Literature Review
• Conclusions:
• Alirocumab significantly reduces LDL-C
when added to maximum tolerated statin
therapy in patients with heterozygous
familial hypecholesterolemia and patients
with CHD or CHD risk equivalent
• In the post-hoc analysis, there was
evidence of reduction in the rate of CV
events with alirocumab
Robinson JG, et al. N Engl J Med. 2015;372:1489-99
Praluent® - alirocumab
Summary
• Praluent® (alirocumab) is the first-in-class PCSK9
inhibitor that reduces LDL-C
• Indicated for the treatment of adults with
heterozygous familial hypercholesterolemia or
clinical ASCVD, who require additional LDL-C
lowering despite diet and maximally tolerated
statin therapy
• Dose is 75 or 150 mg every 2 weeks given as a SC
injection
• The most common AEs observed include
hypersensitivity reactions
• LDL-C should be monitored within 4-8 weeks
