评估 EN001 在 1A 型腓骨肌萎缩症患者中的安全性和有效性
一项开放、剂量递增、1b 期临床试验,旨在评估 EN001 在 1A 型腓骨肌萎缩症 (CMT1A) 患者中的安全性和有效性
研究概览
详细说明
该临床试验是一项1b期临床试验,采用3+3剂量递增设计,旨在评估EN001的安全性(包括耐受性)并探索疗效。
该研究设计采用传统的3+3剂量递增方法来确认最大耐受剂量(MTD)并确定推荐的2期剂量(RP2D)。
进行剂量增加,直到确认最大耐受剂量(MTD)为2.5×10^6细胞/kg(队列2)或更少,即最大计划剂量(MPD)。 最大耐受剂量(MTD)定义为剂量限制毒性(DLT)发生率低于33%的最高剂量。 为了确定最大耐受剂量(MTD),每个剂量组中招募 3-6 名测试受试者,EN001 每 4 周给药两次,并评估剂量限制毒性(DLT)直至 4 周(访视 6)。
安全审查委员会(SRC)由主要研究者、申办者等作为成员组成,并在每个队列结束时确认EN001(队列中最后一个给药受试者的剂量限制毒性结束(DLT)评估) 。 全面审查安全性数据,确定与剂量相关的所有事项,例如剂量的增加或减少,最终确定推荐的2期剂量(RP2D)。
此外,根据长期随访方案,参与1b期试验的受试者将从EN001给药时起进行为期5年的安全性和有效性随访。
