Ionis and Akcea Recognize FCS Awareness Day With Global Community Efforts to Celebrate Unsung Heroes

BOSTON & CARLSBAD, Calif.--()--Ionis Pharmaceuticals (NASDAQ: IONS) and its wholly owned subsidiary, Akcea Therapeutics, today recognize the 3rd annual Familial Chylomicronemia Syndrome (FCS) Awareness Day, a global observance held each year on the first Friday in November to build broader awareness of the challenges associated with this debilitating, ultra-rare disease. Together with members of the FCS community, Ionis and Akcea have made significant progress in efforts to help people around the world learn about FCS and the impact it has on patients, their families and caregivers.

We are proud to join forces with the FCS community to bring awareness to this devastating disease. Today, we shine a light on the patients, caregivers and families who live with the burden of this disease and we celebrate the members of the global FCS community who are leading the charge to drive awareness of FCS,” said Kristina Bowyer, vice president of patient centric drug development at Ionis. “Advocates including Melissa Goetz and Lindsey Sutton from the FCS Foundation, and Jill Prawer from Action FCS, are some of the many humble heroes whose tireless efforts to advocate on behalf of patients and families is inspiration for our work. Their strength and commitment, especially during a very challenging year, give our teams a renewed dedication to support their needs.”

FCS is a genetic disease caused by impaired function of the enzyme lipoprotein lipase (LPL), which results in elevated triglyceride levels and significant risk and disease burden. This may include unpredictable and potentially fatal acute pancreatitis as well as chronic complications due to permanent organ damage. It is estimated that there are between 3,000 to 5,000 people living with FCS worldwide. Patients must manage their triglyceride levels by adopting a strict, extremely low-fat diet of 10-20g of fat per day, which is incredibly challenging and does not remove the risk of pancreatitis and other symptoms of the disease.

To drive attention to FCS Awareness Day, employees from both Ionis and Akcea will participate in an FCS diet challenge where they must adhere to the strict, low-fat diet that patients live by every day for the entire FCS Awareness Day. The companies also encourage employees and members of the global FCS community to participate in a recipe challenge where they can share creative recipes including FCS-friendly foods. Ionis and Akcea plan to share their activities on social media using hashtags #FCSAwarenessDay, #chylomicronemia, #ActionFCS, and #LPLD. The recipes are available here.

I have always lived with the challenges of the low-fat FCS diet and the impact it has had on me physically, emotionally and socially – I would often avoid social engagements with friends and family,” said Krish, a London resident who lives with FCS. “I am grateful to companies like Akcea and Ionis for highlighting the unique challenges that people affected by FCS experience daily and their efforts to support patients. Together, we must continue to raise awareness of this challenging and debilitating rare disease on a global scale.”

About FCS

FCS is an ultra-rare disease caused by impaired function of the enzyme lipoprotein lipase (LPL) and characterized by severe hypertriglyceridemia (>880mg/dL or 10mmol/L) and a risk of unpredictable and potentially fatal acute pancreatitis. Because of limited LPL production or function, people with FCS cannot breakdown chylomicrons, lipoprotein particles that are 90 percent triglycerides. In addition to acute pancreatitis, FCS patients are at risk of chronic complications due to permanent organ damage, including chronic pancreatitis and pancreatogenic (type 3c) diabetes. They can experience daily symptoms including abdominal pain, generalized fatigue and impaired cognition that affect their ability to work. People with FCS also report major emotional and psychosocial effects including anxiety, social withdrawal, depression and brain fog.
