Disability affects approximately 50% of stroke survivors due to permanent loss of brain tissue. ReNeuron is testing the effectiveness of a unique stem cell product, called CTX, in disabled stroke patients. ReNeuron has developed CTX from human brain stem cells, with cell banks established to provide the large quantities needed for clinical use. The safety of CTX has been assessed in stroke-disabled patients in Scotland. Treatment of all patients in this Phase I clinical trial has been completed, with no reports to date of any serious side effects or worsening in disability in the patients. Sustained reductions in neurological impairment and spasticity have also been observed in most patients compared with their stable pre-treatment baseline performance. TSB support is needed to conduct a Phase II study in up to 41 patients with upper limb paralysis at 2-4 months after their strokes. This proposed clinical trial will determine if CTX produces clinically meaningful improvements in the use of the paralysed arm at 6 months post-treatment in a sufficient number of patients treated. Success in this project will represent a significant milestone for ReNeuron and for the wider stroke field.

由于脑组织永久性丧失，大约50%的中风幸存者会受到残疾的影响。ReNeuron正在测试一种名为CTX的独特干细胞产品在残疾中风患者中的有效性。ReNeuron已经从人脑干细胞中开发出CTX，并建立了细胞库，以提供临床所需的大量细胞。环磷酰胺的安全性已经在苏格兰中风残疾患者身上进行了评估。这项第一阶段临床试验中所有患者的治疗已经完成，到目前为止还没有任何报告显示患者有任何严重的副作用或残疾恶化。与稳定的治疗前基线表现相比，大多数患者的神经损害和痉挛状态也有持续的减少。需要TSB支持才能在多达41名中风后2-4个月的上肢瘫痪患者中进行II期研究。这项拟议的临床试验将确定CTX是否在治疗后6个月对足够数量的接受治疗的患者的瘫痪手臂的使用产生了临床上有意义的改善。该项目的成功将是ReNeuron和更广泛的中风领域的一个重要里程碑。
