Insulin Lispro 6 Days Versus Insulin Aspart 6 Days in Pump Use

A Double-Blind, Randomized, Crossover Trial of CSII Reservoir In-use Comparing Insulin Lispro Formulation to Insulin Aspart in Patients With Type 1 Diabetes Mellitus

Patients will continue to use their current insulin pump for this study. Patients will receive insulin lispro and insulin aspart during this study. One medication will be taken for 12 weeks and then the other medication for 12 weeks. Neither the patient nor the study doctor will know which medication is being taken at any time. The order in which the two medications are taken will be determined by chance.

Outcome Measure	Measure Description	Time Frame
Change From Baseline to 12 Weeks for Daily Insulin Dose (Total, Basal, and Bolus)		Baseline, endpoint for each 12-week treatment period
Percentage of Participants Having a Hyperglycemic Episode	A hyperglycemic episode was defined as an event with (1) a measured blood glucose concentration >250 milligrams per deciliter (mg/dL) (13.9 millimoles per liter [mmol/L]) and ≥3 hours after eating, or (2) a measured blood glucose concentration >300 mg/dL (16.7 mmol/L) and <3 hours after eating	Days 1-6 for each reservoir cycle throughout each 12-week treatment period
Hyperglycemic Episode Rate Per 30 Days	Hyperglycemia was defined as an episode with (1) a measured blood glucose concentration >250 milligrams per deciliter [mg/dL] (13.9 millimoles per liter [mmol/L]) and ≥3 hours after eating, or (2) a measured blood glucose concentration >300 mg/dL (16.7 mmol/L) and <3 hours after eating.

When either a reservoir change or an infusion set change was reported, participants were questioned whether the change occurred early (prior to 6 days). If he/she responded 'yes', then the reported change was recorded as a premature change.	Days 1-6 for each reservoir cycle throughout each 12-week treatment period

When either a reservoir change or an infusion set change was reported, participants were questioned whether the change occurred early (prior to 6 days). If he/she responded 'yes', then the reported change was recorded as a premature change.	Days 1-6 for each reservoir cycle throughout each 12-week treatment period
Percentage of Participants Having a Hypoglycemic Episode	A Documented Hypoglycemic Episode is defined as an event which is associated with a documented blood glucose (BG) concentration of <= 70 mg/dL (3.9 mmol/L). All Reported Hypoglycemic Episodes are defined as an event which is associated with; reported signs and symptoms of hypoglycemia, and/or; a documented blood glucose (BG) concentration of <= 70 mg/dL (3.9 mmol/L)	All days for each reservoir cycle throughout each 12-week treatment period
Hypoglycemic Episode Rate Per 30 Days	All Reported Hypoglycemic Episodes are defined as an event which is associated with; reported signs and symptoms of hypoglycemia, and/or; a documented blood glucose (BG) concentration of <= 70 mg/dL (3.9 mmol/L)	All days for each reservoir cycle throughout each 12-week treatment period
Change From Baseline to 12 Week Endpoint for Each Treatment in Weight		Baseline, endpoint for each 12-week treatment period
Change From Baseline to 12 Weeks Endpoint for Each Treatment in Blood Pressure		Baseline, endpoint for each 12-week treatment period
