Abstract

Statins are indicated for treatment of patients with heterozygous familial hypercholesterolaemia: these drugs inhibit hepatic cholesterol synthesis and indirectly raise transcription and expression of low-density lipoprotein (LDL) receptors, resulting in augmented residual LDL receptor function. Unfortunately, estimates of the effectiveness of statins in this setting are missing, since placebo-controlled trials in patients with familial hypercholesterolaemia have not been done. Observational evidence about statin treatment in a UK cohort 1 Neil A Cooper J Betteridge J et al.

Effect of a monoclonal antibody to PCSK9, REGN727/SAR236553, to reduce low-density lipoprotein cholesterol in patients with heterozygous familial hypercholesterolaemia on stable statin dose with or without ezetimibe therapy: a phase 2 randomised controlled trialREGN727 was well tolerated and achieved substantial further LDL-C reduction in patients with heterozygous familial hypercholesterolaemia and elevated LDL-C treated with high-dose statins, with or without ezetimibe. REGN727 has the potential to provide optimum control of LDL-C in patients with this disorder. Full-Text PDF
