Filter by:This is a Phase 1, single-arm, open-label, dose-escalation and dose-expansion study. The main purpose is to evaluate the safety and tolerability, efficacy of CNCT19 CAR T-cell therapy in patients with autoimmune hemolytic anemia after failure of three or more lines of therapy. Participants will receive CNCT19 cell infusion after preconditioning, and they will receive a 1-year follow-up.
To Evaluate the Safety and Efficacy of ThisCART19A for Relapsed/Refractory Autoimmune Hemolytic Anemia Patients After Receiving Three or More Lines of Therapy
From 2004, OBS'CEREVANCE is a national real-world prospective clinical cohort of patients with auto-immune cytopenia of pediatric-onset : Immune thrombocytopenia (ITP), Autoimmune Hemolytic anemia (AIHA), or Evans syndrome (all bi or tri cytopenias). Thanks to the collaboration of the 30 French pediatric hematologic centers, this cohort supports all of the Rare Disease Centre CEREVANCE (Centre de Référence National des Cytopénies Auto-Immunes de l'Enfant) missions for care, education and research. Specifically, this original unbiased database allows to describe the long-term health of adult patients, to identify the heterogenous genetic underlying pathophysiologic contexts, and to study the benefit-risk balance of treatments, including the growing development of targeted therapies.
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.
1. Study the presence of circulating CD4+/CD28 null T lymphocytes in AIHA either Idiopathic or Secondary. 2. Role of CD4+/CD28 null T lymphocytes in monitoring response to therapy in AIHA.
This is a multicenter, single arm, phase II study aimed at evaluating ibrutinib therapy for the treatment of AIHA in patients with CLL/SLL or CLL-like MBL.
This is a prospective, multicenter, single-arm, pilot study. The aim of this study is to evaluate the efficacy and safety of Linperlisib, the PI3K delta inhibitor for autoimmune hemolytic anemia patients who failed the second line therapy.
A Clinical Study on the Safety and Effectiveness of CD19/BCMA Chimeric Antigen Receptor T Cells in the Treatment of Refractory POEMS Syndrome, Amyloidosis, Autoimmune Hemolytic Anemia, and Vasculitis
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.
There is a deficiency in guidelines about the treatment of autoimmune hemolytic anemia in systemic lupus erythematosus (SLE), especially in refractory cases. Mycophenolate mofetil (MMF) showed promising results in those patients but still, the data available are in form of case reports. So, investigators will investigate the efficiency of MMF against a well-established treatment Rituximab in the treatment of refractory autoimmune hemolytic anemia in SLE patients.
