Brief Summary:
The purpose of this study is to investigate the dosing frequency, wound healing (re-epithelialisation) and anti-scarring effects of one, three and five applications of two concentrations of intradermal RN1001 in healthy male subjects.
Detailed Description:
Subjects were randomised into two cohorts, to receive either 5 ng avotermin doses or 50 ng doses, with a minimum of 21 subjects per cohort. Within each cohort subjects were randomised into one of three dosing groups (7 subjects per group).
Subjects were to receive four 3 mm punch biopsies, two on the upper-inner aspect of each arm. One treatment was randomly allocated to one biopsy on one arm, with the opposite biopsy on the other arm set to receive the same treatment. The other treatment was administered to the other two biopsies (one on each arm. This allowed for control of possible positional effects on healing.
Three subjects per group received intradermal avotermin to one of the biopsies on each arm and intradermal placebo to the other biopsies. A different three subjects received intradermal avotermin to one of the biopsies on each arm and standard care only to the other biopsies. The final subject per group received intradermal placebo to one of the biopsies on each arm and standard care only to the other biopsy.
On day 0 biopsy sites were marked on both arms and following local anaesthesia avotermin, placebo or nothing was injected intradermally into the allocated sites. Subjects in dosing frequency group 1 (DFG 1) were dosed only once (day 0), subjects in DFG 2 were dosed three times (day 0, 1 and 2) and subjects in DFG 3 were dosed five times (day 0, 1, 2, 3 and 4).
On Day 5, all subjects had their punch biopsy wounds on one arm only re-dosed as per Day 0 and then excised with a 5 mm surgical ellipse. Subjects in DFG2 and DFG3 received further re-dosing on their excised punch biopsies as before, i.e. three doses for DFG2 and five doses for DFG3.
Subjects returned for a first follow-up at day 14 and then at months 2, 4 and 6 to examine for anti-scarring effects. At month 6 all scars were excised for histological examination.
