NCT ID: NCT06190626 Recruiting - Clinical trials for Zellweger Spectrum Disorder

Longitudinal Prospective Natural History Study of Retinopathy in Zellweger Spectrum Disorder

ZSDvision
Start date: December 18, 2023
Phase:
Study type: Observational

The goal of this observational study is to define the course of the retinal degeneration in a ZSD patient cohort. The objective of this study is to gather information so the investigators can: 1. define the course of the retinal degeneration in a ZSD patient cohort with retinal degeneration 2. define what tests best monitor the progression of the retinal degeneration 3. generate prognostic information about vision loss in ZSD. At each yearly visit, the participants will answer a functional vision questionnaire, have a physical evaluation, blood test, and participate in a variety of vision tests. The investigators will also collect pertinent medical history. Participants will travel to study site. The study will provide financial support for board and travel.

NCT ID: NCT03856866 Completed - Zellweger Syndrome Clinical Trials

Hydroxychloroquine Administration for Reduction of Pexophagy

HARP
Start date: January 11, 2019
Phase: Phase 2
Study type: Interventional

A series of N-of-1, crossover, randomized, placebo-controlled, double-blinded trial. Hydroxychloroquine (HCQ) and a crossover to placebo (order is randomized and blinded) will be administered in liquid suspension for 84 days (12 weeks) each with an 84 day washout in between. We hypothesize that HCQ will reduce peroxisomal turnover, which will arrest ongoing injury in PBDs caused by PEX1, PEX6 or PEX26.

NCT ID: NCT03440905 Completed - Zellweger Spectrum Clinical Trials

Proxy-Reported Symptoms and Quality of Life Survey in Zellweger Spectrum Disorders

Start date: January 29, 2018
Phase:
Study type: Observational

The purpose of this study is to characterize the symptoms of Zellweger Spectrum Disorder (ZSD) and related peroxisome disorders, and to assess the quality of life of family caregivers (parents, stepparents, legal guardians) of patients diagnosed with ZSD or a related peroxisome disorder. All family caregivers of patients enrolled in the Rare Diseases Clinical Research Network (RDCRN) Contact Registry who are diagnosed with ZSD or a related peroxisome disorder will be invited via email to participate in this study.

NCT ID: NCT03047369 Recruiting - Clinical trials for Adrenoleukodystrophy

The Myelin Disorders Biorepository Project

MDBP
Start date: December 8, 2016
Phase:
Study type: Observational [Patient Registry]

The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future.

NCT ID: NCT02699190 Active, not recruiting - Clinical trials for Adrenoleukodystrophy

LeukoSEQ: Whole Genome Sequencing as a First-Line Diagnostic Tool for Leukodystrophies

Start date: January 6, 2017
Phase:
Study type: Observational

Leukodystrophies, and other heritable disorders of the white matter of the brain, were previously resistant to genetic characterization, largely due to the extreme genetic heterogeneity of molecular causes. While recent work has demonstrated that whole genome sequencing (WGS), has the potential to dramatically increase diagnostic efficiency, significant questions remain around the impact on downstream clinical management approaches versus standard diagnostic approaches.

NCT ID: NCT02171104 Recruiting - Hunter Syndrome Clinical Trials

MT2013-31: Allo HCT for Metabolic Disorders and Severe Osteopetrosis

Start date: July 10, 2014
Phase: Phase 2
Study type: Interventional

This single-institution, phase II study is designed to test the ability to achieve donor hematopoietic engraftment while maintaining low rates of transplant-related mortality (TRM) using busulfan- and fludarabine-based conditioning regimens with busulfan therapeutic drug monitoring (TDM) for patients with various inherited metabolic disorders (IMD) and severe osteopetrosis (OP).

NCT ID: NCT01668186 Recruiting - Clinical trials for RCDP - Rhizomelic Chondrodysplasia Punctata

Longitudinal Natural History Study of Patients With Peroxisome Biogenesis Disorders (PBD)

Start date: January 2012
Phase:
Study type: Observational

The Peroxisome Biogenesis Disorders (PBD) are a group of inherited disorders due to defects in peroxisome assembly causing complex developmental and metabolic sequelae. In spite of advancements in peroxisome biology, the pathophysiology remains unknown, the spectrum of phenotypes poorly characterized and the natural history not yet systematically reported. Our aims are to further define this population clinically, biochemically and genetically. The investigators will prospectively follow patients from Canada, the US and internationally, and collect data from medical evaluations, blood, urine and imaging studies that would be performed on a clinical care basis. For patients who are unable to attend our clinic, we will collect all medical records and images since birth as well as subsequent records/images for the next 5 years or until the end of the study. Clinical data from medical records will be banked in our Peroxisomal Disorder Research Databank and Biobank. The investigators will use this information to identify standards of care and improve management.

NCT ID: NCT00007020 Completed - Cholestasis Clinical Trials

Compassionate Treatment of Patients With Inborn Errors of Bile Acid Metabolism With Cholic Acid

Start date: January 1992
Phase: Phase 3
Study type: Interventional

OBJECTIVES: I. To Evaluate the therapeutic efficacy of cholic acid during provision of compassionate treatment to patients with identified inborn errors of bile acid synthesis and metabolism II. To assess the safety and tolerability of cholic acid

NCT ID: NCT00004442 Terminated - Clinical trials for Adrenoleukodystrophy

Study of Bile Acids in Patients With Peroxisomal Disorders

Start date: n/a
Phase: N/A
Study type: Interventional

OBJECTIVES: I. Determine the effectiveness of oral bile acid therapy with cholic acid, chenodeoxycholic acid, and ursodeoxycholic acid in patients with peroxisomal disorders involving impaired primary bile acid synthesis. II. Determine whether suppression of synthesis of atypical bile acids and enrichment of bile acid pool with this regimen is effective in treating this patient population and improving quality of life.
