31 Clinical Trials for Various Conditions
Sickle cell disease (SCD), specifically hemoglobin SC disease (HbSC), is a subtype of sickle cell disease with typically higher hemoglobin and milder or later disease complications. Sickle cell disease is a disorder in which red blood cells (RBCs) are abnormally shaped. This can result in painful episodes, serious infections, and damage to body organs. One medication used to treat sickle cell disease is hydroxyurea. Hydroxyurea therapy offers significant benefits for infants, children, and adolescents with sickle cell anemia. These include a reduction in the frequency of pain crises and acute chest syndrome (inflammation of the lungs). Hydroxyurea has been given to many HbSC patients but HbSC patients were not included in the large clinical trials used to test hydroxyurea in SCD, so less is known about how HbSC patients respond to hydroxyurea. The purpose of this research study is to see if hydroxyurea, a medication given to many patients with the most common type of sickle cell, those who are homozygous for the sickle mutation (HbSS), helps individuals who have HbSC. The investigators will see if it helps by giving a questionaire when the medication is started, and then every two months at a clinic visit. The questionaire, called the AdultsQLTM 3.0 Sickle Cell Disease Module, measures quality of life. The investigators will also see how hydroxyurea changes laboratory test numbers, and blood thickness.

Subjects have a form of sickle cell disease, called hemoglobin SC disease. This results in abnormally shaped red blood cells that get 'stuck' in blood vessels and then results in episodes of severe pain (pain crises). Patients with the more common form of sickle cell disease, called hemoglobin SS disease, also suffer from pain crises. Treatment with the drug hydroxyurea is available to help prevent the pain crises in hemoglobin SS disease, but there is no good treatment to help prevent the pain crises in hemoglobin SC disease. It has been shown that one of the reasons for the formation of the abnormally shaped red blood cells in patients with SC disease is the fact that these cells do not contain enough water; they are dehydrated. Drinking more water will not increase the amount of water in the cells. Certain salts and minerals can however have an effect on the amount of water in the red blood cells. One of the most important minerals influencing this is called magnesium. Magnesium is present in food and also in certain medications used to treat heartburn. Magnesium has been used successfully both in animals and people to increase the amount of water in the red blood cells and is very well tolerated by most people. Investigators are using a new form of magnesium known as magnesium pidolate because this form of magnesium may help with the symptoms of disease without causing diarrhea (a common side effect of magnesium products). Purpose The purpose of this study is to find out whether treatment with magnesium pidolate will increase the amount of water in the red blood cell and result in fewer painful crises in patients with hemoglobin SC disease while not causing diarrhea. The study will last for about 64 weeks (about 16 months).
Children with sickle cell disease (SCD) are at risk for central nervous system (CNS) complications, which may affect academic achievement. This study will evaluate an educational support program for parents that aims to improve academic achievement in children with SCD.
Sickle cell disease (SCD), also known as sickle cell anemia, is an inherited blood disease that can cause intense pain episodes. Hemoglobin SCD (HbSC) is a form of SCD that is characterized by dense red blood cells. The purpose of this study is to evaluate the safety and effectiveness of hydroxyurea and magnesium pidolate, alone and combined, at reducing red blood cell density and the frequency of pain episodes in people with HbSC.
Sickle cell anemia is a genetic disorder that results from a single nucleotide substitution in codon 6 of the beta-globin gene which, in the homozygous state, produces an abnormal hemoglobin that is prone to polymer formation when deoxygenated. The polymerized hemoglobin leads to impaired deformability and sickling of red blood cells which subsequently lodge in end-arterioles producing the classic and most prominent feature of the disorder, repeated vasoocclusive crises. Despite knowledge of the precise genetic defect for decades, only recently has there been therapeutic impact based upon this knowledge when a clear benefit from treatment with hydroxyurea, a cell cycle-specific agent administered to induce production of fetal hemoglobin (HbF) by stimulating gamma-globin synthesis, was reported in patients with sickle cell disease (SCD). The reduction in the frequency and severity of vasoocclusive crises seen has been attributed to the increase in HbF levels in responsive patients. While the majority of patients demonstrate a rise in HbF, not all such patients benefit from treatment. Given these results, alternative agents that also stimulate the production of HbF warrant investigation in the treatment of SCD. Recombinant-methionyl human stem cell factor (SCF) is a hematopoietic growth factor with activity on immature hematopoietic progenitor cells. SCF stimulates the production of HbF in vitro and in vivo, and this effect is attainable without the myelosuppression associated with hydroxyurea. In this phase I/II trial, we will administer SCF in a dose escalating fashion to patients with sickling disorders. Parameters to be measured are HbF levels, F cell levels, peripheral blood CD34 levels, frequency, duration, and severity of vasoocclusive crises, and toxicity.
