Filter by:This is a multi-center, open label Phase 2a clinical trial in subjects with sickle cell disease to assess safety, tolerability, pharmacokinetics, and pharmacodynamics of HBI-002, an orally administered liquid containing carbon monoxide (CO), with doses daily for 14 days.
Sickle cell disease is a painful inherited disorder that affects approximately 100,000 people in the United States, and more than half of these individuals develop chronic or persistent pain that is often severe and disabling. The factors that predict whether an individual with sickle cell disease will develop severe, disabling pain are unclear. The goal of this project is to identify the factors that predict severe pain outcomes in individuals living with sickle cell disease in order to improve pain management strategies and guide future studies of non-opioid therapies for treatment of their pain. Participants who agree to enroll in this study will be asked to participate in a virtual and then an in-person study visit for their full initial study assessment. They will answer survey questions during the virtual visit, and will be asked to complete several types of standard testing to understand how their body handles pain during the in-person visit. After completing the virtual and in-person sessions, participants will receive text or electronic medical record messages with brief survey (will take less than 8 minutes to complete) on their pain experiences every three months until the study is completed (or up to 48 months for people who are enrolled at the beginning of the study).
A prospective, single-arm, intervention study of oral alendronate in adults with sickle cell disease and osteonecrosis
Primary aim to determine the effects of immersive VR on pain management in children with SCD. Secondary aim to determine the effects of immersive VR in musculoskeletal dysfunction in children with SCD and health-related quality of life.
The purpose of the study is to evaluate the efficacy and safety of CTX001 (exa-cel) in adolescent and adult participants with severe sickle cell disease (SCD), βS/βC genotype (HbSC).
Background: Sickle cell disease (SCD) is a genetic disease that causes the body to produce abnormal ( sickled ) red blood cells. SCD can cause anemia and life-threatening complications in the lungs, heart, kidney, and nerves. People with SCD are also at increased risk of forming blood clots in the veins and lungs, but the standard treatments for these clots can cause increased bleeding in people with SCD. Better treatments are needed. Objective: To test a drug (fostamatinib) in people with SCD. Eligibility: People aged 18 to 65 with SCD. Design: Participants will have 6 clinic visits over 12 weeks. Each visit will be 2 to 3 hours. Participants will be screened. They will have a physical exam with blood tests. They will tell the researchers about the medications they take. Fostamatinib is a tablet taken by mouth. Participants will take the drug at home, twice a day, for up to 6 weeks. Participants will have a clinic visit every 2 weeks while they are taking the drug. At each visit they will have a physical exam with blood tests. They will talk about any side effects the drug may be causing. If they are tolerating the drug well after the first 2 weeks, they may begin taking a higher dose. Participants will have a final visit 4 weeks after they stop taking the drug. They will have a physical exam and blood tests; they will be checked for any side effects of the drug.
1. To study the expression pattern of PUM1 gene in patients with sickle cell anemia and β-thalassemia intermedia. 2. To detect PUM1 protein levels in sickle cell anemia and β-thalassemia intermedia patients. 3. To correlate PUM1 gene expression pattern and protein levels with HbF levels in sickle cell anemia and β-thalassemia intermedia patients.
This study is aimed to assess the genetic and haematological modifiers of disease severity among patients with Sickle Cell Disease (SCD) in Kaduna State, northern Nigeria. It is composed by two separate study designs: a cross-sectional study and a longitudinal study. The cross-sectional study will evaluate clinical and laboratory parameters in paediatric Sickle Cell Anaemia (SCA) patients (ages 2-18 years) in steady state and during Vaso-Occlusive Crisis (VOCs) to determine the parameters that can be used as a guide to monitor the course of the disease towards early recognition and management of sickle cell crises. In addition, the study will explore genotype-phenotype correlations in SCA patients by targeted Next-Generation Sequencing (NGS) of genetic modifiers for haemoglobinopathies. The longitudinal study will collect clinical and laboratory data over time for a paediatric cohort of SCD patients (9 months old; followed up to 2 years of age) and parental samples will be collected to determine the βS-globin haplotype in family trios. The aim is to determine the temporal relationships among foetal haemoglobin (HbF) levels, haematological parameters and frequency of sickle cell crises in SCD patients in relation to the type of the βS-globin haplotype and the sickle genotype. In addition, samples collected at 24 months of age will also be analysed by NGS to identify genetic modifiers of clinical manifestations and severity of SCA. Participants from the following centre will be involved: Ahmadu Bello University Teaching Hospital (ABUTH) Zaria. Consent from all the study parents/legally designated representatives as well as assent from minors will be sought. Consent for genetic analyses will be sought as well. Clinical and haematological analyses will be performed at ABUTH while genetic analyses will be performed at the Cyprus Institute of Neurology and Genetics (CING).
This project assesses feasibility of providing medically vulnerable rural patients with Medical-Self-Assessment-Boxes containing equipment to use at home during telephone and video consultations (telemedicine) with GPs and other healthcare professionals. COVID-19 has caused an upsurge in primary care telemedicine which the investigators believe can be sustained and optimized to make things better for medically vulnerable rural patients beyond the pandemic. The investigators will achieve this by equipping the participants to self-measure and report key clinical measurements (e.g. blood pressure, temperature, oxygen levels) during telemedicine consultations. Before conducting a major evaluation of the Medical-Self-Assessment-Box for medically vulnerable rural patients the investigators must establish three things: First, to show the investigators can issue a Medical-Self-Assessment-Box to medically vulnerable rural patients and enable them to use it properly. Second, to determine that patients can use the Medical-Self-Assessment-Box effectively during telemedicine consultations. Third, to show that it is possible to measure how well the Medical-Self-Assessment-Box is working by counting how often the boxes are being used and whether use is appropriate and helpful. The knowledge gained will provide the investigators with the information needed to develop a funding proposal to evaluate Medical-Self-Assessment-Boxes for medically vulnerable rural patients in the whole of the UK.
