About this study

The PROMISSE Study is an observational study of 700 pregnant patients, enrolled at nine major clinical centers. The purpose of the study is 1) to determine whether certain proteins (called complement split products) that can injure healthy organs can be used to predict poor pregnancy outcome in patients with systemic lupus erythematosus (SLE) and anti-phospholipid syndrome (APS), and/or 2) to determine whether elevated levels of circulating antiangiogenic factors predict pregnancy complications in patients with aPL antibodies and/or SLE.

Read the detailed description

Thrombosis and pregnancy loss are common features of systemic lupus erythematosus (SLE), particularly in the presence of antiphospholipid (aPL) antibodies. The in vivo mechanisms by which aPL antibodies lead to vascular events and, specifically, to recurrent fetal loss are largely unknown. Studies in a mouse model of antiphospholipid antibody syndrome (APS) indicate that in vivo complement activation is necessary for fetal loss caused by aPL antibodies. This study represents an effort to translate these research observations on the potential role of complement activation in the pathogenesis of aPL antibody-mediated pregnancy loss to a clinically relevant human study.

In addition, studies in humans and mice have shown 1) that the balance of circulating angiogenic and antiangiogenic factors predicts preeclampsia and fetal growth restriction in healthy women, 2) circulating antiangiogenic factors cause endothelial dysfunction and abnormal placental development in animal models, and 3) complement activation leads to elevated levels of circulating antiangiogenic factors and complement inhibition prevents increased levels of antiangiogenic factors, placental dysfunction and fetal growth restriction in a mouse model of APS. This study will permit testing the hypothesis that, like in healthy women, the balance of circulating angiogenic and antiangiogenic factors predict complications in women with SLE and APS and to translate the findings in animal models into humans.

The PROMISSE Study is a prospective observational study that will follow 700 pregnant patients who will be grouped and analyzed according to the presence or absence of aPL antibodies and preexisting SLE. The patients are followed regularly during the course of the pregnancy, collecting medical and obstetrical information as well as serial blood specimens for complement and cytokine assays. The data obtained will be analyzed and used to identify mechanisms and predictors of poor fetal outcome. We expect that the insights provided through this study will suggest means to prevent, arrest or modify these conditions.

This study is still under way. Results are not available in the source record yet.

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

Contact Marta M. Guerra, MS (212-774-7361, guerram@hss.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Otherwise unexplained fetal death occurring after 12 weeks gestation (time frame: End of pregnancy). The study lists 4 primary outcomes in all. 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 NCT00198068, which also lists 17 linked publications.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2026.
