Diabetes Is Associated With Increased Risk of CV Disease

• Diabetes confers an increased risk for MI, stroke, and PAD1–3

• It is not clear whether diabetes should be considered a cause or a comorbidity of heart failure4

– Diabetes is associated with an increased risk of developing HF in patients with other causes (eg, acute MI) and is believed to promote diastolic dysfunction

• Diabetes is associated with a 2- to 3-fold increase in the risk of CV and all-cause mortality5

Incidence of CHF(cases per 100 person-years)

CHF = congestive heart failure; T2DM = type 2 diabetes mellitus; CI = confidence interval.

Retrospective cohort study to update estimates of CHF rate in patients with T2DM

– Follow-up of up to 72 months

1,167 of 8,231 patients with T2DM had incident CHF, vs 526 of 8,845 patients without T2DM

Patients with T2DM experienced CHF at 2.5 times the rate of comparison subjects without T2DM

FDA Guidance for Industry to Evaluate CV Risk in New Antihyperglycemic Medications- July 2008

• Effects on CV risk to be more thoroughly addressed during antihyperglycemic medication development

• Recommendation to demonstrate that therapy will not result in unacceptable increase in CV risk

• Key areas to be addressed by study sponsors (inclusion of patients with a higher risk of CV events [eg, patients with advanced CV disease, elderly patients, and patients with impaired renal function], study duration ≥2 years)

T2DM = type 2 diabetes mellitus; CV = cardiovascular.

TECOS CV Safety Trial: Summary of Results1

Sitagliptin met primary end point (no increased CV risk) when added to usual care in patients with type 2 diabetes and established CV disease

Sitagliptin therapy did not increase all-cause mortality, CV death, or non-CV death

No between-group difference in hospitalization for heart failure

Sitagliptin treatment not associated with a significant increase in severe hypoglycemia

TECOS CV Safety Trial: Summary of Results (continued)1

Fewer patients receiving sitagliptin treatment required additional antihyperglycemic agents or initiation of long-term insulin therapy

Acute pancreatitis uncommon, numerically more frequent in sitagliptin group, whereas pancreatic cancer uncommon, numerically more frequent in placebo group

– Between-group differences not statistically significant

Key Takeaways Messages

• Sitagliptin therapy has been shown to be effective in lowering blood glucose when administered as monotherapy or when used in combination with metformin in appropriate patients with type 2 diabetes1–8

• Combination therapy with sitagliptin and metformin improves glycemic control in appropriate patients with type 2 diabetes, with a low risk of hypoglycemia and no weight gain1–8

• TECOS CV Safety Trial showed that treatment with sitagliptin did not increase the risk of major CV events, and did not increase hospitalization for heart failure9

Significance• Most people with type 2 diabetes need antihyperglycemic medicines to help

control their blood sugar10

• Because people with type 2 diabetes are at increased risk for CV events, understanding the CV safety of these medicines is important9

– Objective of TECOS CV Safety Trial was to assess the CV safety of sitagliptin in patients with type 2 diabetes and established CV disease
