KRN23 effects on phosphate and vitamin D dysregulation in children <5 years old with X-Linked Hypophosphatemia (XLH)

Imel Erik , Carpenter Thomas , Gottesman Gary S , Martin Javier San , Mao Meng , Skrinar Alison , Whyte Michael P

Objectives: XLH features renal phosphate (Pi) wasting, hypophosphatemia, rickets, and skeletal deformities from elevated circulating levels of fibroblast growth factor 23 (FGF23). KRN23, an investigational fully human monoclonal antibody, binds FGF23 and inhibits its action. Our Phase 2 study of KRN23 in XLH children (ages 5–12 years) is demonstrating improvements in serum Pi and rickets. Here we present our Phase 2 trial evaluating the efficacy and safety of KRN23 in you...

Mass spectrometric immunoassay for intact parathyroid hormone: correlation with immunoassay and application to clinical samples

Couchman L , Taylor D , Krystans B , Lopez M , Prakash A , Sarracino D , Garces A , Vogelsang M , Peterman S , Vadali G , Robinson S , Moniz C

Introduction: Parathyroid hormone (PTH) measurement is of use in i) differential diagnosis of hypercalcaemia and ii) patients with renal impairment at risk of bone disease. PTH immunoassays are complicated by cross-reactivity with truncated (inactive) variant forms, which accumulate in patients with renal impairment. PTH assay variability is a critical governance issue in renal medicine, suggesting an MS-based reference method is required.Aim: To develop...

Effects of romosozumab administration on trabecular and cortical bone assessed with quantitative computed tomography and finite element analysis

Graeff C , Campbell G , Pena J , Padhi D , Grossman A , Chang S , Libanati C , Gluer C-C

Romosozumab is an investigational bone-forming agent that inhibits sclerostin. Recent data demonstrated that it stimulated bone formation, decreased bone resorption, and led to rapid and substantial increases in areal bone mineral density (BMD; McClung, J Bone Miner Res 27 (S1) S8–S9, 2012). In a Phase 1b, randomized, double-blind, placebo-controlled, multiple dose study, we studied the effects of romosozumab administered for 3 months and follow-...

Synergistic anti-tumour effects on human breast cancer cells by mevalonate pathway inhibitors atorvastatin and zoledronic acid

Gobel Andy , Thiele Stefanie , Rauner Martina , Lorenz C Hofbauer , Tilman D Rachner

Introduction: Bone metastases represent a frequent complication of breast cancer and are characterized by increased tumour-driven activation of osteoclasts and subsequent bone loss. Aminobisphosphonates inhibit osteoclast function and are established therapies of skeletal metastases. Similar to statins, they block the mevalonate pathway and are thought to have direct anti-tumour effects. Here, we report on the anti-tumour potential of a sequential inhibition of the mevalonate ...
