Paris, April 15, 2013 – BioAlliance Pharma SA today announced the receipt of marketing authorization from the U.S. Food and Drug Administration (FDA) for Sitavig in the treatment of recurring Herpes labialis, marking the successful conclusion to the assessment procedure carried out by the American authorities.

After Loramyc®, registered in 26 countries including the United States, BioAlliance Pharma for the second time has successfully passed the FDA review. The registration of Sitavig, developed internally, shows once again the teams’ capacity and expertise.

Based on proprietary Lauriad® technology, Sitavig comes in the form of a mucoadhesive tablet

acylovir

which the patient places on the gum and which delivers a high concentration of acyclovir directly to the lip, the site of the cold sore infection. In a phase III international study conducted on 775 patients, Sitavig demonstrated a high level of efficacy in terms of healing time with one single tablet containing 50 mg of acyclovir and an excellent tolerance profile. In addition to its efficacy, Sitavig offers a unique unobtrusive and simple formulation with a single application for the episode’s entire duration, representing major advantages for patients suffering from recurrent herpes sores.

“Herpes labialis is an infection that affects a very large number of patients around the world and for which there is a real need for effective treatment with appropriate presentation. We participated in the phase III clinical trial in our center and were able to test the benefits of Sitavig. We are very pleased with the outcome of this development which will allow patients, once the product is on the market, to have a drug that meets their needs,” says Professor Stephen Keith Tyring of the Dermatology Department at the University of Texas Health Sciences Center in Houston.

Herpes labialis is an extremely widespread condition. Its estimated annual prevalence is 15% of the adult population¹, namely some 40 million people in the United States with more than 100 million episodes of Herpes labialis annually, representing a significant potential market of hundreds of millions of dollars.

Sitavig, the second drug of BioAlliance’s ‘Specialty Products’ portfolio, is intended to be marketed via international partnership agreements and to generate significant income for the company. Obtaining the MA will allow the company to accelerate discussions with potential partners for marketing in the United States.
