Cardiovascular Outcome Trials of Diabetes Medications: Translating

Results into Practice Carol Hatch Wysham, MD

Clinical Professor of Medicine University of Washington

Rockwood Center for Diabetes and Endocrinology Spokane, Washington

WADE Conference April 27, 2019

Disclosures to Participants •  Notice of Requirements for Successful Completion: For successful completion, participants are

required to be in attendance in the full activity and complete the program evaluation at the conclusion of the educational event.

•  Presenter Conflicts of Interest/Financial Relationships Disclosures

Consultant/Advisory Panel: Abbott, Astra Zeneca, Boehringer Ingelheim, Janssen, Novo Nordisk, Sanofi Speaker’s Bureau: Astra Zeneca, Boehringer Ingelheim, Insulet, Janssen, Novo Nordisk, Sanofi

•  Disclosure of Relevant Financial Relationships and Mechanism to Identify and Resolve Conflicts of Interest: Nurse Planner found no issue with conflict of interest or bias. Speaker agrees to the constraints of showing any logos or preference to any product or company. Speaker states slides will be free of any bias.

•  Non-Endorsement of Products: Accredited status does not imply endorsement by AADE, ANCC,

ACPE or CDR of any commercial products displayed in conjunction with this educational activity. •  Off-label Use: Participants will be notified by speakers to any product used for a purpose other than that

for which it was approved by the Food and Drug Administration.

Objectives •  Describe management of CVD and diabetes

therapies prior to CVD Trials •  Explore the history and process of CardioVascular

Outcome Trials (CVOT) •  Compare and contrast published CVOT trials •  Identify upcoming trials •  Explore the role of CDE in CV/DM management –

case studies •  Discuss implications of CVOT and role of changes

made to 2019 ADA Standards of Care guidelines

ADA Recommendations for Statin Therapy1,2

Age, y No Risk Factors ASCVD Risk Factorsa With ASCVD < 40 None Moderate or

high intensity High intensity

40-75 Moderate intensity High intensity High intensity > 75 Moderate intensity Moderate or

high intensity High intensity

If ACS is present and LDL-C ≥ 50 mg/dL or statin intolerant, use moderate-intensity statins + ezetimibe.

•  For every 39-mg/dL reduction in LDL-C3: 21% reduction in MACE, 9% reduction in all-cause mortality

•  PCSK9 inhibitors may be considered in patients at high risk of ASCVD events who are intolerant of high-intensity statin therapy1

a LDL-C ≥ 100 mg/dL, HTN, smoking, chronic kidney disease, albuminuria, and family history of premature ASCVD. b ≈ 1% annual risk of major CV event; BL LDL-C = 127.8 mg/dL, diabetes prevalence ≈ 6%.4

Pharmacologic Interventions • Treatment for hypertension should include drug classes demonstrated

to reduce CV events in patients with diabetes: A

•  ACE Inhibitors

•  Angiotensin receptor blockers (ARBs)

•  Thiazide-like diuretics

•  Dihydropyridine calcium channel blockers

Hypertension/BP Control: Recommendations

SBP target: <140 most, <130 select but relax in elderly (? <150 when >80 yrs)

•  For most outcomes, risk reduction max <140 SBP1 •  <130 SBP further reductions in high risk for CVD,

stroke, retinopathy and albuminuria1,3 • BP < 130/70 associated with increased mortality

in older adults2

Distribution of Risk Factors for Vascular Complications among U.S. Adults with

Diabetes, 1999–2010.

Diabetes and Heart Failure •  Second most common presentation of heart disease in

diabetes (after peripheral vascular disease) •  12% of all cases of HF attributable to DM •  RF: older, long duration DM, insulin treatment, poor

glycemic control •  When coexists with HF, diabetes associated with 53% higher

risk of hospitalization and 50% higher mortality. Median survival 50% in 5 years. •  Costs in 2012: 31 billion, primarily hospitalizations •  #1 reason for hospitalization in those > 65 yrs

McDonald MR et al Eur Heart J, 2008

Heart Failure after MI Associated with High Mortality

•  Retrospective chart review of all patients with first myocardial infarction, without previous diagnosis of heart failure – N = 2596 •  mean follow up 7.6 years •  Results: •  902 developed heart failure (58/1000 pt years)

•  Risk factors: older, female, HTN, DM •  535 developed recurrent MI •  1116 died

•  >50% of deaths occurred after diagnosis of HF (5-fold higher in those without HF)

• Despite all studies showed a lower A1c with active treatment, only LEADER reported lower risk of hypoglycemia: •  Confirmed: HR 0.80 •  Severe: HR 0.69

Hypoglycemia

•  In the studies with GLP-1 RA, the adverse profile was as expected: GI SE, injection site reactions (n = 27,389) . •  In LEADER, there was increase in gallbladder disease •  Despite increases in lipase and amylase, there was no evidence of increase

in risk for pancreatitis nor pancreatic cancer. •  There was no evidence of increased risk for medullary cancer of the thyroid

•  In the studies with SGLT-2 inhibitors, there was increased risk for genital mycotic infections and symptoms of volume depletion (n = 17,162) •  Volume depletion was reported in 26 and 17/1000 pt-years in CANVAS and

EMPA-REG respectively •  There was no increase in risk for UTI, DKA, acute kidney injury,

hyperkalemia.

