Long-Term Effects of Insulin Plus Metformin Regimens on the Overall and Postprandial Glycemic Control of Patients With Type 2 Diabetes

Summary

The primary objective of this study is to show that a prandial insulin regimen, consisting of premeal insulin lispro "mid mixture" (or a combined regimen of insulin lispro "mid mixture" and insulin lispro "low mixture") plus metformin will result in significantly better overall glycemic control (lower HbA1c) at endpoint than once-daily insulin glargine plus metformin. Insulin lispro "mid mixture" consists of 50% insulin lispro and 50% NPL. Insulin lispro "low mixture" consists of 25% insulin lispro and 75% NPL. In a substudy of approximately 60 patients, additional data will be collected on markers associated with risk of atherosclerosis or cardiovascular disease in the context of a controlled, outpatient, high-fat test meal.
