The purpose of this study is to find the smallest amount of the 131 I-apamistamab needed for preparing patients with severe sickle cell disease (SCD) for a bone marrow transplant. This is the first time 131 I-apamistamab is being used for advanced Sickle Cell Disease (SCD) in the setting of allogeneic stem cell transplant. 131 I-apamistamab is an investigational product. This means that 131 I-apamistamab has not been approved by the Food and Drug Administration (FDA) for medical use in patients. The study treatment that is given before the transplant is called the conditioning regimen. In this study, the investigators are adding a drug called 131 I-apamistamab instead of the conditioning regimen typically given before a stem cell transplant.
Feasibility and reliability of ultrasound in the inpatient hematology setting.
The purpose of this study is to evaluate the safety and tolerability, pharmacokinetics and pharmacodynamics, pH and food effect, and preliminary efficacy of BMS-986470 in healthy volunteers and participants with sickle cell disease.
A phase III, multi-center, randomized, placebo-controlled, double-blind study to assess efficacy and safety of crizanlizumab (5 mg/kg) versus placebo, with or without hydroxyurea/hydroxycarbamide therapy, in adolescent and adult Sickle Cell Disease patients with frequent vaso-occlusive crises.
The purpose of this study is to find out whether siplizumab is safe and effective for patients with SCD undergoing an allogeneic transplant and to prevent development of Graft versus Host Disease (GVHD) and graft failure. The main goals of this study are : * To determine if acute GVHD occurs and how severe the acute GVHD is in subjects receiving the study drug * To determine if graft failure occurs in subjects receiving the study drugs In this study, participants will receive 5 infusions of the study drug, siplizumab, while getting a stem cell transplant for SCD. Before siplizumab infusion, participants will be given medications to reduce the risks of allergic reaction to the drug.
Background: Sickle cell disease (SCD) is a genetic disease that causes the body to produce abnormal ( sickled ) red blood cells. SCD can cause anemia and life-threatening complications in the lungs, heart, kidney, and nerves. People with SCD are also at increased risk of forming blood clots in the veins and lungs, but the standard treatments for these clots can cause increased bleeding in people with SCD. Better treatments are needed. Objective: To test a drug (fostamatinib) in people with SCD. Eligibility: People aged 18 to 65 with SCD. Design: Participants will have 6 clinic visits over 12 weeks. Each visit will be 2 to 3 hours. Participants will be screened. They will have a physical exam with blood tests. They will tell the researchers about the medications they take. Fostamatinib is a tablet taken by mouth. Participants will take the drug at home, twice a day, for up to 6 weeks. Participants will have a clinic visit every 2 weeks while they are taking the drug. At each visit they will have a physical exam with blood tests. They will talk about any side effects the drug may be causing. If they are tolerating the drug well after the first 2 weeks, they may begin taking a higher dose. Participants will have a final visit 4 weeks after they stop taking the drug. They will have a physical exam and blood tests; they will be checked for any side effects of the drug.
This will be a first time in human (FTIH) study in sickle cell diseases (SCD) participants. The FTIH study is planned to evaluate the safety, tolerability, and pharmacokinetics of GSK4172239D. The study will be composed of 3 periods for all participants (Screening, Treatment, and Follow up). Participants will be screened and, prior to first dose on Day 1, will be randomized to receive either GSK4172239D or placebo. GSK4172239D is a prodrug that is converted in vivo into GSK4106401. This study will be a single dose, dose-escalation study. The initial dosing for all cohorts will be staggered so that 2 participants will be dosed as sentinel participants. Provided there are no safety concerns in 48 hours (h), the remaining 6 participants scheduled for the cohort may be dosed. One selected cohort of participants will also receive an additional single dose of GSK4172239D (or matching placebo) under fed (high calorie and high fat) conditions after a washout period of a minimum of 20 days or 5 half-lives, whichever is longer, designated as the Food Effect Cohort.
This is a single-dose, open-label study in participants with transfusion-dependent β-thalassemia (TDT) or severe sickle cell disease (SCD). The study will evaluate the safety and efficacy of autologous CRISPR-Cas9 modified CD34+ human hematopoietic stem and progenitor cells (hHSPCs) using CTX001.
Research Type: Clinical Trial Background: People with sickle cell disease (SCD) have many health challenges. Also, they often have trouble sleeping. Acceptance and commitment therapy (ACT) might help people with SCD to improve their sleep problems. Objective: To see how well ACT works in people with SCD and sleep problems and to find out how they feel about it. Eligibility: People between the ages of 18 and 55 with SCD and trouble sleeping. Design: The study is remote. Participants will not have to come to the NIH at all. They will need a device that has Bluetooth and can connect to the internet. Some participants will be in the study for 12 weeks. Others will participate for 20 weeks. Participants will video chat with an ACT coach once a week for 8 weeks. The coach will guide participants through mindfulness exercises and teach ACT ideas. Each session lasts about 45 minutes. Participants will be loaned an actigraph, a device worn on the wrist like a watch that measures and records movement. They will download a free app to upload data from the actigraph for the researchers. Participants will wear the actigraph on their nondominant wrist day and night for either 4 or 6 designated weeks. During these weeks, participants will complete a sleep diary each morning when they wake up. This takes about 2 minutes. Participants will be sent other surveys to complete from home during the study. They will answer questions about their physical and emotional health. These take 20-25 minutes. The last survey will be 4 weeks after participants finish the ACT treatment. They will answer questions about how helpful they thought ACT was and how easy or hard it was to wear the actigraph.
This is a multicenter prospective, longitudinal cohort study which will evaluate the predictive capacity of machine learning (ML) models for progression of CKD in eligible patients for a minimum of 12 months and potentially for up to 4 years.
