Volanesorsen: First Global Approval

Volanesorsen (Waylivra^®), an antisense oligonucleotide inhibitor of apolipoprotein CIII (apoCIII) mRNA, is being developed by Ionis Pharmaceuticals through its subsidiary company, Akcea Therapeutics, to treat familial chylomicronemia syndrome (FCS), hypertriglyceridemia and familial partial lipodystrophy (FPL). In May 2019, volanesorsen was approved in the EU for the treatment of adult patients with FCS based on positive results from the multinational, phase III APPROACH and COMPASS studies. Other clinical trials are ongoing to assess its utility in hypertriglyceridemia, FPL and partial lipodystrophy. This article summarizes the milestones in the development of volanesorsen leading to this first approval as an adjunct to diet in adult patients with genetically confirmed FCS and at high risk for pancreatitis, in whom response to diet and triglyceride lowering therapy has been inadequate.
