简要总结

A double blind, Placebo (Vehicle) and Standard Care controlled, randomised study to investigate the clinical safety and toleration (including systemic pharmacokinetics), wound healing and antiscarring potential of two applications of intradermal RN1001 in healthy male subjects

详细描述

Double blind, randomised, Placebo and Standard Care controlled, single centre study. Each subject served as their own control, i.e. Arm 1 incisions/biopsies randomly received one of two treatments and Arm 2 incisions/biopsies received the same treatments as for Arm 1 but in reverse. The randomisation of the treatment allowed for control of possible positional effects on healing and subsequent scarring. Subjects were initially dosed and wounded (incisions and punch biopsies) on Day 0 and re-dosed on Day 1. On Day 3, Arm 1 incisions and punch biopsies were re-dosed as per Day 0 and excised, and re-dosed again on Day 4. Arm 2 punch biopsies were excised at Day 5 but not re-dosed. Healed incisions/scars on Arm 2 were excised for histological analysis after 12 months and not re-dosed. All subjects, regardless of treatment were treated according to best practices for moist wound healing.

排除标准

•Afro-Caribbean subjects are excluded because of the increased susceptibility to hypertrophic and keloid scarring.
•Subjects with tattoos or previous scars in the areas to be biopsied.
•Subjects, who on direct questioning and physical examination, have evidence of any past or present clinically significant disease and particularly coagulation disorders, immuno mediated conditions and skin diseases and allergies, such as eczema.

•Subjects with any clinically significant abnormality following review of pre study laboratory data and full physical examination.
•Subjects who are taking, or have taken, certain prescribed or investigational drug in the three weeks prior to Day 0 and in particular topical or systemic steroids, and anti-coagulant drugs. Certain drugs are not excluded in this trial. These include OTC analgesics including paracetamol and codeine, vitamin and mineral supplements, inhaled salbutamol, thyroxine replacement therapy, OTC cold remedies.
