Phase 2 |
Detailed Description
This study will explore the treatment of locally advanced or metastatic non-small cell lung cancer with HER2 mutation, amplification, or HER2 mutation (mutation, amplification, protein over-expression) using Disitamab Vedotin（RC48） combined with Tislelizumab or third-generation EGFR-TKI Furmonertinib, in the aim of providing new treatment strategies for lung cancer patients with HER2 pathway activation.

Outcome Measures
Primary Outcome Measures
- Percentage of Participants With Objective Response Rate (ORR) Based on Investigator Assessment Following Treatment in Participants With HER2 alterations Non-Small-Cell Lung Cancer (NSCLC) [Up to 24 months (data cut-off)]
Percentage of Participants who have a complete response (CR) or partial response (PR) as assessed by investigator according to RECIST 1.1
Secondary Outcome Measures
- Disease control rate (DCR) Following Treatment in Participants With HER2 alterations Non-Small-Cell Lung Cancer (NSCLC) [Up to 24 months (data cut-off)]
Defined as the proportion of participants who have a complete response (CR), partial response (PR) or standard disease (SD) as assessed by investigator according to RECIST 1.1
- Progression-free survival (PFS) Following Treatment in Participants With HER2 alterations Non-Small-Cell Lung Cancer (NSCLC) [Up to 24 months (data cut-off)]
Defined as time from randomization until progression per RECIST 1.1 as assessed by investigator, or death due to any cause.
- Duration of Response (DoR) Following Treatment in Participants With HER2 alterations Non-Small-Cell Lung Cancer (NSCLC) [Up to 24 months (data cut-off)]
Defined as the time from the date of first documented response until date of documented progression as assessed by investigator assessment according to RECIST 1.1.
- Overall Survival (OS) Following Treatment in Participants With HER2 alterations Non-Small-Cell Lung Cancer (NSCLC) [Up to 24 months (data cut-off)]
Defined as time from randomization until the date of death due to any cause.
