Overview
Traditional clinical trials are the primary way new cancer treatments are tested, but they often exclude many types of patients seen in everyday practice, making it difficult to know how a drug will perform in the "real world." This research introduces the ENCORE (Emulating Comparative Oncology Trials with Real-world Evidence) framework, a standardized methodology designed to help researchers use real-world data (RWD) from electronic health records to replicate the findings of clinical trials.
Using data from the Flatiron Health Research Database, the team outlined a rigorous process for selecting patient groups, ensuring data quality, and applying advanced statistical methods. This framework addresses common challenges in real-world research, such as how to account for differences in patient health and treatment history that aren't present in a strictly controlled trial environment.
Why this matters
This research is a significant step toward making real-world evidence a standard part of how new treatments are evaluated and approved. By providing a clear, reliable roadmap for trial emulation, the ENCORE framework helps ensure that evidence generated from routine clinical care is robust enough for use by regulators, such as the FDA, and healthcare providers. Ultimately, this approach has the potential to accelerate patient access to life-saving therapies and provide a more complete picture of how treatments work for a broader, more diverse population of patients.
