Neurology:Preladenant单药治疗帕金森病III期失败

2017-05-11 zhangfan MedSci原创

III期结果表明,Preladenant不能作为单药用于帕金森病患者

近日研究人员公布了腺苷2A受体拮抗剂Preladenant作为非多巴胺能药物单药治疗帕金森病(PD)的临床结果。

在为期26周的III期研究中,确诊帕金森病5年以内的,未经左旋多巴或多巴胺激动剂治疗的,帕金森病指数(UPDRS)得分患者≥10以及赫恩分数≤3的患者,随机接受每天两次,每次2、5或10mg的Preladenant或1 mg雷沙吉兰(活性对照)或安慰剂。主要终点是26周的UPDRS得分变化。

研究招募1007人,Preladenant或雷沙吉兰26周均未表现出超越安慰剂的疗效,治疗组与安慰剂相比95%置信区间的差异性如下:2mg Preladenant 2.60, 5mg 1.30,10mg 0.40,雷沙吉兰1mg 0.30。事后分析没有确定一个单一的因果因素可以解释失败的试验的原因。Preladenant耐受性良好,少数患者因不良事件停药(Preladenant 7%, 雷沙吉兰3%,安慰剂 4%)

这项III期结果表明,Preladenant不能作为单药用于帕金森病患者。

帕金森氏病(PD)是一种可影响中枢神经系统的长期疾病。2017年4月,发表在《Sci Rep.》的一项网络Meta分析旨在确定目前用于PD治疗的现有药物的相对有效性。该研究对10种药物的有效性和耐受性进行比较。

Nat biotech:帕金森病治疗重大突破!星形胶质细胞重编程变身多巴胺神经元

黑质纹状体多巴胺能神经元死亡是帕金森病的一个重要病理特征之一。近日,来自瑞典卡罗林斯卡学院的研究人员寻找到一种新的帕金森病疗法。他们利用多种转录因子使大脑中的星形胶质细胞重编程为功能性多巴胺神经元。在帕金森模型小鼠体内,这种治疗方法成功改善了运动症状。

Pain:帕金森氏病患者对疼痛的反应机制变化

疼痛是帕金森病(PD)中的常见但仍被忽视的非运动性症状。然而,目前对PD中疼痛的神经机制知之甚少。近期,一项发表在Pain杂志上的研究探讨了PD中疼痛的高发率是否与功能障碍性疼痛控制下降有关。此项研究使用fMRI的方法,在21名PD患者(Hoehn&Yahr I-III)和23名健康对照者(HC)中感知和处理热疼痛期间评估了神经反应。 PD患者无使用多巴胺能药物,以避免混杂药物的影响。对
