Brief Summary:
This study will assess the safety, tolerability, pharmacokinetics (explores what the body does to the drug), and pharmacodynamics (explores what a drug does to the body) of multiple doses of JNJ-38431055 in volunteers with type 2 diabetes mellitus.

Condition or disease Intervention/treatment Phase
Diabetes Mellitus, Type 2 Drug: JNJ-38431055; Placebo Phase 1

Detailed Description:
This is a double-blind (neither physician or participant knows the name of the assigned study drug), placebo-controlled (substance containing no medication), study in male and female volunteers with type 2 diabetes mellitus. For each volunteer, the study consists of a screening phase (up to 45 days), a run-in phase during which volunteers discontinue their oral anti-hyperglycemic drugs (21 to 35 days), a treatment phase during which volunteers will continue to be off their anti-hyperglycemic drugs and receive daily study drug (JNJ-38431055 or placebo) for 14 days, and a follow-up phase (10 days). After the follow-up phase, volunteers will restart their oral anti-hyperglycemic drugs. The following safety evaluations will be taken throughout the study: Electrocardiogram (an ECG is a painless procedure that gives a picture of the electrical activity of the heart), blood pressure, heart rate, and blood samples for laboratory tests. The primary outcomes will be safety and tolerability of JNJ-38431055 and 24-hour weighted mean glucose concentrations after 14 days of dosing with JNJ-38431055. Study drug will be administered as daily doses for 14 days. The two treatments will be JNJ-38431055 and placebo.

Layout table for eligibility information
Ages Eligible for Study:   25 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Males or postmenopausal or surgically sterilized females, who have type 2 diabetes mellitus
  • Medically stable on the basis of physical examination, medical history, laboratory safety test results, vital signs and ECG performed at screening
  • Body Mass Index (BMI) between 22 and 39.9 kg/m2, inclusive
  • On a generally stable antihyperglycemic agent regimen (i.e. with no change in medication, or only 1 dose step change in dose) for at least 2 months prior to Screening visit, including volunteers who are: (a) Not currently on antihyperglycemic therapy and have an HbA1c >=7.0 % and <=10%, or (b) On a single oral antihyperglycemic agent [metformin, a sunfonylurea, a meglitinide (e.g., repaglininide or nateglinide), a DPP-IV inhibitor (sitagliptin or vildagliptin), or an alpha-glucosidase inhibitor (e.g., acarbose)] and have an HbA1c >=6.5% and <=9.5%, or (c) On low-dose dual oral agent therapy (i.e., <50% maximum labeled doses of both agents) and have an HbA1c >=6.5% and <=9.5%
  • On Day -2 (two days prior to study drug administration), FPG concentrations between 120 mg/dL and 260 mg/dL, inclusive

Exclusion Criteria:

  • Taking non-oral antihyperglycemic agent (e.g., insulin, exenatide or other GLP-1 analogues), or taking a thiazolidinedione (i.e., a PPARg agonist) within 3 months of the Screening visit
  • History of a recent severe hypoglycemic episode, recurrent hypoglycemic episodes (i.e., within the past year), or a history of hypoglycemic unawareness
  • History of clinically significant diabetic complications, including retinopathy, nephropathy, neuropathy or gastroparesis
  • Positive test for alcohol and/or drugs of abuse
  • Psychological and/or emotional problems, which would render the informed consent invalid, or limit the ability of the volunteer to comply with the study requirements
  • Any condition that, in the opinion of the investigator, would compromise the well being of the volunteer or the study or prevent the volunteer from meeting or performing study requirements
