About this study
Official title: A Randomized Trial of 17 Alpha-Hydroxyprogesterone Caproate for Prevention of Preterm Birth in Nulliparous Women With a Short Cervix
The purpose of this study is to see if giving progesterone medication to pregnant women, who have never delivered a baby after 19 weeks of pregnancy and who have a short cervix, lowers the risk of early delivery and improves the health of their baby.
Read the detailed description
Preterm births, defined as the delivery of a baby less than 37 weeks of gestation, are responsible for the majority of neonatal mortality and morbidities. Studies have shown that a number of risk factors, including never having a baby before and having a short cervix are associated with early delivery. Recently the NICHD did a study in women who were pregnant again after having delivered preterm. It showed that giving 17 alpha-hydroxyprogesterone caproate (17P) medication during pregnancy decreased the chance of delivering another preterm baby by 34%. This placebo-controlled randomized clinical trial will address the primary research question: does treatment with 17P initiated before 23 weeks of gestation prevent delivery prior to 37 weeks in nulliparous women with a singleton gestation who have a short cervix?

17 alpha-hydroxyprogesterone caproateDrug
Also called 17 AHP
Coded study medication is sterile solution containing 250 mg/mL of 17 alpha-hydroxyprogesterone caproate in castor oil with benzyl benzoate and benzyl alcohol as a preservative; placebo is same without the active ingredient. Study drug is administered as weekly 1 ml intramuscular injections until 36 week 6 days of gestation or delivery, whichever occurs first.

Number of Participants With Apgar Score of Less Than 7 at 5 Minutes
The Apgar score is a simple method of quickly assessing the health and vital signs of a newborn baby created by and named after Dr. Virginia Apgar. Apgar testing assesses Appearance, Pulse, Grimace and Activity in a newborn and is typically done at one and five minutes after a baby is born, and it may be repeated at 10, 15, and 20 minutes if the score is low. The five criteria are each scored as 0, 1, or 2 (two being the best), and the total score is calculated by then adding the five values obtained. Agar scores of 0-3 are critically low, 4-6 are below normal, and indicate that the baby likely requires medical intervention, scores of 7+ are considered normal. The lower the Apgar score, the more alert the medical team should be to the possibility of the baby requiring intervention. Some components of the Apgar score are subjective, and there are cases in which a baby requires urgent medical treatment despite having a high Apgar score.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing 17 alpha-hydroxyprogesterone caproate in people with Preterm Delivery and Cervical Length, run by The George Washington University Biostatistics Center at 14 sites in United States.
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 18 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: stopped early, as of the sponsor's last update on 15 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 14 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. Some participants in this study may receive a placebo. 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?
Yes. Results are posted in the registry (first posted 11 Apr 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Participants Delivering Before 37 Weeks Gestation (time frame: Delivery before 37 weeks gestation). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00439374, which also lists 1 linked publication.
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 15 Jul 2019.
