This study is a cooperative investigation funded by the NIH. The project is a collaboration among three major NIH Clinical Translational Science Awardees: 1) UCI (lead site with its affiliate CHOC), 2) Northwestern University (with its affiliate Lurie Children's Hospital), and 3) USC (with its affiliate Children's Hospital of Los Angeles). There is an increasing number of children who, through medical advances, now survive diseases and conditions that were once fatal, but which remain chronic and debilitating. A major challenge to improve both the immediate and long term care and health of such children has been the gap in our understanding of how to assess the biological effects of exercise. Like otherwise healthy children, children with chronic diseases and disabilities want to be physically active. The challenge is to determine what constitutes safe and beneficial level of physical activity when the underlying disease or condition [e.g., cystic fibrosis (CF) or sickle cell disease (SCD)] imposes physiological constraints on exercise that are not present in otherwise healthy children. Current exercise testing protocols were based on studies of athletes and high performing healthy individuals and were designed to test limits of performance at very high-intensity, unphysiological, maximal effort. These approaches are not optimal for children and adolescents with disease and disability. This project (REACH-Revamping Exercise Assessment in Child Health) is designed to address this gap. Cohorts of children will be identified with two major genetic diseases (CF and SCD) and measure exercise responses annually as they progress from early puberty to mid or late puberty over a 3-4year period. In addition, in the light of the pandemic, a group of children will be added who were affected by SARS-CoV-2 and investigate their responses to exercise. SARS-CoV-2 has similar long-term symptoms than CF and SCD have. Novel approaches to assessing physiological responses to exercise using advanced data analytics will be examined in relation to metrics of habitual physical activity, circulating biomarkers of inflammation and growth, leukocyte gene expression, and the impact of the underlying CF, SCD or SARS-CoV-2 condition. The data from this study will help to develop a toolkit of innovative metrics for exercise testing that will be made available to the research and clinical community. Read Less

The objective of this study is to measure the acceptability and impact of the progestin implant on frequency of vaso-occlusive crises, quality of life, and hematologic parameters in women with SCD. Read Less

There is limited information on what causes injury to the heart in individuals with Sickle Cell Disease (SCD). Researchers in this study want to see if decreased blood flow to the heart during stress could be causing the heart damage seen in SCD patients. They also want to test people who don't have SCD to see if their hearts react the same way under stress. Primary Objective To estimate the coronary flow reserve (CFR) (also referred to as myocardial perfusion reserve), as measured by PET stress-rest myocardial perfusion imaging, in SCD patients with and without diastolic dysfunction, and healthy controls. Secondary Objectives To investigate the relationship between decreased CFR (quantified with PET stress- rest myocardial perfusion imaging) and presence of abnormal diastolic parameters Read Less

The objective of this study is to investigate if up to two injections of plerixafor represent a safe and effective strategy to mobilize adequate numbers of CD34+ hematopoietic stem progenitor cells (HSPC) for autologous hematopoietic cell transplantation (HCT) in sickle cell disease (SCD) patients Read Less

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). Read Less

The investigators will conduct a hybrid type 1 effectiveness implementation trial to assess the effectiveness of acupuncture and guided relaxation on 360 people with Sickle Cell Disease (SCD), while observing and gathering information on implementation in three health systems: University of Illinois Hospital & Health Sciences System, University of Florida Health, and Duke University Health Systems. Each serves a large population with SCD, uses EPIC as their electronic health record, and has a Clinical and Translational Science Award (CTSA), which will help speed the translation of discovery into improved patient care. During the UH3 Implementation Phase, the 3-arm, 3-site randomized controlled trial will follow a quantitative modified SMART design, a pragmatic trial that evaluates adaptive interventions where the guided relaxation and acupuncture interventions respond to patients' characteristics and evolving pain status. The investigators rely on the Consolidated Framework for Implementation Research (CFIR) to plan, execute, and evaluate associated implementation processes. The use of complementary and integrative health (CIH) therapies by those with SCD to reduce pain and opioid use, to help enable them to better cope with their pain, is well known, but there are few studies that evaluate the effectiveness of these therapies, and none that also evaluates the implementation across multiple health care systems and patient populations as this study will. Aim 1: Determine the effectiveness of guided relaxation and acupuncture as compared to usual care in decreasing pain and opioid use for SCD patients. Hypothesis: At 6-weeks, SCD patients randomized to either CIH intervention will have a greater decrease in pain, opioid use, sleep, anxiety, depressive symptoms, and pain catastrophizing compared to SCD patients randomized to usual care. Aim 2: Identify the best adaptive intervention for improved outcomes by documenting outcomes among adaptive intervention sequences: (1) initiate guided relaxation and switch to acupuncture for non-responders at midpoint; (2) initiate guided relaxation and continue with guided relaxation for non-responders at midpoint; (3) initiate acupuncture and switch to guided relaxation for non-responders at midpoint or (4) initiate acupuncture and continue with acupuncture for non-responders at midpoint. Aim 3: Explore differences in response to the adaptive interventions by age and sex. Aim 4: Identify implementation facilitators, challenges, and solutions for structures and processes that contribute to the seamless integration of CIH therapies into the 3 health systems by conducting individual interviews with participants in the intervention group who responded to the intervention and those who did not. The investigators will also conduct focus groups with hospital personnel at 4 timepoints. Read Less

Hematopoietic stem cell (HSC)-based gene therapies now offer curative potential for patients with sickle cell disease (SCD), with decreased toxicity compared to allogeneic hematopoietic cell transplantation. However, effective HSC-based gene therapy depends on collecting sufficient HSCs to generate the therapeutic product, and currently available mobilization regimens carry unacceptable risk for patients with SCD or do not reliably yield optimal numbers of HSCs for gene therapy. The investigators hypothesize that HSC mobilization with motixafortide (CXCR4i) alone and the combination of motixafortide plus natalizumab (VLA-4i) will be safe and tolerable in SCD patients. In addition, the investigators hypothesize that combined CXCR4 and VLA-4 blockade with motixafortide plus natalizumab will result in a rapid, robust, and synergistic increase in HSC mobilization to peripheral blood (PB) in patients with SCD, when compared to motixafortide alone.

Acute vaso-occlusive crisis (VOC) is the most common complication in patients with sickle cell disease (SCD) and pain related to VOC is often inadequately treated. This is a phase II randomized controlled clinical trial evaluating the efficacy of virtual reality technology when added to standard pain management for patients with sickle cell disease who are experiencing acute pain crisis in the ambulatory care setting. Patients will be randomized to receive either standard management only or standard management in addition to virtual reality therapy. The remainder of care for the painful event will continue per institutional standards according to clinical indication, including reassessment and documentation of pain and additional doses of pain medicines by intravenous (IV) or oral route. Pain scores and opioid requirement will be measured and compared across treatment arms, along with the outcomes of discharge from clinic versus admission to the inpatient unit. PRIMARY OBJECTIVE: To assess the efficacy of virtual reality (VR) technology in reducing pain at 30 minutes after intervention during an acute vaso-occlusive crisis in patients with sickle cell disease. Primary endpoint will be change in pain scores in Standard versus VR arms, between the first pain assessment at the time of presentation and the subsequent pain assessments up to 30 minutes after intervention. Secondary Objectives: To compare total opioid consumption from the time of presentation to the time of discharge from acute care setting in Standard versus VR arms. To assess the efficacy of virtual reality (VR) technology in reducing pain at 60 minutes after the first IV medication administered or 60 minutes after completion VR during an acute vaso-occlusive crisis in patients with sickle cell disease.
