Overview
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.

Eligibility Criteria
Inclusion Criteria
- •Clinically healthy male and female subjects aged 18-45 years inclusive
- •Weight between 40 and 150kg and a BMI within the permitted range for their height using Quetelet's index - weight (kg)/height²(m). The permitted index is between 15 - 55 kg/m2
Exclusion Criteria
- •Subjects who on direct questioning and physical examination have history or evidence of hypertrophic or keloid scarring or with tattoos or previous scars in the area to be biopsied
- •Subjects who have had surgery in the area to be biopsied within the previous 12 months
- •Afro-Caribbean subjects are excluded because of the increased susceptibility to hypertrophic and keloid scarring
- •Subjects, who on direct questioning and physical examination, have evidence of any past or present clinically significant disease, particularly coagulation disorders, diabetes, 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; or to any excipients or vehicle in the formulation or delivery vehicle
- •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 drugs in the four weeks prior to Day 0 and in particular topical or systemic steroids, anti-inflammatory, anti-coagulant, antiproliferative drugs and antibiotics Certain drugs are not excluded in this trial, including OTC analgesics such as paracetamol and codeine, vitamin and mineral supplements and OTC cold remedies and hormonal contraceptives. If antibiotics are required after Day 0, this will not exclude subjects from continuation in this trial and the data will be recorded in the CRF
- •Subjects who have taken part in a clinical trial within 3 months prior to admission to this trial, or who are currently participating in a clinical trial, whether an investigational drug was involved or not
- •Subjects who have any clinical evidence of severe ongoing or prolonged depression or mental illness
- •Subjects who smoke more than 20 cigarettes a day
