What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AtosibanDrug

    Atosiban group will receive an atosiban bolus (6.75 mg) over 1 min then an intravenous infusion of 300mcg/min for 3 h followed by 100mcg/min for another 45h. If contractions continue or recur within 48 hours or the dilatation of the cervix progresses by 1 cm or more within 48 hours, atosiban will be stopped and the women will receive nifedipine as a 2nd line (see arm 2). If the second line fails and gestational age is less than 28 weeks, indomethacin will be administered as a 3rd line.

  • NifedipineDrug

    Nifedipine group: the initial dose will be 20 mg (one tab) orally every 20 min for 3 doses. If the contractions is inhibited, a maintenance dose of 20 - 40 mg every 6 h up to 48 h will be followed. If contractions continue or recur within 48 hours or the dilatation of the cervix progresses by 1 cm or more within 48 hours, nifedipine will be stopped and the women will receive atosiban as a 2nd line (see arm 2). If the second line fails and gestational age is less than 28 weeks, indomethacin will be administered as a 3rd line.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Atosiban and Nifedipine in people with Labor, Premature, run by Raed Salim at 1 site in Israel.

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 5 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: finished, as of the sponsor's last update on 13 Mar 2012. 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 Israel. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

delaying labor (time frame: for more than 48 hours after starting treatment). 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 NCT00599898, which also lists 5 linked publications.

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 13 Mar 2012.