Other Adverse Events of Interest

•  Changes in traditional CVRF did not explain the outcomes in LEADER nor EMPA-REG.

•  EMPA-REF: Changes in Hct of about 5% (as a measure of volume status) explained about 52% of the effect, followed by FBG at 22% and uric acid at 18%. •  Similar changes in Hct seen with canagliflozin, but not reported in CANVAS paper

•  Direct anti-atherogenic actions postulated for CV effects of liraglutide

What is your primary concern for Carl?

A. Lower his A1c B. Lower his triglycerides C. Weight management D. Lower his risk for recurrent cardiovascular

events &/or death from CVD

In addition to lowering the dose of insulin, what would you suggest for improving his

glycemic control?

A. Add glimepiride B. Add a DPP-4 inhibitor C. Add liraglutide D. Add SGLT-2 inhibitor. E. Suggest bariatric surgery

Treatment considerations for Carl •  Signs of CHF and adequate GFR – good

candidate for SGLT-2 inhibitor •  If SGLT-2 inhibitor is started:

–  Minimize hypoglycemia – consider 20 - 30% reduction in insulin dose (both basal and prandial)

–  DC HCTZ due to expected 5+ mmHg reduction in BP with SGLT-2 inhibitor

–  Encourage increased fluid intake –  Advise about risk for balantitis, if not circumsized

Janice

•  A 62-year-old woman with a 14 year history of T2D is seen for diabetes management. She has history of Right CVA 6 months ago. She has a 40 pack-year history of smoking, but quit after CVA.

•  BP 142/90, BMI 36 kg/m2

•  PE: unremarkable •  Labs: HbA1c 8.5%, eGFR 40 mL/min/

1.73m2, LDL 90, HDL 37, TG 224; ALT normal; UACR 45

•  SMBGs high 100s AM, 200s rest of the day

Medications •  metformin 1000 mg

14

What is your A1c goal for Janice?

A. <6.0% B. <6.5% C. <7.0% D. <7.5% E. <8.0%

What is the best next step to improve glycemic control?

A.  Increase glimepiride to 4 mg BID

B. Add linagliptin 5 mg daily

C. Add lispro with each meal

D. Add canagliflozin 100 mg daily

E. Add liraglutide up to 1.8 mg daily

Treatment Considerations for Janice •  Due to age and serious comorbidities, I would be satisfied with an

A1c in the 7’s. •  With her low GFR, I would opt for substituting liraglutide for

glimepiride –  Ensure up to date on eye exam. –  Advise about GI SE: slow titration –  Advise about risk for gallbladder disease

•  With history of CVA, lower target BP might be indicated, if tolerated

–  Consider an orthostatic BP/P –  Helpful to know the carotid anatomy

•  Consideration for increasing atorvastatin vs adding ezetimibe

What is your primary concern for Albert?

A. Lower his A1c B. Lower his triglycerides C. Weight management D. Lower his risk for recurrent cardiovascular

events &/or death from CVD

Is he a candidate for addition of a GLP-1 RA or SGLT-2 inhibitor?

A. No, his A1c is at target B. No, they are too expensive C. Yes, add liraglutide D. Yes, add an SGLT-2 inhibitor

Treatment considerations for Albert

•  He would be a candidate for either SGLT-2 inhibitor or GLP-1 receptor agonist

•  Cost can be managed by using lower doses: –  Do not titrate > 1.2 mg of liraglutide –  Use ½ tablet of max dose of empagliflozin or

canagliflozin

Summary: Lowering Risk for CVD events in Diabetes

•  Clear evidence ⇓ CVD/mortality in T2DM over several decades, but there remains a large gap over the risk for patients without diabetes –  Better management of CVD risk factors have a major role, but many

sub-optimally treated •  BP and LDL-C reduction > glucose reduction •  Smoking reduction

•  Best time to prevent CVD with glucose control is at diagnosis •  Cardiovascular outcome trials show safety of DPP-4 inhibitors, insulin

glargine, insulin degludec, lixisenatide and exenatide QW •  Data from cardiovascular outcome trials support role of SGLT-2

inhibitors (empagliflozin and canagliflozin) and 2 of the long-acting GLP-1 receptor agonists (liraglutide and semaglutide) for reduction of CVD events in patients with established CVD

Differences within Class: GLP-1 RA •  Only two with demonstrated CV benefit:

liraglutide and semaglutide •  Exenatide QW – barely missed significance –

likely related to high medication discontinuation

•  Lixisenatide – ND – likely related to short duration of action

Differences within Class: SGLT-2 inhibitor

•  Greater impact on CV death with Empagliflozin – in part related to higher CV risk –  Impact on primary endpoint and CHF similar

•  Significant increase in amputations and traumatic fractures seen in CANVAS trial –  Both likely related to greater risk for volume depletion
