Cicatrix Clinical Trial
Official title:
A Single Site, Placebo and Standard Care Controlled, Double Blind, Randomised Trial to Investigate the Efficacy of Four Doses of Zesteem in Accelerating Early Wound Healing of Punch Biopsy Skin Wounds.
The purpose of this study is to investigate early wound healing of one application of four different doses of intradermal Zesteem (17β-Estradiol) in male subjects and female subjects two years post-menopausal.
Each subject received a total of six, 3mm punch biopsy wounds; three wounds to the upper
inner aspect of each arm. Each punch biopsy site was randomly allocated to receive one of
six treatments: Zesteem (0.02μg, 0.1μg, 0.2μg and 0.4μg/100μl), Placebo (vehicle), and
Standard Care (moist wound healing dressings) only.
Zesteem and Placebo were administered to marked, anaesthetised sites, by intradermal
injection 10 to 30 minutes before wounding. Sites randomised to receive Standard Care only
received no additional treatment before wounding. After wounding, all sites received moist
wound healing dressings (Standard Care).
Three days after wounding, all biopsy sites were anaesthetised and the wounds excised using
a 5mm punch biopsy, for histological analysis. The Investigator closed all excision sites
using sutures and Steri-strips to achieve a cosmetically acceptable result. Subjects
attended a post-trial follow-up visit (13-18 days after dosing) where their sutures were
removed and final safety assessments were performed.
