J Clin Invest:抗硬骨素单克隆抗体对HPP治疗的有效性及安全性评估

2017-04-28 MedSci MedSci原创

背景:低磷酸血症(HPP)是一种罕见的遗传性疾病,导致ALPL基因突变引起的骨形成和矿化的变化,编码组织非特异性碱性磷酸酶(ALP)酶。

背景:低磷酸血症(HPP)是一种罕见的遗传性疾病,导致ALPL基因突变引起的骨形成和矿化的变化,编码组织非特异性碱性磷酸酶(ALP)酶。

方法:在本阶段IIA开放标签,单中心,患者内,剂量递增的研究中,成年的低磷酸血症HPP患者分别在第1,15和29天接受3次静脉注射逐渐增加剂量(5,10和20mg / kg)的 BPS804(一种完全人类抗硬化蛋白单克隆抗体药物)。患者在最后一次用药后接受为期16周的随访,我们在治疗和随访期间以指定的间隔评估了BPS804给药的药效学,药代动力学,初步疗效和安全性。

结果:8名患者(平均年龄47.8岁)参加了研究(6名女性,2名男性)。 BPS804在第2天和第29天之间使平均ALP和骨特异性ALP酶活性增加。骨形成标志物前胶原I型N-末端前肽(PINP),骨钙素和甲状旁腺激素的瞬时增加以及观察到I型胶原的骨吸收标记C-端肽(CTX-1)。第85天和研究结束时显示腰椎骨密度平均增加。治疗过程中有轻度短暂的不良反应。

结论:BPS804治疗耐受性良好,导致骨形成生物标志物和骨矿物质密度增加,表明可以应用硬皮蛋白抑制来增强HPP成人非危及生命的临床情况下的骨矿物质密度,稳定性和再生。
