Active clinical trials for "Anemia, Sickle Cell"

L-glutamine has been approved in the US to reduce the acute complications of sickle cell disease (SCD) in adult and pediatric patients 5 years of age and older. The purpose of this single-center, open-label, phase 4 study is to evaluate the pharmacokinetic characteristics and safety of L-glutamine in patients with SCD.

The management of pain in the emergency department is a major issue, especially for sickle cell patients who regularly consult for vaso-occlusive seizure (VOS). The place of virtual reality remains to be defined in a busy environment, in which the permanence of care generates a significant turn over of medical and paramedical personnel. With Its immersive nature, allowing the patient to detach from his immediate environment, wich is often stressful for patients, we can hope that in multimodal management, Virtual Reality (VR) can contribute to a faster reduction in pain with lower doses of morphine, but so far we have no data. Our pilot study aims to assess the effectiveness, feasibility and tolerance of adding virtual reality to the management of VOS in sickle cell patients in the ER.

The purpose of this study is to find out whether a web-based intervention using a mobile device is helpful for teens learning to care for and manage symptoms of sickle cell disease. The intervention lasts 12 weeks with a 3-month follow up period, and uses a smartphone or a tablet.

This study is being conducted to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of an investigational drug, PF-04447943, in subjects with stable sickle cell disease with and without co-administration with hydroxyurea. This study will also aid in selecting the doses for future studies and evaluation of substances in the blood which may help access the effectiveness of the drug.

This is a single arm, phase I study to assess the tolerability of abatacept when combined with cyclosporine and mycophenolate mofetil as graft versus host disease prophylaxis in children undergoing unrelated hematopoietic stem cell transplant for serious non-malignant diseases as well as to assess the immunological effects of abatacept. Participants will be followed for 2 years.

The primary goal of this randomized, controlled, open-label study is to determine the efficacy of AccuveinV400 (a transillumination veins device) to facilitate peripheral intravenous (IVP) catheter placement during a vaso-oclusive crisis. The investigators hypothesized that the number of attempts to a successful placement of a peripheral IV, our primary outcome, would be shorter with the assistance of the Accuvein V400. It is also expected that AccuveinV400 will reduce the time of the procedure, the rate of failure, the technique-related pain.

Sickle cell disease (SCD) is a common genetic disorder characterized by episodes of pain, yet assessments to identify type, intensity, frequency, and phase of pain among SCD adolescents is lacking. Research shows that interactive gaming technology can enhance adolescents' learning, and can be especially effective in delivering health-related messages and tools to improve their self-care. Pinpoint is an interactive gaming tablet app that will be developed with the significant input of clinical experts to assist SCD teens with better identification and self-report of their pain.

Many youth with chronic disease have difficulty taking medication every day and therefore do not receive full benefit from treatment. Sickle Cell Disease (SCD) is an inherited blood disease that affects African Americans and other underserved communities. Hydroxyurea (HU) is the sole FDA-approved drug therapy for SCD and is highly effective and improves quality of life. The proposed study, a 5-site four-year randomized control trial (RCT), builds upon the investigators' recent feasibility study of the same title. Overall goals are reducing barriers to HU use and improving adherence for youth 10-18 years through creation of a daily medication habit. The goal of the proposed multi-site study is to test the efficacy of the HABIT intervention at 6 months and sustainability of the effect at 12 months.

To evaluate the relative bioavailability of ticagrelor for the different formulations. A randomized cross-over design has been chosen to minimize the effects of between-subject variability and any period effects on the overall results.

The constitution of blood relies upon hematopoietic stem cells (HSCs), which stay in the bone marrow and differentiate to all lineages of peripheral blood cells. HSC transplantation is the only curative option currently available for sickle cell disease (SCD) patients either via allogeneic HSC transplantation or HSC-targeted gene therapy. Granulocyte-colony stimulating factor (G-CSF)- mobilized HSCs are frequently utilized in the adult setting of HSC transplantation because of the faster hematologic recovery as compared to bone marrow. As an autologous HSC source for gene therapy, bone marrow harvest has been generally employed since G-CSF has been prohibitive in SCD patients due to granulocyte stimulation and the associated reports of vaso-occlusive crises, multi-organ failure, and death. However, when bone marrow harvest is used, the amounts of collected cells are limited and anesthesia is required. In order to obtain HSCs in large numbers without anesthesia, patients will undergo mobilization followed by large volume apheresis. Plerixafor is an alternative treatment for mobilization without direct stimulation to granulocytes, and it is theoretically applicable for SCD patients. The primary endpoint of this study is to obtain sufficient amounts of HSCs collected from the peripheral blood in SCD patients after plerixafor mobilization with an acceptable safety profile. The harvested products will be stored as backup for patients undergoing gene therapy as well as allogeneic HSC transplantation.
