Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Prestudy treatment for patients who enter this study will be once daily insulin glargine along with mealtime insulins. Patients will continue to use their mealtime insulins throughout the study. The study will consist of 16 weeks of treatment and 4 weeks of follow-up. The 16 weeks of treatment will consist of two 8-week periods (Periods 1 and 2) during which patients will receive insulin glargine for 8 weeks and LY2605541 for 8 weeks in a random sequence. During the 4-week follow-up period, patients will return to insulin glargine or another basal insulin recommended by the investigator.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Daily Average Blood Glucose (Avg. BG) at Week 8 Endpoint as Measured by the 8-Point Self-Monitored Blood Glucose (SMBG) Profiles
Time Frame: Week 8 of each treatment period
It is the Avg. of the 8-point SMBG profiles, BG of morning fasting, midday & evening pre-meal, 2-hour postprandial after each of the 3 main meals, bedtime, 0300 hours. Least squares (LS) mean of daily Avg. BG is from mixed-model repeated measures (MMRM), which includes fixed effects of treatment (LY2605541, Glargine); Treatment Sequence; treatment period; dose conversion (pre-interim analysis [IA], post-IA); stratification variables (country, baseline daily basal insulin dose group, and baseline Hemoglobin [HbA1c] group); visit; visit and treatment interaction; a random effect for participant.
Week 8 of each treatment period

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Daily Average Blood Glucose (Avg. BG) at Week 8 Endpoint as Measured by the 8-Point Self-Monitored Blood Glucose (SMBG) Profiles
Time Frame: Baseline, Week 8 of each treatment period
It is the Avg. of the 8-point SMBG profiles, BG of morning fasting, midday & evening pre-meal, 2-hour postprandial after each of the 3 main meals, bedtime, 0300 hours. LS mean of daily Avg. BG is from MMRM, which includes fixed effects of treatment (LY2605541, Glargine); Treatment Sequence; treatment period; dose conversion (pre-IA, post-IA); stratification variables (country, baseline daily basal insulin dose group, and baseline HbA1c group); visit; visit and treatment interaction; a random effect for participant.
Baseline, Week 8 of each treatment period
Change From Baseline in Hemoglobin (HbA1c) at Week 8 Endpoint of Period I
Time Frame: Baseline, Week 8 (Period I)
HbA1c is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. LS mean of the change from baseline to 8-week at Period I is from MMRM approach, which includes fixed effects of treatment (LY2605541, Glargine); dose conversion (pre-IA, post-IA); stratification variables (country, baseline daily basal insulin dose group); baseline HbA1c; visit; interaction between visit and treatment; and a random effect for participant.
Baseline, Week 8 (Period I)
Percentage of Participants With HbA1c <7.0% and HbA1c ≤6.5% at Week 8 Endpoint of Period I
Time Frame: Week 8 (Period I)
HbA1c is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time.
Week 8 (Period I)
Percentage of Participants With HbA1c <7.0% and HbA1c ≤6.5% at Week 8 Endpoint Who Did Not Experience a Hypoglycemic Episode During Treatment (Period I)
Time Frame: Week 8 (Period I)
HbA1c is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. Hypoglycemia episode is defined as any time a participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia or has a BG level of ≤3.9 millimole/Liter (mmol/L) (≤70 milligram/deciliter [mg/dL]) even if it was not associated with signs, symptoms, or treatment (consistent with current guidelines [ADA 2005]).
Week 8 (Period I)
8-Point Self-Monitored Blood Glucose (SMBG) Measures at Week 8 Endpoint
Time Frame: Week 8 of each treatment period
8-point SMBG profiles are measured at morning fasting BG (FBG), midday pre-meal BG, evening pre-meal BG, 2-hour postprandial BG after each of the 3 main meals, bedtime BG, 0300 hours BG. LS mean is obtained from MMRM approach, which includes fixed effects of treatment (LY2605541, Glargine); treatment sequence; treatment period; dose conversion (pre-IA, post-IA); stratification variables (country, baseline daily basal insulin dose group, and baseline HbA1c group); visit; interaction between visit and treatment; and a random effect for participant.
Week 8 of each treatment period
Daily Basal Insulin Dose at Week 2 and Week 8 Endpoint
Time Frame: Week 2 and Week 8 of each treatment period
LS mean is obtained from MMRM approach, which includes fixed effects of treatment (LY2605541, Glargine); treatment sequence; treatment period; dose conversion (pre-IA, post-IA); stratification variables (country, baseline daily basal insulin dose group, and baseline HbA1c group); visit; interaction between visit and treatment; and a random effect for participant.
Week 2 and Week 8 of each treatment period
Pharmacokinetics - Drug (LY2605541) Concentration at Steady State (Css) at Week 8 Endpoint
Time Frame: Week 8 of each treatment period
The drug (LY2605541) concentration at steady state (Css) is calculated from the clearance (Liter/hour) and the final dose of the participants. Clearance was estimated using population-based approaches.
Week 8 of each treatment period
Percentage of Participants With Antibody Status Change From Baseline to Week 8, Week 16 and Week 20
Time Frame: Week 8, Week 16 and Week 20
Negative is defined as either 'negative' from lab or percent binding <1.16%. Positive is defined as the percent binding is ≥1.16%. The antibody status change is from negative to positive or positive to negative.
Week 8, Week 16 and Week 20
Percentage of Participants With Hypoglycemia Baseline Through Week 8
Time Frame: Baseline through Week 8 of each treatment period
Hypoglycemia episode is defined as any time a participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia or has a BG level of ≤3.9 millimole per Liter (mmol/L) (≤70 milligram per deciliter [mg/dL]) even if it was not associated with signs, symptoms, or treatment (consistent with current guidelines [ADA 2005].
Baseline through Week 8 of each treatment period
Rate of Hypoglycemia Per 30 Days Baseline Through Week 8
Time Frame: Baseline through Week 8 of each treatment period
Hypoglycemia episode is defined as any time a participant feels that he/she is experiencing a sign or symptom that is associated with hypoglycemia or has a BG level of ≤3.9 mmol/L (≤70 mg/dL) even if it was not associated with signs, symptoms, or treatment (consistent with current guidelines [ADA 2005].

Baseline through Week 8 of each treatment period
Glycemic Variability in Fasting Blood Glucose (FBG) at Week 8 Endpoint

Within-patient glycemic variability was assessed as the standard deviation of fasting blood glucose each day between Week 6 and Week 8. LS mean is obtained from MMRM approach, which includes fixed effects of treatment (LY2605541, Glargine); treatment sequence; treatment period; dose conversion (pre-IA, post-IA); stratification variables (country, baseline daily basal insulin dose group, and baseline HbA1c group); visit; interaction between visit and treatment; and a random effect for participant.
