  • To investigate the efficacy of insulin glargine (in terms of change in A1c from baseline to endpoint A1c < 7%)


  • To investigate the safety of insulin glargine (in terms of hypoglycaemia, including symptomatic, non-symptomatic and nocturnal hypoglycaemia)
  • To investigate whether beta cell function is preserved if this therapy is initiated before 2nd OAD (oral anti-diabetic drug) failure
