主要终点:Number Of Adverse Events related to the treatment · Evaluate the number of adverse event related to the treatment according to CTCAE V4.0 during the trial (including clinically significant changes in physical examination, radiographic images, safety lab tests, vital signs) · Up to 12 months after treatment administration (Day 0)
手术期间使用注射器向肿瘤或肿瘤切除部位给药,每剂含1×10^7或3×10^7个细胞。
这是一项I期临床试验,评估表达自杀基因的研究性异体骨髓间充质干细胞疗法MSC11FCD用于新诊断胶质母细胞瘤患者的安全性、耐受性和最大耐受剂量。研究产品在手术切除后瘤内给药。本研究旨在探索MSC11FCD能否在术后阶段提供局部靶向治疗,以处理残余肿瘤细胞并降低早期复发风险。
This is a phase I clinical trial evaluating the safety, tolerability, and maximum tolerated dose of MSC11FCD, an investigational allogeneic bone marrow-derived mesenchymal stem cell therapy expressing a suicide gene, in patients with newly diagnosed glioblastoma. The investigational product is administered intratumorally following surgical resection. This study aims to explore whether MSC11FCD can provide a targeted, localized treatment option during the postsurgical period, potentially addressing residual tumor cells and reducing early recurrence.
