Prevascar in African Continental Group Scarring
Study Details
Study Description
Brief Summary
There is considerable variation in scarring, within and between people, and between different ethnic groups. Individuals with more pigmented skin are more prone to severe scarring than those traditionally termed white. Prevascar is being developed by Renovo for use as a potential treatment for reducing scarring.
Renovo's histological analysis of wounds and scars in human non drug studies demonstrates an increase in wound and scar width in subjects of African Caribbean ancestry over a 12 month period.
It is hypothesised that IL-10 may be a potentially beneficial therapy for the reduction of scarring in Non Caucasians of African-Caribbean ancestry.
This Renovo clinical trial will be carried out primarily to establish the effects of four doses of Prevascar on 1cm incisional and excisional scars in subjects of African Continental Group ancestry, as compared to placebo, and to further investigate the safety and tolerance of intradermally injected Prevascar in wounds.

Outcome Measures
Primary Outcome Measures
- To assess the effects of Prevascar on resultant scars [13 months]
To investigate the effects of Prevascar on wound/scar width To investigate the effects of Prevascar on wound/scar tissue histology To investigate the effects of Prevascar on scar appearance NB: This is an exploratory study and hence all objectives are exploratory
