CARE Initiative: Real-world Emulation of the KEYNOTE-189 Trial [DS4]
- Conditions
- Metastatic Non Small Cell Lung Cancer
- Interventions
- Registration Number
- NCT06585189
- Lead Sponsor
- Aetion, Inc.
- Brief Summary
The goal of this non-interventional study is to emulate the KEYNOTE-189 randomized controlled trial of pembrolizumab for the treatment of metastatic non-small cell lung cancer using real-world, electronic health record data. The main questions this study aims to answer are:
1. Do patients with metastatic non-small cell lung cancer (NSCLC) treated with pemetrexed, cisplatin/carboplatin, and pembrolizumab have improved real-world overall survival (rwOS) and real-world progression-free survival (rwPFS) compared with patients treated with pemetrexed and cisplatin/carboplatin alone?
2. How do the results of this non-interventional study compare to those of the KEYNOTE-189 randomized controlled trial?
- Detailed Description
The Coalition to Advance Real-World Evidence through Randomized Controlled Trial Emulation (CARE) Initiative is a program designed to build an empirical evidence base for the use of real-world data (RWD) in clinical and regulatory decision-making. Using randomized controlled trials (RCTs) as a benchmark for causal effect estimates, a series of RCT emulations will be conducted across varying trials, real world data sources, and study design elements to better understand under what conditions non-interventional studies, using data generated during routine clinical care, can provide reliable conclusions about drug effectiveness.
In this study, real-world electronic health record (EHR) data will be used to emulate the KEYNOTE-189 efficacy trial of pembrolizumab as first-line therapy in patients with metastatic non-small cell lung cancer (NSCLC) without epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) sensitizing mutations. Similarly to the KEYNOTE-189 trial, this study will compare real-world overall survival (rwOS) and real-world progression-free survival (rwPFS) between patients who initiate pemetrexed, platinum-based chemotherapy, and pembrolizumab, and patients who initiate pemetrexed and platinum-based chemotherapy alone.
