Precision Medicine: Way Forward through Real World Data

Precision Medicine Way Forward through Real World Data

By Anita Mangtani, Sr. Healthcare Consultant, Life Sciences & Rajat Shukla, Sr. Healthcare Consultant, Life Sciences

Precision medicine, also known as personalized medicine, is a rapidly advancing field that seeks to tailor medical treatments to individual patients based on their unique genetic, environmental, and lifestyle factors. The use of real-world data (RWD)  is a key driver of precision medicine and has the potential to revolutionize healthcare by providing a more comprehensive understanding of how treatments perform in the real world and enabling the development of more targeted, personalized treatments.

Benefits of RWD

One of the primary advantages of using RWD in precision medicine is that it allows researchers and clinicians to gain a better understanding of how patients respond to treatments in the real world. Clinical trials, which have traditionally been the gold standard for evaluating the safety and efficacy of new treatments, have several limitations, including small sample sizes, strict eligibility criteria, and limited follow-up periods. In contrast, RWD enables researchers to analyze data from large, diverse patient populations over extended periods of time, providing a more comprehensive view of how treatments perform in the real world.

RWD can also be used to identify patient subgroups that are likely to respond better to specific treatments. By analyzing large datasets, researchers can identify genetic, environmental, and lifestyle factors that influence how patients respond to treatments. This information can then be used to develop more targeted treatments that are tailored to the specific needs of individual patients. This approach is particularly useful in complex diseases like cancer, where different patients may respond differently to the same treatment.

Another advantage of RWD is that it can be used to monitor the safety of treatments in the real world. Adverse events that are rare or occur only in specific patient subgroups may not be identified during clinical trials but can be detected through analysis of RWD. This information can be used to improve patient safety by identifying potential safety concerns early on and implementing appropriate interventions.

Challenges Accompanying RWD

Despite the above-mentioned benefits, the use of RWD in precision medicine also presents a few challenges. One of the biggest challenges is ensuring the quality and reliability of the data. RWD is often collected from a variety of sources and may be incomplete or inconsistent. In addition, there are concerns about patient privacy and data security, as RWD often contains sensitive information that must be protected.

To address these challenges, it is essential to establish robust data quality control and governance measures. This involves ensuring that data is collected consistently and accurately while appropriate measures are in place to protect patient privacy and data security. Additionally, it is important to ensure that RWD is analyzed in a way that is sensitive to the needs of diverse patient populations to avoid perpetuating health disparities.

Despite these challenges, the use of RWD in precision medicine has already yielded significant benefits. For example, the Cancer Genome Atlas (TCGA) project, which used RWD to analyze the genomes of over 11,000 cancer patients, identified molecular subtypes of cancer that respond differently to treatment. This has led to the development of more targeted, personalized treatments for different subtypes of cancer, resulting in improved patient outcomes.

Another notable example is the use of RWD in the development of vaccines for COVID-19. The clinical trials that were conducted to evaluate the safety and efficacy of the vaccines involved a relatively small number of participants and had limited follow-up periods. However, the real-world data collected after the vaccines were approved for emergency use has provided valuable insights into their safety and effectiveness in diverse patient populations.

The use of RWD in precision medicine has the potential to revolutionize healthcare by providing a more comprehensive understanding of how treatments perform in the real world and enabling the development of more targeted, personalized treatments. However, it is important to address the challenges and limitations associated with the use of RWD, and to ensure that it is collected and analyzed in a way that is ethical, equitable, and respects patient privacy, with the right data quality control.
