Treatment with Novel Thyroid Receptor Beta Agonist Led to Significant Reductions in Liver Triglyceride Levels and Liver Weight Compared to Controls
SAN DIEGO, Feb. 9, 2017 /PRNewswire/ -- Viking Therapeutics, Inc. ("Viking"
(NASDAQ: VKTX), a clinical-stage biopharmaceutical company focused on the development of novel therapies for metabolic and endocrine disorders, today announced positive initial results from a proof-of-concept study of VK2809 in an in vivo model of glycogen storage disease Ia (GSD Ia). GSD Ia is a rare, orphan genetic disease that results in excess accumulation of glycogen and lipids in liver tissue. Data to date showed that treatment with VK2809 produced rapid and substantial reductions in liver triglyceride content, liver weight and liver weight as a percentage of body weight compared with vehicle-treated controls. Complete results from the ongoing study, which is being conducted under a sponsored research agreement between Duke University and Viking, will be presented at an upcoming scientific meeting.
Data demonstrated that treatment with VK2809 led to statistically significant reductions in key metabolic markers of GSD Ia. Mean liver triglyceride content was reduced by more than 60% in VK2809-treated animals relative to vehicle-treated control animals, while average liver weight was reduced by more than 30% vs. controls. Importantly, average liver weight as a percent of total body weight also declined by approximately 20% in treated vs. control animals. The study will continue to evaluate the impact of VK2809 on these and other disease markers.
GSD Ia is characterized by an inability to metabolize glucose precursors, resulting in hypoglycemia and increased lipogenesis. The disease is caused by mutations in the gene for glucose-6-phosphatase (G6PC), a critical enzyme involved in the production of glucose from either glycogen or gluconeogenesis. Impaired G6PC function leads to dramatically elevated liver triglyceride levels in human patients and in animal models of the disease. In patients, this may contribute to serious long-term complications, such as severe hepatomegaly, hepatic adenomas, and hepatocellular carcinoma. Manifestations of the disease begin to appear shortly after birth and continue through adolescence into adulthood. There is currently no approved therapy for GSD Ia. VK2809's potential to rapidly reduce hepatic triglyceride levels, as demonstrated in this initial evaluation in a GSD Ia model, provide support for the continued investigation of the compound in this indication.
"These initial proof-of-concept data showing VK2809's activity in this model of GSD Ia are very encouraging. Due to its unique liver-targeted activity, we believe that VK2809 has a therapeutic profile that may align well with the treatment goal of reducing triglycerides, steatosis, and mitigating the metabolic complications of GSD Ia," said Brian Lian, Ph.D., chief executive officer of Viking. "GSD Ia is a rare metabolic disease for which there are no approved therapeutics. These patients suffer from a range of serious consequences, including an increased risk of liver bleeding, transplant, or cancer. Our work in this area represents a strategic and complementary addition to our ongoing VK2809 development program, which currently includes a Phase 2 clinical trial in patients with hypercholesterolemia and non-alcoholic fatty liver disease."
The ongoing proof-of-concept study is designed to evaluate the effects of VK2809 in Duke University's G6PC knockout mouse model, which replicates many of the same biochemical and physiological characteristics present in GSD Ia patients. Study mice are receiving VK2809 or vehicle once-daily and subsequently evaluated for changes in various measures of disease, including liver size, weight, and triglyceride content. Additional effects on glycogen and genetic markers are also being explored. Importantly, the preliminary results on hepatic markers are consistent with prior studies demonstrating VK2809's ability to potently reduce liver fat in other models of hepatic steatosis.
"The preliminary findings suggesting the potential triglyceride-lowering activity of VK2809 in GSD Ia are encouraging, particularly when demonstrated in the most studied GSD Ia animal model," said Dwight Koeberl, M.D., Ph.D., Professor of Medicine, Duke University School of Medicine. "We look forward to continuing the evaluation of VK2809 in GSD Ia."
VK2809 is a novel, orally available small molecule thyroid receptor beta (TR) agonist that possesses selectivity for liver tissue, as well as the beta receptor subtype, suggesting promising therapeutic potential in a range of lipid disorders. Viking is currently evaluating VK2809 in a randomized, double-blind, placebo-controlled, parallel group Phase 2 study designed to assess the drug candidate's efficacy, safety and tolerability in approximately 80 patients with elevated LDL-C and non-alcoholic fatty liver disease. Previously reported clinical data have demonstrated that treatment with VK2809 leads to significant reductions in plasma triglycerides, LDL cholesterol (LDL-C), and atherogenic protein levels in subjects with mild hypercholesterolemia.
About GSD Ia
Glycogen storage disease Ia (GSD Ia) is a rare, orphan genetic disease caused by a deficiency of glucose-6-phosphatase (G6P), an enzyme responsible for the liver's production of free glucose from glycogen and gluconeogenesis. The disease, for which there is no approved treatment, results in an excess accumulation of glycogen and lipids in the liver, potentially leading to hepatosteatosis, liver failure, development of hepatic adenomas, and hepatocellular carcinoma. Increased triglyceride production and elevated hepatic triglyceride levels are characteristic of GSD Ia and associated with many manifestations of the disease. GSD Ia is estimated to occur in approximately 1 in every 50,000 -- 100,000 births in the United States. As manifestations of the disease begin to present themselves at birth, a sizeable portion of GSD Ia patients are children.
