 Forward Looking Statements
This presentation contains, in addition to historical information,
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995. These statements relate to future events or
future financial performance, and use words such as “may,”
“estimate,”
“could,”
“expect”
and others. They are based on our current expectations
and are subject to factors and uncertainties which could cause actual results to
differ materially from those described in the statements. Factors that could
cause our actual performance to differ materially from those discussed in
the forward-looking statements include, among others: incurrence of
operating losses since our inception, uncertainty as to adequate financing
of our operations, extensive and costly regulatory oversight that could
restrict or prevent product commercialization, inability to achieve commercial
product acceptance, inability to protect our intellectual property,
dependence on strategic partnerships, product competition, and others stated
in risk factors contained in our SEC filings. We cannot assure that we have
identified all risks or that others may emerge which we do not anticipate.
You should not place undue reliance on forward-looking statements.
Although subsequent events may cause our views to change, we disclaim any
obligation to update forward-looking statements.

 Galectin-3 Is A Critical Target For
Therapy of Liver Fibrosis
1.
Galectin-3 is produced in large amounts by human fibrotic liver.
2.
Galectin-3 is essential in mice for the development of liver fibrosis.
Fibrosis due to toxin exposure or fatty liver does not occur in mice
that lack the galectin-3 gene.
3.
Galectin inhibitors block production of fibrogenic markers in the key
human cell (stellate cells) responsible for liver fibrosis.
4.
Galectin inhibitors reverse experimental fibrosis in rats induced by
both fibrosis and fatty liver.

 Development Program & Markets
•
Pursue two indications for human proof of concept
•
NASH
•
Post-Transplant Hepatitis C Fibrosis
•
NASH
•
NIH estimates 5% of US population has NASH
•
Projected to become the number one reason for liver transplant
•
Multiple candidates in development but none have multiple sites of action,
effect on fibrosis, or safety profile
•
Post-Transplant Hepatitis C Fibrosis
•
Much smaller population but high unmet medical need
•
Orphan disease status possible
•
Expansion to other indications is possible
•
Other liver diseases such as hepatitis and alcoholic disease
•
Pulmonary, renal, and heart fibrosis

5- FU/GM-CT-01 than in comparison to other studies using

 Development Approach In
Colorectal Cancer
•
Studies demonstrate potential utility of galectin inhibitors in
combination with chemotherapy in cancer
•
FDA has confirmed that preclinical and clinical data are
adequate to proceed with large clinical trials
•
We are deferring new clinical trials pending data from the tumor
immunology clinical trial that may improve the design of future
studies
•
More rapid international registration is an approach that may
provide revenue to support development programs and gain
additional clinical experience with GM-CT-01

However, these T-cells lose the ability to kill
tumor cells. A key reason is that Galectin-3
secreted by tumors bind to T-cells and turn off
their ability to kill tumor cells
