What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study aims to understand how stem cells from menstrual blood and the immune system behave differently in women with endometriosis compared to healthy women. Researchers will collect menstrual blood, tissue samples, and questionnaires from 40 women aged 18-45. No treatments are tested; the goal is to find new targets for future diagnosis and therapy.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Our study population consists of 40 women aged between 18 and 45, 20 of whom have been diagnosed with endometriosis and 20 of whom are healthy volunteers. Participants will be recruited from the Department of Gynecology and Obstetrics at the Hospital Universitari Joan XXIII in Tarragona (Spain) during routine gynecological check-ups. Healthy volunteers will be selected through individual matching with participants in the study group, considering relevant demographic and clinical variables such as age and ethnic group. In addition, a sub-cohort of 10 women (5 per study group) will be selected from the main cohort to study in greater detail the intra-menstrual variations in the immunomodulatory properties of MenSCs. This sub-cohort will include participants who agree to provide menstrual blood samples from days 1 to 5 (both inclusive) to analyze dynamic changes in the cells obtained, while maintaining the same general inclusion and exclusion criteria as in the main study.
