Program Objectives
After attending this presentation the participant will be able to:
1. Discuss 2016 Updated ACC Guidelines, NLA and others Recommendations for Dyslipidemia Management
2. Recall that statin therapy is the first line medication treatment for risk reduction
3. Discuss considerations for addition of “other” classes of lipid lowering medication when combination medication therapy is warranted

AHA/ACC Focus on ASCVD Risk Reduction using
4 statin benefit groups
(those who would benefit most from treatment)
• Individuals with clinical ASCVD
Individuals with primary elevations of LDL-C >190 mg/dL
Individuals 40 to 75 years of age with DM and without ASCVD with LDL-C 70-189mg/dL
Individuals without clinical ASCVD or DM who are 40 to 75 years of age with LDL-C 70-189 mg/dL and an estimated 10 year ASCVD
risk of 7.5% or higher
Stone NJ, et al. 2013 ACC/AHA Blood Cholesterol Guideline
ACC 2016 – Why the need for change?
Since the publication of the last guidelines the Food and Drug Administration has approved a new class of meds
proprotein convertase subtillisin/kexin 9 or most often referred to as PCSK9 Inhibitors for at high-risk patients who may
require additional therapies to bring the LDL-C to a more
acceptable threshold
The recent results of the HPS2-THRIVE and IMPROVE-IT trials have also provided new data that provided new
evidence with regard to the addition of second
non-statin agents when additional lowering is warranted

Statin Benefit Groups
Adults ≥21 yrs of age
with clinical ASCVD
on statin for 2°
prevention
Adults ≥21 yrs of age
with LDL-C ≥190 mg/dL
on stain for 1°
prevention
40-75 yrs w/o ASCVD
but with DM & LDL-C 70-
189 mg/dL on statin for
1o prevention
40-75 yrs w/o ASCVD or
DM, LDL-C 70-189 mg/dL
& 10-yr ASCVD risk
≥7.5%, on statin for 1°
prevention
Factors to consider
• Adherence and lifestyle
• Statin intolerance
• Control of other risk factors
• Clinician-patient discussion of the benefits, risks, and patient preferences regarding addition
of non-statin meds
• Percentage LDL-C reduction
• Monitoring of response to therapy, adherence, and lifestyle
Optional interventions to consider
• Referral to lipid specialist and registered dietitian
• Ezetimibe, bile acid sequestrants, or PCSK9 inhibitors
• Mipomersen, lomitapide, LDL apheresis may be considered by a lipid specialist for
patients with familial hypercholesterolemia

*This pathway is consistent with the Non-statin
Therapies Document for individuals with ASCVD with
comorbidity.
Applying the Guideline
SA is a 60 y.o patient with a long history of DM, which is well
controlled at this time and HTN
she has a strong family history of premature heart disease
and is worried about her risk given her DM, poor exercise
history, dietary status and family history
Meds currently include: Metformin ER 2,000 mg daily
Sitagliptin (januvia) 10 mg daily
Hyzaar (ARB) Hctz 50-12 mg/daily
Weight: 154 pounds, height 5’4”, BP 132/88, waist 30”
Last lipid panel > 1 year ago.
How do the guidelines apply?
Individuals 40 to 75 years of age with DM and without ASCVD with LDL-C 70-189mg/dL
The appropriate intensity of statin therapy should be used to reduce ASCVD risk in those most likely to benefit
A high level of evidence supports the use of moderate-intensity statin therapy in persons with diabetes 40 to 75 years of age.
In those of the same age group with diabetes high-intensity statin therapy preferentially for individuals with diabetes and a ≥7.5%

Risk Assessment
for this patient to estimated 10-year ASCVD risk
Problem: consideration for those with diabetes 40 to 75
years of age recognizes that these individuals are at
substantially increased lifetime risk for ASCVD events and
death
individuals with DM experience greater morbidity and worse survival follow the onset of ASCVD
In persons with diabetes <40 or >75 years of age, statin therapy
should be individualized based on considerations of ASCVD risk
reduction benefits, the potential for adverse effects and drug-
drug interactions, and patient preferences
Goal: establish the level of treatment with statin
therapy

Intensity of Statin Therapy
*Individual responses to statin therapy varied in the RCTs and should be expected to vary in clinical practice. There might be a biologic basis for a less-than-average response.
†Evidence from 1 RCT only: down-titration if unable to tolerate atorvastatin 80 mg in IDEAL (Pedersen et al).‡Although simvastatin 80 mg was evaluated in RCTs, initiation of simvastatin 80 mg or titration to 80 mg is not recommended by the FDA due to the increased risk of myopathy, including rhabdomyolysis.

