Abstract:
Objective:To evaluate the safety and efficacy of eltrombopag combined with immunosuppressive therapy in patients with aplastic anemia (AA) in China.Methods:We investigated and analyzed the clinical data of AA patients from 14 hematological treatment centers who were treated with oral eltrombopag for at least 3 mon.Results:We enrolled 56 AA patients, including 19 treatment-na?ve patients and 37 IST-refractory patients. The median administration period for eltrombopag was 7 (3-31) months, and the median maximum stable dosage was 75 mg/d (50-150 mg/d) . The 3-month hematological response (HR) rate was 60%, and the complete response (CR) rate was 30% in 10 SAA patients who were treated with first-line eltrombopag and standard IST (ATG+CsA) . Eight of 9 eltrombopag and CsA ± androgen first-line treated SAA patients responded (8/9, 89%) and 4 (44%) gave CR. The overall HR and CR rates were 79% and 52.6%, respectively, among these 19 patients by the end of the follow-up period. Of the 19 AA patients who were refractory to CsA ± androgen, 11 achieved HR (57.9%) at 3 mon, and the best HR rate was 44% in standard IST (ATG+CsA) refractory 18 patients after eltrombopag treatment. Fifty-one percent of the patients experienced mild or moderate adverse events, and gastrointestinal discomfort was the most common adverse effect reported by the study subjects.Conclusion:Adding Eltrombopag in first-line IST can accelerate the acquisition and improve the quality of hematological responses in AA patients. AA with relatively more residual hematopoietic cells may be well treated with eltrombopag and non-ATG IST. Eltrombopag can be used as salvage therapy for CsA±androgen refractory patients. Eltrombopag was generally safe and well tolerated by AA patients in China.
