Filter by:The primary objective of this study is to establish the effect of KRN23 treatment on improvement in XLH-associated osteomalacia as determined by osteoid volume (osteoid volume/bone volume, OV/BV).
The primary efficacy objective of this study is to establish the effect of burosumab treatment compared with placebo on increasing serum phosphorus levels in adults with XLH.
The primary objectives of this study are to: - Assess the long-term safety of KRN23 subcutaneous (SC) administration in adult subjects with XLH - Assess the proportion of subjects achieving serum phosphorus levels in the normal range (2.5-4.5 mg/dL) with long-term administration of KRN23 - Assess long-term pharmacodynamics (PD) of KRN23 as measured by changes in the following: serum intact parathyroid hormone (iPTH); serum and urinary phosphorus; ratio of renal tubular maximum phosphate reabsorption rate to glomerular filtration rate (TmP/GFR) and tubular reabsorption of phosphate (TRP); serum 1,25-dihydroxy vitamin D (1,25[OH]2D); serum fibroblast growth factor 23 (FGF23); bone biomarkers: serum alkaline phosphatase (ALP), bone-specific ALP (BALP), carboxy terminal crosslinked telopeptide of type I collagen (CTx), and procollagen type 1 N-terminal propeptide (P1NP) - Assess long-term immunogenicity of KRN23 as measured by presence of anti-KRN23 antibody (ADA)
The objectives of the study are to: - Identify a dose and dosing regimen of burosumab, based on safety and pharmacodynamic (PD) effect, in pediatric XLH participants - Establish the safety profile of burosumab for the treatment of children with XLH including ectopic mineralization risk, cardiovascular effects, and immunogenicity profile - Characterize the pharmacokinetic (PK)/PD profile of the KRN23 doses tested in the monthly (Q4) and biweekly (Q2) dose regimens in pediatric XLH patients - Determine the PD effects of burosumab treatment on markers of bone health in pediatric XLH patients - Obtain a preliminary assessment of the clinical effects of burosumab on bone health and deformity, muscle strength, and motor function - Obtain a preliminary assessment of the effects of burosumab on participant-reported outcomes, including pain, disability, and quality of life in pediatric XLH patients - Evaluate the long-term safety and efficacy of burosumab
The primary purpose of this study is to assess the safety and efficacy of repeated subcutaneous (SC) injections of KRN23 in adult subjects with X-Linked Hypophosphatemia (XLH).
The primary purpose of this study is to assess the safety and efficacy of repeated subcutaneous (SC) injections of KRN23 in adult subjects with X-Linked Hypophosphatemia (XLH). A Bone Substudy will evaluate the effects of single-blind KRN23 versus Placebo on bone mineral density and bone quality.
The primary objective of this study is to assess the safety and tolerability of KRN23 after a single intravenous (IV) and subcutaneous (SC) administration in XLH patients.
