Akcea and Ionis report positive topline Phase 2 results of AKCEA-APOCIII-L Rx
The objective of the Phase 2 study was to evaluate the safety and efficacy of different doses and dosing frequencies of AKCEA-APOCIII-LRx. The multicenter, randomized, double-blind, placebo-controlled, dose-ranging study included 114 patients with a clinical diagnosis of CVD or who are at high risk of CVD. Participants were administered AKCEA-APOCIII-LRx or placebo via subcutaneous injection for at least six months with some patients being treated up to a year. Weekly, bi-weekly, and monthly dosing was explored in four cohorts with doses ranging from 10 mg to 50 mg of total monthly dose. Observations from the AKCEA-APOCIII-LRx study included:
- Statistically significant dose-dependent reductions in fasting triglycerides compared to placebo at all dose levels
- At the highest once monthly dose of 50 mg, more than 90% of patients achieved serum triglycerides of ≤ 150 mg/dL, compared to less than 5% of patients in the placebo group; mean triglyceride levels of patients at baseline was 285 mg/dL
- Significant reductions in multiple additional risk factors, including apoC-III, very low-density lipoprotein (VLDL-C) and remnant cholesterol, compared to placebo
- Statistically significant increases in high-density lipoprotein cholesterol (HDL-C) compared to placebo at all dose levels
- Treatment-emergent adverse events (TEAEs) were comparable between active and placebo groups. The most common adverse event was injection site reactions (ISRs). ISRs were mostly mild, infrequent and primarily occurred in the weekly dose group. In the highest monthly dose group, the occurrence of ISRs was similar to the placebo group
- There were no safety signals, including those related to platelet counts, liver function or renal function
- Approximately 85% of patients completed treatment and the rate of treatment discontinuation was comparable between the active and placebo groups
"We are very encouraged that patients achieved a significant reduction in apoC-III and triglyceride levels in this study, with the majority reaching triglyceride levels below the recognized threshold for cardiovascular risk. These data further validate the consistent efficacy and safety profile that we have seen across Ionis' LICA technology platform," said
AKCEA-APOCIII-LRx was discovered by Ionis and has been co-developed by Akcea and Ionis. It is an antisense drug developed using Ionis' proprietary LIgand Conjugated Antisense (LICA) technology platform and is designed to inhibit production of apolipoprotein C-III (apoC-III), a protein produced in the liver that plays a central role in the regulation of serum triglycerides.
ABOUT AKCEA-APOCIII-LRx
AKCEA-APOCIII-LRx is a ligand conjugated antisense (LICA) drug designed to reduce the production of apolipoprotein C-III, or apoC-III. ApoC-III is a protein produced in the liver that plays a central role in the regulation of serum triglycerides. Genetically reduced levels of apoC-III are correlated to lower levels of triglycerides and lower risk of cardiovascular disease whereas elevated levels of apoC-III correlate with high triglyceride levels that have been associated with multiple metabolic abnormalities, such as insulin resistance and/or metabolic syndrome as well as elevated cardiovascular event risk. AKCEA-APOCIII-LRx is in Phase 2 development for hypertriglyceridemia and established cardiovascular disease. Akcea and Ionis intend to pursue development in familial chylomicronemia syndrome, or FCS, and are considering pursuing development in additional indications.
ABOUT
ABOUT
As the leader in RNA-targeted drug discovery and development, Ionis has created an efficient, broadly applicable, drug discovery platform called antisense technology that can treat diseases where no other therapeutic approaches have proven effective. Our drug discovery platform has served as a springboard for actionable promise and realized hope for patients with unmet needs. We created the first and only approved treatment for children and adults with spinal muscular atrophy as well as the world's first RNA-targeted therapeutic approved for the treatment of polyneuropathy in adults with hereditary transthyretin amyloidosis. Our sights are set on all the patients we have yet to reach with a pipeline of more than 40 novel medicines designed to potentially treat a broad range of disease, including neurological, cardiovascular, infectious, and pulmonary diseases.
