66 Clinical Trials for Various Conditions
The purpose of this pilot study is to evaluate the feasibility of using Ferumoxytol as a contrast agent on a low field strength, portable magnetic resonance imaging (MRI) system. Participants receiving Ferumoxytol as part of routine clinical care for iron deficiency anemia will be recruited and scanned on the Hyperfine MRI system before and after their clinically scheduled intravenous infusion. Resultant images will be compared to assess signal intensity changes generated by the presence of Feromoxytol.
OBJECTIVES: I. Determine the response rate and 1-year event-free survival in patients with severe autoimmune hematologic disease treated with high-dose cyclophosphamide.
Background: Pyrimidine and purine metabolism disorders (DPPMs) affect how the body metabolizes chemicals called pyrimidines and purines. DPPMs can cause dysfunctions throughout the body, especially in the brain, blood, kidneys, and immune system. People with DPPMs might have no symptoms, mild symptoms, or they may have severe, chronic symptoms, that can be fatal. DPPMs are not well understood, and researchers want to learn more about what causes them and how to treat them. Objective: To learn more about factors that affect DPPMs by comparing test results from affected, uaffected family members, and healthy people. Eligibility: Three types of participants are needed: people aged 1 month and older with DPPMs; their family members who do not have DPPMs; and healthy volunteers. Design: Participants with DPPMs will come to the clinic once a year; some may be asked to come more often. At each visit, all affected participants will have a physical exam and give samples of blood, urine, saliva, and stool. Depending on their symptoms, they may also have other procedures, such as: Swabs of their skin and inside the mouth. Tests of their heart, kidney, brain, and nerve function. Questionnaires about what they eat. Dental exams, and exams of their hearing and vision. Tests of their learning ability. Monitoring of their physical activity. Imaging scans. Photographs of their face and body. These tests may be spread over up to 7 days. Affected participants may remain in the study indefinitely if they wish to. Healthy volunteers and family members will have 1 study visit. They will have a physical exam and may be asked to give blood, urine, saliva, and stool samples.
The primary objective of this study is to understand and characterize the health-related quality of life (HRQoL) and disease burden of adult participants with PK deficiency receiving routine clinical care. This study is an observational (i.e., noninterventional), longitudinal, multicenter, global registry for participants with PK deficiency, a rare nonspherocytic hemolytic anemia. This study will be open for enrollment for 2 years and all enrolled participants will be followed prospectively for up to 96 weeks. Data will be collected from participants who have provided informed consent and authorization pursuant to applicable laws and regulations.
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).
Study AG348-C-007 was a multicenter study designed to evaluate the efficacy and safety of treatment with AG-348 in a minimum of 20, with up to 40, participants with pyruvate kinase (PK) deficiency, who were regularly receiving blood transfusions. The study was composed of two parts. During Part 1, Dose Optimization Period, participants started on a dose of 5 mg AG-348 administered twice daily. Over the course of Part 1 each participant's dose of AG-348 was sequentially increased to 20 mg twice a day, followed by 50 mg twice a day depending on their tolerance. During Part 2, Fixed-Dose Period, participants received AG-348 at their optimized dose from Part 1.
Study AG348-C-006 evaluated the efficacy and safety of orally administered AG-348 as compared with placebo in participants with pyruvate kinase (PK) deficiency, who were not regularly receiving blood transfusions. Participants were randomized 1:1 to receive either AG-348 or a matching placebo.
In this study, the investigators test 2 dose levels of thiotepa (5 mg/kg and 10 mg/kg) added to the backbone of targeted reduced dose IV busulfan, fludarabine and rabbit anti-thymocyte globulin (rATG) to determine the minimum effective dose required for reliable engraftment for subjects undergoing hematopoietic stem cell transplantation for non-malignant disease.
The overall goal of the project is to reduce pain-related, 30-day readmission rates for sickle cell disease (SCD) patients. The investigators want to see if a mobile phone application (app) can help decrease the need for repeat admission to the hospital because of sickle cell pain.
Treatment for patients with autoimmune destruction of blood cells is poor. The part of the body that fights infections is called the immune system and white blood cells (WBCs) are part of the immune system. Normally, a person's body creates WBCs to fight infections and eliminates WBCs which have stopped helping the body function. Patients with autoimmune destruction of blood cells have difficulty eliminating old WBCs. The abnormal WBCs build up and can damage other healthy cells, which can lead to anemia, fatigue, jaundice, internal bleeding, infection, and cancer. Few effective medications exist for treatment for patients with autoimmune cytopenias and those commonly used are fraught with side effects. Nevertheless, as scientific understanding of autoimmune diseases has improved, more directed and less toxic therapies are becoming available. A number of groups have been studying the efficacy of a medication called sirolimus in patients with autoimmune diseases. This medicine has been FDA-approved for over 20 years. Sirolimus is a medicine used in children with other diseases. Sirolimus works, in part, by eliminating old and abnormal WBCs. Our group and others have shown that sirolimus is effective in mice with autoimmunity and in children with a rare condition called Autoimmune Lymphoproliferative Syndrome (ALPS). We believe sirolimus will help children with autoimmune cytopenias. We believe it will improve their symptoms and make them less sick. We propose to study sirolimus in children with chronic and/or refractory autoimmune cytopenias.
OBJECTIVES: I. Determine whether there is prompt engraftment after autologous peripheral blood stem cell transplantation using filgrastim (G-CSF) mobilization in patients with life threatening autoimmune diseases. II. Determine the kinetics of T- and B-cell immune reconstitution after a combination of timed plasmapheresis, high dose cyclophosphamide and total lymphoid irradiation, and posttransplant immunosuppression with cyclosporine in these patients. III. Determine whether this treatment regimen beneficially influences the clinical course of these patients.
