Ligand Announces Positive Preclinical Data for Glucagon Program in Model of
Type 1 Diabetes
Data Presented at American Diabetes Association 73^rd Scientific Sessions
SAN DIEGO -- June 24, 2013
Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) announced the presentation
of a poster titled “Glucagon Receptor Antagonist LGD-6972 Is Efficacious in
Streptozotocin-Induced Diabetic Mice” at the 73^rd Scientific Sessions of the
American Diabetes Association in Chicago. The poster provides data from
preclinical studies of Ligand’s novel compound, LGD-6972, demonstrating
significant glucose lowering activity in an animal model of type 1 diabetes.
Highlights of the presentation include:
*LGD-6972 is a potent and selective antagonist of the glucagon receptor
(GCGR) that has previously demonstrated activity in pre-clinical models of
type 2 diabetes.
*LGD-6972 significantly lowered fasting and non-fasting glucose levels in a
mouse model of type 1 diabetes.
*LGD-6972 reduced HbA1c, ketone bodies, and free fatty acids in diabetic
*LGD-6972 had additive effects when used in combination with insulin
therapy and may be useful in an insulin sparing regimen.
“Glucagon receptor antagonism could play an important role in the treatment of
diabetes. Previous studies have demonstrated efficacy in models of type 2
diabetes and the present work shows utility for type 1 diabetes as well,”
commented Matthew W. Foehr, Executive Vice President and Chief Operating
Officer of Ligand. “Our glucagon program is an important example of the
diversity of partnered and unpartnered products making up Ligand’s extensive
portfolio of assets. We plan to submit an IND for LGD-6972 in the second half
About Ligand’s Glucagon Receptor Antagonist Program
Glucagon is a hormone produced by the pancreas that stimulates the liver to
produce glucose (sugar). Overproduction of glucose by the liver is an
important cause of high glucose levels in patients with type 2 diabetes and is
believed to be due in part to inappropriately elevated levels of glucagon.
High glucose levels can cause diabetic complications such as blindness and
kidney disease. Glucagon receptor antagonists are designed to lower glucose
levels by reducing the production of glucose by the liver. Glucagon receptor
antagonists are novel molecules that have demonstrated a reduction of glucose
and hemoglobin A1c in mid-stage clinical trials.
