- First global regulatory approval for treatment of this rare genetic disease -
SOUTH PLAINFIELD, N.J., Dec. 1, 2022 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT) announced today that the Brazilian Health Regulatory Agency, ANVISA (Agência Nacional de Vigilância Sanitária), has approved Waylivra™ (volanesorsen) as the first treatment for familial partial lipodystrophy (FPL) in Brazil. This is the first approval globally for Waylivra for the FPL indication. Waylivra is also approved in Brazil for the treatment of Familial Chylomicronemia Syndrome (FCS).
"Waylivra's approval as the first treatment for FPL is an important milestone for FPL patients in Brazil," said Stuart W. Peltz, Ph.D., Chief Executive Officer, PTC Therapeutics. "This approval is another example of PTC leveraging its strong capabilities in Latin America to bring first of its kind transformational therapies to patients with high unmet needs."
FPL is a rare genetic metabolic disease characterized by selective, progressive loss of body fat (adipose tissue) from various areas of the body leading to ectopic fat deposition in liver and muscle and development of insulin resistance, diabetes, dyslipidemia, and fatty liver disease1. FPL is a highly burdensome disease, leading to significant metabolic complications that are not managed by current therapies, and it is a distressing condition for the patient.
ANVISA's approval for Waylivra for FPL was based on results from the Phase 2/3 BROADEN study in patients with familial partial lipodystrophy. The study met its primary endpoint demonstrating a statistically significant reduction in triglyceride levels in patients with FPL treated with Waylivra compared to placebo-treated patients.
In the study, there was a mean reduction from baseline of 88 percent in triglyceride levels in patients treated with Waylivra compared to 22 percent reduction in placebo-treated patients at three months. Clinically meaningful and statistically significant reductions in triglyceride levels were sustained over 12 months of treatment in FPL patients. In addition to achieving the primary endpoint, the study achieved an important secondary endpoint of a statistically significant reduction in liver fat.
About Waylivra™Waylivra (volanesorsen) is a product of Ionis Pharmaceuticals, Inc.'s proprietary antisense technology. Waylivra has received conditional marketing approval in the European Union as a treatment for FCS. In addition, Waylivra has been granted Orphan Drug Designation by the European Medicines Agency for the treatment of FCS. The approval by ANIVSA for FPL is the first global approval for this indication.
Waylivra has been in-licensed for commercialization in Latin America by PTC Therapeutics from Akcea Therapeutics, Inc., a wholly-owned subsidiary of Ionis.
About Familial Partial Lipodystrophy (FPL)FPL is a rare lipid disorder characterized by abnormal fat distribution across the body and a range of metabolic abnormalities, including severe insulin resistance, dyslipidemia and hypertriglyceridemia, hepatic steatosis and, in affected women, features of hyperandrogenism. People with FPL often present with polycystic ovarian syndrome or unusually insulin-resistant diabetes and are at increased risk of acute pancreatitis in addition to long-term, progressive consequences including premature cardiovascular disease and liver disease, resulting in cirrhosis. They are unable to store fat or triglycerides in normal fat stores, so excess triglycerides are stored in the liver and muscle and accumulate at high levels in the bloodstream.
About Familial Chylomicronemia Syndrome (FCS)FCS is a rare disease caused by impaired function of the enzyme lipoprotein lipase (LPL) and characterized by severe hypertriglyceridemia (>880mg/dL) and a risk of unpredictable and potentially fatal acute pancreatitis. Because of limited LPL function, people with FCS cannot breakdown chylomicrons, lipoprotein particles that are 90% triglycerides. They can experience daily symptoms including abdominal pain, generalized fatigue and impaired cognition that affects their ability to work. People with FCS also report major emotional and psychosocial effects including anxiety, social withdrawal, depression, and brain fog. The lack of treatments specifically indicated for patients with FCS means that patients must rely on a very restrictive, low-fat diet in combination with lifestyle changes and control of other secondary causes of HTG, which generally do not guarantee the necessary quality of life for those who have FCS. Diet alone does not fully control TG levels and is not sufficient to mitigate the risk of pancreatitis and enzyme replacement therapy would be ineffective in FCS due to half-life limitations.
