IBI351 Plus Cetuximab β in Untreated Advanced Non-small Cell Lung Cancer With KRAS G12C Mutation
China48 participantsStarted 2025-11-03
Plain-language summary
Study Design: a Phase II, single-arm, multicenter, prospective, interventional study.
Target Population: Subjects with previously untreated, locally advanced or metastatic non-small cell lung cancer (NSCLC) confirmed to harbor the KRAS G12C mutation.
Treatment Regimen: All enrolled subjects will receive IBI351 combined with cetuximab β injection. Treatment will continue until disease progression (as assessed by the investigator per RECIST 1.1 criteria) or the occurrence of intolerable toxicity.
Primary Endpoint: Objective Response Rate (ORR) as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
Secondary Endpoints: Disease Control Rate (DCR), Time to Response (TTR), Progression-Free Survival (PFS), and Overall Survival (OS) , and safety.

. Life expectancy ≥ 3 months.
. Histologically or cytologically confirmed unresectable locally advanced (Stage IIIB/IIIC), metastatic, or recurrent (Stage IV) non-small cell lung cancer (NSCLC), per the International Association for the Study of Lung Cancer (IASLC) and American Joint Committee on Cancer (AJCC) 8th edition TNM staging, and not candidates for curative concurrent chemoradiotherapy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Objective Response Rate
Timeframe: From the first dose of treatment to disease progression or death, whichever comes first, up to 2 years
. No prior systemic anti-tumor therapy for locally advanced or metastatic non-squamous NSCLC. Subjects who received prior adjuvant therapy are eligible provided disease recurrence occurred ≥6 months after the last dose of adjuvant therapy or the last session of radical radiotherapy.
. At least one measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Lesions within a prior radiation field or after local therapy can be considered target lesions if documented progression is evident.
Exclusion criteria
. Histologically or cytologically confirmed NSCLC with mixed small cell components or predominantly squamous cell carcinoma components.
. Presence of EGFR sensitizing mutation, ALK rearrangement, ROS-1 fusion, or other genomic alterations for which NMPA-approved first-line NSCLC therapies exist.
. Significant cardiovascular or cerebrovascular disease, including:
. Active infection requiring systemic therapy.
. Baseline positive HIV antibody (HIV-Ab); acute or chronic active hepatitis B (defined as HBsAg and/or HBcAb positive AND HBV-DNA \> 2500 copies/mL or 500 IU/mL); or acute or chronic active hepatitis C (HCV antibody positive AND HCV-RNA above the lower limit of quantification).
. Active pulmonary tuberculosis. 8. Symptomatic pleural, peritoneal, or pericardial effusions requiring repeated drainage.
