The Syner-G regimen research study seeks to evaluate the use of a combination of a medication called miglustat and a ketogenic diet for treatment of the gangliosidoses to learn if this combination will provide improved clinical outcomes compared to what we currently know about the natural course of the disease.

This is a research study documenting the natural history of disease in patients with GM1 or GM2 gangliosidosis. The information collected will be a way to evaluate disease progression and create a disease stage and severity index. Our goal is to use the data collected to measure the effectiveness of any treatments that are developed in the future.

The effect of enzyme replacement therapy on how well your kidneys are responding to enzyme replacement therapy (ERT) is not clear from blood and urine tests alone, but may be more clear in comparisons of kidney biopsies performed before and some time after ERT has been initiated, and this is what we are focusing our study efforts on. The purpose of this study is to obtain your permission to allow us to study the kidney biopsy tissues (collected for medical reasons) after the regular routine studies have been completed. Through our special research measurements and additional study, we hope to be able to see and measure very specific changes in the kidney tissues from Fabry patients taking ERT. We also hope that through these studies of what happens within the kidney before and after starting ERT, we are able to reveal valuable information about the importance of factors like your age that you started ERT, the amount or dosage of ERT, and any differences seen between males and females.

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.

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.

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.

The DELIVER-MS study seeks to answer the important question: Does early treatment with highly effective DMT improve the prognosis for people with MS? This is an area of significant controversy and no data currently exist to guide treatment choices for patients and clinicians. The study results will help guide overall treatment philosophy and will be applicable not only to a wide range of existing therapies but also to new therapies, meeting a significant unmet need in patient decision making and aiding the decision for medication approval by third parties.

This is a study to assess the safety and efficacy of PR001A, an Aden-associated (AAV9) viral vector to treat neuronopathic Gaucher disease type 2 (GD2) in infants. PRA001A will be administered via suboccipital injection to the cisterna magna during a single neurosurgical session. GD2 is a fatal disease of early infancy that does not have any therapeutic options beyond palliative care. This study will enroll infants 0-24 months of age.

The objective is to conduct a longitudinal investigation of the natural history, complications, and therapeutic outcomes in people with acute and cutaneous porphyria.

The purpose of this study is to investigate how effective and safe ZYN002, a transdermal gel, is in participants with FXS. The drug product ZYN002 is a pharmaceutically manufactured CBD. It is being developed as a clear gel that can be applied to the skin (called transdermal delivery), to provide consistent, controlled levels of CBD in the blood when it is given twice a day. Participants will be assigned by chance to get one of the following study treatments: Active study drug – ZYN002 or placebo. Assigning study drug by chance is called “randomization,” and it is an important part of testing an experimental study drug. Participants will be randomly assigned to study treatment according to a computer program and will have 1 in 2 chance of receiving the active study drug.

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.

This is a two-part, multi-center, prospective longitudinal, exploratory study of highly effective CFTR modulators and their impact in children with CF on endocrine growth factors, the gut microbiome, respiratory microbiome, liver and pancreatic function, lung function, sweat chloride, and inflammatory markers.

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 is a prospective, multi-center, observational study in pregnant women with cystic fibrosis (CF) to characterize forced expiratory volume in 1 second (FEV1) changes based on exposure to highly effective cystic fibrosis transmembrane conductance regulator (CFTR) modulators. The key factors contributing to the change in lung function during pregnancy and for 2 years post-delivery will be evaluated along with assessment of fetal and maternal outcomes.

We are comparing the results of stool sample testing to colonoscopy for people who have Cystic Fibrosis (CF). We want to find out how effective stool sample testing is in detecting adenomas, including colorectal cancer.

This is a single center, open label, Phase I clinical trial of bioactive curcumin with high phenolic extra virgin olive oil (HP-EVOO) to treat cutaneous neurofibromas (cNF) in Neurofibromatosis, type 1 (NF1) patients (aged 18 years or older).

We are studying a new medication, namilumab, given to treat Chronic Pulmonary Sarcoidosis. We are looking at the effectiveness, how well the drug is tolerated, and the side effects that occur. For the first part of the study, some people will receive the namilumab; the others will receive an inactive (placebo) drug. In the second part of the study, everyone may receive the namilumab.

We are looking at a new intravenous drug, Bacteriophage, to treat Pseudomonas Aeruginosa in people at least 18 years of age who have cystic fibrosis. The drug is given one time and different doses will be evaluated to see if they work and to look at side effects.

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 the study is to see if the drug (BIVV020) works to improve symptoms in three populations of adults who have chronic inflammatory demyelinating polyneuropathy (CIDP): • Participants currently on the standard of care (SOC) treatment. • Participants treated previously with the SOC but with no meaningful improvement. • Participants that have not been treated with the SOC. Additional purposes of the study are to find out how safe and tolerable the drug is.
