Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Sickle Cell Disease (SCD) impairs oxygen transport to tissue and causes endothelial injury. Thus, therapeutic interventions aim to improve both, but there is an unmet need for biomarkers to determine when intervention is necessary and evaluate the effectiveness of the chosen intervention in individual patients. This study proposes to monitor SCD and its treatment through their impact on cerebral hemodynamics, as the brain is one of the most vulnerable and consequential targets of the disease. Specifically, this study will optimize quantitative magnetic resonance imaging (MRI) and advanced optical spectroscopy techniques such as frequency-domain near-infrared and diffuse correlation spectroscopies (FDNIRS-DCS) to monitor 1) cerebral oxygen transport with measures of cerebral blood flow (CBF), cerebral oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen consumption (CMRO2) and 2) endothelial function with cerebrovascular reactivity (CVR). Additionally, this study aims to monitor baseline cerebral oxygen transport and CVR, as well as changes that occur with treatment (transfusion or genetic therapy to induce fetal hemoglobin) and assess hemoglobinopathy patients with known genotypes and phenotypes. The ultimate goal is to demonstrate the potential of this monitoring approach to select individual SCD subjects for interventions and evaluate individual responses to treatment. Success will help justify inclusion of these modalities in ongoing and future clinical trials of novel SCD therapies.
