NCT ID: NCT06439173 Recruiting - Clinical trials for Diffuse Large B Cell Lymphoma

Study of the Hematopoietic Niche and the Role of Inflammation in the Pathophysiology of Cytopenias After CAR-T Cell Therapy: Potential of Therapies Directed to Repair the Bone Marrow Microenvironment

Start date: January 1, 2024
Phase:
Study type: Observational

Immunotherapy with chimeric antigen receptor T-cells (CAR-T) has revolutionized the treatment of oncohematological diseases and its applications in solid tumors and non-neoplastic diseases are advancing. Cytopenias after CAR-T therapy are the most frequent complication in the medium and long term after treatment, they are a cause of morbimortality, and there are no effective therapies available. The general objective of the present research project is to analyze, in a series of 40 patients with diffuse large B-cell lymphoma undergoing consecutive commercial CAR-T therapy at the University Hospital of Salamanca, the characteristics of the hematopoietic niche and the systemic and bone marrow inflammatory status in patients with prolonged cytopenias after CAR-T cell therapy with respect to those without cytopenias and with respect to the pre-treatment situation (performing quantitative and functional analysis of the stroma by immunohistochemistry, flow cytometry and genomic studies, in addition to functional hematopoietic assays-clonogenic assays, long-term cultures-), and to evaluate both in vitro (by co-culturing with macrophages activated by CAR-T/tumor cell interaction and assessing cytokines) and in vivo (in an animal model of lymphoma and CRS) the therapeutic potential of therapies aimed at repairing the hematopoietic bone marrow microenvironment, such as the use of allogeneic mesenchymal cells (MSC) from healthy donors and MSC-derived extracellular vesicles (MSC-EV) studying their effects on inflammatory mediators, hematopoiesis and the cytotoxic effect of CAR-T.

NCT ID: NCT06276036 Active, not recruiting - Cytopenia Clinical Trials

Autoimmune Cytopenias as a Sign of Primary Immunodeficiency.

Start date: July 23, 2019
Phase: N/A
Study type: Interventional

Autoimmune cytopenias resistant to treatment are among the most common clinical manifestations observed in patients with congenital alterations of the immune system, such as primary immunodeficiencies (PI). The exact contribution of immune system alterations to the pathogenesis of autoimmune cytopenias has not yet been fully elucidated. Moreover, conventionally employed therapeutic strategies often fail, leading to increased healthcare costs, high morbidity, and even mortality. Therefore, there is a need to establish clinical guidelines for diagnosis and to identify early biomarkers capable of identifying individuals responsive to therapy. Thus, a systematic approach to the study of such pathologies will allow for the identification of early biomarkers and facilitate the development of targeted therapeutic strategies

NCT ID: NCT06240754 Not yet recruiting - Clinical trials for Clonal Cytopenia of Undetermined Significance

Enasidenib for Patients With Clonal Cytopenia of Undetermined Significance and Mutations in IDH2A Decentralized Trial

Start date: June 30, 2024
Phase: Phase 2
Study type: Interventional

Study researchers think that a drug called enasidenib may help people with clonal cytopenia of undetermined significance (CCUS) because the drug blocks the mutated IDH2 protein, which may improve blood cell counts. The purpose of this study is to find out whether enasidenib is a safe and effective treatment for CCUS.

NCT ID: NCT06063486 Recruiting - Clinical trials for Myelodysplastic Syndrome

Curcumin to Improve Inflammation and Symptoms in Patients With Clonal Cytopenia of Undetermined Significance, Low Risk Myelodysplastic Syndrome, and Myeloproliferative Neoplasms

Start date: March 1, 2024
Phase: Phase 2
Study type: Interventional

This phase II trial evaluates how a curcumin supplement (C3 complex/Bioperine) changes the inflammatory response and symptomatology in patients with clonal cytopenia of undetermined significance (CCUS), low risk myelodysplastic syndrome (LR-MDS), and myeloproliferative neoplasms (MPN). Chronic inflammation drives disease development and contributes to symptoms experienced by patients with CCUS, LR-MDS, and MPN. Curcumin has been shown to have anti-inflammatory and anti-cancer properties and has been studied in various chronic illnesses and hematologic diseases.

NCT ID: NCT05998408 Recruiting - Clinical trials for Severe Aplastic Anemia

JAK1/2 Inhibitor Ruxolitinib for Relapsed/Refractory Immune Bone Marrow Failure

Start date: February 20, 2024
Phase: Phase 1/Phase 2
Study type: Interventional

Background: Immune bone marrow failure is a condition that occurs when a person s immune system attacks the cells of the bone marrow. This can lead to diseases including different types of anemias and blood cancers. Some of these diseases can be deadly. Better treatments are needed. Objective: To test a drug (ruxolitinib) in people with different types of immune bone marrow failure. Eligibility: Adults aged 18 and older with an immune bone marrow failure. Design: Participants will be screened. They will have a physical exam. They will give samples of blood and saliva. They will have a bone marrow biopsy: A large needle will be inserted into a small cut to remove a sample of the soft tissue inside the bone. Some participants may have a skin biopsy: A small piece of skin will be removed. Some may have a computed tomography (CT) scan: They will lie on a table that slides into a donut-shaped machine that uses X-rays to make pictures of the inside of the body. Ruxolitinib is a tablet taken by mouth. Participants will take the drug twice a day for up to 6 months. Participants will have blood tests every week while they are taking the drug. These tests can be done by the participant s own physician and the results sent to the researchers. Participants will have clinic visits after taking the drug for 3 months and 6 months and then after 1, 2, and 3 years. The blood tests and bone marrow biopsy will be repeated. Participants who improve while taking the drugs may go on to an extension phase of the study.

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.
