BIOALLIANCE PHARMA

Paris, September 25, 2007 – BioAlliance Pharma SA (Euronext Paris - Code Isin: FR0010095596 -BIO), a specialty pharmaceutical company focused on the development and marketing of innovative therapeutics targeting cancer, HIV, opportunistic infections and drug resistance, presented new data today at the 14th European Cancer Conference (ECCO 2007 - Barcelona, Spain; September 23 – 27) that confirm the efficacy of BioAlliance Pharma’s antifungal,
particularly in populations with poor prognostic factors of response.

New results from tests adjusted for risk factors showed a strong trend toward superiority in favor of miconazole Lauriad®, in particular in patients with impaired saliva secretion or extended lesions.

BioAlliance Pharma carried out an international multicenter randomized Phase III trial in accordance with French Drug Agency recommendations, in 282 head and neck cancer patients previously treated with radiotherapy or chemotherapy and suffering from oropharyngeal candidiasis. The aim was to demonstrate that the miconazole 50mg mucoadhesive buccal tablet (miconazole Lauriad®) once daily was not inferior to miconazole 500mg oral gel four times per day.

Even with a risk factor imbalance weighted against miconazole Lauriad®, results from these tests confirmed that the success rate after 14 days of treatment with miconazole Lauriad® (50mg) administered once daily was not-inferior to that of miconazole 500mg oral gel administered four times per day. A difference of 7.1 % was observed in favor of the miconazole Lauriad® group.

After researchers made adjustments for the risk factors related to the extent of mucous lesions and saliva secretion, the new results clearly establish the breakthrough due to delivery of BioAlliance Pharma miconazole Lauriad® at the infection site. The success rate at 14 days in patients suffering from multiple lesions is 58.7 percent for the miconazole Lauriad® group versus 37.5 percent with the gel. This efficacy is obtained with 10-fold lower doses of active principle administered just once a day.

These data suggest that miconazole Lauriad® can be used as first line therapy in cancer patients with oropharyngeal candidiasis, in line with international experts’ recommendations to treat initial episodes of oropharyngeal candidiasis with topical treatments.
