Trial summary

Preeclampsia (Pre-E) is a hypertensive disease of pregnancy with multi-system involvement that usually occurs in the second half of pregnancy. Pre-E occurs in 5% to 7% of U.S. pregnancies, and is the third-leading cause of U.S. maternal death. Improvements to the current diagnostic paradigm have been evaluated. Read more about this study

Study population: Pregnant women 18 to 45 years of age and 28 0/7 to 36 6/7 weeks gestational age with a singleton fetus presenting to clinic/triage/Labor \& Delivery for evaluation of, but not limited to, one or more of the following: * new onset elevated blood pressure * pre-existing hypertension * new onset proteinuria or worsening of pre-existing proteinuria * other organ system findings including thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, and cerebral or visual symptoms

  • Diagnosis of Pre-E or anticipated delivery within 24 to 48 hours because of Pre-E with severe features including: persistent severe hypertension (systolic ≥160 or diastolic ≥110; thrombocytopenia <100,000; liver enzymes 2x above upper normal limit or >70 with severe persistent right upper quadrant (RUQ) or epigastric pain, new development of renal insufficiency; pulmonary edema; new-onset persistent cerebral or visual disturbances.
  • Major fetal anomaly or chromosomal aneuploidy
  • Current dialysis for kidney failure, including continuous ambulatory peritoneal dialysis
  • Eligibility criteria for the POSITIVE CONTROL group:
  • Pregnancy is non-viable or absence of cardiac activity
  • Major fetal anomaly or chromosomal aneuploidy

About this study

Preeclampsia (Pre-E) is a hypertensive disease of pregnancy with multi-system involvement that usually occurs in the second half of pregnancy. Pre-E occurs in 5% to 7% of U.S. pregnancies, and is the third-leading cause of U.S. maternal death. Improvements to the current diagnostic paradigm have been evaluated. However, no stand-alone diagnostic method has emerged that more accurately identifies women at risk for preeclampsia, warranting improvements in diagnosing Pre-E.

This sample collection study will obtain serum and urine samples from pregnant women who present with clinical signs, symptoms, or conditions contributing to the suspicion of Pre-E. Samples will be used to evaluate and validate the performance of an assay intended to aid in assessing the risk of Pre-E.

Read the detailed description

Eligible subjects will provide written informed consent after which demographic and baseline clinical data will be recorded.

Collection of whole blood and urine samples will be performed at one or more clinic visits from pregnant women carrying a single fetus with no known fetal abnormalities.

Interim study visits will continue every 14 days [+/- 3 days] until the subject either: 1) reaches 37 0/7 weeks' gestation, 2) develops Pre-E, 3) delivers, or 4) is lost to follow-up.

In addition, a group of pregnant women diagnosed with Pre-E will be enrolled as positive control cases.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Suspected and Pre-E cases determined by institutional standards (time frame: about 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02780414, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
