Further study details as provided by National Cheng-Kung University Hospital:

Primary Outcome Measures:
  • change of HbA1c at 12 weeks
  • Change of fasting plasma glucose (FPG) at 12 weeks
  • Change of postprandial plasma glucose (PPG) at 12 weeks

Secondary Outcome Measures:
  • Safety parameters including adverse events such as hypoglycemia
  • change of liver and renal function test

Estimated Enrollment: 50
Study Start Date: July 2006
Detailed Description:
This study is designed to evaluate the efficacy and safety of a new-brand of repaglinide X® in comparison to Novonorm® for the treatment of type 2 diabetes mellitus patients. Mentally competent patients with age of 30 to 75 years old in Taiwan of either sex with type 2 diabetes mellitus will be included. All eligible subjects will be randomized into treatment groups in 1:1 ratio. The treatment will consist of either X® or Novonorm® tid before meal for 12 weeks of treatment. The primary endpoints include the net change of HbA!c, fasting plasma glucose(FPG)and postprandial plasma glucose(PPG)at the end of 12th week evaluation compared to the baseline visit. Also, safety profiles including adverse event (such as hypoglycemia) incidences, blood pressure, liver, kidney function test will be monitored.

Ages Eligible for Study:   30 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients have type 2 diabetes mellitus diagnosed after 25 years of age
  • Patients have been in poor glycemic control by diet or exercise for at least 1 month or by a stable dose of metformin for at least 3 months before study; poor glycemic control is defined as: Glycosylated hemoglobin A1c (HbA1c) 7.1-11.0%
  • Patients have signed the written informed consent form

Exclusion Criteria:

  • Patients with on-going inflammatory bowel disease, colonic ulceration, partial intestinal obstruction
  • Patients are predisposed to intestinal obstruction
  • Patients with chronic intestinal diseases related to marked disorders of digestion or absorption
  • Patients with clinically significant medical conditions that may deteriorate clinically due to gastrointestinal gas increase
  • Patients with a history of lactic acidosis
  • Patients with a history of allergic to repaglinide
  • Patients took any hypoglycemic agent except for metformin within 3 months before study
  • Patients participated investigational drug trial within 1 month before entering this study
  • Patients with any other serious diseases considered by the investigator not in the condition to enter the trial