Stone NJ, et al. 2013 ACC/AHA Blood Cholesterol Guideline
Lifestyle as the Foundation for ASCVD Risk Reduction
Efforts
Newest ACC/AHA guidelines adds increased emphasis on
lifestyle management for treatment
It must be emphasized that lifestyle modification (i.e., adhering
to a heart healthy diet, regular exercise habits, avoidance of
tobacco products, and maintenance of a healthy weight)
remains a critical component of health promotion and ASCVD
risk reduction
both prior to and in concert with the use
of cholesterol- lowering drug therapies. Healthy
diet or lifestyle modifications were recommended as
background therapy for the RCTs of cholesterol-lowering drug
therapy.

Role of CYP450 3A4 in Drug Metabolism
• Responsible for converting lipophilic
substrates to water-soluble products to
facilitate urinary excretion
• High potential for drug-drug interactions, as
approximately 50% of drugs are metabolized
by this enzyme
• Hydrophilic agents do not require clinically
significant metabolism through this pathway

IMPROVE-IT: Conclusions
• First trial demonstrating incremental clinical benefit
when adding a non-statin agent (ezetimibe) to statin
therapy:
– Non-statin lowering LDL-C with ezetimibe reduces
cardiovascular events
– Even lower is even better (achieved mean LDL-C 54 vs.
70 mg/dL at 1 year)
– Confirms ezetimibe safety profile
• Reaffirms the LDL hypothesis, which suggests that
reducing LDL-C prevents cardiovascular events

Focus on ASCVD Risk Reduction
Individuals with LDL–C ≥190 mg/dL or triglycerides ≥500 mg/dL should be evaluated for secondary causes of hyperlipidemia
Adults ≥21 years of age with primary LDL–C ≥190 mg/dL should be treated with statin therapy (10-year ASCVD risk estimation is not required)
Use high-intensity statin therapy unless
contraindicated
Stone NJ, et al. 2013 ACC/AHA Blood Cholesterol Guideline
Applying Guideline
Patient has a combined lipid problem but current
LDL-C suggests potential FH with superimposed
elevated TGs and Non-HDL-C
Would not need to use Global Risk Assessment
since 10-year and lifetime risk are very high with FH
Would treat with high intensity statin therapy along
with lifestyle management

Add sulfonylurea?
Add omega 3 fatty acid?

We should consider use of PCSK9-Inhibitors in
patients with:
known CAD or those identified and those who have very
high risk
whose LDL-C cannot be lowered to an acceptable range (goal , generally < 70 mg/dL)
who are on maximally tolerated statin therapy
Use of PCSK9 Inhibitors
*Alternative to percentage LDL-C reduction as a marker for adequate response to therapy.
PCSK9 = proprotein convertase subtilisin/kexin type 9 inhibitor; BAS = bile acid sequestrant; TG = triglyceride

PCSK9 Inhibitors: Obtaining Approval
Low rates of approval for PCSK9 inhibitors FH and LDL-C >190 mg/dL despite LLT

9% of ezetimibe prescriptions rejected
Clinical ASCVD and LDL-C >100 mg/dL despite LLT
57.5% of PCSK9 prescriptions rejected
8.2% of ezetimibe prescriptions rejected
Gaining approval requires use of strong definitions:
Heterozygous or homozygous FH

Barrier Studies and Recommendations
National Lipid Association – A recent study conducted by the National Lipid Association found that 70% of respondents wait more than 30 days from the time of writing the PCSK9i prescription to fulfillment of the first prescription for their patients with FH. Approximately 50% of respondents spend more than 1 hour per week on each patient’s prior authorization.

Proprotein Convertase Subtilisin/KexinType 9 (PCSK9)
• PCSK9: plays an important role in regulating the
expression of the LDL-receptor (LDL-R)
– Secreted primarily by hepatocytes into circulation and
binds to LDL-R on the surface liver cells
– The PCSK9/LDL-R/LDL-C complex is internalized into
hepatocytes and undergoes lysosomal degradation