Sickle cell disease (SCD) is an inherited disorder with chronic multi-system manifestations affecting 100,000 individuals in the US, largely of minority origin and associated with substantial morbidity, premature mortality, individual suffering, healthcare costs and loss of productivity. Disease modifying treatments such as hydroxyurea, chronic blood transfusion and curative bone marrow transplantation are offered to patients based on physician preference and current practice informed by clinical trials. Decision aids are tools that could help translate evidence from these sources into practice by helping clinicians involve patients in making deliberate choices based on accessible information about the options available and their outcomes and to help them make decisions based on their values and preferences. The overarching goal of this project is to implement a web based decision aid individualized to patient characteristics to help patients with SCD achieve more accurate perception of risks and benefits of treatment options and make decisions in congruence with their values and preferences. Investigators will use a randomized controlled trial of the effectiveness of a web-based decision aid to give patients accurate information about risks and benefits of therapies that enable patients to make decisions based on their individual values and preferences.
Sickle cell disease (SCD) is a blood disorder that is characterized by intense, painful episodes known as sickle cell crises. This study will evaluate the effectiveness of PAINRelieveIt, a three-part computer-based pain management tool, in treating adults with SCD.
Patients are being asked to participate in this study because they have severe sickle cell anemia (SCD) with or without the beta thalassemia trait. Sickle cell anemia is an illness where the red blood cells change shape and can clog up blood vessels. This keeps the body from getting the oxygen it needs. Thalassemia is when the body does not make enough hemoglobin, something that helps the oxygen get to the places it needs to go in the body. The patient may or may not need to get regular blood transfusions (getting more blood) to improve their quality of life (feel better) and prevent organ damage (problems with the brain, heart, lung, kidney, and gonad, for example.). The transfusions can also cause problems, including iron overload (too much iron in the blood), which can be fatal (patients can die) without regular deferoxamine shots. Even with the best usual treatments, people with thalassemia or SCD die sooner. There is no proven cure. We would like to treat patients using bone marrow transplantation, a treatment that has been used for people with SCD. The transplant uses healthy "matched" bone marrow. This comes from a brother or sister who does not have sickle cell disease or severe thalassemia. If the treatment works, the sickle cell disease or thalassemia may be cured. This treatment has been used to treat patients with sickle cell disease or thalassemia. It has worked in most cases. We hope, but cannot promise, that the transplanted marrow will make healthy cells, and patients will not have sickle cell disease or severe thalassemia anymore. We do not know what effect this treatment will have on the damage that has already been done by the disease. Finding that out is the main reason for this study. Currently, very little has been reported about organ function after bone marrow transplants in patients with sickle cell anemia.
The purpose of this study is to find out if using a lower dose of chemotherapy before stem cell transplantation can cure patients of sickle cell anemia or thalassemia while causing fewer severe side effects than conventional high dose chemotherapy with transplantation.
The primary objectives of this prospective mixed-method interview study are to use semi-structured interviews in parents of sickle cell disease (SCD) patients to describe parental attitudes of research involving genomic sequencing, including concerns about participation and expectations from researchers and to use surveys to quantitatively measure genetic/genomic knowledge, trust in health care provider, and literacy/numeracy ability in parents of children with SCD and adolescents with SCD. Investigators hope to use the results of the planned surveys and interviews to reduce the risk of misunderstanding about DNA and genetic research and build strong relationships between SCD families and researchers in the future, and to design educational information and study materials that will help parents with children with SCD understand important details about DNA and genetic research.
The purpose of the CSEG101A2202 study was to characterize the Pharmacokinetic (PK) and Pharmacodynamic (PD) of SEG101/crizanlizumab and to evaluate the safety and efficacy of SEG101/crizanlizumab in sickle cell disease (SCD) patients.
