Group 2: Clinical Trial Insights - The ARROS-1 Phase 1/2 clinical trial is currently investigating zidesamtinib in patients with advanced ROS1-positive NSCLC and other solid tumors, with the Phase 1 portion focusing on safety and tolerability [5]. - The ongoing Phase 2 portion is designed for TKI-naïve and TKI pre-treated patients, with registrational intent [5]. Group 3: Regulatory Engagement - The FDA has accepted the NDA for zidesamtinib under the Real-Time Oncology Review (RTOR) program, allowing for earlier submission of efficacy and safety results [2]. - The company is actively engaging with the FDA regarding potential opportunities for line-agnostic expansion [2]. Group 4: Market Need - There is a significant need for new treatment options for patients with ROS1-positive NSCLC, especially those who cannot tolerate existing TKIs or have disease progression with brain metastases or resistance mutations [3].
