Outcome Measures

Primary Outcomes (1)

  • Number of Participants With One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration

    An SAE is any AE from this study that results in one of the following outcomes: * Death * Initial or prolonged inpatient hospitalization * A life-threatening experience (that is, immediate risk of dying) * Persistent or significant disability/incapacity * Congenital anomaly/birth defect. * Important medical events that may not be immediately life-threatening or result in death or hospitalization, but may jeopardize the patient or may require. A summary of all SAE's, regardless of causality, is located in the Reported Adverse Events section.

    Baseline through Week 52

Secondary Outcomes (12)

  • Change From Baseline in Hemoglobin A1c (HbA1c)

    Baseline, Week 52

  • Percentage of Participants Who Achieve HbA1c <7%

    Week 52

  • Change From Baseline in Fasting Serum Glucose

    Baseline, Week 52

  • Mean Change From Baseline in Daily Average 7-Point Self-Monitored Blood Glucose (SMBG) Values

    Baseline, Week 52

  • Change From Baseline in Body Weight

    Baseline, Week 52

  • +7 more secondary outcomes

Eligibility Criteria

Age20 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participant must:
  • Have been diagnosed with type 2 diabetes mellitus based on the World Health Organization classification before the screening visit.
  • Have HbA1c ≥7.0% to \<11.0%, as determined by the central laboratory at screening.
  • Have been taking sulfonylureas, biguanides, thiazolidinedione, alpha-glucosidase inhibitor, glinides, or sodium-glucose cotransporter type 2 inhibitor monotherapy for at least 3 months before screening and have been on the following dose for at least 8 weeks before screening.
  • Have body mass index (BMI) of ≥23 kilograms per meter squared at screening.
  • Be of stable weight (±5%) during 3 months preceding screening; and agree to not initiate an intensive diet and/or exercise program during the study with the intent of reducing body weight other than the lifestyle and dietary measures for diabetes treatment.

You may not qualify if:

  • Participant must not:
  • Have type 1 diabetes mellitus.
  • Have had chronic or acute pancreatitis any time prior to study entry.
  • Have proliferative diabetic retinopathy or diabetic maculopathy or nonproliferative diabetic retinopathy requiring immediate or urgent treatment.
  • Have disorders associated with slowed emptying of the stomach, or have had any stomach surgeries for the purpose of weight loss.
  • Have acute or chronic hepatitis, signs and symptoms of any other liver disease, or blood alanine transaminase (ALT) enzyme level \>3.0 times the upper limit of normal (ULN) for the reference range, as determined by the central laboratory. Participants with nonalcoholic fatty liver disease (NAFLD) are eligible for participation in this trial only if there ALT level is ≤3.0 the ULN for the reference range.
  • Have had a heart attack, stroke, or hospitalization for congestive heart failure in the past 2 months.
  • Have a personal or family history of medullary thyroid carcinoma or personal history of multiple endocrine neoplasia syndrome type 2.
  • Have been taking weight loss drugs, including over-the-counter medications during the last 3 months.
