Study Overview

Brief Summary

This is a phase 2 study performed in diabetic foot ulcer (DFU) patients with chronic non-healing, neuro-ischemic wounds to investigate the safety, tolerability and efficacy of AUP1602-C.

Detailed Description

This is a phase 2 multi-centre, parallel arm, patient and central evaluator-blinded, randomized, SoC plus placebo-controlled study of the RP2D of AUP1602-C performed in DFU patients with non-healing wounds. The RP2D of AUP1602-C derived from phase 1 study is 2.5 x 10E8 CFU/cm2 ulcer area and is used in this study.

Exclusion Criteria

  • •Current or previous (within 30 days prior to start of run-in period) treatment of target ulcer with a treatment that could interfere with wound healing/IMP such as biological agents, growth factors, skin equivalents/substitutes (e.g., Regranex®, Apligraf®, or Dermagraft®), keratinocytes, platelet-rich-plasma, collagen products, blood products, placental products, oxygen therapy, topical steroids.
