Deelonderzoek 01I: Een onderzoek naar onderzoeksagentia bij deelnemers met eerder behandeld stadium IV plaveiselcel-niet-kleincellige longkanker (NSCLC) (MK-3475-01I/KEYMAKER-U01I)

KEYMAKER-U01 Substudie 01I: een fase 2, gerandomiseerde, overkoepelende studie met rollende armen van onderzoeksagenten bij deelnemers met eerder behandeld stadium IV plaveiselcellongkanker (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).

Tijdsspanne
Objective Response Rate (ORR)
Tijdsspanne: 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).

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)
Tijdsspanne: 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)
Tijdsspanne: Up to approximately 81 months

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

Up to approximately 81 months
