Filter by:The objective of this expanded access protocol (EAP) is to provide access to treatment with imetelstat, the Investigational Product (IP), for eligible adult participants diagnosed with very low, low, intermediate risk (by Revised International Prognostic Scoring System, IPSS-R) myelodysplastic syndromes (MDS) who are red blood cell (RBC) transfusion-dependent, have failed to respond or have lost response or are ineligible for ESAs, had not received prior treatment with either a hypomethylating agent or lenalidomide and were non-del(5q), until such time that imetelstat becomes commercially available.
INMB-INB16-002 is a Phase I open-label, dose escalation study of INKmune therapy in subjects with myelodysplastic syndrome (MDS) with excess blasts without Auer rods (EB-1 or 2, or CMML 1 or 2) or subjects with acute myeloid leukaemia (AML) in complete remission.
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.
This is a prospective, single center, single-arm, phase 2 study. The aim of this study is to evaluate the efficacy and safety of Luspatercept for Patients with Lower-risk Myelodysplastic Syndromes (MDS).
Myelodysplastic syndromes, primarily affecting older adults, are a heterogeneous group of clonal disorders of hematopoietic stem cells characterized by ineffective hematopoiesis that manifest clinically as anemia, neutropenia, and/or thrombocytopenia of variable severity; these often result in RBC- transfusion dependent (TD) anemia, increased risk of infection, and/or hemorrhage, as well as a potential to progress to acute myeloid leukemia (AML). Lenalidomide is approved for red blood cell transfusion-dependent (RBC TD) anemia due to low-risk myelodysplastic syndromes (MDS) with a chromosome 5q deletion (del5q) with or without additional cytogenetic abnormalities. About one third of patients are refractory/resistant/intolerant and will require further treatment options. Luspatercept (ACE-536), an erythroid maturation agent, is a recombinant fusion protein consisting of a modified form of the extracellular domain (ECD) of the human activin receptor type IIB (ActRIIB) linked to the Fc portion of human immunoglobulin G1 (IgG1-Fc). Luspatercept acts on endogenous inhibitors of late-stage erythropoiesis (eg, growth differentiation factor 11, GDF11) to increase release of mature erythrocytes into circulation. Nonclinical data have demonstrated that luspatercept binds to negative regulators governing late-stage erythroid development to inhibit their action, thereby promoting the maturation of erythrocytes in the bone marrow. Luspatercept is indicated for the treatment of adult patients with transfusion-dependent anaemia associated with beta-thalassaemia and due to very low, low and intermediate-risk MDS with ring sideroblasts, who had an unsatisfactory response to or are ineligible for erythropoietin-based-therapy. It is not indicated for other MDS subtypes. Unfortunately, patients with MDS with del5q refractory/resistant/intolerant to lenalidomide are excluded from clinical trials that evaluate novel treatments for the anemia of RBC TD lower risk MDS. Therefore, treatment of anemia in such patients is an unmet need. QOL-ONE Phoenix is a Phase 2, multicenter, single arm, prospective study. The primary objective of the study is to evaluate the effect of luspatercept on RBC TI in subjects with MDS with del5q with IPSS-R very low, low, or intermediate risk and < 5% bone marrow blasts, resistant/refractory/intolerant to lenalidomide and who require RBC transfusions. The study is divided into a Screening Period, a 2-year Treatment Period and a 3-year Follow-up Period. Primary objective is to evaluate the effect of luspatercept on RBC TI (lack of transfusions for 8 consecutive weeks within the first 24 weeks) in subjects with MDS with del5q with IPSS-R very low, low, or intermediate risk and < 5% bone marrow blasts, resistant/refractory/intolerant to lenalidomide and RBC TD.
Myelodysplastic syndromes (MDS) are clonal diseases of hematopoietic stem cells (HSC) characterized by dysplastic and inefficient hematopoiesis related to excessive progenitor cell death. Ferroptosis is a recently described cell death mechanism and we think that it could be a major player in the pathophysiology of MDS, involved in the cell death that characterizes these diseases and contributing to cytopenias. The study aims to demonstrate that there is a significant activation of this phenomenon in MDS patients compared to a population of subjects without MDS.
Background: Myelodysplastic syndromes (MDS) are diseases that affect the bone marrow. They can inhibit the blood formation process and reduce blood cell counts. High-risk MDS can lead to leukemia. People with high-risk MDS have a low survival rate. Better treatments are needed. Objective: To test a study drug (KPT-8602), combined with another drug (Inqovi), in people with MDS. Eligibility: Adults aged 18 years and older with high-risk MDS that did not respond to treatment. Design: Participants will be screened. They will have a physical exam. They will have blood and urine tests and tests of their heart function. They may have a bone marrow biopsy: Their hip will be numbed; then a needle will be inserted to draw out a sample of soft tissue from inside the bone. They will answer questions about their quality of life. Genetic tests may be performed. KPT-8602 and Inqovi are both tablets taken by mouth. Participants will take these drugs at home on a 28-day cycle. They will take Inqovi once a day on days 1 to 5. They will take KPT-8602 on a schedule assigned by the researcher. Participants will be given a drug diary to record each dose. Participants will visit the clinic for an exam at least once in each cycle. Some tests, including the bone marrow biopsy, may be repeated. Participant will continue treatment for at least 6 cycles. If their disease improves, they may continue taking the drugs after 6 cycles. Participants will have follow-up visits at the clinic for about 8 years.
A Phase 1 study in subjects with LR-MDS to assess the safety and tolerability of JSP191 as a second-line therapy.
This study is an open, prospective, single-center, single-arm study expanded based on the study of NCT03412409.The primary objective of this study is to evaluate the transplantation efficacy of the RIC conditioning regimen in elderly patients receiving the transplantation of haploidentical hematopoietic stem cells. Elderly patients are defined as ≥55 years of age; High comorbidity is defined as an HCT-CI score ≥3.Primary endpoint is 1-year LFS. Secondary endpoints are 1-year OS and 1-year TRM, Other indicators to be assessed in this study include acute GVHD, chronic GVHD, CMV activation, EBV activation, engraftment.
The purpose of this study is to evaluate the safety and effectiveness of luspatercept in participants who require regular blood cell transfusions due to b-thalassemia and myelodysplastic syndromes in India
