简要总结

This is a multicenter, prospective, randonmized study. Our previous retrospective study showed that for SAA patients who were intolerant to ATG, CsA+ eltrombopag (EPAG) had similar efficacy to CsA+ATG+EPAG. Since the action mechanism of AVA and EPAG is not exactly the same, and the metabolic level of the elderly is not the same as that of younger patients, it is unknown whether there are predictive factors of efficacy in the treatment of AVA. We wondered whether CsA+AVA could achieve an efficacy similar to CsA+ATG+AVA in the Elderly. Meanwhile, to explore the predictive factors of efficacy, to find out a safe and effective treatment strategy for the Elderly.

详细描述

Aplastic anemia (AA) can be divided into severe AA (SAA) and non-severe AA (NSAA), according to the severity of the disease. For SAA patients with o condition of hematopoietic stem cell transplantation, guideline recommended ciclosporin A (CsA) + anti-thymocyte immunoglobulin (ATG) + thrombopoietin receptor agonists (TPO-RA) as the first-line therapy. Our previous retrospective study showed that for SAA patients who were intolerant to ATG, CsA+ eltrombopag (EPAG) had similar efficacy to CsA+ATG+EPAG. However, the adverse effects such as hepatotoxicity and gasrointestinal disorder limit its application in elderly SAA.Compared with EPAG, AVA has no hepatotoxicity and less other adverse effects, but there was few studies for AA. Our previous study demonstrated that AVA was effective in 55% of refractory AA. Since the action mechanism of AVA and EPAG is not exactly the same, and the metabolic level of the elderly is not the same as that of younger patients, it is unknown whether there are predictive factors of efficacy in the treatment of AVA. Thus, we wondered whether CsA+AVA could achieve an efficacy similar to CsA+ATG+AVA in the Elderly.
