Seprafilm® Adhesion Barrier and Cesarean Delivery

April 22, 2024 updated by: Daniel Kiefer, Winthrop University Hospital

A Multicenter, Randomized, Controlled Trial of Seprafilm® Adhesion Barrier to Reduce Adhesion Formation Following Cesarean Delivery

A multicenter, randomized, controlled, single blinded study to evaluate the effectiveness of Seprafilm® Adhesion Barrier in reducing adhesion formation in cesarean deliveries. Primary outcome will be measurement of the extent and severity of adhesions at the time of subsequent cesarean delivery. Secondary outcomes will include measures of safety, operative times (ex., incision-delivery; total operative time).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Patients presenting to labor and delivery for delivery will be screened for eligibility. If a patient meets the inclusion and exclusion criteria, she will be offered enrollment in the study. After the project and informed consent are reviewed with the patient and all questions are answered, she will be asked to sign the informed consent. At this point, she will be considered a candidate for randomization.

If the patient subsequently undergoes a cesarean delivery, she will be randomized to either:

  1. Group A - Placement of Seprafilm® prior to abdominal closure
  2. Group B - Routine closure without placement of Seprafilm® The chances of being assigned to either group will be equal (i.e., 1:1 randomization). The patient will be blinded with regard to Seprafilm placement.

The investigators will collect additional data about the patient, her antepartum course, intra-operative events, and post-operative course. There are no additional tests or procedures ordered or performed during the hospital stay as part of this protocol. Enrollment in this study is not expected to alter the patient's length of stay.

The antepartum, operative, and post-operative care of the patient will as directed by the patient's physician and participating institutions's standard policies and procedures. This study in no way changes or directs the care the patient would receive, except with regard to the placement of Seprafilm® Adhesion Barrier.

A short-term telephone follow-up will be conducted approximately 6-8 weeks following randomization to assess for immediate post-operative complications.

If a patient becomes pregnant again and undergoes a repeat cesarean delivery at a participating institution, the location and severity of adhesions (if any) would be assessed at the time of repeat cesarean delivery. The investigators will extract additional data from the chart including operative times, blood loss, and complications. An evaluation of adhesions would conclude the patient's participation in the study.

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.

Ages Eligible for Study

18 years and older (Adult)

Accepts Healthy Volunteers

Yes

Description

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
Incidence of Adhesions
Time Frame: 3 to 5 years
The Percentage of participants with one or more adhesions, regardless of the extent or severity
3 to 5 years
Adhesion Score
Time Frame: 3 to 5 years
Adhesion score. Derived by assigning 1 point for filmy adhesion and 2 points for dense adhesions at each of 6 possible sites in the abdomen. Thus the score can range from 0 (i.e., no adhesions at any location) to 12 (dense adhesions at each site).
3 to 5 years

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

Post-operative Hemoglobin
Time Frame: 1 to 5 years
Hemoglobin level following randomization delivery - used to determine if there was a difference in blood loss between the two groups
1 to 5 years
Post-operative White Blood Cell Count

Post-operative White blood cell count following randomization delivery - used to determine if there was difference in immune response or infection between the groups

Post-Operative Complications
