About this study

The purpose of this study is to determine the testing performance of real-time quantitative polymerase chain reaction and transcription mediated amplification by comparing test performance of these novel molecular tests to current 2021 CDC CS guidelines for maternal/neonatal dyads at risk for syphilis infection and to determine whether CS is associated with adverse neurodevelopmental outcomes.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Quantitative polymerase chain reaction (qPCR) assay for detection of Treponema pallidumDiagnostic test

    A quantitative polymerase chain reaction (qPCR) assay detects and quantifies DNA in a sample, and the qPCR assay used in this study targets the polA gene of T. pallidum to confirm presence of T. pallidum in a sample. Samples will be collected from the mother/newborn dyad at the time of birth. qPCR data will only be used to determine testing performance and will not be used in clinical management of study participants.

  • Aptima Treponema pallidum transcription-mediated amplification (TMA) assay for detection of Treponema pallidumDiagnostic test

    The Aptima transcription-mediated amplification (TMA) assay used in this study will target RNA of T. pallidum to confirm presence of T. pallidum in a sample. Samples will be collected from the mother/newborn dyad at the time of birth. TMA data will only be used to determine testing performance and will not be used in clinical management of study participants.

  • Center for Disease Control (CDC) Sexually Transmitted Infections (STI) 2021 Treatment Guidelines for diagnosis of syphilisOther

    Using the Center for Disease Control (CDC) Sexually Transmitted Infections (STI) 2021 Treatment Guidelines, new born syphilis infection is categorized by clinical providers at birth as follows: confirmed proven/highly probably, possible congenital syphilis (CS), CS less likely, or CS unlikely. These CS categories are determined using neonatal nontreponemal test results, physical exam of the infant, placental pathology, and maternal serologies and treatment history, and comparison of maternal and neonatal nontreponemal tiers. These data will be collected as part of standard clinical care.

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 2 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 3 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States. 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?

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 Irene Stafford, MD ((713) 500-6412, Irene.Stafford@uth.tmc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity of quantitative polymerase chain reaction (qPCR) assay for detecting T. pallidum (time frame: from the time of birth up to 96 hours after birth). The study lists 15 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 3 Nov 2025.
