NCT ID NCT05864937

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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

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.

Summary

This study looked at 363 women with a history of three or more miscarriages who carry a specific gene mutation (MTHFR C677T). Researchers compared two treatments during pregnancy: aspirin plus folic acid, or the same plus a blood thinner (enoxaparin). The goal was to see which approach better prevented another miscarriage. The study was retrospective, meaning it looked back at past medical records.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
aspirin, folic acid, and enoxaparin (a blood thinner)
What this could lead to
If effective, this combination could help prevent recurrent miscarriages in women with this specific gene mutation.
What could go wrong
This is a retrospective study, not a randomized trial, so results may be less reliable. The benefit of adding enoxaparin is uncertain and carries bleeding risks.
