This is a single-arm, open, multicenter exploratory clinical trial to observe and evaluate the efficacy and safety of Iruplinalkib Tablets in patients with ROS1 positive non-small cell lung cancer.

Iruplinalkib Tablets should be administered orally at a roughly fixed time each day. Once daily, on an empty stomach or with food, 60mg per dose for days 1 to 7, 180 mg per dose from day 8 if tolerated. Swallow the tablet whole, do not crush, divide or chew the tablet.

The primary end point was objective response rate
