A Study Comparing Insulin Peglispro With Insulin Glargine as Basal Insulin Treatment

The purpose of this study is to compare insulin peglispro (LY2605541) to insulin glargine in Asian insulin naïve participants who have been treated with oral anti hyperglycemia medications. Participants will receive 26 weeks of treatment.

* Body mass index (BMI) ≤35.0 kilogram per square meter (kg/m\^2)
* Inject insulin with a pre-filled insulin pen and perform Self-Monitored Blood Glucose (SMBG)
* Record keeping as required by this protocol
* Women of childbearing potential are not breastfeeding, have a negative pregnancy test at screening, do not plan to become pregnant during the study, have practiced reliable birth control during the study and 2 weeks following the last dose of investigational product

Exclusion Criteria:

* Have used insulin therapy (outside of pregnancy) anytime in the past 2 years, except for short term treatment of acute conditions
* Have been treated with rosiglitazone, pramlintide, glucagon-like peptide-1 (GLP-1) receptor agonist within 3 months prior to screening
* Are using or have used any of the following lipid-lowering medications: niacin preparations as a lipid-lowering medication and/or bile acid sequestrants within 90 days prior to screening

* Have a history of renal transplantation, or are currently receiving renal dialysis or have serum creatinine ≥2.0 milligram per deciliter (mg/dL) (177 micromole per liter \[μmol/L\]). Participants taking metformin should not exceed the creatinine level specified in the local label
* Have obvious clinical signs or symptoms of liver disease (excluding non-alcoholic fatty liver disease \[NAFLD\]), acute or any chronic hepatitis, non alcoholic steatohepatitis (NASH), or elevated liver enzyme measurements
* Have had a blood transfusion or severe blood loss within 3 months prior to screening or have known hemoglobinopathy, hemolytic anemia or sickle cell anemia, or any other traits of hemoglobin abnormalities known to interfere with the measurement of HbA1c
* Have active or untreated cancer, have been in remission from clinically significant cancer(other than basal cell or squamous cell skin cancer) for less than 5 years, or are at increased risk for developing cancer or a recurrence of cancer in the opinion of the investigator
* Have known hypersensitivity or allergy to any of LY2605541 and insulin glargine or their excipients
* Have pre proliferative and proliferative retinopathy, maculopathy requiring treatment or not clinically stable in the last 6 months, or participants with active changes in subjective eye symptoms as determined by the investigator if an eye exam has not been performed in the last 6 months
* Are receiving chronic (lasting longer than 14 consecutive days) systemic glucocorticoid therapy (excluding topical, intranasal, intraocular, and inhaled preparations) or have received such therapy within the 8 weeks immediately preceding screening
* Have fasting triglycerides greater than 400 mg/dL (4.5 mmol/L) at screening as determined by the central laboratory
* Have an irregular sleep/wake cycle (for example, participants who sleep during the day and work during the night) in the investigator's opinion
