Forward Looking Statements
This presentation contains, in addition to historical information, statements that look forward in time or that express management’s beliefs, expectations or hopes. Such statements are 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 risks and uncertainties that could cause actual results to differ materially from those described in the statements. These statements include our plans, expectations and goals regarding drugs in development, clinical trials and regulatory approval for any of our drugs or treatments, the anticipated timeline for clinical trials and results, related market opportunities for our drugs, potential benefits of our drugs, efforts related to partnering opportunities with other companies, estimates regarding cash and spending, liquidity and funding requirements for clinical trials, and estimates regarding those impacted by NASH, liver fibrosis and cirrhosis. The risks and uncertainties impacting these statements include that our plans, expectations and goals regarding drugs in development, clinical trials and regulatory approval are subject to factors beyond our control. Our clinical trials may not begin or produce positive results in a timely fashion, if at all, and any necessary changes during the course of such trials could prove time consuming and costly. We may have difficulty in enrolling candidates for testing and we may not be able to achieve the desired results. Upon receipt of regulatory approval for any drug or treatment, we may face competition with other drugs and treatments that are currently approved or those that are currently in development, which could have an adverse impact on our ability to achieve revenues from the approved indication. Plans regarding development, approval and marketing of any of our drugs are subject to change at any time based on the changing needs of our company as determined by management and regulatory agencies.
Estimates regarding the potential benefits of our drugs and the potential market for any of our drugs may be inaccurate and, to the extent the estimates are correct, we may not be successful in achieving revenues from any such drugs, as the successful marketing of any approved drugs will be subject to strong competition within the health care industry and patient and physician acceptance of our drugs as safe, affordable and effective. Our ongoing discussions with other companies may not lead to partnering opportunities, and if we are unable to partner with other companies and/or raise additional capital, we will likely be unable to complete future stages of clinical trials and ultimately produce revenue from our drugs in development. Funding from potential sources of capital, including the potential exercise of warrants, may not materialize. To date, we have incurred operating losses since our inception, and our ability to successfully develop and market drugs may be impacted by our ability to manage costs and finance our continuing operations. For a discussion of additional factors impacting our business, see our most recent Annual Report on Form 10-K and our subsequent filings with the SEC. 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.

Galectins Inhibitors
Galectin family (15 members) are classified by structure and the number of carbohydrate binding domains (CRD).
Galectins bind via their CRD to oligosaccharides containing terminal galactose residues on macromolecules such as glycoproteins.
Function through binding glycoproteins on cell surface and extracellular space to modulate cellular and immune system function.
Galectin-3 is widely expressed, but highest in immune cells (macrophages)
Under normal physiological situations, galectin-3 is expressed at low levels In areas of acute or chronic inflammation and fibrogenesis, the gal-3 expression is markedly increased. The majority of cancers express high levels of galectin-3
Our proprietary drugs are complex carbohydrates with galactose residues that bind galectin proteins (galectin-3 > galectin-1)

Fundamental Science on Target is Strong: Galectin-3 is critically important in the development of organ fibrosis
Galectin-3 null mice (no galectin-3) are resistant to fibrosis due to toxin-induced liver toxicity
Red stain is collagen, the principal component of fibrotic tissue
Mice treated with liver toxin to induce fibrosis
Normal mouse
No gal-3 mouse
Normal mice develop fibrosis whereas those without gal-3 do not
Henderson, et al 2006
Galectin-3 null mice are also resistant to fibrosis in:
Fatty liver disease Kidney fibrotic disease Lung fibrotic disease

Liver Fibrosis Development Program
NASH (Non-Alcoholic SteatoHepatitis)
Multiple liver diseases lead to fibrosis
End stage fibrosis, or cirrhosis, leads to liver failure, medical complications, and death Only current therapy is liver transplant
There is no approved medical therapy for liver fibrosis Very large unmet medical need
First indication is fatty liver disease with fibrosis (non-alcoholic steatohepatitis, or NASH).
Prevalence of NASH in U.S. is between 9-15 million people Over 25% will develop cirrhosis; estimated prevalence of patients with advanced fibrosis is 6 million.
NASH cirrhosis projected to be primary reason for liver transplant

NASH with Fibrosis Development Program: Accomplishments
New strategic focus: 2011 Annual Stockholder Meeting NASH indication chosen based on pre-clinical experiments Multiple studies in animal models confirmed robust effect on inhibition and regression of fibrosis, as well as reduction in inflammation and cell death in the liver.
GR-MD-02 more effective than GM-CT-01
GMP drug substance and product produced by CMO
Studies completed in multiple species elucidating pharmacology, pharmacokinetics, and toxicology.
FDA review of IND for GR-MD-02 submitted Jan. 30, 2013 concluded that we may proceed with human clinical studies. Fast Tract Designation received in August 2013 Phase 1 trial: First cohort enrollment completed. Data to be reported around end of first quarter 2014.

Competition in NASH
Most drugs in development focus on improving NASH activity score (fat, inflammation, and cell death) at a stage of the disease when there are minimal amounts of fibrosis.

Cancer immunotherapy drugs will soon be a$35 bn global industry
May 22, 2013
“We believe this market will generate sales of up to $35 billion (a year) over the next 10 years and be used in some way in the management of up to 60 percent of all cancers,” Citi analyst Andrew Baum said on Wednesday.

Cancer Therapy Strategy
Focus on cancer immunotherapy based on the hypothesis that galectin inhibitors will enhance efficacy of immunotherapies
Metastatic melanoma is initial cancer indication
In US 76,000 new diagnoses and 9,100 deaths annually
5% five year survival for metastatic disease
Even with newly approved drugs, still a substantial unmet medical need
We have sought collaborations with institutions that have:
Demonstrated clinical trial expertise in melanoma
Tumor immunology basic science research
Ability to conduct clinical trials and assist in funding
Two collaborations have been established

Exploratory Clinical Trial at Ludwig Institute in Brussels Belgium
Metastatic melanoma trial, funded by Ludwig Institute, was initiated in 2011
Design was to prime patients for treatment with a melanoma specific peptide vaccine and then treat with GM-CT-01
Eight patients screened, 6 patients enrolled, and 3 patients reached treatment with GM-CT-01 and completed the protocol
No treatment emergent AE’s

Enrollment in the study has been suspended
Introduction of Yervoy ® and Zelboraf ® has markedly reduced/eliminated the ability to recruit patients
The Ludwig Institute does not currently have plans for regulatory approval of its peptide vaccine

29NASDAQ:GALT
Pre-clinical studies show galectin inhibitors enhance immune response
Collaboration established in 2012 with Earle A. Chiles Research Institute (EACRI)
Pre-clinical results demonstrate that treatment with GR-MD-02 enhances antigen-specific CD8+ T-cell response and augmentation of memory CD8+ T-cells in non-tumor mice
In tumor bearing animals, the combination of checkpoint inhibitors (anti-CTLA4 and anti-PD1) with GR-MD-02 enhances CD8+ and CD4+ T-cell proliferation, reduces tumor size, and enhances survival in multiple mouse cancer models
Important to note that GM-CT-01 did not have an effect
These results have led to decision to initiate a clinical trial combining Yervoy with GR-MD-02
