Active clinical trials for "Anemia, Sickle Cell"

Patients who have sickle cell VOC are usually treated with opioids, such as morphine. However, this current way of treating them has not improved the health, medical outcomes, or rates of hospitalizations. In addition, since VOC can happen very frequently over a long period of time, giving opioids over and over again can cause both short-term and long-term problems. Nitrous oxide (N2O) is a way of treating pain that may provide a better alternative to repeatedly giving opioids over long periods of time. N2O has been shown to provide up to 3 hours of pain relief in inpatient patients with VOC whose pain did not improve with morphine infusions, and is used extensively in France, where almost half of 85 pediatric emergency departments use nitrous oxide to treat children with VOC whose pain did not get better with standard treatment with morphine. However, pain relief which N2O provides in the acute setting has not been well described. Therefore, the purpose of our study is to describe how well N2O can relieve the pain in patients with SCD who present to the emergency department and are experiencing a VOC.

Related donor stem cell transplantation using the alemtuzumab/ TBI platform has been shown to be a safe strategy to cure severe sickle cell disease. However, due to a lack of suitable donors, many patients cannot benefit from this strategy. Alternative donor sources are desperately needed to fill this gap. Nearly all patients will have a haploidentical family member who would be able to donate. The use of post transplantation cyclophosphamide has greatly improved the outcome of haploidentical stem cell transplantation. The investigators propose to combine this with alemtuzumab/TBI conditioning.

The major goal of this study is to determine the risks and benefits of stem cell transplants in combination with a newer, less toxic conditioning chemotherapy treatment in patients with severe sickle cell disease (SCD) or sickle hemoglobin variants (hemoglobin SC or hemoglobin SB0/+), or homozygous b0/+ thalassemia or severe B0/+ thalassemia variants. Participation in this project will be for one year, with follow up evaluations done every 6 months thereafter for 10 years or until participants are 18 years old.

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.

Voxelotor is a novel hemoglobin polymerization inhibitor which has been demonstrated to reduce hemolysis and improve hemoglobin levels. There have been numerous studies examining the clinical impact of voxelotor in sickle cell disease (SCD) patients, but there are few published reports on the effects of treatment on physical function in patients with SCD. The hypothesis to be tested is that anemic SCD patients will have improvements in performance after 6 months of voxelotor treatment.

The proposed study is a Phase 2 multi-center, randomized, double-blind, placebo-controlled, parallel groups study aimed to evaluate the safety, tolerability and the efficacy of riociguat compared with placebo in patients with sickle cell disease (SCD).

The purpose of this study is to evaluate the safety of repeat administration of MST-188 during vaso-occlusive crisis of sickle cell disease. Additionally, this study will evaluate the development of acute chest syndrome during VOC and re-hospitalization for recurrence of VOC.

This study will evaluate the use of reduced intensity conditioning regimen in patients with high risk hemoglobinopathy Sickle Cell and B-Thalassemia Major in combination with standard immunosuppressive medications, followed by a routine stem cell transplant in order to assess whether or not it is as effective as myeloablative high dose chemotherapy and transplant.

The primary objective of the 1701-202 STRONG SCD study is to evaluate the safety and tolerability of different dose levels of IW-1701 compared with placebo when administered daily for approximately 12 weeks to patients with stable SCD. Exploratory objectives include evaluation of pharmacokinetic (PK) as well as evaluation of the effect of IW-1701 on symptoms of SCD, health-related quality of life, and biomarkers of pharmacodynamic (PD) activity.

The objective of this study is to determine the feasibility and acceptability of SCThrive, a an innovative, technology-enhanced, group self-management intervention that uses a mixed in-person and online format and supported by a tailored mHealth tool, iManage. The study will also evaluate the initial efficacy of SCThrive for increasing behavioral activation (BA) in adolescents with Sickle Cell Disease (SCD) ages 13 to 21. The investigators hypothesize that participants in the SCThrive group will show greater BA (primary outcome) at post-treatment than the attention control group, and that participants in the SCThrive group will continue to show significantly greater BA at the six week follow-up compared to the attention control group. Investigators will also explore whether SCThrive is associated with greater improvements in self-management behaviors and quality of life (secondary outcome) compared to attention control at the six-week follow-up assessment.
