Mr. Thiele, could you give us a brief introduction to the concept of Real-World Evidence (RWE) and explain why it is becoming particularly important in modern medicine?
Real-World Evidence (RWE) is based on the analysis of real-world data (RWD), such as electronic health records (EHR), medical claims, and wearable-generated data, to generate clinical evidence. By providing a broader, more diverse, and realistic view of treatment efficacy and safety in real-world settings, RWE studies complement findings from randomized controlled trials. They help assess long-term effects and support cost-benefit analyses, which are essential for healthcare decision-makers. RWE also reveals variations in treatment effects across different patient populations. Regulatory agencies like the FDA and EMA increasingly recognize the value of RWE for regulatory decision-making, accelerating drug approvals and the expansion of indications for existing treatments.

With the help of CGM and Alcedis, AstraZeneca conducted the InspeCKD study, in which anonymized health data from the CGM research panel docmetric was examined. What were the findings?
In Germany, chronic kidney disease (CKD) is often diagnosed at an advanced stage. Patients with high blood pressure, diabetes mellitus, and/or cardiovascular disease are at higher risk and should undergo regular screening as per clinical guidelines. The InspeCKD study analyzed anonymized electronic patient health records from these risk groups within German general practices. The results of this real-world study highlight gaps in laboratory diagnostic care for high-risk patients and emphasize the need for better adherence to guideline recommendations in primary care to enhance early detection and treatment of CKD.
In your opinion, which regulations and technological innovations are crucial for optimizing the collection and analysis of RWE data?
Standardized data formats and protocols are necessary to integrate and analyze real-world data from diverse sources. Cloud-based platforms enable the secure storage and processing of large-scale clinical and health information. To ensure data quality and compliance, binding regulatory frameworks are essential. Both the FDA and EMA have issued guidelines to establish clear methodologies for collecting, analyzing, and interpreting RWE data. Artificial Intelligence (AI) and Machine Learning (ML) play a critical role in identifying patterns within large datasets, improving drug safety, and advancing personalized medicine. Natural language processing (NLP) can be particularly valuable for extracting insights from unstructured clinical text, such as medical reports and patient records. Additionally, blockchain technology provides a transparent and secure method for verifying and managing healthcare data, ensuring data integrity and privacy.
What are the biggest challenges in integrating RWE into clinical practice, especially in terms of data quality and privacy?
RWE data comes from various sources, including electronic health records, insurance claims, patient registries, and wearables, all of which use different formats and terminologies. This lack of standardization makes data integration and comparability challenging. Additionally, real-world data can be incomplete, inaccurate, or biased, necessitating thorough data validation and transformation. From a privacy perspective, safeguarding patient information is critical. The collection, storage, and analysis of RWE data must comply with strict regulatory privacy laws. All data must be anonymized to protect patient identities, and clear communication is essential to maintain transparency and trust. Patients should be fully informed about how their medical data is used to encourage participation and engagement in RWE studies.
What future developments and trends do you see in the use of RWE to improve healthcare?
Several promising trends will shape the future of real-world evidence in healthcare. The integration of AI and ML will refine the analysis of RWE data, leading to more precise clinical insights and personalized treatment strategies. Wearables and mobile health devices will play an increasingly significant role in continuously collecting real-time patient health data, enabling proactive disease monitoring and early interventions. Furthermore, interoperability between different healthcare systems and data sources will improve through standardized formats and APIs, creating more comprehensive and reliable datasets. Patient-centric approaches will enhance patient engagement in clinical research and real-world studies, fostering trust and increasing the availability of high-quality RWE. Regulatory agencies will continue incorporating RWE in decision-making processes, potentially expediting drug approvals and broadening treatment options. Finally, blockchain technology will further enhance data security, transparency, and compliance with regulatory standards. These advancements will collectively elevate the quality, efficiency, and impact of real-world research in healthcare.
