insulin injection pens; comply with their prescribed diet, exercise, and medication
regimen; perform self-monitoring of blood glucose; and use the patient diary as
required for this protocol.

Summary
Brief 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.
