Preterm BirthPhase 3PWKNCT02849301
Cervical Pessary in Women With Arrested Preterm Labor and Short Cervix
A Phase 3 study testing Arabin cervical pessary in people with Preterm Birth, run by Federico II University at 1 site in Italy.
Trial summary
Preterm birth (PTB), defined as birth between 20 and 36 6/7 weeks, is responsible for the majority of the neonatal morbidity and mortality in the United States, and 35% of all U.S. healthcare spending on infants. Globally, about 28% of the 4 million annual neonatal deaths are directly attributable to PTB. Read more about this study

About this study
Preterm birth (PTB), defined as birth between 20 and 36 6/7 weeks, is responsible for the majority of the neonatal morbidity and mortality in the United States, and 35% of all U.S. healthcare spending on infants. Globally, about 28% of the 4 million annual neonatal deaths are directly attributable to PTB.
Preterm labor (PTL) is the final pathway for about 50% of all PTB. Tocolytic agents are drugs that can slow or stop labor contractions in the attempt to delay births preceded by PTL. Primary tocolysis is defined as tocolysis given on initial presentation of women with PTL. In most of these women, PTL stops, but as their risk of PTB remains high, some have advocated use of maintenance tocolysis, i.e. tocolysis after arrested PTL. So far, no maintenance tocolytic agent has been shown to be beneficial in preventing PTB.
The aim of this study is to evaluate the efficacy of maintenance tocolysis with Arabin pessary compared to standard care in singleton gestations with arrested PTL and with short transvaginal ultrasound (TVU) cervical length (CL) <25mm

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Arabin cervical pessary in people with Preterm Birth, run by Federico II University at 1 site in Italy.
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 6 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The record says: withdrawn, as of the sponsor's last update on 19 Nov 2018. 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 Italy. 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
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?
Spontaneous preterm birth (SPTB) (time frame: Less than 34 weeks gestation). 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 19 Nov 2018; AzTrials last refreshed its copy on 7 Nov 2026.
