Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Have type 2 diabetes (World Health Organization \[WHO\] classification
* Have used one or more of the following oral anti-hyperglycemic medications-metformin or second-generation sulfonylurea (for example, glibenclamide, glyburide, glipizide, gliclazide, glimepiride) alone or in combination with one or two insulin injections per day for at least 3 months immediately prior to entering the study. Patients using more than 2 insulin injections per day or subcutaneous insulin infusion prior to the study will not be eligible to participate.
* Have a hemoglobin A1c between 6.5% and 11%, inclusive, according to the central laboratory at Visit 1.
* Have clinically acceptable LDL-C, in the investigator's opinion, at Visit 1.
* As determined by the investigator, are capable and willing to learn how to use the 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.

Exclusion Criteria

* Have hypersensitivity to metformin or a known allergy to metformin hydrochloride, insulin lispro MM, insulin lispro LM, or insulin glargine, or excipients contained in these products.
* Have known metabolic or lactic acidosis.
* Have a history of renal transplantation or are currently receiving renal dialysis or have serum creatinine greater than or equal to 135 micromol/L (1.5 mg/dL) for males and greater than or equal to 110 micromol/L (1.2 mg/dL) for females.
* Have cardiac disease with functional status that is Class III or IV
* Have obvious clinical signs or symptoms of liver disease, acute or chronic hepatitis, or alanine transaminase (ALT) greater than three times the upper limit of the reference range as defined by the central laboratory.
