Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This randomized controlled study is designed to:

  1. To assess and compare the Bishop score when removing the DBD 12 hours' vs 6hours' after insertion.
  2. To compare the efficacy (vaginal delivery rate and time to VD) in the two arm groups

200 women are expected to be randomized in to two arms. One will be randomized to DBD removal after 12 hours and the other to DBD removal after 6 hours.

Each patient will sign an informed consent.

The following screening will be completed: medical and gynecological history, general physical and gynecological examination, ultrasonography to exclude contraindication to vaginal delivery or insertion if the DBD and non stress test (NST) for baseline. Bishop score will be assessed.

After confirming eligibility for study, randomization into the following groups will take place.

Insertion of the DBD and removal 6 hours following its insertion. Insertion of the DBD and removal 12 hours following its insertion.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: 12 hours
This arm is the standard management that includes insertion of the DBD into the cervical canal according to manufacture guidelines, removal after 12 hours followed by artificial rupture of membranes and oxytocin infusion according to departments protocol. (a total of 10 units of oxytocin is infused, initiated with 10 cc/h, increased by 10cc every 20-30 min until 3-5 contractions are present, total of not more than 120 cc\h)
Device: cervical ripening device
insertion of the double balloon device for 12 hours (standard care) vs 6 hours, following oxytocin IV infusion according local protocol guidelines as mentioned above

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
time from insertion of the DBD to delivery
Time Frame: minutes or hours from insertion to delivery, assessed up to an estimated total of 24 hours
the time from insertion of the DBD until delivery will be assessed for each patient from each arm by hours/minutes
minutes or hours from insertion to delivery, assessed up to an estimated total of 24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
rate of vaginal delivery
Time Frame: 1 year
calculation of the rate of vaginal delivery in each arm will be calculated by number of Vaginal deliveries in each arm and the percentage.
1 year
maternal and neonatal adverse events
Time Frame: 1 year
1 year

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