Clinical study to determine if there is a difference in hemoglobin level between patients undergoing total knee arthroplasty with and without platelet-rich plasma.
Sickle cell disease is a life-threatening genetic disorder that can be effectively treated following early diagnosis via newborn screening. However, sickle cell disease is most prevalent in low-resource regions of the world, where newborn screening is rare due to the cost and logistical burden of laboratory-based methods. In many such regions, \>80% of affected children die, undiagnosed, before the age of five years. A convenient and inexpensive point-of-care test for sickle cell disease is thus crucially needed. In this study we will conduct a blinded, multicenter, prospective diagnostic accuracy study of HemoTypeSC(TM), an inexpensive 15-minute point-of-care immunoassay for detecting sickle cell disease, hemoglobin C disease, and trait phenotypes in newborns, children, and adults.
The purpose of this clinical trial is to evaluate the performance of the sickle cell disease (SCD) electronic diary in people with SCD who are on treatment that will change SCD and those not on such a treatment. SCD is a type of condition when there are fewer red blood cells to carry oxygen around the body. This disease can be passed on from parent to child and may cause pain, infections and damage to organs. This study is seeking participants who: * are confirmed with SCD * are on a stable regimen of disease changing treatment or have not received any disease changing treatment before the start of the study and do not plan any changes in their treatment during the 6-month study observation period For 6 months, participants will be asked to complete a daily electronic diary to report on their experience in the past 24 hours with sickle cell pain crisis (if they got any treatment and what medications they took), worst pain, worst tiredness, and their ability to perform usual physical activities. We will compare the experiences of people who are taking SCD-modifying therapy to those that are not taking a SCD-modifying therapy.
The primary objective of this study is to better understand factors contributing to variations in hydroxyurea (HU) adherence behavior in adolescents and young adults (AYA) with sickle cell disease (SCD). To meet this objective, the researchers will conduct a prospective cohort study to determine the longitudinal relationship between HU adherence and health-related quality of life (HRQOL) overtime among AYA with SCD. The long-term goal of this research is to promote medication adherence behavior and improve health outcomes in AYA with SCD.
The overarching goal of this proposal is to identify modifiable behavioral strategies based on patient-reported outcomes (PROs) and health-related quality of life (HRQOL) that will improve hydroxyurea (HU) adherence among adolescents and young adults with sickle cell disease (SCD). In this proposed study, we intend to test the functionality of a PROs-toolbox feature, which will be integrated into our existing smartphone application platform (SCD-app), over a 24-week period in a cohort of SCD patients and their caregivers.
This is an observational study in which patients who have been prescribed Néevo®/NéevoDHA® are invited to participate in surveys about their pregnancy and experiences with Néevo®/NéevoDHA®. The purpose of this study is to increase the understanding of the role of L-methylfolate among patients who are candidates for Néevo®/NéevoDHA®, provide patients with personalized education and support during their pregnancies, and contribute to the overall understanding of the needs and concerns of women facing intermediate- to high-risk pregnancies.
The purpose of the study is to determine the effectiveness of LOVAZA (fish oil capsules) to decrease inflammation in children and adolescents with Sickle Cell Disease (SCD). It has been found that besides the damage caused by sickle red blood cells themselves, the inflammatory response that occurs in SCD patients could potentially play a significant role in the occurrence of painful episodes or pain crises. The investigators will also study whether the subject/caregiver feels that there is an improvement in the child's quality of life by taking the medication. Besides the effect of LOVAZA on inflammation,the investigators are also testing whether the drug will have a beneficial effect on blood clotting ability (which is known to be increased in SCD) and on the anemia (low red blood cells) that is part of the disease entity.
The purpose of this study is to compare the efficacy and safety of 2 doses of crizanlizumab (5.0 mg/kg and 7.5 mg/kg) versus placebo in adolescent and adult sickle cell disease (SCD) patients with history of vaso-occlusive crisis (VOC) leading to healthcare visit.
