Identifying Individuals At Risk of Glucocorticoid-Induced Impairment of Bone Disease

Phase 2RecruitingNCT06421597

Odense University Hospital36 enrolled

Overview

Previous studies have shown that there is a large inter-individual variability in the degree of bone loss during glucocorticoid treatment, and while some patients experience extensive bone loss other patients\' bone mass remains stable. The aim of the study is to find a biomarker that can be used to identify individuals at risk of glucocorticoid-induced bone loss. The study will include 36 healthy volunteers, that will be randomized to receive either glucocorticoid treatment or placebo. During the study blood samples, bone marrow samples, bone tissue samples, and adipose tissue samples are taken and an oral glucose tolerance test is performed.
