The proof of safety and tolerability of APOSEC™ is the primary objective. The secondary objective is to measure the extent of wound healing of APOSEC™.', 'detailedDescription': 'APOSEC™ is a human product derived from lyophilized conditional medium of peripheral blood mononuclear cells (PBMC) following 24 hours cultivation after irradiation with 60Gy. The soluble factors produced by these factors (secretome) have regenerative functions and enhance wound healing due to the activation of signaling cascades involved in the cell migration, proliferation and cell survival. The product also possesses strong angiogenic properties as well in vivo and in vitro. APOSEC™ is intended for topical use only, to promote healing of wounds in association with standard wound care. Standard wound care includes initial debridement, avoidance and treatment of wound related infections and a non-weight-bearing regime to decrease the pressure on the wound.\n\nThe verum APOSEC™ is processed as lyophilisate and resuspended in Nugel for the final formulation. It will be compared with a placebo, a cell-free parallel produced cell-free control lyophilisate that is finally formulated in Nugel as well.\n\n10 eligible healthy volunteers will consecutively be allocated to 2 different dose groups of APOSEC™ in a dose escalation scheme. The first 5 subjects in group A receive the low dose of APOSEC™ (12.5\\*10\\^6 lyophilized PBMC/mL), the subsequent 5 subjects in group B will receive the high dose of APOSEC™ (25\\*10\\^6 lyophilized PBMC/mL). Each volunteer will receive both Verum and Placebo on two artificial wounds on the inner upper non-dominant arm.
