Filter by:This study is a first-in-human, single-arm, open-label Phase I/II study of nula-cel in approximately 15 participants, diagnosed with severe Sickle Cell Disease. The primary objective is to evaluate safety of the treatment in this patient population, as well as preliminary efficacy and pharmacodynamic data.
The purpose of this study is to investigate the effect of VIT-2763 on markers of hemolysis (breakdown in red blood cells) in sickle cell disease (SCD). The safety, tolerability and clinical beneficial effects of VIT-2763 for the treatment of SCD are also explored.
With recent advances in gene editing, gene therapy is becoming a viable curative treatment option for sickle cell disease. In order to do genetic manipulation, investigators need to collect hematopoietic stem cells from patients with sickle cell disease. In this study, investigators want to study the safety and feasibility of collecting peripheral blood stem cells from pediatric and young adult patients with sickle cell disease after administering plerixafor. Studying these peripheral blood stem cells will help in optimizing the yield of peripheral CD34+ cells from pediatric and young adult patients with sickle cell disease, which in turn will help to develop better gene therapies for these patients. Primary Objectives - Determine the safety profile associated with administration of plerixafor in pediatric and young adult patients with sickle cell disease (SCD). - To estimate the number of CD34+ cells/kg of body weight that can be collected with peripheral apheresis after administration of plerixafor in pediatric and young adult patients with SCD. Exploratory Objectives - To describe the kinetics of CD34+ cell mobilization in peripheral blood after - + cells obtained from pediatric and young adult patients with SCD. - To study the effect of hydroxyurea therapy on senescence in plerixafor-mobilized CD34+ cells obtained from pediatric and young adult patients with SCD.
Sickle cell disease (SCD) is the most common genetic disease, affecting about 25 million people worldwide. Approximately 150,000 Nigerian children are born each year with sickle cell disease (SCD), making it the country with the largest burden of SCD in the world. Recent advancements in care for children with SCA have translated into improved survival of children in both high and low-resource settings. However, more complications of SCD are seen in those who survive to adulthood. Silent cerebral infarcts (SCI) and strokes are among the most devastating complications of SCD, affecting 40% and 10% of children, respectively. The overall goal of this study is to extend the Investigator's successful capacity-building effort in the assessment of neurological morbidity in children with SCD living in northern Nigeria (Kano) to young adults with SCD living in the same region. About 50% of all adults with SCD live in Nigeria. Despite the high prevalence of SCD in Africa, the neurological morbidity is not well characterized, limiting opportunities for primary and secondary stroke prevention strategies. At least 50% of young adults with sickle cell anemia (SCA), the most severe form of the disease, will have SCIs and an estimated 10% will have strokes, based on studies in high-resource settings. In high-resource settings, screening for abnormal transcranial Doppler (TCD) velocities in children with SCA, coupled with regular blood transfusion has resulted in a 92% reduction of relative risk for strokes. Despite this effective strategy, regular blood transfusion therapy does not seem sustainable in sub-Saharan Africa due to shortages and the risk of transfusion transmissible infections. Additionally, there is a lack of evidence-based stroke prevention strategies in young adults with SCA, either in the high-income or in low-resource settings. Based on the foregoing, the Investigators propose to determine the prevalence of neurological injury (overt stroke, transient ischemic attacks, and silent cerebral infarcts) in young adults at the transition age from 16-25 years. The Investigators will also, for the first time, assess conventional risk factors of stroke in the general population to determine whether a different prevention strategy is required to reduce the incidence of neurological injury in this high-risk population.
Sickle Cell Anemia (SCA) occurs in 300,000 newborns per year in the world, with 150,000 affected births in Nigeria, alone. With improvement in survival for children with SCA in both high- and low-resource countries, neurological morbidity is an emerging significant public health challenge, particularly in countries with a high rate of sickle cell disease (SCD). Both silent cerebral infarcts (SCI) and overt strokes result in significant neurological morbidity and premature death. Five NIH-funded randomized controlled trials (RCT) demonstrated that regular blood transfusion or hydroxyurea therapy are efficacious treatments for primary and secondary stroke prevention in children with SCA. Despite the observation that at least 99% of children with SCA in high-resource settings reach adulthood, and approximately 60% of adults will experience one or more strokes (~50% with SCI and ~10% with overt strokes) and the high disease-burden in Nigeria, the prevalence and incidence rates of new and recurrent stroke (overt and silent strokes)have not been collected systematically in children and young adults (16-25 years old) with SCA. In the last decade, there has been growing use of stroke registries in economically advanced nations, particularly for epidemiological purposes of trend analysis, clinical effectiveness, compliance to guidelines, assessment of implementation, adoption of novel techniques, and quality improvement process. For the first time in clinical centers in Nigeria, the Investigators will conduct an observational epidemiological study to document the prevalence and track the incidence of new and recurrent strokes in children and young adults with SCD. The Investigators will create a stroke registry referred to as the Afolabi Stroke Registry for Children and Young Adults with Sickle Cell Disease in Nigeria. The overall purpose of the stroke registry is to document the natural history of SCD in a low-resource setting and to improve the quality of the care of children and young adults with SCD living in Nigeria.
This project will promote the development of transdisciplinary analyses. Neuropsychological disorders will be explored with the usual appropriate tests done by psychologists and neuropsychologists regularly involved in the management of sickle cell disease affected children. For the social sciences' component, various methods will be used: Measure of the Life habits (MHAVIE), Measure of Environmental Quality (MQE) and semi-guided interviews will complete the collection of qualitative data. The expected results concern the identification of the barriers or facilitators the sickle cell patients might face in their social participation, whether they are affected or not by neurological disorders.
This clinical trial studies the effect of pre-transplant immunosuppression (PTIS) and donor stem cell transplant in treating patients with severe blood diseases (hemoglobinopathies). PTIS helps prepare the body for the transplant and lowers the risk of developing graft versus host disease (GVHD). Hematopoietic cells are found in the bone marrow and produce blood cells. Hematopoietic cell transplantation (HCT) injects healthy hematopoietic cells into the body to support blood cell production. PTIS and HCT may help to control severe hemoglobinopathies.
This is an open label, non-randomized, 2-center, phase 1/2 trial of a single infusion of sickle allele modified cluster of differentiation (CD34+) hematopoietic stem progenitor cells (HSPCs) in subjects with in subjects ≥12 years old to 35 years old severe Sickle Cell Disease (SCD). The study will evaluate the hematopoietic stem cell transplantation (HSCT) using CRISPR/Cas9 edited red blood cells (known as CRISPR_SCD001 Drug Product).
The purpose of this project is to develop novel approaches to promote health and longevity while enhancing quality of life among persons with Sickle cell disease (SCD). Therefore, investigators are aiming to adapt an evidence-based exercise intervention for adults with SCD informed by culturally- relevant and biologic factors and pre-test the adapted exercise program in a small sample of adults with SCD.
The management of pain in the emergency department is a major issue, especially for sickle cell patients who regularly consult for vaso-occlusive seizure (VOS). The place of virtual reality remains to be defined in a busy environment, in which the permanence of care generates a significant turn over of medical and paramedical personnel. With Its immersive nature, allowing the patient to detach from his immediate environment, wich is often stressful for patients, we can hope that in multimodal management, Virtual Reality (VR) can contribute to a faster reduction in pain with lower doses of morphine, but so far we have no data. Our pilot study aims to assess the effectiveness, feasibility and tolerance of adding virtual reality to the management of VOS in sickle cell patients in the ER.
