Active clinical trials for "Niemann-Pick Diseases"

The goal of this research study is to establish chimerism and avoid graft-versus-host-disease (GVHD) in patients with inherited metabolic disorders.

Due to different study designs, the sponsor separated Part C into this separate registration (NCT04958642), leaving Parts A/B in NCT02534844. The trial's final results for the primary outcome measure of Adverse Events (AE) will be reported here. This study is to evaluate how safe and effective adrabetadex is for participants with Niemann-Pick Type C1 (NPC1) disease who experience neurologic symptoms (listed under Keywords). In Parts A/B (NCT02534844), two out of every 3 participants will receive the study drug. The third participant will receive 1 to 2 small needle pricks at the location where the IT injection is normally made (sham control). In Part C, all participants will receive study drug.

The purpose of this study is to determine the safe range of single doses of rhASM administered to adults with ASM deficiency.

The primary objective of this study is to obtain data regarding the safety of olipudase alfa in patients with acid sphingomyelinase deficiency (ASMD) who are exposed to long term treatment with olipudase alfa. The secondary objectives of this study are to obtain data regarding the efficacy of olipudase alfa and to characterize olipudase alfa pharmacodynamics (PD) and pharmacokinetics (PK) following long-term administration.

To evaluate the changes in cognitive function after miglustat treatment in Niemann-Pick type C patients.

To evaluate the safety, tolerability, pharmacokinetic, and pharmacodynamic profile of rhASM in adult patients with Acid Sphingomyelinase Deficiency (ASMD) following repeated-dose administration.

Background: - Hydroxypropyl beta cyclodextrin (HPBCD) is being tested for a disease called Niemann-Pick disease type C1 (NPC1). NPC1 is a genetic disorder that results in gradual loss of nervous system function. Cholesterol and other fats have trouble moving out of the brain cells, which makes the cells work poorly and leads to symptoms. There is no treatment currently approved in the US for NPC1. Researchers want to test if it is safe to use HPBCD for NPC1. They want to see if it can help brain cells process cholesterol better. Objectives: - To test the safety and effectiveness of HPBCD for NPC1. Eligibility: - Individuals between 2 and 25 years of age who have been diagnosed with NPC1 and who have not already received HPBCD in an attempt to treat NPC1. Design: Participants will be screened with a physical exam and medical history. They will provide blood and urine samples for screening. They will also have neurological tests, including tests of hearing, speech and movement. Participants will have a lumbar puncture (also called a spinal tap) every month to deliver the drug to the spinal fluid that surrounds the brain. The length of the trial will be determined by the safety and efficacy information that is obtained. Treatment will be monitored with frequent blood and urine tests, cerebral spinal fluid tests, hearing and neurological exams.

Due to different study designs, the sponsor separated Part C into a separate registration (NCT04958642), leaving Parts A/B here in NCT02534844. This study is to find out how safe and effective VTS-270 is for patients with Niemann-Pick Type C1 (NPC1) disease who have neurologic symptoms (listed under Keywords). In Parts A/B, two out of every three patients will receive the study drug. The third patient will receive 1 to 2 small needle pricks at the location where the LP and IT injection is normally made (sham control). In Part C, all participants will receive study drug, as described in the Part C registration record. Start date for this record is the first day a participant was enrolled in Parts A/B. The trial is actually continuing until the last primary outcome measure of safety data are collected from Part C participants. The last primary outcome measure of safety, along with final adverse events results will be posted in the separate Part C registration record.

Niemann-Pick disease type C (NPC) is a lethal, autosomal recessive, lysosomal storage disorder characterized by neurodegeneration in early childhood and death in adolescence. The causative genes NPC1 (about 95% of cases) and NPC2 (about 5% of cases) are involved in the intracellular trafficking of lipids and cholesterol. Mutations on either of these genes lead to progressive accumulation of unesterified cholesterol and other lipids in the central nervous system (CNS). Vorinostat is a histone deacetylase inhibitor that has been shown in vivo to increase mutant NPC1 protein levels and to reverse cellular accumulation of unesterified cholesterol. Vorinostat has been labeled by the FDA for treatment of cutaneous T-cell lymphoma. In this Phase I, non-randomized, open-label, single-center study, we plan to study whether Vorinostat can be repurposed to treat patients with NPC1. Our primary objective is to determine the safety and tolerability of Vorinostat in NPC1 disease. Our secondary objectives will be to determine biochemical efficacy of Vorinostat to increase expression of NPC1 protein and normalize lipid and protein biomarkers. This study will enroll up to 12 NPC1 patients and test the safety of two dose levels (200 and 400 mg). Drug will be administered on a 3 days on/4 days off schedule for 3 months at each dose level. Patients will be evaluated at the NIH Clinical Center at 0, 3 and 6 months. Safety will be assessed by adverse events (AEs), clinical laboratory tests and physical examinations. Biochemical efficacy will be assessed by measurement of serum and cerebral spinal fluid biomarkers. Clinical efficacy will be evaluated by audiologic testing, assessment ataxia, and swallowing studies.

This is a clinical trial of bone marrow transplantation for patients with the diagnosis of a genetic disease of blood cells that do not have an HLA-matched sibling donor. Genetic diseases of blood cell include: Red blood cell defects e.g. hemoglobinopathies (sickle cell disease and thalassemia), Blackfan-Diamond anemia and congenital or chronic hemolytic anemias; White blood cells defects/immune deficiencies e.g. chronic granulomatous disease, Wiskott-Aldrich syndrome,Osteopetrosis, Kostmann's syndrome (congenital neutropenia), Hereditary Lymphohistiocytosis (HLH); Platelets defects e.g.Congenital amegakaryocytic thrombocytopenia; Metabolic/storage disorders e.g. leukodystrophies,mucopolysaccharidoses as Hurler disease;Stem cell defects e.g.reticular agenesis, among many other rare similar conditions. The study treatment plan uses a new transplant treatment regimen that aims to try to decrease the acute toxicities and complications associated with the standard treatment plans and to improve outcome The blood stem cells will be derived from either unrelated donor or unrelated umbilical cord blood.
