"These early results suggest that treatment with Sterilox Tx wound
irrigant solution (CE marked) could provide clinicians with an effective way of treating wounds and alleviating the pain of chronic leg ulcers especially for patients who have failed an initial course of standard therapy," said David W. Anderson, president of Sterilox Technologies Inc. "In addition, the
Typically venous leg ulcers affect older people where the most common
symptoms are chronic inflammation of the ulcerated leg, debility, pain (often
so severe that patients need to take sleeping tablets at night), and social
stigma from infection. According to the National Institutes of Health,
chronic wounds such as venous leg ulcers, pressure sores, ischemic ulcers and
diabetic foot ulcers, affect more than 4 million Americans each year and cost
about $9 billion to treat (NIH, http://www.clinicaltrials.gov/ct/gui/show/NCT00006437).
The standard treatment for leg ulcers consists of compression bandaging
combined with anti-bacterial dressings over a period of 12 to 24 weeks.
However around 30 percent of patients fail to respond to this treatment and become
long-term sufferers needing to undergo multiple and costly alternative
therapies in an attempt to alleviate their symptoms.
Sterilox Tx is a novel antiseptic solution comprising mainly hypochlorous
acid (>95 percent) as its active ingredient at pH 5.4 to 5.8. The solution has
demonstrated extremely rapid bactericidal, virucidal and fungicidal action
against many organisms.

Patients admitted to this clinical trial, which is ongoing, continued with their standard course of treatment but also received a 20-minute Sterilox Tx treatment. Initially, this was conducted twice weekly for three weeks and then once per week for nine weeks.
Bacterial cell count studies showed that after one treatment with

the solution's combined activities: as a potent microbiocide and its ability
to aid the healing process by not inhibiting normal cell growth.
These early trial results were presented to the wound care community at
the 2nd World Union of Wound Healing Societies Congress in Paris held in July.
Sterilox Technologies Inc. is now in active discussion with a number of commercial partners to help introduce this novel approach more widely.
