Active clinical trials for "Anemia, Sickle Cell"

The purpose of this study is to determine if warming the intravenous (IV) fluid given to patients with Sickle Cell Disease who are experiencing painful episodes known as Vaso-Occlusive Episodes; will decrease rates of hospital admission, decrease amounts of IV pain medications given, improve pain and improve global comfort.

This protocol will be investigating the use of stem cell transplantation, in related donors, to cure sickle cell disease. Sickle cell disease is a recessive disorder caused by a point mutation that results in the substitution of valine for glutamic acid at the sixth position in the B-chain of hemoglobin. This leads to sickling of the red blood cells under many conditions, such as hypoxia, dehydration, and hyperthermia. The sickling leads to vaso-occlusion, which causes irreversible damage in almost all systems in the body, including the central nervous system (CNS), lungs, heart, bones, eyes, liver, and kidneys.

The purpose of this study is to compare the safety of SANGUINATE™ versus Hydroxyurea in patients suffering from Sickle Cell Disease.

This is a phase I/II study of patients with sickle cell disease. It aims to find out if people with sickle cell disease can be cured by changing their immune system before they have blood stem cell transplants. Doctors will give patients a new drug (fludarabine) to see if this drug changes patients immune system and reduces the patient's cells (host) from rejecting donor cells (graft) after the patient gets a Hematopoietic (blood) stem cell transplant.

The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) administered for 12 or 24 weeks in adults with genotype 1 or 4 hepatitis C virus (HCV) infection with sickle cell disease (SCD).

The purpose of this study is to evaluate the performance of the AMICUS Red Blood Cell Exchange (RBCx) System (Exchange and Depletion/Exchange procedures) in patients with sickle cell disease.

The purpose of this study is to determine whether Gum Arabic is effective as fetal hemoglobin inducing agent for sickle cell anemia patients.

Background: - Sickle cell disease (SCD) is a blood disease. The drug hydroxyurea (HU) is approved to prevent pain crises in people with SCD. Researchers want to see how higher doses of HU affect the blood. This will help them learn about the right dosage of HU to give to people with SCD. Objective: - To improve hydroxyurea dosing in people with SCD. Eligibility: - People age 15 or older with homozygous SCD (HbSS). Design: Participants will be screened with medical history, physical exam, medication review, and blood and urine tests. Participants will be in the study for about 15 months. First 3 months: monthly study visits with blood and urine tests. After 3 months: participants will take HU as a capsule by mouth. If you are already taking HU, your dose will be increased. Within a month of starting or increasing HU: participants will keep a daily pain diary for 2 weeks. They will have an echocardiogram (ultrasound) of the heart, a 6-minute walk test. They will complete a quality-of-life questionnaire. Participants will visit every month until they reach their highest tolerated dose of HU. They may need to come as often as every week sometimes to closely monitor their blood counts. Then they will alternate a phone call one month and a visit the next. At the visits, participants will bring their pill bottle, answer questions about side effects, and have blood tests. Every 2 months, participants will have a medical history, physical exam, and blood tests. Every 4 months, participants will have blood and urine tests. They will also complete another 2-week pain diary and quality-of-life questionnaire. About 12 months after starting or increasing HU, participants will have blood tests, an echocardiogram, and a 6-minute walk test.

Symptomatic sickle cell disease is worldwide the most frequent cause for hereditary hemolytic anemia with recurrent pain crisis. Hemolysis, vaso- occlusive and pain crises are hallmarks of this disease and are causative for an important socio-economic burden worldwide, especially in Africa. Aside from allogenic stem cell transplantation, which is rarely available and very expensive, at present there is no curative treatment for patients with sickle cell disease (SCD). The current standard of care includes treatment with hydroxycarbamide and symptomatic care such as transfusions, antibiotic/analgesic treatment. This study has the aim to study the safety and tolerability of Memantin in patients with sickle cell disease.

The purpose of this study is to assess the safety, tolerability, pharmacokinetic, and pharmacodynamic effects of GBT440 compared with placebo in healthy subjects and subjects with sickle cell disease (SCD).
