UX023-CL303 is an ongoing, Phase 3, double-blind, multicenter study examining the efficacy and safety of burosumab, a fully human monoclonal antibody against FGF23, in adults with XLH. Eligible subjects had serum phosphorus levels <0.81 mmol/l and skeletal pain (BPI – Worst Pain ≥4). Subjects (N=134) were randomized 1:1 to receive burosumab 1 mg/kg or placebo subcutaneously every 4 weeks. After 24 weeks, subjects in the placebo group crossed-over to rec...

Receptor-activator of nuclear factor kB (RANK), its ligand RANKL and the soluble decoy receptor osteoprotegerin (OPG) are the key regulators of osteoclast differentiation and bone remodelling. Although there is a strong association between osteoporosis and skeletal muscle atrophy, the functional relevance of a particular biological pathway that regulates synchronously bone and skeletal muscle physiopathology remain elusive. We thus hypothesized that RANK/RANKL/OPG, which is a ...

Introduction: White adipose tissue (WAT) and brown adipose tissue (BAT) are key regulators of systemic metabolic function. Bone marrow adipose tissue (BMAT) accounts for 10% of total adipose mass in healthy humans and therefore can be considered a third major adipose subtype. However, it is unclear if BMAT contributes to systemic energy homeostasis.Objectives: Assess [18F]-Fluorodeoxyglucose (FDG) uptake into bone and the marrow cavity (MC) fo...

Standard therapy (ST) for chronic hypoparathyroidism (HPT) includes calcium and active vitamin D supplementation, which can be associated with an increased risk of renal complications. This study compared renal function change, assessed by estimated glomerular filtration rate (eGFR) over 5 years between HPT patients receiving rhPTH1-84 as an adjunct to ST and a historical control cohort without rhPTH1-84. rhPTH1-84-treated HPT patients were selected from two single-arm, long-t...

Background: Concerns about the effects of gender affirming hormonal treatment (HT) on bone mineral density (BMD) exists, particularly for transmen with decreasing estrogen levels. HT in transpersons affects BMD on short term, but long-term follow-up studies are lacking. Therefore this study aimed to investigate the change in BMD during the first 10 years of HT in adult transwomen and transmen, in order to determine whether it is necessary to assess BMD during HT.<p class="...
