Active clinical trials for "Anemia, Hemolytic, Autoimmune"

Chronic cold agglutinin disease (CAD) is a type of autoimmune hemolytic anemia (anemia due to destruction of red blood cells by abnormal antibodies). Almost all patients also suffer from cold-induced disturbances of blood circulation. The purpose of this study is to assess the efficacy and safety of combination therapy with rituximab (an antibody against B lymphocytes) and fludarabine (a cytotoxic drug) for CAD. Another aim is to try to assess whether these agents in combination are better than single agent therapy with rituximab.

The purpose of Part A was to determine whether sutimlimab administration resulted in a greater than or equal to (>=)1.5 grams per deciliter (g/dL) increase in hemoglobin (Hgb) level and avoidance of transfusion in participants with primary cold agglutinin disease (CAD) without a recent history of blood transfusion. The purpose of Part B was to evaluate the long-term safety and tolerability of sutimlimab in participants with primary CAD.

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.

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.

This is a Phase 2 randomized, dose-blind, multicenter study designed to evaluate the safety, tolerability, efficacy, Pharmacokinetics (PK), and Pharmacodynamics (PD) of treatment with KZR-616 in patients with active Autoimmune Hemolytic Anemia or Immune Thrombocytopenia.

This is a Phase 2, multiple ascending, dose-finding, randomized, double-blind, placebo-controlled study to evaluate the efficacy, safety, health-related quality of life, tolerability, pharmacokinetic, pharmacodynamic, and immunogenicity, of up to 3 dose regimens of ALXN1830 administered subcutaneous(ly) (SC) in the treatment of WAIHA. This study will include 2 randomized, double-blind, placebo-controlled cohorts (Cohorts 1 and 2) to evaluate an 8-week treatment regimen, and an optional third open-label cohort (Cohort 3) to evaluate an alternative 12-week dosing regimen. Participants may continue participation in this study at the participant's and investigator's discretion in an open-label extension (OLE) period, consisting of monthly visits to observe participants for relapse, which will require going back on active treatment.
