Clinical Trial Comparing Standard Wound Closure Techniques Versus TissuGlu® Surgical Adhesive

December 3, 2013 updated by: Cohera Medical, Inc.

A Clinical Investigation for a Randomized Study Comparing Standard Wound Closure Technique With Drains (Control) to Standard Wound Closure Techniques Plus TissuGlu® and No Drains (Test) During Abdominoplasty

The purpose of this study is to determine if TissuGlu® Surgical Adhesive is safe and effective alternative to drains(standard of care) for fluid management following abdominoplasty. It is hypothesized that the use of the Cohera device will facilitate reduction or closure of dead space when applied to planar surfaces created during an abdominoplasty procedure.

Detailed Description

The Cohera TissuGlu® study is a pivotal, prospective clinical investigation for a randomized, controlled, multicenter non-inferiority study comparing standard wound closure technique with drains (control) to standard wound closure techniques plus TissuGlu® and no drains (test) during abdominoplasty. TissuGlu® will be applied to the test group prior to standard closure of the abdominal flap thereby eliminating the deadspace between the fascia and the flap. No closed suction drains will be inserted in the test group. The control group will receive closed suction drains per the standard of care. It is hypothesized that the elimination of deadspace in the wound in the test group will prevent post-surgical fluid from developing and causing seroma and that the number of invasive treatments related to aspirations in the test group will not be inferior to the management and removal of drains and aspirations for seroma in the control group. The study will be conducted with 130 patients (65 test, 65 control) at up to 5 sites.

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, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Number of Post-Operative Invasive Treatments
Time Frame: 90 Days

Number of Post-Operative Invasive Treatments, where Invasive Treatment is defined as one of the following events:

  • Removal of an in-dwelling drain;
  • Needle aspiration to remove fluid from a clinically-diagnosed palpable seroma;
  • Invasive action to the drain or drain wound such as repositioning or re-attaching the drain retention sutures;
  • Reinsertion of a drain
90 Days

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.
