Trial name or title |
A study with lifestyle intervention and study medication once weekly or lifestyle intervention and placebo in adolescents with obesity to explore differences between groups with regard to change in BMI |
Methods |
Type of trial: interventional; randomised controlled trial Allocation: randomised Intervention model: parallel assignment Masking: double blind Primary purpose: treatment |
Participants |
Condition: obesity in adolescents Enrolment: 44 Inclusion criteria:
signed informed consent prior to any trial‐specific procedures
males or females aged 10 to 18 years and 7 months
obesity (BMI SDS > 2.0 or age‐adapted BMI > 30 kg/m2), according to WHO
not sexually active or usage of adequate contraception. Female participants must also have negative pregnancy tests. Methods that can achieve a failure rate of less than 1% per year (Pearl index < 1), when used consistently and correctly, are considered as highly effective birth control methods. Such methods include:
combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal, transdermal
progestogen‐only hormonal contraception associated with inhibition of ovulation: oral, injectable, implantable
intrauterine device
intrauterine hormone‐releasing system
bilateral tubal occlusion
vasectomised partner
sexual abstinence (if refraining from heterosexual intercourse during the entire period of risk associated with the trial treatments. The reliability of sexual abstinence needs to be evaluated in relation to the preferred and usual lifestyle of the participant)
Exclusion criteria:
known syndromal obesity, such as Prader‐Willi syndrome, Laurence‐Moon syndrome or Bardet‐Biedl syndrome
pregnancy or lactation
indigestion‐causing diseases
severe gastrointestinal disease
total or partial gastric or small intestine resection
type 1 or type 2 diabetes mellitus
kidney disease (acute or chronic, according to physician (creatinine/urea/cystatin‐C for Schwartz calculation)
hypo‐/hyperthyroidism, unless under stable treatment
severe vitamin D insufficiency, unless under stable treatment
abnormal QT interval
clinically significant abnormal laboratory values, e.g. triglycerides > 400 mg/dL (Salzburg) or > 4.5 mmol/L (Uppsala), amylase > 300 U/L (Salzburg) or > 5.1 µkat/L (Uppsala), lipase > 180 U/L (Salzburg) or > 15 µkat/L (Uppsala) or calcitonin > 11.7 pg/mL (Salzburg) or > 3.4 pmol/L (Uppsala) for females and > 17 pg/mL (Salzburg) or > 5.0 pmol/L (Uppsala) for males
severe depression, severe anxiety or other psychiatric disorder referred to or undergoing special treatment, as judged by the investigator
severe sleep apnoea (defined clinically)
chronic diseases, as judged by the investigator
metformin treatment within 3 months prior to screening or concomitant medication influencing blood glucose (e.g. metformin and acarbose), influencing other parameters of metabolic syndrome (e.g. orlistat) or interfering with the investigational medicinal product
steroid treatment (oral or injected)
concomitant medication addressing attention disorders
antidepressants that can lead to weight gain, as judged by the investigator
hypersensitivity to exenatide or to any of the excipients
pacemaker or metal implant that may interfere with MRI
claustrophobia
current or prior (within 3 months) participation in another clinical trial involving an investigational medicinal product
a personal or family history of medullary thyroid carcinoma
a personal or family history of multiple endocrine neoplasia syndrome type 2

Interventions |
Intervention: exenatide + lifestyle intervention Comparator: placebo + lifestyle intervention |
Outcomes |
Primary outcome:
Secondary outcomes:
adverse events, vital signs (blood pressure and pulse), electrocardiogram, tympanic body temperature, glucose, clinical chemistry, haematology and urinalysis
endpoints of insulin secretion and sensitivity derived from oral glucose tolerance test
glucagon levels at specified time points
triglycerides, high‐density lipoprotein, low‐density lipoprotein, total cholesterol, free fatty acids, apolipoproteins, uric acid and blood pressure
highly sensitive C‐reactive protein
bioimpedance assessments to calculate total and regional body composition and MRI assessments of abdominal adipose tissue, organ fat characteristics and morphology (volume of visceral and abdominal subcutaneous adipose tissue and liver fat content)
waist, hip, upper thigh and neck circumference, waist‐to‐hip ratio, sagittal abdominal diameter and skinfold calipre assessments of body fat
standardised BMI
interdisciplinary adiposity evaluation kit (AD‐EVA), sleeping habits questionnaire, self‐efficacy and outcome expectations questionnaire, food frequency questionnaire, regular meals questionnaire, portion size questionnaire, walking test (6 min), physical activity questionnaire and physical activity assessed by accelerometry
U‐alpha1‐microglobulin (protein HC)/creatinine and estimated GFR according to Schwartz formula

Official title |
A parallel, double‐blinded, randomized, 6 months, two arms trial with lifestyle intervention and exenatide 2 mg once weekly or lifestyle intervention and placebo in adolescents with obesity to explore differences between groups with regard to change in BMI SDS (according to WHO) |
