Detailed Description
This is a multicenter, open-label study of SKB264 as combination therapy in subjects with NSCLC. Approximately up to 296 subjects will be enrolled in this study including around 36 (may expand) subjects for safety run-in period and 200 subjects for expansion period.

Outcome Measures
Primary Outcome Measures
- Safety and tolerability [From subject sign the informed consent form (ICF) to 30 days after the last dose of study treatment, up to approximately 36 months]
Dose-limiting toxicity (DLT); Incidence and severity of adverse events (AEs); Discontinuation of study treatment due to AEs
- ORR [The proportion of subjects with a confirmed complete response (CR) or partial response (PR), up to approximately 36 months]
Objective response rate (ORR) per RECIST v1.1
Secondary Outcome Measures
- Duration of response (DOR) [From baseline until disease progression, death, or other protocol defined reason, up to approximately 36 months]
For subjects with a confirmed CR or PR, DOR is defined as the time from the first documented evidence of CR or PR until radiographic disease progression or death due to any cause, whichever occurs first
- Progression-free survival (PFS) [From baseline until disease progression, death, or other protocol defined reason, up to approximately 36 months]
The time from first dose of study intervention to first documentation of radiographic disease progression or death due to any cause, whichever occurs first
- Overall survival (OS) [From baseline until death due to any cause, up to approximately 36 months]
the time period from the start of study intervention to death due to any cause.
