Researchers want to learn if MK-1084, the study medicine, can treat advanced or metastatic non-squamous NSCLC. MK-1084 is a targeted therapy, which is a treatment that works to control how specific types of cancer cells grow and spread. The goals of this study are to learn:
* About the safety of MK-1084 and if people tolerate it when taken with other treatments * How many people have the cancer respond (get smaller or go away) to the treatments
Has histologically or cytologically confirmed diagnosis of advanced or metastatic non-squamous non-small cell lung cancer (NSCLC)
Has tumor tissue or circulating tumor deoxyribonucleic acid (ctDNA) that demonstrates the presence of Kirsten rat sarcoma viral oncogene (KRAS) mutation of glycine to cysteine at codon 12 (G12C) mutations
Has documented disease progression after receiving 1-2 prior lines of programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) therapy and platinum-based chemotherapy
Has provided tumor tissue for biomarker analysis from an archival sample or a newly obtained core or excisional biopsy of a tumor lesion not previously irradiated
Has a diagnosis of small cell lung cancer or, for mixed tumors, presence of small cell elements
Has clinically severe pulmonary compromise resulting from intercurrent pulmonary illnesses
Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis
Has active inflammatory bowel disease requiring immunosuppressive medication or previous history of inflammatory bowel disease

Rescue Medications
DrugParticipants receive rescue medication at the investigator's discretion for prevention of nausea and vomiting, per approved product label. Recommended rescue medications are histamine-1 (H1) receptor antagonist, histamine-2 (H2) receptor antagonist, acetaminophen or equivalent, dexamethasone or equivalent infusion, or steroid mouthwash (dexamethasone or equivalent), 5-hydroxytryptamine type 3 (5-HT3) receptor antagonist, neurokinin 1 (NK-1) receptor antagonist and corticosteroid.
Number of Participants Who Experience a Dose Limiting Toxicity (DLT)
DLT will be defined as any drug-related AE observed during the DLT evaluation period (up to 42 days) that results in a change to a given dose or a delay in initiating the next treatment.
Number of Participants Who Experience an Adverse Event (AE)
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants that experience AEs will be reported.
Number of Participants Who Discontinue Study Treatment Due to an AE
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants that discontinue study intervention due to an AE will be reported.
Objective Response Rate (ORR)
ORR is defined as the percentage of participants with Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1). The percentage of participants who experience CR or PR as assessed by Blinded Independent Central Review (BICR) will be presented.
Duration of Response (DOR)
For participants who demonstrate a confirmed CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. DOR as assessed by BICR will be presented.
Progression-Free Survival (PFS)
PFS is defined as the time from randomization to the first documented PD or death due to any cause, whichever occurs first as assessed by RECIST 1.1. PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by BICR will be presented.
Area Under the Curve From Time 0 to the End of the Dosing Interval (AUC tau)
Blood samples will be collected at multiple time points to estimate AUC tau.
Maximum Plasma Concentration (Cmax)
Blood samples will be collected at multiple time points to estimate Cmax.
