In patients with heterozygous familial hypercholesterolemia (HeFH) withdrawing from regular apheresis, treatment with evolocumab significantly reduced low-density lipoprotein cholesterol (LDL-C) when compared with LDL apheresis, a recent study found. 11 patients with HeFH undergoing biweekly LDL apheresis were switched to a biweekly subcutaneous injection of 140 mg of evolocumab. The primary endpoints were percent changes in mean LDL-C and apolipoprotein B (apoB) serum levels. Researchers found:
- Evolocumab significantly reduced LDL-C by 62.5% compared with LDL apheresis.
- apoB and serum lipoprotein (a) levels were also significantly reduced.
- No adverse effects were observed other than a mild reduction in vitamin E serum levels.
- Biweekly evolocumab injection therapy is less expensive and less time-consuming compared to biweekly LDL apheresis.
