Efficacy and Safety of Vildagliptin as add-on Therapy to Metformin in Patients With Type 2 Diabetes

February 23, 2017 updated by: Novartis Pharmaceuticals

A Multicenter, Double-Blind, Randomized, Parallel-Group Study to Compare the Effect of 12 Weeks Treatment With LAF237 50 mg Bid to Placebo as Add-On Therapy in Patients With Type 2 Diabetes Inadequately Controlled With Metformin Monotherapy

The purpose of the study is to evaluate the efficacy and safety of vildagliptin 50 mg bid as an add-on therapy to metformin in Japanese patients with T2DM. This study is being conducted to support registration of the fixed-dose combination of vildagliptin and metformin for the treatment of Type 2 diabetes mellitus (T2DM) in Japan.

Drug: Vildagliptin
vildagliptin 50 mg twice daily
Other Names:

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from baseline in glycosylated hemoglobin (HbA1c) at 12 weeks between treatment groups
Time Frame: Baseline to 12 weeks
HbA1c will be performed on a blood sample obtained by study personnel and measured by high-performance liquid chromatography (HPLC) performed at a central laboratory.
Baseline to 12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from baseline in HbA1c at 12 weeks within subgroups of metformin doses
Time Frame: Baseline to 12 weeks
HbA1c will be performed on a blood sample obtained by study personnel and measured by high-performance liquid chromatography (HPLC) performed at a central laboratory.
Baseline to 12 weeks
Change from baseline in Fasting plasma glucose (FPG) at 12 weeks
Time Frame: Baseline to 12 weeks
FPG will be performed on a blood sample obtained by study personnel and analyzed at a central laboratory.
Baseline to 12 weeks
Percentage of patients meeting Responder rates in HbA1c
Time Frame: 12 weeks

Responder rates will be categorized by predefined HbA1c value at 12 weeks :

  • Endpoint HbA1c ≤ 6.5%
  • Endpoint HbA1c ≤ 7%
  • Endpoint HbA1c ≤ 7% in patients with baseline HbA1c ≤ 8%
12 weeks
Number of patients with adverse events (including hypoglycemia), serious adverse events and death
Time Frame: 12 weeks
The occurrence of adverse events will be sought by non-directive questioning of the patient at each visit. Adverse events are defined as appearance or worsening of any undesirable symptom, sign (including an abnormal laboratory finding), or medical conditions. Serious adverse events are any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgment of investigators represent significant hazards.
