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 Results may not be published yet.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.

Summary

This study is looking at whether women who have had a blood clot while using hormones (like birth control pills or during pregnancy) have family members who are also more likely to have had a clot. Researchers will compare the family history of these women with that of women who used hormones but never had a clot. The goal is to see if family history is a better way to predict risk than current blood tests. No new treatments are being tested.

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 help identify women at higher risk of blood clots from hormones based on family history, improving prevention advice.
What could go wrong
This is an observational study, not a treatment trial. It may not prove cause and effect, and results might not apply to all populations.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Eligibility criteria: \- Propositi with objectively confirmed proximal deep vein thrombosis (i.e. ultrasonography) or pulmonary embolism (i.e. lung scanning) in women (18 to 50 years) while on hormonal exposure. Inclusion criteria * First-degree relatives (biological parents, brothers, sisters, children) of women of childbearing age 18-50 years (propositus) with a first MVTE in the hormonal setting and matched control women in the same hormonal setting who have never had MVTE, consenting to first-degree relatives being contacted to participate in the present study. * Written consent from propositi and family members. Exclusion criteria * First-degree relatives whose propositus received preventive antithrombotic medication during pregnancy or contraception. * Family members of propositus who have had superficial or muscular venous thrombosis * No information can be obtained on first-degree relatives. * Family members under 16 years of age. * Vulnerable persons other than minors aged 16 to 18 (guardianship, curatorship). * Not affiliated to or not benefiting from a health insurance scheme.
