The purpose of the study is to test new biomarkers of ALS using MRI scans at 3 Tesla (3T). A biomarker is a measurable characteristic that can be used as an indicator of a particular disease state. Identifying biomarkers in ALS will help test new treatments and may help us make diagnoses earlier.

The purpose of this research study is to look at the safety and effectiveness of pritelivir given orally (by mouth for a maximum of 42 days) for people with an impaired immune system who have recurrent lesions caused by the form of HSV that does respond to treatment with acyclovir.

This study is enrolling participants who have been diagnosed with juvenile spondyloarthritis, are taking a tumor necrosis factor inhibitor (TNFi) and have reached a clinically inactive disease state for a minimum of six months. Researchers want to know if children who have maintained inactive disease for at least 6 months can maintain quiet disease without taking their medication as frequently or stop the TNFi therapy. Quiet disease means that disease related symptoms are not active or being experienced in the patient. Researchers also want to know the safest method to bring patients off medication. If a flare does occur during therapy reduction, researchers want to find out whether they can predict when a flare is most likely to happen, and how quickly an inactive disease state can be recaptured.

This study has 2 parts: a double-blind period and an open-label extension. In the double-blind period of this study, the study medicine will be compared to a placebo. A placebo is a treatment that looks and tastes exactly like the study medicine but does not contain any active ingredient. In this study, you will receive leriglitazone or placebo. Whether you receive leriglitazone or placebo will be decided randomly (by chance, like flipping a coin). In this study, 1 out of every 2 subjects (50%) will receive leriglitazone and 1 out of every 2 subjects (50%) will receive placebo. To make this study fair, you and the study doctor will not be told which treatment you will receive, this is called “blinding”. In the open-label extension, all subjects will receive leriglitazone.

The goal of this study is to test the safety and effectiveness of tildacerfont in children with congenital adrenal hyperplasia (CAH). When a child is enrolled in the study, in addition to taking the study drug (tildacerfont), he or she will continue to take his or her standard glucocorticoid doses. A part of the study will be to test different doses of the study drug and to measure adrenal hormones at each visit. Children will be in the study for 18 weeks and will have to visit the study clinic 5 times.

The HEALEY ALS Platform Trial is a research trial that tests the safety and effectiveness of multiple treatments in ALS. A regimen is a specific course of treatment, each with a different study drug. We are doing this research to find out if different treatments have an effect on Amyotrophic Lateral Sclerosis (ALS). We also want to find out if these treatments are safe to take without causing too many side effects.

The purpose of this study is to determine the safety and effectiveness of allogeneic hematopoietic cell transplant in persons with an inherited metabolic disorder or osteopetrosis and if it is effective in reducing or slowing the symptoms associated with the genetic error. The study uses a chemotherapy conditioning regimen that prepares the body to accept the donor hematopoietic cells.

The purpose of the study is to evaluate the use of the Syn-One Test for identifying patients with idiopathic rapid eye movement sleep disorder (iRBD) that will progress to synucleinopathies, such as Parkinson’s disease, dementia with Lewy bodies, pure autonomic failure and multiple system atrophy. Your participation will last approximately 2 years.

In this study, the researchers are collecting blood samples to learn more about laronidase treatment in children that receive a hematopoietic cell transplantation. The laronidase dose regimens used after a hematopoietic cell transplantation may differ from those administered before. This study will establish the basis for determining if there is a need to adjust laronidase dosing regimens after receiving a hematopoietic cell transplantation.

The purpose of this research to enhance our understanding of adrenoleukodystrophy ALD and study biospecimens such assaliva, blood, urine and stool to identify potential biomarkers for early identification of dise. We invite people who have or are at risk to have ALD, including females who are known or at risk carriers of the mutation for ALD, to help us learn more.

PR001A is designed to deliver a normal GBA1 gene copy into the body to increase the activity of GCase, which is low in Type 2 Gaucher Disease (GD2) patients. The new GBA1 gene will remain a child’s body cells for many years and possibly for the rest of their life. A participant will need one surgery during which the study drug will be given and will stay in the hospital for at least 48 hours following the surgery.

The purpose of this study is to evaluate the long-term safety and effectiveness of Skytrofa treatment in children growth hormone deficiency. Patient care will follow the normal treatment practices at the clinic. No additional visits will be performed beyond the usual clinical practice.

The purpose of this study is to establish a registry and biobank to study monoclonal gammopathy and amyloidosis. We aim to understand better the changes these diseases cause, the symptoms they present, and the clinical progression to be able to better prevent them and treat them in the future.

