Delstudie 01I: En studie av utredningsmedel hos deltagare med tidigare behandlade stadium IV skivepitelcancer, icke-småcellig lungcancer (NSCLC) (MK-3475-01I/KEYMAKER-U01I)

10 november 2026 uppdaterad av: Merck Sharp & Dohme LLC

KEYMAKER-U01 Delstudie 01I: En fas 2, randomiserad, paraplystudie med rullande armar av utredningsagenter hos deltagare med tidigare behandlad stadium IV skivepitelcancer icke-småcellig lungcancer (NSCLC)

Researchers are looking for other ways to treat metastatic squamous non-small cell lung cancer (NSCLC). Squamous NSCLC is cancer that starts in squamous cells, which are flat cells that line the inside of the airways in the lungs. Metastatic means the cancer has spread to other parts of the body.

Standard treatment (usual treatment) for metastatic squamous NSCLC is immunotherapy with or without chemotherapy. Immunotherapy is a treatment that helps the immune system fight cancer. Chemotherapy is medicine that destroys cancer cells or stops them from growing. However, standard treatment may not work or may stop working to treat metastatic squamous NSCLC.

Researchers want to learn if study treatments that are antibody drug conjugates (ADCs) can treat metastatic squamous NSCLC that did not respond (get smaller or go away) to standard treatment. An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells.

The main goals of this study are to learn about:

  • The cancer response to the study treatments compared to chemotherapy
  • The safety of the study treatments and if people tolerate them

This study is one of the substudies being conducted under one pembrolizumab umbrella master protocol (MK-3475-U01/KEYMAKER-U01).

Åtgärdsbeskrivning
Tidsram
Objective Response Rate (ORR)
Tidsram: Up to approximately 81 months

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) as assessed per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). ORR will be assessed by Blinded Independent Central Review (BICR). The percentage of participants who experience CR or PR as assessed by the investigator will be presented.

Up to approximately 81 months
Number of participants who experience one or more adverse events (AEs)
Tidsram: Up to approximately 81 months

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 who experience an AE will be reported.

Up to approximately 81 months
Number of participants who discontinue study intervention due to an AE

Duration of Response (DOR)
Tidsram: Up to approximately 81 months

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 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.

Up to approximately 81 months
Progression-free Survival (PFS)
Tidsram: Up to approximately 81 months

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.

Up to approximately 81 months
Overall Survival (OS)
Tidsram: Up to approximately 81 months

OS is defined as time from randomization to death due to any cause.

Up to approximately 81 months
