AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with advanced or metastatic non-squamous non-small cell lung cancer that has a KRAS G12C mutation and has grown again after earlier treatment.

Age
18 years or older
Sex
All sexes
Disease stage
Advanced or metastatic non-squamous non-small cell lung cancer, confirmed by tissue or cell examination
Earlier treatment
The cancer must have grown after 1-2 earlier lines of PD-1/PD-L1 therapy and platinum-based chemotherapy
Biomarker or test result
KRAS G12C mutation shown in tumor tissue or in tumor DNA in the blood (ctDNA); tumor tissue must be provided for marker testing

Main reasons for not taking part

  • Small cell lung cancer, or a mixed tumor with small cell parts
  • Active brain or spinal fluid spread (CNS metastases or carcinomatous meningitis), or any leptomeningeal disease
  • Any history of interstitial lung disease or pneumonitis
  • Active or past inflammatory bowel disease needing immune-suppressing medicine
  • Another cancer that is growing or needed treatment in the past 3 years

Could this be for you?

Answer for yourself. This is not a decision: only the study team can say whether you can take part.

  • Which best describes your lung cancer?
  • Has your cancer come back or got worse during or after treatment with platinum chemotherapy?
  • Has the cancer spread to other parts of the body, or is it too advanced to be removed by surgery?
  • Has your cancer spread to the brain?
  • Has your cancer spread to the lining around the brain or spinal cord?

KEYMAKER-U01 Substudy 01F: A Phase 1b/2 Umbrella Study With Rolling Arms of Investigational Agents for Previously Treated Participants With Advanced or Metastatic Nonsquamous Non-small Cell Lung Cancer (NSCLC) With KRAS G12C Mutations

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

Inclusion: The main inclusion criteria include but are not limited to the following:; 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; Participants with human immunodeficiency virus (HIV) infection must have well-controlled HIV on antiretroviral therapy (ART) per protocol.

Exclusion: Has active inflammatory bowel disease requiring immunosuppressive medication or previous history of inflammatory bowel disease; Has uncontrolled or significant cardiovascular disorder or cerebrovascular disease prior to allocation/randomization; Has received a live or live-attenuated vaccine within 30 days before the first dose of study intervention; Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study intervention; Has not adequately recovered from major surgery or has ongoing surgical complications; 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 evidence of any leptomeningeal disease; Has one or more of the following ophthalmological conditions: a) Clinically significant corneal disease b) history of documented severe dry eye syndrome, severe Meibomian gland disease and/or blepharitis; HIV-infected participants with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease; Has known additional malignancy that is progressing or has required active treatment within the past 3 years; Has any history of interstitial lung disease (ILD)/pneumonitis irrespective of steroid use or current ILD, or suspected ILD; Has an active infection requiring systemic therapy; The main exclusion criteria include but are not limited to the following:; Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
