Thallion Pharmaceuticals Inc. (TSX VENTURE:TLN) ("Thallion") and LFB
Biotechnologies ("LFB") today announced that they have reached an agreement on
the termination of their Development and Licensing Agreement related to
Thallion's Shigamabs(R) program. All rights to the program will revert back to
Thallion including all data, materials and know-how developed by and for LFB
during the collaboration. LFB will cease to have any rights to the Shigamabs(R)
program and all future quarterly payments due to Thallion by LFB in support of
Shigamabs(R) development will terminate. LFB will pay for all outstanding and
accrued costs related to product manufacturing and Thallion will be responsible
for all remaining costs associated with the completion of the SHIGATEC Phase II
clinical study. 


"Thallion has been an excellent partner in this program and Shigamabs(R) could
be an important product for alleviating the suffering of the thousands of
patients infected by STEC each year," said Guillaume Bologna, executive VP of
LFB Biotechnologies for development & business development. "Despite our strong
collaboration, an internal pipeline prioritization necessitated a reallocation
of our resources. We wish Thallion much success in the future."


"While we are disappointed with the early termination of the LFB collaboration,
we understand LFB's decision to reprioritize their product portfolio in these
challenging economic times. We thank our LFB colleagues for their valuable
contributions to the advancement of the Shigamabs(R) clinical program," said Dr.
Allan Mandelzys, CEO of Thallion. We will now focus on completing the long term
safety evaluation of our patients and close out the SHIGATEC trial in the second
quarter, while initiating efforts towards securing a new development partner for
this asset."


About Shigamabs(R)

Shigamabs(R) consists of two monoclonal antibodies designed to bind specifically
and exclusively to the Shiga toxin 1 and Shiga toxin 2 toxins secreted by Shiga
toxin- producing E. coli 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(R) antibodies, administered as a
single intravenous infusion, 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(R) to address STEC infections caused by
E. coli secreting either Shiga toxin 1, Shiga toxin 2 or both Shiga toxins.
Shigamabs(R) has obtained orphan drug designation both in the U.S. and in Europe
