Shape the future of PNH research
When you contribute your medical records to the PNH research, you join thousands of other patients who have participated in research and empowered their communities through PicnicHealth.
You may be eligible for this study if:
- You have a confirmed PNH diagnosis
- You intend to initiate danicopan treatment as an add-on to ravulizumab or eculizumab
- You are aged 18 or older and receive medical care in the US

What is PLEDGE?
PLEDGE is an observational research effort, meaning no additional appointments, lab work, or tests are required. You can participate entirely from the comfort of your home.

By allowing PicnicHealth to collect and digitize your medical records, you can participate in PNH research while staying in control of your health data.
The Alexion Study team will analyze your medical records as part of this research effort to gather insights into the day-to-day lives of individuals and families taking danicopan to treat PNH.

We combine and analyze medical records
As part of this observational study, the PLEDGE team may analyze your medical records alongside those of other study participants to gain a clearer picture of how PNH affects daily life. By combining data from many participants, the study can identify patterns and insights that may not be visible to any single physician. To protect your privacy, all personal details that could identify you are removed through a process called de-identification, ensuring that researchers receive only the essential health information they need.

Records are yours to keep
We’ll stop collecting new records, but any records collected are yours to keep forever to use and share as you please.
