About

Aplastic anemia (AA) is a group of clinical syndromes. Treatment options are very limited. The results of a previous clinical study showed good efficacy and a high safety profile of herombopag in improving thrombocytopenia, but this result needs to be supported by more data.

In our study, patients who were willing to participate in this study and were diagnosed with transfusion-dependent non-heavy aplastic anemia were randomized to the rhTPO combined with herombopag + cyclosporine group and given rhTPO (at a dose of 1500 U by subcutaneous injection once daily for 7 d, 28 d for 3 courses) +Herombopag(10 mg/day for 3 months) + cyclosporine (3-5 mg/kg/d for 3 months). -5 mg/kg/d for at least 6 months) and herombopag + cyclosporine (10 mg/day for 3 months) + cyclosporine (3-5 mg/kg/d for at least 6 months) in the herombopag+ cyclosporine group to observe the efficacy and safety.

Full description

Aplastic anemia (AA) is a group of clinical syndromes caused by a significant decrease in bone marrow hematopoietic tissue from different etiologies, resulting in hematopoietic failure. The prevalence of AA in China is 7.4 per 1 million. It peaks in the 15-25 and 60+ age groups and is more common in men than women. Treatment options are very limited. The results of a previous clinical study showed good efficacy and a high safety profile of herombopag in improving thrombocytopenia, but this result needs to be supported by more data.

In our study, patients who were willing to participate in this study and were diagnosed with transfusion-dependent non-heavy aplastic anemia were randomized to the rhTPO combined with herombopag + cyclosporine group and given rhTPO (at a dose of 1500 U by subcutaneous injection once daily for 7 d, 28 d for 3 courses) +Herombopag(10 mg/day for 3 months) + cyclosporine (3-5 mg/kg/d for 3 months). -5 mg/kg/d for at least 6 months) and Herombopag + cyclosporine (10 mg/day for 3 months) + cyclosporine (3-5 mg/kg/d for at least 6 months) in the herombopag+ cyclosporine group to observe the efficacy and safety.
