BIOALLIANCE PHARMA

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, said today it will present the first promising in vivo results for its New Entity AMEP, invasive melanoma drug candidate (BA 015 program), at the 15th congress of the European Society of Gene and Cell Therapy, Rotterdam, October 27-30.

These research results complement BioAlliance Pharma’s activities in innovative drug delivery methods, which have enabled it to bring a product to market, and carry out clinical programs including three ongoing Phase III trials, while pursuing basic research into new therapeutic targets in HIV and cancer.

The latest results are in the field of oncology where the company has focused on new targets, particularly those implicated in resistance and tumoral invasion (cytoskeleton). The development of AMEP is part of this strategy. AMEP is an anti-angiogenic and anti-proliferative peptide, which binds to the integrins of activated endothelial and cancerous cells.

The Company has developed a plasmid that allows the expression of AMEP in vivo. It will give data on its properties and its anti-tumoral efficacy at the ESGCT congress. AMEP or plasmid AMEP (BA 015 program) is a BioAlliance Pharma drug candidate with potential use against invasive melanoma.

BioAlliance Pharma is collaborating closely with international experts in angiogenesis and oncology at Inserm (Saint Louis Hospital) and the Institut Gustave Roussy. “BioAlliance’s work with Inserm and the IGR is an excellent example of the company’s academic alliances’ with the major French research laboratories focusing on human health,” said Professor Christian Auclair, CSO at BioAlliance Pharma. “These alliances give the company continued access to cutting edge science.”

Two patent families protect this program internationally as part of BioAlliance Pharma’s vigorous intellectual property policy.
