This Expanded Access Program will provide access of taletrectinib therapy to patients with locally advanced or metastatic c-ros-oncogene 1 (ROS1)-positive non-small cell lung cancer (NSCLC). These patients are not an appropriate candidate for an approved therapy, including crizotinib, entrectinib, or repotrectinib, for participating in ongoing Nuvation Bio clinical trial AB-106-G208 and who, in the opinion of their oncologist, may benefit from treatment.
