A Study of Investigational Agents in Participants With Previously Treated Stage IV Nonsquamous Non-small Cell Lung Cancer (NSCLC) (MK-3475-01H/KEYMAKER-U01)

Phase 2
Recruiting
Conditions
Carcinoma, Non-Small-Cell Lung
Interventions
Registration Number
NCT06780085
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

Researchers are looking for new ways to treat metastatic nonsquamous non-small cell lung cancer (NSCLC) that has been treated before. Metastatic means the cancer has spread to other parts of the body. Nonsquamous means the cancer did not start in squamous cells, which are flat cells that line the inside of the lungs.

Standard treatment (usual treatment) for NSCLC is surgery, then immunotherapy with or without chemotherapy after surgery. Immunotherapy is a treatment that helps the immune system fight cancer. Chemotherapy is a medicine that works to destroy cancer cells or stop them from growing.

However, standard treatment may not work or may stop working for some people. Researchers want to know if 2 antibody drug conjugates (ADCs) can help treat metastatic nonsquamous NSCLC that did not respond (get smaller or go away) to treatment. An ADC attaches to specific targets on cancers cells and delivers treatment to destroy those cells.

Researchers will compare 2 different ADCs (the study treatments) to chemotherapy in this study. The goals of this study are to learn:

* About the safety of the study treatments and if people tolerate them

* How many people have the cancer respond to the study treatments

Detailed Description

The master screening protocol is MK-3475-U01 (KEYMAKER-U01) - NCT04165798

  • Human Immunodeficiency Virus (HIV)-infected participants must have well controlled HIV on antiretroviral therapy (ART)
  • Participants who are hepatitis B surface antigen (HBsAg) positive have received hepatitis B virus (HBV) antiviral therapy for at least 4 weeks and have undetectable HBV viral load prior to randomization
  • Participants with history of hepatitis C virus (HCV) infection are eligible if HCV viral load is undetectable at screening

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)Up to approximately 60 months

ORR is defined as the percentage of participants with Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1). The percentage of participants who experience CR or PR as assessed by Blinded Independent Central Review (BICR) will be presented.

Percentage of Participants with at Least One Adverse Event (AE)Up to approximately 25 months

An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. The percentage of participants who experience an AE will be reported.

Percentage of Participants Who Discontinued Medication Due to an AEUp to approximately 24 months

An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. The percentage of participants who discontinue study intervention due to an AE will be reported.

Secondary Outcome Measures
NameTimeMethod
Duration of Response (DOR)Up to approximately 60 months

For participants who demonstrate a confirmed CR (disappearance of all target lesions) or (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 progressive disease (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 millimeters (mm). The appearance of one or more new lesions is also considered PD. DOR as assessed by BICR will be presented.

Progression-free Survival (PFS)Up to approximately 60 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.

Overall Survival (OS)Up to approximately 84 months

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