Active clinical trials for "Anemia, Hemolytic"

The purpose of this study is to evaluate whether fostamatinib is safe and effective in the treatment of Warm Antibody Autoimmune Hemolytic Anemia (AIHA).

Prospective, double-blind, randomized, placebo-controlled First-In-Human study with four sub-parts: Part A, a single ascending dose study (SAD) in normal human volunteers (NHVs), Part B, a multiple ascending dose study (MAD) in NHVs, Part C, a multiple dose (MD) study in patients with a complement-mediated disorder, and Part E, a multiple dose (MD) study in patients with cold agglutinin disease previously treated with BIVV009 within the scope of a BIVV009 clinical trial or named patient program use. Note: For parts A-C as well as at the start of part E, study drug was named TNT009. The study drug name is changed to BIVV009 with final version Final 15.0 of the clinical study protocol.

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.

This study is to assess the safety, tolerability, preliminary efficacy, and pharmacokinetics of APL-2 in subjects with warm Autoimmune Hemolytic Anemia (wAIHA) or Cold Agglutinin Disease (CAD).

The aim of this prospective study was to evaluate the activity, safety and the duration of the response of low dose rituximab associated with standard oral prednisone as first line therapy in newly diagnosed warm autoimmune hemolytic anemia and cold hemagglutinin disease, and as second line therapy in warm autoimmune hemolytic anemia relapsed after standard oral prednisone. Further aim was to correlate the clinical response to biological parameters (cytokine and anti-erythrocyte antibody production in cultures).

Platelets are particles found along with red and white blood cells in the blood that play a role in the process of blood clotting. Disorders affecting the platelets can lower the amount of platelets in the blood and put patients at risk of bleeding. The condition of low platelets is referred to as thrombocytopenia. Thrombocytopenia can be associated with a variety of diseases including cancer, leukemia, tuberculosis, or as a result of an autoimmune reaction. Autoimmune reactions are disorders in which the normal immune system begins attacking itself. Autoimmune thrombocytopenia (AITP) is a disorder of low blood platelet counts in which platelets are destroyed by antibodies produced by the immune system. Unfortunately, many patients with AITP do not respond to standard treatments for thrombocytopenia. Cyclophosphamide is a drug that works to suppress the activity of the immune system. Researchers believe that combining this drug with transplanted rescued blood stem cells may provide effective treatment for AITP. The purpose of this study is to explore the affordability and safety of this therapy for the treatment of AITP. The effectiveness of the therapy will be measured by the number of patients whose platelet levels rise greater than 100,000/m3. If this treatment approach appears affordable, this study will form the basis for a larger study to compare alternate treatment approaches.

Although many studies investigated the prevalence and manifestations of HPV-B19 infection in patients with sickle cell anemia (SCA), thalassemia, and hereditary spherocytosis (HS) separately, there is limited information about the extent to which HPV-B19 infection leads to severe complications and chronic infection.

OBJECTIVES: I. Determine the response rate and 1-year event-free survival in patients with severe autoimmune hematologic disease treated with high-dose cyclophosphamide.

The main objective of the study is to evaluate the safety and efficacy of ALXN1830 compared to placebo in adult participants with warm autoimmune hemolytic anemia (WAIHA).

Some patients with antibody-mediated autoimmune hematological diseases (warm autoimmune hemolytic anemia (wAIHA), cold agglutinin disease (cAIHA) and immune thrombocytopenia (ITP)) shows no or only minor and transient response to therapy despite several treatment-lines. Such patients are more likely to have a severe disease, with a higher morbidity and mortality. Hypothesis Effective depletion of autoreactive plasma cells might be the key for a curative approach of these diseases. Therefore, there is a rationale for using proteasome inhibitors (PIs) in these refractory patients. The rationale is that non-tumoral autoreactive plasma cells are rapidly targeted by proteasome inhibitors. It led us to propose a short course of dexamethasone and ixazomib (5 cycles), to evaluate the safety/efficacy of this innovative strategy of treatment. Method Prospective interventional uncontrolled single arm open study evaluating the rate of patients achieving 5 cycles of ixazomib and dexamethasone without severe toxicity and response on therapy.
