A Study of LY2189265 in Japanese Participants With Type 2 Diabetes Mellitus

LS means were calculated using MMRM analysis with treatment, visit, treatment-by-visit, prestudy therapy (OAM yes/no), baseline BMI group (<25 or >=25 kg/m^2) as fixed effects, baseline HbA1c as a covariate, and participant as a random effect.

The percentage of participants achieving HbA1c level less than 7.0% and less than or equal to 6.5% at Week 26 and Week 52 was analyzed with a Cochran-Mantel-Haenszel test stratified by prestudy therapy (OAM yes/no) and baseline BMI group (<25 or >=25 kg/m^2).

LS means were calculated using MMRM analysis with treatment, visit, treatment-by-visit, prestudy therapy (OAM yes/no), baseline BMI group (<25 or >=25 kg/m^2) as fixed effects, baseline FBG as a covariate, and participant as a random effect.

Participants were to test and record SMBG concentrations in their study diaries before each meal (breakfast, lunch, and dinner), approximately 2 hours after the start of each meal, and at bedtime. LS means were calculated using analysis of covariance (ANCOVA) model with treatment, prestudy therapy (OAM yes/no), and baseline BMI group (<25 or >=25 kg/m^2) as fixed effects and baseline SMBG as a covariate.

LS means were calculated using MMRM analysis with treatment, visit, treatment-by-visit, prestudy therapy (OAM yes/no), baseline BMI group (<25 or >=25 kg/m^2) as fixed effects, baseline body weight as a covariate, and participant as a random effect.

HOMA 2 quantifies insulin resistance and beta-cell function. HOMA2-S is a computer model that uses fasting plasma insulin and glucose concentrations to estimate insulin sensitivity (%S) as a percentage of a normal reference population (normal young adults). The normal reference population was set at 100%. Change in insulin sensitivity was assessed based on change from baseline of HOMA2-%S using fasting insulin (FI) and fasting C-peptide (FCP). LS means were calculated using ANCOVA model with treatment, prestudy therapy (OAM yes/no), and baseline BMI group (<25 or >=25 kg/m^2) as fixed effects and baseline HOMA2-%S as a covariate.

HOMA 2 quantifies insulin resistance and beta-cell function. HOMA2-B is a computer model that uses fasting plasma insulin and glucose concentrations to estimate steady state beta-cell function (%B) as a percentage of a normal reference population (normal young adults). The normal reference population was set at 100%. Change in beta-cell function was assessed based on change from baseline of HOMA2-%B using fasting insulin (FI) and fasting C-peptide (FCP). LS means were calculated using ANCOVA model with treatment, prestudy therapy (OAM yes/no), and baseline BMI group (<25 or >=25 kg/m^2) as fixed effects and baseline HOMA2-%B as a covariate.

The percentage of participants with hypoglycemic episodes was calculated by dividing the number of participants with at least one hypoglycemic episode over the 26-week or 52-week treatment period by the total number of participants analyzed, multiplied by 100%. All classifications of hypoglycemia (documented symptomatic, asymptomatic, severe, nocturnal, non-nocturnal, probable symptomatic, relative, and unspecified) were included, except for episodes of relative hypoglycemia that were not severe. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

The 30-day total hypoglycemia rate over 26 weeks and 52 weeks of treatment is summarized. All classifications of hypoglycemia (documented symptomatic, asymptomatic, severe, nocturnal, non-nocturnal, probable symptomatic, relative, and unspecified) were included, except for episodes of relative hypoglycemia that were not severe. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

Deaths and nonfatal cardiovascular adverse events were adjudicated by a committee of physicians with cardiology expertise external to the Sponsor. The nonfatal cardiovascular events subjected to adjudication included myocardial infarction, hospitalization for unstable angina, hospitalization for heart failure, coronary interventions (such as coronary artery bypass graft or percutaneous coronary intervention), and cerebrovascular events including cerebrovascular accident (stroke) and transient ischemic attack. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

Sitting pulse rate was measured. LS means were calculated using ANCOVA model with treatment, prestudy therapy (OAM yes/no), and baseline BMI group (<25 or >=25 kg/m^2) as fixed effects and baseline pulse rate as a covariate.

Sitting systolic blood pressure (SBP) and sitting diastolic blood pressure (DBP) were measured. LS means were calculated using ANCOVA model with treatment, prestudy therapy (OAM yes/no), and baseline BMI group (<25 or >=25 kg/m^2) as fixed effects and baseline blood pressure as a covariate.

Events of pancreatitis (including suspected pancreatitis and severe or serious abdominal pain) were adjudicated by a committee of expert physicians external to the Sponsor. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

Pancreatic enzyme (lipase and total amylase) concentrations were measured.

A participant was considered to have treatment-emergent LY2189265 ADAs if the participant had at least 1 titer that was treatment-emergent relative to baseline, defined as a 4-fold or greater increase in titer from the baseline measurement.

Additional intervention was defined as any additional therapeutic intervention in participants who developed persistent, severe hyperglycemia despite full compliance with the assigned therapeutic regimen, or initiation of an alternative antihyperglycemic medication following study drug discontinuation. The number of participants requiring additional intervention due to hyperglycemia is summarized cumulatively at 26 and 52 weeks.

Fridericia Corrected QT (QTcF) Interval and PR Interval are summarized. The QT interval is a measure of the time between the start of the Q wave and the end of the T wave and was calculated from electrocardiogram (ECG) data using Fridericia's formula: QTcF = QT/RR^0.33. Corrected QT (QTc) is the QT interval corrected for heart rate and RR, which is the interval between two R waves. PR is the interval between the P wave and the QRS complex. LS means were calculated using ANCOVA model with treatment as a fixed effect and the baseline ECG parameter as the covariate.
