• Conditions: Locally Advanced or Metastatic NSCLC
• Interventions: Drug: ASKC202+ Limertinib; Drug: Pemetrexed + Cisplatin /Carboplatin

• Registration Number: NCT07109531
• Lead Sponsor: Jiangsu Aosaikang Pharmaceutical Co., Ltd.

Brief Summary

This study is designed to compare the safety and efficacy of ASKC202 combined with Limertinib Versus platinum-based chemotherapy in locally advanced or metastatic NSCLC With MET Amplification/Overexpression after disease progression on EGFR tyrosine kinase inhibitor.

Detailed Description

This is a randomized, controlled, open-label, multicenter, phase 3 clinical study to valuate the efficacy and safety of ASKC202 combined with Limertinib in locally advanced or metastatic NSCLC with MET amplification/overexpression after failure of EGFR inhibitor therapy. Participants will continue to receive treatment until disease progression, intolerable toxicity, withdrawal of informed consent, death, or any other reasons for treatment discontinuation, whichever occurs first.

Primary Outcome Measures

Name	Time	Method
Progression-Free Survival (PFS) by BIRC	2 years	Progression-free survival (PFS) using BIRC assessment as defined by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1).Progression-free survival was defined as the time from date of randomization until the documentation of objective disease progression (PD) or death from any cause in the absence of progression (whichever occurred first).

Secondary Outcome Measures

Name	Time	Method
Progression-free survival (PFS) by investigator	2 years	Progression-free survival (PFS) using Investigator assessment as defined by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1).Progression-free survival was defined as the time from date of randomization until the documentation of objective disease progression (PD) or death from any cause in the absence of progression (whichever occurred first).
Overall Survival (OS)	3 years	The time from the date of randomization to the date of death .
Objective Response Rate (ORR)	2 years	ORR was defined as the percentage of participants with complete response (CR) or partial response (PR) .
Disease Control Rate (DCR)	2 years	DCR was defined as the percentage of participants with complete response(CR), partial response(PR) and stable disease(SD).
Duration of Response (DoR)	2 years	Duration of response was defined as the time from when the criteria for CR or PR were first met to the occurrence of an objective disease progression or death.
Incidence and severity of treatment-emergent adverse events	2 years	Assessed by number and severity of adverse events as recorded on the case report form NCI CTCAE v5.0.
