NCT ID NCT07240883
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
ENDO1000 is a UK-wide research project involving 1000 people with endometriosis. Participants will use a mobile app to track symptoms like pain, fatigue, and sleep, and some will provide blood, urine, and other samples at home. The goal is to collect detailed data over time to help researchers find better ways to diagnose and treat endometriosis, a condition affecting 1 in 10 women.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better ways to diagnose endometriosis earlier and more personalized treatments based on individual symptoms and biology.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly help participants. Results may take years to translate into clinical practice.