This is a long-term registry is designed to collect data on hypophosphatasia (HPP) to better understand the condition and learn more about the disease, how patients feel about living with HPP and effect of HPP on the patients wellbeing and health. The study will look at participant’s medical records and health questionnaires about the health status of patients. This study collects observational data from clinical care and does not involve any treatment for HPP or administration of medication for HPP.

The purpose of the study is to test new biomarkers of amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS) using MRI scans at 3 tesla (3T). Identifying biomarkers of a disease can lead to a better understanding of the disease as well as improved treatments.

This research is being completed to examine the cells, brain imaging, and speech in individuals with REM Sleep Behavior Disorder who are taking serotonergic medications such as Citalopram, Escitalopram, Fluoxetine, Fluvoxamine, Paroxetine and Sertraline. The purpose of examining these is to try and see if we can predict signs of Dementia with Lewy bodies (a progressive form of dementia with an increase in decline of thinking, reasoning, and other functions). This may benefit others by enabling us to diagnose Dementia with Lewy Bodies sooner rather than later.

This is a global, multicenter, prospective, observational, longitudinal registry conducted to characterize the natural history and real-world clinical management of patients diagnosed with AHP. This protocol will not recommend the use of any specific treatments, visits, or procedures. No medication is provided as part of registry participation.

The purpose of this study is to test a new drug, called ST-920, to see if it is safe and if it works to treat Fabry disease. ST-920 is a gene therapy treatment, which means that ST-920 replaces the missing or broken gene you have because you have Fabry disease, with a version or copy that works.

A single visit study with muscle and/or skin biopsy / blood draw, performed to determine whether a molecular or cellular defect can be attributed to cells of Fascioscapulohumeral Muscular Dystrophy (FSHD) muscle. This study is recruiting both individuals with genetically confirmed FSHD as well as unaffected healthy (control) individuals.

This study is about a genetic condition called Adrenoleukodystrophy (ALD). The first goal of this study is to understand more about how ALD affects a child’s brain and development in childhood as they take part in medical care and monitoring. This is important to identify the optimal ways to detect and treat manifestations of ALD such as cerebral ALD. The second goal is to learn about how ALD affects caregivers, so that clinicians can offer better support to families in the future. We will also have healthy comparisons to help to learn more about the condition (ALD) being studied, by comparing the information collected to a child without the condition.

The purpose of this study to learn more about Limb Girdle Muscular Dystrophy by measuring how muscles change over a twelve-month period. Our clinical evaluator will test muscle strength and participants will be asked to complete a series of questionnaires to find out how Limb Girdle impacts daily activities. This information will help plan future studies and drug development for people with LGMD.

We are doing the RARE study to learn more about Cystic Fibrosis (CF). CF is caused by mutations in a gene that produces a protein called the cystic fibrosis transmembrane conductance regulator (CFTR). In people with CF, the CFTR does not function correctly. Medications are being developed to help the CFTR function better, but those medications mostly benefit people with common CFTR mutations. There are more than 1,900 mutations of the CF gene. Some of these mutations are rare and found only in a few people. The goal of this research study is to collect specimens (blood, nasal cells, rectal cells) from people with rare CFTR mutations. Another purpose of this study is to create induced pluripotent stem cells or iPS cells. “Pluripotent” stem cells are cells that can be changed into almost any cell type of the body (such as lung or intestine). They can be kept alive and stored indefinitely. There are different kinds of pluripotent stem cells. Inducted pluripotent stem cells can be created from many different kinds of specimens (such as blood, nasal cells, rectal cells). This is different from embryonic stem cells, which can only be derived from embryos. The specimens collected during this study and iPS cells created from them will be stored for use in future research to learn more about CF and study the effect of new medications. This could identify new medications that may help people with rare CFTR mutations.

This research is being done to help us better understand the different DNA repair disorders. We will collect data and samples that we will use to develop new therapies and medicine to help treat the disease. We expect that participants will be in this research study for 3 years. Visits will occur every six months and alternate between in-person and remote. Remote visits should be expected to last 1-2 hours, and in-person visits should be expected to last 3-4 hours.

The purpose of this study is to measure levels of blood and brain chemicals related to oxidative stress and inflammation in healthy volunteers and individuals with Type 1 Gaucher disease (GD1) to see if these levels are altered by GD1. We will also examine if there is a change in these blood and brain chemicals after participants begin taking oral N-acetylcysteine (NAC), which is available both as a prescription medication and a natural product that has antioxidant and anti-inflammatory effects.
