Active clinical trials for "Anemia, Hemolytic, Autoimmune"

Autoimmune hemolytic anemia (AIHA) is a rare and heterogeneous disorder characterized by the destruction of red blood cells through warm or cold antibodies. Glucocorticoid (combined with rituximab) is the first-line treatment. However, the recurrence rate is very high and some patients may not respond to steroids. Second-line therapies include cyclosporine A (CsA), cyclophosphamide, rituximab, azathioprine, and even splenectomy. Our previous study of sirolimus in refractory/relapsed AIHA and ES found an effective rate of 80%. Therefore, the investigators plan to explore the efficacy and safety of sirolimus in the treatment of refractory/relapsed wAIHA.

The primary objective of this study is: • To evaluate the long-term safety of fostamatinib in subjects with warm antibody autoimmune hemolytic anemia (wAIHA).

The purpose of this study is to evaluate the safety and efficacy of parsaclisib administered orally to participants with autoimmune hemolytic anemia (AIHA) who have decreased hemoglobin and evidence of ongoing hemolysis that requires treatment intervention.

Primary Objective: To assess the long-term safety and tolerability in patients with cold agglutinin disease (CAD), after multiple doses of SAR445088 Secondary Objective: To assess, in patients with cold agglutinin disease (CAD), after multiple doses of SAR445088: The long-term effect of SAR445088 on complement mediated hemolysis The long-term pharmacodynamics (PD) effect of SAR445088 relating to complement inhibition The long-term pharmacokinetic (PK) profile of SAR445088 The long-term immunogenicity of SAR445088

Phase II Study: To evaluate the safety and preliminary efficacy of HMPL-523 in adult patients with wAIHA Phase III Studies: Confirmation of Efficacy safety and of HMPL-523 in Adult Patients With wAIHA

The purpose of this study is to evaluate the efficacy and safety of parsaclisib compared with placebo in participants with Primary Warm Autoimmune Hemolytic Anemia (wAIHA),

The main purpose of this study is to evaluate the efficacy and safety of iptacopan in participants with autoimmune benign hematological disorders such as primary immune thrombocytopenia and primary cold agglutinin disease.

This phase II trial studies the effect of acalabrutinib in treating autoimmune hemolytic anemia that has come back (relapsed) or has not responded to previous treatment (refractory) in patients with chronic lymphocytic leukemia. Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Autoimmune hemolytic anemia (AIHA) is a rare autoimmune disease (incidence <1/100,000 population) responsible for the destruction of red blood cells by the host immune system, notably through the action of autoantibodies. Apart from complications related to anemia, the occurrence of venous thromboembolism (VTE) in this population is frequent, estimated at 20-27%. The risk of VTE is highest during the period of hemolysis, especially during the first 3 months after the diagnosis of AIHA. This risk is 7.5 [4.7; 12.0] times greater than in the general population. No clinical predictive factor for VTE was identified and the usual factors (cancer, previous VTE, bed rest >3 days, surgery, age >70 years, heart or respiratory failure, myocardial infarction, stroke, obesity, hormone replacement therapy) were not considered. Several biological risk factors have been suggested (depth of anemia, bilirubin level, leukocyte count, antiphospholipid antibodies) but have not been confirmed in other studies. AIHA is therefore a risk factor for VTE in its own right, and the National Diagnostic and Care Protocol (NDCP) recommends the implementation of VTE prevention during acute hemolysis (Grade C). However, the value of this prophylaxis has never been prospectively evaluated and its duration is empirical. In practice, low-molecular-weight heparin (LMWH) is generally used during "flare-ups" of AIHA (diagnosis and relapse) in hospitalized patients, but is rarely continued beyond the hospital phase when VTE also occurs in ambulatory patients. Thus, we hypothesize that prolonged preventive anticoagulation during the 12-week risk period following diagnosis or relapse of AIHA could decrease the incidence of VTE. In orthopedic surgery, this strategy has been proven to decrease VTE from 50% to 10-15%. In certain high-risk medical situations, prolonged prophylaxis with apixaban has been shown to decrease the occurrence of VTE from 10.2% to 4.2% in solid cancers4 and from 4-11% to 2% in myeloma.

The goal of this observational study is to characterize the diagnostic and therapeutic management of autoimmune cytopenias including autoimmune hemolytic anemia, immune thrombocytopenia, and chronic idiopathic/autoimmune neutropenia. The main aims to answer are: evaluation of traditional and novel diagnostic tools including immunohematology, cytokine essays, bone marrow studies, molecular findings, and fecal microbiome. evaluation of type and sequence of the therapies administered, the response rates, and the adverse events. evaluation of clinical and laboratory (immunologic, molecular, and morphologic) predictors of outcome. evolution of autoimmune cytopenias into myelodysplastic syndromes. a subgroup of patients with myelodysplastic syndromes will be included to evaluate the presence of immunologic events, autoimmune activation, and red cell metabolism. Participants will receive a clinical/laboratory diagnostic workup as per current clinical practice. Furthermore They will be sampled at baseline (peripheral blood and feces for microbiome) and followed up for at least 3 years to evaluate their clinical course, therapeutic management and outcome.
