A study in people with type 1 diabetes to determine how well a meal-time insulin, LY900014, controls diabetes compared to Humalog (insulin lispro) when both are used along with a long-acting insulin.

A Prospective, Randomized, Double-Blind Comparison of LY900014 to Insulin Lispro with an Open-Label Postprandial LY900014 Treatment Group, in Combination with Insulin Glargine or Insulin Degludec, in Adults with Type 1 Diabetes - PRONTO-T1D

Design outcomes

Primary

MeasureTime frame
Main Objective: To test the hypothesis that LY900014 is noninferior to insulin lispro on glycemic control (non-inferiority margin [NIM]=0.4% for hemoglobin A1c [HbA1c]) in patients with T1D, when administered as prandial insulin (0 to 2 minutes prior to the meal), in combination with basal insulin glargine or insulin degludec for 26 weeks ;Secondary Objective: To test the hypothesis that LY900014 is superior to insulin lispro in controlling 1-hour PPG excursions, when administered as prandial insulin. To test the hypothesis that LY900014 is superior to insulin lispro in controlling 2-hour PPG excursions, when administered as prandial insulin.  To test the hypothesis that LY900014 is superior to insulin lispro on improving glycemic control (HbA1c) when administered as prandial insulin. To test the hypothesis that LY900014 administered as postprandial insulin 20 minutes after the start of a meal, (LY900014+20), is noninferior to insulin lispro, administered as prandial insulin, on glycemic control (NIM=0.4% for HbA1c);Primary end point(s): Change in HbA1c;Timepoint(s) of evaluation of this end point: 26 weeks

Secondary

MeasureTime frame
Secondary end point(s): 1.       Difference between LY900014 and insulin lispro in the 1-hour PPG excursion (serum glucose measured 1 hour after the start of the meal minus fasting serum glucose) from a MMTT. 2.       Difference between LY900014 and insulin lispro in the 2-hour PPG excursion (serum glucose measured 2 hours after the start of the meal minus fasting serum glucose) from an MMTT. 3.       Difference between LY900014 and insulin lispro in change from baseline in HbA1c  4.       Difference between LY900014+20 and insulin lispro in change from baseline in HbA1c ;Timepoint(s) of evaluation of this end point: 1. 26 weeks 2. 26 weeks 3. 26 weeks 4. 26 weeks
