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.

Tetra Discovery Partners, Inc. has two studies that are recruiting males aged 9 to 45 to participate in a treatment clinical trial for Fragile X Syndrome. The treatment, called BPN14770, is a phosphodiesterase inhibitor that has the potential to address cognitive and neurological impairment in those with Fragile X Syndrome.

BPN14770-CNS-301 is a clinical trial for males aged 18 to 45 with Fragile X Syndrome. It is double-blind, meaning that neither the study doctor nor the enrolled participants know whether or not they are receiving study drug or placebo. A placebo is an inactive material that looks like the study drug, but does not contain any active study drug.

The main goals of this study are to learn how well the study drug works and how safe the study drug is compared with placebo.

After completing the double-blind study, participants have the opportunity to enroll in the open-label extension of this clinical trial, called BPN14770-CNS-302; "open-label" means that the study doctor and participants are all aware that participants are definitely getting the study medication.

This study is designed to learn about the safety and effectiveness of a new gene therapy called KB408 for Alpha-1 Antitrypsin Deficiency (AATD). AATD is an inherited condition in which a person has low blood levels of a protein known as alpha-1 protease inhibitor (called Alpha1-PI). AATD causes an increased risk of chronic obstructive pulmonary disease (COPD) in the form of emphysema (long term lung disease) and, less frequently, other diseases.
KB408 delivers copies of the genes that produce AAT to the lungs and is given by inhaling a mist (called nebulization). The genes are carried and delivered by a modified herpes simplex virus type 1 (HSV-1). This virus is not harmful and simply acts as a vehicle to deliver the genes to the lungs. The genes that are delivered by KB408 do not change a person's own DNA. This is an open-label study, meaning that the participants, the study doctor, and the sponsor all know that the participants are receiving KB408. KB408 is an investigational product, meaning it is not approved for commercial use by the FDA.
Eligible participants will receive one of three doses of KB408. Participants will have a screening visit first to make sure that they are able to participate in the study. After the screening visit, participants will need to return to the study center 6 more times over 2 months. At the second visit, participants will receive the study drug. Each visit will take between 2 and 6 hours to complete. Study procedures include medical history collection, vitals, physical exam, ECG, spirometry and DLCO, urine cotinine test, blood work, cheek swab, sputum sample, and bronchoscopy (only for participants in cohorts 3a and 3b).
Possible side effects of KB408 include temporary increases in certain cell types in the lungs and temporary increases in the breathing rate after dosing. Since this is the first time that KB408 has been given to humans, it is possible that participants may have an immune reaction to the study drug. There is also a risk with genetic testing and a risk to confidentiality. Participants may not receive any personal benefit from being in this study. There is no guarantee that the Study Drug will help. The information that is collected from the study may help other people in the future.

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.

Over 2400 people who have sickle cell disease and are between the ages of 15 and 45 have been enrolled into the National Registry (SCDIC-I) of patients with Sickle Cell Disease (SCD). A rich resource of natural history data, the SCDIC-I Registry has longitudinal data collected yearly since 2016 from patient surveys (e.g. self reported pain incidences, sleep, barriers to care, experiences during and after pregnancy), medical record abstraction (e.g. medications, transfusion history, co-morbidities) and laboratory results. The 150 patients (or 1200 among the 8 sites) will be selected from both MUSC adult and pediatric SCD clinics starting at 12 years of age; those not previously enrolled in the SCDIC National Registry will be offered the possibility to enroll in SCDIC-II.
We will look at the following:
1- Compare the effect of new SCD medications – crizanlizumab, voxelotor, and L-glutamine – on clinical outcomes in individuals with SCD.
2 - Identify genetic and genomic predictors of response to crizanlizumab, voxelotor, and L-glutamine
3 - Integrate study data into the CureSCi metadata catalog (MDC) to enhance future cross-study analyses.

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.

This is a 3-part study, with each part having a unique set of objectives for male
adolescents aged 12 to < 18 years with fragile X syndrome (FXS). Part 1 is an openlabel,
single-dose, pharmacokinetics (PK) assessment of BPN14770 25 mg and
50 mg; Part 2 is double-blind (DB) and randomized; and Part 3 is an open-label
extension (OLE) for patients who complete Part 2.

This randomized, double-blind, placebo-controlled Phase 2/3 adaptive study involves an initial investigational blood test to determine if you have a specific variation related to kidney disease. The investigational blood test is to see if you have changes in your DNA of a gene called APOL1. People who have this gene variation may be at risk of losing their kidney function faster than others. If you have the variants (changes in DNA) you may be eligible to continue participation in the study. If you do not have the variants, you will not be eligible, and the study doctor will discuss your other options with you. If you decide to participate, there will be no cost to you and you will be compensated. This study will start by comparing two doses of VX-147 against placebo in subjects with APOL1-mediated kidney disease for 12 weeks. Subjects in Phase 2 will continue to Phase 3 once a dose for Phase 3 is selected. Then the Phase 3 dose of VX-147 will be evaluated for safety and effectiveness. If you meet the requirements and choose to take part in the study, you will be randomly assigned to a treatment group. You will not know which study treatment group you are assigned to and it is possible that you will receive placebo instead of VX-147. The study includes a screening, treatment, and follow-up period. The study will end after the last patient enrolled has completed 2 years in the study. This means some patients enrolling earlier could be in the study for up to 4 years.

The purpose of this research study is to develop a better understanding of the cause and natural history of vascular anomalies and related syndromes. This study is being done in order to develop a better understanding of the cause of vascular anomalies in order to to improve care for people who are affected by these anomalies and related syndromes.

This study is being done at the University of Wisconsin-Madison (UW-Madison) and other sites in North America and Europe. A total of about 1000 people will participate in this study. About 20 – 30 people will take part in the study here at the Medical University of South Carolina.

The purpose of this project is to study DNA and its connection to your health. DNA is in your blood, your saliva, and other tissues in your body. DNA is the unique instructions you are born with that tells your body how to work. By looking at DNA, you can learn information about your health, certain traits, and even your ancestral roots. DNA is also called your genetic information. DNA is mostly the same from person to person. But everyone's DNA is slightly different. We are still learning how DNA impacts health. This study will look at the DNA of many different people from many different backgrounds and compare it to information in their health records. The goal is to understand how learning about DNA can help improve health care for individuals, families, and the community.

Participants will provide a sample for DNA sequencing. Sequencing is the process of reading the letters of your DNA. This study may sequence your whole genome. Over time, you may be asked to provide additional samples for research purposes. The research team will collect health information about you from your medical record and may ask you questions about your health using surveys or other data collection method.
