Sosei Announces Successful Completion of Phase I Study for SO-1105 for the Treatment of Oropharyngeal Candidiasis

TOKYO, July 2, 2012 /PRNewswire/ --

Sosei Group Corporation ("Sosei"; TSE Mothers Index: 4565), the biopharmaceutical company, today announces that its wholly owned Japanese subsidiary, Sosei Co., Ltd., has successfully completed a Japanese Phase I trial for SO-1105 for the treatment of oropharyngeal candidiasis. SO-1105 was originally developed by a French pharmaceutical company, BioAlliance Pharma, which received its first marketing authorization for SO-1105 in France in October 2006. SO-1105 has since been registered in 26 European countries, in South Korea, and in the United States, under the trade names Loramyc®/Oravig®.

The clinical study was conducted in a single study centre in Japan, and was designed to evaluate the pharmacokinetics and safety of SO-1105 in healthy Japanese adults.

SO-1105, a once daily muco-adhesive buccal tablet containing 50 mg of miconazole administered to the buccal mucosa in 12 healthy volunteers provided a 24-hours sustained high concentration in saliva and on the infection site (upper surface of the tongue). In addition, low plasma concentration indicates that no serious systemic adverse events can be expected. Results from the Phase I study also showed that SO-1105 had a good overall safety profile, and that usability and compliance were good.

SO-1105 has the potential to become the first long-acting, sustained-release treatment in tablet form for oropharyngeal candidiasis in Japan that could enhance patients' compliance and quality of life.

Shinichi Tamura, CEO of Sosei Group Corporation, commented: "This is an important step forward in development of SO-1105. We will continue our efforts to bring this widely used drug to the Japanese market as quickly as possible."

About Oropharyngeal Candidiasis

Fungal infections of the oral mucosa are most frequently caused by Candida species, with C. albicans being the most common species associated with such infections. Oropharyngeal candidiasis is commonly found in immuno-compromised patients, including HIV and cancer patients, and in other chronic disease states such as diabetes. For instance, oropharyngeal candidiasis is the most frequently occurring infection in head and neck cancer patients undergoing radiation therapy. The clinical presentation of oropharyngeal candidiasis is variable with symptoms including soreness, burning, and/or altered taste. The signs of clinical candidiasis usually include white pseudomembraneous plaques and patches (thrush), erythematous lesions or occasionally angular cheilitis. Left untreated, the condition may progress to involve the esophagus or to more serious systemic complications.
