Tiscover

Tiscover is autologous full thickness cultured skin for healing of chronic, therapy resistant wounds.
Tiscover is an Advanced Tissue Medicinal Product (EU guideline in Regulation (EC) No 1394/2007). Tiscover is classified (by EMA) as a Tissue Engineered Product (TEP).
Tiscover consists of a dermal and epidermal layer, just like normal healthy skin. The interaction of the autologous dermal and epidermal cells ensure a secure secretion of chemokines, growth factors and cytokines into the non healing wound bed. Wound re-activation and reepithelialization occurs through the direct secretion and cover of the wound bed. Tiscover is constructed from 3mm punch biopsies in 3-week culture time.

Multicenter randomized clinical trial

Tiscover is currently in a phase II multicenter trial entitled: “A prospective, multicenter, randomised controlled phase II study in which patients with therapy resistant (arterio-) venous leg/foot ulcers are treated in an outpatient setting with an autologous cultured human living skin substitute (Tiscover®:
test group) or with Acellular donor dermis (AS210: control group) to determine the safety
and relative efficacy of both products”.
