我们的实验室之前利用散发性和家族性 ALS 患者制备的诱导多能干细胞 (iPSC) 建立了脊髓运动神经元 (MN),并成功重现了疾病特异性的病理生理过程。接下来,我们利用 1232 种现有化合物的药物库寻找能够减缓 ALS 进展的有效药物,并发现盐酸罗匹尼罗可预防 MN 死亡。 2018年12月,我们启动了一项由研究者发起的临床试验,在 ALS 患者中测试盐酸罗匹尼罗缓释片。这是一项正在进行的 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 (UMIN000034954)。主要目的是评估盐酸罗匹尼罗对 ALS 患者的安全性和耐受性。我们还将使用患者来源的 iPSC/MN 进行疗效评估。主要纳入标准如下: 1)根据ALS诊断标准(El Escorial修订版)且发病后60个月内,“临床可能且实验室支持的ALS”、“临床可能的ALS”或“临床明确的ALS”; 2) 12 周磨合期内 ALSFRS-R 评分变化为 2 至 5 分。最后,15 名患者将被分配到活性药物组,5 名患者将被分配到安慰剂组。我们的试验将成为基于 iPSC 的药物开发策略的试金石试验。
Our laboratory previously established spinal motor neurons (MN) from induced-pluripotent stem cells (iPSCs) prepared from both sporadic and familial ALS patients, and successfully recapitulated disease-specific pathophysiological processes. We next searched for effective drugs capable of slowing the progression of ALS using a drug library of 1232 existing compounds and discovered that ropinirole hydrochloride prevented MN death. In December 2018, we started an investigator-initiated clinical trial testing ropinirole hydrochloride extended-release tablets in ALS patients. This is an on-going phase I/IIa randomized, double-blind, placebo-controlled, single-center, open-label continuation clinical trial (UMIN000034954). The primary aim is to assess the safety and tolerability of ropinirole hydrochloride in patients with ALS. We will also perform an efficacy evaluation using patient-derived iPSCs/MN. Major inclusion criteria were as follows: 1)'clinically possible and laboratory-supported ALS','clinically probable ALS'or'clinically definite ALS', according to the criteria for the diagnosis of ALS (El Escorial revised) and within 60 months after disease onset; 2) change in ALSFRS-R score of-2 to-5 points during the 12-week run-in period. Finally, 15 patients will be assigned to the active drug and 5 patients to the placebo. Our trial will be a touchstone trial for iPSC-based drug development strategies.
