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
Exclusion Criteria
- Known concomitant second oncogenic driver with available targeted treatment
- Squamous cell histology NSCLC
- Symptomatic, untreated, or actively progressing central nervous system (CNS) metastases
- 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

Group Intervention Description Cohort B - Combination Dose Finding + Dose Expansion Pembrolizumab Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) QD combined with pembrolizumab 200 mg IV Q3W plus investigator's choice of platinum-based chemotherapy (carboplatin or cisplatin) and pemetrexed. Cohort B - Combination Dose Finding + Dose Expansion Divarasib Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) QD combined with pembrolizumab 200 mg IV Q3W plus investigator's choice of platinum-based chemotherapy (carboplatin or cisplatin) and pemetrexed. Cohort A - Combination Dose Finding + Dose Expansion Pembrolizumab Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) once a day (QD) combined with pembrolizumab 200 mg intravenous (IV) infusion every 3 weeks (Q3W). During the expansion stage, some participants are planned to be randomized to one divarasib combination dose level; other participants are planned to be randomized to another divarasib combination dose level. Divarasib will be given in combination with pembrolizumab. Cohort B - Combination Dose Finding + Dose Expansion Carboplatin Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) QD combined with pembrolizumab 200 mg IV Q3W plus investigator's choice of platinum-based chemotherapy (carboplatin or cisplatin) and pemetrexed. Cohort B - Combination Dose Finding + Dose Expansion Cisplatin Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) QD combined with pembrolizumab 200 mg IV Q3W plus investigator's choice of platinum-based chemotherapy (carboplatin or cisplatin) and pemetrexed. Cohort B - Combination Dose Finding + Dose Expansion Pemetrexed Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) QD combined with pembrolizumab 200 mg IV Q3W plus investigator's choice of platinum-based chemotherapy (carboplatin or cisplatin) and pemetrexed. Cohort A - Combination Dose Finding + Dose Expansion Divarasib Participants enrolled in this cohort will receive divarasib (different dose levels will be evaluated) once a day (QD) combined with pembrolizumab 200 mg intravenous (IV) infusion every 3 weeks (Q3W). During the expansion stage, some participants are planned to be randomized to one divarasib combination dose level; other participants are planned to be randomized to another divarasib combination dose level. Divarasib will be given in combination with pembrolizumab.
- Primary Outcome Measures
Name Time Method Percentage of Participants with Adverse Events (AEs) 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 3 years)
- Secondary Outcome Measures
Name Time Method Objective Response Rate (ORR) Up to approximately 3 years The percentage of participants who experience a complete response or partial response, as determined by the investigator, according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
Duration of Response (DOR) Up to approximately 3 years The time from the first occurrence of a documented objective response to disease progression or death from any cause (whichever occurs first), as determined by the investigator according to RECIST v1.1
Number of Participants Reporting Presence, Frequency, Severity, and/or Degree of Interference with Daily Function of Symptomatic Side Effects as Assessed Through the Patient-Reported Outcomes Common Terminology Criteria for Adverse Events (PRO-CTCAE) Up to approximately 3 years Progression Free Survival (PFS) Up to approximately 3 years The time from randomization, or date of first treatment for participants enrolled prior to the expansion stage, to the first occurrence of disease progression or death from any cause during the study (whichever occurs first), as determined by the investigator according to RECIST v1.1
Frequency of Participant's Response of the Degree they are Troubled with Treatment Symptoms, as Assessed Through use of the Single-item European Organisation for Research and Treatment of Cancer (EORTC) Item List 46 (IL46) Up to approximately 3 years Change from Baseline in Symptomatic Side Effects, as Assessed Through use of the PRO-CTCAE Baseline up to approximately 3 years Percentage of Participants Reporting "Frequent" or "Almost Constant" Diarrhea During the First Three Cycles of Treatment According to the PRO-CTCAE Criteria Up to approximately 3 years Percentage of Participants Reporting "Severe" or "Very Severe" Nausea or Vomiting During the First Three Cycles of Treatment According to the PRO-CTCAE Up to approximately 3 years Plasma Concentration of Divarasib at Specified Timepoints At Days 1, 8 and 15 of Cycles 1 and 2; Days 1 and 15 of Cycles 3 and 4; Day 1 of every other Cycle after Cycle 5, until treatment discontinuation (up to approximately 3 years). Each cycle is 21 days. Identification of Divarasib Recommended Dose Up to approximately 3 years The recommended dose will be based upon the totality of safety, activity, and PK data.
