About this study
Official title: Effect Of Azithromycin On Pregnancy Prolongation In Women at Risk of Preterm Labour
The aim of this study is to evaluate the benefit of the addition of azithromycin to standard treatments to prolong pregnancy in women having intact membranes and is at risk of or in preterm labour.
Read the detailed description
Study Design:
Comparative controlled study.
Study site :
The study will be conducted at the department of Obstetrics and Gynecology at Beni-Suef University Hospital.
Study period:
The study will be conducted from 15th September 2022 till reaching the target number.
Study Population The control group will include pregnant women, having intact membranes and are at risk of or in preterm labour, administrating the standard treatments for prolongation of pregnancy.
The test group will involve pregnant women, having intact membranes and are at risk of or in preterm labour, administrating the standard treatments for prolongation of pregnancy plus prophylactic azithromycin.:500 mg PO once for 5 days every month.
Sample size:
The sample size was determined using G*Power Version 3.1.9.2 [computer software] (Franz Faul, Kiel, Germany),Power analysis for a chi-square test was conducted in G-POWER to determine a sufficient sample size using an alpha error of probability of 0.05, power of 0.95, a medium effect size (w = 0.3) and 1 degree of freedom. Based on the aforementioned assumptions, the desired sample size is 145. By calculating 25% drop out, so the least total sample size in both groups will be 200 patients (95 patients in each group).
Each patient will be subjected to:
Thorough history taking and examination. Investigations: Complete blood picture (CBC), bleeding profile , kidney function tests and liver function tests will be done.
Ultrasound: 2D Ultrasound assessing :
It will be carried out in Gynecology and Obstetrics department in Beni-Suef University Hospital, ultrasonography criteria: Ultrasound biometry of the fetus is now the gold standard for assessing fetal growth. The measurements most commonly used are the biparietal diameter, head circumference, abdominal circumference and femur length

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing azithromycin in people with Preterm Labor, run by Beni-Suef University at 1 site in Egypt.
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 3 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 2 Aug 2023. 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 Egypt. 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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Results are not available in the source record.
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?
Gestational age at time of delivery (time frame: 9 months). 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 2 Aug 2023; AzTrials last refreshed its copy on 8 Nov 2026.
