  Purpose

We performed a prospective, randomized, multicenter trial to assess the efficacy and safety of combined treatment with mitiglinide and metformin for patients with type 2 diabetes who show inadequate glycemic control with metformin monotherapy. Subjects with HbA1c >7.0% after an 8-week metformin run-in phase were randomized to a 16-week trial phase with metformin plus mitiglinide (Met+Mit) or metformin plus placebo (Met).

Primary Outcome Measures:
  • the change in HbA1c from randomization to endpoint [ Time Frame: 16 weeks after radomization ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • the proportion of subjects with HbA1c <7% after 16 weeks of treatment and the change in FPG and 2-hr postprandial glucose (PPG) from baseline [ Time Frame: 16 weeks after radomization ] [ Designated as safety issue: No ]

Enrollment: 145
Study Start Date: August 2006

Arms Assigned Interventions
Active Comparator: Metformin+Mitiglinide
mitiglinide 10 mg three times a day added to metformin 500 mg three times a day
Drug: Mitiglinide

mitiglinide 10 mg three times a day added to metformin 500 mg three times a day

for 16 weeks

Placebo Comparator: Metformin+Placebo
placebo three times a day added to metformin 500 mg three times a day
Drug: Placebo
placebo three times a day added to metformin 500 mg three times a day for 16 weeks

Detailed Description:

This was a 16-week, randomized, double-blind study for comparing metformin plus mitiglinide (Met+Mit) versus metformin plus placebo (Met+Pcb). An 8-week metformin run-in phase (500 mg twice a day for the first 4 weeks and 500 mg three times a day for the following 4 weeks) was followed by a 16-week trial phase (mitiglinide 10 mg or placebo three times a day added to metformin 500 mg three times a day). The subjects with an HbA1c >7.0% at the end of the metformin run-in phase were randomized to a Met+Mit group or a Met+Pcb group of the trial phase.
