While the definition of real world evidence (RWE) is still evolving, most proponents associate it with data that is derived from medical practice among heterogeneous sets of patients in the real world setting. It is the integration of data gathered from various sources, such as EHRs, medical charts, patient claims and billing activities, product and disease registries. The data collected from the aforementioned sources has proven to be a potential alternative and complement to traditional RCTs. It holds out the promise of reducing time and costs of product approvals, identifying new uses for existing products, increasing our ability to treat rare diseases, and improving clinical practices for using drugs and medical devices.

RWE has the potential to support aspects of drug development and commercialization. It can expedite the generation of hypotheses, enable identification of sub-populations with higher risk-benefit ratios to target development efforts, support more efficient and targeted patient recruitment, reduce the burden of data collection and reporting, and lead to earlier conclusions about effectiveness and faster decisions about value and reimbursement. RWE makes possible a new paradigm for closely monitoring the safety and efficacy of drugs prior to and after their approval. This close-monitoring during clinical trials, post-approval commitment phase, or after approval of a subset of patients (through a combination of personal monitoring devices, smartphone apps, phone calls and virtual visits) are likely to benefit patients, researchers and regulators. It is anticipated that the US FDA, European Medicines Agency (EMA) and other regulatory authorities are likely to increase the utilization of real world evidence in influencing the regulatory decisions associated with the safety and efficacy of medical products.

Real World Data Sources

As per Roots Analysis, there are almost a dozen different sources of data which can influence the REAL WORLD EVIDENCE market.

Potential Applications of RWE

RWE has enormous potential to contribute towards healthcare decision-making, in terms of pre-approval and post-approval guidelines. It can significantly decrease the time and cost of drug development, and can aid in the early stage research in order to discover new innovative treatments. Further, it eliminates the necessity of recruiting clinical subjects to analyze the safety factors of a treatment. If the data generated through RWE is of sufficiently high quality, then it can certainly influence the clinical decision-making processes of the regulatory authorities.

Growth Drivers and Challenges in the RWE Market

Over the years, industry stakeholders are increasingly utilizing RWE in order to reduce costs and optimize operations of their product lifecycle. The numerous potential applications of real world evidence in establishing patient safety standards, ensuring effectiveness of a product and treatment paths, productive market assessment and the disease patterns have further augmented its necessity. Although RWE studies have numerous opportunities in the healthcare sector, there are several associated challenges, which act as road blocks to their future growth. The major road block for optimum utilization of RWE data is the availability of data in complex or scattered form that has to be structured in order to derive meaningful insights from it.
