Withdrawn proactively due to the company's development strategy adjustment and changes in the drug R&D direction.

This is a phase II, Single-arm,Open-label Study evaluating the safety and efficacy of CT053PTSA in Advanced Solid Tumors With MET Exon 14 Skipping Mutations

This study is being carried out in two parts, part 1 and part 2. Part 1:Observation phase of dose tolerance: Objective To observe the tolerability and safety of 60 mg CT053PTSA in advanced NSCLC patients with Metex14 skipping mutation, and to determine the recommended dose (RED) in the dose expansion phase。 Part 2: This is the expansion part and will continue to evaluate the safety and efficacy of CT053PTSA at the dose of RED in advanced NSCLC patients with Metex14 skipping mutation.
