Primary Outcome Measures:
  • Percentage of participants with a decrease in HbA1c (glycosylated haemoglobin A1c) of at least 1% [ Time Frame: month 12 ]
  • Percentage of participants reaching the treatment target of a HbA1c (glycosylated haemoglobin A1c) decrease of at least 1% [ Time Frame: month 12 ]

Secondary Outcome Measures:
  • HbA1c [ Time Frame: month 12 ]
  • Fasting blood glucose (FBG) [ Time Frame: month 12 ]
  • Incidence of serious adverse events (SAEs) [ Time Frame: months 0-12 ]
  • Incidence of adverse drug reactions (ADRs) [ Time Frame: months 0-12 ]
  • Frequency of hypoglycaemic episodes (frequency of episodes with low blood sugar) [ Time Frame: months 0-12 ]

Enrollment: 254
Study Start Date: February 2011
Study Completion Date: March 2013
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
