Study Overview
Brief Summary
The purpose of this study is:
- To compare the blood sugar control of LY2605541 with insulin glargine after 78 weeks of treatment.
- To compare the rate of night-time low blood sugar episodes on LY2605541 with insulin glargine during 78 weeks of treatment.
- To compare the number of participants on LY2605541 reaching blood sugar targets without low blood sugar episodes at night to those taking insulin glargine after 78 weeks of treatment.
- To compare the rate of hypoglycemia episodes on LY2605541 with insulin glargine during 78 weeks of treatment.

- •Agree to continue to use a reliable method of birth control during the study, as determined by the investigator (and for 2 weeks following the last dose of study drug)
- •Capable of and willing and desirous to do the following: adhere to a multiple daily injection regimen, inject insulin with a prefilled pen and perform Self-Monitored Blood Glucose (SMBG) and record keeping as required by this protocol, as determined by the investigator. Caregiver may be responsible for all of the above.
Exclusion Criteria
- •Are using twice-daily insulin glargine having been inadequately controlled on once-daily dosed glargine prior to screening
- •Have excessive insulin resistance defined as having received a total daily dose of insulin greater than 1.5 units per kilogram (units/kg) at the time of randomization

- •If a participant has not been on a stable dose of lipid-lowering medication for greater than or equal to 90 days prior to screening, the site should wait to screen the participant. If the results of the screening laboratory tests require a change to the participant's current lipid-lowering medication or initiation of lipid-lowering medication, it is acceptable to change the lipid-lowering medication for the participant and to have the participant return greater than or equal to 90 days later to complete some of the screening procedures again

- •Total bilirubin greater than or equal to 2 times the upper limit of normal (ULN) as defined by the central laboratory,
- •Alanine aminotransferase (ALT)/(serum glutamic pyruvic transaminase (SGPT) greater than 2.5 times ULN as defined by the central laboratory, or
- •Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT) greater than 2.5 times ULN as defined by the central laboratory.

- •Allergy: Have known hypersensitivity or allergy to any of the study insulins or their excipients
- •Hematologic: Have had a blood transfusion or severe blood loss within 3 months prior to screening or have known hemoglobinopathy, hemolytic anemia, sickle cell anemia, or any other traits of hemoglobin abnormalities known to interfere with the HbA1c measurement
- •Glucocorticoid therapy: Receiving chronic (lasting longer than 14 consecutive days) systemic glucocorticoid therapy (excluding topical , intraocular, intranasal, and inhaled preparations) or have received such therapy within 8 weeks immediately before screening with the exception of replacement therapy for adrenal insufficiency
- •Diagnosed clinically significant diabetic autonomic neuropathy, in the opinion of the investigator

Primary Outcomes

Time Frame: 26 weeks
HbA1c is a test that measures a participant's average blood glucose level over a 2- to 3-month timeframe. Least Squares (LS) means were calculated using mixed model repeated measures (MMRM), adjusting for treatment, stratification factors (baseline low-density lipoprotein cholesterol \[LDL-C\] \[\<100 milligrams per deciliter (mg/dL) and ≥100 mg/dL\] and country), visit, treatment-by-visit interaction, and baseline HbA1c as the fixed effects and participant as the random effect.
