  Purpose

Primary objective:

The primary objective of this study is to define the dose response of Glymera as measured as the change from baseline in hemoglobin A1c (HbA1c) following 20 weeks of once-weekly dosing.

Secondary objectives:

The secondary objectives are to:

  • Describe incidence, severity, and duration of reported gastrointestinal side effects of Glymera compared to active comparator;
  • Compare change from baseline in HbA1c following 20 weeks of dosing compared to placebo and active comparator;
  • Compare change from baseline in fasting plasma glucose (FPG) following 20 weeks of dosing compared to placebo and active comparator;
  • Describe the frequencies of adverse events in the treatment groups; and
  • Describe the above endpoints for the following subgroups of subjects according to baseline type 2 diabetes mellitus (T2DM) therapy: diet and exercise only, metformin only, sulfonylurea only, or metformin and sulfonylurea combination therapy.

Primary Outcome Measures:
  • Evaluation of dose response of Glymera as measured as the change from baseline in HbA1c after 20 weeks of dosing with Glymera compared to placebo and active comparator [ Time Frame: Baseline and 20 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Description of the incidence, severity, and duration of reported gastrointestinal side effects of Glymera compared to active comparator [ Time Frame: Up to 23 weeks ] [ Designated as safety issue: Yes ]
  • Compare change from baseline in weekly fasting plasma glucose (FPG) following 20 weeks of dosing compared to placebo and active comparator [ Time Frame: Baseline and 20 weeks ] [ Designated as safety issue: No ]
  • Describe the frequencies of adverse events in the treatment groups [ Time Frame: Up to 23 weeks ] [ Designated as safety issue: Yes ]
  • Proportion of subjects reaching HbA1c targets (<7.0%) after 20 weeks of dosing [ Time Frame: Baseline and 20 weeks ] [ Designated as safety issue: No ]

  Eligibility

Ages Eligible for Study:   18 Years to 75 Years

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male and female subjects 18 to 75 years of age, inclusive;
  • Body mass index ≤45 kg/m2;
  • Diagnosed with T2DM with HbA1c of ≥7.0% and ≤11.0% and treated with diet and exercise alone, or with stable doses of metformin alone, sulfonylurea alone or metformin and sulfonylurea.

Exclusion Criteria:

  • Currently taking or have taken within the last 6 months non-oral antihyperglycemic agents (eg, insulin, Byetta®, Bydureon®, or Victoza). Short-term use of insulin within this period will not be cause for exclusion if insulin was used during the treatment of an acute intercurrent illness;
  • Known allergy to or serious adverse effect caused by an approved or investigational glucagon-like peptide-1 (GLP-1) receptor analog/agonist;
  • Unstable cardiovascular disease;
  • History of weight loss surgery or other gastrointestinal surgical procedures that could possibly interfere with the mechanism of action of GLP-1 receptor agonists;
  • Based on contraindications/warnings identified with other GLP-1 receptor agonists, subjects will be excluded if they have: History, symptoms, or signs of pancreatitis or severe gastrointestinal disease (ie, gastroparesis) or Personal or family history of medullary thyroid tumors or history of Multiple Endocrine Neoplasia Syndrome Type 2;
  • Clinically significant renal and/or hepatic dysfunction;
  • Pregnant or lactating female subjects.
