Early Prophylactic rhTPO Administration for Thrombocytopenia Associated With EAP Regimen-Based Hematopoietic Stem Cell Mobilization

This is a multicenter, prospective, single-arm, phase II clinical study evaluating the early prophylactic use of recombinant human thrombopoietin (rhTPO) to prevent thrombocytopenia associated with the EAP regimen for hematopoietic stem cell mobilization. The EAP regimen consists of etoposide, cytarabine, and pegylated granulocyte colony-stimulating factor (pegfilgrastim) and is used for hematopoietic stem cell mobilization before autologous stem cell transplantation in patients with multiple myeloma and B-cell lymphoma. Severe thrombocytopenia is a common complication during EAP-based stem cell mobilization and may increase the risk of bleeding and the need for platelet transfusions, and may sometimes delay stem cell collection. In this study, patients whose platelet counts decrease to ≤80 × 10⁹/L after EAP chemotherapy will receive rhTPO early as a preventive treatment. The study will evaluate whether early rhTPO administration can reduce the incidence of clinically significant bleeding and the need for platelet transfusion while maintaining adequate hematopoietic stem cell mobilization. The study will also monitor platelet counts, stem cell collection outcomes, and treatment-related adverse events to evaluate the effectiveness and safety of early rhTPO administration.

Comparison Study of EAP and Disease-Specific Chemotherapy Regimens in Hematopoietic Stem Cell Mobilization for Lymphoma

This study utilizes a prospective, multicenter, randomized two-arm design to evaluate the efficacy and safety of the etoposide, cytarabine, and pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) combination therapy (EAP regimen) in mobilizing hematopoietic stem cells in patients with non-Hodgkin's lymphoma (NHL). A total of 99 NHL patients will be enrolled as research subjects and will be randomly allocated in a 2:1 ratio to compare the EAP regimen versus disease-specific chemotherapy mobilization regimen. The primary endpoint is the proportion of patients achieving the ideal collection value after a single collection (CD34+ cells ≥5×10\^6/kg).

Clinical Study of rhTPO in Hematopoietic Stem Cell Mobilization for Autologous Transplantation in Acute Leukemia

Evaluation of the efficacy and safety of recombinant human thrombopoietin (rhTPO) at 300 U/kg/day for hematopoietic stem cell mobilization in autologous transplantation among acute leukemia patients

Comparison Study of EAP and CG Regimens for Mobilizing Hematopoietic Stem Cells in Multiple Myeloma Patients

This is a prospective, randomized, two-arm, multicenter, exploratory study aimed at evaluating the efficacy and safety of the combination of etoposide, cytarabine and Pegfilgrastim (EAP regimen) for mobilizing hematopoietic stem cells in patients with newly diagnosed multiple myeloma (NDMM). A total of 99 NDMM patients will be enrolled and randomly assigned to receive either the EAP regimen or the GC regimen (cyclophosphamide+ G-CSF) to mobilize hematopoietic stem cells. Subsequently, the mobilization effects and adverse reactions of all patients will be observed and compared.
