Active clinical trials for "Anemia, Sickle Cell"

The purpose of this study is to evaluate the efficacy, safety and tolerability of treatment with EDIT-301 in adult participants with severe sickle cell disease (SCD).

This study aims to enroll 58 pre-adolescent (<13 years) pediatric participants with sickle cell disease (SCD) who have a pre-adolescent sibling bone marrow donor. All participants will go through a pre-transplant evaluation to find out if there are health problems that will keep them from being able to receive the transplant. It usually takes 2 to 3 months to complete the pre-transplant evaluation and make the arrangements for the transplant. Once they are found to be eligible for transplant, participants will be admitted to the hospital and will start transplant conditioning. Conditioning is the chemotherapy and other medicines given to prepare them to receive donor cells. It prevents the immune system from rejecting donor cells. Conditioning will start 21 days before transplant. Once they complete conditioning, participants will receive the bone marrow transplant. After the transplant, participants will stay in the hospital for 4-6 weeks. After they leave the hospital, participants will be followed closely in the clinic. Outpatient treatment and frequent clinic visits usually last 6 to 12 months. Routine medical care includes at least a yearly examination for many years after transplant by doctors and nurses familiar with sickle cell disease and transplant. The researchers will collect and study information about participants for 5 years after transplant.

Background: Sickle cell disease (SCD) is an inherited disorder of the blood. It can damage a person s organs and cause serious illness and death. A blood stem cell transplant is the only potential cure for SCD. Treatments that improve survival rates are needed. Objective: To find out if a new antibody drug (briquilimab, JSP191) improves the success of a blood stem cell transplant Eligibility: People aged 13 or older who are eligible for a blood stem cell transplant to treat SCD. Healthy family members over age 13 who are matched to transplant recipients are also needed to donate blood. Design: Participants receiving transplants will undergo screening. They will have blood drawn. They will have tests of their breathing and heart function. They may have chest x-rays. A sample of marrow will be collected from a pelvic bone. Participants will remain in the hospital about 30 days for the transplant and recovery. They will have a large intravenous line inserted into the upper arm or chest. The line will remain in place for the entire transplant and recovery period. The line will be used to draw blood as needed. It will also be used to administer the transplant stem cells as well as various drugs and blood transfusions. Participants will also receive some drugs by mouth. Participants must remain within 1 hour of the NIH for 3 months after transplant. During that time, they will visit the clinic up to 2 times a week. Follow-up visits will include tests to evaluate participants mental functions. They will have MRI scans of their brain and heart.

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.

Vaso-occlusive crisis are highly painful in Sickle-cell patients. Morphine is the treatment of choice for this pain. Various adjuncts have been studied for the treatment of vaso-occlusive crisis. The investigators aimed to study the effect of clonidine associated with morphine in PCIA (patient controlled intravenous analgesia pumps) regimen. The investigators will compare it to the morphine alone in PCIA for the treatment of vaso-occlusive pain. The investigators will measure the morphine consumption of all patient, the impact on the apparition of the morphine secondary effect and on inflammation biomarkers and the biopsychosocial respond. Each patient will be hospitalized and follow by haematologist from the hospital, pain doctors and nurses. It will be a double blind randomised, prospective study. The randomisation will be done by the pharmacy.

This is a follow-up trial to NYMC 526 (NCT01461837) to assess the safety, efficacy and toxicity of administering Defibrotide prophylaxis for high-risk sickle cell or beta thalassemia patients undergoing a familial haploidentical allogeneic stem cell transplantation with CD34 enrichment and T-cell addback. This patient population historically has a risk of developing sinusoidal obstructive syndrome (SOS) and Defibrotide has demonstrated efficacy in treatment of SOS. The Funding Source is FDA OOPD.

This Phase I clinical trial will assess the safety and initial evidence for efficacy of an autologous transplant of lentiviral vector modified peripheral blood for adults with severe sickle cell disease.

People with severe congenital anemias, such as sickle cell anemia and beta-thalassemia, have been cured with bone marrow transplantation (BMT). The procedure, however, is limited to children younger than the age of 16 because the risks are lower for children than for adults. The purpose of this study is to explore the use of a BMT regimen that, instead of chemotherapy, uses a low dose of radiation, combined with two immunosuppressive drugs. This type BMT procedure is described as nonmyeloablative, meaning that it does not destroy the patient s bone marrow. It is hoped that this type of BMT will be safe for patients normally excluded from the procedure because of their age and other reasons. To participate in this study, patients must be between the ages of 18 and 65 and have a sibling who is a well-matched stem-cell donor. Beyond the standard BMT protocol, study participants will undergo additional procedures. The donor will receive G-CSF by injection for five days; then his or her stem cells will be collected and frozen one month prior to BMT. Approximately one month later, the patient will be given two immune-suppressing drugs, Campath 1-H and Sirolimus, as well as a single low dose of total body irradiation and then the cells from the donor will be infused. Prior to their participation in this study, patients will undergo the following evaluations: a physical exam, blood work, breathing tests, heart-function tests, chest and sinus x-rays, and bone-marrow sampling. ...

The investigators are evaluating the role of a low dose of tocilizumab in treating acute chest syndrome in patients with sickle cell disease. Tocilizumab inhibits interleukin-6 (IL-6) receptors and is used to treat rheumatoid arthritis and severe cytokine release syndrome, which can be seen with chimeric antigen receptor T-cell (CAR-T) therapy, and it is also authorized for treatment of COVID-19. Since IL-6 levels are elevated in the sputum of patients with acute chest syndrome, the investigators are hopeful that this will be an effective strategy. The investigators will be looking at how a low dose of tocilizumab affects oxygen status, clinical outcomes, and laboratory markers in patients admitted to the hospital with acute chest syndrome.

This study is a Phase 3, multicenter, randomized, placebo-controlled study to evaluate the efficacy of voxelotor and standard of care for the treatment of leg ulcers in participants with sickle cell disease. The study is divided into a 5 study periods: Screening, Run-in, Randomized Treatment, Open-label Treatment, and Follow-up/End of Study (EOS). The study will be conducted in approximately 80 eligible participants at approximately 20 global clinical trial sites.
