 resistance mutations.
In the overall study population, Jideytro achieved an objective response rate of 44% and response durability was maintained in most patients at both six and 12 months.
The safety profile was manageable, with the most common adverse events being edema, peripheral neuropathy, constipation, fatigue and dyspnea.
The ARROS-1 study remains ongoing and is continuing to evaluate Jideytro in additional patient populations, including as a first-line treatment for patients with ROS1-positive NSCLC who have not previously received a ROS1 inhibitor.
Acquisition of Jideytro Strengthens GSK's Precision Oncology Franchise
The Nuvalent acquisition strengthened GSK's growing oncology business by adding a portfolio of targeted therapies for genetically defined forms of NSCLC.
Beyond Jideytro, GSK's acquired pipeline includes neladalkib, an investigational ALK inhibitor currently under FDA review with a PDUFA target date of Nov. 27, 2026, and NVL-330, a HER2-targeted therapy that is being evaluated in phase I studies for HER2-altered NSCLC.
