Hatchtech Completes Treatment Phase of 2b Clinical Trial of New-Generation Head Lice Treatment Deovo™

MELBOURNE, Australia, Aug. 31, 2011 /PRNewswire-Asia/ -- Pharmaceutical company Hatchtech Pty Ltd has completed treatment of subjects for its Phase 2b clinical study to confirm the efficacy of its novel head lice treatment DeOvo™.

This Phase 2b trial is evaluating the efficacy, safety and tolerability of two dose levels of a single application of DeOvo™ compared to vehicle. The trial consists of treating 132 healthy subjects with head lice infestation, 2 years of age and older, in two study centers in the United States.

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

Hatchtech Chairman Dr Paul Kelly commented: "We continue to be encouraged by Hatchtech's progress with its next generation head lice product DeOvo™ in line with our business objectives. The recruitment and treatment of subjects in this study has been achieved and we look forward to receiving results of the study later this year as planned."

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

    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 PediculosisIt is estimated that 6-12 million people, in the United States, mainly children aged 3-12, are infested each year with head lice (Pediculus humanus capitis). 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.
