Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients with type 2 diabetes mellitus who are taking metformin only. Treatment should be stable, where this is defined as no change in the treatment, including dose, over the past 2 months. Subjects treated with a sulfonylurea (SU) or a dipeptidyl peptidase-4 inhibitor (DPP-4i) in combination with metformin may be eligible if washed off the SU or DPP-4i to metformin only for a minimum of 4 weeks before dosing. Subjects being switched over from an SU and metformin or a DPP-4i and metformin to metformin only will still need to meet the fasting glucose requirements on Day -2 as defined in the protocol.
  • Body Mass Index (BMI) of 18.5 to 45.0 kg/m2; and a total body weight >50 kg (110 lbs).
  • Fasting C-peptide >0.8 ng/mL.
  • HbA1c >/=7% and >/=10%. If the patient requires to be washed off an SU or DPP-4i, the HbA1c limits will be >/=6.5% and </=9%.

Exclusion Criteria:

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease. Subjects who have chronic conditions other than T2DM (for example, hypercholesterolemia or hypertension) but are controlled by either diet or stable (for the last 2 months) doses of medications may be included as well.
  • Evidence or history of diabetic complications with significant end-organ damage.
  • Any condition possibly affecting drug absorption (eg, gastrectomy).
  • History of stroke, transient ischemic attack, or myocardial infarction within the past 6 months.
  • History of coronary artery bypass graft or stent implantation.
  • Clinically significant peripheral vascular disease.
  • Any history or clinical evidence of congestive heart failure, NYHA Classes II-IV.
  • Current history of angina/unstable angina.
  • ECG findings suggestive of asymptomatic myocardial ischemia or QTc >470 msec at screening.
  • One or more self-reported episodes of hypoglycemia within the last 3 months, or two or more self-reported episodes of hypoglycemia within the last 6 months.
  • Screening or Day -2 fasting (>/=8 hours) glucose, </=90 or >/=270 mg/dL, confirmed by a single repeat if deemed necessary.
  • A positive urine drug screen.
  • Use of tobacco or nicotine-containing products in excess of the equivalent of 10 cigarettes per day.
  • History of regular alcohol consumption exceeding 7 drinks/week for females or 14 drinks/week for males (1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of hard liquor) within 6 months of screening.
  • Certain concomitant medications are excluded, as defined in the protocol.
  • Screening supine blood pressure >/=160 mm Hg (systolic) or >/=100 mm Hg (diastolic).
  • Certain laboratory values (for example, triglyceride and liver function test results).
  • Pregnant or nursing females; females of childbearing potential.

Time Frame: 5 months
5 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
