A Phase 3 interventional study of Calderasib and Pembrolizumab (+) Berahyaluronidase alfa in Non-small Cell Lung Cancer, sponsored by Merck Sharp & Dohme LLC. Recruiting at 225 sites in 30 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-10.

Researchers want to learn if the study medicines calderasib and subcutaneous (SC) pembrolizumab can be used to treat non-small cell lung cancer (NSCLC) when given together. Calderasib is a targeted therapy for the KRAS G12C mutation.
The goal of this study is to learn if people who receive calderasib with SC pembrolizumab live longer without the cancer growing or spreading than in people who receive SC pembrolizumab with chemotherapy.

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.
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.
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.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
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 Global Health Status/Quality of Life (GHS/QoL) (Items 29, 30) on the European Organization for Research and Treatment of Cancer QoL Questionnaire-Core 30 (EORTC QLQ-C30)
The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to the questions "How would you rate your overall health during the past week?" and "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). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in the score of EORTC QLQ-C30 Items 29 and 30 will be presented. Higher scores indicate a better overall health status.
Time frame: Baseline and up to approximately 81 months
Change from Baseline in Dyspnea Score (Item 8) on the EORTC QLQ-C30
The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant response to the question "Were you short of breath?" is scored on a 4-point scale (1=Not at All to 4=Very Much). The change from baseline in the score of EORTC QLQ-C30 Item 8 will be presented. A higher score indicates a worse level of dyspnea.
Time frame: Baseline and up to approximately 81 months

Participant response to the question "Have you coughed?" is scored on a 4-point scale (1=Not at All to 4=Very Much). The change from baseline in the score of EORTC QLQ-C13 Item 31 will be presented. A higher score indicates more frequent coughing.
Time frame: Baseline and up to approximately 81 months
Change from Baseline in Chest Pain Score (Item 40) on the EORTC QLQ-LC13
The EORTC QLQ-C13 is lung cancer-specific supplemental questionnaire used in combination with the EORTC QLQ-C30. Participant response to the question "Have you had pain in your chest?" is scored on a 4-point scale (1=Not at All to 4=Very Much). The change from baseline in the score of EORTC QLQ-C13 Item 40 will be presented. A higher score indicates a worse level of chest pain.
Time frame: Baseline and up to approximately 81 months
Time to Deterioration (TTD) in GHS/QoL (Items 29, 30) on the EORTC QLQ-C30
TTD is defined as the time from baseline to the first onset of a ≥10-point negative change (decrease) from baseline in global health status (GHS) and quality of life (QoL) (EORTC QLQ-C30 Items 29 and 30) score. Participant responses to the questions "How would you rate your overall health during the past week?" and "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). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The TTD, as assessed based on a ≥10 point negative change (decrease) from baseline in GHS and QoL, will be presented. A longer TTD indicates a better outcome.
Time frame: Baseline and up to approximately 81 months

The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant response to the question "Were you short of breath?" is scored on a 4-point scale (1=Not at All to 4=Very Much).
