钾结合剂ZS-9可降低高钾血症复发(HARMONIZE试验)

2014-09-29 清热解毒2号 丁香园

近日,ZS制药公司发布的钾结合剂硅酸锆复合物(ZS-9)III期试验初步研究结果显示,每日3种剂量(5g、10g、15g)的ZS-9均可降低高钾血症28天的复发率。 HARMONIZE试验纳入了258例与慢性肾脏病(CKD)、心力衰竭(HF)、糖尿病和/或阻断血管紧张素醛固酮系统(RAAS)药物有关的高钾血症患者。 该试验包括开放标签期和随机期,在开放标签阶段,高钾血症患者接受ZS-9每日10

近日,ZS制药公司发布的钾结合剂硅酸锆复合物(ZS-9)III期试验初步研究结果显示,每日3种剂量(5g、10g、15g)的ZS-9均可降低高钾血症28天的复发率。

HARMONIZE试验纳入了258例与慢性肾脏病(CKD)、心力衰竭(HF)、糖尿病和/或阻断血管紧张素醛固酮系统(RAAS)药物有关的高钾血症患者。

该试验包括开放标签期和随机期,在开放标签阶段,高钾血症患者接受ZS-9每日10g、一日三次持续48小时的治疗,监测血钾下降的速度和幅度;随后,血钾正常(K+水平3.5-5.0mmol/L)的患者随机分配至药物组(5g、10g、15g,每日一次)或安慰剂组持续28天,主要终点比较了ZS-9和安慰剂在第8天和28天间隔期间的平均血清钾水平。

完成初始28天治疗的患者将进入另一个开放标签试验(ZS004)。

高钾血症是部分RAAS阻滞药物常见的副作用,对心律失常和心源性猝死均有不同程度的影响,而高钾血症也可妨碍RAAS阻滞药物的完全使用。

HARMONIZE研究作为一项随机双盲安慰剂对照试验显示,该药的副作用与其它对ZS-9的临床研究相似。而近期的部分其它试验显示ZS-9的安全性与安慰剂相当,对服用RAA抑制药物的心力衰竭亚组患者的分析显示,该药可降低血清钾并维持血钾水平,不会导致低钾血症。

该研究的首席研究员、来自圣卢克中部美国心脏研究院的Mikhail Kosiborod将在美国心脏协会会议上报告该研究的详细数据。

该公司表示计划在2015年上半年对美国FDA提出新药申请,同时对欧洲药品管理局申请上市许可。
