Phase III, Open-label, First-line Study of Dato-DXd in Combination With Durvalumab and Carboplatin for Advanced NSCLC Without Actionable Genomic Alterations

Registration Number
NCT05687266
Lead Sponsor
AstraZeneca
Brief Summary

This is a Phase III, randomized, open-label, multicenter, global study to compare the efficacy and safety of Datopotamab Deruxtecan (Dato-DXd) in combination with durvalumab and carboplatin compared with pembrolizumab in combination with histology-specific platinum-based chemotherapy as first-line treatment of adults with stage IIIB, IIIC, or IV NSCLC without actionable genomic alterations (including sensitizing EGFR mutations, and ALK and ROS1 rearrangements).

Detailed Description

Participants with locally advanced or metastatic NSCLC without actionable tumor tissue genomic alterations and confirmed to meet all eligibility criteria will be randomized in a 1:1 ratio to Dato-DXd in combination with durvalumab and carboplatin versus pembrolizumab in combination with histology-specific platinum-based chemotherapy as first-line treatment.

The primary objectives of the study are to demonstrate superiority of Dato-DXd in combination with durvalumab and carboplatin relative to pembrolizumab in combination with platinum-based chemotherapy by assessment of the following:

1. PFS by BICR in first-line treatment of participants with non-squamous TROP2 biomarker positive locally-advanced or metastatic NSCLC

2. OS in first-line treatment of participants with non-squamous TROP2 biomarker positive locally-advanced or metastatic NSCLC

3. PFS by BICR in first-line treatment of participants with non-squamous locally-advanced or metastatic NSCLC

4. OS in first-line treatment of participants with non-squamous locally-advanced or metastatic NSCLC

Primary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS) by blinded independent central review (BICR) in the non-squamous TROP2 biomarker positive populationApproximately 3 years

PFS is defined as time from randomisation until progression per Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST 1.1) as assessed by BICR, or death due to any cause.

Overall Survival (OS) in the non-squamous TROP2 biomarker positive populationApproximately 4 years

OS is defined as the time from randomisation until the date of death due to any cause.

PFS by BICR in the non-squamous populationApproximately 3 years

PFS is defined as time from randomisation until progression per RECIST 1.1 as assessed by BICR, or death due to any cause.

OS in the non-squamous populationApproximately 4 years

OS is defined as the time from randomisation until the date of death due to any cause.

Secondary Outcome Measures
NameTimeMethod
Clinical Outcome Assessments in ITT, non-squamous and TROP2 biomarker-defined populationsApproximately 4 years

Clinical Outcome Assessments, such as TTD in pulmonary symptoms (dyspnoea, cough and chest pain) as measured by the NSCLC-SAQ, and TTD in physical functioning as measured by PROMIS Physical Function short form 8c

PFS by investigator in ITT, non-squamous and TROP2 biomarker-defined populationsApproximately 3 years

PFS is defined as time from randomisation until progression per RECIST 1.1 as assessed by investigator clinical assessment, or death due to any cause.

PFS by BICR in ITT and TROP2 biomarker-defined populationsApproximately 3 years
