Reductions in Very Long-Chain Fatty Acids and Plasma Lipid Levels Observed After 28 Days of Once Daily Dosing VK0214 Shown to be Safe and Well-Tolerated in 28-Day Study SAN DIEGO , Oct. 9, 2024 /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 data from the company's Phase 1b clinical trial of VK0214, a novel small molecule agonist of the thyroid hormone receptor beta (TRβ), in patients with X-linked adrenoleukodystrophy (X-ALD).
Results from this study showed VK0214 to be safe and well-tolerated following once-daily dosing over the 28-day study period. In addition, significant reductions were observed in plasma levels of very long-chain fatty acids (VLCFAs) and other lipids, as compared to placebo. Highlights from the study results include: Reductions in VLCFAs In addition to safety and tolerability, the study included an exploratory assessment of changes in plasma levels of VLCFAs after 28 days of dosing.
VLCFAs are considered biomarkers of disease in patients with X-ALD. Treatment with VK0214 resulted in significant reductions in mean VLCFA levels at both doses evaluated, 20 mg/day and 40 mg/day, compared to placebo. Importantly, cohorts receiving VK0214 demonstrated reductions in mean plasma levels of the 26 carbon lysophosphatidyl choline (C26:0-LPC) derivative, a key diagnostic marker.
