About this study
Official title: Laminaria Japonicum Followed by Misoprostol Versus Misoprostol Alone for Mid-Trimester Abortion Induction in Scarred Uterus: A Randomized Comparative Trial
The goal of this clinical trial is to compare the induction-to-abortion time interval between women receiving Laminaria tent followed by misoprostol and those receiving misoprostol alone for mid-trimester abortion induction in women with a scarred uterus. The main question it aims to answer is:
- Is the usage of laminaria japonicum as a mechanical dilator for the cervix followed by Prostaglandin E1 more effective and time saving than using prostaglandin E1 alone in induction of mid-trimester abortion in a previously scarred uterus? Researchers will compare induction-to-abortion time interval between women receiving Laminaria tent followed by misoprostol and those receiving misoprostol alone for mid-trimester abortion induction in women with a scarred uterus.

Participants in Group A: induction of abortion will be started with insertion of Laminaria japonicum for 12 hours to be followed by prostaglandin E1 methyl analogue, Misoprostol according to the FIGO 2017 recommendation.
Participants in Group B: induction of abortion will be carried out by prostaglandin E1 methyl analogue, Misoprostol according to the FIGO 2017 recommendation.

What is being measured
The primary outcome is the main question the study is designed to answer.
Induction-to-abortion interval time.
Time taken from the start of induction of abortion till occurrence of abortion
Measured: From enrollment to the end of abortion, an average of one week
Secondary outcomes (4)
Rate of Operative intervention
Operative intervention needed as suction \& evacuation or the need for hystrotomy
Measured: From enrollment to the end of abortion, an average of one week
Amount of vaginal bleeding
The amount of vaginal bleeding with be assessed visually and categorized into mild, moderate \& severe.
Measured: From enrollment to the end of abortion, an average of one week

As a complication of the usage of Misoprostol in previous scarred uterus is uterine rupture
Measured: From enrollment to the end of abortion, an average of one week
The amount of Misoprostol doses needed (microgram)
The doses of Misoprostol needed till expulsion of the fetus in each arm will be compared
Measured: Group A: after removal of Laminaria till expulsion of the fetus, an average of one week while for Group B: From enrollment to the end of abortion, an average of one week

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Misoprostol ( Cytotec) 200 microgram a tablet and Laminaria Tent in people with Induction of Abortion and Scarred Uterus, run by Pavly Maged Jimmy Fouad 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 4 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: finished, as of the sponsor's last update on 11 Mar 2026. 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 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?
Induction-to-abortion interval time. (time frame: From enrollment to the end of abortion, an average of one week). 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 NCT07465016, which also lists 12 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 11 Mar 2026.
