Zila's OraTest(TM) Oral Cancer Detection System Approved In Several European Union Nations

PHOENIX, April 13 /PRNewswire/ -- Zila, Inc. (Nasdaq: ZILA - news), international provider of healthcare products for dental/medical professionals and consumers, announced that its oral cancer detection system, OraTest(TM), has won regulatory approval in Portugal, Belgium, Luxembourg, Holland, Finland and Greece. The approvals were granted Thursday under European Union drug approval rules, based upon the United Kingdom's [NYSE:UKM - news] approval of OraTest in 1995. Applications are pending in the remainder of the EU member nations.

Zila President Joseph Hines said, ``The potential EU market for OraTest is greater than that of the United States, owing to the EU's larger population and higher smoking rates. (Tobacco use and heavy drinking are the primary causes of oral cancer.) We look forward to OraTest saving lives throughout the world.''

Zila's British licensee, Stafford-Miller Ltd. (a division of Block Drug Company), will launch an intensive marketing campaign for OraTest (known in the UK as OraScreen(TM)) on April 24, targeting dentists in general practice throughout the UK. Stafford-Miller has been working with UK dental specialists for two years, laying the groundwork for the upcoming mass marketing effort.

OraTest is a patented five-minute mouthrinse sequence that has been shown to be 100 percent sensitive for squamous cell carcinoma (oral cancer). European nations have approved its use for screening, detection of second primary lesions, and defining margins of lesions for biopsy and surgery. OraTest is also available in Australia, Canada, Taiwan, Hungary, Bermuda, Barbados and the Bahamas. FDA approval is pending.
