PLAC1 in Reproduction
NCT01277848 · View on ClinicalTrials.gov ↗
Study Summary
The PLAC1 gene is a recently described X-linked gene that maps to a region of the X chromosome thought to be important for normal fetal and placental development. Elevated levels of PLAC1 mRNA were detected in preeclampsia and appeared to be directly related to disease severity. PLAC1 may serve as a useful marker of placental dysfunction or threatened pregnancy. The objective of this study is to measure the prevalence of circulating anti-PLAC1 antibodies in pregnant maternal serum and correlate it with pregnancy outcome. It is likely that women with these antibodies are at higher risk for adverse pregnancy outcomes. Approximately 5% (50 of 1000) will be expected to have anti-PLAC1 antibodies based on previously reported data. The prevalence of these antibodies and their clinical impact on pregnancy outcomes will be determined. 1000 healthy, multiparous and primigravid women will be screened for anti-PLAC1 antibodies at their routine prenatal clinic visits. Subjects will be enrolled at their first clinic visit at USF Health, South Tampa Center, Department of Obstetrics. Blood (1.0 ml) will be obtained as part of the routine blood draw at the time of enrollment. Blood will only be collected when drawn as part of routine laboratory testing as determined by the primary care provider. Additional blood samples (1.0 ml) will be collected throughout pregnancy at the same time blood is obtained for routine or otherwise clinically indicated laboratory testing. A maximum of 5 samples will be collected through the pregnancy. Maternal demographic data will be collected and patients will be followed longitudinally to the completion of pregnancy to ascertain their clinical status during pregnancy, onset of premature labor, premature rupture of membranes, delivery date, and gestational age at delivery.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01277848
The ClinicalTrials.gov registry entry for NCT01277848 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 500 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of South Florida, which has 144 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Pregnancy appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01277848 reports 1 study location spanning 1 distinct geographic area — top geographies include Florida. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
