As applicable, all methods must be in effect prior to receiving the first dose of study medication.

- Presence of history of severe congestive heart failure (NYHA III and IV)
- Creatinin-Clearance of < 60 ml/min based on local laboratory results
- Concomitant medication with loop diuretics
- Patients who, as judged by the investigator, may be at risk for dehydration or volume depletion that may affect the patient's safety (including e.g. patients with a history of Diabetes insipidus)
- Pregnant women
- Administration of any other antidiabetic therapy, other than insulin (see inclusion criterion no.4 and 5) and metformin with a stable total daily dose ≥ 1500 mg or the maximum tolerated dose of metformin within 3 months prior to enrolment
- History of, or currently have, acute or chronic pancreatitis, or have triglyceride concentrations ≥ 700 mg/dL (≥ 7.98 mmol/L) at Visit 0 (Screening).
- History or presence of inflammatory bowel disease or other severe GI diseases, particularly those which may impact gastric emptying, such as gastroparesis or pyloric stenosis.
- History of gastric bypass surgery or gastric banding surgery, or either procedure is planned during the time period of the study. Current use of gastric balloons is also excluded.
- Significant hepatic disease, including, but not limited to, acute hepatitis, chronic active hepatitis, or severe hepatic insufficiency, including patients with alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) >3x upper limit of normal (ULN) and/or total bilirubin (TB) >2 mg/dL (>34.2 μmol/L) (patients with TB >2 mg/dL [>34.2 μmol/L] and documented Gilbert's syndrome will be allowed to participate).
- Known history of hepatotoxicity with any medication
- Known history of severe hepatobiliary disease.
- Positive serological test for hepatitis B or hepatitis C.
- Known or suspected human immunodeficiency virus (HIV) infection.
- History of organ transplantation.
- Presence or history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2 (MEN 2) OR a family history of medullary thyroid carcinoma or MEN 2.

- Patients with abnormal test results of hematocrit (hematocrit > 50% for men; hematocrit > 47% for women)
- Has donated blood or had a significant blood loss within 2 months of first dose of study medication or is planning to donate blood during the study.
- Has donated plasma within 7 days prior to first dose of study medication.
- Any exposure to Exenatide (including BYETTA®, BYDUREON, or exenatide suspension).
- Any exposure to Dapagliflozin or any SGLT-2 inhibitor.
Has been treated, is currently being treated, or is expected to require or undergo treatment with any of the following treatment excluded medications:
- Any DPP-4 inhibitor within 3 months prior to Visit 0 (Screening).
- Any GLP-1 analog within 1 year prior to Visit 0 (Screening).
- Systemic corticosteroids within 3 months prior to Visit 0 (Screening) by oral, intravenous, intra-articular, or intramuscular route; or potent, inhaled, or intrapulmonary (including ADVAIR) steroids known to have a high rate of systemic absorption.
