Hydroxyurea Optimization Through Precision Study

HOPS
Start date: December 31, 2018
Phase: Phase 3
Study type: Interventional

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.

Pediatric -Adult Care Transition Program of Patients With Sickle Cell Disease

DREPADO
Start date: January 2019
Phase: N/A
Study type: Interventional

Background The pediatric-adult care transition is a risk-disrupting time for patients with chronic disease. This care transition takes place during adolescence; a period of psychological upheavals and adaptations of family roles. During this period, medication adherence is non-optimal and absenteeism at medical appointments is high. Sickle cell disease (SCD) is the first genetic disease detected in France. It is chronic disease characterized by frequent painful vaso-occlusive crises (VOC) requiring emergency hospitalization when they are severe. Other serious complications are acute chest syndromes (ACS) and stroke. In order to improve the health status of teenagers with sickle cell disease, it is necessary to anticipate this care transition and to involve the pediatric and adult sectors. The biopsychosocial health approach and the Social-Ecological Model of Adolescent and Young Adult Readiness to Transition (SMART) describe a care transition integrating bioclinical and psychosocial factors such as integration of the patient's family, education on disease and therapeutics, psychological management of pain and medico-social orientation. The pediatric-adult transition program proposed is based on this biopsychosocial approach. It aims to improve the health status of adolescents with SCD, their quality of life and the use of health care service. Objective of the study To assess the impact of a pediatric-adult transition program on the incidence of sickle-cell-related complications leading to hospitalization on 24-months after transfer to the adult sector. The evaluation focuses on severe complications leading to hospitalization, such as VOC, ACS, and stroke. Study design Multicenter Open-label individual Randomized Controlled Trial Population : Patients aged at least 16 years old with sickle cell disease, and their parents (or legal representatives Number of subject : 196 patients (98 patients by arm) The study will last 24 months Expected results For patients and families Better health and quality of life for patients is expected, including better use of medical care after the transition program. It is also expected a better experience of the pediatric-adult care transition and indirectly a better experience of intrafamilial relations. For health professionals This project is expected to provide solutions to improve the pediatric-adult care transition of patients with chronic disease. Indeed, the methodological quality of the study will make it possible to evaluate the efficiency of the proposed program, to possibly adapt it and test it to other chronic diseases presenting the same care transition problematic. In terms of public health SCD mainly affects populations of sub-Saharan origin, with low visibility and high social vulnerability. By focusing on this population, this project will reduce the social inequalities in health, experienced by patients with SCD and their families. By improving the health, quality of life and care of patients with SCD, this project is expected to decrease the cost of the pediatric-adult care transition period.

Inhaled Mometasone to Promote Reduction in Vasoocclusive Events 2

IMPROVE2
Start date: November 29, 2018
Phase: Phase 2
Study type: Interventional

The study team proposes a triple-blind, placebo-controlled, phase II clinical trial of once-daily inhaled mometasone for 48 weeks (with 4-week washout at study completion) in individuals with Sickle Cell Disease (SCD) who report episodic cough or wheeze (ECW) but do not have asthma. Patients will be recruited from and followed in SCD clinics at participating sites. The primary endpoint will be a reduction in sVCAM level of 20% or more in comparison to placebo.

NCT ID: NCT03753854 Recruiting - Sickle Cell Disease Clinical Trials

Sleep Apnea in Sickle Cell Disease

DREPAPNEE
Start date: May 28, 2018
Phase: N/A
Study type: Interventional

Despite the fact that obstructive sleep apnoea (OSA) is highly prevalent in the sickle cell population, studies focusing on the associations of the two diseases and their common pathophysiological mechanisms are scarce. OSA is one of the most common conditions responsible for hemoglobin desaturation. The nocturnal hemoglobin desaturation occurring in some sickle cell disease (SCD) patients with OSA could trigger hemoglobin S polymerization and red blood cell (RBC) sickling, leading to further blood rheological alterations, hence increasing the risks for VOC. Moreover, OSA has been demonstrated to increase oxidative stress and inflammation in non Sickle Cell Disease (SCD) patients, which, in SCD patients, could increase the risk for complications. Finally, OSA is accompanied by impaired vascular function and autonomic nervous system dysfunction in the general population. Indeed, the presence of OSA in SCD could increase the clinical severity of patients and the frequency of VOC.

MAP to Provide Access to Crizanlizumab, for Sickle Cell Disease Patients

Start date: n/a
Phase:
Study type: Expanded Access

The purpose of this Cohort Treatment Plan is to allow access to crizanlizumab (SEG101) for eligible patients diagnosed with sickle cell disease (SCD) to prevent or reduce the frequency of vaso-occlusive crises (VOC). The patient's Treating Physician should follow the suggested treatment guidelines and comply with all local health authority regulations.

NCT ID: NCT03719729 Recruiting - Sickle Cell Disease Clinical Trials

Rifaximin to Modify the Disease Course in Sickle Cell Disease

Start date: August 22, 2018
Phase: Phase 2
Study type: Interventional

In this single-arm, one-stage Phase II study, we hypothesize that gut decontamination with rifaximin will reduce the frequency of hospital admission due to painful crisis in patients with SCD. We will accrue 20 SCD patients who had at least two hospital admissions in the previous 12 months. These patients will receive rifaximin 550 mg twice a day for a total of 12 months. This following clinical parameters will be measured: 1. Changes in the annual rate of hospital admissions due to painful crisis; 2. Changes in the annual rate of days hospitalized; 3. Annual rates of uncomplicated crises; 4. Annual rate of acute chest syndrome; 5. Changes in the quality of life; and 6). Toxicities. The following laboratory parameters will be measured: 1. Changes in the number of circulating activated neutrophils; 2. Changes in the intestinal microbiome diversity; 3. Changes in the urinary 3-indoxyl sulfate levels; 4. Changes in the serum biomarkers of intestinal permeability (lipopolysaccharides; zonulin, citrulline, and fatty acid binding proteins).

Cerebrovascular Reserve and White Matter Disease in Patients With Chronic Anemia

CVR
Start date: July 15, 2018
Phase:
Study type: Observational

This is primarily an observational trial in patients with chronic anemia syndromes (sickle cell disease and thalassemia) and control subjects. The key purpose is to understand how brain blood flow reserve (the ability of the brain to increase its flow in response to stress) is altered in patients with chronic anemia. Since this parameter may depend on anemia severity, we will perform the MRI monitoring prior to and following clinically indicated transfusions in a subset of patients. Most patients will already be prescribed hydroxyurea as part of their standard of care. Since hydroxyurea could impact brain blood flow, there is also a small pilot study (20 patients, nonrandomized, open label) where MRI imaging will be performed prior to and following administration of hydroxyurea up to maximum tolerated dose. The study will enroll 90 adult subjects with transfusion independent sickle cell disease (70 SS, 10 SC, 10 Sβ0) and 60 patients with transfusion-dependent sickle cell disease. It will also include 10 transfusion independent thalassemia patients and 20 transfusion dependent thalassemia patients as well as 40 control subjects recruited from first degree relatives of the sickle cell disease population. All eligible subjects will be asked to provide informed consent before participating in the study.
