Hatchtech Commences 2b Clinical Trial of New-Generation Head Lice Treatment DeOvo(TM)

MELBOURNE, Australia, May 2, 2011 /PRNewswire/ -- Venture-backed pharmaceutical company Hatchtech Pty Ltd has enrolled the first subjects for its Phase 2b clinical study to confirm the efficacy of its novel head lice treatment DeOvo.

This Phase 2b trial will evaluate the efficacy, safety and tolerability of two dose levels of a single application of DeOvo compared to vehicle. It will conducted in approximately 132 healthy subjects with head lice infestation, 2 years of age and older in two study centers in the United States.

Hatchtech's proprietary agent DeOvo is a topical formulation of a known metalloprotease inhibitor which targets certain proteases that are key to biological processes involved in insect hatch and survival.

Hatchtech Chairman Dr Paul Kelly commented: "This is a big milestone for Hatchtech. DeOvo is a next generation head lice treatment therapy that targets all life cycle stages of the parasite with a single 10 minute

application."

"We have previously demonstrated that this agent effectively treats eggs and crawling lice in a small number of infested adults. Now we are assessing the compound in a larger clinical trial including adult and pediatric subjects."

In the US it is estimated that 6-12 million people, mainly children aged 3-12 years, are infested each year with head lice (Pediculushumanuscapitis). With the emergence of drug resistant lice and poor efficacy of existing products, this under-served market represents a substantial commercial opportunity.

The trial is expected to be completed by the end of 2011.

About DeOvo

Despite its prevalence and high cost to the community, there have been few major advances in controlling head lice infestation in recent years. Most pediculicide products have little ovicidal activity and require two treatments (approximately 7 days apart), with the second application designed to treat those lice which have hatched from eggs that survive the first treatment. Non-compliance with this regimen and the difficulty in choosing the optimal time for the second application, are major difficulties in using these products. Hatchtech's DeOvo, a topical formulation of a known metalloprotease inhibitor, has shown both ovicidal and lousicidal activity and offers the potential for a more effective treatment following a single

application.

About Pediculosis

It is estimated that 6-12 million people, in the United States, mainly children aged 3-12, are infested each year with head lice (Pediculushumanuscapitis). The direct cost of treatment is estimated at several hundreds of millions of dollars. Added to this direct economic burden are the indirect costs including missed days from school, lost work productivity by parents who stay home to treat their children and costs borne by the school itself in trying to control or prevent this problem. The total costs have been estimated to be 1billion USD in the US alone.
