About this study
Official title: NOCETER, a Multicenter Double Blind Placebo-controlled Randomized Trial: Reduction of CEsareans in Post TERm Pregnancies: Impact of Outpatient Cervical Ripening With NO Donors
The purpose of this trial is to determine whether cervical ripening with isosorbide mononitrate reduce caesarean section in women with post term pregnancies.
Read the detailed description
The purpose of this trial is to determine whether cervical ripening with 40 mg of isosorbide mononitrate given intravaginally at 41+0, 41+2 and 41+4 weeks reduce cesarean section in nullipara with post term pregnancies. Treatments will be administered by midwifes in the maternity wards, women will be allowed to go back home in case of Bishop score<6. Otherwise labor will be induced with oxytocin. If undelivered at 41+5, women with Bishop score<6 will be induced with prostaglandins according to local protocols.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing IMN in people with Prolonged Pregnancy and Nulliparity, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.
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 11 inclusion and 11 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 1 Dec 2025. 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 France. 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?
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.
What does the primary outcome measure?
Number of cesarean sections (time frame: 10 days). 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 NCT00930618, 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 1 Dec 2025; AzTrials last refreshed its copy on 7 Nov 2026.
