Active clinical trials for "Thrombocytopenia"

ITP patients with low platelet count and active bleeding symptoms are at risk of life-threatening bleeding and therefore require a treatment with a rapid effect, reliable, and sustained. The combination of intravenous immunoglobulin (IVIg) and prednisone (1 mg/kg per day), is more rapidly and more frequently effective than high dose methylprednisolone to increase the platelet count. This combination is therefore usually given in patients with platelets count < 20 x 109/L and moderate to severe bleeding manifestations. Based on common practice in France and on French ITP guidelines, on average 50 % of patients with ITP and profound thrombocytopenia do actually receive IVIg (mostly during the initial phase of the disease) corresponding to approximately 1,500 ITP patients per year in France. Whereas IVIg is usually well tolerated, renal insufficiency and congestive heart failure may occur, moreover IVIg are costly and non-easily available with supply difficulties in many countries including France. High dose dexamethasone (DXM) (ie: 40 mg/d for 4 days) has recently emerged as a promising treatment for ITP. One recent meta-analysis as well as a controlled prospective trial suggest that the initial overall response was higher (> 80 %) and the time to response was shorter with dexamethasone (DXM) 40 mg/d given for 4 days compared to standard prednisone. The investigators hypothesize that DXM could be a reasonable non-inferior alternative to IVIg, more convenient for patients with less adverse events and economically cost-effective for patients with moderate and severe bleeding manifestations.

To evaluate the safety and efficacy of zanubrutinib in the treatment of antiphospholipid syndrome with secondary thrombocytopenia in 10 patients.

In this study, investigators aimed to evaluate the efficacy of Avatrombopag in thrombocytopenic patients with chronic liver disease undergoing an elective invasive procedure through a prospective, non-randomized controlled, multicenter clinical trial. The patients were non-randomly assigned to the Avatrombopag group (119 patients) and the conventional treatment group (357 patients). The primary endpoint was the proportion of patients not requiring prophylactic platelet transfusion or rescue therapy due to bleeding from grouping up to 10 days post-procedure. Second endpoints included the proportion of patients achieving a platelet count of ≥50x10^9/L and the mean change in platelet count from baseline at the time before the procedure, the proportion of patients requiring platelet transfusion and the mean platelet transfusion units per capita, the incidence of bleeding events (WHO≥2 and requiring rescue therapy), the imaging evaluations of bleeding events, the incidence of adverse events, the changes in life quality between two groups before and after treatment, and the pharmacoeconomic index of two groups. Note: According to the results of interim statistical analysis (200-300 cases), it is up to the sponsor to decide whether to terminate the study in advance or increase the number of included cases at a later stage.

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.

A Phase 3b Study to Evaluate the Efficacy and Safety of Avatrombopag for the Treatment of Thrombocytopenia in Pediatric Subjects with Immune Thrombocytopenia for ≥6 Months

This is an open-label, multicenter study exploring the efficacy of ivosidenib in patients with clonal cytopenia of undetermined significance (CCUS) with mutations in IDH1. The purpose is to establish proof of principle that ivosidenib is well-tolerated and potentially efficacious in improving blood count abnormalities in these patients. The study will also be offered in a decentralized, remote structure to patients.

The purpose of this study is to determine if using avatrombopag in patients with thrombocytopenia due to temozolomide treatment can safely improve a patient's platelet count and allow the patient to complete the temozolomide treatment course as planned.

This is a phase II pilot study designed to assess the safety and efficacy of danazol for treatment of cytopenias in patients with CPC A/B cirrhosis. Subjects with or without telomere mutations and/or shortened telomeres will be treated with danazol 600 mg per day by mouth for a duration of 24 months. The goal will be to treat a total of 10 patients.

This is a prospective, open-label, single-arm, multicenter, Phase 4 study evaluating the efficacy and safety of PANZYGA in pediatric patients with chronic ITP.

Background: CTLA4 stands for cytotoxic T-lymphocyte antigen-4. It is a protein the body makes naturally to check its immune system from attacking itself. Some people don t produce enough CTLA4 protein, causing problems due to overactive immune system such as big spleens, repeated lung infections, breathing problems, stomach and intestine symptoms as well as inflamed brain and nerve problems. Many have problems with their bone marrow causing low numbers of blood cells like platelets, red blood cells or white blood cells, which is called cytopenia. Researchers want to see if the drug abatacept can treat cytopenias by replacing the missing protein CTLA4. Objective: To see if abatacept is safe and helps treat cytopenias caused by CTLA4 deficiency. Eligibility: People ages 8-65 years who have CTLA4 deficiency with cytopenia Design: Participants will be screened with medical history, medication review, physical exam and blood and urine tests. They will continue their current medications and may start taking antibiotics daily. Participants will receive either abatacept or placebo through a vein for 6 months. The study team will not know if you are receiving the study drug or the placebo Women who can become pregnant must agree to use birth control measures. Men who get someone pregnant during the study will be asked to collect information and have the partner contact the study team. Participants will undergo the following procedures before starting the study and at the completion: radiology scans of body and brain heart and lung function tests Bone marrow examination by a needle inserted into the hip bone to remove a small amount of tissue to study. Participants may have a small camera on a long, thin tool passed down the throat into the stomach and small intestine for evaluation of their gut. Questionnaires about their disease, symptoms and quality of life Over 6 months, participants will have regular study visits and get 8 doses of the study drug or a placebo by intravenous injection. They will repeat some of the same tests done earlier at the end of the study at assess response. About 1 month after the last study drug visit, participants will have a final study visit. Some participants may join a treatment extension for the study drug abatacept with no placebo. They will sign a separate consent form for this.
