Detailed Description
Subjects were allocated to two groups. Group 1 had scheduled visits on Day 0, 1, 3 and 4 while group 2 were scheduled for Day 0, 1, 5 and 6. Follow-up post-trial safety assessments were made on Day 10-20.
On Day 0 each subject received a total of four 1cm incision wounds; two each to the upper, inner aspect of each arm. Two areas for incision were marked out on the inner aspect of each upper arm and anaesthetised before intradermal injection of Juvista or placebo. One incision site on each arm received a dose of 50ng/100μl Juvista and the other incision site received Placebo. Following injection a full thickness 1cm incision was made along the marked site.
On Day 1 all subjects were re-injected with the same dose of Juvista or placebo, 100μl to each wound margin (200μl per wound site).
On Day 3 subjects in Group 1 were re-dosed with 200μl Juvista or Placebo per site (100μl per linear cm approximated wound margin) in Arm 1. These sites were then excised with an elliptical excision. On Day 4 the same subjects received another dose of Juvista or placebo as before.
Subjects in group 2 received the same treatment to their Arm 1 as those in group 1, except on Day 5 and 6.
All wounds were monitored and photographed at two monthly intervals over the course of 6 months. At month 6, all incision sites on Arm 2 for both groups were excised.
All excised wounds were snap frozen for genomic analysis.

Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Healthy, Caucasian, male subjects aged 18-45 years inclusive.
- Weight between 60-100 kg and a BMI within the permitted range for their height using Quetelet's index - weight (kg)/height²(m). The permitted index is between 18-28.
- Non-smokers, or ex-smokers that have not smoked for at least 3 months prior to screening.
Exclusion Criteria:
- Subjects who have history or evidence of hypertrophic or keloid scarring or with tattoos or previous scars in the area to be biopsied.
- Afro-Caribbean subjects are excluded because of the increased susceptibility to hypertrophic and keloid scarring.
- Subjects who have evidence of any past or present clinically significant disease, particularly coagulation disorders, immuno-mediated conditions and skin diseases and allergies, such as clinically significant eczema.
- Subjects with a history of clinically significant allergies, especially drug hypersensitivity to lignocaine or allergy to surgical dressings to be used in this trial.
- Subjects with any clinically significant abnormality following review of pre-trial laboratory data and physical examination.
- Subjects who are taking, or have taken, certain prescribed or investigational drugs in the three weeks prior to Day 0 and in particular topical or systemic steroids, anti-inflammatory and anti-coagulant drugs. Certain drugs are not excluded in this trial. These include OTC analgesics including paracetamol and codeine, vitamin and mineral supplements and OTC cold remedies.
- Subjects who drink more than 28 units of alcohol per week (1 unit = 1/2 pint of beer (285mls) or 25ml of spirits or 1 glass of wine).
- Subjects who have evidence of drug abuse.
- Subjects who are known to have or had serum hepatitis or who are carriers of the hepatitis B surface antigen or hepatitis C antibody. Subjects with previous vaccination against Hepatitis B are not excluded per se.
- Subjects who are known to have or had serum hepatitis or who are carriers of the hepatitis B core antibody and who show less than 10 units per litre of Anti-HBs.
- Subjects who have previously had a positive result to the test for HIV antibodies, or who admit to belonging to a high risk group.
- In the opinion of the investigator, a subject who is not likely to complete the trial for what ever reason.
