Brief Summary

The purpose of this study was to investigate the safety and toleration of various doses of intradermal Juvidex (mannose-6-phosphate) administered to punch biopsies of normal subjects.

Detailed Description

Each subject received a total of four wounds, two 3mm punch biopsies (at least 5cm apart) to the upper, inner aspect of each arm.

Subjects served as their own control, i.e. one punch biopsy on Arm 1 received Juvidex and the other punch biopsy received Placebo or Standard Care. Arm 2 punch biopsies received the same treatments as for Arm 1 but in reverse, i.e. treatments were matched across the arms.

On Day 0 the two areas for punch biopsies on Arm 1 were marked and anaesthetised and randomised to receive Juvidex or Placebo. Prior to wounding sites were injected intradermally with 100μl investigational product per site. Juvidex was dosed at 50, 100, 200, 300, 400, and 600mM.

On Day 1 (24 h later) wounds were dosed as on Day 0 but with 200μl investigational product per site. On Day 3 the biopsy sites on Arm 1 were excised to determine re-epithelialisation.

Arm 2 treatments and punch biopsies were carried out on Day 3, with further dosing 24 h later on Day 4 (as with Arm 1 wounding and treatments). These biopsy sites were excised on Day 8 of the study to obtain a 5 day-old wound.

The randomisation of the treatment allowed for control of possible positional effects on healing. One subject in each group was randomised to receive only Placebo and Standard Care to their biopsy wounds.
