Brief summary
This is a multi-centre, clinical trial. A sample size of 40 participants is sought. Up to 58 participants will be recruited to account for an estimated drop out rate of 30%. The study will include patients who have chronic, hard-to-heal, venous leg ulcers and use the following treatment procedure: 1) Cleansing the wound bed using local practices, at dressing change, then topically applying VitroGro ECM and covering with a non-adherent wound dressing. 2) Securing the dressing to the wound with tubifast and compression bandaging Dressings will be changed and the treatment procedure will be repeated once per week for Cohort 1 and twice per week for Cohort 2 when clinical, planimetry and photographic assessments will be made. The effectiveness of the treatment procedure will be evaluated on the basis of a 12 week treatment period. In the case of a wound that has healed before the 12 week end point, the treatment period will be shortened. Additional dressing or bandage changes, outside of the scheduled clinic visits, will be also be documented. The primary end point will be the reduction of ulcer size, or numbers healed at the 12 week point. Secondary end points are; reduction of pain, exudate and smell, condition of wound bed and surrounding skin and patient tolerance to the treatment provided and cost effectiveness.
Interventions
VitroGro ECM is a product that is designed to improve healing of chronic wounds by replacing a degraded extracellular matrix. VitroGro ECM is a sterile, non-invasive treatment that is biological in origin and applied topically. Participants are allocated based on enrollment number to one of two cohorts on the basis of treatment either once or twice per week for up to 12 weeks or until healed, whichever occurs first. When applied to the wound bed VitroGro ECM (0.014ug) provides a temporary scaffold to which the patients wound cells can attach and migrate upon.
