Viking Therapeutics Announces Promising Top Line Results from In Vivo Study of VK2809 in Non-Alcoholic Steatohepatitis (NASH)
31 minutes ago - DJNF
Statistically Significant Reductions Observed in Fibrosis, Liver Collagen, Liver and Plasma Lipids, and NAS Following Eight Weeks of VK2809 Treatment
SAN DIEGO, June 6, 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 top line results from a study of VK2809 in an in vivo model of non-alcoholic steatohepatitis (NASH). Data from this study demonstrated improvements across several key measures relevant to the development and progression of NASH. Animals receiving VK2809 experienced statistically significant improvements in non-alcoholic fatty liver disease activity score (NAS), liver collagen content, and liver fibrosis relative to vehicle-treated controls. NAS is a composite measure of disease activity which is comprised of steatosis, ballooning and inflammation. These results represent the first evidence of a thyromimetic agent providing histologic benefits in a NASH model, including an improvement in fibrosis.
The study was designed to evaluate VK2809 dosed orally (10 mg/kg/day) for eight weeks in a mouse model of diet-induced NASH.(1) Control cohorts received either vehicle or active control (a metabolic-targeting agent currently in late-stage clinical development for NASH). Animals were biopsied prior to treatment to ensure disease characteristics consistent with the human form of disease, including the presence of fibrosis.
A summary of preliminary findings is highlighted below:
-- Liver triglyceride content was reduced by 70% compared to vehicle control
(p<0.0001), and="" by="" 56%="" compared="" to="" active="" control=""><0.0001)>
-- Liver cholesterol content was reduced by 65% compared to vehicle control
(p<0.0001) and="" by="" 58%="" compared="" to="" active="" control=""><0.0001)>
-- Liver fibrosis was reduced by 50% compared to vehicle control (p=0.01)
and by 21% compared to active control (p=0.3)
-- Liver collagen content was reduced by 60% compared to vehicle control
(p<0.005) and="" by="" 49%="" compared="" to="" active="" control="" (p="0.07)">
-- Liver hydroxyproline content was reduced by 46% compared to vehicle
control (p=0.01) and by 36% compared to active control (p=0.06)
Additional data showed that animals treated with VK2809 experienced a 40% mean improvement in NAS after eight weeks, compared to vehicle-treated controls (p<0.0001; average="" baseline="" nas="" 5.7;="" n="12/cohort);" and="" 50%="" of="" vk2809-treated="" animals="" demonstrated="" at="" least="" a="" two-point="" improvement="" in="" nas,="" compared="" with="" no="" vehicle-treated="" animals="" demonstrating="" at="" least="" a="" two-point="" improvement="" (p="0.01)." no="" animals="" treated="" with="" vk2809="" demonstrated="" a="" worsening="" in="" nas="" vs.="" approximately="" 60%="" of="" vehicle-treated="" animals="" demonstrating="" a="" worsening=""><0.0001). improvements="" in="" all="" subcomponents="" of="" nas="" (inflammation,="" ballooning,="" and="" steatosis)="" were="" observed="" in="" vk2809-treated="" animals="" relative="" to="" vehicle="" controls.="" consistent="" with="" previously-reported="" data,="" treatment="" with="" vk2809="" also="" produced="" significant="" reductions="" in="" plasma="" triglycerides="" and="" cholesterol="" in="" this="" study.="" in="" addition,="" vk2809="" demonstrated="" promising="" safety="" and="" tolerability.="" all="" animals="" received="" all="" scheduled="" doses="" of="" drug="" and="" there="" were="" no="" unexpected="" or="" abnormal="" laboratory="" findings.="">
"The preliminary data from VK2809 in this model of diet-induced NASH demonstrate promising results in the quantitative resolution of collagen, a major component of fibrosis, as well as significant improvements in intracellular fat content," stated Joel Lavine, MD, PhD, Chief of Pediatric Gastroenterology, Hepatology, and Nutrition at New York-Presbyterian/Morgan Stanley Children's Hospital. "These represent important elements of NASH and it will be interesting to see additional studies conducted with VK2809 in this setting."
"We are excited about the initial results from this study, as they demonstrate promising effects in a model of NASH that we believe reflects many characteristics of the disease in humans," said Brian Lian, Ph.D., chief executive officer of Viking. "The robust effect across multiple disease metrics, including reductions in collagen and lipotoxic lipids suggests potential benefits on endpoints important in NASH. The observed reductions in hepatic collagen content and fibrosis, by morphometric analysis, are particularly noteworthy, as these data represent the first quantitative histologic evidence that treatment with a thyromimetic agent can potentially improve NASH-related fibrosis. These results provide further support for the development of VK2809 in these settings."
Scientific literature suggests that liver fibrosis is associated with long-term outcomes in patients with non-alcoholic fatty liver disease and that hepatic collagen content is correlated with fibrosis staging and outcomes in these patients.(2,3,4) In addition, recently-published data have indicated that a reduction of de novo lipogenesis can produce improvements in markers of liver fibrosis in patients with NASH.(5) These data provide support for the potential benefits of VK2809 in NASH, as prior data have shown that VK2809 downregulates genes important for de novo lipogenesis, while simultaneously stimulating the expression of genes important for lipid metabolism. An analysis of genetic markers from the current study is ongoing.
"The totality of published literature, combined with the effect of VK2809 on hepatic lipids, collagen content, fibrosis and NAS observed in the diet-induced disease model suggest an encouraging potential benefit in NASH," stated Dr. Lian.
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 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.
