About this study

Accurate prediction of preterm birth is critical for clinical management to improve the neonatal and maternal outcomes. A clinical challenge remains for current predicting biomarkers due to the complexity and multifactorial nature of underlying causes of preterm birth.

This study aims to evaluate the prediction performance of new maternal blood biomarkers (proteomic markers) on the occurrence of preterm birth.

Read the detailed description

Preterm birth (PTB), defined by delivery before 37 weeks of gestational age, represents a substantial public health challenge due to its elevated rates of neonatal morbidity and mortality worldwide. The prevalence of PTB exhibits variation, ranging from approximately 12-13% in the USA to 5-9% in other developed nations, underscoring a complex issue marked by regional disparities.

Emphasizing its significant public health ramifications, PTB is recognized as a primary contributor to mortality among children under five, particularly with 40% of deaths occurring within the first month of life in this demographic. Following PTB, infants face an increased vulnerability to severe complications like respiratory distress syndrome, intraventricular hemorrhage, and necrotizing enterocolitis, accentuating the acute threats to infant well-being and longevity. Addressing these early-life hurdles requires the formulation of robust strategies for prediction and prevention to alleviate the immediate hazards linked with premature birth.

Preventing PTB crucially depends on accurately identifying women at high risk. Interventions like vaginal progesterone and cervical cerclage are recommended for those with a short cervical length. However, the effectiveness of these strategies is frequently compromised by limitations in current screening methods, which struggle to accurately predict PTB. This underscores a significant gap in effectively identifying all at-risk women, underscoring the necessity for enhanced screening techniques to more precisely pinpoint women who would benefit from preventive interventions.

Current screening methods, primarily based on measuring cervical length and assessing historical risk factors, are inadequate in capturing the multifaceted nature of PTB risk, leading to missed opportunities for intervention and prevention. This inadequacy underscores the importance of developing methods that can more accurately identify women at high risk. Research efforts aimed at addressing these challenges suggest the potential of integrating new biomarkers and maternal characteristics into screening protocols to improve the predictive accuracy of PTB screenings.

Building upon the premise that the placenta plays a pivotal role in fetal health regulation, and that insights into the pathologic mechanisms leading to spontaneous preterm birth can be gleaned from the placental transcriptome, the investigators utilized existing transcriptomic data from the public domain, employing bioinformatics methodologies. This data was further complemented by quantitative proteomics analysis techniques using mass spectrometry. Through this integrated approach, the investigators have developed a novel PTB screening panel comprising three protein biomarkers. The efficacy and prediction performance of this three-protein predictor will be evaluated in this study with independent cohorts.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Prediction of preterm birth

    The primary outcome is the prediction of preterm birth, defined as pregnancy duration of less than 37 weeks. Preterm birth prediction score is calculated as sum of the z-score of 3 proteins' multiple of median (MoM) values.

    Measured: After blood draw during doctor's visit before 37 weeks of gestation

Secondary outcomes (1)
  1. Sensitivity, Specificity, Positive predictive value (PPV), Negative predictive value (NPV)

    Sensitivity, Specificity, PPV and NPV was calculate for identification the preterm birth cases using pre-defined threshold of prediction score.

    Measured: After blood draw during doctor's visit before 37 weeks of gestation

Questions about this trial

What is this clinical trial studying?

An observational study of Preterm Birth, run by HBI Solutions Inc. at 5 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Prediction of preterm birth (time frame: After blood draw during doctor's visit before 37 weeks of gestation). 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 NCT06664554, which also lists 2 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 5 Dec 2024.
