Plain-language summary

The main objective of this study is to evaluate the tumor objective response rate (ORR) assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria in participants who receive sotorasib at either 960 mg daily or 240 mg daily whose tumors are programmed death-ligand 1 (PD-L1) Tumor Proportion Score (TPS) \< 1% and/or harbor a serine/threonine kinase 11 (STK11) co-mutation, in a subgroup of participants with PD-L1 \< 1% and in a subgroup of participants with STK11 co-mutation.

Inclusion Criteria: * Adult (= or \> 18 years old) with NSCLC * Untreated Stage IV metastatic disease. Participants who received adjuvant or neoadjuvant anti-tumor therapy are eligible if the adjuvant/neoadjuvant therapy was completed greater than 12 months prior to the development of metastatic stage IV disease * Pathologically documented metastatic NSCLC with KRAS G12C mutation (local confirmation) * Programmed death-ligand 1 (PD-L1) TPS Score \< 1% and/or serine/threonine kinase 11 (STK11) co-mutation (local confirmation) * Eastern Cooperative Oncology Group (ECOG) score of 0 or 1 * No active brain metastases * Measurable disease per investigator interpretation using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria Exclusion Criteria: * Mixed small-cell lung cancer and NSCLC histology * Myocardial Infarction within 6 months of study Day 1 * Use of proton-pump inhibitors (PPIs), histamine (H2) receptor antagonists (H2RA), strong inducers of cytochrome P450 (CYP) 3A4 (CYP3A4) or known CYP3A4 sensitive substrates or P-gp substrates * Therapeutic or palliative radiation therapy within 2 weeks of study day 1 * Unable to take oral medication * Unable to receive both iodinated contrast for computed tomography (CT) scans and gadolinium contrast for magnetic resonance imagine (MRI) scans

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
