CAMBRIDGE, MA, USA I November 13, 2017 I Akcea Therapeutics, Inc. (NASDAQ:AKCA), an affiliate of Ionis Pharmaceuticals, Inc. (NASDAQ:IONS), focused on developing and commercializing drugs to treat patients with serious cardiometabolic diseases caused by lipid disorders, today announced the initiation of an exploratory Phase 2 program of AKCEA-ANGPTL3-LRx in patients with rare hyperlipidemias.
AKCEA-ANGPTL3-LRx is designed to reduce the production of angiopoietin-like 3, or ANGPTL3. The absence of ANGPTL3 has been shown to be cardioprotective and associated with reduced risk of insulin resistance and diabetes mellitus.
The AKCEA-ANGPTL3-LRx Phase 2 program is designed to include three clinical studies in patients with one of three rare hyperlipidemias, including familial chylomicronemia syndrome (FCS), familial partial lipodystrophy (FPL), and homozygous familial hypercholesterolemia (HoFH). The objectives of these studies are to determine the pharmacodynamics, pharmacokinetics, safety and tolerability of AKCEA-ANGPTL3-LRx, and to further characterize the drug’s potential in these patient populations.
“ANGPTL3 is a key regulator of a number of lipid and metabolic pathways and as such is an important target for the therapeutic management of rare hyperlipidemias, such as FCS, FPL and HoFH. In FCS, severe elevation of triglycerides results in a high risk of acute and chronic pancreatitis and other metabolic complications. Patients with HoFH are subject to early cardiovascular disease and premature death due to high LDL cholesterol levels. Patients with FPL often have both high triglycerides and high LDL cholesterol levels as well as other complications related to insulin resistance and fatty liver, which can lead to accelerated atherogenesis and liver failure,” said Louis O’Dea, chief medical officer at Akcea Therapeutics. “We are committed to developing additional therapeutic options for these patient populations whose significant medical needs are currently greatly underserved.”
Consistent with Akcea’s commitment to the FCS community, the first study is designed to evaluate the pharmacodynamics, pharmacokinetics, safety and tolerability of AKCEA-ANGPTL3-LRx in patients with FCS. Study participants will receive AKCEA-ANGPTL3-LRx by subcutaneous injection once weekly for 13 weeks. Akcea plans to report top-line data from this study in 2018. Akcea plans to initiate similar pilot studies shortly in patients with FPL and patients with HoFH. For further study information, please visit www.clinicaltrials.gov and search for AKCEA-ANGPTL3-LRx.
AKCEA-ANGPTL3-LRx is a ligand conjugated antisense (LICA) drug designed to reduce angiopoietin-like 3 protein, or ANGPTL3. ANGPTL3 is a key regulator of triglycerides, cholesterol, glucose and energy metabolism. People with lower levels of ANGPTL3 have lower LDL-C and triglyceride levels and lower risk of heart attacks. Ionis and Akcea are developing AKCEA-ANGPTL3-LRx to treat multiple lipid disorders including rare hyperlipidemias and NAFLD with metabolic complications.
In a Phase 1/2 clinical study in volunteers with elevated triglycerides, published in The New England Journal of Medicine, treatment with multiple doses of AKCEA-ANGPTL3-LRx resulted in dose-dependent reductions in ANGPTL3 protein of up to 85% after six weeks of treatment. Treatment with AKCEA-ANGPTL3-LRx also resulted in substantial and dose-dependent reductions in triglycerides, LDL cholesterol, VLDL cholesterol, non-HDL cholesterol, apolipoprotein B and apolipoprotein C-III protein. AKCEA-ANGPTL3-LRx was well tolerated in the study. No serious adverse events, including platelet count reductions and injection site reactions, were reported. Further, there were no discontinuations during the treatment period. Phase 1 studies of all three of Akcea’s LICA drugs have shown that doses up to 30 fold lower than non-LICA drugs result in consistent target reductions and a favorable safety and tolerability profile.
