About the MARVL-US Study
The MARVL-US Study is designed to unlock a clearer understanding of how HYMPAVZI™ (marstacimab-hncq) impacts the health and daily life of individuals living with hemophilia in real-world settings and routine care, beyond the clinical trial experience through de-identified medical record collection and surveys. Sign up takes 10 minutes or less. Once enrolled, you will be asked to complete up to 6 paid surveys online for the first year. PicnicHealth will take care of the rest.
By allowing PicnicHealth to collect, digitize and de-identify (removal of personal details) your or your child’s medical records, you have the opportunity to participate in hemophilia research while staying in control of your health data.
The study team will use your records and survey responses to better understand how HYMPAVZI™ (marstacimab-hncq) impacts your hemophilia in real-world settings.

MARVL-US combines and analyzes medical records
As part of this non-interventional study (research that observes your health without asking you to try new treatments), the MARVL-US research team may analyze you or your child's de-identified data and survey responses alongside other participants' to better understand real-world HYMPAVZI™ (marstacimab-hncq) use and how hemophilia affects daily life.
To protect your privacy, your name and personal details are removed through de-identification, ensuring researchers receive only essential health information. By combining data from many participants, the study can identify patterns and insights that may not be visible to any single healthcare provider.

Records are yours to keep
We’ll continue to collect new records for the duration of the study. Any records collected are yours to keep forever, to use and share as you please.
