Trial summary

This pilot study of 12 patients will test the safety and efficacy of applying autologous, adipose-derived stromal cells (ASCs), uncultured, on a Stage III or IV pressure ulcer or diabetic foot ulcers. Patients will undergo a minimal risk liposuction procedure to withdraw 50-100 cc of adipose tissue. Read more about this study

About this study

Official title: A Pilot Study: Evaluating the Safety and Feasibility of Using Autologous Adipose-Derived Stromal Cells From Stromal Vascular Fraction (SVF) on Adults With Pressure Ulcers or Diabetic Foot Ulcers

This pilot study of 12 patients will test the safety and efficacy of applying autologous, adipose-derived stromal cells (ASCs), uncultured, on a Stage III or IV pressure ulcer or diabetic foot ulcers. Patients will undergo a minimal risk liposuction procedure to withdraw 50-100 cc of adipose tissue. The tissue would be processed to extract the stromal layer of cells that contain stem cells. The ASCs would be injected into a fibrin sealant to be applied to the wound. Patients would be followed for 6 weeks to assess wound healing and tolerance of the treatment.

Read the detailed description

Wound healing for Stage III and IV pressure ulcers or diabetic foot ulcers can take four to six weeks or longer and cost upwards of $40,000 to treat. Past studies have shown that adipose tissue contains progenitor cells or regenerative cells that can release multiple angiogenic growth factors and cytokines including vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF) and chemokine stromal cell-derived factor-1 (SDF-1). A current literature review revealed that there is research related to use of stem cells to enhance wound healing, in particular with ischemic or radiation-induced ulcers. However, there is limited research completed on use of stem cells or ASCs with pressure ulcers. The goal is to heal pressure ulcers faster and prevent further complications using the patient's own natural ASCs.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Adipose-derived stromal cellsBiological

    Also called ASC's

    Adipose-derived stromal cells contain stem cells which have been successful in enhancing wound healing. The product used as the carrier is a fibrin sealant called TISSEEL. Pre-pilot testing was done to verify viability of the stromal cells for up to 72 hours in the fibrin sealant.

Study groups in NCT02375802
Study groupRoleWhat they receive
ExperimentalExperimentalLiposuction will be done to extract 50-100 cc of adipose tissue which will be processed to obtain the stromal cells. The adipose-derived stromal cells will be injected into a fibrin sealant applicator and applied to the wound (intervention), Patients will receive 5.0x106 ASCs per cubic centimeter of wound area. The wound will be dressed with an occlusive dressing and soft silicone dressing. The dressing will remain in place for one week (minimally, 3 days). Follow-up will occur weekly for 6 weeks.
Receives: Biological: Adipose-derived stromal cells; Drug: Adipose-derived stromal cells

What is being measured

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

  1. Free of wound infection

    Symptoms include fever along with new or increasing pain, erythema, local warmth, swelling, purulent discharge, and/or malodor

    Measured: one week

Secondary outcomes (2)

  1. Liposuction procedure without complication

    Signs of adverse reactions to the liposuction procedure include an allergy to the Hunstad solution, infection at the puncture wound site or risk of bleeding at the puncture wound site. Risks include bleeding or infection at the site and bruising for approximately one week. No adverse consequences of fluid overload have been associated with low volume liposuction.

    Measured: one week

  2. Improved wound healing

    Wound healing is greater than 20% healing within two weeks documented by measurement of the wound bed or wound healing to less than the dermal layer documented by photography and agreement of healing between research nurse and wound physician consultant. Would not expect deterioration to a more severe level of tissue injury

    Measured: weekly observation for 6 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Adipose-derived stromal cells in people with Pressure Ulcer, run by Mayo Clinic 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 13 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: enrolling by invitation, as of the sponsor's last update on 14 Jan 2026. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Free of wound infection (time frame: one week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02375802, which also lists 13 linked publications.

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 14 Jan 2026.
