Heterozygous familial hypercholesterolemia and dyslipidemia are the predominant causes for cardiovascular disease (CVD). Clinical guidelines for lowering CVD risk have advocated that low density lipoprotein-cholesterol (LDL-C) must be reduced. The primary choice of therapy for controlling lipidemia has been statins, which are not completely effective. Proprotein convertase subtilisin/kexin type-9 (PCSK9), which interferes with LDL clearance from circulation, inversely relates to the LDL-C levels. The loss of statin efficacy is likely due to increased circulating PCSK9 and antibody therapy against PCSK9 has been found to be efficacious in lowering LDL-C. In this study, we evaluated the efficacy of PCSK9-mAbs for lowering LDL-C, in statin non-responsive hypercholesterolemia patients.PubMed, EMBASE, Scholar, Web of Science and Scopus databases were searched to identify randomized controlled trials of PCSK9 antibody–statin combination vs statin, published till 2015. Two reviewers independently screened the articles, and a collective decision was reached about the included studies in the metaanalysis. Parameters analyzed: change from baseline in LDL-C, high-density lipoprotein cholesterol (HDL-C) and total cholesterol (TC); ApoB and ApoA1 levels.A total of 12 studies with 4909 patients were selected. Overall, add-on therapy with PCSK9-mAb to the ongoing statin therapy was found to achieve greater reduction in LDL-C, ApoB, TC, compared to statin therapy. There were no major treatment emergent adverse effects due to PCSK9-mAb therapy.In adult patients with heterozygous familial hypercholesterolemia and dyslipidemia, PCSK9-mAb therapy in combination with statins was able to achieve the goal of lowering LDL-C.
