  • Women only
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Threat of preterm labour (PTL) occurring between 24 and 34 WOA, defined according to validated criteria i.e. by (1) the presence of regular uterine contractions, lasting at least 30 seconds at a frequency ≥ 4 contractions every 30 minutes and confirmed by an external tocogram, (2) a cervical dilation of 3 cm or greater, to focus on true preterm labour, for the nulliparous women and 1-3 cm among primiparous women or multiparous and (3) a cervical obliteration >50%, or a cervix less than 25mm according to the echography, when this information is available. The first two criteria being mandatory, the third one optional as it is more subjective, or less likely to be available for every patient.
  • Person who has given written consent
  • Singleton pregnancy
  • Person who has given written consent
  • Group 1: Women of reproductive age who have never had a pregnancy, even if not completed to term.
  • Group 2: Single full-term, uncomplicated pregnancy (= out of hospital) older than 6 months.

Who cannot join

  • Pre-existing diabetes or gestational diabetes, morbid obesity (BMI > 35 kg/m2) as these situations modify the expression of MCP-1.

About this study

Official title: Evaluation of the Prognostic Value of Monocytes and Lymphocyte Phenotyping, Along With Intracellular MCP-1 Expression, to Predict Preterm Delivery for Women Hospitalized for Threat of Preterm Labor Between 24 and 34 Weeks of Amenorrhea: PhenoMAP Study

The threat of preterm labour (PTL) is the first cause of hospitalization in the course of pregnancy. Its diagnostic is based on clinical examination with a positive predictive value of about 40 %. The role of the Monocyte chemotactic protein-1 (MCP-1) in delivery has been suggested by its secretion in the amniotic fluid during labour and by the increase in the expression of its RNA messengers in the peripheral maternal blood. We have also shown that the proportion of MCP-1-expressing monocytes is higher in women with vaginal delivery compared with those with caesarean delivery prior the onset of labour.

OBJECTIVES : Primary To seek link between the respective proportions of circulating maternal monocyte and lymphocyte subpopulations and the true onset of PTL characterised by delivery occurring within 7 days post admission. Secondary: to (1) compare the predictive values of these new markers with those currently used, e.g. quantification of fœtal fibronectin and assessment of cervical length and effacement, (2) Compare the respective proportions of monocytes and lymphocyte subpopulations in maternal blood and fœtal membranes, (3) determine if a correlation exists between the activation markers expressed by maternal monocyte and lymphocyte subpopulations and the neonatal outcomes of preterm infants.

MATERIAL AND METHODS: 200 patients with a singleton pregnancy between 24 and 34 weeks of amenorrhea and complicated PTL, will be prospectively included in the maternity wards of Galway (Ireland) and of Dijon with the support of the perinatal network of Burgundy. A 2X5ml blood sample will be collected upon admission, at D1, D2, D4 and D6 for women who did not deliver within the first 7 days; finally, another blood sample will be drawn upon discharge. After delivery, foetal membranes will be collected to characterize and compare the various monocyte and lymphocyte subpopulations in the maternal blood. The characterization and the study of the level of activation of blood and foetal membrane cells will be performed using flow cytometry technique with suitable markers. The main judgment criteria will be the percentage of monocytes positively expressing MCP-1 for all three monocyte subpopulations ("inflammatory", "residents or patrollers" and "intermediates", according to CD14, CD16, CCR2 and MCP-1 markers. Lymphocyte subpopulations will be assessed using the following markers: CD45, CD3, CD4, CD8 (T lymphocytes), HLA-DR (activated T lymphocytes), CD19 (B lymphocytes), CD16/CD56 (NK Cells), intracellular IFN-gamma (Th1 lymphocytes), intracellular IL-4 (Th-2 lymphocytes), intracellular IL-17 and CCR6 (Th17 lymphocytes), CD4, CD25, Foxp3 and CD127 (Tregs). Univariate statistical analysis of quantitative data will be performed using the Mann and Witney test or ANOVA, after verification of the conditions of application. The comparisons of percentages will be done using Chi-square Pearson tests and the Fisher's exact test, as appropriate. The multivariate analysis will be performed using a stepwise descending analysis.

TRANSLATIONAL DIMENSION: The characterization of the various monocyte and lymphocyte subpopulations in the maternal blood and in the foetal membranes might constitute an " immunological signature " of the labour and therefore validate the relevance of a predictive marker for clinicians.

EXPECTED RESULTS AND PERSPECTIVES: The study of the various monocyte and lymphocyte subpopulations in the maternal blood will allow to better characterise the immunological mechanisms occurring at the start of premature labour and to identity predictive markers of the preterm delivery, to validate prospectively in order to optimize the management of PTL

What is being measured

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

  1. Number of women with delivering before 7 days

    Main outcome will be a delivery occurring within 7 days post admission for PTL. Women discharged from hospital before day 7 and not having delivered will not be censored; they will be classified as non-delivering before D7.

    Measured: 7 days

Who may be eligible to take part?

The sponsor lists 6 inclusion and 17 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 9 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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?

Number of women with delivering before 7 days (time frame: 7 days). 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 NCT01340222, 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 9 Feb 2026.
