Predictive of Biomarkers of Healing in Chronic Venous Ulceration of the Lower Limb (MOJITO)
Clinical Study to Identify Biological Markers to Predict Wound Healing in Patients With Chronic Venous Ulceration of the Lower Limb
Chronic venous ulceration of the lower limb poses a significant problem to patients and healthcare providers alike. 1% of the population of Western countries have either an open or healed chronic venous ulcer.
However, the pathophysiological abnormalities are not entirely clear in how raised venous pressure translates into the changes seen in the skin culminating in an open ulcer. The standard treatment of this condition in the United Kingdom is to undertaken compression bandaging of the lower limb.
In order to further their knowledge of venous ulceration, the investigators seek to determine the biological profile of venous ulcers over a maximum of twenty-eight weeks and by dividing the groups into healing and non-healing wounds, the investigators may be able to demonstrate a difference in the biological profile.
This work may provide insights into predicting who will respond to treatment and targets for treatment in the future.
Study Overview
Status
Conditions
Detailed Description
Forty patients with chronic venous ulceration of the lower limb who meet the inclusion criteria will be entered into the study and assessed over a twenty week period with assessments at week 0, 1, 2, 4, 8, 12 and 20. Urine, serum and ulcer fluid will be sampled.
If the ulcer has not healed, further assessments using an approved biological dressing will be undertaken at weeks 20, 21, 22, 23, 25 and 28 with further sampling of ulcer fluid, urine and serum.
Samples will undergo metabolic profiling using established metabonomic techniques developed at Imperial College.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Biological profile of healing venous ulcers versus non-healing venous ulcers
Time Frame: 20 weeks
|
Repeated assays at weeks 0, 1, 2, 4, 8, 12 and 20.
Markers of wound healing and metabonomic assays.
Ulcers will be stratified into healing and non healing and differences in the biological profiles will be determined using multivariate statistical analysis.
|
20 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Differential biological response in non healing ulcers treated with a biological dressing.
Time Frame: 8 weeks
|
Non healing ulcers at twenty weeks will be treated in addition to standard dressing with a biological augmented dressing approved for use in the UK.
This will determine if an alternative biological profile can be obtained representing a 'healing' response.

8 weeks
