CAMBRIDGE, Mass., Nov. 15, 2016 /PRNewswire/ -- Akcea Therapeutics, a wholly-owned subsidiary of Ionis Pharmaceuticals, Inc. (NASDAQ: IONIS), today announced positive results from an interim analysis of a Phase 1/2a study of IONIS-ANGPTL3-LRx. In this study, subjects with elevated triglycerides achieved substantial and statistically significant mean reductions in angiopoietin-like 3 (ANGPTL3), triglycerides and LDL-cholesterol of up to 83 percent, 66 percent, and 35 percent, respectively. The study was presented today at the American Heart Association Scientific Sessions by Sotirios Tsimikas, M.D., professor of medicine and director of vascular medicine at the University of California, San Diego, and vice president of clinical development at Ionis Pharmaceuticals.
"These data provide solid support for the therapeutic potential of ANGPTL3 to reduce multiple lipid risk factors in patients with cardiovascular disease and to affect liver fat accumulation in patients with NASH," said Dr. Tsimikas. "Pre-clinical studies in animal models of atherosclerosis and obesity demonstrate that lowering ANGPTL3 levels with antisense oligonucleotides significantly reduces progression of atherosclerosis and liver fat accumulation. The potential of ANGPTL3 reduction to improve cardiovascular risk is also supported by genetic studies in humans with both heterozygous and homozygous loss-of-function mutations in their ANGPTL3 gene showing that individuals with lower or absent plasma levels of ANGPTL3 protein exhibit low plasma levels of triglycerides and LDL cholesterol, which are both risk factors for cardiovascular disease."
Subjects who received multiple doses of 10 mg, 20 mg, 40 mg, or 60 mg of IONIS-ANGPTL3-LRx achieved dose-dependent, statistically significant mean reductions at Day 37 in ANGPTL3 of up to 83 percent (p 0.001). These subjects also experienced statistically significant mean reductions in triglycerides of up to 66 percent (p 0.001), in LDL-C of up to 35 percent (p 0.001), and in total cholesterol of up to 36 percent (p 0.001). In this study, IONIS-ANGPTL3-LRx displayed a favorable safety and tolerability profile. There were no discontinuations due to adverse events and no clinically meaningful platelet declines.
"These study results support the potential to develop IONIS-ANGPTL3-LRx to treat multiple diseases, such as severe dyslipidemias and NASH," said Paula Soteropoulos, president and chief executive officer of Akcea Therapeutics. "With its focus on cardio-metabolic disorders, Akcea is uniquely positioned to advance the therapeutic and commercial potential of IONIS-ANGPTL3-LRx."
IONIS-ANGPTL3-LRx is a LIgand Conjugated Antisense (LICA) drug designed to reduce the production of the ANGPTL3 protein, a key regulator of plasma lipids, such as triglycerides and LDL-cholesterol. Ionis' LICA technology is designed to enhance the potency of its drugs by increasing efficient drug uptake in target tissues, which provides the potential for improved therapeutic margin, improved tolerability and dosing schedule flexibility.
"In this study, IONIS-ANGPTL3-LRx, demonstrated, consistent with the data we have observed with our other LICA drugs, the ability to robustly lower its intended target at much lower doses than previously used to achieve similar target reduction with our non-LICA drugs," said Richard Geary, Ph.D., senior vice president of development at Ionis Pharmaceuticals. "These data further confirm that the profile conferred by our LICA technology demonstrate the potential of these advanced antisense drugs to address broader patient populations in cardiovascular and in non-cardiovascular indications because of the very low volume, infrequent and well-tolerated subcutaneous dosing these drugs can provide."
