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 Nonadvanced Systemic Mastocytosis. The investigational drug is known as bezuclastinib and will be taken daily orally. Participation in the study is expected to be approximately 3 years.

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.

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 purpose of this study is to compare the safety and efficacy of the PMX cartridge ( Toramyxin) (in Addition to Standard Medical Care for Patients with Endotoxemic Septic Shock:
Eligible and consented subjects will be randomized to receive either the PMX cartridge (administered twice for 1½ to 2 hours per treatment session approximately 24 hours apart) plus standard medical care or standard medical care alone. For all subjects in whom treatment has been initiated, a follow-up visit (if they are still in the hospital) or a telephone call will be completed at Day 28 (or later) to determine their mortality status. In surviving subjects, a follow-up visit or telephone call to determine their mortality status will also take place at approximately three months (i.e. Day 90) and 12 months after the subject was randomized.

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 registry is an observational study designed to evaluate the effect of Oxbryta in individuals with Sickle Cell Disease (SCD) in a real-world setting.

Participants who are currently taking or have been prescribed and initiating standard of care treatment with Oxbryta are eligible to participate. This registry will collect data that is recorded in participants' medical records and other off site sources. Study data will be collected a regular intervals and entered in case reports (CRFs) by electronic capture system (EDC) by the study staff. Participants will be on the study for 5 years after their first dose of Oxbryta treatment or until they choose to withdraw from the study. Participants who stop Oxbryta treatment prior to the 5 years will continue to be monitored at regular intervals unless they request to withdraw from study. Participants quality of life (QoL) questionnaires will be collected throughout the 5 years of the study.

Participants safety and tolerability will be assessed throughout the study data collection period by the study doctor and reported to the Sponsor.

The purpose of this study is to see if taking depemokimab is safe and effective in treating Hypereosinophilic syndrome (HES) in adults (≥18 years) with uncontrolled HES receiving standard of care (SoC) therapy. The study will last approximately 52 weeks and is a placebo-controlled, double blind, multicentre study.

Vaso-occulsive crisis is a complication of Sickle cell disease in which the red blood cells (RBC) change shape, causing congestion within the blood vessels that leads to pain and tissue damage.

The study medication FT-4202, an oral tablet, is believed to reduce the rate of sickle cell polymerization and improve RBC membrane function, thereby reduction sickling of RBCs and their hemolysis (breakdown of red cells) that causes vascular obstruction and anemia.

This study will consist of a 52-week, randomized (volunteers are selected by chance to receive study either study medication or placebo) , placebo controlled (a placebo is a look-alike pill that contains no active medication). There will be 17 study visits.

The study is followed by a 52-week open label extension study in which all participants will receive study medication. There will be 11 study visits.

Iron deficiency is the most common type of nutritional deficiency in the world and is unique in that it affects both developing and developed countries. The most common complication of iron deficiency is anemia (a low level of iron in the red blood cells). Although patients with anemia may not have any symptoms, many patients with anemia do have problems such as fatigue, tiredness, shortness of breath and/or pale skin.

Study participants will undergo some evaluations in addition to their regular anemia work up. These include the following:
1) Questionnaires;
2)Iron absorption test consisting of 3 blood samples over the span of 3 hours after having drank a liquid iron solution.
3) stool and urine sample collection.
4) food diary to monitor iron dietary intake.
5)If an upper endoscopy is also part of the participant's standard of care workup, the study team will ask the endoscopist to take an additional biopsy sample to test for one of the proteins that is responsible for taking up iron from your food into the intestine.

Participation in this study will last over 2 visits lasting 1 to 4 hours each. The two visits should fall within the span of 1 month of each other.

Risks associated with this study include side effects of oral iron supplement ingestion. This oral iron may have a metallic taste. In some patients, it could even cause nausea or vomit, abdominal gas or abdominal discomfort. We also ask to draw blood and blood withdrawal may have side effects including bruising, pain, bleeding or rarely infection at the puncture site. Confidentiality breach is also a risk.

There are no direct benefits to the participant. However, this study will help advance diagnosis and clinical assessments of iron deficiency anemia.

The alternative is to not participate in the study and continue regular iron deficiency anemia work up exclusively with the treating physician and medical team.

Alzheimer's disease and Epilepsy may affect over 80% of individuals that have Down syndrome by the age of 60. Biomarkers found in the blood can enhance our understanding of the earliest changes linked to disease and may enhance clinical detection and healthy aging for individuals with Down syndrome.

The purpose of this study is to discover early neurobiological processes underlying the transition from healthy aging to disease. Our research team has developed technology that allows detection of small changes in the brain that get transferred to the blood.

We are recruiting individuals that either have or do not have Down syndrome for this biomarker study. Participants should be between the ages of 6 months and 85 years old and may include mothers and siblings of a child with Down syndrome. Infants and children will require consent form a parental or legal guardian.

Each participant will provide a blood sample for research purposes. We will also gather some basic health information about senses, habits, exercise level and smoking/vaping exposures.
