This study will compare insulin lispro low mixture and insulin glargine in combination with the patient’s oral diabetes medicines for their ability to control blood sugar in patients with type 2 diabetes and compare insulin lispro LM to insulin glargine with regard to the length of time that the overall blood sugar can be controlled.

This study will also determine whether the safety of insulin lispro LM and any side effects that might be associated with it are different from those observed with insulin glargine in combination with the patient’s oral diabetes medications.

The addendum study will compare how different insulin treatments work to control blood sugar in patients whose diabetes could not be controlled by either insulin lispro LM or insulin glargine.

Further Details

Primary Outcome Measures (main trial):

  • Initiation phase: Comparison of endpoint A1C after 6 months of starter insulin therapy with either insulin lispro low mixture [LM] twice-daily or insulin glargine.
  • Maintenance phase: Comparison of the duration of time that each starter insulin regimen is able to maintain A1C at goal.

Secondary Outcome Measures (main trial): Comparison of safety and efficacy of two starter insulin regimens during the initiation phase and maintenance phase with respect to:

  • Percentage of patients with A1C < or = 7.0% and A1C < or = 6.5%
  • Change in A1C
  • A1C at each visit
  • Seven point blood glucose profiles and excursions after meals 1,5 Anhydroglucitol
  • Absolute and incremental weight change
  • Insulin dose
  • Incidence as well as rate of self-reported hypoglycemic episodes
  • Comparison of rates of increase in A1C of two starter insulin regimens during the maintenance phase will also be evaluated
  • The baseline and endpoint characteristics of the patient populations that fail to achieve and/or maintain control will also be compared with those that succeeded in achieving and/or maintaining control

Study Start

December 2005; Expected completion: June 2010
