About BioAlliance Pharma

BioAlliance Pharma SA (Euronext Paris: BIO) is a specialty pharmaceutical company focused on the development and marketing of innovative therapeutics targeting drug resistance in cancer, HIV, and opportunistic infections.

Specialty pharma targets the development and marketing of drugs for specialist markets and selected populations. This business model, unlike that of “big pharma” which targets general medicine, offers faster product development, lower R&D costs, smaller sales teams, and hence higher margins and fast growth.

The Company is developing three broad product ranges based on the Lauriad® mucoadhesive technology which allows an early and prolonged release of therapeutic agents at the site of the disease, the Transdrug® nanoparticle technology designed specifically for intracellular targeting, and a New Chemical Entities program focused on development of new drugs in oncology and HIV.

The Loramyc® (miconazole Lauriad®) 50 mg Mucoadhesive Buccal Tablet has completed two Phase III clinical trials in Europe for treatment of oropharyngeal candidiasis (OPC) in cancer and HIV patients. In October 2006, the company obtained Marketing Authorization for this product in France. A pivotal Phase III trial of Loramyc® is ongoing in the US for the same indication. The company has submitted a Phase III protocol for a second product, acyclovir Lauriad®, an oral herpes treatment. Approval was granted in Australia, France and the Czech Republic in February 2007. A Phase II/III trial in primary liver cancer (hepatocellular carcinoma or HCC) utilizing the Company's doxorubicin Transdrug® nanoparticle delivery technology started in Europe in December 2006. This product has been granted orphan drug status by the EMEA and the FDA.
