Official Title: The Effect of Tesofensine on Energy Balance in Humans. A Randomised, Double-Blind, Placebo-Controlled, Parallel- Group, Single Centre Study.
Study Start Date : March 2007
Actual Primary Completion Date : December 2007
Actual Study Completion Date : December 2007

Primary Outcome Measures :
  1. Effect on 24-h EE (energy expenditure) after 14 days dosing, adjusted for FFM(Fat-Free Mass) and FM (Fat Mass) changes

Secondary Outcome Measures :
  1. 24-h fat oxidation, spontaneous physical activity, fecal excretion of energy and fat (respiratory chamber),Changes in body weight and composition
  2. Physical Measure(Waist circumference, waist-hip ratio, change in BMI, Sagittal diameter and DEXA, Spontaneous energy intake at lunch test
  3. Metabolic measures (Total triglycerides, Cholesterol-total, LDL-C, HDL-C, LDH, Blood glucose fasting, HbA1c, C-reactive protein, Insulin, Adiponectin, FFA, CCK, Ghrelin, and Leptin)
  4. Data from questionnaires( Satiety & Appetite, POMS Brief)
  5. Safety & Tolerability

Ages Eligible for Study:   18 Years to 50 Years   (Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Overweight to obese subjects with BMI 28 - 35 kg/m² otherwise healthy
  • Males 18 to 50 years of age, extremes included
  • Subjects should be able to comply with study procedures
  • Subjects giving written informed consent

Exclusion Criteria:

  • Use of any concomitant medication including high dose vitamins and regular OTC preparations
  • Subjects who have been smokers within the last year
  • Subjects with specific diseases interfering with their metabolism e.g. myxoedema, Cushing's syndrome, Type 1 diabetes mellitus, significant neurological or psychiatric illness such as epilepsy, schizophrenia, depression, eating disorders such as bulimia.
  • Subjects with Type 2 diabetes mellitus are ineligible unless anti-diabetic medication was not deemed necessary by the investigator and fasting (venous or arterialized capillary full blood from finger or ear) blood glucose > 6.1 mmol/l at screening. Re-test is allowed if first measure is above inclusion value. The corresponding exclusion criteria for plasma glucose is 7.0 mmol/l
  • Known hypercholesterolaemia (> 7 mmol/l).
  • Known hypertriglyceridaemia (> 3 mmol/l).
  • Malabsorptive intestinal disorders that can be assumed to affect the absorption of tesofensine
  • Mental or psychiatric disorder based on medical history only
  • Subjects with systemic infections or inflammatory diseases
  • Subjects currently (within the past 2 months) known to abuse or to be dependent on any drug, including alcohol (weekly consumption > 21 units of alcohol )
  • Hepatic or renal dysfunction (ASAT and/or ALAT > 2 x ULN and creatinine clearance < 30 mL/min estimated by central laboratory using Cockcroft and Gault formula, respectively)
  • Special diets (e.g., vegetarian, Atkins)
  • Subject should not be athletics or planning major changes in physical activity during the study to an extent that may interfere with the study outcome, as judged by the investigator
  • Weight change of > 3 kg within 2 months prior to screening
  • Surgically treated obesity
  • History or presence of significant cardiovascular disease such as heart failure, ischemic heart disease, stroke, transient ischemic attacks
  • Significant abnormalities on the ECG according to the investigators opinion. Additional exclusionary ECG values: QTcB > 450 milliseconds(ms), PR interval > 240 ms, QRS interval > 120 ms
  • Hypotension (i.e. supine systolic BP < 90 mm Hg) and/or symptomatic orthostatic hypotension (clinical symptoms of orthostatic hypotension associated with a decline ≥ 20 mm Hg in systolic BP at one minute after standing compared with the previous supine systolic BP obtained after 5 minutes of quiet rest) at screening visit
  • Hypertension (i.e. sitting diastolic BP ≥ 95 mm Hg and sitting systolic BP ≥ 155 mm Hg) as well as HR>90 bpm
  • Known HIV infection (no tests required)
  • Clinically significant or potentially disabling eye disorder, including uncontrolled glaucoma
  • Serologic evidence of active hepatitis B and/or C
  • History of cancer within the past 5 years, excluding treated basal cell carcinoma
  • Subjects previously treated with tesofensine
  • Subjects treated with an investigational drug within 30 days or 5 half-lives (whichever is longer) preceding the first dose of study drug
