Filter by:The purpose of this study is to assess the safety and tolerability of HQK-1001 administered for a total of 12 weeks (with one dosing break) in subjects with sickle cell disease.
This study will evaluate the safety of eptifibatide in sickle cell patients and how well it works during the course of painful crises. The overall hypothesis that we seek to test is that increased platelet activation and the resultant inflammatory responses are important contributors to the problems of sickle cell disease. Sickle cell disease has been referred to both as a condition associated with increased risk of blood clots and increased inflammation. A painful crisis represents the most common cli nical problem in sickle cell disease, but the treatment of these crises remains inadequate.
The purpose of this study is to validate a brief survey tool, the SCD Pain Burden Interview (SCPBI), which can be used in the clinical and/or research settings to assess the impact of pain on children with sickle cell disease.
In sickle cell disease (SCD), polymerisation of haemoglobin S and the resulting shape change of the red blood cells (RBC) lead to vascular occlusion and severe painful crises. Permanent inflammatory state and abnormal RBC adhesion to the endothelium trigger these phenomenon. Hydroxyurea (HU) is the only drug that has been shown to reduce clinical severity of SCD, and this was initially attributed to the stimulation of foetal haemoglobin (HbF). However, the clinical response does not correlate consistently with the degree and time of HbF increment, suggesting that HU clinical benefits may involve other mechanisms such as the induction of natural anti-inflammatory response via the hypothalami-pituitary-adrenal axis.
The goal of this research study is to establish chimerism and avoid graft-versus-host disease in patients with Hemoglobinopathies to halt disease progression.
This study is designed to assess the safety, tolerability, and activity of TRF-1101 on microvascular blood flow, vascular endothelial injury, and vasoocclusive pain associated with sickle cell disease.
To determine the pharmacokinetics of methadone in children and adults with SCD who are experiencing a painful episode.
This purpose of this study is to understand the differences between people who have a good response to deferasirox (exjade) compared to people who have a poor response to this medication when used for transfusion-dependent iron overload. The hypothesis is that patients with poor responses have physiologic barriers to deferasirox that may include absorption, pharmacokinetics of drug metabolism, hepatic clearance and/or genetic factors.
Acute chest syndrome (ACS) is a frequent and potentially life-threatening pulmonary illness. It is a complication of sickle cell disease and is the leading cause of death from this disease in adults. Several pathologic processes are recognized causes of ACS, including infectious diseases, hypoventilation secondary to chest pain, in situ thrombosis and pulmonary fat embolism. Inhaled nitric oxide (iNO) has been shown to be a pulmonary vasodilatator with minimal systemic effects and has also been shown to improve gas exchange in both animal and human acute lung injury (ALI). The combined effects of iNO gas of improving pulmonary ventilation to perfusion matching, reducing alveolar and systemic inflammation, modulate the course of acute chest syndrome, which combine the physiopathology of vaso-occlusive crisis and acute lung injury. We hypothesise inhaled NO will improve oxygenation and clinical outcome of sickle cell disease patients with acute chest syndrome.
Sickle cell disease (SCD), also known as sickle cell anemia, is an inherited blood disease that can cause organ damage, stroke, and intense pain episodes. A blood stem cell transplant is a treatment option for someone with a severe form of the disease. Prior to undergoing a transplant, people typically receive a conditioning regimen of high doses of chemotherapy and other medications to prepare the body to accept the transplant. A conditioning regimen that uses lower doses of chemotherapy and medications may be safer for transplant recipients. This study will evaluate the safety and effectiveness of blood stem cell transplants, using bone marrow from unrelated donors, in children with severe SCD who receive a reduced intensity conditioning regimen prior to the transplant.
