Olomorasib + Pembrolizumab KRAS G12C Mutant, PD-L1 TPS 1-49% Locally Advanced or Metastatic NSCLC
This clinical trial evaluates the combination of olomorasib and pembrolizumab as a first-line treatment for patients with advanced or metastatic non-small cell lung cancer (NSCLC) that has a Kirsten Rat Sarcoma Virus (KRAS) G12C mutation and a programmed death-ligand (PD-L1) score between 1% and 49%. The main goal of the study is to determine how long patients live without their cancer worsening after starting treatment, also known as progression-free survival (PFS). Additional goals include evaluating how many patients experience tumor shrinkage or disappearance, how long responses to treatment last, overall survival, and the safety and side effects of the treatment combination. Furthermore, how well the treatment works in patients whose cancer has spread to the brain, outcomes in patients with a lower Eastern Cooperative Oncology Group performance status (ECOG), and whether certain tumor or blood-based biomarkers are associated with treatment response or side effects, if enough patient data is available for analysis.

Who may be able to participate
The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.
- In order to participate in this study a subject must meet all of the eligibility criteria outlined below. Eligibility must be maintained up until the point at which the subject receives treatment for the subject to be considered eligible for treatment. In order to participate in this study a subject must meet ALL of the eligibility criteria outlined below. Written informed consent obtained to participate in the study and HIPAA authorization for release of personal health information. Subject is willing and able to comply with study procedures based on the judgement of the investigator.
- Age ≥ 18 years at the time of consent.
- Eastern Cooperative Oncology Group performance status (ECOG) of 0-2
- Subjects must have previously untreated, Stage IIIB-IIIC or Stage IV Non-Small Cell Lung Cancer (NSCLC) not amenable to curative intent treatment.
- Measurable disease according to Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1 within 28 days prior to treatment
- Known KRAS G12C mutation identified on tumor tissue or circulating tumor DNA (ctDNA) as determined by molecular testing performed in a CLIA, CAP or other similarly certified laboratory per local guidelines.
- Subjects must have a known PD-L1 tumor proportion score (TPS) of 1-49% as determined by an IHC assay in a CLIA, CAP, or other similarly certified laboratory as per local guidelines
Subject has a serious pre-existing medical condition(s) that, in the judgment of the Investigator, would preclude participation in this study, including interstitial lung disease (ILD) or severe dyspnea at rest and uncontrolled disease-related pericardial effusion or pleural effusion.
Important: This is the sponsor’s public criteria, not a determination of eligibility. The study team must review your individual situation.
