  Announces Anti-Galectin Drug is Effective in Preclinical Studies

NORCROSS, Ga. -- January 22, 2013

Galectin Therapeutics (NASDAQ: GALT), the leading developer of therapeutics
that target galectin proteins to treat fibrosis and cancer, today announced
new preclinical data on the efficacy of anti-galectin therapy on diabetic
kidney disease. Treatment of diabetic mice with GR-MD-02 was found to reverse
the primary kidney disease associated with diabetes, called diabetic
nephropathy, the leading cause of kidney failure, dialysis and kidney
transplant. GR-MD-02 is the Company’s lead galectin inhibitor in development
for the treatment of liver fibrosis, including non-alcoholic steatohepatitis
(NASH) liver disease.

“These data extend the potential therapeutic use of GR-MD-02 into diabetic
kidney disease, a progressive disorder resulting in kidney scarring and
ultimately kidney failure,” said Peter G. Traber, MD, President, Chief
Executive Officer and Chief Medical Officer, Galectin Therapeutics Inc. “These
findings show the broad potential of GR-MD-02 for treating organ fibrosis
which positions us to develop partnerships with companies focused on kidney
disease, while we continue our focus on development for the treatment of liver

In the preclinical study, diabetic mice developed histological findings
consistent with diabetic nephropathy, consisting of glomerular lesions in the
form of diffuse mesangial matrix accumulation and proliferation. The kidneys
of the diabetic mice also showed fibrosis evidenced by interstitial collagen
deposition. Treatment with GR-MD-02 reduced the mesangial matrix accumulation,
which suggests the drug suppressed the production and/or accumulation of
extracellular matrix components. Additionally, GR-MD-02 markedly reduced the
area of interstitial fibrosis. These results demonstrate the anti-fibrotic
efficacy of GR-MD-02 in the kidney and its therapeutic potential in diabetic
nephropathy as well as other chronic kidney diseases.

About Diabetic Kidney Disease

Diabetic Nephropathy is the leading cause of dialysis and kidney
transplantation. It is a progressive kidney disease caused by angiopathy of
capillaries in the kidney glomeruli. It is characterized pathologically as a
diffuse glomerulosclerosis which results in proteinuria, nephrotic syndrome,
progressive reduction in glomerular filtration rate, and results eventually in
kidney failure. Diabetic nephropathy is due to longstanding diabetes mellitus
and is the major indication for dialysis in many Western countries. While
control of serum glucose level and control of blood pressure are effective in
reducing the progression of diabetic nephropathy, renal failure remains a
major health problem. Accordingly,  there is a great need to provide therapies
that are efficacious in preventing, slowing the progression or reversing
diabetic nephropathy and kidney fibrosis.
