Study summary

A multi-centered, prospective study, involving pregnant women presenting to the labor and delivery unit of collaborating clinical study sites with preterm labor and intact amniotic membranes with and without suspected Intra-Amniotic Infection (IAI).

Read the detailed description

A study on patients in preterm labor for whom the managing physician plans to perform amniocentesis to evaluate for possible infection using conventional, currently available methods. Vaginal fluid will be collected and analyzed and amniotic fluid will also. These tests will be run remotely and not reported to the clinician.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    All women eligible to participate

    All women presenting who sign the consent and found eligible will have a VF and AF sample taken and analyzed on the Perilynx Analyzer to measure AF and VF fluid. This does not affect their regular standard of care and diagnosis

    Diagnostic Test: Perilynx Analyzer to measure AF and VF fluid

Interventions

  • Diagnostic testPerilynx Analyzer to measure AF and VF fluid

    Hologic developed a rapid in-vitro diagnostic system composed of an analyzer and cassettes to identify women with intra-amniotic infection.

06

What researchers measure

Primary outcomes

  1. performance of vaginal fluid test

    To assess the performance of a vaginal fluid test for assessing risk of IAI in subjects presenting with preterm labor and intact membranes.

    Time frame: 18 months

  2. performance of amniocentesis test

    To assess the performance of a rapid amniotic fluid test to identify intraamniotic infection (IAI).

    Time frame: 18 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 30, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
