About this study

Official title: Eficacia de Los Suplementos de Progesterona Natural en la prevención Del Parto pretérmino Gemelar

To assess the effectiveness of natural progesterone supplementation in preventing preterm births in twins.

Read the detailed description

Objective: To assess the effectiveness of natural progesterone supplementation in preventing preterm births in twins.

Study Design: National multicenter randomized double blind controlled clinical trial.

Setting: Six tertiary hospitals in the east of Spain (communities of Valencia and Murcia): Instituto Universitario IVI Valencia, Hospital Universitario La Fe (Valencia), Hospital Universitario Dr. Peset (Valencia), Hospital General Universitario (Alicante), Hospital Vega Baja de Orihuela (Alicante) y Hospital Virgen de la Arrixaca (Murcia).

Population: 246 bichorionic biamniotic twin pregnant women divided in three groups according to the allocated randomized treatment: (I) placebo (N=82); (II) 200 mg progesterone (N=82); and (III) 400 mg progesterone (N=82).

Methods: All participant women will self-administer two vaginal pessaries at bedtime containing the allocated treatment. Vaginal pessaries will be identical externally but will contain either placebo or 200 mg of natural progesterone (Laboratorios Effik, Madrid, Spain). The treatment will be applied from the 20th week until the 34th week (or until delivery if it occurred earlier). Control visits will be performed at 24, 28, 32 and 34 weeks. Pregnancies will be managed according to each local protocol. An external statistical analysis will be performed on intention to treat basis.

Main outcome measure: Preterm birth rate (<37 weeks). Secondary outcome measures: very preterm birth rate (<32 weeks); cervical length measured by vaginal ultrasound at each control visit; need for tocolytic treatments; rate of preterm premature rupture of membranes; and perinatal morbidity and mortality.

Estimated period of study: 2006-2008.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 200 mg of Progesterone and 400 mg Progesterone in people with Preterm Birth, run by Instituto Valenciano de Infertilidad, IVI VALENCIA at 1 site in Spain.

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 9 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 4 Apr 2013. 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 Spain. 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 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.

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 4 Apr 2013.
