  AX200(粒细胞集落刺激因子,G-CSF)是一种用于治疗急性卒中的候选药物,该药物涉及了一种新型、多模式急性病理生理和促进恢复的机制。Ⅱa期临床研究显示了在较大剂量范围内,AX200对卒中患者的安全性和耐受性。AXIS-2的主要研究目标是证明AX200与安慰剂相比对急性缺血性卒中患者的临床疗效。

  研究随机纳入了328例患者。主要入选标准为大脑中动脉(MCA)区域的缺血性卒中,在症状发生的9小时内进行治疗。受试者的基线NIHSS评分为6-22,年龄为18–85岁,初始梗死面积(MRI DWI)>15 ccm。对于接受重组组织型纤维蛋白酶原激活剂(rt - PA)治疗的患者,如果其溶栓后符合标准也被纳入。主要终点是90天后改良兰金量表(Rankin量表,MRS)的改善。次要终点是第90天的NIHSS的改善。进一步的疗效指标包括巴塞尔指数(Barthel指数,BI),梗死面积减少和死亡率。此外,研究还对细胞因子和安全参数进行了评价。研究已于2011年年底完成。
