Rare Disease NewslettersEvery day can be delayed, postponed, or canceled when you or a loved one has a rare disease. We understand the unique challenges rare disease patients and trials face compared to those in more common indications. Lives are uprooted and postponed in search of treatment, and not just the lives of patients, but their entire care circles.
Our experience allows us to efficiently conduct rare disease studies by anticipating and mitigating risks while maintaining focus on the patient, the family, and their quality of life. We understand that every day without treatment means another day filled with doctor’s appointments, lab work, postponed opportunities, and canceled plans.

Her therapeutic expertise includes Ophthalmic indications from Anterior to Posterior Segment.
Why rare disease?
“Seeing the strength of the patients and families living with rare diseases continually inspires me to push for a better understanding of each patient’s disease and its impact on their lives. This enables more efficient and effective clinical trial development and, ultimately, can accelerate how fast we can bring meaningful therapies to patients who need it.”

Jana Benesh, PhD
Clinical Strategy Lead
Jana is a trained neuroscientist with a PhD in Neuroscience and Molecular Biology.

Read how we’re accelerating rare disease clinical development.Practical tools for sponsors, participants and champions of patient-centric trial development.
More than 90% of the 7,000 rare diseases known to science don’t have a single FDA approved treatment. There’s no time to waste in bringing meaningful treatments to lives affected by rare disease.
This toolkit was developed to support Sponsors, Patient Communities, and other stakeholders to operationalize true patient centricity in clinical development.
Leveraging advanced analytics to enhance patient recruitment.
Our medical informatics allow us to qualify and quantify rare disease patients and treating physicians through public and private data sources. We use industry-leading third-party data sources, as well as claims, pharmacy, specialty lab, and diagnostic data and electronic health records. We also examine the competitive landscape and investigator performance. This evidence-based methodology, combined with our core set of study-branded tools, helps sponsors to identify sites, and sites to identify potential patients.
With the right technology, we can reach patients where they are and, ultimately, speed the development of life-changing drugs for rare indications.
Scott Schliebner, Senior Vice President, Center for Rare Diseases
Advanced Therapies for Rare Disease Patient Communities
Currently, 95% of rare diseases have no FDA-approved treatments, and many treatments that do exist are burdensome for patients. Advanced Therapies hold some of the greatest promise for durable relief from rare disease. A greater understanding of disease mechanisms and the technologies of cell therapy, vectored gene therapy, and gene editing candidate treatments have prompted an increase in Advanced Therapy clinical trials for rare disease patient communities.
PRA understands the unique regulatory, scientific, and operational considerations that are necessary to carefully design these trials. To meet this need, we’ve established the Gene Therapy Working Group: a multidisciplinary team of dedicated professionals from the Center for Rare Diseases, Regulatory Affairs, Scientific Affairs, Study Start-Up, Patient Strategy, Real World Solutions, Mobile Health Platform, Medical Affairs, Clinical Pharmacology, and Clinical Delivery. This group provides guidance and support to all phases of Advanced Therapy clinical trials in the rare disease space, including, but not limited to:
- Assessment of appropriate technology-based solutions (ie, wearables, virtual study visits, etc.)
- Integration of evolving global regulatory landscapes
- Analysis of competitive landscapes
- Patient Journey and Patient Pathway analyses
- Training for research sites and operational teams
- Protocol refinements
Reducing the patient burden of participation.

We incorporate the patient perspective into all we do, because our work is first and foremost for the patient. We’ve built partnerships with relevant patient advocacy groups to create stronger study awareness and support, and we practice social listening and conduct patient-focused feasibility and focus groups to better understand what patients want. Our recruitment and retention strategies include the voice of patients and their caregivers during study design and throughout the entire product development lifecycle.
Watch how we’re engaging patients throughout our studies.We are rare together.
When you come to PRA with a rare disease treatment or clinical research study, you can expect to work with us. We believe clinical research happens at the person-to-person level. That’s why we want you to know who we are, so you can trust in our partnership.
Rare changes everything. Let’s change that, together.Learn more about PRA's Rare Diseases Advisory Committee
