E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to demonstrate that once-weekly dulaglutide 1.5 mg is superior to placebo as measured by glycosylated hemoglobin A1c (HbA1c) at 24 weeks (change from baseline) in patients with type 2 diabetes mellitus on concomitant sulfonylurea therapy |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are as follows:
• To compare the effect of dulaglutide and placebo treatments at 24 wks:
o Change in body weight and body mass index from baseline
o Fasting blood glucose (central lab) and blood glucose values from the 7-point self-monitored plasma glucose
o Percentage of patients attaining HbA1c <7.0% and ≤6.5%
o Percentage of patients requiring an additional antihyperglycemic therapy
• To compare the safety of dulaglutide and placebo treatment groups at 24 weeks
o Cardiovascular (CV) system-related safety
o Pancreas-related safety
o Thyroid gland-related safety
o Glycemia-related safety: self-reported hypoglycemic events Dulaglutide anti-drug antibody titer and immune system-related adverse events |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Type 2 diabetes (based on the World Health Organization’s [WHO] diagnostic criteria)

b. HbA1c value of ≥7.5% and ≤9.5%
2. Accept continued treatment with sulfonylurea therapy, throughout the trial, as required per protocol

4. Stable weight (±5%) ≥3 months prior to screening
5. BMI ≤45 kg/m2 |
|
E.4 | Principal exclusion criteria |
1. Type 1 diabetes mellitus
2. Have been treated with ANY other antihyperglycemic medications (other than sulfonylurea) at the time of the first study visit or within 3 months of the first study visit
3. Have used insulin therapy (outside of pregnancy) any time in the past 2 years, except for short-term treatment of acute conditions, and up to a maximum of 4 weeks. Any insulin within 3 months prior to the first study visit is exclusionary.
4. Have been treated with drugs that promote weight loss within 3 months of the first study visit
5. Are receiving chronic (>14 days) systemic glucocorticoid therapy or have received such therapy within the 4 weeks immediately prior to the first study visit
6. Have had any of the following CV conditions within 2 months prior to the first study visit: acute myocardial infarction, New York Heart Association (NYHA) Class III or Class IV heart failure, or cerebrovascular accident (stroke)
7. Have a known clinically significant gastric emptying abnormality (eg, severe diabetic gastroparesis or gastric outlet obstruction) or have undergone gastric bypass (bariatric) surgery or restrictive bariatric surgery (eg, Lap-Band®)
8. Have acute or chronic hepatitis, signs and symptoms of any other liver disease, or alanine transaminase (ALT) level ≥2.5 times the upper limit of the reference range
9. Have a history of chronic pancreatitis or acute idiopathic pancreatitis, or were diagnosed with any type of acute pancreatitis
10. Have an estimated glomerular filtration rate [eGFR] <30 mL/min/1.73 m2
11. Have any self or family history of type 2A or type 2B multiple endocrine neoplasia (MEN 2A or 2B) in the absence of known C-cell hyperplasia (this exclusion includes those patients with a family history of MEN 2A or 2B, whose family history for the syndrome is RET negative; the only exception for this exclusion will be for patients whose family members with MEN 2A or 2B have a known RET mutation and the potential patient for the study is negative for that RET mutation)
12. Have any self or family history of medullary C-cell hyperplasia, focal hyperplasia, carcinoma (including sporadic, familial or part of MEN 2A or 2B syndrome) |
