About this study

This is a prospective, within-subject randomized, single blinded study designed to follow up to forty-two (42) qualified and consenting adult females, 18-65 years of age scheduled for elective breast reduction surgery using a standard inverted Wise (inverted "T") incision pattern

Read the detailed description

This is a prospective, within-subject randomized, single blinded study designed to follow up to forty-two (42) qualified and consenting adult females, 18-65 years of age scheduled for elective breast reduction surgery using a standard inverted Wise (inverted "T") incision pattern. Subjects will be randomized to the method of closure and wound support of the symmetrical vertical breast incisions. On the intervention side subjects will have FMTBs applied for final layer closure of the vertical breast incision and will continue with repeat application every two weeks for ongoing wound support for a total of 8 weeks of therapy. On the control side standard suture closure and wound dressings will be utilized. Patients will be evaluated at two-week intervals up until 8 weeks post-operative, then will have 3 additional follow up visits at 3-months, 6-months and 12-months post-operatively. The effects of the therapy will be analyzed during the follow up visits through photography, skin assessments and POSAS (Patient and Observer Scar Assessment Scale) results. A subgroup of 10 patients will also undergo biopsies of the area of interest at five time points throughout the study. Primary study outcomes include POSAS results and photographic assessment while secondary outcomes include scar volume/surface area, gene regulation and genetic analysis obtained via biopsies, collagen volume, skin assessments, colorimetry and time of length of adherence of the device.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patient and Observer Scar Assessment Scale (POSAS)- Patient Scores 12M

    Validated scale used to assess the scar quality after surgery from patient and observer (clinician) prospective.

    Scoring:

    Each of the six items on both the Observer and Patient scales is scored on a 10-point numerical rating scale, where:

    1 represents tissue that is like normal skin. 10 represents the worst scar imaginable for the observer, or the worst imaginable sensation/difference for the patient.

    The total score for each scale is the sum of the scores for the six items, ranging from 6 to 60. A higher score indicates a poorer scar quality while a lower scores indicates an ideal scar outcome.

    Measured: 12 Months

  2. Patient and Observer Scar Assessment Scale (POSAS)- Patient Scores 6M

    Validated scale used to assess the scar quality after surgery from patient and observer (clinician) prospective.

    Scoring:

    1 represents tissue that is like normal skin. 10 represents the worst scar imaginable for the observer, or the worst imaginable sensation/difference for the patient.

    The total score for each scale is the sum of the scores for the six items, ranging from 6 to 60. A higher score indicates a poorer scar quality while a lower scores indicates an ideal scar outcome.

    Measured: 6 Months

A study testing Side 1: Final layer closure with force modulating tissue bridges (FMTB), Side 1: Final layer dermal closure with poliglecaprone 25 suture and Side 2: Final layer closure with force modulating tissue bridges (FMTB) in people with Surgical Incision, run by University of Texas Southwestern Medical Center at 1 site in United States.

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 5 inclusion and 12 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 2 Jul 2025. 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 United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Jul 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Patient and Observer Scar Assessment Scale (POSAS)- Patient Scores 12M (time frame: 12 Months). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 2 Jul 2025.
