Learning Objectives

Upon completion of this activity, participants will be able to:

▪ Discuss the role of LDL-C lowering in cardiovascular risk reduction with

emphasis on the results of recently completed clinical trials

▪ Evaluate recommendations for lipid lowering agents beyond or in addition to

statin therapy for patients with atherosclerotic cardiovascular disease

▪ Explain the mechanism of action of proprotein convertase subtilisin/kexin type

9 (PCSK9) inhibitors and apply the latest clinical data to patient management

strategies

▪ Apply best guideline practice recommendations into routine clinical practice

based on specific patient characteristics

PCSK9 Inhibitors and Their Indications

ASCVD, atherosclerotic cardiovascular disease; HeFH, heterozygous familial hypercholesterolemia; HoFH, homozygous familial hypercholesterolemia; LDL-C, low density lipoprotein cholesterol;

PCSK9, proprotein convertase subtilisin kexin type 9.

1. Praluent Canadian Product Monograph, April 11, 2016; 2. IRepatha Canadian Product Monograph, June 29 2016;

▪ Alirocumab1

– Adjunct to diet and maximally tolerated statin therapy where additional LDL-C lowering is needed in adults with

• HeFH

• Clinical ASCVD

▪ Evolocumab2

– Adjunct to diet and maximally tolerated statin therapy where additional LDL-C lowering is needed in adults with

• HeFH

• Clinical ASCVD

– Adjunct to diet and other LDL-C lowering therapies in persons ≥12 years with HoFH who require additional LDL-C lowering

Recommendations for PCSK9i in

FH and ASCVD

• We suggest the use of PCSK9 inhibitors (evolocumab, alirocumab) to lower LDL-C for

patients with heterozygous familial hypercholesterolemia whose LDL-C remains

above target despite maximally tolerated statin therapy (Conditional recommendation, moderate quality

evidence)

• We suggest that PCSK9 inhibitors be considered to lower LDL-C for patients with

atherosclerotic cardiovascular disease in those not at LDL-C goal despite maximally

tolerated statin +/- ezetimibe therapy (Conditional recommendation, moderate quality evidence)

• We suggest that evolocumab be added to background therapy in patients with

homozygous familial hypercholesterolemia and continued if LDL-C lowering is

documented (Conditional recommendation, moderate quality evidence)
