What is Waylivra (volanesorsen)?

Waylivra (volanesorsen) is indicated as an adjunct to diet in adult patients with genetically confirmed familial chylomicronemia syndrome (FCS) and at high risk for pancreatitis, in whom response to diet and plasma triglycerides lowering therapy has been inadequate.^[1]

How does Waylivra (volanesorsen) work?

The active substance in Waylivra, volanesorsen, is an ‘antisense oligonucleotide,’ a very short piece of synthetic RNA (a type of genetic material). It has been designed to block the production of a protein that slows down the breakdown of fats called apolipoprotein C-III.

By blocking the production of this protein, the medicine shows reduced triglycerides level in the blood of patients with FCS and, as a result, reduced fat accumulation in the body, which is expected to lower the risk of pancreatitis.

Where has Waylivra (volanesorsen) been approved?

Waylivra (volanesorsen) was approved for the treatment of familial chylomicronaemia syndrome (FCS) by:
