Celgene公布肾脏药sotatercept积极中期数据

2014-03-18 tomato 生物谷

生物技术公司Acceleron和合作伙伴新基(Celgene)公布了实验性肾脏病药物sotatercept一项正在开展的IIa期研究的中期数据。 该IIa期临床试验是一项随机、安慰剂对照、单剂量和多剂量、剂量递增研究,在正接受血液透析治疗的终末期肾脏病(ESRD)患者中开展,旨在评估sotatercept用于纠正(correction)ESRD患者贫血(anemia)的药代动力学、安全性、疗效、

生物技术公司Acceleron和合作伙伴新基(Celgene)公布了实验性肾脏病药物sotatercept一项正在开展的IIa期研究的中期数据。

该IIa期临床试验是一项随机、安慰剂对照、单剂量和多剂量、剂量递增研究,在正接受血液透析治疗的终末期肾脏病(ESRD)患者中开展,旨在评估sotatercept用于纠正(correction)ESRD患者贫血(anemia)的药代动力学、安全性、疗效、耐受性和药效动力学。首个剂量组调查0.1mg/kg剂量的sotatercept皮下给药,后续剂量组调查0.3mg/kg、0.5mg/kg、0.7mg/kg剂量sotatercept皮下给药,研究中每4周给药一次,持续治疗8个周期,主要终点是药代动力学和安全性,次要终点包括血红蛋白和血清标志物对骨代谢的影响。

公布的数据来自于sotatercept 2个剂量(0.3mg/kg和0.5mg/kg)在首个28天给药周期中相对于安慰剂的安全性、药代动力学和血红蛋白数据。数据表明,单次给药后,安慰剂组、sotatercept 0.3mg/kg剂量组、0.5mg/kg剂量组,在首个28天周期中观察到的血红蛋白变化峰值分别为0.1克/升、0.5克/升、0.8克/升。不良反应多为轻至中度,与sotatercept无关,并于患者病史基本一致。研究中,未观察到剂量依赖的血压变化。

该项中期分析的详细数据将提交至4月22-26日在内达华州举行的国家肾脏基金会2014春季临床会议

在2013年12月,Celgene启动了sotatercept用于治疗终末期肾脏病(ESRD)的第2个II期临床试验。该II期试验是一项2部分研究,旨在评估sotatercept治疗贫血和潜在控制慢性肾脏病矿物质和骨代谢异常(CKD-MBD)不良现象的安全性和疗效。

Acceleron公司目前有三个药物正处在II期临床开发--sotatercept,ACE-536 和 dalantercept。其中前2种药物都是与Celgene公司合作开发用于治疗地中海贫血和骨髓异常增生综合征,dalantercept则开发用于抑制肿瘤中的血管增生。

关于Sotatercept

Sotatercept是一种活化素(activin)受体IIA型融合蛋白,作为转化生长因子β(TGF-β)家族成员的一种配体陷阱(ligand trap)发挥作用。TGF-β家族成员参与红细胞生成(erythropoiesis)。Sotatercept调节晚期红细胞前体细胞的分化和成熟,其独特作用机制与促红细胞生成素(EPO)截然不同,EPO刺激早期红细胞前体细胞的分化。

目前,新基(Celgene)和Acceleron制药正在联合开发sotatercept,该药正处于多个II期临床试验。
