Inclusion criteria

Only patients who meet the following criteria will be approached.

  1. Singleton Pregnancy
  2. Previous single cesarean section
  3. At least 12 months have elapsed since the previous caesarean delivery
  4. Diagnosed with confirmed PROM at ≥ 34 weeks' gestation.
  5. Ruptured membranes have occurred ≤24 hours prior to inclusion in the study.
  6. Vertex presentation well applied to the cervix
  7. Found to have an unripe cervix in a speculum examination (Bishop score ≤6).
  8. Absence of significant and regular uterine contraction (\<3/10Min).
  9. Willingness to comply with the protocol for the duration of the study.
  10. Have signed an (including a TOLAC consent form).

Exclusion criteria

Exclusion Criteria:

Patients having any of the following conditions will be excluded from the study:

  1. Any for a vaginal delivery (i.e. placenta previa, non-vertex presentation, previous cesarean delivery \< 12 months).
  2. Regular uterine contractions (>3/10Min).
  3. Diagnosis of ruptured membranes was made over 24 hours prior to study inclusion.
  4. Meconium stained amniotic fluid.
  5. Evidence of chorio-amnionitis (T 37.6°C with uterine tenderness and maternal or fetal tachycardia or purulent discharge or WBC20.000)
  6. Suspected placental abruption or a significant hemorrhage.
  7. Non-reassuring fetal status (as determined by fetal heart rate monitoring and/or bio-physical profile) necessitating immediate intervention.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    Double balloon catheter for induction of labor

    in this group a trans-cervical double balloon catheter will be inserted. Following device insertion, 20 minutes of external monitoring is performed. The patient will be transferred to the Ob/Gyn ward for hospitalization. 12 hours after insertion of the device the balloons are deflated and the device removed. At this stage the patient is assessed for a second Bishop score and expectant management is resuming.

    Device: Double Balloon catheter for induction of labor

  • No intervention
    Expectant management

    Women in the expectant management group will be transferred to the Ob/Gyn ward for hospitalization and conservative management until spontaneous labor ensues.

Interventions

  • DeviceDouble Balloon catheter for induction of labor

    With the patient in lithotomy position or lying supine in bed, a speculum is inserted to visualise the cervix. The device is inserted into the cervix using long forceps until both balloons enter the cervical canal. Then, the uterine balloon is inflated with 20 ml of saline (by means of a 20 ml syringe). The device is then pulled out until stopped by the uterine balloon covering the internal cervical os. At this point the cervico-vaginal balloon located at the external os is inflated with 20 ml of saline and the speculum is removed. Then both balloons are additionally inflated with alternate increments of 20 ml normal saline to a total volume of 80 ml in each balloon. The device is loosely taped to the patient's inner thigh.

    Also known as: Atad Ripener Device

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2018 (actual). Primary completion is estimated for Mar 2020, 24 months after the start.

Of 119 non-industry interventional studies with no phase under Pregnancy Complications, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 48. This study's planned 24 months is close to that.

Counting every sponsor, half of 119 studies reached it within 26 months; a quarter within 12 and three quarters within 48.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 14, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
