Skin Subs vs Secondary Intention

May 11, 2026 updated by: Baylor Research Institute

Skin Substitutes Versus Secondary Intention Healing After Mohs Micrographic Surgery

The purpose of this study is to compare two ways of caring for wounds after Mohs micrographic surgery (MMS) for skin cancer using skin substitutes and secondary intention healing, to determine which option leads to better healing after Mohs surgery.

Study Overview

Status

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 is a randomized-controlled trial comparing two ways of caring for wounds after Mohs micrographic surgery for skin cancer: skin substitutes, which are special wound-healing materials that may help wounds heal, and secondary intention healing, a common method in which wounds are allowed to heal on their own. This research is being done because we do not yet know which option leads to better healing after Mohs surgery. Patients will be randomized into one of two groups and receive either the skin substitute or undergo secondary intention healing.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Adults 18 and older undergoing Mohs micrographic surgery
  • Wounds deemed clinically appropriate for secondary intention healing
  • Ability to adhere to daily wound care and follow-up visits
  • Willingness to consent to standardized medical photography

Exclusion Criteria:

  • Wounds requiring flap or graft reconstruction for structural/functional reasons
  • Active wound infection at time of reconstruction
  • Known allergy to any component of the skin substitute

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.
Active Comparator: Control Group
Biological: Secondary Intention Healing
Standard secondary intention healing with daily wound care only.
Active Comparator: Intervention Group
Biological: Skin Substitute
Application of a commercially available skin substitute (e.g., acellular dermal matrix or fish-skin xenograft) to the wound base followed by routine daily wound care.

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
Cosmetic Outcome Assessments
Time Frame: 12 weeks
Compare cosmetic outcomes at 12 weeks between wounds treated with (1) a skin substitute and (2) secondary intention healing alone. This will be done by a group of blinded independent reviewers using standardized photographs and the Patient and Observer Scar Assessment Scale (POSAS), which evaluates scar quality using a scale of 1-10, where 1 is "like normal skin" and 10 is the "worst imaginable".
12 weeks

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
Complete Wound Healing
Time Frame: 12 weeks
Assess the amount of time to took for the wound to heal completely, also defined as full epithelialization. This will be compared using a t-test model or the Mann-Whitney U tests. A t-test model uses an standard statistic test that is used to determine if there is significant differences between two groups. The Mann-Whitney U tests is a rank-sum test that is used to determine if there is a difference between two different groups.
12 weeks
Pain Scores
Time Frame: 12 weeks
Evaluate the patient-reported pain during the first 2 weeks of healing and weekly, at follow-up visits, until wound closure. Patients will verbally rating their pain on a scale of 1-10 where 1 is no pain and 10 is severe pain. Patient will keep a record of their daily pain levels and share the scores at their weekly follow-up visits.
12 weeks
Rate of Complications
Time Frame: 12 weeks
To determine the rate of complication and assess for infection, bleeding, hypergranulation, and unplanned interventions. During the follow-up visits the physician will conduct a visual assessment for these items and will use a chi-square or Fisher's exact tests. A Chi-Square test is a statistical tool that is used to determine if there is a different between expected and observed frequences in one or more category. Fisher's exact test is a tool used to determine if there are non-random associations between two categorical variables.
12 weeks
Scar Appearance
Time Frame: 12 weeks
To evaluate the patient-reported scar satisfaction by patients the Patient and Observer Scar Assessment Scale (POSAS), which evaluates scar quality using a scale of 1-10, where 1 is "like normal skin" and 10 is the "worst imaginable".
12 weeks
Treatment-Related Resource Consumption
Time Frame: 12 weeks
To evaluate the resource utilization and cost of the number of clinic visits by reviewing the patients electronic health record
12 weeks
Treatment-Related Resource Consumption
Time Frame: 12 weeks
To evaluate the resource utilization and cost of dressing supplies by reviewing the patients electronic health record.
12 weeks
Patient Productivity Loss
Time Frame: 12 weeks
To assess the loss of productivity due to patient-reported time off work, if feasible. This will be done by patients verbal self-report.
12 weeks
