What Is Real World Data in Clinical Trials?
Real World Data (RWD) refers to health-related information collected outside controlled clinical trials, such as from electronic health records (EHRs), insurance claims, patient registries, wearable devices, and patient-reported outcomes.
Real World Evidence (RWE) vs Traditional Clinical Trial Data
RWE is the meaningful evidence derived from analyzing RWD—showing how interventions perform in everyday settings—unlike randomized controlled trials (RCTs), which focus on “can the drug work?” versus RWE asking “does the drug work?”
Regulatory Agencies’ Growing Emphasis on RWD
Regulators are placing increasing importance on the role of real world data and real world evidence in decision-making. The FDA has formally defined both RWD and RWE and continues to issue guidance frameworks.
This growing emphasis highlights the value of RWD in complementing traditional trial data and supporting faster, evidence-based approvals.
Why Use Real World Data in Clinical Trials?
Enhancing External Validity and Patient-Centricity
RCTs often lack representation of diverse populations. RWD fills that gap, making trial findings more generalizable and supporting patient-centric healthcare by reflecting real treatment contexts.
Supporting Post-Marketing Surveillance and Label Expansion
RWE is increasingly used post-approval to monitor long-term safety, inform label changes, and support reimbursement or regulatory submissions.
Improving Diversity and Representativeness in Clinical Outcomes
Data from broad patient groups—including underserved and comorbid populations—allows sponsors to understand treatment effectiveness and tailor interventions, improving outcomes that matter in real-world settings.
How CROs Are Integrating Real World Data in Clinical Trials
Designing Hybrid Trials That Combine RCT and RWD
By designing hybrid trials that blend real-world data as external comparators, especially for rare diseases or when randomized controls are impractical.
Data Collection Tools and Real World Data Platforms
Modern CROs leverage advanced platforms capable of handling diverse RWD sources, to enable scalable, secure, and compliant data capture.
CRO Strategies for Regulatory-Grade RWD Collection
Specialized CROs develop rigorous processes for RWD cleaning, mapping, and analysis to ensure it meets regulatory standards, often offering Biometric and RWE-specific services.
Challenges in Using Real World Data in Clinical Trials
Data Privacy, Ethics, and Informed Consent
Since RWD often originates from routine care, CROs must navigate data privacy regulations and ensure ethical use with transparent informed consent processes.
Ensuring Data Quality, Standardization, and Interoperability
RWD can suffer from missing entries or inconsistent formats. Standardizing diverse data streams from claims, EHRs, and registries remains a significant hurdle.
Balancing Real World Complexity with Clinical Rigor
RWD’s variability can introduce bias. CROs must design studies that preserve scientific rigor, using statistical methods and endpoints to translate messy real-life data into reliable evidence.
The CRO Advantage in Managing Real World Data
Analytics and Data Science Capabilities
CROs enhance patient-centric healthcare through analytics teams that transform RWD into actionable insights and support precision study designs.
Experience with Regulatory Submissions Involving RWE
With growing CRO expertise in RWE, sponsors benefit from partners experienced in navigating regulatory expectations and crafting submission-ready evidence packages.
Real World Data in Clinical Trials: Use Cases and Case Studies
Enhancing Trial Design with Real-World Insights
RWD helps fine-tune protocol design, inclusion/exclusion criteria, and endpoint selection, boosting feasibility and recruitment efficiency..
Supporting Rare Disease and Longitudinal Studies
In rare or long-term contexts, RWD serves as historical control data or natural history documentation, enabling trials that would otherwise be unfeasible.
Enabling Pragmatic Trials and Digital Health Integration
CROs are facilitating pragmatic designs that reflect real-world delivery and integrating digital tools—like wearables and EHR-linked platforms—to enhance data richness and patient engagement.
Future Outlook: The Expanding Role of Real World Data in Clinical Trials
AI and Machine Learning to Analyze RWD at Scale
With AI-powered analytics, CROs can process massive RWD sets, detect patterns, and improve endpoint identification.
Decentralized Clinical Trials and RWD Synergy
The rising trend of decentralized trials pairs naturally with RWD—further supporting patient-centric healthcare by enabling flexible, remote data capture and participation.
