The Benefits of Digital Health for Rare Disease Research
How digital health could influence the conduct of rare disease studies and positively impact patient populations.

Digital health is at the forefront the clinical research industry as a potential game-changer. Mobile technology such as ResearchKit has the ability to significantly alter the conduct of clinical trials, including key operations like trial design, data collection and subject engagement.
While these applications will certainly affect all therapeutic areas, one notable part of the digital discussion is the potential benefit to rare disease research. The capabilities of mobile technology for rare disease studies could ease unique operational difficulties, improve study conduct and potentially increase quality of life for subjects.
Subject recruitment is among the many challenges rare disease studies present clinical researchers. While recruitment is a challenging task for many clinical trials, the difficulty is amplified for rare disease studies, as subjects are isolated to a small number of individuals. As such, clinical trial databases are limited and participants are difficult to locate, making it a struggle to meet enrollment goals. Digital health has the potential to reduce this struggle by significantly increasing communication reach. Platforms like ResearchKit amplify recruitment efforts to a global scale, increasing study awareness and potentially identifying a larger audience of eligible subjects.
Longitudinal studies provide insight into disease emergence and progression as well as the effects of long-term interventions. These types of studies are particularly important for rare disease research, as subject retention is vital to the continuation of a rare disease study due to the small patient populations. Longitudinal studies allow researchers to follow the same subjects throughout the course of their lifetime, reducing enrollment needs and accumulating valuable data over time.
Remote monitoring capabilities of some digital health tools could encourage an increase in longitudinal studies for rare diseases and assist during the data collection process. As treatments for rare diseases are limited, often patients must rely on solely investigational therapies throughout the course of a study. This limiting factor makes data accuracy even more significant. Remote monitoring objectifies study data by collecting real-time information from subjects using wearable technology and/or FDA-approved medical devices. Such capabilities also increase the patient-centricity of a clinical trial by reducing the amount of time a subject is required to visit a trial site—particularly important during a longitudinal study that could last decades.
Digital health also offers the opportunity for subjects to answer questions and submit data in real-time using applications like digital diaries or logs. This reduces the risk of recall bias and allows for more accurate data to be collected about subjects’ daily lives, providing insight into potential issues and patterns that would otherwise be unknown.
Rare disease subjects often live challenging lives, encountering adversity on a daily basis—physically and socially. Quality of life can be low and the idea that the subject is struggling alone can be emotionally taxing.
Digital health portals and forums reduce the feeling of isolation by promoting community and understanding. Using these outlets, subjects gather to freely communicate with peers and share factors that could affect their responses to certain drugs. Here, subjects learn more about their disease and are empowered by the ability to share their own data. A well-known online community, PatientsLikeMe, allows users to share health data and promote wellness. Due to the remote monitoring capabilities of wearable technology, mobile health users are able to provide in-depth information to these communities. Data sharing also helps pharmaceutical companies gain a better understanding of their subject population, making research more patient-centric and driving research most important to patients and their families.
While digital health is still in its infancy within the clinical research space, discussion on the improvement of trial design and the potential for rare disease subjects is very exciting.
