Clinical Trial Summary

Bone marrow failure disease(BMFD) is a kind of bone marrow due to congenital or acquired hematopoietic stem cells (hemopoietic stem cell, HSC) function damage. Allogenic hemopoietic stem cell transplantation (Allo-HSCT) might be the most possible treatment to cure the disease.However, 5-26% of patients have been reported to have delayed platelet engraftment (DPE), which is defined as persistent severe thrombocytopenia (<20 × 109/L) for >35 days after transplantation . To date, no standard treatment and prevention has been recommended for DPE. In patients with DPE, the amount of transfusion, the increased risk of infection, and the prolonged average hospital stay were independent risk factors affecting the prognosis of allo-HSCT patients. Due to continuous and progressive failure in the bone marrow hematopoiesis, thrombocytopenia post HSCT is more common in BMFD patients and often achieves low response to conventional therapy, such as platelet transfusion. Therefore, it is of great significance to effectively promote hematopoietic reconstruction to improve the prognosis of transplant patients.

Description:

Bone marrow failure disease(BMFD) is a kind of bone marrow due to congenital or acquired hematopoietic stem cells (hemopoietic stem cell, HSC) function damage. Generally, BMFD can be divided into two categories based on pathogenesis, which is primary and secondary BMFD. The latter is commonly seen secondary to infection, cancer, drugs, while aplastic anemia(AA), myelodysplastic syndromes(MDS), paroxysmal nocturnal haemoglobinuria(PNH) and Fanconi anaemia(FA) are included in primary BMFD. Although immunotherapy or allogenic hemopoietic stem cell transplantation (Allo-HSCT) can be selected based on different individuals, allo-HSCT is still the most effective treatment for diseases that pose a greater threat to life or have a higher degree of malignancy, such as sereve aplastic anemia(SAA), MDS and PNH. Patients undergoing allo-HSCT typically achieve neutrophil and megakaryocyte reconstruction within 2 weeks and 3 weeks after transplantation respectively. However, 5-26% of patients have been reported to have delayed platelet engraftment (DPE), which is defined as persistent severe thrombocytopenia (<20 × 109/L) for >35 days after transplantation . To date, no standard treatment and prevention has been recommended for DPE. In patients with DPE, the amount of transfusion, the increased risk of infection, and the prolonged average hospital stay were independent risk factors affecting the prognosis of allo-HSCT patients. Due to continuous and progressive failure in the bone marrow hematopoiesis, thrombocytopenia post HSCT is more common in BMFD patients and often achieves low response to conventional therapy, such as platelet transfusion. Therefore, it is of great significance to effectively promote hematopoietic reconstruction to improve the prognosis of transplant patients.

Related Conditions & MeSH terms

• Bone Marrow Failure Disorders
• Stem Cell Transplant Complications

Intervention

Drug:
• Eltrombopag 25 MG Oral Tablet
Since thrombopoietin receptor agonists (TPO-RAs) have never been regularly used for promotion of cell engraftment post hematopoietic stem cell transplantation HSCT), we design this eltrombopag intervention to evaluate the safety and efficacy of TPO-RAs post HSCT.
• Supportive care
Patients receive transfusion of blood products, including platelets and red blood cells.
