NCT ID: NCT05991245 Recruiting - Acute Kidney Injury Clinical Trials

French National Cohort MATRIX "Renal and Systemic Thrombotic Microangiopathy"

MATRIX
Start date: January 1, 2023
Phase:
Study type: Observational

Thrombotic microangiopathies (TMAs) are a diverse, rare but serious group of diseases. Progress has been made regarding the epidemiology of TMA (Bayer CJASN 2019). It has been shown that secondary TMAs account for 95% of cases, whereas primary TMAs (atypical hemolytic syndromes (HUS) and thrombotic thrombocytopenic purpura (TTP)) account for only about 5%. However, in many cases, the pathophysiology, optimal management and prognosis of TMA remains unclear and it has been shown that patients with TMA may have renal-limited TMA or renal and hematological TMA (ie. With (mechanical anemia, thrombocytopenia, elevated LDH, decreased haptoglobin, schistocytes). In most studies, kidney biopsies are not performed and the diagnostic workup is uncomplete. As this is a rare disease, only a multicenter approach (>20 centers) over a long period of time (>10 years), with adequate diagnostic workup including kidney biopsies can help us to answer these questions (investigators in the present are usually members of the CNR-MAT (a network of the TMA centers in France).

NCT ID: NCT05982938 Available - Clinical trials for Paroxysmal Nocturnal Hemoglobinuria

Danicopan Early Access Program

Start date: n/a
Phase:
Study type: Expanded Access

This is an EAP, designed to provide early access to danicopan for participants with PNH experiencing clinically significant EVH who have failed, not tolerated, or are unable to receive other approved treatments; in the Treating Physician's opinion, the participant is not eligible for or is not able to participate in an ongoing clinical trial of danicopan or a comparable treatment; and according to the Treating Physician, the benefit of danicopan treatment outweighs the potential risks.

NCT ID: NCT05931718 Recruiting - Clinical trials for Myelodysplastic Syndromes

Prospective Evaluation of Diagnosis and Treatment of Patients With Autoimmune Cytopenias Including Autoimmune Hemolytic Anemia, Immune Thrombocytopenia, and Chronic Idiopathic/Autoimmune Neutropenia

AIHA ITP CIN
Start date: June 1, 2021
Phase:
Study type: Observational

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.

NCT ID: NCT05925023 Recruiting - Clinical trials for Warm Autoimmune Hemolytic Anemia

Sirolimus in the Treatment of Refractory/Relapsed wAIHA

Start date: June 24, 2023
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT05922839 Not yet recruiting - Clinical trials for Warm Autoimmune Hemolytic Anemia

Zanubrutinib in the Treatment of Relapsed/Refractory wAIHA

Start date: June 2023
Phase: Phase 2
Study type: Interventional

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. Bruton's tyrosine kinase (BTK) plays a crucial role in the signaling pathway of B-cell receptor (BCR), and has been found to be a major source of pathogenic signal transduction for various lymphoproliferative malignancies. The activity of BTK is related to the occurrence and progression of various B-cell lymphomas. Currently, BTK inhibitors are widely used in the treatment of B-cell lymphomas, including chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), Waldenstrom's macroglobulinemia (WM), and other B-cell lymphomas, showing significant efficacy. BTK affects the production of messenger molecules and regulates the BCR signaling pathway, causing B cells to transform into self-reactive B cells, which can trigger autoimmune diseases. Current research has shown that BTK activity increases in several autoimmune diseases, including systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) . Therefore, BTK inhibitors (BTKi) are important for the treatment of autoimmune diseases. Ibrutinib, one kind of BTKi, has been proven to treat secondary autoimmune hemolytic anemia (AIHA) in CLL and control CLL progression, and is an effective drug for treating lymphoma-associated AIHA . One kind of second-generation selective BTKi, acalabrutinib, can also reduce the incidence of AIHA in relapsed or refractory CLL patients. Currently, phase-II clinical studies exploring the treatment of AIHA using Ibrutinib, acalabrutinib, and rilzabrutinib, another BTKi, are underway. Zanubrutinib (BGB-3111, Brukinsa®, BeiGene) is a second-generation irreversible BTKi developed by Chinese company BeiGene. Compared to Ibrutinib, zanubrutinib has shown stronger effective activity and higher selectivity towards BTK, and weaker effects on other targets such as TEC, EGFR, and Src families, with low off-target side effects. Its efficacy, durability, oral absorption, and targeting are better than those of Ibrutinib. Zanubrutinib is approved for the treatment of various B-cell lymphomas, and clinical trials have shown excellent efficacy and tolerability in CLL and WM patients. In previously treated CLL patients, zanubrutinib exhibits better efficacy and safety than Ibrutinib. Currently, phase II clinical studies of zanubrutinib in ITP, antiphospholipid syndrome, IgG4-related immune diseases, and active proliferative lupus nephritis are underway. The therapeutic effect of zanubrutinib on refractory warm autoimmune hemolytic anemia, is worth exploring through exploratory research.
