Run by University of Edinburgh · NCT07240883 · Data updated 2026-11-12
This project will collect symptom reports, medical information, and biological samples from people in the UK with diagnosed endometriosis to try to find patterns that speed diagnosis and improve care.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are UK residents aged 16 or older with a clinical diagnosis of endometriosis in the past 10 years who can use the ENDO1000 mobile app or web equivalent and are willing to provide samples and symptom data.
✕Probably not a fit
People who are pregnant, have known severe coagulation disorders, or active Hepatitis B/C or HIV (and those without a clinical diagnosis or who live outside the UK or cannot use the app) will not be eligible and thus are unlikely to benefit from participation.

What this trial studies
ENDO1000 is a UK-wide, longitudinal observational project that combines mobile app or web-based symptom tracking with clinical records and biosample collection to create a large, multimodal dataset. Participants aged 16 and over with a clinical diagnosis of endometriosis within the past 10 years are invited to report symptoms and provide samples remotely where possible. The project excludes pregnant people and those with certain infections or severe coagulation disorders because of sample-postage and safety rules. Collected data aim to support data-driven research on diagnosis, pain management, and personalized treatment pathways over time.
Why it matters
Potential benefit: If successful, the project could help shorten the diagnostic delay and enable more personalised pain management for people with endometriosis.
How similar studies have gone: Prior observational cohorts and app-based symptom-tracking projects in endometriosis and other conditions have produced useful insights, but large UK-wide efforts combining longitudinal app data, clinical records, and biosamples remain relatively novel.
