Inclusion criteria

Key Inclusion Criteria: 1. Histologically or cytologically confirmed NSCLC that is locally advanced (Stage ⅢB/ⅢC) or metastatic (Stage IV) NSCLC that is not amenable to radical surgery and/or radical radiotherapy regardless of concurrent chemotherapy. 2. No prior systemic anti-cancer therapy for locally advanced or metastatic disease. 3. Participants whose tumours are PD-L1 TPS ≥ 1%. 4. At least one measurable lesion per RECIST v1.1. 5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 with no worsening within 7 days prior to randomization. 6. A life expectancy of at least 12 weeks. 7. Adequate organ and bone marrow function.

Design outcomes

Primary

MeasureTime frameDescription
Progression Free Survival (PFS) assessed by Blinded Independent Central Review (BICR)Randomization up to approximately 22monthsPFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 based on BICR or death due to any cause, whichever occurs first.

Secondary

MeasureTime frameDescription
Overall Survival (OS)Randomization up to approximately 40 monthsOS is defined as the time from randomization until the date of death due to any cause.
Progression-Free Survival (PFS) assessed by InvestigatorRandomization up to approximately 22monthsPFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 based on investigator or death due to any cause, whichever occurs first.
Objective Response Rate (ORR)Randomization up to approximately 22monthsORR is defined as the percentage of patients who achieve complete response(CR) or partial response (PR), as assessed by BICR/investigator per RECIST 1.1
Disease control rate (DCR)Randomization up to approximately 22monthsDCR is defined as the percentage of patients who achieve CR, PR or stable disease (SD), as assessed by BICR/ investigator per RECIST 1.1
Duration of Response (DoR)Randomization up to approximately 22monthsDoR is defined as the time from the date of first documented CR or PR until date of documented disease progression per RECIST 1.1, as assessed by BICR/investigator or death due to any cause, whichever occurs first.
Time to Response (TTR)Randomization up to approximately 22monthsTTR is defined as the time from the date of randomization until the first documentation of CR or PR as assessed by BICR/investigator per RECIST 1.1.
Health-Related Quality of Life AssessmentRandomization up to approximately 22monthsCompare the health-related quality of life (HRQoL) of SKB264 in combination with pembrolizumab and pembrolizumab monotherapy by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 (EORTC QLQ-C30) and Quality of Life Questionnaire - Lung Cancer Module 13 (EORTC QLQ-LC13)
AEs and SAEsAll AEs should be observed and recorded from the first dose until 30 days after the last dose. SAEs were observed and recorded until 90 days after the last dose of pembrolizumab or 30 days after the last dose of SKB264,whichever occurred later.Incidence and severity of AEs and SAEs (per CTCAE v5.0), and clinically significant abnormal laboratory results
PKRandomization up to approximately 22monthsPK parameters of SKB264-ADC, SKB264-TAB and free KL610023, such as maximum concentration (Cmax), minimum concentration (Cmin ), etc.
ImmunogenicityRandomization up to approximately 22monthsImmunogenicity test results of SKB264
BiomarkersTumor tissue samples should be provided for TROP2 testing after subjects are eligible for screening.Correlation between the expression level of TROP2 in tumor tissues and the efficacy.
