Filter by:The purpose of this study is to assess the tolerance and efficacy of mobilizing hematopoietic stem cells after a single injection of plerixafor (0.24mg/kg) in 3 adult patients (or 5, if results of the first 3 patients are not reproducible) affected by sickle cell disease.
The purpose of the study is to develop patient-provider clinical support tools to improve clinical practice, patient self-management, and disease outcomes in sickle cell disease during transition to adult care. The investigators hypothesize that these clinical support tools (patient tool, provider tool, and patient/parent web-based portal) will be feasible, user friendly, and beneficial. The investigators hypothesize that participants will demonstrate better disease self-efficacy at the end of the 6 week intervention and maintain these gains during the follow-up period (up to 1 year post-intervention).
Multi-phase, patient navigator-based program in the Richmond and Tidewater regions of Virginia to demonstrate: 1. the feasibility of using patient navigators to improve the percentage of children and adult (age 15 and older) patients with sickle cell disease (SCD) in SCD specialty care 2. the efficacy of using patient navigators to improve hydroxyurea (HU) (re-)initiation and adherence among adult patients with SCD eligible for HU (Patient navigators may also be known as public health workers.)
Acute and chronic pulmonary complications with concomitant inflammatory response are a leading cause of morbidity and mortality in children with sickle cell disease (SCD). Acute chest syndrome (ACS), defined broadly as an increase in respiratory effort, fever and new radiodensity on chest x-ray, is a major cause of death in children and adults with SCD. There is a high rate of ACS in children between 1 and 4 years of age that is associated with an asthma diagnosis, and children with ACS events before 4 years of age have a 50% rate of being hospitalized for either ACS or pain within 1 year of admission. For children with SCD that develop ACS, the investigators propose that the use of budesonide inhalation suspension (BIS) will attenuate pulmonary inflammation after an ACS episode and will decrease future vaso-occlusive pain and ACS episodes. Through a single-arm prospective feasibility trial and in preparation for a limited-institution randomized trial, the investigators plan to test the following primary hypothesis for a phase III definitive trial: In children with SCD admitted to the hospital for an ACS episode between 1 and 4 years of age, low dose BIS for 6 months will result in a 50% reduction in the recurrent incidence rate of ACS or pain requiring hospitalization. Through this trial, the investigators will determine the acceptability of and adherence to BIS in the study population. The investigators will track respiratory symptoms in cases versus controls over 6 months. Finally, the investigators will explore the impact of BIS on biological correlates (sVCAM-1).
This is a clinical study evaluating the efficacy and safety of rivipansel (GMI-1070) in treating subjects with sickle cell disease (SCD) who are 6 years of age or older experiencing a pain crisis necessitating hospitalization.
This is a Phase 1/2, open label, safety, and efficacy study of the administration of LentiGlobin BB305 Drug Product to participants with either transfusion dependent beta-thalassemia (TDT) or sickle cell disease (SCD).
The vast majority of births with sickle cell disease (SCD) occur in Africa and 90% are thought to die before the age of five. Hydroxyurea (HU) is the only drug approved by the FDA for the treatment of sickle cell anemia. Although HU is used to treat small numbers of patients in Africa, cost, fear of toxicity, and lack of awareness and availability limit its use. The leukopenia that may be seen with HU raises the possibility of increased susceptibility to infection. Risk stratification - i.e., identification of patients most likely to benefit- could focus therapy and provide confidence that the risk:benefit ratio is favorable. Several clinical measures of future risk are well defined and findings on modifier genes in the US, primarily related to fetal hemoglobin (HbF), have further improved risk prediction. Whether the genetic variants predict severity in Africa is not known. The investigators have established a SCD cohort in Ibadan, Nigeria. In the first phase of this research the investigators will implement clinical risk examinations and assess the relationship between clinical characteristics (including levels of HbF) and known genetic markers. As a proxy for a birth cohort, the investigators will compare the frequency of the genetic markers in adult patients (i.e., "survivors") to children. In the second phase the investigators will randomize 40 high risk adult patients to fixed low dose HU or no HU treatment in a crossover design and monitor hematologic and physiologic parameters to document hematologic effects and safety. This work will lay the basis for a large-scale trial to document safety and efficacy.
Youth diagnosed with sickle cell disease (SCD) may have difficulty taking medication as prescribed (adherence). Hydroxyurea (HU) is one medication that youth may take to help manage SCD. Electronic adherence monitoring is widely considered the gold standard in objective adherence measurement. These monitors provide continuous, real-time records of medication adherence and reveal problematic behavior patterns, including underdosing, overdosing, delayed dosing, "drug holidays" (i.e. where individuals do not take medications for a specified interval of time), and "white coat" adherence (i.e., a pattern of drug adherence as a function of time where individuals display good adherence immediately before and after clinic attendance with worsening adherence in the period between). Overall, electronic adherence measures are considered valid, reliable, and accurate, with clear advantages over pharmacy refill records, physician estimates and self-report measures. Currently, only one electronic measure capable of monitoring medications in both pill and liquid form is being manufactured: WisePill and WiseBag. While data are limited regarding its validity and reliability, preliminary data support the use of Wise technology to measure adherence to medication. The current study will determine the Wise device's ability to feasibly measure adherence to liquid and solid form HU medication in a pediatric SCD population.
This is a non-randomized, open label, multi-site, single dose, Phase 1/2 study in approximately 50 adults and adolescents with severe SCD. The study will evaluate hematopoietic stem cell (HSC) transplantation (HSCT) using bb1111 (also known as LentiGlobin BB305 Drug Product for SCD).
Purpose: Assess whether intensive training with education and daily remote monitoring with provider involvement has a lasting positive impact on adherence to medication management. The study will seek to enroll 25 subjects with sickle cell disease or thalassemia, and less than 100% compliance for taking iron chelators in the previous three month prior to participation in the study. Subjects will be asked to monitor their daily iron chelator administration by taking a video recording of preparing it and ingesting at least one sip. Subjects will also use a medication log to record daily administration of medication, and meet with study staff monthly for educational activities. The data collected will be analyzed to describe patient adherence and comfort level with the process of daily recording of medication management. Mean percent adherence in the pre-study periods and each of the study periods will be analyzed and compared.
