(KRAScendo 170)
What this study is about
The purpose of this study is to evaluate the safety, how the drug moves through the body (PK), and activity of divarasib combined with other anti-cancer therapies in participants with previously untreated, advanced or metastatic non-small cell lung cancer (NSCLC).

DRUG
Pembrolizumab
Participants will receive a 200 mg IV infusion of pembrolizumab Q3W on Day 1 of each 21-day cycle.
DRUG
Carboplatin
Participants will receive IV carboplatin Q3W for four 21-day cycles.
DRUG
Cisplatin
Participants will receive IV cisplatin Q3W for four 21-day cycles.
DRUG
Pemetrexed
Participants will receive IV pemetrexed Q3W.
Primary outcome measures
Percentage of Participants with Adverse Events (AEs)
Time frame: Baseline until 60 days after the final dose of study treatment or until initiation of another anti-cancer therapy, whichever occurs first (up to approximately 5 years)
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Confirmation of Biomarker eligibility
- Pre-treatment tumor tissue along with an associated pathology report is required for all participants enrolled on study. Representative tumor specimens must be in formalin-fixed, paraffin embedded (FFPE) blocks (preferred) or 15 unstained, freshly cut, serial slides. Although 15 slides are required, if only 10 slides are available, the participant may be eligible for the study following consultation with the Sponsor.
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1
- Histologically or cytologically documented locally advanced unresectable or metastatic NSCLC that is not eligible for curative surgery and/or definitive chemoradiotherapy
- No prior systemic treatment for advanced unresectable or metastatic NSCLC
- Measurable disease, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Additionally, for participants in cohort D, measurable brain metastases defined as at least 5 millimeters and twice the slice thickness, but less than 20 mm, that is asymptomatic and does not require local therapy at the time of enrollment.
Exclusion criteria
- Known concomitant second oncogenic driver with available targeted treatment
- Squamous cell histology NSCLC
- Symptomatic, untreated, or actively progressing CNS metastases (Cohorts A, B, and C)
- Prior treatment with a KRAS G12C inhibitor
- Known hypersensitivity to any of the components of divarasib or pembrolizumab; or known hypersensitivity to pemetrexed, carboplatin, or cisplatin (Cohort B only)
- History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis, active tuberculosis, significant cardiovascular disease within 3 months prior to initiation of study treatment
- History of malignancy other than NSCLC within 5 years prior to initiation of study treatment, with the exception of malignancies with a negligible risk of metastasis or death (e.g., 5-year OS rate more \>90%), such as adequately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, localized prostate cancer, ductal breast carcinoma in situ, or Stage I uterine cancer
- Uncontrolled tumor related pain, pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures, uncontrolled or symptomatic hypercalcemia
- Co-morbid condition that is an absolute contraindication to treatment with corticosteroids
- Inability or unwillingness to take prophylactic treatments such as corticosteroids, anti-emetics, folic acid, or vitamin B12 supplementation.
- Participants with brain metastases for whom complete surgical resections is clinically appropriate

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
