Filter by:A single-arm study utilizing a 6 x 4 expansion design using daratumumab SC treatment for patients with refractory Autoimmune Hemolytic Anemia.
Background: Sickle cell disease (SCD) is a disorder that causes episodes of acute pain and progressive organ damage. Ways to manage SCD have evolved slowly. Treatments do not always work. Researchers want to see if a drug called mitapivat can help people with SCD. Objective: To test the long-term tolerability and safety of mitapivat (or AG-348) in people with SCD. Eligibility: Adults age 18-70 with SCD who took part in and benefited from NIH study #19H0097. Design: Participants will be screened with a medical history and physical exam. They will give a blood sample. They will have an electrocardiogram to test heart function. Participants will repeat some of the screening tests during the study. Participants will complete 6-minute walk tests to measure mobility and function. They will have transthoracic echocardiograms to measure heart and lung function. They will have dual-energy X-ray absorptiometry scans to measure bone health. They will complete online questionnaires that measure their overall health and well-being. Participants will take the study drug in the form of a tablet twice a day. Participants will keep a study diary. They will record any symptoms they may have. Participation will last for about 54 weeks. After 48 weeks, participants can either keep taking the study drug for 48 more weeks or be tapered off of the study drug to complete the study. Those who are on the study for 1 year will have 10 study visits. Those who are on the study for 2 years will have 14 study visits.
The aim of this study is to evaluate development of hemolysis and the variation in isokinetic muscle strength in two groups of patients with chronic inflammatory demyelinating polyneuropathy (CIDP) or multifocal motor neuropathy (MMN) 1. Patients shifted from 3- or 6-weekly treatment with intravenous immunoglobulin (IVIG) to weekly treatment with subcutanoeus immunoglobulin (SCIG) 2. Patients shifted from SCIG treatment with Subcuvia® or Hizentra® to Gammanorm®. Hypotheses - During treatment with IVIG blood hemoglobin will fluctuate with a decline due to infusion, whereas it will remain stable during SCIG treatment without fluctuation - Isokinetic muscle strength in affected muscle groups is more stable during treatment with SCIG than with IVIG - Blood hemoglobin and changes in muscle strength is comparable during Subcuvia® or Hizentra® and Gammanorm® treatment
The study intends to summarize the clinical and laboratory characteristics of children with hemolytic anemia diagnosed as having alpha thalassemia mutations.
In this prospective observational trial, participants with chronic hemolysis will be assessed with echocardiogram for elevated tricuspid jet velocity and other evidence of pulmonary hypertension. Participants will have laboratory studies evaluating: severity of hemolysis, splenic function, inflammation, endothelial dysfunction, and hypercoagulability. There will be 3 main categories of participants enrolled in this study: (1) pediatric participants with severe sickle cell disease (SCD) (HbSS, HbS/β° thalassemia ) who are not receiving treatment (e.g., hydroxyurea or chronic transfusions); (2) pediatric participants with other forms of SCD or severe SCD (HbSS, HbS/β° thalassemia) patients being treated with hydroxyurea or chronic transfusions; and (3) pediatric and adult participants with other non-sickling hematological disorders.
This study will examine the long-term safety and efficacy of Deferasirox in patients with sickle cell disease and iron overload from repeated blood transfusions.
Hepatitis C is a major cause of liver disease in the United States and leads to cirrhosis of the liver in approximately one-third of patients some of whom will ultimately suffer from liver failure or liver cancer. At present, the recommended therapy of hepatitis C is the combination of alpha interferon and ribavirin given for 6 to 12 months. Ribavirin is a antiviral drug that is given by mouth. Interferon is both an antiviral and an immune medication which must be given by injections (three times a week) and has many difficult side effects. The purpose of this study is to determine whether the combination of ribavirin and interferon improve the liver disease of hepatitis C and whether improvements can be maintained by continuing ribavirin therapy long-term. This study will take 100 to 120 patients suffering from hepatitis C and place them under combination drug therapy with alpha interferon and ribavirin. The course of drug therapy is scheduled to last 6 to 12 months. Patients will be selected after appropriate screening for hepatitis C virus and elevated liver enzymes are conducted and liver biopsy shows chronic hepatitis with some degree of injury and scarring. During the first 6 months of the study, subjects will be asked to return to the outpatient clinic for routine check-ups and blood tests every 2 to 4 weeks. Blood tests will include tests for hepatitis C virus. If the virus test becomes negative on treatment, the therapy will be considered successful and will be continued for a full 6 or 12 months (depending upon the strain of virus). If the virus test does not become negative during the first six months of treatment, subjects will be considered "non-responders" and will stop taking interferon but will continue on ribavirin alone or an identically appearing placebo tablet. These non-responsive subjects will continue this therapy for an additional 12 months. (A year-and-a-half total). Upon completion of the drug therapies, subjects will be requested to submit blood samples and undergo a liver biopsy to determine if the therapy was successful. Test results that reveal a loss of hepatitis C antibodies or normal levels of liver enzymes will be deemed successful. Patients that have successful laboratory test results will be considered for continuation of ribavirin therapy. Patients that received placebo for a year will be eligible to receive ribavirin long-term at the end of the study.
