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 Results may not be published yet.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.

Summary

This pilot trial tests whether using placental tissue analysis from a prior complicated pregnancy can guide treatment with the blood thinner enoxaparin to reduce the risk of recurrent adverse outcomes. The study enrolls women who had a previous pregnancy affected by early delivery, stillbirth, a small baby, or severe preeclampsia linked to a specific placental condition called maternal vascular malperfusion. Participants receive enoxaparin or standard care to see if it lowers the chance of similar problems in the next pregnancy.

What this could mean

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

Active substance
a blood thinner called enoxaparin (Lovenox)
What this could lead to
If it works, this approach could help prevent serious pregnancy complications like early delivery, stillbirth, or severe high blood pressure in women with a history of placental problems.
What could go wrong
This is a small pilot study with only 20 participants, so results may not apply broadly. Enoxaparin is a blood thinner and carries a risk of bleeding.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Eligibility Criteria: Inclusion (must meet all three criteria): 1. Subjects with a prior adverse outcome in a prior pregnancy. Adverse outcome is defined as prior singleton preterm birth ( \< 37 weeks), SGA infant (defined as birthweight \< 10th percentile), preeclampsia with severe features, or stillbirth (fetal demise after 20 weeks gestation), as certified by an obstetrician 2. Patients with maternal vascular malperfusion on pathology from pregnancy with prior adverse pregnancy outcome, as certified by a perinatal placental pathologist 3. Current singleton pregnancy at \<16 6/7 weeks gestational age. Exclusion Criteria: 1. Anticoagulation planned for current pregnancy (including warfarin, enoxaparin, heparin) 2. Known major fetal anomaly 3. Contraindication to enoxaparin: Specifically active major bleeding, known thrombocytopenia (platelets \<100), hypersensitivity to enoxaparin sodium, hypersensitivity to heparin or pork products, hypersensitivity to benzyl alcohol 4. Chronic kidney disease with eGFR\< 60 5. Known chronic liver disease with baseline AST/ALT \> 3 x upper limit of normal 6. Subjects with mechanical prosthetic heart valves
