About

The purpose of this study is to examine the efficacy and safety of insulin lispro protamine suspension (ILPS) as compared to insulin detemir as basal insulin combined with mealtime insulin therapy in patients with type 1 diabetes. A gatekeeper strategy will be employed for sequentially testing the secondary objectives.

Full description

Phase 3b, randomized, multicenter, multinational, open-label, two-arm, active control, parallel study to determine safety, efficacy, and noninferiority of basal analog insulin lispro protamine suspension (ILPS, also referred to as NPL [neutral protamine Hagedorn]), injected two times a day, compared with basal analog insulin detemir, injected two times a day, as measured by change in hemoglobin A1c (HbA1c) from baseline (Visit 2) to 32 weeks in adult patients with type 1 diabetes when used in combination with bolus insulin lispro, injected three times a day.
