This study will investigate the role of genetic modifiers in hemoglobinopathies through a large-scale, multi-ethnic genome-wide association study (GWAS).
Background:
People with sickle cell disease (SCD) have problems with their heart, brain, kidneys, liver, and lungs as they age. These problems may improve after transplant. Researchers want to learn how and why this happens.
Objective:
To study the benefits of treatments that are intended to cure SCD.
Eligibility:
People aged 18 and older with SCD who are either receiving curative therapy in the next 3 months or don t have any plans to receive a curative therapy in the next 2 years.
Design:
The goal of this study is to evaluate if patients with sickle cell disease can achieve a maximum tolerate dose of hydroxuyrea (HU) over a period of 12 months faster with pharmacokinetic testing than the standard of care bloodwork follow-up. Pharmacokinetic test is used to evaluate the process by which drugs are absorbed, distributed in the body, localized in the tissues, and is excreted.
The objective of this study is to evaluate the incidence of ACS within the DREPADOM system and compare it to expected incidences of ACS (historic cohorts of PRESEV1 and PRESEV2)
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 evaluate crovalimab for the treatment of a sickle cell pain crisis (also known as a VOE) that requires hospitalisation in adult and adolescent participants with SCD. The primary objective of this study is safety and will additionally evaluate pharmacokinetics (how crovalimab is processed by your body), pharmacodynamics (how your body reacts to crovalimab) and the preliminary efficacy of crovalimab compared with placebo.
This study will determine whether niacin can improve blood flow in people with sickle cell disease, in which abnormal red blood cells interfere with blood flow to cause the disease symptoms. Niacin, a drug that has been used to increase HDL (good cholesterol) levels, improves blood flow in people without sickle cell disease. This study will see if it can do the same in people with the disease.
Patients with sickle cell disease between 18 and 65 years of age may be eligible for this study.
ICA-17043 is being developed for the chronic treatment of patients with sickle cell disease (SCD) in both adults and children. ICA-17043 is a potent and specific inhibitor of a channel in human red blood cells (RBCs) that blocks RBC dehydration. ICA-17043 is expected to inhibit RBC dehydration and thus should prevent or delay the sickling process. By reducing sickled cells, an improvement in anemia, a reduction in painful crises, and ultimately, less end-organ disease is anticipated.
Background:
\- Small blood vessels (microvessels) in many different organs are affected by diseases such as diabetes and atherosclerosis. These microvessels may also be abnormal in people who have sickle cell disease. Stiffness of the red blood cells leads to problems in the microvessels of the heart and kidneys. However, these problems may not be detected until these organs are severely affected. Researchers want to study problems with microvessels in people with and without sickle cell disease.
Objectives:
The aim of this study is to collect and analyze retrospective data on Oxbryta in a real-world setting. This is a multicenter, retrospective data collection and analysis study to characterize health outcomes in approximately 300 patients with SCD who have been treated with Oxbryta as part of their usual care. Any patient with SCD who received Oxbryta treatment for at least 2 weeks as part of their usual care according to the Oxbryta US Prescribing Information (USPI) is eligible to participate.
