The purpose of this research is to assess the emotional impact on mothers of children with mitochondrial disease (MD). This study plans to compare survey responses between mothers of children with MD caused by mitochondrial DNA (mtDNA) variants, which are exclusively maternally inherited, and nuclear DNA variants (nDNA), which can be inherited from either parent or new in the individual (de novo). This survey also plans to assess the impact on future reproductive decisions due to the fact that reliable preimplantation genetic testing (PGT) for mtDNA variants is lacking and the transmission of mtDNA variants from mother to child is hard to predict.

The purpose of this medical research study is to evaluate the safety and effectiveness of a new medication called imatinib mesylate in the treatment of Lymphangioleiomyomatosis (LAM). LAM is a rare disease in which abnormal cells (called LAM cells) grow out of control. Over time, LAM cells destroy healthy lung tissue and cause respiratory disease or failure.

Many patients with LAM are currently treated with a medication called sirolimus (rapamycin). Sirolimus slows the growth of LAM cells.

Imatinib mesylate (hereafter called imatinib) is approved by the Food and Drug Administration (FDA) for the treatment of some cancers that share common pathways with LAM cells. Laboratory studies suggest that imatinib could completely block the growth of LAM cells through initiation of targeted cell death.

An important purpose of this research is to determine the safety of imatinib in people with LAM. This study will also evaluate the short-term effectiveness of imatinib. Participants will be randomized to receiving imatinib (study medication) or placebo (no treatment) for the 180 day duration of participation. The study is being conducted at the Medical University of South Carolina and at Columbia University in New York (CUMC). Each site will enroll 10 participants.

The purpose of this study is to learn more about long-term safety (good or bad effects) of avacopan and its efficacy (how well it is working) in treatment of antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis.

Avacopan is currently approved as an adjunctive (another treatment used along with primary treatment) treatment in adult people with severe active ANCA-associated vasculitis in the US and is also approved in the EU, Canada, Japan, and other countries.

In this study, avacopan will be compared with a placebo (a drug that looks likes the study medication but does not contain any medication). This is a randomized study, meaning that you will be assigned by chance (like flipping a coin) into a treatment group. You will have an equal chance of being placed in either of the 3 following groups: treatment with avacopan for 5 years in group A, or treatment with avacopan for 1 year followed by placebo for 4 years in group B, or treatment with placebo for 5 years in group C. The study is also a double-blinded study, meaning you and your study doctor will not know what you are receiving, the avacopan or placebo.

The study is sponsored by Amgen, Inc. Participation in the study will require 27 visits to the MUSC main campus over approximately 63 months, and visits will include the following procedures: blood draw, urine collection, physician-led assessments of your disease (for example physical exam and medical history review), and health questionnaires. You will also be provided with a paper diary to record any missed doses/overdoses of the study drug.

Compensation is available for participation.

The main goal of this study is to evaluate how well taking oral elafibranor 80 mg daily works, compared to a placebo, in reducing or preventing the occurrence of death, liver transplant, worsening of liver disease, and liver disease-related complications in adults with PBC.

The purpose of this study is to test whether a drug called NS-229 (the study drug) is a potential treatment for patients with Eosinophilic Granulomatosis With Polyangiitis (EGPA).

NS-229 is an investigational drug that is provided in an oral pill form. An investigational drug is not approved by The US Food and Drug Administration. It can only be used in a research study like this one. In this study, NS-229 will be compared with a placebo (dummy drug), having no active drug in it. This is a randomized study, meaning that you will be assigned by chance (like flipping a coin) to receive either the study drug or placebo. The study is also double-blinded study, meaning you and your study doctor will not know what you are receiving, the NS-229 or placebo.

The study is sponsored by a NS Pharma, Inc. Participation in the study will require 12 visits to the MUSC main campus over approximately 8 months. Visits are much like the your standard of care and include the following procedures: blood draw, urine collection, physician-led assessments of your disease (for example physical exam and medical history review), tests to assess your lung function and health (Pulmonary Function Test (PFT) and spirometry, health questionnaires. You will also be asked to complete a daily diary regarding your medication use and vasculitis symptoms.

