Viking Stock Surges As Liver Disease Drug Succeeds In Phase 2 Study

Viking Therapeutics Inc. (VKTX) announced positive top-line results from a 12-week Phase 2 study of VK2809, its novel liver-selective thyroid receptor beta agonist, in patients with non-alcoholic fatty liver disease or NAFLD and elevated low-density lipoprotein cholesterol or LDL-C. The study successfully achieved its primary endpoint, with patients receiving VK2809 demonstrating statistically significant reductions in LDL-C compared with placebo.

In addition, the trial's secondary endpoint was achieved, with VK2809-treated patients experiencing statistically significant reductions in liver fat content compared with placebo.

In Tuesday pre-market trade, VKTX is currently trading at $23.96, up $13.57 or 130.61 percent.

The company noted that patients receiving VK2809 demonstrated statistically significant reductions in LDL-C of 20% or more, compared with placebo-treated patients. In addition, VK2809-treated patients demonstrated statistically significant improvements in other lipids, including atherogenic proteins apolipoprotein B and lipoprotein.

The company said that patients receiving VK2809 experienced statistically significant reductions in liver fat content, as assessed by magnetic resonance imaging, proton density fat fraction (MRI-PDFF), relative to placebo after 12 weeks of treatment.

According to the company, no serious adverse events were reported among patients receiving VK2809 or placebo. Mean alanine aminotransferase (ALT) levels among patients receiving VK2809 were reduced from baseline relative to those of patients receiving placebo. Among patients with elevated baseline ALT levels, those receiving VK2809 also demonstrated reduction relative to placebo.

There were no clinically or numerically meaningful differences in direct bilirubin, indirect bilirubin, alkaline phosphatase, or international normalized ration (INR) between patients treated with VK2809 or placebo. In addition, no meaningful changes to the thyroid hormone axis were observed among VK2809-treated patients compared with placebo-treated patients.
