Groundbreaking FDA Approval: TRYNGOLZA™ Becomes First Treatment for Familial Chylomicronemia Syndrome

TRYNGOLZA™ Approved as the First Treatment for Familial Chylomicronemia Syndrome

In a momentous announcement, Ionis Pharmaceuticals, Inc. has received FDA approval for TRYNGOLZA™ (olezarsen) as an adjunct treatment to diet aimed at reducing triglyceride levels in adults suffering from familial chylomicronemia syndrome (FCS). This approval marks a significant milestone in the medical community, as it represents the first available treatment for this rare, genetic disorder characterized by extremely high triglyceride levels, leading to severe health risks such as acute pancreatitis.

FCS is a debilitating condition that severely impairs the body's ability to effectively break down fats due to a deficiency in the enzyme lipoprotein lipase. Consequently, individuals with FCS often experience triglyceride levels exceeding 880 mg/dL, resulting in chronic symptoms like fatigue, nausea, and acute episodes of abdominal pain. For many, this diagnosis comes with psychological and financial strains, impacting their overall quality of life. In the U.S., it is estimated that roughly 3,000 people are affected by FCS, with many remaining undiagnosed.

The Importance of TRYNGOLZA™

TRYNGOLZA™ is designed to tackle the challenges presented by FCS by significantly lowering triglyceride levels and consequently reducing the frequency of acute pancreatitis events. In the global Phase 3 Balance trial, involving adults with genetically confirmed FCS, TRYNGOLZA demonstrated a remarkable placebo-adjusted mean reduction in triglycerides by 42.5% after six months. This reduction further improved to 57% after twelve months, showcasing the treatment's efficacy.

Notably, the trial indicated a substantial reduction in acute pancreatitis events, with only 5% of participants in the TRYNGOLZA group experiencing such events compared to 30% in the placebo group. This not only emphasizes the drug’s effectiveness but also reflects its potential to greatly enhance the quality of life for individuals living with this serious condition. Brett P. Monia, Ph.D., CEO of Ionis, highlighted the transformative nature of this approval for patients and their families, suggesting that for the first time, adults living with FCS would have a biomedical option to manage their condition.

A Comprehensive Treatment Approach

TRYNGOLZA™ is administered monthly via an auto-injector, making it a practical option for many patients. It is intended to be used alongside strict dietary restrictions, particularly a low-fat diet limited to 20 grams per day, which is crucial in managing triglyceride levels.

The approval of TRYNGOLZA is not just a breakthrough for patients but also a pivotal point for Ionis Pharmaceuticals, signaling their growth into a fully integrated commercial-stage biotechnology company. The company has plans to introduce additional innovative treatments in the coming years, harnessing its expertise in RNA-targeted therapies.

Recognizing the FCS Community

Both healthcare professionals and patients have expressed the relief and hope this new medication brings. Alan Brown, M.D., emphasized the long-standing reliance on strict dieting as the only preventative measure until now. The ability to prescribe a treatment that actively lowers triglyceride levels is a revolutionary step forward for doctors managing FCS. Lindsey Sutton Bryan from the FCS Foundation echoed this sentiment, expressing the community's long-standing struggle with limiting treatment options and how the approval provides a renewed sense of hope.

Ionis is committed to ensuring patients have access to TRYNGOLZA™, providing resources and support through their program, Ionis Every Step™, which includes education and assistance with insurance to navigate this new treatment journey. As TRYNGOLZA™ prepares to arrive in U.S. markets before year-end, the anticipation within the FCS community grows strong.
