BOSTON and CARLSBAD, Calif., Aug. 24, 2020 /PRNewswire/ — Akcea Therapeutics, Inc. (NASDAQ: AKCA), a majority-owned affiliate of Ionis Pharmaceuticals, Inc., and Ionis Pharmaceuticals, Inc. (NASDAQ: IONS), today announced that data from the Phase 2 clinical trial of vupanorsen (AKCEA-ANGPTL3-LRx), an investigational antisense therapy being developed to treat patients with certain cardiovascular diseases, will be presented in a Late Breaking Clinical Trial Session at the upcoming ESC Congress 2020, the annual meeting of the European Society of Cardiology, which is expected to be the world’s largest online gathering of cardiovascular professionals and is taking place August 29-September 1, 2020.

Vupanorsen was developed using Ionis’ proprietary LIgand Conjugated Antisense (LICA) technology platform to reduce the production of angiopoietin-like 3 (ANGPTL3) protein, a key regulator of triglyceride and cholesterol metabolism, in the liver. The Phase 2 dose-ranging clinical trial evaluated the safety and efficacy of vupanorsen in patients with hypertriglyceridemia, type 2 diabetes, and non-alcoholic fatty liver disease (NAFLD).

In November 2019, Akcea and Ionis announced the closing of the worldwide exclusive licensing agreement with Pfizer Inc. for vupanorsen (AKCEA-ANGPTL3-LRx). Under terms of the agreement, Akcea and Ionis received a $250 million upfront license fee, which was split equally between the two companies. Pfizer is responsible for all development and regulatory activities and costs beyond those associated with this Phase 2 study.

Following are details about the late-breaking virtual presentation at ESC Congress 2020, which will be made available on the Akcea website:

  • Late-Breaking Science in Lipids: ANGPTL3 Antisense Oligonucleotide to Lower Triglycerides by Daniel Gaudet, M.D., professor of medicine, Department of Medicine, University of Montreal
    Oral Presentation: Saturday, August 29, 2020, 3:00 a.m. ET/9:00 a.m. CEST


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 cardiovascular disease.1 In a previous Phase 1 study, patients 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.
