About this study
Official title: Intraoperative Cellular Reprogramming-Enhanced Skin Transplantation for Diabetic Foot Ulcers: A Randomized Clinical Trial
Diabetic foot ulcer is one of the refractory wounds and always poses many challenges in clinical practice. This study was conducted to have a prospective, randomised, controlled study compare the safety and efficacy of the autologous skin cell with skin graft (experiment group) with split-thickness skin graft (STSG, control group) alone on treating diabetic foot ulcers.
Read the detailed description
The primary objective of this study is to assess the effectiveness and safety of autologous skin cell with skin graft (experiment group) vs. skin graft (control group) for the treatment of non-healing diabetic foot ulcers. Our hypothesis is that the methods of experiment group is better than the control group.

Questions about this trial
What is this clinical trial studying?
A study testing autologous skin cell and skin graft in people with Diabetic Foot Ulcer, run by Hu Zhicheng at 1 site in China.

Who may be eligible to take part?
The sponsor lists 6 inclusion and 10 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 18 Feb 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 China. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
healing rate (time frame: postsurgery week 2). 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 18 Feb 2026.
