NCT02565264

Brief Summary

This study is an open prospective clinical trial. The objective is to evaluate the effect of autologous exosomes rich plasma on cutaneous wound healing. The participants are patients with intractable cutaneous ulcers (e.g. rheumatic disease, peripheral arterial disease, chronic venous insufficiency, decubitus or burns). The participants will be treated autologous exosomes rich plasma every day for 28 days. The cutaneous wound healing will be evaluated by the length, width and depth of the wound.

Outcome Measures

Primary Outcomes (3)

  • Ulcer size (length, mm)

    28 days

  • Ulcer size (width, mm)

    28 days

  • Ulcer size (depth, mm)

    28 days

Secondary Outcomes (1)

Study Arms (1)

plasma-derived exosomes

EXPERIMENTAL

plasma-derived exosomes

Other: plasma-derived exosomes

Interventions

Plasma samples from the participants will be filtered through 0.45 μm and 0.20 μm filters. The samples will be filtered through 0.02 μm filter to trap exosomes with the filter. Saline solution will be loaded from the other side of the 0.02 μm filter to obtain exosome rich buffer. The plasma-derived exosomes will be applied to the participants' ulcers daily for 28 days.
