Ionis announces olezarsen FCS New Drug Application accepted for Priority Review and enrollment in Phase 3 sHTG program completed
Ionis Pharmaceuticals announced the FDA's acceptance of its New Drug Application (NDA) for olezarsen, an investigational RNA-targeted medicine for treating familial chylomicronemia syndrome (FCS). The FDA has granted Priority Review with a PDUFA date set for December 19, 2024. Olezarsen has also received Fast Track, Orphan Drug, and Breakthrough Therapy designations.
Additionally, Ionis completed Phase 3 enrollment for three studies (CORE, CORE2, and ESSENCE) evaluating olezarsen for severe hypertriglyceridemia (sHTG), with results anticipated in the second half of 2025. These studies involve over 2,400 patients and aim to address the life-threatening complications associated with sHTG.
The NDA is supported by positive Phase 3 study results presented at the 2024 ACC Annual Meeting and published in the New England Journal of Medicine.

Ionis Pharmaceuticals' recent announcement offers important insights for investors. The acceptance of the New Drug Application (NDA) for olezarsen by the U.S. FDA, along with the designation of Priority Review, signifies a pivotal milestone. Priority Review is granted to medications that may offer substantial improvements over existing treatments, implying that olezarsen has shown promising efficacy in addressing familial chylomicronemia syndrome (FCS), a condition with no approved treatments in the U.S.
From a financial perspective, the Priority Review's six-month timeline could expedite market entry, potentially leading to earlier revenue generation. Investors should note that the PDUFA date is set for December 19, 2024, a key point for tracking near-term milestones. Moreover, the positive Phase 3 results presented at the American College of Cardiology Annual Meeting, alongside publication in a leading journal, bolster confidence in olezarsen's clinical efficacy.
Additionally, the completion of Phase 3 enrollment for olezarsen's application in severe hypertriglyceridemia (sHTG) highlights the company's progressing pipeline. The ability to address both rare and common conditions enhances Ionis' market potential. The forthcoming results in the second half of 2025 will be another critical point for long-term revenue projections.
Overall, the acceptance of the NDA and the momentum in their clinical trials could positively impact Ionis' stock, though investors should remain vigilant about clinical outcomes and regulatory decisions that could affect market dynamics.
The FDA's acceptance of Ionis' NDA for olezarsen is a significant step in addressing familial chylomicronemia syndrome (FCS), a rare genetic disorder. FCS is characterized by extreme hypertriglyceridemia (high levels of triglycerides in the blood), which can lead to recurrent episodes of acute pancreatitis, a potentially fatal condition. The Priority Review designation underscores the unmet medical need and potential impact of olezarsen in reducing triglyceride levels and associated health risks.
The completion of Phase 3 enrollment for olezarsen in treating severe hypertriglyceridemia (sHTG) is also noteworthy. sHTG is much more common than FCS and can similarly result in life-threatening conditions such as acute pancreatitis. The ongoing trials (CORE, CORE2, ESSENCE) enrolling over 2,400 patients provide a robust sample size to evaluate olezarsen's efficacy and safety.
The Fast Track, Orphan Drug and Breakthrough Therapy designations previously granted by the FDA further reinforce olezarsen’s potential therapeutic benefit. These designations can facilitate expedited development and review processes, which are advantageous for bringing innovative treatments to patients sooner.
For investors, understanding these clinical advancements is key. The promising clinical data and regulatory support position olezarsen as a potentially valuable asset in Ionis' portfolio, contributing to both immediate and long-term growth prospects.

Priority Review is a designation for medicines that have the potential to provide significant improvements in the treatment, prevention or diagnosis of a serious disease, with the expectation of the FDA taking action within six months, compared to 10 months under standard review. The application to the FDA was based on positive results from Balance, a global, multicenter, randomized, double-blind, placebo-controlled Phase 3 study. The study results were presented at the 2024 American College of Cardiology (ACC) Annual Meeting and published simultaneously in The New England Journal of Medicine (NEJM).
The
In addition to FCS, Ionis is evaluating olezarsen for the treatment of severe hypertriglyceridemia (sHTG) in three Phase 3 clinical trials – CORE, CORE2 and ESSENCE, all three of which completed enrollment in the first half of 2024. CORE and CORE2 enrolled more than 1,000 sHTG patients with fasting triglyceride levels ≥500 mg/dL; ESSENCE enrolled more than 1,400 high triglyceride patients with fasting triglyceride levels ≥150 mg/dL to <500 mg/dL who were diagnosed and/or at risk for atherosclerotic cardiovascular disease as well as patients with fasting triglycerides ≥500 mg/dL. sHTG is a common, life-threatening condition that can result in severe health complications, including potentially fatal acute pancreatitis (AP). Data are expected in the second half of 2025.
About Olezarsen
Olezarsen is an RNA-targeted investigational LIgand Conjugated Antisense (LICA) medicine being evaluated for people at risk of disease due to elevated triglyceride levels, including those with familial chylomicronemia syndrome (FCS) and severe hypertriglyceridemia (sHTG). Olezarsen is designed to lower the body's production of apoC-III, a protein produced in the liver that regulates triglyceride metabolism in the blood.
Olezarsen is an investigational medicine that has not been reviewed or approved for the treatment of any disease by any regulatory authority.
About FCS
FCS is a rare, genetic disease characterized by extremely elevated triglyceride levels. It is caused by impaired function of the enzyme lipoprotein lipase (LPL). Because of limited LPL production or function, people with FCS cannot effectively break down chylomicrons, lipoprotein particles that are

About sHTG
sHTG is a disease categorized by triglyceride levels of 500 mg/dL and above. It develops due to primary (genetic) and secondary causes including diet and lifestyle, other medical conditions and certain medications. More than three million people are currently estimated to live with sHTG in the U.S. People living with sHTG are at high risk of pancreatitis and damage to the pancreas, as such, reducing the risk of pancreatitis is a critically important reason to treat sHTG. People with sHTG are also at risk of heart, brain and blood vessel damage.
There remains a need for additional therapeutic options for the treatment of sHTG. Endocrinology and cardiovascular treatment guidelines recommend treating triglyceride levels of ≥500 mg/dL to reduce the risk of pancreatitis. Multiple treatment guidelines recommend lifestyle interventions to reduce triglyceride levels in people with sHTG and the addition of a triglyceride lowering medicine such as a fibrate or omega-3 fatty acid if needed to reduce fasting triglycerides to appropriate levels. However, these interventions are not sufficient for all people with sHTG, for whom there remains a significant need for new treatments that may help further reduce triglyceride levels and the risk of pancreatitis.
