Diabetes is a huge and growing problem, and the costs
to society are high and escalating
382 million people have diabetes
By 2035, this number will rise to 592 million

Diabetes management guidelines:
a sense of urgency
HbA1c “... the results of the UKPDS
mandate that treatment of type 2 diabetes include
aggressive efforts to lower blood glucose levels as close to
normal as possible”
“Diabetes must be… diagnosed earlier.
And once diagnosed, all types of
diabetes must then be managed
much more aggressively”

Sitagliptin Improves Glycemic Control In a Glucose-
Dependent Manner By Increasing Concentrations of Active
Incretins1–4
aIncretin hormones GLP-1 and GIP are released by the intestine throughout the day, and their levels increase in response to a meal.
GI = gastrointestinal; GIP = glucose-dependent insulinotropic peptide; GLP-1 = glucagon-like peptide-1; DPP-4 = dipeptidyl peptidase-4; FPG = fasting plasma glucose;
PPG = postprandial plasma glucose.

Study Overview…
This study provides insight about different oral treatment regimens
and their possible effect on initiation of insulin under real-world
conditions.
Real-world research is an important complement to clinical trials as
we seek to improve patient health outcomes.
The objectives of the study were to assess:
• The differences in time to initiation of insulin use.
• The proportion of the population initiating insulin among patients
taking the combination of JANUVIA and metformin, and patients
taking the combination of a sulfonylurea and metformin.Inzucchi et al published online: 22 JUN 2015Diabetes, Obesity and Metabolism 2015
This Observational retrospective cohort study
used a propensity score matched sample from the
GE Centricity Electronic Medical Record database,
initially including 7,728 patients with type 2
diabetes who used JANUVIA (n=3,864) or a
sulfonylurea (n=3,864) as dual therapy with
metformin for (for Six Years) in 2006 to 2013.
Inzucchi et al published online: 22 JUN 2015Diabetes, Obesity and Metabolism 2015
Results…
Results from a late-breaking observational study showed that patients with type 2 diabetes treated
with JANUVIA progressed more slowly to insulin than patients taking a sulfonylurea
(p=0.0034).
This Analysis indicated that at year six, patients in the JANUVIA group were 24 percent
less likely to initiate insulin during the period of observation compared to patients taking a
sulfonylurea (p=0.0011).Inzucchi et al published online: 22 JUN 2015Diabetes, Obesity and Metabolism 2015
Conclusions: In this real-world matched
cohort study, patients with T2DM treated with
sitagliptin had a significantly lower risk of
insulin initiation compared with patients
treated with sulphonylurea, both as add-on to
metformin.

Usual care defined as care provided by patient’s physicians based on local and
institutional practice and regional guidelines, and included continuation of existing
therapy at baseline and adjustment of open-label therapy as required during study
Primary Objective1

Primary OutcomePrimary outcomea was time from randomization to the first confirmedb:
CV-related death, nonfatal MI, nonfatal stroke, or unstable angina requiring hospitalization
Secondary Outcomes Other Prespecified Outcomes

death, nonfatal MI, or nonfatal stroke
Time to the occurrence of the individual
components of the primary end point
Time to all-cause mortality
Time to hospital admission for

Changes from baseline in urinary
albumin:creatinine ratio, eGFR, HbA1c, body weight
Time to initiation of additional antihyperglycemic

Time to non-CV death; time to first CV or peripheral
revascularization procedure; frequency of severe

Counts of outpatient visits and hospitalizations
aIf both MACE+ and MACE analyses met noninferiority and HR <1.0, superiority was to be tested.bCV events were adjudicated by an independent committee, blinded to study therapy.

If HbA1c target not achieved after ~3 months of dual therapy, proceed to 3-drug combination (order not meant to denote any specific preference - choice dependent on a variety of patient- & disease-specific factors):
If HbA1c target not achieved after ~3 months of triple therapy and patient (1) on oral combination, move to injectables, (2) on GLP-1 RA, add basal insulin, or (3) on optimally titrated basal insulin, add GLP-1-RA or mealtime insulin. In refractory patients consider adding TZD or SGL T2-i:

DPP4I Sitagliptin Improves Glycemic Control In a Glucose-
Dependent Manner helping T2DM patients to reach targets without
compromise
Sitagliptin and Metformin combination targets the 3 Metabolic
Defects of Type 2 Diabetes with a reduction in A1c up to -3.6%
Because people with type 2 diabetes are at increased risk for CV
complications, understanding the CV safety of these medicines is
important, That is what the TECOS CV Safety Trial addressed – the
CV safety of Sitagliptin
When considering managing T2DM with CV disease ; Sitagliptin
should be on top of the list.
