Study information

Study designMulticentre randomised open label active controlled parallel group trial
Primary study designInterventional
Secondary study designRandomised controlled trial
Study setting(s)Hospital
Study typeTreatment
Scientific title
Study acronymTISCOVER
Study objectivesWe 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®.
Ethics approval(s)Received from local medical ethics committee
Health condition(s) or problem(s) studiedUlcera cruris venosa, ulcera cruris arterio(lo)scleroticum, ulcers of mixed origin
InterventionTwo 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 Vacuum 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 follow-up for the duration of 24 weeks.
Intervention typeOther
Primary outcome measureEffectiveness of treatment of therapy resistant, chronic ulcera cruris (>5 months open; >2 months with no sign of healing), with Tiscover®.
Secondary outcome measures1. 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®
Overall study start date15/10/2005
Completion date15/10/2007
