A Phase 3 interventional study of Calderasib and Durvalumab in Non-small Cell Lung Cancer, sponsored by Merck Sharp & Dohme LLC. Recruiting at 115 sites in 18 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-10.

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.

The main exclusion criteria include but are not limited to the following:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.
PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Change From Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) Global Health Status (GHS)/Quality of Life (QoL) (Items 29 & 30) Combined Score
EORTC QLQ-C30 is a questionnaire to assess the overall quality of life (QoL) of cancer patients. Participant responses to questions regarding Global Health Status (GHS; "How would you rate your overall health during the past week?") and QoL ("How would you rate your overall quality of life during the past week?") are scored on a 7-point scale (1= Very poor to 7=Excellent). The combined score of GHS (Item 29) and QoL (Item 30) is computed by averaging the raw scores of the 2 items and then applying a linear transformation to standardize the average score, so that the combined scores range from 0-100. A higher score indicates a better outcome. The change from baseline in GHS and QoL combined score will be presented.
Time frame: Baseline and up to approximately 9 years
Change From Baseline in Physical Functioning (EORTC QLQ-C30 Items 1-5) Combined Score
EORTC QLQ-C30 is a questionnaire to assess the overall QoL of cancer patients. Participant responses to 5 questions about their physical functioning (Items 1 to 5) are scored on a 4-point scale (1=Not at All to 4=Very Much). The combined score of items 1 to 5 was computed by averaging the raw scores of the 5 items and then applying a linear transformation to standardize the average score, so that the combined scores range from 0-100. A higher score indicates a better outcome. The change from baseline in EORTC QLQ-C30 physical functioning (Items 1-5) combined score will be presented.
Time frame: Baseline and up to approximately 9 years
Change from Baseline in Role Functioning (EORTC QLQ-C30 Items 6 & 7) Combined Score
The EORTC QLQ-C30 is a cancer specific health-related quality of life questionnaire. The role functioning score is based on participant responses to questions scored on a 4-point scale (1=Not at All to 4=Very Much). The combined score was computed by averaging the raw scores of Items 6 and 7 and then applying a linear transformation to standardize the average score, so that the combined scores range from 0-100. Higher scores indicate better role functioning. The change from baseline in EORTC QLQ-C30 Role Functioning (Items 6 and 7) combined score will be reported.
Time frame: Baseline and up to approximately 9 years

Started Jun 2026 (actual). Primary completion is estimated for Dec 2032, 77 months after the start.
Of 314 industry-sponsored phase 3 interventional studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 39 months of starting (the median), counting those still running; a quarter within 27 and three quarters within 57. This study's planned 77 months is above that.
Counting every sponsor, half of 423 studies reached it within 45 months; a quarter within 30 and three quarters within 69.
