Filter by:Background: Venous thromboembolism (VTE) includes the abnormal clotting of blood in a deep vein of the upper or lower limbs (deep vein thrombosis) that may travel to and block a blood vessel in the lung (pulmonary embolism). Some people with sickle cell disease (SCD)-a red blood cell disorder-seem to be at greater risk for developing these blood clots. Researchers want to study the blood of people with SCD and VTE as well as healthy people to develop better treatments to prevent blood clots. Objective: To study blood clotting in SCD because it is the most common cause of vascular death after a heart attack or stroke. Eligibility: People ages 18-80 who have SCD (with or without a history of blood clots) or the trait for SCD, and healthy volunteers Design: Participants will be screened with medical history, physical exam, and medical records review. They will give blood samples. Participants will have phone calls either every 3 months or once a year, for 2 years. They will give updates on their health. They may give additional medical records. The phone calls may last up to 30 minutes. If participants have a VTE or pain crisis episode, they may visit the Clinical Center. These visits may last up to 4 hours. They will repeat the screening tests and give blood samples. Some participants may be invited to take part in blood studies. After 2 years, some participants will have a follow-up visit at the Clinical Center. Participation will last for about 2 years.
This study is a Phase 3, randomized, double-blind, placebo-controlled study of voxelotor in pediatric participants, aged ≥ 2 to < 15 years old, with Sickle Cell Disease. The primary objective is to evaluate the effect of voxelotor on the TCD (Transcranial Doppler Ultrasound) measurements in SCD participants in this age range.
This study aims to answer the question whether daily oral vitamin D supplementation can reduce the risk of respiratory or lung complications in children and adolescents with sickle cell disease. Respiratory problems are the leading causes of sickness and of death in sickle cell disease. The investigators hypothesize that daily oral vitamin D3, compared to monthly oral vitamin D, will rapidly increase circulating vitamin D3, and reduce the rate of respiratory complications by 50% or more within the first year of supplementation in children and adolescents with sickle cell disease. This study is funded by the FDA Office of Orphan Products Development (OOPD).
Sickle cell disease (SCD) is the most common genetic disorder in the United States affecting approximately 100,000 individuals primarily of African ancestry. Pain is the most common complication of SCD. Currently, the mainstay therapy for pain in SCD is opioids. The CDC recommends using non-opioid, non-pharmacologic therapies for pain. There is a growing body of literature to support the use of various integrative therapies for pain. Acupuncture therapy is a non-pharmacological Chinese medicine approach which has been used in many non-SCD conditions associated with pain. Proposed study will test acceptability and feasibility of use of acupuncture in SCD patients hospitalized for pain. It is hypothesized that the use of acupuncture as an adjuvant therapy will be acceptable to SCD patients admitted for pain control. Its impact on opioid use and circulating cytokines and neuropeptides will also be determined.
This is an open-label extension study of IMR-687 in adult patients who completed Imara's blinded Phase 2a study (IMR-SCD-102). The open-label extension study will evaluate long-term safety and tolerability.
Wasting is a common and significant problem in sickle cell anaemia (SCA) that correlates with poorer clinical outcome such as frequent painful crises, acute chest syndrome and sub normal resistance to infection. Thus, improvement of nutritional status in SCA holds the potential of ameliorating the course of the disease. Elevated haemolysis and its effects are associated with hypermetabolism and have resulted in higher rates of protein breakdown and synthesis, and energy expenditure. Offering more food has not optimized nutritional status and metabolic performance in free-living patients with SCA. Moreover, appetite might be suppressed. Supplementation with β-hydroxy-β-methylbutyrate (HMB), which is produced in the body from leucine, has been shown to have inhibitory effect on protein breakdown and to promote lean tissue synthesis in humans with sarcopenia. Also, HMB has been implicated as an ergogenic tool to promote exercise performance and skeletal muscle hypertrophy. Therefore, the investigators hypothesize that in individuals with SCA, an intervention of resistance exercise with HMB supplement will have a greater enhancing effect on muscle mass and strength compared to receiving resistance exercise without HMB.
The iPeer2Peer Sickle Cell Disease (SCD) study matches youth (12-18 years of age) with SCD to a mentor (trained young adult) who has learned to manage their SCD well, transitioned to adult care, and can support youth participants emotionally and socially. Participants will be randomly assigned one of two groups, either (1) The intervention group: Study group participants are matched with a mentor for 15 weeks, and are expected to have up to ten calls with one another; (2) The control group: This study group will be on a 15 week waitlist to receive a mentor. This study will first assess the feasibility of conducting this research with youth with SCD. Also, this study will assess the preliminary effectiveness of peer mentorship by comparing various health outcomes of the two study groups post-intervention.
The purpose of this study is to evaluate the Safety and Efficacy of Gene Therapy of the Sickle Cell disease by Transplantation of an Autologous CD34+ enriched cell fraction that contains CD34+ cells transduced ex vivo with the GLOBE1 lentiviral vector expressing the βAS3 globin gene (GLOBE1 βAS3 Modified Autologous CD34+ Cells) in Patients with Sickle Cell Disease (SCD)
The purpose of this study is to test the efficacy of a peer support coaching intervention to improve activated chronic illness self-management versus an attention control group in 225 adolescents and young adults with childhood onset chronic conditions.
The purpose of this study is to determine if a search strategy of searching for an HLA-matched unrelated donor for allogeneic transplantation if possible then an alternative donor if an HLA-matched unrelated donor is not available versus proceeding directly to an alternative donor transplant will result in better survival for allogeneic transplant recipients within 2 years after study enrollment.
