Active clinical trials for "Anemia, Sickle Cell"

The purpose of this Phase 1a, first in human, randomized, double-blind, placebo-controlled study is to evaluate the safety, tolerability, PK and PD profile of the orally administered IMR-687 in healthy adult subjects.

Disease-related neurocognitive deficits are common in pediatric sickle cell disease (SCD). These deficits can significantly disrupt otherwise normal trajectories toward academic and vocational achievement and negatively impact psychosocial outcomes. Despite widespread recognition of neurocognitive deficits, there are no treatments shown to maintain or recover functioning once a child with SCD endures neuronal damage. Cognitive training (CT) has been a standard intervention used to stabilize and recover functioning in individuals with accidental or disease-related brain injury. Recent advances in technology have led to the development of computerized CT programs. This study seeks to assess the feasibility and efficacy of using computerized CT with pediatric patients with SCD. Children and adolescents with SCD between the ages of 7 and 16 years old (n = 80) will be recruited to complete a randomized (intervention or waitlist-control) home-based computerized CT program (Cogmed). Feasibility will be assessed by examining participation, retention, and program completion rates, as well as feedback from a feasibility and acceptability questionnaire and a brief qualitative interview. Participants will also complete assessments of attention, working memory, and academic fluency at baseline and immediately following the intervention. A final assessment will be conducted 6 months after the conclusion of the intervention to evaluate the stability of treatment effects.

The aim of this study is to determine whether giving extra arginine, a simple amino acid, to patients with sickle cell disease seeking treatment for a pain crisis (vaso-occlusive painful events (VOE) will decrease pain scores, decrease the need for pain medications or decrease length of hospital stay or emergency department visit.

SANGUINATE™ Sickle Cell Disease associated Leg Ulcers.

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 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.

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.

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.

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.
