Dysglycaemia of Diabetes
Vascular complications in diabetes are mainly or partly dependent
on dysglycaemia
2 components:
• Sustained chronic hyperglycaemia
• Acute glucose fluctuations
Both component lead to diabetes complication through:
• Excessive protein glycation
• Activation of oxidative stress
Monnier L et al. J Diabetes Sci Technol 2008;2:1094-1100 17
Glycaemic variability
Glycaemic variability – an important parameter
used to resolve potential clinical problems in
diabetic patients
Acts as independent risk factor for diabetic
complications, although HbA1c values were
intensely treated

Glucose Tetrad ConceptGlucose fluctuations and activation of oxidative stress contribute to
progression of vascular complications
Monnier L et all. Diabetes Metab Res Rev 2009;25:393-402 20
MAGE
Simple arithmetic average of the “amplitudes” of all glycaemic excursions
Amplitudes can be estimated by the magnitude of either the upward shifts
or the downward shifts of each excursion
• Upward excursion: MAGE+
• Inward excursion: MAGE-
• Average excursion: MAGE.avge
Baghurst PA. Diabetes Technol Ther 2011;13:296-301 Example of final MAGE calculation
2 main advantages of MAGE
• The parameter is not dependent on the mean
glucose value
• It is designed to quantitate major glucose swings
and exclude minor ones

Conclusion
Addition of DPP-4 inhibitor significantly reduced glycaemic variability with
no difference between the two drugs
However vildagliptin induced better circadian glycaemic control than
sitagliptin with a significant decrease on over all hyperglycaemia
Time takes to stay in ideal blood glucose range

Objective:
Evaluate the effects of two dipeptidyl peptidase-IV (DPP-4) inhibitors,
sitagliptin and vildagliptin, known to have different efficacy on :
Mean amplitude of glycemic excursions (MAGE)
Oxidative stress
Systemic inflammatory markers in patients with type 2 diabetes
Rizzo MR et al. Diabetes Care 2012;35:2076-82 25
Design and Methods:
Prospective, randomized, open-label (PROBE) design (parallel group
with a blinded end point) in 90 patients with T2DM inadequately
controlled by metformin
The study assigned 45 patients to receive sitagliptin (100 mg once daily;
sitagliptin group) and 45 patients to receive vildagliptin (50 mg twice
daily; vildagliptin group) for 12 weeks
MAGE, evaluated during 48 h of continuous subcutaneous glucose
monitoring (CSGM), allowed an assessment of daily glucose fluctuations
at baseline and after 12 weeks in all patients
Assessment of oxidative stress (nitrotyrosine) and systemic levels of
inflammatory markers interleukin (IL)-6 and IL-18 were performed at
baseline and after 12 weeks in all patients
Rizzo MR et al. Diabetes Care 2012;35:2076-82 26
Vildagliptin, compared to Sitagliptin, is significantly better in MAGE reduction,
hence better in reduction of oxidative stress
Rizzo MR et al. Diabetes Care 2012;35:2076-82
Conclusion:
MAGE reduction is associated with reduction of oxidative stress and
markers of systemic inflammation in type 2 diabetic patients.
These effects were greater in the vildagliptin group than in the sitagliptin
group
Rizzo MR et al. Diabetes Care 2012;35:2076-82 28
Vildagliptin and GLP-1 inactivation
• Vildagliptin 50 mg once daily: blocks GLP-1 inactivation during the
three daily meals, resulting in reduced PPG and its associated
reduction in FPG1
• Vildagliptin 50 mg twice daily: blocks GLP-1 inactivation over
24 hours, providing an additional reduction in FPG due to a direct
effect on overnight HGP1
• In moderate and severe renal impairment (RI):
‒ vildagliptin 50 mg once daily expected to block GLP-1 inactivation over
24 hours2
• reductions in HbA1c in patients with RI given qd dose comparable with bid
dose in similar patient population with preserved renal function and similar
baseline HbA1c2

EDGE study Conclusion
In conclusion, EDGE demonstrated in a real-life setting
that T2DM patients in whom second-line oral glucose-
lowering therapy is initiated:
• vildagliptin can succeed in lowering HbA1c to < 7%,
(without weight gain, hypoglycaemia or peripheral
oedema) in a higher proportion than comparator OADs
• No differences in the reported number of AEs or SAEs
between Vildagliptin and comparator OAD.
• This information is consistent with data from RCTs with
vildagliptin

GUARD was a large prospective study assessing vildagliptin with/without
metformin in a real-world setting: more than 19,000 patients with T2DM were
pooled across Asia, Middle East, Central America and Africa
Vildagliptin with/without metformin was associated with statistically significant
and clinically relevant HbA1c reductions from baseline
This effect was observed irrespective of patient age or obesity status and was
seen across baseline HbA1c categories
Vildagliptin without/without metformin was generally well tolerated
Overall, the findings from the real-world GUARD study are generally consistent
with other real-world studies and interventional controlled clinical trials with
vildagliptin with/without metformin

Is There Evidence of Any Safety Differences Among
DPP-4 inhibitors in Treatment of People with T2DM and
CKD?
• DPP-4 inhibitors have been shown to be associated with no further decline in
estimated glomerular filtration rate (eGFR) when treating patients with CKD
• Vildagliptin 50 mg efficacy is maintained when the frequency of dosing is reduced
from twice daily in patients with normal renal function to once daily in patients
with moderate or severe RI
• The dose adjustments thus require regular monitoring of renal function, which is
also good clinical practice because in these patients it is important to closely
monitor renal disease progression.
• Other than the specifications for modifications in dose or dose frequency, there
appears to be no difference between each DPP-4 inhibitor with respect to their
safety and tolerability in patients with T2DM and CKD
• Study in which vildagliptin was dosed at either 50 mg once or twice daily in
patients with ESRD, both dosing regimens were well tolerated, with no clinically
important differences noted between doses with respect to adverse events. Thus,
any concern that accumulation of vildagliptin (or its renally excreted metabolites)
results in an increase in renal or other toxicities is not supported by data.

