BOSTON and CARLSBAD, Calif., Aug. 29, 2020 /PRNewswire/ — Akcea Therapeutics, Inc. (NASDAQ: AKCA), a majority-owned affiliate of Ionis Pharmaceuticals, Inc., and Ionis Pharmaceuticals, Inc. (NASDAQ: IONS), presented data from the Phase 2 clinical trial of vupanorsen (AKCEA-ANGPTL3-LRx) in an online Late Breaking Clinical Trial Session at the ESC Congress 2020, the annual meeting for the European Society of Cardiology.
Vupanorsen is an investigational antisense therapy being developed to treat patients with certain cardiovascular diseases. In the Phase 2 study, vupanorsen met the primary endpoint of significant reductions in triglyceride (TG) levels and multiple secondary endpoints compared to placebo, with a favorable safety and tolerability profile.
“We are very encouraged by the demonstrated efficacy, safety and tolerability profile of vupanorsen,” said Damien McDevitt, Ph.D., chief executive officer at Akcea. “There are millions of patients worldwide living with dyslipidemia that puts them at risk of cardiovascular events. By reducing ANGPTL3, vupanorsen has the potential to reduce the risk of cardiovascular events caused by dyslipidemia in many of these patients, thereby addressing a major area of continued unmet medical need. We look forward to working with Pfizer as they continue to advance this important clinical development program.”
Vupanorsen was developed using Ionis’ proprietary LIgand Conjugated Antisense (LICA) technology platform to reduce the production of angiopoietin-like 3 (ANGPTL3) protein from the liver, a key regulator of triglyceride and cholesterol metabolism.
The goal of the randomized, double-blind, placebo-controlled, dose-ranging Phase 2 study was to assess the safety and efficacy of vupanorsen. A total of 105 patients with hypertriglyceridemia (fasting plasma TG levels >150 mg/dL), type 2 diabetes and non-alcoholic fatty liver disease (NAFLD) were randomized to three dosing cohorts in a 3:1 ratio (vupanorsen: placebo) within each cohort and treated for six months. The dosing cohorts explored different doses and dose regimens vs placebo, with patients receiving either 40 mg or 80 mg every four weeks or 20 mg every week. Participants received either vupanorsen or placebo via subcutaneous injection. Results from the Phase 2 study show:
- Statistically significant dose-dependent reductions in fasting TGs at all dose levels, with the highest mean reduction of 53% at the dose of 80 mg every four weeks (44% mean reduction compared to placebo, P0.0001)
- Statistically significant dose-dependent reductions compared to placebo in ANGPTL3 (62%), very low-density lipoprotein (VLDL) cholesterol (38%), total cholesterol (19%), and non-high-density lipoprotein (non-HDL) cholesterol (18%) (numbers indicate mean reductions achieved with the 80 mg every four week dose)
- No effect on glycemic parameters and no decrease in hepatic steatosis
- No significant reductions in low-density lipoprotein cholesterol (LDL-C) levels compared to placebo in this patient population, which did not have high baseline LDL-C levels
- A favorable tolerability and safety profile. The most common treatment-emergent adverse events were injection site reactions, which were mostly mild.
“Antisense-mediated reduction of ANGPTL3 has the potential to address significant unmet needs in patients with cardiovascular diseases,” said Daniel Gaudet, M.D., professor of medicine, Department of Medicine, University of Montreal. “Results from the Phase 2 study bring essential insights about this investigational therapy that may help guide disease management strategies and clinical research moving forward.”
“Clinical data from the Phase 2 study show an impressive and meaningful reduction in triglyceride levels and ANGPTL3, and add to the growing body of evidence supporting our LICA antisense technology for large indications, such as cardiovascular disease,” said Brett P. Monia, Ph.D., chief executive officer at Ionis. “We believe vupanorsen has the potential to bring much-needed benefit to this patient population.”
In November 2019, Akcea and Ionis announced the closing of a worldwide exclusive licensing agreement with Pfizer Inc. for vupanorsen. Pfizer is responsible for all development and regulatory activities and costs beyond those associated with this Phase 2 study. Pfizer plans to further evaluate vupanorsen in a Phase 2b study among statin-treated patients with elevated non-HDL-C and high triglyceride levels, in order to identify the optimal dose to maximize target engagement and lipid lowering. The Phase 2b study is expected to initiate in 2H 2020.
ABOUT VUPANORSEN (AKCEA-ANGPTL3-LRx)
AKCEA-ANGPTL3-LRx (vupanorsen) is an investigational antisense therapy being developed to treat patients with certain cardiovascular diseases. This antisense medicine is designed to reduce the production of angiopoietin-like 3 (ANGPTL3) protein, a key regulator of triglyceride and cholesterol metabolism, in the liver. AKCEA-ANGPTL3-LRx was developed using Ionis’ advanced LIgand Conjugated Antisense (LICA) technology platform. The potential therapeutic benefits of ANGPTL3 reduction are supported by the discovery that people with a genetic deficiency in ANGPTL3 have reduced levels of low-density lipoprotein cholesterol (LDL-C) and triglycerides, and a decreased risk of diabetes and cardiovascular disease.1 In a previous Phase 1 study, subjects treated with AKCEA-ANGPTL3-LRx achieved robust, dose-dependent reductions in ANGPTL3, triglycerides, LDL-C, non-HDL-C and total cholesterol with a positive safety and tolerability profile.2 AKCEA-ANGPTL3-LRx was discovered by Ionis and has been co-developed by Akcea and Ionis.
