Outcomes

Primary Outcomes

Change From Baseline in Glycosylated Hemoglobin (HbA1c) in Overweight and Obese Participants With Type 2 Diabetes Mellitus

Once weekly injections of LY2189265 (titrated and non-titrated doses) compared to placebo on blood glucose were evaluated. Least Squares (LS) means of change from baseline were calculated using analysis of covariance (ANCOVA) adjusting for treatment, combination of oral medications, and baseline glycosylated hemoglobin (HbA1c).

Time frame: Baseline, 16 weeks

Secondary Outcomes

Change From Baseline in Fasting Blood Glucose

Fasting blood glucose is a test to determine how much glucose (sugar) is in a blood sample after an overnight fast. Least Squares (LS) means of change were calculated using analysis of covariance (ANCOVA) adjusting for treatment, combination of oral medications, and baseline.

Time frame: Baseline, 16 weeks

Meal Test Glucose Excursion (Change in Blood Glucose to Test Meal)

Glucose excursion in response to a standardized solid mixed meal test was evaluated at baseline (randomization) and at Week 16, or at early termination. Each of the 2 standardized meal tests required participants to fast starting at 2200 hours the night prior to the test. A standardized breakfast meal was provided to the participant (approximately 550 kilocalorie \[Kcal\], 103 grams \[g\] carbohydrates, 22 g protein, and 8.5 g fat) and was to be consumed within 15 minutes. Serial venous blood samples were taken at the start of the meal (fasting \[0\]) and 30, 60, 90, 120, and 180 minutes after the start of the meal. Least Squares (LS) means of change in mean glucose area under the curve excursion following a test meal were calculated adjusting for treatment, combination of oral medications, and baseline.

Time frame: Baseline and 16 weeks

Change From Baseline in Daily Mean Blood Glucose Values From the 8-point Self Monitored Blood Glucose (SMBG) Profiles

Change from baseline in mean daily blood glucose values were measured using self-monitored blood glucose (SMBG) data collected at the following 8 time points: pre-morning meal; 2 hours post-morning meal; pre-midday meal; 2 hours post-midday meal; pre-evening meal; 2 hours post-evening meal; bedtime; and 2:00 am. The daily mean was calculated as the average of the 8 blood glucose values collected on a particular day. Least Squares (LS) means of change from baseline of the mean of the 8 time points (Daily Mean) were calculated using analysis of covariance (ANCOVA) adjusting for treatment, combination of oral medications, and baseline.

Time frame: 2 separate days in the week preceding the Baseline, Week 4, Week 8, and Week 16 visits.

Change From Baseline in Beta (β)-Cell Function and Insulin Sensitivity as Estimated by the Updated Homeostasis Model Assessment Method (HOMA2)

Homeostasis Model Assessment tool (HOMA2) of β-cell function is a technique for estimating beta-cell function (HOMA2-%B) and insulin sensitivity (HOMA2-%S) using basal serum glucose, and c-peptide concentrations. A fasting blood glucose, c-peptide, and serum insulin level were drawn for purposes of this determination just prior to the mixed meal test.

Time frame: Baseline, 16 weeks

Percentage of Participants Achieving a Glycosylated Hemoglobin (HbA1c) of <7% or ≤6.5%

Percentages of participants who achieved glycosylated hemoglobin (HbA1c) levels of \<7% or ≤6.5% were analyzed with a logistic regression model with baseline, combination of oral medications, and treatment as factors included in the model.

Time frame: Baseline and 4 and 8 and 16 weeks

Change From Baseline in Body Weight

LS means of change from baseline were calculated using analysis of covariance (ANCOVA) adjusting for treatment, combination of oral medications, and baseline.

Time frame: Baseline, 4, 8, and 16 weeks

Change From Baseline in Waist Circumference

Mean change from baseline in waist circumference (a measure of central obesity).

Time frame: Baseline, 16 weeks

Nausea and Dyspepsia Measured by Visual Analog Scale

Participants were asked to score nausea and dyspepsia (abdominal pain and bloating) on a scale of 0 (none) to 100 after the largest meal of the day.

Time frame: One week before and one week after each of the Baseline and Week 4 and Week 8 and Week 16 visits

Change From Baseline in Gastroparesis Cardinal Symptom Index (GCSI) Scores

Gastroparesis Cardinal Symptom Index (GCSI) is a participant-completed questionnaire designed to assess the severity of symptoms consistent with delayed gastric emptying (nausea/vomiting, abdominal bloating, and stomach fullness) at each study visit. GCSI scores ranged from 0=none, 1=very mild, 2=mild, 3=moderate, 4=severe, to 5=very severe.

Time frame: Baseline and 4 and 8 and 16 weeks

Number of Participants With a Hypoglycemic Event

A documented hypoglycemic episode is defined as an event which is associated with a measured blood glucose of ≤70 milligrams per deciliter (mg/dL) (3.9 millimoles per liter \[mmol/L\]), even if it was not associated with symptoms, signs, or treatment. A severe hypoglycemic episode is defined as an event with a measured blood glucose of \<50mg/dL. Participant reports of hypoglycemic events were collected at the beginning of each visit starting at Baseline. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

Time frame: Baseline through 4, 8, and 16 weeks

Rate of Hypoglycemia Per 30 Days

Hypoglycemic episodes are defined as an event which is associated with reported signs and/or symptoms of hypoglycemia (for example, sweating, shakiness, tachycardia, etc.) or a documented blood glucose (BG) concentration of ≤70 milligrams per deciliter (mg/dL) (3.9 millimoles per liter \[mmol/L\]), even if it was not associated with symptoms, signs, or treatment. The rate is the average number of days out of 30 that a participant reported hypoglycemia. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

Time frame: Baseline through 16 weeks

Change From Baseline in Lipids

Lipids include total cholesterol, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol, and triglycerides.

Time frame: Baseline, 16 weeks

Participants Perception of Medication Effectiveness Using the Perceptions About Medications - Diabetes, Short Version (PAM-D-S) Questionnaire

The Perceptions about Medications - Diabetes, Short Version (PAM-D-S) questionnaire consisted of: 2 items in which respondents were asked about their satisfaction with their diabetes medication over the past week using a 6-point scale ranging from 1 "completely dissatisfied" to 6 "completely satisfied"; 10 items in which respondents were asked about the effectiveness of their diabetes medications in the past week using a 4-point scale ranging from 1 "all of the time" to 4 "none of the time"; and 15 items asking respondents to indicate the frequency of physical side effects in the past week using a 4-point scale ranging from 1 "all of the time" to 4 "none of the time." These items were exploratory items taken from a Diabetes Medicines Survey and had not been validated as a scale. The percentage of participants that rated their general health as good or better are summarized.

Time frame: Baseline and 4 and 8 and 16 weeks

Validation of the Psychometric Properties of the Perceptions About Medications - Diabetes, Short Version (PAM-D-S) Questionnaire

This purpose of this outcome measure was to validate the PAM-D-S questionnaire for future use. Please refer to Outcome Measure #14 for a description of the PAM-D-S questionnaire and results collected. A preliminary analysis indicated modifications to the questionnaire were required and further study is necessary to complete the validation. Therefore, the PAM-D-S questionnaire was not validated as a part of Study H9X-MC-GBCJ.

Time frame: Baseline and 4 and 8 and 16 weeks