Vildagliptin data in renal impairment
UACR=urinary albumin-to-creatinine ratio ; RI = renal impairment
The prescribing information may vary from country to country. Before prescribing, please refer to your local country’s full prescribing information for
locally approved indications and full details.. In general, no dose adjustment is required for vildagliptin in patients with mild renal impairment (creatinine
clearance ≥ 50 ml/min). In patients with moderate or severe renal impairment or with end-stage renal disease (ESRD), the recommended dose of
vildagliptin is 50 mg once daily. There is limited experience in patients with ESRD on haemodialysis and hence should be used with caution in these
patients

Stages of chronic kidney disease / guideline
Chronic kidney disease is defined as either kidney damage or GFR <60 mL/min/1.73m2 for
≥3 months. Kidney damage is defined as pathologic abnormalities or markers of damage, including
abnormalities in blood or urine tests or imaging studies.
Stage DescriptionCurrently accepted values
GFR (mL/min/1.73m2)^
1 Kidney damage with normal or ↑ GFR ≥90
2 Kidney damage with mild ↓ GFR 60–89

Aim: To assess the effects of vildagliptin 50 mg qd in patients with advanced type 2 diabetes and
moderate or severe RI whose hyperglycemia was not adequately controlled with insulin alone or in
combination with an oral anti-diabetic agent at baseline.
Study design: This was a 24-week, multicenter, randomized, double-blind, parallel group, placebo-
controlled trial of vildagliptin in adult patients (age 18–85 years) with T2DM and moderate or severe RI
(eGFR by the MDRD formula ≥ 30 to <50 and <30 ml/min/1.73 m2, respectively).

Conclusions
• Treatment with vildagliptin (50 mg qd) added to ongoing anti-diabetic therapy was
well-tolerated, with a safety profile comparable to placebo.
• In patients with moderate or severe RI, vildagliptin added to current therapy elicited
robust improvements in glycemic control with HbA1c reductions of ∼0.7% (from
baseline 7.9% in moderate RI) and ∼0.9% (from baseline of 7.7% in severe RI).
• It may be concluded that vildagliptin treatment is well-tolerated and effective in
patients with T2DM and moderate or severe RI and did not cause deterioration of
renal function.

and Severe Renal Disease
● Aim: To assess long-term safety and efficacy of vildagliptin 50 mg qd in patients with T2DM and
moderate or severe RI.
● Design: This was a long-term extension of a randomized, double-blind, parallel-group, placebo-
controlled 24-week clinical trial. Adult patients (age 18–85 years) having T2DM and moderate or
severe RI (eGFR by the MDRD formula ≥ 30 to <50 mL/min/1.73 m2 and <30 mL/min/1.73 m2,
respectively) were included in this study.

Incidence of Hypoglycemia in T2DM Patient with
Moderate and severe RI receiving Vildagliptin
There was a slightly higher incidence of mild hypoglycaemia in patients with moderate RI treated with
vildagliptin than with placebo.
Rates of hypoglycaemia in patients with severe RI were similar across treatment groups.
Very few events of severe hypoglycaemia, and more with placebo than vildagliptin.
incidence of hypoglycaemia with vildagliptin in the present study (∼26% in patients with moderate RI and
∼18% in those with severe RI) appears to be lower than that expected (≥50%) in patients with
longstanding T2DM and low baseline A1C (∼7.6%).

In patients with T2DM and moderate or severe Renal
Impairment, vildagliptin added to ongoing antidiabetic therapy
had a safety profile similar to placebo during 1-year
observation. Furthermore, relative to placebo, a clinically
significant decrease in A1C was maintained throughout 1-year
treatment with vildagliptin.

Conclusions
This is the largest long-term study with a DPP-4 inhibitor in patients with T2DM and
moderate or severe RI.
Vildagliptin maintained the robust efficacy throughout 52 weeks with HbA1c
reductions of ~0.6% and ~0.8% from baselines of 7.8% and 7.7% in moderate and
severe RI, respectively.
Safety profile of vildagliptin 50 mg qd was similar to placebo when added to anti-
diabetic therapy during 1-year observation.
The incidence of hypoglycemia with vildagliptin (26% in moderate and 19% severe RI
groups) was lower than expected in patients with longstanding T2DM receiving
insulin ± OADs and achieving significantly tighter glycemic control at low baseline
HbA1c (~7.6%). The risk of severe hypoglycemia was very low.
These data support the long-term safety and efficacy of vildagliptin 50 mg qd added
to ongoing anti-diabetic therapy in patients with moderate or severe RI.
