Filter by:This is a single-dose, open-label study in pediatric participants with severe SCD and hydroxyurea (HU) failure or intolerance. The study will evaluate the safety and efficacy of autologous CRISPR-Cas9 modified CD34+ human hematopoietic stem and progenitor cells (hHSPCs) (CTX001).
The study will use web-based data collection (SCKnowIQ) and intervention delivery strategies enhanced by nudges and tailored boosters in a sample of 430 adult men and women, aged 18-45 yr with SCD (Sickle Cell Disease) or SCT (Sickle Cell Trait), at-risk, and planning within 2 years to have a child free of SCD.
This is a randomised, controlled, double-blind, placebo trial of HBOT (intervention) superiority in the treatment of VOC in SCD, to demonstrate the effectiveness of HBOT for the decrease in pain level in the treatment of SCD-VOC.
Sickle cell anemia (SCA) is among the world's most common and devastating blood disorders, affecting more than 300,000 newborns per year. Most infants with SCA are born in the low-resource settings of sub- Saharan Africa, where an estimated 50-90% will die before 5 years of age due to lack of early diagnosis and appropriate care. Hydroxyurea is a safe and effective once-daily oral medication that has become the standard of care for the treatment of children with SCA in high-resource settings. There is now a growing body of evidence to support the safety and clinical benefits of hydroxyurea for the treatment of SCA in sub-Saharan Africa. The requirement for frequent laboratory monitoring, uncertainties about appropriate, most effective dosing, and the concern for hematologic laboratory toxicities, however, will continue to limit widespread hydroxyurea utilization and real-world effectiveness. The investigators have recently developed and prospectively evaluated an individualized, pharmacokinetics-guided hydroxyurea dosing strategy for children with SCA that has demonstrated optimal clinical and laboratory benefits with minimal toxicity. In this research study, the investigators aim to extend this precision medicine approach to Africa.
This will be an open-label, dose escalating study with a starting dose of 2mg. Up to 6 additional cohorts will be enrolled at subsequently higher doses of 4mg, 8mg, 10mg, 12mg, 16mg, and 32mg. In each dose escalation cohort, each dose will be taken orally, once daily, for 8 weeks.
In this study the investigators will prospectively investigate whether the addition of a 3-months long preconditioning with azathioprine to the alemtuzumab/TBI non-myeloablative conditioning results in improved disease-free survival and donor chimerism after allo-SCT in SCD patients. Furthermore, the investigators will evaluate whether azathioprine/hydroxyurea preconditioning leads to more patients being able to taper and discontinue sirolimus at 12 months post-transplantation.
This is a multicenter prospective, longitudinal cohort study which will evaluate the predictive capacity of machine learning (ML) models for progression of CKD in eligible patients for a minimum of 12 months and potentially for up to 4 years.
Sickle cell disease is the subject of targeted neonatal screening (carried out when one of the two parents is from an endemic country - sub-Saharan Africa, South-East Asia, Central America, the Caribbean) during the Guthrie test. Haemolysis, which results from the abnormality of the haemoglobin, and the vascular activation it causes, are responsible for multiple organ damage. Major sickle cell syndromes (MSC), by several mechanisms, are responsible for a wide range of renal damage, culminating in end-stage renal failure at an average age of 45 years and with an average survival of 3 years beyond ESRD. The various renal disorders are : glomerular hyperfiltration and then glomerulosclerosis; tubular dysfunction, especially proximal and distal hyposthenuria (a factor in enuresis); papillary necrosis, renal infarction, episodes of acute renal failure during vaso-occlusive crises; dysregulation of the renin-angiotensin system with early arterial hypertension and, more rarely, extra-membranous glomerulonephritis. In the early stages of these conditions, simple paraclinical tests can identify them before the appearance of specific clinical signs. In patients suffering from MDS, the HAS (High Authority of Health) recommends an annual check-up carried out in a Competence Centre. According to the HAS recommendations for annual surveillance, in addition to the search for other organic complications, for renal pathology, only microalbuminuria and renal ultrasound are recommended. However, as the literature shows, microalbuminuria and ultrasound only detect some of these renal disorders and at a very late stage. A large number of publications in adults and, to a lesser degree, in children, demonstrate the correlation between the frequency of acute complications of sickle cell disease (episodes of haemolysis, etc.) and the occurrence of kidney damage.
This study will validate the diagnostic accuracy of a cutaneous hydration sensor. This sensor will also be evaluated for its feasibility as a point-of-care device for the assessment of hydration status and its potential to guide hydration therapy in patients with sickle cell disease (SCD).
Sickle cell disease (SCD) patients ending with mixed mononuclear chimerism after non-myeloablative HSCT with alemtuzumab/TBI conditioning will probably preserve their immune response to vaccinations administered prior to the transplantation and will therefore not need to be revaccinated. Furthermore, SCD patients after haploidentical HSCT might benefit from adoptive transfer of immunity from their donors. To test the first hypothesis, patients undergoing alemtuzumab/TBI HSCT will be vaccinated with a hepatitis B virus (HBV) vaccine before the transplant. To test the second hypothesis, haploidentical and matched related donors will be vaccinated prior to stem cell donation against HBV. Neither the patient nor the donor may previously have been immunized against HBV in all cohorts. Post-transplantation, the investigators will be able to evaluate whether SCD patients preserve their pre-transplant immune response in the post-transplantation period. Furthermore, the investigators will determine whether donors transfer their immunity to HSCT recipients with SCD disease.
