Relationship Between Low-Density Lipoprotein Cholesterol and Lipoprotein(a) Lowering in Response to PCSK9 Inhibition With Evolocumab.

ABSTRACT: Background Beyond their potent LDL (low-density lipoprotein) cholesterol ( LDL -C)-lowering efficacy (50-60%), PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitors also reduce Lp(a) (lipoprotein[a]) levels by 25% to 30%, suggesting a 2:1 response ratio. We aimed to characterize the relationship between LDL -C and Lp(a) lowering by evolocumab, a PCSK 9 inhibitor, in a large clinical trial population and to determine the prevalence of concordant/discordant LDL -C and Lp(a) responses to PCSK 9 inhibition. Methods and Results Data were analyzed from 4 randomized, 12-week, multicenter, phase 3 evolocumab trials. Patients with familial hypercholesterolemia, nonfamilial hypercholesterolemia, or statin intolerance participated in the trials. The main measure was the degree of concordan
