Not just a study.
Contribute to research, gain insight about your health.

As someone living with PNH, you may have a lot to manage. We collaborated with other Folia users who have PNH to make sure data you track in the app is not only useful for research, but also for you!

Over the course of the study, you’ll be building a personal health record in the Folia app, where you’ll be able to leverage your data to see trends in how you’re feeling and assess how your treatments may be working for you.

Plus, you can also expect:

  • A dedicated team of user support specialists who will host events to better learn how to design the app to better suit your needs

  • Tailored tips on how to leverage your PNH observations tracked in the Folia app to bring to your clinic appointments

  • Personalized reports and graphs to visualize your data

  • Community newsletters and virtual sessions to learn how others are navigating their PNH

  • At the end of the study, you will get a community insights report of what other participants with PNH tracked too!
