Combining IBI351 with chemotherapy for advanced lung cancer with KRAS G12C mutation

An Open-label, Multi-center Phase Ib/III Study Evaluating the Efficacy and Safety of IBI351 in Combination With Chemotherapy in Advanced or Metastatic Non-squamous Non-small Cell Lung Cancer Subjects With KRAS G12C Mutation

Phase 1 Interventional Innovent Biologics (Suzhou) Co. Ltd. · NCT05504278

This study is testing if a new drug called IBI351 can work better with chemotherapy for people with advanced lung cancer that has a specific KRAS G12C mutation.

What this trial studies

This Phase Ib/III study evaluates the efficacy and safety of IBI351, a small molecule inhibitor, in combination with various chemotherapy regimens for patients with advanced non-squamous non-small cell lung cancer (NSCLC) harboring the KRAS G12C mutation. The study includes five treatment cohorts, each receiving different combinations of IBI351 with chemotherapy agents such as pemetrexed, carboplatin, and Cetuximab. Participants must have unresectable or metastatic disease and have not previously received systemic antitumor therapy for their condition.

Who should consider this trial

Good fit: Ideal candidates are individuals with unresectable or metastatic non-squamous NSCLC who have a confirmed KRAS G12C mutation and have not undergone prior systemic therapy.

Not a fit: Patients with active brain metastases or those who have previously received treatment targeting the KRAS G12C mutation may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with advanced lung cancer that has limited treatment alternatives.

How similar studies have performed: Other studies targeting KRAS mutations have shown promise, indicating potential for success with this novel approach.
