Outcome measures
Primary outcome
Effectiveness of treatment of therapy resistent, chronic ulcera cruris (>5 months open; >2 months with no sign of healing), with Tiscover.
Secondary outcome
1. Determine whether hospitalization and wound bed preparation have a beneficial effect;
2. Evaluate unforeseen toxicity due to Tiscover treatment;
3. Evaluate the durability of treatment with Tiscover;
4. Determine whether out-patient treatment with Tiscover is possible;
5. Compare the costs of Tiscover treatment with present costs for caring/treatment of inert ulcera cruris without Tiscover.
Background summary
An open, randomized, multicenter trial into the effectiveness of treatment of chronic wounds (ulcera cruris) with a new skin substitute. Tiscover is an autologous full-thickness skin substitute of 3 cm2. Recently 19 ulcers have been treated with Tiscover and in more than 60% of the cases complete closure occured within 8 weeks, without any side effects.
In total, 100 patients with ulcera cruris venosa, ulcera cruris arterio(lo)scleroticum or mixed origin (>6 months open; > 2 months with no sign of healing; size 5-100 cm2) will be included. They will be divided into an in-patient (n=40)and an out-patient (n=60) group - each consisting of a test and a control group. In the in-patient and out-patient groups, the wounds will be prepared with Vacume Assisted Closure therapy or acellula allodermis respectively. In the test group, Tiscover will then be applied and all groups will receive continued compression therapy. The reduction in ulcer size will be measured.
Statistical analysis: Two group continuity corrected c2 test with a 2 sided p-value of <0.050 being significant
The study is for a duration of 24 weeks for each patient.
Study objective
We hypothesize that ulcers treated with Tiscover will significantly decrease in size resulting in most cases in full healing, compared to the control group which is not treated with Tiscover.

Intervention
Two out-patient groups:
Control group (n=30): 1 week prior wound bed preparation with acellular allodermis;
Test group (n=30):1 week prior wound bed preparation with acellular allodermis followed by removal of allodermis and application of Tiscover;
Two in-patient groups:
Control group (n=20): 5 day prior wound bed preparation with Vacume Assisted Closure therapy (VAC);
Test group (n=20):5 day prior wound bed preparation with VAC followed by application of Tiscover.
All patients receive compression therapy.
All patients have a weekly followup for the duration of 24 weeks.
