Amgen's AMG 145 Lowers Bad Cholesterol Levels

Amgen Inc. (AMGN) Monday said its experimental drug AMG 145 in combination with statin therapy reduced bad cholesterol levels in patients.

AMG 145 is an investigational antibody directed against PCSK9, a protein that reduces the liver's ability to remove low density lipoprotein cholesterol (LDL-C) or bad cholesterol from the blood.

Amgen in a statement said AMG 145 in combination with statin therapy, with or without ezetimibe, resulted in a reduction in LDL-C by up to 56 percent in patients with heterozygous familial hypercholesterolemia (HeFH) in the Phase 2 Rutherford study.

HeFH, one of the most common genetic disorder, elevates the cholesterol and LDL-C levels and leads to cardiovascular diseases and death.

The company said treatment with AMG 145 every four weeks resulted in a significant LDL-C decrease versus placebo in HeFH patients on lipid-lowering therapy.

At week 12, LDL-C reduction was 43 percent and 55 percent with AMG 145 350 mg and 420 mg, respectively, compared to a 1 percent increase with placebo arm.

"Despite existing therapies and maintaining a healthy lifestyle, patients with heterozygous familial hypercholesterolemia are prematurely at risk for serious cardiovascular disease due to the difficulty in reducing their LDL-C levels," said Frederick Raal, Carbohydrate & Lipid Metabolism Research Unit, Division of Endocrinology & Metabolism, Department of Medicine, University of the Witwatersrand, Johannesburg.
