Brief Summary:
Paroxysmal nocturnal hemoglobinuria is an acquired chronic hemolytic anemia,this study is designed to evaluate the safety and efficacy of Levamisole combined with cyclosporine A in patients with Subclinical Paroxysmal Nocturnal Hemoglobinuria and PNH in the setting of another bone marrow failure syndromes

Condition or disease Intervention/treatment Phase
Paroxysmal Nocturnal Hemoglobinuria Hemoglobinuria Hemoglobinuria, Paroxysmal Proteinuria Urination Disorders Thrombosis Bone Marrow Failure Aplastic Anemia, Anemia, Hemolytic Drug: Levamisole+cyclosporin A+Glucocorticoids Drug: cyclosporin A+Glucocorticoids Drug: Glucocorticoids Phase 2

Detailed Description:
Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal disorder of the hematopoietic stem cell characterized by intravascular hemolysis, hemoglobinuria, anemia, and thrombosis, Patients may be at high risk of thrombosis and may develop bone marrow failure or aplastic anemia, with low white blood cell and platelet counts,because the manifestation and pathologic processes are complicate,the treatment is very difficult,this study is designed to evaluate the safety and efficacy of Levamisole combined with cyclosporine A in patients with Subclinical Paroxysmal Nocturnal Hemoglobinuria and PNH in the setting of another bone marrow failure syndromes
