BOSTON and CARLSBAD, Calif., Nov. 08, 2018 (GLOBE NEWSWIRE) -- Akcea Therapeutics, Inc. (NASDAQ: AKCA), an affiliate of Ionis Pharmaceuticals, Inc., and Ionis Pharmaceuticals, Inc. (NASDAQ: IONS), today announced that clinical data on AKCEA-APO(a)-LRx in patients with established cardiovascular disease (CVD) and elevated levels of lipoprotein(a), or Lp(a), will  be presented at the American Heart Association Scientific Sessions in Chicago November 10-12, 2018. AKCEA-APO(a)-LRx is an antisense drug developed using Ionis’ proprietary LIgand Conjugated Antisense, or LICA technology platform.   

AKCEA-APO(a)-LRx is designed to inhibit production of apolipoprotein(a), or Apo(a) protein, thereby reducing systemic levels of lipoprotein(a), or Lp(a). Elevated Lp(a) is an independent, hereditary risk factor for CVD that cannot be well controlled with lifestyle modifications, such as diet or exercise, or with treatment using existing cholesterol-lowering therapies. It is estimated that there are 8 to 10 million treatable patients living with cardiovascular disease and elevated levels of Lp(a).

Following is information about the late-breaking presentation of AKCEA-APO(a)-LRx:

Saturday, November 10, 2018 from 4:15-4:25 pm CDT

  • Safety and Efficacy of AKCEA-APO(a)-LRx to Lower Lipoprotein(a) Levels in Patients With Established Cardiovascular Disease: A Phase 2 Dose-Ranging Trial will be presented by Sotirios Tsimikas, M.D., FACC, FAHA, FSCAI, Univ California San Diego, and vice president of global cardiovascular development at Ionis Pharmaceuticals, La Jolla, CA (Session LBS.02 – Late Breaking Clinical Trial: Novel Approaches to CV Prevention; Main Event 1)

Akcea will have an on-site presence at the meeting at booth 826 in the Science & Technology Hall where attendees can learn more about TEGSEDI™ (inotersen).

ABOUT AKCEA-APO(a)-LRx AND THE PHASE 2 STUDY

Akcea and Ionis announced positive topline results in September 2018 from the Phase 2 study demonstrating a significant reduction in Lp (a) and a favorable safety and tolerability profile. Results from the study showed most patients in the active group achieved Lp(a) reductions below the established threshold of risk for cardiovascular disease events. The Phase 2 randomized, double-blind, placebo-controlled, dose-ranging study evaluated the safety and efficacy of different doses of AKCEA-APO(a)-LRx in 286 patients with elevated levels of Lp(a) and established cardiovascular disease. The study had a five to one randomization testing different doses and dose frequencies of AKCEA-APO(a)-LRx. Weekly, every other week and monthly doses were tested ranging from 20mg to 60mg. Patients were dosed for at least six months with some patients dosed up to one year. The primary efficacy endpoint was the percent change in Lp(a) from baseline at the primary analysis time point (6 months) compared to placebo.

AKCEA-APO(a)-LRx is an antisense drug that uses Ionis’ advanced LIgand Conjugated Antisense, or LICA technology. AKCEA-APO(a)-LRx inhibits the production of apolipoprotein(a), or Apo(a), protein, thereby reducing Lp(a).

ABOUTLp(a)
Lipoprotein(a), or Lp(a) is made up of apo(a) protein bound to LDL cholesterol and contains oxidized phospholipids, resulting in an atherogenic, pro-inflammatory and thrombogenic lipoprotein. Elevated Lp(a) is recognized as an independent, genetic cause of cardiovascular disease present in approximately 20-30% of the population. Lp(a) levels are determined at birth and, therefore, cannot be well controlled with lifestyle modifications, including diet and exercise.

For additional information about Lp(a), please see the Lipoprotein(a) Foundation at http://www.lipoproteinafoundation.org/.

ABOUTTHEAKCEAANDNOVARTISCOLLABORATION
In January 2017, Akcea entered into an exclusive, worldwide option and collaboration agreement with Novartis to develop and commercialize AKCEA-APOCIII-LRx and AKCEA-APO(a)-LRx. Along with the Phase 2 study of AKCEA-APO(a)-LRx reported here, Akcea is also conducting a Phase 2b dose-ranging study for AKCEA-APOCIII-LRx in patients with hypertriglyceridemia and established cardiovascular disease with data planned in 2019. The goal of both studies is to choose the optimal dose and evaluate alternative dose schedules, such as monthly dosing, for Phase 3 cardiovascular outcomes studies. Novartis has the option to license each drug after completion of the Phase 2 dose-ranging study and end-of-Phase 2 meeting with FDA. Upon option exercise for each drug, Novartis will pay Akcea a $150 million license fee of which 50% will be paid to Ionis. If licensed, Novartis plans to conduct a global Phase 3 cardiovascular outcome study in high-risk patients. Novartis will be responsible for worldwide development and, if approved, co-commercialization activities. As part of the collaboration, Akcea has the rights to co-commercialize Akcea-APO(a)-LRx in selected markets, on mutually agreed terms and conditions.
