Prospective Study of Patients With Thrombocytopenia Following HSCT

Status Completed

Clinical Trial Summary

Isolated thrombocytopenia is a common and severe complication of HSCT, which often leads to an increased risk of life-threatening hemorrhage, frequent requirement of platelet transfusions and extended hospital stays, representing a challenging clinical problem. Current treatments for thrombocytopenia after HSCT are frequently unsatisfactory in platelet recovery and for preventing potentially fatal bleeding complications. Therefore, it is urgent to explore an effective therapy to improve the outcomes of thrombocytopenia after HSCT. Previous studies have demonstrated that decitabine, a hypomethylating agent, may reduce platelet transfusions in myelodysplastic syndrome (MDS) patients. The investigators conducted an prospective clinical trial to evaluate the safety and efficiency of rhTPO and decitabine in the treatment of thrombocytopenia following HSCT.

Clinical Trial Description

Isolated thrombocytopenia is a frequent and severe complication of hematopoietic stem cell transplantation (HSCT). It often leads to an increased risk of life-threatening hemorrhage, frequent requirement of platelet transfusions and extended hospital stays, representing a challenging clinical problem. Current treatments for thrombocytopenia after HSCT, including thrombopoietin, interleukin-11, immunoglobulin, methylprednisolone and rituximab, are frequently unsatisfactory in platelet recovery. Therefore, it is urgent to explore an effective therapy to improve the outcomes of thrombocytopenia after HSCT. Thrombopoietin (TPO) is a cytokine that drives thrombopoiesis by stimulating the differentiation of stem cells into megakaryocytes and promoting megakaryocyte proliferation and polyploidization. Decitabine was approved for the treatment of myelodysplastic syndrome (MDS) as a DNA methylation inhibitors. Studies in vitro show that decitabine enhances platelet release and megakaryocyte maturation. Here, the investigators performed a prospective clinical trial, in order to investigate the safety and efficiency of rhTPO and decitabine in the treatment of thrombocytopenia following HSCT. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
