Arm && Interventions

Group	Intervention	Description
Insulin Lispro Mix50	Insulin Lispro Mix50	Insulin Lispro Mix50 administered SC using prefilled pen twice daily for 26 weeks.
Insulin Lispro Mix25	Insulin Lispro Mix25	Insulin Lispro Mix25 administered subcutaneously (SC) using prefilled pen twice daily for 26 weeks.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Hemoglobin A1c (HbA1c) at Week 26	Baseline, Week 26	HbA1c is the glycosylated fraction of hemoglobin A which provides an estimate of a participant's blood sugar control over a 6- to 12-week period. Least Squares (LS) means were calculated by Mixed Models Repeated Measurements (MMRM) analysis using change from baseline in HbA1c at all post baseline measurement as dependent variables, treatment, blood glucose (BG) excursion, country, visit and treatment-by-visit interaction as fixed effects, baseline HbA1c value as a covariate and participants as a random effect.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in 1,5-Anhydroglucitol (1,5-AG) at Week 26	Baseline, Week 26	LS means were calculated by MMRM analysis using change from baseline in 1.5-AG variables at all post baseline measurement as dependent variables, treatment, country, BG excursion, visit and treatment-by-visit interaction as fixed effects, baseline SMBG variable value as a covariate and participants as a random effect.
Percentage of Participants Achieving HbA1c of <7.0% or ≤6.5% Baseline Through Week 26	Baseline through Week 26	HbA1c is the glycosylated fraction of hemoglobin A which provides an estimate of a participant's blood sugar control over a 6- to 12-week period. The percentage of participants with HbA1c \<7.0% or HbA1c ≤6.5% is calculated as the number of participants with an HbA1c level of the cut-off value (\<7.0% or ≤6.5%) divided by the number of participants treated, then multiplied by 100.
Number of Hypoglycemic Events Baseline Through Week 26 (Incidence)	Baseline through Week 26	A hypoglycemic event is defined as any time a participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia, or has a BG concentration of ≤ 70milligrams/deciliter \[mg/dL (3.9 mmol/L)\], even if it was not associated with signs, symptoms, or treatment consistent with current guidelines \[American Diabetes Association (ADA) 2005\].
Insulin Dose at Week 26	Week 26	Insulin dose is the total daily dose including basal and prandial doses.
Change From Baseline in Fasting Blood Glucose (FBG) at Week 26	Baseline, Week 26	LS means were calculated by MMRM analysis using change from baseline in FBG variables at all post baseline measurement as dependent variables, treatment, country, BG excursion, visit and treatment-by-visit interaction as fixed effects, baseline self-monitoring blood glucose (SMBG) variable value as a covariate and participants as a random effect.
Change From Baseline in Body Weight at Week 26	Baseline, Week 26	LS means were calculated by MMRM analysis using change from baseline in weight variables at all post baseline measurement as dependent variables, treatment, country, BG excursion, visit and treatment-by-visit interaction as fixed effects, baseline SMBG variable value as a covariate and participants as a random effect.
