Study summary

The aim of the study is to evaluate the effect of a 12-week liraglutide treatment as an addition to dietary intervention in comparison to dietary intervention alone on body weight, body composition, ectopic lipid accumulation and insulin sensitivity in subjects with overweight or obesity.

Read the detailed description

Overweight and obesity are associated with an increased risk of metabolic complications and cardiovascular disease, and even moderate weight loss may lead to significant improvement in metabolic profile. The influence of GLP-1 receptor agonists (GLP-1RAs), such as liraglutide, on body weight and body composition, ectopic fat accumulation and insulin sensitivity is not fully elucidated. It is also unclear whether potential beneficial metabolic effects of GLP-1RAs are only weight-loss dependent or are there other mechanisms independent of weight loss. Therefore, the study aims to assess the impact of a 12-week liraglutide treatment on body weight, body composition, ectopic lipid accumulation and insulin sensitivity in subjects with overweight or obesity without diabetes.

The study subjects will be randomly assigned to one of two groups: receiving liraglutide in the maximum dose of 1.8 mg s.c. daily + low calorie diet or receiving low-calorie diet only. The intervention time will be 12 weeks, with control visits and dietary counselling every 4 weeks. Post-intervention visits to assess whether the achieved results are maintained will be performed at 1, 3, and 6 months after completing the intervention.

Exclusion Criteria:

  • diabetes diagnosed previously or during screening
  • chronic inflammatory diseases

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

  • Active comparator
    Low-calorie diet

    Low-calorie diet Duration: 12 weeks

    Other: Low-calorie diet with dietician's monitoring

Interventions

  • Liraglutide dosing: * Week 1: 0.6 mg once daily * Week 2: 1.2 mg once daily * Weeks 3-12: 1.8 mg once daily

  • OtherLow-calorie diet with dietician's monitoring

    Low glycemic index diet with a deficit of 500 kcal/day in relation to the participant's individual total daily energy expenditure. The nutrient goals for the diet are established at 45% energy from carbohydrates, 30% from fat, and 25% from protein. All participants will receive detailed guidelines and personalized menus for each day of the intervention before the start and every 4 weeks during the intervention.
