NCT06556277

Brief Summary

The investigator aim to understand whether food-induced glucocorticoids influence fat mass in overweight and obese people. In a randomized, cross-over study, 23 overweight and obese volunteers will receive a block and replace therapy that mimics physiological glucocorticoid (GC) rhythm (metyrapone plus hydrocortisone) or placebo. Participants will undergo two identical overfeeding periods with each treatment. With the block and replace therapy food-induced GC peak will be suppressed. Metabolic and immunological parameters will be compared to reveal the effects of GCs during excessive overfeeding, particularly to understand changes in body fat.

Study Arms (2)

Metyrapone And Hydrocortisone

EXPERIMENTAL

During one of the study periods, subjects receive hydrocortisone 19.9 mg/d day 1 to day 6 and 12 mg/d on day 7 subcutaneously via a pump in a pulsed fashion (eight times/day) and metyrapone per os (starting with a dose of 750 mg/d, then the dose will be increased on day 3, where 2500mg/d is achieved and reduced on day 7 to 750mg).

Drug: Metyrapone And Hydrocortisone

Placebo

PLACEBO COMPARATOR

During the other study period, subjects receive placebo (0,9% NaCl solution) the same dose of placebo instead of hydrocortisone subcutaneously via a pump in a pulsed fashion and the same dose of placebo tablets p.o instead of metyrapone.

Drug: Placebo

Interventions

Drug: Metyrapone 250 mg Oral Tablets During one phase of the study: Metyrapone (pills of 250mg) on full stomach: Day 1 0-1-2, day 2 1-2-2, day 3 3-3-4 day 4 3-3-4 day 5 3-3-4 day 6 3-3-4 day 7 3-0-0 Drug: Hydrocortisone 19,9mg/12mg s.c., pulsatile with a flow rate of 10μl/s Hydrocortisone will be delivered subcutaneously via a pump in a pulsed fashion with a flow rate of 10μl/s from day 1 to day 6 in a total daily dose of 19.9mg and 12mg on day 7

Metyrapone And Hydrocortisone

Drug: Placebo 250 mg Tablets During another phase of the study: identical looking placebo pills starting Day 1 During one phase of the study: Metyrapone (pills of 250mg) on full stomach: Day 1 0-1-2, day 2 1-2-2, day 3 3-3-4 day 4 3-3-4 day 5 3-3-4 day 6 3-3-4 day 7 3-0-0 Drug: Placebo (0,9% NaCl solution) Placebo (0,9% NaCl solution) 19.9 mg/d subcutaneously via a pump in a pulsed fashion with a flow rate of 10μl/s from day 1 to day 6 and 12mg on day 7

Placebo

Eligibility Criteria

Age18 Years - 50 Years
Sexmale(Gender-based eligibility)
Gender Eligibility DetailsSince hormone fluctuations associated with the menstrual cycle may alter cortisol levels, women will not be included in the study. Although diversity will be reduced and the statements of the study cannot be applied to the female sex, these strict inclusion criteria allow an optimal homogeneity and increase statistical power.
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Males aged 18 to 50 years
  • BMI≥ 25 kg/m² with a stable weight within past three months before study initiation

  • Any severe acute or chronic disease, including diabetes mellitus type 2
  • Intake of GLP-1 agonists or hormone therapy
  • Hypercortisolism
  • Casual smoking (more than 6 cigarettes per day)
  • Frequent, heavy alcohol consumption (more than 30g/day)
  • Frequent, heavy caffeine consumption (more than 4 caffeinated drinks/day)
  • Regular physical exercise (more than 4hrs per week)
  • Shift work
  • Participation in an investigational drug trial within the past two months
