Zila Receives Indefinite OraTest Marketing Authorization in Seven European Countries

Zila, Inc. (NASDAQ:ZILAD) today announced that the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) has issued an indefinite renewal of the marketing authorization for OraTest(R), the company's proprietary oral cancer diagnostic kit. Under the European Union's (EU) mutual recognition process, the company expects to receive renewal licenses for member states including Finland, Greece, Luxembourg, The Netherlands, Belgium, the U.K. and Portugal, over the next 30 to 60 days. The combined population of these seven countries exceeds 100 million. The company is seeking marketing partners in the seven EU countries.

OraTest is indicated as an adjunct to visual examination in patients considered at high risk for having high-grade premalignancies or malignant lesions. The product can also be used to monitor patients with previously treated oral squamous cell carcinoma for recurrent disease. The kit contains Zila's patented, pharmaceutical grade tolonium chloride rinse product.

"Adding OraTest to our international product portfolio provides the opportunity to expand the potential market for our oral cancer screening and testing product franchise," said David Bethune, Zila's chairman and chief executive officer. "The OraTest diagnostic kit and ViziLite(R) Plus, our proprietary oral cancer screening technology, are complementary products with distinct indications, which will allow us to market to a more diverse group of healthcare professionals within the EU."

Pursuing regulatory approval in additional EU countries is under evaluation. Since the initial approvals of OraTest in the EU, Zila has compiled additional evidence-based data in support of approval.

Zila's proprietary oral cancer screening technology, ViziLite Plus, utilizes a chemiluminescent light source (ViziLite) and the patented vital tissue dye TBlue(R), helps dental professionals identify and evaluate abnormalities in the mouth that could potentially harbor pathologic changes. ViziLite Plus is for use in a population at increased risk for oral cancer.

About Oral Cancer and OraTest

Oral cancer is the sixth leading cause of cancer worldwide, and in the U.S., one person dies every hour from the disease. According to American Cancer Society data, nearly as many women will be diagnosed with oral cancer as with cervical cancer this year. The key to reducing the impact of this disease is early detection. Some worldwide clinical trials have demonstrated that the conventional visual/tactile examination may fail to identify up to 40% of cancers and precancers.

 Oral Cancer Risk factors: -- age - adults (particularly those age 40 and over) -- tobacco use - particularly if combined with heavy alcohol consumption -- heavy alcohol consumption -- excessive sun exposure to the lips -- sexually transmitted human papillomavirus (HPV)
