Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the safety, tolerability and objective response rate of SKB264 as combination with therapy in subjects with advanced or metastatic non-small cell lung cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, open-label study of SKB264 as combination therapy or monotherapy in subjects with NSCLC. Approximately 498 subjects will be enrolled in this study including around 88 subjects for the safety run-in period and 410 subjects for the expansion period.
