Sickle Cell Disease Clinical Trials

This phase I trial tests the safety and effectiveness of total marrow and lymphoid irradiation (TMLI) and alemtuzumab as a conditioning regimen in patients with sickle cell disease. Conditioning regimens are treatments used to prepare a patient for stem cell transplantation. A stem cell transplant is a procedure in which a person receives blood stem cells, which make any type of blood cell. A conditioning regimen may include chemotherapy, monoclonal antibody therapy, and radiation to the entire body. It helps make room in the patient's bone marrow for new blood stem cells to grow, and helps prevent the patient's body from rejecting the transplanted cells. Alemtuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Graft-versus-host disease (GVHD) is a complication that may occur after hematopoietic cell transplantation (HCT) in which donated cells view the recipient's cells as foreign and attack them. Giving TMLI and alemtuzumab may help reduce organ damage that can be caused by radiation and decrease the risk of GVHD. Read Less

This is a single-arm, mechanistic clinical trial to measure predictors of senescence and the in vivo survival of transfused red blood cells (RBCs) in individuals with sickle cell disease (SCD) receiving chronic transfusion therapy (CTT). Chronic transfusion in patients with SCD is a common treatment. The efficacy of RBC transfusion therapy to treat or prevent complications of SCD may be hampered by variable survival of the transfused donor RBC. The overall aim is to see how long RBC survive in SCD patients who are chronically transfused. When a study participant has a regular blood transfusion the researchers will label a small portion of the RBCs that are transfused with biotin. The participant will return at Day 1, weekly for 3 months and monthly for 3 months to measure how long those RBCs survive. An optional sub-study using INTERCEPT RBCs will mirror the main study but will use INTERCEPT RBCs that have biotinylated for 1 RBC unit. Read Less

This multisite prospective study seeks to determine if HLA-identical sibling donor transplantation using alemtuzumab, low dose total-body irradiation, and sirolimus (Sickle transplant Using a Nonmyeloablative approach, "SUN") can decrease the toxicity of transplant while achieving a high cure rate for children with sickle cell disease (SCD).

The SCD-CARRE trial is a Phase 3, prospective, randomized, multicenter, controlled, parallel two-arm study aimed to determine if automated exchange blood transfusion and standard of care administered to high mortality risk adult SCD patients reduces the total number of episodes of clinical worsening of SCD requiring acute health care encounters (non-elective infusion center/ER/hospital visits) or resulting in death over 12 months as compared with standard of care.

This study is being done to see if the study drug, motixafortide, is safe in participants with sickle cell disease (SCD). Investigators also want to see if the drug will help the body increase the number of stem cells that can be collected for possible future transplant use. PRIMARY OBJECTIVE * To characterize the safety and tolerability of motixafortide in participants with SCD as determined by the incidence of adverse events (AEs). SECONDARY OBJECTIVES * To characterize the efficacy of a single dose (Part A) or two doses (Part B) of motixafortide for hematopoietic stem cell (HSC) mobilization and apheresis collection in participants with SCD as determined by the yield of CD34+ cells (CD34+ cells/kg). * To measure the mobilization effects of single-day (Part A) or daily dosing (Part B) dosing with motixafortide in the peripheral blood in participants with SCD as determined by peak peripheral blood CD34+ counts * To recommend a phase 2 dosing strategy based on safety, efficacy, and mobilization effects Read Less

This clinical trial is a Phase 2 study that will evaluate the safety and clinical activity of etavopivat in patients with thalassemia or sickle cell disease and test how well etavopivat works to lower the number of red blood cell transfusions required and increase hemoglobin. Read Less

This study is a cooperative investigation funded by the NIH. The project is a collaboration among three major NIH Clinical Translational Science Awardees: 1) UCI (lead site with its affiliate CHOC), 2) Northwestern University (with its affiliate Lurie Children's Hospital), and 3) USC (with its affiliate Children's Hospital of Los Angeles). There is an increasing number of children who, through medical advances, now survive diseases and conditions that were once fatal, but which remain chronic and debilitating. A major challenge to improve both the immediate and long term care and health of such children has been the gap in our understanding of how to assess the biological effects of exercise. Like otherwise healthy children, children with chronic diseases and disabilities want to be physically active. The challenge is to determine what constitutes safe and beneficial level of physical activity when the underlying disease or condition \[e.g., cystic fibrosis (CF) or sickle cell disease (SCD)\] imposes physiological constraints on exercise that are not present in otherwise healthy children. Current exercise testing protocols were based on studies of athletes and high performing healthy individuals and were designed to test limits of performance at very high-intensity, unphysiological, maximal effort. These approaches are not optimal for children and adolescents with disease and disability. This project (REACH-Revamping Exercise Assessment in Child Health) is designed to address this gap. Cohorts of children will be identified with two major genetic diseases (CF and SCD) and measure exercise responses annually as they progress from early puberty to mid or late puberty over a 3-4year period. In addition, in the light of the pandemic, a group of children will be added who were affected by SARS-CoV-2 and investigate their responses to exercise. SARS-CoV-2 has similar long-term symptoms than CF and SCD have. Novel approaches to assessing physiological responses to exercise using advanced data analytics will be examined in relation to metrics of habitual physical activity, circulating biomarkers of inflammation and growth, leukocyte gene expression, and the impact of the underlying CF, SCD or SARS-CoV-2 condition. The data from this study will help to develop a toolkit of innovative metrics for exercise testing that will be made available to the research and clinical community. Read Less

The Sickle Cell Children's Exercise Study (SuCCESs) will explore the feasibility and effects of a moderate intensity strengthening, balance, speed, and agility intervention program in children with sickle cell disease. Read Less

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. Read Less

This study will evaluate the acceptability, feasibility, and preliminary efficacy of a shared decision making intervention for adolescents and young adults (AYAs) with sickle cell disease (SCD). 60 AYAs with SCD ages 15-25 and their caregivers and 8 SCD providers will participate in the pilot pragmatic trial. AYAs, caregivers, and providers will be recruited from Nemours Children's Hospital, Delaware (NCH-DE), Nemours Children's Hospital in Orlando, FL (NCH-ORL), and Nemours Children's Health at Wolfson Children's Hospital in Jacksonville, FL (NCH-JAX). NCH-DE participants (n=30) will receive the SDM intervention including a virtual reality patient health education component, whereas NCH-ORL and NCH-JAX participants (n=30) will receive the SDM intervention with standard patient education materials (print, video). SCD providers will be trained to use the toolkit components and will introduce decision aids during an outpatient clinic visit for AYAs who are candidates for one or more disease-modifying therapies.
