Active clinical trials for "Thrombocytopenia"

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 12-week randomized, open-label study evaluates the efficacy and safety of Tacrolimus combined with Glucocorticoid for Sjogren's syndrome patients with severe thrombocytopenia.

Determine whether clinical decision support (best practice advisory) improves provider adherence to transfusion guidelines for all four major blood components (red blood cells, plasma, platelets, and cryoprecipitate) using a randomized study design to reduce risk of bias. Alerts will be visible to the experimental ordering provider group, while they will not be visible to the control. Both groups still have access to information about best practices: local clinical transfusion guidelines are available and education on blood transfusion best practices will continue regardless of randomization assignment.

The purpose of this study is to compare the efficacy of two study drugs, Avatrobopag versus placebo, to treat persistent Chemotherapy-Induced Thrombocytopenia (CIT) in patients with gastrointestinal (GI) malignancies receiving cytotoxic chemotherapy. The names of the study drugs involved in this study are: Avatrombopag (a thrombopoietin receptor agonist) Matching placebo

Randomized, controlled, open study to evaluate the efficacy and safety of Hetrombopag in the treatment of chemotherapy-induced thrombocytopenia(CIT) in patients with acute myeloid leukemia

If your serious vaccine-induced adverse event has been entered in the CDC Vaccine Adverse Event Reporting System (VAERS) we are interested in enrolling you for this study in order to log your symptoms. The primary goal of this study is to create a national database and gather vaccine-associated serious adverse events/injury data from newly vaccinated individuals in the US in order to identify the possible underlying causal relationships and plausible underlying biological mechanisms. The project aims to identify the genetic determinants of vaccine-induced adverse response by studying host genetics. We plan to use whole genome sequencing to identify single nucleotide polymorphisms associated with cardiovascular, neurological, gastrointestinal, musculoskeletal and immunological symptoms induced by vaccine administration. The secondary goal is to establish criteria that enable classification of vaccine-induced adverse events/injuries compare data from our database with the official Vaccine Injury Table National Vaccine Injury Compensation Program on or after March 21, 2017. The tertiary goal is to establish a database to gather detailed long-term adverse reaction data from subjects enrolled in FDA Emergency Use Authorized vaccine clinical trials.

This study developed the first prediction model for risk of critical ITP bleeds for ITP inpatients using a novel machine learning algorithm. This model has been implemented as a web-based model so that clinicians can obtain the estimated probability of critical ITP bleeds for ITP inpatients. The objective of this study is to prospectively and externally validate the risk of critical ITP bleeds in newly admitted ITP patients.

Prolonged isolated thrombocytopenia (PIT) that is refractory to conventional treatments has remained a critical complication after allogeneic hematopoietic cell transplantation since decades years ago. Recombinant human thrombopoietin (rhTPO) is the main therapy in clinical practice, but remains low efficiency for PIT. Demethylating drugs have shown thier potential in high-risk myelodysplastic syndromes (MDS) and acte myeloid leukemia (AML). In addition, decitabine has demonstrated its efficacy of over 70% for response rate in treatment for PIT in early clinical trials with elusive mechanism. Preliminary experiments revealed that PIT was associated with abnormality of oxidation microenvironment, and N-Acetyl-L-cysteine (NAC) was the most commonly used antioxidant. Therefore, the investigators have been wondering whether Azacitidine in combination with NAC could improve PIT post HSCT and explore the possible mechanism of it.

The purpose of the study is to explore the safety and efficacy of umbilical cord derived mesenchymal stem cells in treatment-induced myelosuppression in patients with hematologic malignancies.

The is a phase 2, single-arm, open-label clinical study assessing the efficacy and safety of hetrombopag to increase platelet count in lower-risk MDS patients with thrombocytopenia.
