Volanesorsen

Identification

Name
Volanesorsen
Accession Number
DB15067
Description

Volanesorsen is an antisense oligonucleotide that binds to apoC-III mRNA to prevent its translation.2 It is indicated to treat familial chylomicronemia, a genetic condition that prevents breakdown of triglycerides and chylomicrons.2 This drug is not commonly prescribed as it is used as an adjunct to diet in patients at high risk for pancreatitis, who have had inadequate response to triglyceride lowering therapy.2

Volanesorsen was granted a conditional approval by the European Medicines Agency.2

Pharmacodynamics

Volanesorsen is an antisense oligonucleotide that prevents the translation of apoC-III.1,2 It has a long duration of action as it has a half life of >2 weeks.2 Patients should be counselled regarding the risk of thrombocytopenia, raised LDL-C levels, renal toxicity, hepatotoxicity, and immunogenicity.2

Mechanism of action

Volanesorsen is an antisense oligonucleotide that binds to apoC-III mRNA, leading to its degradation, and preventing translation of apoC-III protein.2 Normally, apoC-III would inhibit triglyceride metabolism and hepatic clearance of chylomicrons.2 Preventing translation of apoC-III allows for metabolism and breakdown of these triglycerides and chylomicrons.2

Absorption

Volanesorsen is approximately 80% bioavailable.2 A 285mg dose given weekly reaches a Cmax of 8.92 µg/mL, with an AUC of 136 µg*h/mL.2

Volume of distribution

The volume of distribution at steady state is 330 L in patients with familial chylomicronemia.2

Protein binding

Volanesorsen is >98% bound to proteins in plasma.1,2 Though the exact proteins have not been identified.1

Metabolism

Volanesorsen is metabolized by endonucleases and exonucleases in a nonspecific manner.2 The unchanged parent drug is 26% recovered in the urine and pentamer to heptamer sized metabolites account for 55% of urinary recovery.[L16621

Route of elimination

Volanesorsen is predominantly eliminated in the urine, though <3% of a dose was recovered within 24 hours.2

Half-life

Volanesorsen has a half life of >2 weeks.2

Clearance

The exact rate of clearance of volanesorsen is unknown, however it is rapidly distributed to tissues and very slowly eliminated.2
