Thallion Pharmaceuticals and LFB Biotechnologies Sign Definitive Agreement to Develop and Commercialize Treatment for E. Coli (STEC) Infection

LES ULIS, FRANCE and MONTREAL, QUEBEC--(Marketwire - Feb. 16, 2010) - Thallion Pharmaceuticals Inc. ("Thallion") (TSX:TLN) and LFB Biotechnologies ("LFB") today announced the signing of a definitive development and commercialization agreement for Shigamabs®, Thallion's product candidate for the treatment of Shiga toxin-producing E. coli, or STEC, infections. Thallion has granted LFB, an affiliate of the Laboratoire francais du Fractionnement et des Biotechnologies of Les Ulis, France, an exclusive license for the commercial rights to Shigamabs® in Europe, South America and other territories of strategic interest to LFB, including Russia, Turkey, China, South Korea and Northern African countries. Thallion retains commercial rights for the rest of world, including North America. The agreement follows the binding Letter of Intent signed in December 2009 between the two parties.

"This transaction transforms our company into a focused Shigamabs® play with a strong and stable balance sheet and a quality partner with extensive experience in both the development of monoclonal antibodies and the commercialization of hospital-based products that treat rare diseases," said Dr. Allan Mandelzys, Chief Executive Officer of Thallion. "The collaborative nature of this agreement establishes joint committees comprising members from both organizations that will oversee the development and commercialization of Shigamabs®. Together, we plan to put Shigamabs® back in the clinic and initiate a Phase II study in South America during the second half of this year."

"LFB shares Thallion's vision of developing new treatments for under-served markets," stated Christian Bechon, LFB's Chairman & CEO. "Shigamabs® is particularly well suited to broadening LFB's portfolio of monoclonal antibodies and, as an Orphan Drug, perfectly fits with our commitment in rare and severe diseases. We look forward to moving Shigamabs® into the Phase II clinical trial."

Pursuant to the agreement, Thallion is eligible to receive payments of up to 95 million euros (approximately C$150 million) from LFB, which includes an up-front licensing fee of 1.5 million euros (approximately C$2.3 million), funding for substantially all future clinical development costs, as well as milestone payments associated with the development, approval and commercial sales of Shigamabs®. In addition, Thallion is eligible to receive tiered, double digit royalties based on product sales in all the LFB territories. Thallion will retain primary responsibility for the conduct of the clinical program, whereas LFB will be responsible for the exclusive global manufacturing and supply of Shigamabs® for both clinical study and commercial sales.

Thallion and LFB anticipate promptly submitting an amended protocol to selected South American regulatory agencies, based on a clinical protocol that had been approved previously by both the Argentinean and Chilean authorities. The companies intend to immediately initiate activities preparing for the launch of a Phase II study in South America in the second half of 2010, coinciding with the start of the high incidence season for STEC infection in the Southern hemisphere.

About Shigamabs®

Shigamabs® consists of two monoclonal antibodies designed to bind specifically and exclusively to the Shigatoxin 1 and Shigatoxin 2 toxins secreted by Shiga-toxin E. coli (STEC) bacteria. STEC infections are primarily foodborne bacterial infections that cause serious health complications, particularly in young children and the elderly, and affect approximately 314,000 people annually in the industrialized world. There are no approved products available for the treatment of STEC infections. The Shigamabs® antibodies, administered as a single intravenous injection, bind to their respective toxin and neutralize them by forming a complex that is absorbed and destroyed by the liver and spleen. The dual antibody approach enables Shigamabs® to address STEC infections caused by E. coli secreting either Shigatoxin 1, Shigatoxin 2 or both Shigatoxins. Shigamabs® has obtained orphan drug designation both in the US and in Europe.

Thallion has completed multiple preclinical studies and four Phase I clinical trials evaluating the efficacy and safety of Shigamabs®. The clinical trials demonstrated that Shigamabs® are safe and well tolerated when administered both individually and in combination at various dose levels. No serious adverse events were experienced in any of the 50 healthy volunteers that have received the drug. In preclinical studies Shigamabs® demonstrated a significant protective effect at relatively low doses, and animal rescue was possible even when the drug was administered 72 hours post-infection.
