The purpose of the study is to assess the safety and tolerability of AG-946 in healthy volunteers after oral administration of single ascending doses (SAD) and multiple ascending doses (MAD) of AG-946 over 14 or up to 28 days of dosing, and to identify a range of doses that are safe and pharmacologically active in participants with sickle cell disease. The SAD and MAD parts of the study will be randomized and double-blinded, and will assess the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of AG-946 as well as the effect of food (SAD only) on the pharmacokinetics (PK) of AG-946. The sickle cell disease (SCD) part of the study will be non-randomized and open-label, and is designed to identify 1 or more safe and tolerable dose(s) of AG-946 with potential activity in the treatment of participants with sickle cell disease (SCD).
Background: Sickle cell disease (SCD) is an inherited hemoglobin disorder. People with SCD have an increased chance for getting blood clots. Researchers want to see if a dietary supplement called isoquercetin can decrease levels of inflammation and blood clotting in people with SCD. Objective: To see how isoquercetin works in people with SCD. Eligibility: Adults age 18-70 years old who have SCD and are in a steady-state (have not experienced a pain crisis in the last 60 days and, if taking hydroxyurea, have not had a dose change in the past 90 days). Design: Participants will be screened with a physical exam, medical history, medicine review, and blood tests. Participants will be put in 1 of 2 treatment groups. They will take 4 capsules of isoquercetin or placebo all at once, by mouth, every day for 4 weeks. They will get a pill dispenser and keep a medicine diary. Participants may have an optional near infrared spectroscopy (NIRS) test to measure how treatment affects blood flow. In this test, probes will be placed on the skin to measure tissue oxygen level and blood flow. A blood pressure cuff placed on the arm will be filled with air briefly to restrict the blood flow in the arm (for up to 5 minutes) and then released. Participants may also be asked to breathe at a certain rate or hold their breath for as long as they can during measurements. Participants will take folic acid once a day. Participants will have an end-of-study drug visit. They will discuss any side effects and repeat some of the screening tests. They may have an additional optional NIRS test. About a month after the end of study drug visit, participants will be contacted by phone to see if they have any side effects. Those who do may have a follow-up visit. At this visit, they may have additional blood tests performed. Participation will last from 8 to 12 weeks.
This pilot research is aimed to assess the needs of patients and health workers involved in Sickle Cell Disease (SCD) management in Nigeria. To achieve this, a questionnaire will be administered to SCD patients or parents of children affected by SCD. Another questionnaire will be administered to doctors and nurses working with SCD patients. A focus group discussion with patients/parents willing to participate will be also scheduled. Participants from the following centres will be involved: Barau Dikko Teaching Hospital Kaduna State University, Ahmadu Bello University Teaching Hospital Zaria, National Hospital Abuja, Federal Medical Centre Katsina. Data will be qualitatively and quantitatively analysed and presented as aggregated data. Consent from all the study participants will be sought. Questionnaires will be coded and no personal data will be disclosed to authorised third parties.
Background: Sickle cell disease (SCD) is an inherited blood disorder. It results from a single genetic change (mutation) in red blood cells (RBCs). RBCs are the cells that carry oxygen to the body. In people with SCD, some RBCs are abnormal and die early. This leaves a shortage of healthy RBCs. Researchers want to learn more about how long RBCs live in the human body. Objective: To study how long RBCs live in people with and without SCD. Eligibility: People age 18 and older who either have SCD, had SCD but were cured with a bone marrow transplant, have the sickle cell trait (SCT), or are a healthy volunteer without SCD or SCT Design: Participants will be screened with a medical history and physical exam. They will give a blood sample. Participants will have a small amount of blood drawn from a vein. In the laboratory, the blood will be mixed with a vitamin called biotin. Biotin sticks to the outside of RBCs without changing their function, shape, or overall lifetime. This process is known as biotin labeling of RBCs. The biotin labeled RBCs will be returned to the participant via vein injection. Participants will give frequent blood samples. Their RBCs will be studied to see how many biotin labeled RBCs remain over time. This shows how long the RBCs live. Participants will give blood samples until no biotin labeled RBCs can be detected. During the study visits, participants will report any major changes to their health. Participation lasts for up to 6 months.
Background: Sickle cell disease (SCD) is a chronic illness. It affects about 100,000 people in the United States. People with SCD have red blood cells that are sickle-shaped and impaired in their function. This results in a lifetime of complications that affect every organ system. People with SCD also are at greater risk for respiratory infections and lung problems. Researchers want to study how this population s stress, anxiety, fear, pain, sleep, and health care use are being affected by the COVID-19 pandemic. Objective: To study the extent and impact of life changes induced by the COVID-19 pandemic on people living with SCD in the U.S. Eligibility: People age 18 and older with SCD who live in the U.S. Design: Participants will complete a survey online. The questions will focus on the following: Medical history Mental and physical health Demographics Stress Resilience Health care use COVID-19 Beliefs about medical mistrust and participation in research. At the end of the survey, participants will be asked if they would like to take the survey again in the future. If they reply "yes," then they will be contacted by the study team in 6-9 months to take the survey again. They may complete the survey again in 6-8 months, 12-15 months, and 18-21 months. The survey should take less than 40 minutes to complete. Participants' data will be coded to protect their privacy. The coded data may be shared with other researchers.
Sickle cell disease (SCD) is the most common genetic disease in France. Its consequences on patient's life-course and quality of life need to be precisely identified among French patients and their family to be able to improve patients care according to their specific needs. The aim of the study is to accurately describe the impact of SCD on quality of life of patients living in France, or their family (for minor patients). The consequences of the disease on professional life, education and material condition of patients or their parents will be described by the patients themselves.
This is a study to evaluate the effect of voxelotor on daily physical activity and sleep quality, as measured by a wrist-worn device in participants with sickle cell disease (SCD) and chronic moderate anemia.
Pain is the primary complication of sickle cell disease (SCD), including vaso-occlusive crises and more persistent, chronic pain. SCD-related pain is associated with significant functional impairment, spanning poor school attendance, decreased quality of life, and stress and mood difficulties. Pharmacological approaches are the first-line treatment for SCD-related pain, but these can be costly and have unwanted side effects. Given limitations from pharmacological approaches and the influence that poor behavioral responses have on disease management and health outcomes suggest a critical need for alternative and adjunctive treatments. Due to gaps in available behavioral treatments specifically designed for addressing common challenges associated with pain management in pediatric SCD, the investigators developed a manualized behavioral therapy protocol by tailoring existing evidence-based treatments. The overall goal of the intervention is to reduce the impact of pain on daily functioning in pediatric SCD. This study will empirically test the feasibility and preliminary efficacy of this intervention for youth with SCD. Children and adolescents with SCD between the ages of 8 and 17 years old (n=20) will be recruited to complete the treatment protocol. Feasibility will be assessed by examining participation and program completion rates, as well as feedback from a treatment acceptability questionnaire and qualitative interview. Participants will complete baseline assessments, weekly questionnaires, and post-treatment assessments (post-intervention assessment, follow-up time points: 1-month following the intervention, and 3-months following the intervention).
The aim of the present study is comparing the effectiveness of different treatment regimens for investigating the therapeutic potential for each one in management of Vaso-occlusive pain in pediatric sickle cell disease. In addition, investigators apply the Cost-effectiveness analysis (CEA) as a form of economic analysis that compares the relative costs and outcomes (effects) for different treatment regimens on vaso-occlusive painful crisis.
