A Study of the Safety, Pharmacokinetics, and Pharmacodynamics of CNTO 3649 in Healthy Adults and Patients With Type 2 Diabetes Mellitus
A Study of the Safety, Pharmacokinetics, and Pharmacodynamics of CNTO 3649 in Healthy Adults and Patients With Type 2 Diabetes Mellitus
The purpose of this study is to evaluate the safety, pharmacokinetics, and pharmacodynamics
 of CNTO 3649 following a single dose in healthy adults and following multiple doses in
 patients with Type 2 Diabetes Mellitus.
This is a randomized (study medication assigned by chance), placebo controlled, double-blind
 (neither physician nor patient knows the name of the assigned study medication),
 ascending-dose study to assess the safety, tolerability, immune response, pharmacokinetics
 (what the body does to the drug), and pharmacodynamics (what the drug does to the body) of
 CNTO 3649. The study population will consist of approximately 80 healthy participants (Part
 1) and approximately 36 type 2 diabetic patients (Part 2). All participants will be
 randomized to CNTO 3649 or placebo in the ratio of 3:1. Out of 80 healthy participants, 48
 participants will receive single doses of CNTO 3649 (6 dose levels) or placebo as an
 intravenous infusion (directly into a vein) and 32 participants will receive single doses of
 CNTO 3649 (4 dose levels) or placebo as a subcutaneous (under the skin) injection. All 36
 diabetic patients will receive multiple doses of CNTO 3649 (3 dose levels) or placebo as
 subcutaneous injections. There will be a screening period of 30 days and 45 days for healthy
 participants and diabetes patients, respectively. Healthy participants will be in the study
 for 9 weeks. Diabetic patients will be in the study for 12 weeks.
Inclusion Criteria:

 -  Part 1 (healthy participants): Demonstrate an understanding of the study and sign an
 informed consent form

 -  Healthy male or female subjects with no clinically relevant abnormalities as
 determined by medical history, physical examination, blood chemistry assessments,
 hematologic assessments including complete blood count, coagulation tests, urinalysis,
 measurement of vital signs, and ECG

 -  Age 18 to 55

 -  Have a body mass index (BMI) of 18.5 to 30 kg/m2 and weight of 50 to 100 kg

 -  Part 2 (patients with type 2 diabetes): Type 2 Diabetic male or female subjects
 diagnosed at least 12 months prior to screening and are stably managed for >= 3 months

 -  HbA1c levels within the range of 6% to 10% if being treated with diet and exercise
 alone, and 6% to 9% if on therapy

 -  BMI 18.5 to 37 kg/m2. Age 18 to 65 years.

 Exclusion Criteria:

 -  Part 1 (healthy participants): Currently have or have a history of any clinically
 significant medical illness or medical disorders the investigator considers should
 exclude the subject

 -  Part 2 (patients with type 2 diabetes): Any clinically significant medical illness or
 medical disorders (with the exception of diagnosis of T2DM, well-controlled
 hypertension, or well-controlled dyslipidemia) the investigator considers should
 exclude the subject. History of more than 3 days of insulin use in the last 3 months,
 or any thiazolidinedione medications, any alpha glucosidase inhibitors, or exenatide
 within 3 months of the screening visit. History of clinically significant acute or
 chronic diabetic complications. History of severe hypoglycemic reaction in the 6
 months prior to the screening visit.
