Arm && Interventions

Group	Intervention	Description
Insulin Glargine (with Insulin Lispro)	Insulin Lispro	Insulin glargine once daily SC injection at bedtime. Insulin lispro given SC prandially or as a bolus as required
Insulin peglispro (LY2605541, with Insulin Lispro)	Insulin Lispro	Insulin peglispro (LY2605541) once daily subcutaneous (SC) injection at bedtime. Insulin lispro given SC prandially or as bolus as required
Insulin peglispro (LY2605541, with Insulin Lispro)	Insulin Peglispro	Insulin peglispro (LY2605541) once daily subcutaneous (SC) injection at bedtime. Insulin lispro given SC prandially or as bolus as required
Insulin Glargine (with Insulin Lispro)	Insulin Glargine	Insulin glargine once daily SC injection at bedtime. Insulin lispro given SC prandially or as a bolus as required

Primary Outcome Measures

Name	Time	Method
Pharmacodynamics (PD): Plasma Glucose Area Under the Concentration Curve Zero Through 5 Hours (AUC 0-5h), Above Pre Meal Baseline for Insulin Lispro	Day 30, 31, 32, 33, 34, pre-breakfast and10,20,30,40,50,60,90,120,150,180,210,240,270, 300 minutes (5 hours) post-breakfast	To quantitate the pharmacodynamic (PD) effect of a range of prandial insulin lispro doses after treatment with insulin peglispro (LY2605541) compared to insulin glargine during a meal tolerance test (MTT), with sequenced doses of insulin lispro ranging from 25% to 150% of each participant's normal dose. Data presented as hours times milligrams per deciliter (mg\*h/dL)

Secondary Outcome Measures

Name	Time	Method
Pharmacokinetics (PK): Under the Concentration Curve Zero Through 5 Hours (AUC 0-5h) for Prandial Insulin Lispro	Day 29: Pre-breakfast, and 15, 30, 45, 60, 90, 120, 150,180,210,270, and 300 minutes (5 hours) post-breakfast	Abbreviation for hours times picomol per liter (pmol\*h/L)
Appetite and Satiety Ratings, as Measured Using Visual Analog Scale (VAS) on Day 29	Day 29:Upon waking, pre-breakfast, 1 hour (hr), 2 hr, 3 hr, 4 hr and 5 hr post breakfast	VAS was scored from 0 - 100 millimeters (mm) as a perception of appetite and satiety (Flint et al. 2000), 0 being not hungry at all or nothing at all and 100 being extremely hungry and extremely large amount.; The questions are abbreviated in table from: How hungry do you feel right now? to Hunger and How much food do you think you could eat right now? to Food amount.; Day 29 and cumulative insulin lispro doses of 25%, 50%, 75%, 100% and 150 % of normal insulin lispro dose included.Scores were averaged will be presented and calculated by a sum of the scores dividing by the total by the number of scores reported for timepoints and reported in millimeters.
Pharmacodynamics (PD): Average Glucose Infusion Rate From Euglycemic 2-step Hyperinsulinemic Clamp (M-value)	Day 35, last 60 minutes of euglycemic 2-step hyperinsulinemic clamp	Abbreviation for micro mole per kilogram per minute (µmol/kg/min). Both arms received insulin lispro in addition to their respective study drug. During the euglycemic 2-step hyperinsulinemic clamp, both low and high insulin was infused sequentially during the same procedure. The 2-step clamp procedure allowed insulin sensitivity to be measured in participants and uses a lower dose of insulin of which the effect is largely on the liver and a high dose of insulin at which the effect has reached 100% on liver and effects are largely on glucose uptake in peripheral tissues. Measurements for average glucose infusion rate are collected for both steps (low and high) of the clamp procedure.
Pharmacokinetics (PK): Area Under the Concentration Curve From Time Zero to Last Time (AUC [0 Tlast]) for Paracetamol	Day 29: Pre-breakfast, and 15, 30, 45, 60, 90, 120, 150,180,210,270, and 300 minutes (5 hours) post-breakfast
Pharmacodynamics (PD): Area Under the Concentration Zero Through 5 Hours (AUC 0-5h) for Triglycerides	Day 29, predose and 15, 30, 45, 60, 90, 120, 150,180,210,270, and 300 minutes (5 hours) post-breakfast
Pharmacokinetics (PK): Area Under the Concentration Curve (AUC) for Insulin Lispro During Clamp	Day 35, insulin clearance during lispro infusion (dosing=infusion)	During the euglycemic 2-step hyperinsulinemic clamp, both low and high insulin was infused sequentially during the same procedure. The 2-step clamp procedure allowed insulin sensitivity to be measured in participants and uses a lower dose of insulin (Low) of which the effect is largely on the liver and a high dose of insulin (high) at which the effect has reached 100% on liver and effects are largely on glucose uptake in peripheral tissues. AUC is taking during infusion for this outcome measure.
