ROME – Treating patients with heterozygous familial hypercholesterolemia (HeFH) with PCSK9 inhibitors can reduce their need for lipoprotein apheresis and its associated costs, Patrick M. Moriarty, MD, said in a video interview at the annual congress of the European Society of Cardiology.
In the randomized, phase III ODYSSEY ESCAPE trial, HeFH patients who underwent weekly apheresis were treated with either alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, or placebo. At the end of the study, the alirocumab-treated patients had a 75% greater reduction in need for apheresis, compared with those on placebo – a statistically significant difference.
With a price tag of $50,000-$75,000 a year for lipoprotein apheresis, compared with the roughly $12,000 cost for a PCSK9 inhibitor, this represents a significant savings for patients with HeFH, which occurs in roughly 1 in 200 people worldwide, Dr. Moriarty of the University of Kansas, Kansas City, told reporter Bruce Jancin.