This is a clinical research trial in which a novel preparatory regimen was developed for bone marrow transplant (BMT) which eliminates the primary obstacle to transplant, the lack of a matched sibling donor. It is believed this regimen is sufficiently efficacious and sufficiently gentle to apply to patients with sickle cell anemia and related disorders. It is proposed to characterize the efficacy and toxicity of this regimen in high risk patients with sickle cell anemia using criteria for patient selection that have been accepted in prior BMT trials in patients with sickle cell disease, specifically only the subset of patients whose prior clinical behavior indicates that they are at high risk for serious morbidity and early mortality. In addition, it is proposed to characterize the pathophysiology of a consistent febrile response seen in the haploidentical BMT regimen the investigators have developed at Thomas Jefferson University (TJU). The primary goal of this study is to determine the response rate to a reduced intensity conditioning regimen which consists of fludarabine, cytarabine, low dose total body irradiation and cyclophosphamide in patients with severe sickle cell anemia.
This study is designed to see if abdominal ultrasound after planned cesarean delivery can identify women with ongoing intra-abdominal bleeding.
A phase III, multi-center, randomized, placebo-controlled, double-blind study to assess efficacy and safety of crizanlizumab (5 mg/kg) versus placebo, with or without hydroxyurea/hydroxycarbamide therapy, in adolescent and adult Sickle Cell Disease patients with frequent vaso-occlusive crises.
The purpose of this study is to find out whether siplizumab is safe and effective for patients with SCD undergoing an allogeneic transplant and to prevent development of Graft versus Host Disease (GVHD) and graft failure. The main goals of this study are : * To determine if acute GVHD occurs and how severe the acute GVHD is in subjects receiving the study drug * To determine if graft failure occurs in subjects receiving the study drugs In this study, participants will receive 5 infusions of the study drug, siplizumab, while getting a stem cell transplant for SCD. Before siplizumab infusion, participants will be given medications to reduce the risks of allergic reaction to the drug.
This study is an open-label study to evaluate the safety of long-term administration of inclacumab in participants with sickle cell disease (SCD). Participants in this study will have completed a prior study of inclacumab.
This clinical trial is a Phase 2 study that will evaluate the safety and clinical activity of etavopivat in patients with thalassemia or sickle cell disease and test how well etavopivat works to lower the number of red blood cell transfusions required and increase hemoglobin.
This Phase 3 study will assess the safety and efficacy of inclacumab, a P-selectin inhibitor, in reducing the frequency of vaso-occlusive crises (VOCs) in approximately 240 adult and adolescent participants (≥ 12 years of age) with sickle cell disease (SCD). Participants will be randomized to receive inclacumab or placebo.
This Phase 3 study will assess the safety and efficacy of a single dose of inclacumab, a P-selectin inhibitor, for a vaso-occlusive crisis (VOC) after an index VOC in participants with sickle cell disease (SCD). Participants will be randomized to receive either inclacumab or placebo.
The Beaumont Hospital Royal Oak Outpatient Clinic (and other listed Beaumont recruiting locations) care for over 900 patients with diabetes. In an effort to improve the care provided to our patients, a pharmacist managed diabetes clinic (PMDC) was created. The investigators looked at patients with high-risk diabetes who have received education in the PMDC and compared them to patients that didn't not receive the pharmacy education. Our preliminary data showed a significant decrease in Hemoglobin A1c in the PMDC compared to our standard care cohort. Hemoglobin A1c is a marker of the severity of diabetes mellitus. Based on this data, we designed a randomized controlled trial to better assess the impact of a PMDC on diabetic outcomes.
This study will collect representative blood samples from healthy children and adults and from children and adults who have unique red blood cell features that are related to sickle cell disease. Sickle cell disease is a blood disease that limits the ability of red blood cells to carry oxygen throughout the body. The purpose of the study is to collect a variety of blood samples that may then be used to investigate advances and potential new drug treatments for sickle cell disease. Volunteers must be at least 18 years of old. Samples will be taken both from healthy volunteers and from volunteers who have unique red blood cell features that are related to sickle cell disease. Candidates will be screened with a medical history. During the study, participants will undergo a one- to two-hour outpatient procedure at the National Institutes of Health Clinical Center. Once researchers have explained the study and obtained the participant s consent, participants will donate 8 cc (approximately 2 teaspoons) of blood. Because repeat testing helps researchers validate study findings, participants who have the unique red blood cell features mentioned above may also be asked if they are willing to return and donate another 2 cc to 8 cc of blood for additional studies. The amount of blood drawn will not exceed 50 ml with any eight-week period for adults or 7 cc within any six-week period for children.
