Study summary

Men diagnosed with metabolic syndrome (MetS) including obesity, hypertension, dyslipidemia and infertility will be assessed for cardiovascular and diabetes risk. The eligible patient will be randomised to one-year life-style intervention program including nutritional, behavioural and exercise counselling or standard care by the general physician. The aim of the program is to reduce cardiovascular and diabetes risks and hypogonadism as well.

    Behavioral: Life style change and weight reduction

  • No intervention
    Standard treatment group

    Patients will be taken care of by general physician without lifestyle program.

Interventions

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2021 (actual). Primary completion is estimated for Dec 2023, 35 months after the start.

Of 594 non-industry interventional studies with no phase under Metabolic Syndrome, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 40. This study's planned 35 months is above that.

Counting every sponsor, half of 640 studies reached it within 20 months; a quarter within 9 and three quarters within 40.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 11, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
