Renovo, a Biopharmaceutical company involved in the development of drugs to improve the appearance of scars and enhance wound healing, are proposing to carry out research in improving the appearance of existing scars that are 2-6 months old using Juvista. Juvista has not previously been administered to pre-existing scars without surgical revision, but it is thought that some beneficial effects seen with Juvista in previous trials may also be seen when administered to existing scars whilst the scar is maturing. This proof of concept study will therefore investigate the effect of Juvista in Caucasian male and female patients when administered to scars that are between two and six months old.
