Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are on high-dose antibiotics, certain steroids, or immunosuppressive drugs. It's best to discuss your current medications with the study team.

What data supports the effectiveness of the treatment ALLO-ASC-SHEET for diabetic foot ulcers?

Research shows that using allogeneic adipose-derived stem cell sheets can significantly improve wound healing in diabetic foot ulcers, with 82% of patients achieving complete wound closure in 12 weeks compared to 53% in the control group. This suggests that the treatment is effective and safe for promoting healing in diabetic wounds.12345

Is ALLO-ASC-SHEET safe for treating diabetic foot ulcers?

Research indicates that ALLO-ASC-SHEET, which contains adipose-derived stem cells, is generally safe for treating diabetic foot ulcers, as no serious adverse events were reported in a study involving 59 patients.14567

What makes the ALLO-ASC-SHEET treatment unique for diabetic foot ulcers?

The ALLO-ASC-SHEET treatment is unique because it uses allogeneic adipose-derived stem cells (ASCs) to promote wound healing in diabetic foot ulcers. These stem cells are applied as a sheet directly to the wound, accelerating healing by secreting growth factors that enhance blood vessel formation and tissue repair, which is different from traditional treatments that may not involve stem cells.23458

What is the purpose of this trial?

This trial is testing a special cell-based sheet called ALLO-ASC-SHEET to help heal foot ulcers in diabetic patients. The sheet creates a good environment for the wound to heal faster.

Eligibility Criteria

Adults aged 18-80 with Type I or II diabetes and a Wagner Grade II foot ulcer between 1.5 cm2 and 15 cm2 that hasn't reached the bone, is free of dead tissue and infection, has good blood flow around it, and has been present for over 4 weeks. Excludes those with certain immune responses, non-diabetic ulcers, severe infections or liver/kidney issues, high HbA1c levels (>10%), allergies to specific proteins or glues, recent other treatments or trials participation.

Inclusion Criteria

The range of Ankle Brachial Index (ABI) is within a certain range. C. The transcutaneous oxygen pressure (TcPO2) is above a certain level.
I have a grade II ulcer that affects muscle or tendon but not bone.
My ulcer is clean and shows no signs of infection.

Findings from Research

A review of 11 randomized controlled trials found that adding allogeneic skin substitutes and human placental membrane allografts to standard wound care significantly increases the healing rates of diabetic foot ulcers (DFUs) at 6 and 12 weeks.
One study suggested that placental membrane allografts may be more effective than allogeneic skin substitutes, but more research is needed to confirm this finding.

A 57-year-old woman with a 20-day diabetic foot ulcer (DFU) showed significant healing after treatment with placenta-derived mesenchymal stem cells (PDMSCs) hydrogel, indicating its potential efficacy in wound repair.
The treatment was safe, with no complications or recurrence of the ulcer observed over a 6-month follow-up period, suggesting that PDMSCs hydrogel could be a promising new approach for managing DFUs.

Autologous adipose-derived stem cells (ASCs) from diabetic mice (DMA) demonstrated comparable effectiveness to nondiabetic ASCs in promoting wound healing, improving angiogenesis, and enhancing tissue regeneration in diabetic wounds, based on a study involving 36 db/db mice.
Despite some limitations in osteogenesis, DMAs showed similar capabilities in adipogenesis and overall therapeutic potential, suggesting that using a patient's own stem cells could be a viable treatment option for diabetic wounds without the risks associated with donor cells.
