Active clinical trials for "Anemia, Sickle Cell"

This is a pilot study, single-blind, randomized, multicenter, therapeutic clinical trial designed to evaluate the feasibility of enrolling infants and toddlers (9 months to 36 months) with sickle cell anemia (SCA; HbSS or HbSβ^0thalassemia), regardless of disease severity, to a therapeutic trial. A prior clinical trial at St. Jude Children's Research Hospital (SJCRH) (BABYHUG, NCT01783990) demonstrated that a fixed dose (20 mg/kg/day) of hydroxyurea was safe and effective in decreasing SCA-related complications in very young children (9-18 months), and largely due to these findings, hydroxyurea is recommended to be offered to all children (≥9 months old) with SCA, independent of disease severity. Nevertheless, children in the treatment arm of BABYHUG continued to experience vaso-occlusive symptoms and to incur organ damage. In clinical trials of older children with SCA, intensification of hydroxyurea to a maximum tolerated dosage (MTD), defined by mild to moderate myelosuppression, may be associated with improved laboratory parameters compared to fixed lower-dosing, but the clinical benefits gained from dose intensification have not been described. Therefore, in this trial, children in the standard treatment arm will receive a fixed dose of hydroxyurea (20 mg/kg/day), and participants in the experimental arm will receive hydroxyurea intensified to MTD, defined by a goal absolute neutrophil count (ANC) of 1500-3000 cells/µL. This trial aims to establish a multicenter infrastructure that will identify, enroll and randomize very young children (9-36 months) to receive fixed dose versus intensified-dose hydroxyurea in a single blinded manner, and to obtain prospective pilot data comparing the clinical and laboratory outcomes between the treatment arms to facilitate design of a definitive phase III trial.

The primary aim of this study is to test the feasibility and acceptability of implementing a multimedia computerized cognitive behavioral therapy (cCBT) program for reducing SCD pain symptoms in a single-arm pilot pragmatic clinical trial. The investigators will recruit 40 SCD patients with chronic pain and/or on chronic opioid pain treatment and randomize them 3:1 to two groups (cCBT and e-Education respectively), randomizing unevenly in order to best gather feasibility data for the cCBT. Both groups will use a mobile app to track daily pain/mood. The cCBT group will receive sessions of the CALM-SCD program to complete via mobile device and will have weekly follow-up with a care coach. The Education group will receive online education modules to complete via mobile device and will also have weekly follow-up with a care coach. The primary outcomes of the trial include feasibility (recruitment, retention, provider and patient feedback) and acceptability (sessions completed) of the CALM-SCD program.

Research has suggested that children with sufficient vitamin D levels undergoing hematopoietic stem cell transplant (HSCT) have improved outcomes, including lower incidences of infection and graft-versus-host disease (GVHD), as well as overall improved survival. However, supplementation in children undergoing HSCT has shown to be a challenge using standard or aggressive supplementation strategies. The primary objective of this study is to determine the safety and efficacy of a single, high dose oral vitamin D (Stoss Therapy) at the start of transplant followed by maintenance supplementation in children undergoing HSCT.

Pain is the primary complication of sickle cell disease (SCD), including vaso-occlusive crises and more persistent, chronic pain. SCD-related pain is associated with significant functional impairment, spanning poor school attendance, decreased quality of life, and stress and mood difficulties. Pharmacological approaches are the first-line treatment for SCD-related pain, but these can be costly and have unwanted side effects. Given limitations from pharmacological approaches and the influence that poor behavioral responses have on disease management and health outcomes suggest a critical need for alternative and adjunctive treatments. Due to gaps in available behavioral treatments specifically designed for addressing common challenges associated with pain management in pediatric SCD, the investigators developed a manualized behavioral therapy protocol by tailoring existing evidence-based treatments. The overall goal of the intervention is to reduce the impact of pain on daily functioning in pediatric SCD. This study will empirically test the feasibility and preliminary efficacy of this intervention for youth with SCD. Children and adolescents with SCD between the ages of 8 and 17 years old (n=20) will be recruited to complete the treatment protocol. Feasibility will be assessed by examining participation and program completion rates, as well as feedback from a treatment acceptability questionnaire and qualitative interview. Participants will complete baseline assessments, weekly questionnaires, and post-treatment assessments (post-intervention assessment, follow-up time points: 1-month following the intervention, and 3-months following the intervention).

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK), and pharmacodynamics (i.e., how the body absorbs, distributes, breaks down, and excretes) of GBT021601, a hemoglobin S (HbS) polymerization inhibitor, in participants with SCD, following single and multiple ascending doses.

The overall purpose of this proposed study is to improve management of vaso-occlusive episodes (VOEs) in adult EDs. We aim to implement NHLBI recommendations for VOE treatment by embedding Individualized Pain Plans (IPPs) in the electronic health record (EHR). The EHR-embedded IPP will serve as a record of patients' SCD genotype and will include analgesic medication recommendations developed by the SCD provider. In this project, we will provide access to the IPP for both adult patients with SCD and ED providers. The proposed multisite study will use a pre-post study design, with a core set of mandatory intervention components and strategies for each participating site and optional components and strategies to allow for intervention adaptation to local needs and resources. The EHR-embedded IPP will be available for all adult ED providers to use as their routine practice, and patients will be invited to participate and enroll in the study. We will use a simplified Technology Acceptance Model to explain the use of the IPP and the RE-AIM framework to assess the Reach, Effectiveness, Adoption, Implementation, and Maintenance of the intervention.

Hemoglobinopathies are the most common life threatening, monogenic disorders in the world. The most common causes of hemoglobinopathies are sickle cell disease and thalassemia. Aim: This study aimed to evaluate the effect of a hemoglobinopathy nursing program on pediatric nursing students' performance.

This is a prospective, interventional, phase II, open-label, multicentre, national, non-comparative study of a single administration of the new dispersible form of hydroxycarbamide at the usual dose in children with sickle cell disease who are already treated with the current form of hydroxycarbamide (Siklos® 100 mg and/or 1000 mg film-coated tablets).

The role of the combination therapy of hydroxyurea and L-Carnitine was studied in thalassemic patients. nevertheless its role in sickle cell anemia patients was not investigated

Sickle cell anemia is a homozygous genetic disease with high prevalence in Brazil. There are changes in conformation and physicochemical properties of red cells that generate varied clinical manifestations among which is chronic hemolytic anemia, cardiovascular diseases, fever, splenic sequestration and usually painful crises. Women with sickle cell anemia have high maternal-fetal and neonatal morbidity and mortality. During pregnancy, there is intensification of maternal anemia, episodes of painful crises; and also, more obstetric risks, such as pre-eclampsia, thromboembolism and hemorrhage. Thus, there is the need for adequate reproductive family planning for this population conducted mainly through hormonal contraception. The World Health Organization recommends that all contraceptive methods may be prescribed for people with sickle cell anemia women, being the progestogen-only contraceptive methods the most indicated due to no changes in venous or arterial thrombosis. Nevertheless, there is need for further scientific evidence as the best contraceptive choice among women with sickle cell anemia in relation to safety, adhesion and reduction of pain crises. The objective of this study is to evaluate the clinical effect through safety of etonogestrel-releasing contraceptive implant in women with sickle cell anemia during twelve months.
