Filter by:Hydroxyurea Optimization through Precision Study (HOPS) is a prospective, multi-center, randomized trial that will directly compare a novel, individualized dosing strategy of hydroxyurea to standard weight-based dosing for children with SCA. The primary objective of the study is to evaluate whether a pharmacokinetics-based starting hydroxyurea dose thieves superior fetal hemoglobin response to to standard weight-based initial dosing. Patients will be recruited from the pediatric sickle cell clinic at Cincinnati Children's Hospital Medical Center and from additional pediatric sickle cell centers within the United States.
The purpose of this study is to evaluate what effect, if any, mismatched unrelated volunteer donor and/or haploidentical related donor stem cell transplant may have on severe sickle cell disease and other transfusion dependent anemias. By using mismatched unrelated volunteer donor and/or haploidentical related donor stem cells, this study will increase the number of patients who can undergo a stem cell transplant for their specified disease. Additionally, using a T-cell depleted approach should reduce the incidence of graft-versus-host disease which would otherwise be increased in a mismatched transplant setting.
Except for children with HIV, all recommendations for treatment of childhood malnutrition are for children < 5 years of age. The overall goal of this randomized controlled nutrition feasibility trial is to identify whether families of children with sickle cell disease (SCD) 5 years and older agree to participate over a 12-week period. The investigators will also establish a safety protocol for monitoring potential complications associated with treating severe malnutrition in children 5 years and older with and without SCD, in a low-resource setting.
The goal of the study is to understand how best to help parents of young children with sickle cell disease and their clinicians have a shared discussion about hydroxyurea (one that takes into account medical evidence and parent values and preferences). The study will compare two methods to help clinicians facilitate this-a clinician pocket guide and a clinician hydroxyurea shared decision making toolkit-in a group of parents of children ages 0-5 with sickle cell disease. The investigators hope that both methods lead to parents reaching a high-quality, well-informed decision. In addition, the team hopes to demonstrate that parents who experience a shared decision will have lower anxiety and decisional uncertainty. The researchers also expect these parents to be more likely to choose hydroxyurea and that their children will have less pain, fewer hospitalizations, better developmental outcomes, and higher quality of life. The project team hopes to show that the toolkit method is easy for clinicians to use and gives parents the support needed to make an informed decision.
The Novel use Of Hydroxyurea in an African Region with Malaria (NOHARM) study is the first placebo-controlled randomized clinical trial of hydroxyurea treatment in a malaria endemic region. NOHARM has now achieved full enrollment; all children have completed the blinded portion of the protocol and are in the open-label study treatment portion. This extension study of maximum tolerated dose (MTD), addresses the next critical set of questions about the optimal dosing and monitoring of hydroxyurea treatment for children with SCA in low-resource settings. By providing guidance about optimal hydroxyurea treatment, the NOHARM MTD Study will directly inform policies that can transform the health of African children living with SCA.
The CADRE study is a multinational observational cohort of patients with sickle-cell disease (SCD) in five west and central sub-Saharan African countries. The aim of this project is to describe the incidence and assess the predictive factors of SCD-related micro- and macro-vascular complications in sub-Saharan Africa.
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.
To examine the pharmacokinetics and distribution of oral hydroxyurea when administered as a single dose to lactating women
The purpose of this study is to determine whether metformin is effective in the treatment for sickle cell anemia (SCA).
The study assesses the efficacy, safety and tolerability of ACZ885 (canakinumab) in pediatric and young adult patients with sickle cell anemia (SCA).
