NCT01822548

Brief Summary

The purpose of this study is to evaluate the effect of Dipeptidyl peptidase (DPP) -IV inhibitor Vildagliptin vs. Glibenclamide on circulating endothelial progenitor cells (EPCs) number in type 2 diabetes patients in metformin failure. Subjects will be followed for 12 months after randomization.

Outcome Measures

Primary Outcomes (1)

  • Absolute Change in the Endothelial Progenitor Cell (EPC) Number

    The study primary endpoint was the change from baseline values of the EPC number in the Vildagliptin vs Glibenclamide arm at 4 and 12 months.

    V0, V2 (month 4), V4 (12 month)

Secondary Outcomes (1)

  • Absolute Change in HbA1C Compared to Baseline

    V0 (randomization), V2 (month4), V4 (month 12).

Eligibility Criteria

Age35 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age equal or above 35 years;
  • Diagnosis of type 2 diabetes mellitus as defined by the American Diabetes Association , with at least one year of disease duration at the time of the screening visit;
  • Blood glucose lowering treatment with Metformin alone (monotherapy) at a stable dose of at least 1.5 g/day (or maximum tolerated dose) in the 3 months prior to the screening visit;
  • Insufficient metabolic control as defined by recent (last six months) HbA1c ≥ 7% in any peripheral laboratory and confirmed at the time of the screening;

You may not qualify if:

  • Written informed consent to participate to the study.
  • Age below 35 years
  • Type 1 diabetes or other causes of diabetes (pancreatectomy, gestational diabetes, etc.)
  • HbA1c \< 7% or ≥ 9% at the screening visit
  • Treatment with any blood glucose lowering treatment other than Metformin in the six months before screening visit
  • BMI \< 20 or ≥ 40 kg/m2, or current/ past history of clinically-relevant eating disorders (including -but no limited to- nervous anorexia, bulimia, binge-eating disorders, etc.)
  • Significant progression of diabetic macro-angiopathy or cardiovascular disease in the six months prior to study visit
  • Significant progression of diabetic micro-angiopathy in the six months prior to study visit
  • Organ failure or other severe diseases limiting life expectancy;
  • Beginning, in the three months before screening visit, of any kind of drug which can modify glycemic levels (beta-blockers, diuretics…), or acute disease (acute infection, urinary tract infection…) in three months before screening visit
  • History of inflammatory/infective/autoimmune chronic disease
  • History of unexplained pancreatitis, chronic pancreatitis, pancreatectomy, gastric surgery, inflammatory bowel disease;
  • Any clinically significant abnormality identified on physical examination, laboratory tests, ECG or vital signs at screening that in the judgment of the investigator would preclude safe completion of the study;
  • Uncontrolled or inadequately controlled hypertension at screening (Systolic Blood Pressure (SBP)\>190 or Diastolic Blood Pressure (DBP) \>100 mmHg)
  • Ongoing pregnancy or absence of effective contraception in women with childbearing potential
  • +10 more criteria
