This study includes a longitudinal mixed methods study of 360 YYA with diabetes in SC, CO, and WA conducted with SFS 1 participants. SFS 2 will have two parts: (1) an intense, longitudinal study consisting of two 14-day assessment periods spaced 9 months apart which will include CGM, EMA, accelerometry, and surveys in all participants (the EMA study); and (2) a concurrent events qualitative study with a subset of participants (30 T1D, 15 T2D) who will complete 13 one-on-one, semi-structured interviews throughout the 9-month assessment period (the qualitative study).

This study will evaluate the safety and effectiveness of fazirsiran (investigational drug) compared with placebo (an inactive substance) in patients with alpha-1 antitrypsin deficiency associated liver disease (AATD-LD). If eligible, subjects will be randomized (assigned to a group by chance) to receive either fazirsiran or placebo to be administered subcutaneously (an injection under the skin). Subjects will be treated on Day 1, at Week 4, and then every 12 weeks for 196 weeks. Subjects will be followed for 6 months after their last dose of study drug or placebo for a total study duration of approximately 230 weeks (including 10 weeks of the screening period which is the time needed to assess if a subject is eligible for the study).

The purpose of this study is determine the optimal dose, efficacy and safety of an investigational drug (a new drug not yet approved by the U.S. Food and Drug Administration) in adults with Advanced Systemic Mastocytosis. The investigational drug is known as CGT9486 and will be taken daily orally. Participation in the study is expected to be approximately 6 years.

The objective of this research study is to identify brain biomarkers using MRI scans that can predict an individual's response to Deep Brain Stimulation (DBS). A total of 55 participants with Parkinson's Disease planning to undergo DBS will be recruited from MUSC's Clinical DBS Program. Participants will undergo two visits which include a 2.5-hour pre-DBS questionnaire and MRI scanning visit, and a 3.5-hour post-DBS cognitive assessment visit. In addition control participants without Parkinson's Disease will be recruited to undergo MRI scanning and cognitive assessments.

The study will be an open-label, randomized, parallel arm study that will include a
treatment arm and control arm. Participants will have clinic visits at screening, randomization (day 1) and weeks 4, 12, 18, and 24. After week 24, participants will have clinic visits at weeks 32, 40, and 48. Participants will also have a telehealth visit on day 2 and phone calls to assess adverse events (AEs), serious adverse events (SAEs), and review patient education will occur during weeks 5, 8, 36, and 44. The phone calls may be converted to telehealth visits or clinic visits and / or followed by clinic visits, if the study team deems it necessary. Pulmonary function testing, quality of life survey (St. George's Respiratory Questionnaire (SGRQ)), and blood draw will occur at each clinic visit.

The purpose of this research study is to determine if an already FDA approved drug called atorvastatin can help adults, age 75 or older, live well for longer by preventing dementia, disability, or heart disease. Participants will be assigned by chance to receive either atorvastatin (study drug) or a matching placebo (a tablet that looks like atorvastatin but does not contain any medicine). Study engagement may last up to five years and involves in clinic and/or remote visits, survey questions, potential blood draws, in addition to memory and physical tests. After the first 1-2 visits performed in clinic or remote, the study team will follow-up via phone on a yearly basis to see how participants are doing. Participants will be compensated for their time and participation in this research study.
