Filter by:The aim of this study is to evaluate nedosiran in participants 11 years of age and younger who have Primary Hyperoxaluria with relatively intact renal function.
The purpose of this study is to describe the natural history and progression of patients diagnosed with PH1, and to characterize the long-term real-world safety and effectiveness of lumasiran.
The aim of this study is to evaluate DCR-PHXC in participants with PH1 or PH2 and severe renal impairment, with or without dialysis.
The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics (PK), and pharmacodynamics (PD) of lumasiran in patients with Advanced Primary Hyperoxaluria Type 1 (PH1).
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
The purpose of this study is to identify unique urine protein markers of Primary Hyperoxaluria type 1 (PH1) compared to healthy controls. Urine protein markers can be identified by "proteomic" analyses in which proteins are processed in a lab to break them down into smaller building blocks. Using analytical chemistry techniques and specialized equipment many proteins can be identified and measured. Most proteins are found in healthy living cells while subtle changes in these proteins or the presence of different markers reflect abnormal processes and patterns of disease. When identified in disease, protein biomarkers can help to determine if a disease responds to new types of therapies. In this study, changes in urine proteomic patterns over time, their association with change in estimated (calculated) kidney filtering function, and the relative risk for progression of PH1 will be determined. Additionally, as part of the study, the investigators will measure urinary proteins and peptides that are markers of kidney tissue protection (for healthy healing of the kidneys from ongoing damage from high urine oxalate levels, oxalate crystals and stones) to establish if and when these markers are prospectively decreased in PH1 urine. Longitudinal studies of urine "proteomics" may assist in identifying the mechanisms behind PH1-related progression of kidney failure and might contribute important information towards future identification and development of effective therapies to slow or prevent kidney failure in PH1.
The aim of this study is to know the difference between protein profiles (multi-analyte profile) of PH1 patients, idiopathic hypercalciuria (IH) patients and PH1 patients 'siblings. Idiopathic hypercalciuria is a less severe kidney disease that PH1, which also leads to the formation of kidney stones. The aim is to identify patterns of discriminating markers associated with primary hyperoxaluria type 1 (PH1) that will significantly improve clinical diagnosis and prognosis.
A phase 1 study of DCR-PH1 in patients with primary hyperoxaluria type 1 (PH1) to determine the safety, tolerability, pharmacokinetic (PK) and pharmacodynamics (PD) effects of DCR-PH1 administered via-intravenous infusion (IV)
