About this study

Official title: Evaluation of the Safety and Efficacy of an Advanced Therapy Medicinal Product Containing Live ASCs in the Treatment of Diabetic Foot Syndrome - a Double-blind, Randomized Study.

The goal of this study is to evaluate the safety and efficacy of an advanced therapy medicinal product containing live allogeneic adipose-derived mesenchymal stem cells (ADSC/ASC) for the treatment of diabetic foot ulcers in a randomized, double-blind, three-arm study.

Read the detailed description

Patients will be randomized and assigned to one of three study groups and will receive the following study treatments: 1) two doses of cell solution; 2) one dose of cell solution and one dose of placebo solution; or 3) two doses of placebo solution. During the study, patients will attend weekly visits for routine monitoring and standard-of-care (SOC) treatment. The IMP or placebo will be administered two weeks apart, on days 0 and 14. Control visits are scheduled on days 7, 21, 28, 35, and 42, for a total of seven visits during the active phase of the study. Follow-up visits will be conducted 8, 26, and 52 weeks after the last visit of the active phase (day 42).

What is being measured

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

  1. Change in wound size (%) at 6 weeks after first study treatment administration compared to baseline with the actual wound size measured by the independent assessor.

    Percentage change in wound size, measured by an independent assessor using a standardized wound area measurement method. The calculation is based on the difference between the baseline wound size and the wound size at 6 weeks, expressed as a percentage of the baseline value.

    Measured: 6 weeks after the first administration

  2. Type, frequency and severity of adverse events (assessed according CTCAE v5.0); change from baseline of laboratory parameters and selected vital signs of the participants.

    Adverse events will be assessed based on type, frequency, and severity according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Changes from baseline in laboratory parameters and selected vital signs will be evaluated using standardized clinical measurement methods.

    Measured: 6 weeks after the first administration

Secondary outcomes (6)
  1. Early efficacy of the allogenic ADSC/ASC defined as percentage of patients with significant clinical success defined as complete wound closure (100% epithelialization), or partial epithelialization of the wound (>50% epithelialization)

    The percentage of patients achieving significant clinical success, defined as either complete wound closure (100% epithelialization) or partial epithelialization of the wound (>50%). Wound epithelialization will be assessed using standardized wound assessment criteria by an independent assessor.

    Measured: 6 weeks after the first administration

  2. Long-term efficacy of the allogenic ADSC/ASC defined as percentage of patients with significant clinical success defined as complete wound closure (100% epithelialization), or partial epithelialization of the wound (>50% epithelialization) over time.

    The percentage of patients achieving significant clinical success, defined as either complete wound closure (100% epithelialization) or partial epithelialization of the wound (>50%), assessed over time. Wound epithelialization will be evaluated using standardized wound assessment criteria by an independent assessor at predefined time points.

    Measured: Through study completion, an average of 1 year

  3. The dynamics of wound healing defined as the time required for patients to reach the wound size reduction thresholds: 50% reduction of the wound; maximum reduction of the wound area (%); complete wound healing .

    The time required for patients to achieve predefined wound size reduction thresholds, including 50% wound size reduction, maximum wound area reduction (percentage), and complete wound healing (100% epithelialization). Wound size will be measured using standardized wound assessment methods by an independent assessor at predefined time points.

    Measured: 6 weeks after the first administration and through study completion, an average of 1 year

  4. Absolute change in the wound-associated pain perception over time assessed by the patient using visual analogue scale.

    Evaluation of the wound-associated pain, assessed by the patient using visual analogue scale. The minimum value is 0 and means "no pain" and the maximum value is 10 and means "the worst possible pain". The lower value the better outcome.

    Measured: 6 weeks after the first administration and through study completion, an average of 1 year

  5. Additional safety parameters such as wound infection requiring antibiotic treatment expressed as total number of patients, and number of antibiotic therapies per patient.

    The total number of patients with wound infections requiring antibiotic treatment and the number of antibiotic therapy courses per patient. Infections will be assessed based on clinical criteria and standard medical guidelines.

    Measured: 6 weeks after the first administration and through study completion, an average of 1 year .

  6. Changes in quality of life parameters assessed by the dedicated QoL questionnaire.

    Evaluation of the patient's quality of life, assessed by the dedicated QoL questionnaire. The QoL questionnaire consists of 10 questions. Each question is scored 1 to 5. The minimum score is 10 and it means "the best possible state of health", and the maximum score is 50, which means ,,the worst possible state of health".

    Measured: 6 weeks after the first administration and through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Allogeneic ADSC/ASC (alloADSC-DFU-RL) in people with Diabetic Foot Ulcer, run by Medical University of Warsaw at 1 site in Poland.

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 12 inclusion and 23 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: looking for participants now, as of the sponsor's last update on 26 Oct 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 Poland. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Contact Beata Mrozikiewicz-Rakowska, Assoc.Prof. (+48 225690529, klinendo@bielanski.med.pl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in wound size (%) at 6 weeks after first study treatment administration compared to baseline with the actual wound size measured by the independent assessor. (time frame: 6 weeks after the first administration). The study lists 2 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 26 Oct 2026.
