本研究的目的是评估divarasib和pembrolizumab与pembrolizumab、培美曲塞和卡铂或顺铂相比，对KRAS G12C突变、晚期或转移性非鳞状非小细胞肺癌(NSCLC)成人参与者的一线治疗的有效性和安全性。
适应症：Non-Small Cell Lung Cancer、KRAS G12C Lung Cancer

- Eligible to receive a platinum-based chemotherapy regimen
排除标准
- Known concomitant second oncogenic driver with available targeted treatment
- Symptomatic, untreated, or actively progressing central nervous system (CNS) metastases
- Spinal cord compression not definitively treated with surgery and/or radiation or previously diagnosed and treated spinal cord compression without evidence that disease has been clinically stable for \>=2 weeks prior to randomization
- History of leptomeningeal disease
- Uncontrolled tumor-related pain
- Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures (once a month or more frequently)
- Any anti-cancer systemic therapy, including hormonal therapy, within 21 days prior to randomization, or is expected to require any other form of antineoplastic therapy while in the study
- Radiation therapy including palliative RT to bone metastases within 2 weeks prior to randomization and RT to the lung \>30Gy within 6 months prior to randomization
- Prior treatment with KRAS G12C inhibitors or pan-KRAS/RAS inhibitors
- Treatment with systemic immunosuppressive or immunostimulatory medications, including CD137 agonists and immune checkpoint inhibitors

- History of malignancy other than NSCLC within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death (e.g., 5-year overall survival \[OS\] rate \>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
- Individuals with chronic diarrhea, short bowel syndrome or significant upper gastrointestinal surgery including gastric resection, a history of inflammatory bowel disease (e.g., Crohn's disease or ulcerative colitis) or any active bowel inflammation (including diverticulitis), malabsorption syndrome, conditions that would interfere with enteral absorption
