Filter by: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.
The purpose of this research study is to learn about ways to help children and adults with sickle cell disease who are taking the medication, hydroxyurea.
Sickle cell disease (SCD) is an inherited disorder with chronic multi-system manifestations affecting 100,000 individuals in the US, largely of minority origin and associated with substantial morbidity, premature mortality, individual suffering, healthcare costs and loss of productivity. Disease modifying treatments such as hydroxyurea, chronic blood transfusion and curative bone marrow transplantation are offered to patients based on physician preference and current practice informed by clinical trials. Decision aids are tools that could help translate evidence from these sources into practice by helping clinicians involve patients in making deliberate choices based on accessible information about the options available and their outcomes and to help them make decisions based on their values and preferences. The overarching goal of this project is to implement a web based decision aid individualized to patient characteristics to help patients with SCD achieve more accurate perception of risks and benefits of treatment options and make decisions in congruence with their values and preferences. Investigators will use a randomized controlled trial of the effectiveness of a web-based decision aid to give patients accurate information about risks and benefits of therapies that enable patients to make decisions based on their individual values and preferences.
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 purpose of this study is to assess the maximum tolerated dose, safety and pharmacokinetics of an investigational drug, intravenous (IV) citrulline, in subjects in steady-state sickle cell disease.
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 assess the safety, tolerability, pharmacokinetic, and pharmacodynamic effects of GBT440 compared with placebo in healthy subjects and subjects with sickle cell disease (SCD).
Streptococcus pneumoniae is the major cause of bacterial infection in patients with sickle cells disease. The 23-valent pneumococcal polysaccharide vaccine (PSV) is supposed to be poorly immunogenic in these patients. We want to evaluate whether a prime with a 13-valent pneumococcal conjugate vaccine (PCV), able to induce immunologic memory, would improve the immune response against SP polysaccharides (SPP). Primary objective: To evaluate and compare the specific antibody response to a prime-boost vaccine strategy combining PCV prime at W0 followed by the administration of PSV boost at W4, to the administration of PSV alone at W4 in patients with sickle cells disease. Secondary objectives: Evaluation and comparison of the specific antibody response to the thirteen pneumococcal serotypes shared by the PCV and PSV vaccines, 4 weeks after the single PSV vaccination for patients from Group 1 or 4 weeks after the boost PSV vaccination for patients from group 2. Evaluation of the duration of the specific antibody response at W24 and 96. Evaluation of the T CD4 lymphocyte response to the CRM 197 protein. Safety of the vaccines. Study Design: Randomised, monocentric, controlled phase II study of the immunological efficacy of a prime boost strategy combining the sequential administration of the PCV and PSV, compared to the administration of the PSV alone. 180 adults patients with sickle cells disease will be included. The primary endpoint : proportion of responders at W8 to at least 10 of thirteen serotypes. Secondary endpoints : Proportion of responders at W8 according to 4 categories of responders: 5-7; 3-4; 2-1 and 0. Evaluation of the pneumococcal opsonophagocytic activity (OPA) at baseline and W8 for each serotype, defined as the proportion of patients with OPA > 1:8 geometric mean of the specific antibody titers proportion of patients who experienced an increase of specific antibody levels 1 g/ml. Evaluation of the priming effect of the PCV vaccine in the group 1. Duration of the specific antibody responses at week 24 and W96. CD4 T lymphocyte responses to the CRM 197 protein (proliferative and cytokine production) at weeks 0, 8 and 12. Safety of the vaccines frequency of Streptococcus pneumoniae infections. Statistical Considerations: With a sample size of 180 patients, and a randomization ration of 1:1, the study will have a power of at least 90% to show a difference of 25% category between the group receiving PCV and PSV vs the group receiving PSV alone (two-sided type I error = 5%). The primary comparison between both groups will be performed using a Chi2 test for independent groups or a Fisher exact test where appropriate.
This study aims to develop an effective, brief, family-based intervention targeting quality of life and school functioning for youth with sickle cell disease. Utilizing a randomized, delayed control group intervention methodology, the present study will systematically document the effectiveness of a family-based, one-day intervention plus booster phone calls to improve quality of life and increase school functioning for children with sickle cell disease transitioning to school and their families.
The purpose of this research study is to: 1. Investigate the effects of a single 20-minute music therapy intervention with a music therapist on the pain intensity, pain relief, and mood of adult patients with sickle cell disease as compared to: 1. Adult patients with SCD who listen to their preferred music for 20 minutes without the presence of a music therapist (music listening group) 2. Adult patients with SCD who receive standard care alone (control group) 2. Determine the feasibility (delivery, acceptability, and usefulness) of the music therapy intervention for pain management
