我们使用来自疾病特异性诱导多能干细胞(iPSC)的运动神经元进行药物筛选,用于肌萎缩侧索硬化症(ALS),发现盐酸罗匹尼罗可预防运动神经元死亡。我们于2018年12月开始了一项在ALS患者中测试盐酸罗匹尼罗的随机临床试验。这是一项I/IIa期随机、双盲、安慰剂对照、单中心、开放标签持续临床试验。主要目的是评估盐酸罗匹尼罗在ALS患者中的安全性和耐受性。次要目标包括以下有效性评估:ALSFRS-R、手持式测力计定量肌肉力量、CT扫描肌肉体积、用力肺活量、活动跟踪器体力活动、生存率、ALSAQ 40量表和Zarit护理人员负担访谈。此外,我们将使用受试者来源的iPSC/运动神经元进行疗效评价,并评估血浆/CSF生物标志物(TDP-43和ALS相关RNA/microRNA)作为探索性研究问题。盐酸罗匹尼罗可能靶向ALS病理学的多种机制(即氧化应激、线粒体功能障碍和代表ALS表型的TDP-43/FUS蛋白的异常聚集),基于iPSC研究的临床前研究结果前景广阔。这种药物的可用性表明,快速转化为日常临床使用是可能的。我们的试验将为进一步的潜在试验提供可靠和重要的数据。结果将于2021年3月公布。
We performed drug screening using motor neurons derived from disease-specific induced pluripotent stem cells (iPSCs) for amyotrophic lateral sclerosis (ALS) and found that ropinirole hydrochloride prevented motor neuron death. We have started a randomized clinical trial testing ropinirole hydrochloride in ALS patients in December 2018. This is a phase I/IIa randomized, double-blind, placebo-controlled, single-center, open-label continuation clinical trial. The primary aim is to assess the safety and tolerability of ropinirole hydrochloride in patients with ALS. Secondary aims include the following effectiveness evaluations: ALSFRS-R, quantitative muscle strength by a hand-held dynamometer, muscle volume by CT scan, forced vital capacity, physical activity by an activity tracker, survival, ALSAQ40 scale, and a Zarit Caregiver Burden Interview. Moreover, we will perform an efficacy evaluation using subjects-derived iPSCs/motor neurons and assess plasma/CSF biomarkers (TDP-43, and ALS-related RNA/micro RNA) as exploratory research questions. Ropinirole hydrochloride potentially targets multiple mechanisms of ALS pathology (ie, oxidative stress, mitochondrial dysfunction, and abnormal aggregation of TDP-43/FUS protein, which is representative of the ALS phenotype), with promising preclinical study results based on iPSC research. The availability of the drug suggests that rapid translation to daily clinical use might be possible. Our trial will provide reliable and important data for further potential trials. The results will appear in March 2021.
