A Phase Ⅱ Clinical Study of Combination Therapy of SKB264 in Patients With Advanced or Metastatic Non-small Cell Lung Cancer.
Study Details
Study Description
Brief Summary
The purpose of this study is to assess the safety, tolerability and preliminary antitumor activity of SKB264 in combination with KL-A167 with or without chemotherapy with advanced or metastatic non-small cell lung cancer. The study is divided into two parts. Part 1 will be the safety run-in phase, and Part 2 will be the cohort expansion phase.

Outcome Measures
Primary Outcome Measures
- Incidence and severity of adverse events (AEs) [From signature completion of ICF to 30 days after the last dose or to the beginning of the new anti-cancer therapy, up to 24 months]
Incidence and severity of adverse events (AEs) graded by Common Terminology Criteria for Adverse Events (CTCAE) v5.0
- Objective Response Rate (ORR) [From the date of the first dose until disease progression or death (whichever occurs first), up to 24 months]
Objective Response Rate (ORR) is defined as the proportion of participants who achieved a best overall response (BOR) of complete response (CR) or partial response (PR), evaluated based on RECIST v1.1 criteria
Secondary Outcome Measures
- Progression-free survival (PFS) [From the date of the first dose until disease progression or death (whichever occurs first), up to 24 months]
- Duration of response (DOR) [From first objective response ( CR or PR) to PD or death (whichever occurs first), up to 24 months]
- Disease control rate (DCR) [From the date of the first dose to the date of the firstly documented disease progression (evaluated based on RECIST v1.1 criteria) or the date of death for any reason, up to 24 months]
- Pharmacokinetic Parameter Maximum Plasma Concentration (Cmax) of SKB264-ADC, SKB264-TAB and free KL610023 [Cycle 1-8, every 4 cycles starting from Cycle 12 Day 1: pre-dose, post-dose (each cycle is 21 days), up to 24 months]
- Pharmacokinetic Parameter Minimum Plasma Concentration (Cmin) of SKB264-ADC, SKB264-TAB and free KL610023 [Cycle 1-8, every 4 cycles starting from Cycle 12 Day 1: pre-dose, post-dose (each cycle is 21 days), up to 24 months]
- Pharmacokinetic Parameter Maximum Plasma Concentration (Cmax) of KL-A167 [Cycle 1-8, every 4 cycles starting from Cycle 12 Day 1: pre-dose, post-dose (each cycle is 21 days), up to 24 months]
- Pharmacokinetic Parameter Minimum Plasma Concentration (Cmin) of KL-A167 [Cycle 1-8, every 4 cycles starting from Cycle 12 Day 1: pre-dose, post-dose (each cycle is 21 days), up to 24 months]
- Anti-drug Antibodies (ADA) for SKB264 and KL-A167 [Cycle 1-8, every 4 cycles starting from Cycle 12 Day 1: pre-dose, post-dose (each cycle is 21 days), up to 24 months]
