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.

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

N/A

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Population included ages 18- any age, males 50.5 % and females 49.5%, There was more males in the diabetic subset and more females in the venous subset.

Percentage by Race: White: 72.3, Black: 17.6, Hispanic: 4.8 and unknown: 5.3

Description

Inclusion Criteria:

  1. Theraskin applied to lower extremity wound during the study period.
  2. Over 18 years of age.
  3. Males and Females.
  4. lower Extremity wound due to diabetic neuropathy or venous insufficiency.
  5. Documented palpable pedal pulse (dorsalis pedis and/or posterior tibialis arteries and/or palpable bypass graft), or ankle brachial index (ABI) in the range of > 0.8 to < 1.1 or Tcpo2 > 40 mm Hg from the foot at the time of the initial allograft applicaton
  6. In subjects with multiple wounds only the largest wound receiving the allograft was included and considered the target wound
  7. Initial wound size >1 cm 2
  8. All wound locations within the lower extremity (defined as below the knee) and wound durations included
  9. Concomitant Negative pressure wound therapy was allowed as this could have been an anchoring technique for the allograft
  10. Concomitant antibiotics ( topical, oral, or intravenous) were allowed as it was not possible to determine whether administration of antibiotics was due to a true infection at the target wound site.

Exclusion Criteria:

  1. Wound etiologies other than diabetic neuropathy or nevous such as trauma, burns, sickle cell anemia, necrobiosis lipoidica , pyoderma gangrenosum.
  2. Wound not present for at least 30 days and showing lack of progression for at least 30 days prior to application of Theraskin.
  3. Other ulcer treatments besides study allograft during the study period ( study period definition: time of first allograft application up to 20 weeks) were not included in this study. These concomitant treatments specifically include hyperbaric oxygen treatments, venous ablation procedures, revascularization procedures including lower extremity bypass grafts or angioplasties or stents, application of additional growth factors, biologic products containing cells or other tissue-derived products, matrix components, or enzymatic debriders. Subjects were allowed to receive standard of care therapy with the study allograft, which included debridement, moist dressings or compression dressings depending on wound etiology, and off-weighting depending on wound location.
  4. Patients with revascularization procedures (defined as lower extremity bypass grafts, angioplasties, or stents) within 30 days of initial TheraSkin application were excluded
  5. Patients with successful surgical correction or intervention aimed at improving venous return in the target limb, such as venous ablation procedures, within 30 days of initial TheraSkin application were excluded

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Diabetic Foot Ulcers (DFU)
Study began with 214 consecutive patient; After excluding patients who did not meet the study criteria, the final eligible cohort consisted of 188 subjects, with 54 with diabetic foot ulcers
Other: Human Allograft (Theraskin)
Biologically active cryopreserved human skin allograft (Theraskin) was used on both cohorts, both diabetic foot ulcer and venous leg ulcer.
Venous Leg Ulcer (VLU)
Study began with 214 consecutive patient; After excluding patients who did not meet the study criteria, the final eligible cohort consisted of 188 subjects, with 134 venous leg ulcers.
Other: Human Allograft (Theraskin)
Biologically active cryopreserved human skin allograft (Theraskin) was used on both cohorts, both diabetic foot ulcer and venous leg ulcer.

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
Primary aim was to determine effectiveness of Theraskin together with standard of care
Time Frame: 12-20 weeks
Theraskin used together with standard of care in healing DFU and VLU wounds
12-20 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
Measure of effectiveness based on healing
Time Frame: 12-20 weeks
Effectiveness was measured based on the proportion of complete wound closures at 12 and 20 weeks
12-20 weeks

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 20, 2003

Primary Completion (ACTUAL)

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (ACTUAL)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
