Efficacy and Safety of IBI351 in Combination With Sintilimab ± Chemotherapy in Advanced Non-squamous Non-small Cell Lung Cancer Subjects With KRAS G12C Mutation

Phase 1

Recruiting

• Conditions: Advanced Non-Small Cell Lung Cancer
• Interventions: Drug: pemetrexed; Drug: IBI351; Drug: cis-platinum; Drug: Sintilimab; Drug: carboplatin

• Registration Number: NCT05504278
• Lead Sponsor: Innovent Biologics (Suzhou) Co. Ltd.

Brief Summary

This Phase Ib/III study evaluates the efficacy and safety of IBI351 in combination with Sintilimab± chemotherapy in advanced non-squamous NSCLC with KRAS G12C mutation.

Detailed Description

This Phase Ib/III study evaluates the efficacy and safety of IBI351 in combination with Sintilimab± chemotherapy. There will be four cohorts of subjects, all of whom have KRAS G12C mutation and have advanced or metastatic NSCLC. Three cohorts (A, C and D) are treated with IBI351+Sintilimab, IBI351+Sintilimab+pemetrexed, or IBI351+Sintilimab+pemetrexed+cis-platinum/carboplatin, respectively, as first-line therapy. Cohort B enrolles subjects who is intolerant or has failed in standard-of care treatment,and is treated with IBI351+Cetuximab.

IBI351 is an orally available small molecule inhibitor of KRAS G12C.
