Evaluation of Long Term Safety of Tesofensine in Patients With Obesity

Purpose of the study is to evaluate the long term safety of tesofensine in obese patients


Eligibility Criteria:
Inclusion Criteria:

Patients who have completed their participation in TIPO-1

* Males and females 18 to 65,5 years of age, extremes included
* Patients continuously receiving diet therapy as well as instructions on exercise
* Females of childbearing potential must be non-pregnant and use safe contraceptive methods (the pill, IUD, injection of prolonged gestagen, sub dermal implantation, hormonal vaginal devices, transdermal patches or surgically sterilized)
* Patients should be able to comply with study procedures
* Patients giving written informed consent

Exclusion Criteria:

* Patients with a BMI\< 22
* Use of prescription medication as listed in Appendix 1
* Positive pregnancy test for women of childbearing potential
* Pregnant women, or women who are planning to become pregnant within the next 8 months
* Patients with specific diseases interfering with their metabolism e.g. untreated myxoedema, Cushing's syndrome, Type 1 diabetes mellitus, significant neurological or psychiatric illness such as epilepsy, schizophrenia, depression, eating disorders such as bulimia.
* Patients 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
* Patients known to abuse or to be dependent on any drug, including alcohol (weekly consumption \> 21 units of alcohol (men) or \>14 units of alcohol (women))
* 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)
* Known untreated hypercholesterolaemia (\> 7 mmol/l). Patients with well regulated cholesterol using drugs for hypercholesterolaemia are allowed inclusion
* Known untreated hypertriglyceridaemia (\> 3 mmol/l). Patients with well regulated triglyceride levels using drugs for hypertriglyceridaemia are allowed inclusion
* Drug treated thyroid diseases (well substituted hypothyroidism is allowed)
* Patients who suffer from hyperthyroid disease are not allowed in the study, even though they may be well treated by drugs
* Patients, who have recently diagnosed, not yet stable hypothyroid disease are not allowed in the study
* Patients who suffer from longstanding stable hypothyroid disease, well treated substitution are allowed to be included including hypothyroidism as a sequelae to definitive treatment of hyperthyroidism by surgery or radioactive iodine
* Malabsorptive intestinal disorders that can be assumed to affect the absorption of tesofensine
* Special diets (e.g., vegetarian, Atkins)
* Patients planning major changes in physical activity during the study to an extent that may interfere with the study outcome, as judged by the investigator
* Mental or psychiatric disorder based on medical history only
* Surgically treated obesity
* Patients with systemic infections or inflammatory diseases
* 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 \> 480 milliseconds (ms) in females and \>450 ms in males, 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
* Uncontrolled hypertension (i.e. sitting diastolic BP ≥ 95 mm Hg and sitting systolic BP ≥ 155 mm Hg) despite treatment for \> 4 weeks prior to the screening visit as well as HR\>90 bpm
* Known HIV infection (no tests required)
* History of cancer within the past 5 years, excluding treated basal cell carcinoma
* Clinically significant or potentially disabling eye disorder, including uncontrolled glaucoma
* Current treatment with medication with known ocular toxicity such as chloroquine and hydroxychloroquine is prohibited
* Patients treated with an investigational drug within 30 days or 5 half-lives (whichever is longer) preceding the first dose of study drug