The Alpha-1 Foundation Therapeutic Development Network (TDN) aims to make it easier to design and carry out clinical trials that enhance the treatment of patients with Alpha-1 Antitrypsin Deficiency (AATD). To achieve this, the TDN will establish a network of clinical trial centers that have enough patients to gather a comprehensive database of clinical and genetic information. This data will be crucial in determining the criteria for including or excluding participants in the trials and in recruiting suitable subjects.

Specifically, this study will enroll participants by in person or remote consent who will allow collection of medical records to be entered into an Alpha-1 TDN database. Participants will then be invited to future clinical trials.

Hypermobile EDS and hypermobile spectrum disorder (collectively referred to as hEDS) are estimated to affect 1 in 500 individuals worldwide. hEDS patients have limited treatment options for their numerous symptoms that impact the quality of life. This clinical trial tests a new ear stimulation method in hEDS patients to determine if it may improve quality of life.

This is an OLE study for subjects completing from one of two double-blind clinical
trials. Subjects must have completed the Week 13 visit from one of these two parent
clinical trials to be eligible for this OLE.

The purpose of this study is to find out whether a web-based intervention using a mobile app is helpful for teens and young adults with sickle cell disease (SCD) in learning how to care for and manage their symptoms. 272 teens and adults with SCD will be enrolled in this study which is being conducted at the Medical University of South Carolina in Charleston SC., East Carolina University in Greenville NC., University of Miami in Miami FL., and the University of Alabama in Birmingham AL.

This project is an extension of the CDC-funded FORWARD (Fragile X Online Registry With Accessible Research Database) study. From its inception in 2010, the goal of the FORWARD study has been to characterize the natural history of fragile X syndrome (FXS). This current extension project is known as FORWARD-MARCH (Multiple Assessments for Research CHaracterization) because it will include multiple assessments to characterize behavioral, adaptive, and cognitive function in greater depth and thereby further improve understanding of the natural history of FXS. FORWARD-MARCH continues the mission of FORWARD to better understand the natural history of FXS in order to improve the lives of children and adolescents with FXS and the lives of their families. FORWARD-MARCH will also better define trajectories of development in FXS that will be useful in understanding the long-term effects of an intervention relative to the natural history of FXS.

FORWARD-MARCH builds upon the foundation of the FORWARD study. The FORWARD study included 24 participating FXS specialty clinics throughout the US that are members of the FXCRC (Fragile X Clinical & Research Consortium). The FORWARD study worked closely with the Centers for Disease Control and Prevention (CDC), the National Fragile X Foundation (NFXF), and other stakeholders in the FXS community. FORWARD-MARCH will also involve a contractor, Chickasaw Nation Industries (CNI), funded through a contract with the CDC. CNI will assist in data collection and management.

Between September 2022 and August 2026, FORWARD-MARCH expects to enroll at least 600 individuals with fragile X syndrome who were born between 2003-2017. The majority of these individuals will already be FORWARD study participants, enabling researchers to conduct longitudinal analyses incorporating previously collected data. Cognitive, behavioral, and adaptive function will be assessed using parent or caregiver-completed surveys and in-person clinical assessments. After completion of data collection, deidentified data will be securely maintained at CDC and will be an important long-term resource for analyses of the natural history of FXS.

Previous phases of the FORWARD study, conducted between 2012 and 2022, have received IRB review and approval by the institutions of each participating clinic. These previous phases of the study did not require review by a CDC IRB, as CDC had no participant contact and did not have access to personal identifying information (PII). The extension of the FORWARD study covered in this protocol (FORWARD-MARCH, 2022-2026) will continue to be reviewed and approved by the institutions of each participating clinic conducting data collection. However, review and approval are also being sought from the CDC IRB because PII will be maintained on CDC servers and because CDC's contractor, CNI, will regularly have access to PII and interact directly with study participants. A reliance agreement allowing CNI to rely on CDC's IRB is being developed and will be executed before data collection is begun. To clarify which aspects of the protocol involve CDC and CNI staff (rather than just clinic staff), sections 3,4 and 5 of this protocol document each end with a subsection that specifically focuses on the role of CDC and CNI staff.
