An Open Label, Multi-center, Phase I Clinical Study to Evaluate the Safety, Effectiveness and Pharmacokinetic Characteristics of SIM1803-1A in Patients With Locally Advanced/Metastatic Solid Tumors With NTRK, ROS1 or ALK Gene Fusion Mutations.

September 21, 2026 updated by: Jiangsu Simcere Pharmaceutical Co., Ltd.

This research study is done to test the safety, effectiveness and pharmacokinetic characteristics of SIM1803-1A in patients with locally advanced/metastatic solid tumors with NTRK, ROS1 or ALK gene fusion mutations. The cancer must have a change in a particular gene (NTRK1, NTRK2, NTRK3, ROS1 or ALK). SIM1803-1A is a drug that blocks the actions of these NTRK/ ROS1 /ALK genes in cancer cells and can therefore be used to treat cancer.
