Filter by:This is an open-label, dose-escalating study to assess safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and immunogenicity of ALXN1850 when given intravenous (IV) and subcutaneous (SC) to adults with HPP.
Observational study to perform Whole Genome Sequencing in participants clinically suspected for HPP and negative for known pathogenic ALPL variants
Clinical Consequences of Adults Presenting with Hypophosphatasia with Special Focus on Gait, Bone Microstructure and Cognition: The PORTRAIT study Hypophosphatasia (HPP) is an inherited condition that leads to weak bones. Early childhood forms are severe and easily recognized. Adult forms can vary in severity. HPP is often missed by doctors or confused with osteoporosis. This is important because the usual osteoporosis treatments may be harmful to patients with HPP and increase the risk of broken bones. One of the reasons it is missed is a lack of research describing the typical features of HPP, so doctors don't recognize the signs, and don't know when or how to test for it. The PORTRAIT Study will help increase understanding of the burden of disease of HPP on patients. The aim is to examine the effects of HPP on bone structure and strength, physical functioning, cognition, and quality of life. Researchers will study adults with HPP and healthy age- and gender-matched individuals. Blood samples will be collected after an overnight fast. Researchers will use these samples to measure markers of HPP and bone health. Medical history and lifestyle, quality of life and cognitive function will be assessed using questionnaires. Bone mineral density, body composition and bone structure and strength will be measured using dual energy x-ray absorptiometry and high resolution peripheral quantitative computed tomography. Physical functioning will be assessed as participants perform a series of physical performance and gait tests. Magnetic resonance images of the lower limbs will be matched-up with the physical functioning data to create patient-specific musculoskeletal models. Cognitive function tests will be performed to assess cognition and mental health. To reveal the burden of disease of HPP, the data collected from patients with HPP will be compared to that collected from healthy controls.
This observational study will evaluate the treatment effect of Strensiq (asfotase alfa) on Patient Reported Outcomes (PROs) in participants diagnosed with pediatric-onset hypophosphatasia (HPP) registered in the patient support program managed by OneSource™.
The study will evaluate safety, tolerability, efficacy, pharmacokinetics, and pharmacodynamics of 2 different doses (approved dose and lower dose) of asfotase alfa in adult participants with pediatric-onset hypophosphatasia (HPP).
The study aims to evaluate the bone architecture and bone strength in adults with Hypophosphatasia (HPP).
The aim of the study is to accomplish a complete bone status of patients with HPP using new approaches to assess bone quality.
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.
Hypophosphatasia is a rare inherited metabolic disorder due to inactivating mutations of the ALPL-Gene. Particularly among adult patients, clinical manifestation exhibits a broad range of signs and symptoms, most commonly associated with musculoskeletal disabilities and compromised quality of life. Enzyme replacement therapy with Asfotase alfa (AA) is available and approved for patients with pediatric onset of the disease. This single-center observational cohort study aims at collecting clinical routine data regarding the course treatment, quality of life and physical performance in patients treated with Asfotase alfa in line with the label for pediatric-onset hypophosphatasia.
The purpose of this study was to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of asfotase alfa in adult participants with pediatric-onset HPP.
