NCT ID NCT06533007

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at how a gene called PDE3B affects fat tissue and the body's ability to handle sugar and fats. Researchers will compare two groups of people: those with a natural gene variant and those without. The goal is to understand if this gene could be a target for preventing or treating type 2 diabetes and heart disease.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Participants with heterozygous for PDE3B LoF variants will be recruited from existing research cohorts (i.e., the Oxford Biobank, the NIHR BioResource at the University of Cambridge and the Fenland study populations (1:700 frequency of the LoF variant). Subsequently, individuals without the variant of interest will be recruited from the same cohorts to establish a WT group of individuals matched for age, sex, race/ethnicity, and body fat percent.

Ages

21 to 75 years

Sex

Anyone
