- Conditions
- Metastatic Non Small Cell Lung Cancer
- Interventions
- Registration Number
- NCT05215340
- Lead Sponsor
- Daiichi Sankyo
- Brief Summary
This study is designed to assess the efficacy and safety of datopotamab deruxtecan (Dato-DXd) in combination with pembrolizumab versus pembrolizumab alone in participants with advanced or metastatic non-small cell lung cancer (NSCLC) of non-squamous histology.
- Detailed Description
The primary objective of the study is to compare the efficacy of Dato-DXd and pembrolizumab with pembrolizumab alone in terms of either Progression Free Survival (PFS) by BICR or Overall Survival (OS) for participants with advanced or metastatic NSCLC with non-squamous histology without actionable genomic alterations whose tumor has high programmed death-ligand 1 (PD-L1) expression (tumor proportion score; TPS ≥50%) and who have not previously received systemic therapy for advanced or metastatic NSCLC.
Eligible participants will be randomized in a 1:1 ratio to the control arm (pembrolizumab alone) or the experimental arm (Dato-DXd and pembrolizumab). The study will be divided into 4 periods: Tissue Screening Period, Screening Period, Treatment Period, and Follow-up Period.

Participants eligible for inclusion in the study must meet all inclusion criteria within 28 days of randomization into the study.
-
Sign and date the Tissue Screening and Main Informed Consent Forms, prior to the start of any study-specific qualification procedures.
-
Adults ≥18 years or the minimum legal adult age (whichever is greater) at the time of informed consent.
-
Histologically documented non-squamous NSCLC that meets all of the following criteria (Note: Subjects with squamous histology were eligible prior to Protocol Version 5.0. After Protocol Version 5.0, subjects with squamous histology are not eligible. Subjects with mixed histology, including those with a squamous component, remain eligible the study even after Protocol Version 5.0):
- Stage IIIB or IIIC disease and not candidates for surgical resection or definitive chemoradiation, or Stage IV NSCLC disease at the time of randomization (based on the American Joint Committee on Cancer, Eighth Edition). Participants with early-stage NSCLC who have relapsed should be restaged during screening to ensure their eligibility for the study.
- Documented negative test results for epidermal growth factor receptor (EGFR), lymphoma kinase (ALK), and proto-oncogene1 (ROS1) actionable genomic alterations (AGAs) based on analysis of tumor tissue. If test results for EGFR, ALK, and ROS1 are not available, subjects are required to undergo testing performed locally for these genomic alterations.
- No known AGAs in neurotrophic tyrosine receptor kinase (NTRK), proto-oncogene B-raf (BRAF), rearranged during transfection (RET), mesenchymal-epithelial transition factor (MET), or other actionable driver kinases with locally approved therapies. (Testing for genomic alterations besides EGFR, ALK, and ROS1 is not required prior to randomization). Subjects whose tumors harbor KRAS mutations are eligible for the study.
