Active clinical trials for "Gaucher Disease"

Recent studies have has shown that magnetic resonance spectroscopy (MRS) can provide validated neuronal markers in patients with Type 1 GD (GD1) who are on stable therapy. However, alterations in neurometabolites in adult patients with GD3, who have established neurological involvement, are not well understood. The goal of this study is to characterize neurometabolite profiles in adult patients with GD3 using MRS to identify novel biomarkers that can demonstrate treatment response. Additionally, a secondary aim is to evaluate relationships between neurometabolites and disease parameters, such as genotype, enzyme levels and Gaucher disease (GD) biomarkers.

ScreenPlus is a consented, multi-disorder pilot newborn screening program implemented in conjunction with the New York State Newborn Screening Program that provides families the option to have their newborn(s) screened for a panel of additional conditions. The study has three primary objectives: 1) define the analytic and clinical validity of multi-tiered screening assays for a flexible panel of disorders, 2) determine disease incidence in an ethnically diverse population, and 3) assess the impact of early diagnosis on health outcomes. Over a five-year period, ScreenPlus aims to screen 175,000 infants born in nine high birthrate, ethnically diverse pilot hospitals in New York for a flexible panel of 14 rare genetic disorders. This study will also involve an evaluation of the Ethical, Legal and Social issues pertaining to NBS for complex disorders, which will be done via online surveys that will be directed towards ScreenPlus parents who opt to participate and qualitative interviews with families of infants who are identified through ScreenPlus.

The purpose of this study is to identify genetic, biochemical, and clinical factors that are associated with disease severity in people with Gaucher disease and other lysosomal storage disorders. There is a vast spectrum of clinical manifestations in people with Gaucher disease as well as other lysosomal storage disorders. This study will evaluate patients with lysosomal disorders on an outpatient or inpatient basis in order to better characterize the clinical, genetic, and pathophysiological features of these disorders. Participants will be re-evaluated on an annual basis.

Ambroxol is expected to improve the signs and symptoms of patients with Type I Gaucher Disease.

This is an observational study intended to generate preliminary data to understand how lysosomal dysfunction can affect the biogenesis of extracellular vesicles, its content and function. The primary objective of the proposed project is to decipher how extracellular vesicle (EV) biogenesis and its role in intercellular communication can be impaired as a consequence of defects in lysosomal function. Collectively these defects in EV biogenesis and function can contribute to the neuroinflammation observed in lysosomal storage diseases. Since EVs can cross the blood-brain barrier, their characterization may be valuable in identifying novel biomarkers. In the presence of a GBA1 mutation, the decrease in GCase activity will lower overall lysosome function and increase the secretion of EVs. Further, there will be differences in EV size, its cargo including lipids, RNA and proteins and their aggregates. In comparison to healthy controls, EVs isolated from patients with Gaucher disease (GD) and GBA1 carriers is hypothesized to show significant differences in terms of its characteristics and content, which can contribute to our understanding of the link between lysosomes and neurological disease.

The purpose of this research is to review data already collected and to collect new data from adults and children in England with Gaucher Disease to determine clinical factors which predict severity and response to therapy of Gaucher disease especially in the areas of bone, cancer and brain conditions.

The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate Parkinson's disease research and drug development by using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and/or store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for Parkinson's disease.

The study of splenomegaly, and the follow-up of splenectomized patients, is one of the causes of referral of these patients to pediatric gastroenterology and oncohematology clinics, and adult internal medicine and hematology. The study and management of splenomegaly is well described among the different medical specialties to which these patients arrive. After the application of the different algorithms and the different studies that are carried out, these splenomegaly are identified as being of hepatic, infectious, inflammatory, congestive, hematological origin and primary causes. Despite these studies of splenomegaly, approximately 10-15% of these patients still remain undiagnosed. Several studies have suggested that there is an increased frequency of MGUS (monoclonal gammopathy of undetermined significance) and/or multiple myeloma (MM) among Gaucher patients. Regarding ASMD (Acid Sphingomyelinase Deficiency), few studies have been published but it seems the 21% of patient with ASMD has MGUS and 15% ASMD patients have MGUS. Moreover, patients with MGUS and Gaucher disease (GD) are at increased risk of developing MM. The objective of the present study is to increase the diagnostic sensitivity of these unknown splenomegalys, or unknown splenomegaly patients with MGUS or multiple myeoloma who remain in consultations, using the usual diagnostic clinical procedures of unknown splenomegaly and unknown splenectomy patients, where we include the extraction of a blood sample for dry drop test (DBS), where the determination of the enzymatic/genetic activity will be carried out for Gaucher disease (GD) and acid sphingomyelinase deficiency (ASMD) , analysis of LisoGl1 and LisoSM.

The study of splenomegaly, and the follow-up of splenectomized patients, is one of the causes of referral of these patients to pediatric gastroenterology and oncohematology clinics, and adult internal medicine and hematology. It has been described that 0.3% of hospital admissions is for this reason. The study and management of splenomegaly is well described among the different medical specialties to which these patients arrive. After the application of the different algorithms and the different studies that are carried out, these splenomegaly are identified as being of hepatic, infectious, inflammatory, congestive, hematological origin and primary causes. Despite these studies of splenomegaly, approximately 10-15% of these patients still remain undiagnosed. The objective of the present study is to increase the diagnostic sensitivity of these unknown splenomegalys, or unknown splenomegaly patients who remain in consultations, using the usual diagnostic clinical procedures of unknown splenomegaly and unknown splenectomy patients, where the investigators include the extraction of a blood sample for dry drop test (DBS), where the determination of the enzymatic/genetic activity will be carried out for Gaucher disease (GD) and acid sphingomyelinase deficiency (ASMD) , analysis of LisoGl1 and LisoSM.

Primary Objective: To assess prevalence of Gaucher disease (GD) diagnosed in pediatric patients presenting with unexplained splenomegaly (SMG) after exclusion of first intention-diagnoses (e.g. portal hypertension, haematological malignancy, hemolytic anemia, infection) based on clinical examination and routine biological tests (full blood count, reticulocytes, liver tests, abdominal ultrasound, Coombs test and Epstein Barr virus serology). Secondary Objectives: To describe the rate of each identified disease category and the rate of patients with no final diagnosis at the end of the study in pediatric patients with unexplained SMG after exclusion of first intention diagnoses To describe the characteristics (clinical, lab, genetics) of all pediatric patients included in the study and to describe the characteristics subdivided by identified disease category and absence of final diagnosis at the end of the study
