A Clinical Trial of Calderasib (MK-1084) and Durvalumab in People With Non-Small Cell Lung Cancer (MK-1084-015/KANDLELIT-015)
What this study is about
Researchers are looking for new ways to treat locally advanced non-small cell lung cancer (NSCLC) that is unresected and has a gene mutation called KRAS G12C. Researchers want to learn if calderasib (MK-1084) can be given with durvalumab, an immunotherapy, to treat NSCLC after chemotherapy and radiation therapy.
View original scientific description
Researchers are looking for new ways to treat locally advanced non-small cell lung cancer (NSCLC) that is unresected and has a gene mutation called KRAS G12C. Researchers want to learn if calderasib (MK-1084) can be given with durvalumab, an immunotherapy, to treat NSCLC after chemotherapy and radiation therapy. The goal of this trial is to learn if participants who receive calderasib and durvalumab live longer without the cancer growing or spreading compared to participants who receive placebo and durvalumab.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- The main inclusion criteria include but are not limited to the following:

- Has completed definitive platinum-based concurrent chemoradiotherapy (CCRT) prior to enrollment, without disease progression.
- Has provided a tumor tissue sample for central laboratory testing of Kirsten rat sarcoma G12C (KRAS G12C) status, programmed cell death ligand 1 (PD-L1) status, and biomarker research.
- Tumor tissue sample has a demonstrated presence of KRAS G12C mutation and an evaluable PD-L1 status result.
- If human immunodeficiency virus (HIV)-infected, has well-controlled HIV on antiretroviral therapy (ART).
- If hepatitis B surface antigen (HBsAg)-positive, has undetectable hepatitis B virus (HBV) viral load and has received HBV antiviral therapy.
- If has a history of hepatitis C virus (HCV) infection, has undetectable HCV viral load.
- Has a body weight ≥35 kg.
Exclusion criteria
- The main exclusion criteria include but are not limited to the following:
- Has a diagnosis of small cell lung cancer or mixed tumors with small cell elements.
- Has a gastrointestinal disorder affecting absorption or is unable to swallow orally administered medication.

- Has uncontrolled, significant cardiovascular disease or cerebrovascular disease.
- Is HIV-infected with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease.
- Has received prior treatment (other than definitive CCRT) for NSCLC.
- Has a known additional malignancy that is progressing or has required active treatment within the past 3 years.
- Has an active autoimmune disease that has required systemic treatment in the past 2 years.
- Has a history of, or has current, (noninfectious) pneumonitis/interstitial lung disease that required/requires steroids.
- Has an active infection requiring systemic therapy.
- Has a history of stem cell/solid organ transplant.
- Has not adequately recovered from major surgery or has ongoing surgical complications.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
