How Real-World Evidence is Transforming Clinical Research
Created: 09.03.2024
How can the quality and safety of therapies in clinical research be sustainably improved? In the following blog article on Real-World Evidence (RWE), we highlight the transformative role of this valuable data. Find out how RWE supports decision making, influences regulatory frameworks and what hurdles exist in terms of data quality and privacy.
What is Real-World Evidence?
Real-world evidence refers to data collected outside of controlled clinical trials that provide important insights into patient care. Sources such as electronic health records, patient surveys and registries provide comprehensive insights into the efficacy and safety of therapies under real-world conditions. In contrast to clinical trials, which often study homogeneous patient groups, RWE reflects the diversity of the patient population and helps to optimize individual treatment approaches. The combination of different data sources improves the understanding of therapy outcomes and supports evidence-based decisions in healthcare.
Why is Real-World Evidence so important for clinical trials?
Real-World Evidence can ensure a more realistic assessment of the efficacy and safety of therapies in clinical trials. Combining controlled trial data with RWE optimizes the analysis of long-term effects and captures differences between patient groups, which in turn improves the validity of trial results and helps to identify potential safety risks at an early stage.
Regulatory authorities are increasingly recognizing the importance of real-world evidence for approval processes. New guidelines encourage the use of RWE to support regulatory submissions, which can accelerate market access for innovative therapies.

Cost efficiency and resource utilization with real-world evidence
By analyzing real-world data, companies can demonstrate the efficacy and safety of their treatments in a broader context. RWE also promotes personalized therapies by identifying patterns in patient care, which improves treatment quality and contributes to cost efficiency. As RWE is based on existing data sources such as electronic health records, it eliminates the need for time-consuming recruitment processes, speeding up the development process. At the same time, the continuous monitoring of therapy outcomes enables early identification of potential safety risks, which both increases patient safety and reduces costs in the long term.
Impact of RWE on market access
The integration of Real-World Evidence accelerates market access for new therapies as regulatory authorities increasingly recognize the value of this data in assessing efficacy and safety. RWE can support regulatory submissions and bring innovative treatments to market faster. It also enables targeted market development by analyzing different patient groups, allowing companies to strategically position their products.
Real-World Evidence: data quality and data integrity
One of the biggest challenges when using Real-World Evidence is ensuring data quality and integrity. Since RWE comes from different sources such as electronic health records, patient surveys and registries, inconsistencies can arise due to different documentation standards or collection methods. To address this, data validation and verification procedures are crucial. Another problem is the representativeness of the data. Certain patient groups, particularly those with chronic or rare diseases, may be underrepresented. Researchers need to develop strategies to close these gaps and reflect the diversity of the patient population.
Data protection and ethical aspects of real-world evidence
Handling sensitive patient data requires strict data protection measures and ethical considerations. When collecting and using RWE data, legal requirements such as the German General Data Protection Act (DSGVO) must be observed to ensure the protection of personal information. However, data protection can act as a barrier to the effective use of RWE. Companies need to develop processes that ensure data protection without compromising data quality or scope. Anonymized data sets or aggregated analyses can offer a solution here.
In addition, patients must be informed about the use of their data and understand its use in healthcare. Transparent communication promotes trust and increases willingness to participate. Companies should also fulfill technological requirements when implementing RWE in order to successfully integrate different data sources.
Real-World Evidence: Developments and technological possibilities
Advancing digitalization in healthcare is opening up new opportunities for collecting real-world evidence. Technologies such as artificial intelligence (AI) and machine learning enable efficient processing of large amounts of data and provide valuable insights that can revolutionize clinical research.
Through the use of electronic health records and mobile health applications, more comprehensive patient data can be collected in real time. AI algorithms in particular can recognize patterns and make more accurate predictions about therapy outcomes. In addition, wearables and mobile applications are becoming increasingly important as they provide continuous health data that helps to better understand the effectiveness of therapies under real-life conditions.
Integration of RWE into clinical processes
The integration of RWE into existing clinical processes is becoming increasingly important. The challenge is to seamlessly integrate RWE into all phases of drug development - from early research to market approval. Integration into clinical trials can increase the validity of results and better tailor products to patients' needs. A key aspect is the collaboration between different stakeholders such as researchers, clinics and regulatory authorities. The exchange of information enables the development of optimal approaches for the use of RWE. This requires a rethink in clinical research and a willingness to question traditional paradigms.
It is also important to train professionals in the collection and analysis of RWE data to ensure the necessary know-how. With the right technological tools and a clear focus on integration, the potential of RWE can be fully exploited despite some challenges.
Cooperation for the implementation of Real-World Evidence
A promising development is the establishment of partnerships between companies, research institutions and healthcare providers to fully realize the potential of RWE. Such collaborations promote the exchange of knowledge and resources, leading to innovative approaches to data use. In addition, joint projects can pool resources and integrate a broader diversity of perspectives into the research process. The focus should be on creating a culture of interdisciplinary working that enables faster adaptation to changing conditions in healthcare.
Through collaboration, challenges such as data integrity and representativeness can be specifically addressed, which in turn improves the application of real-world evidence in clinical trials. In the long term, this results not only in higher quality research results, but also in better patient care through targeted therapeutic approaches. Trust between the partners is crucial in order to break down barriers and create synergies that benefit everyone involved.
