GPX-002 is currently being developed using the same construct for the treatment of both Type 1 diabetes (T1D) and Type 2 diabetes (T2D). The same general novel approach is used in each of T1D and T2D whereby an adeno-associated virus (AAV) vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, this can be done with a routine endoscopy procedure. In T1D, GPX-002 is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, wh ...

文章核心观点 - 公司研究合作者将在2025年美国癌症研究协会年会上展示其领先候选药物Reqorsa®基因疗法治疗KRASG12C突变非小细胞肺癌的积极临床前数据,该疗法有望成为Ras抑制剂耐药肺癌的潜在治疗方法 [1][2] 公司动态 - 公司研究合作者将在2025年4月25 - 30日于伊利诺伊州芝加哥举行的美国癌症研究协会年会上,展示领先候选药物Reqorsa®基因疗法治疗KRASG12C突变非小细胞肺癌的积极临床前数据 [1] - 公司总裁兼首席执行官表示学术合作伙伴展示的临床前数据进一步验证了Reqorsa作为多种癌症潜在治疗方法的有效性,对TUSC2在肺癌治疗中的作用和临床前项目感到鼓舞 [2] - 公司鼓励感兴趣的投资者和股东通过访问公司网站、注册电子邮件提醒以及在社交媒体上关注公司来获取新闻稿和行业更新 [9] 研究内容 海报信息 - 海报标题为“通过TUSC2基因疗法克服KRASG12C突变非小细胞肺癌对索托拉西布的获得性耐药”,属于“实验与分子治疗”类别,在“分子靶向治疗中的耐药性3”会议中展示,时间为4月29日下午2 - 5点CT,地点在海报区17,海报板编号为12,摘要展示编号为5517 [3] 研究背景 - 首款FDA批准的KRAS抑制剂Lumakras®(索托拉西布)的获得性耐药是治疗KRASG12C突变非小细胞肺癌的重大挑战,患者最终会产生耐药性,需要替代治疗策略,耐药机制包括KRAS基因出现额外突变、KRAS通路重新激活或替代信号通路激活 [3] 研究结果 - TUSC2基因疗法(Reqorsa)能有效克服KRASG12C突变非小细胞肺癌小鼠异种移植模型中索托拉西布的获得性耐药 [3] - TUSC2转染显著减少了两个获得性耐药细胞系的集落形成,也显著增加了获得性耐药细胞的凋亡,将TUSC2重新表达于获得性耐药的患者来源肿瘤类器官中,与空载体相比,显著降低了类器官的活力 [4] - H23AR肿瘤对索托拉西布的敏感性明显低于其亲本肿瘤,但Reqorsa治疗在控制肿瘤生长方面比单独使用索托拉西布或对照组更有效,Reqorsa单独使用对TC314AR患者来源异种移植瘤也有很强的抗肿瘤作用,索托拉西布单独使用在这些模型中无显著抗肿瘤活性,而Reqorsa与索托拉西布联合治疗TC314AR患者来源异种移植瘤时观察到协同抗肿瘤效应 [4] - 研究表明Reqorsa单独或与索托拉西布联合使用,可诱导凋亡、抑制集落形成,并在KRASG12C突变的索托拉西布获得性耐药异种移植瘤和患者来源异种移植瘤中显示出显著的抗肿瘤疗效 [5] 产品介绍 Reqorsa®基因疗法 - Reqorsa(quaratusugene ozeplasmid)由包含TUSC2基因的质粒封装在非病毒脂质纳米颗粒中以脂质复合物形式(公司的Oncoprex®递送系统)组成,带正电荷,通过静脉注射,特异性靶向癌细胞,旨在将功能性TUSC2基因递送至带负电荷的癌细胞,同时减少正常组织摄取 [6] - MD安德森进行的实验室研究表明,Reqorsa治疗后,体外肿瘤细胞对TUSC2的摄取是正常细胞的10至33倍 [7] 公司产品管线 - 公司是临床阶段的基因疗法公司,专注为癌症和糖尿病患者开发改变生活的疗法,其技术旨在输送抗病基因,为目前治疗选择有限的大量癌症和糖尿病患者提供新疗法 [8] - 公司肿瘤学项目利用其全身性非病毒Oncoprex®递送系统,将表达基因的质粒封装在脂质纳米颗粒中以脂质复合物形式存在,产品通过静脉注射,被肿瘤细胞摄取后表达肿瘤中缺乏的抑癌蛋白 [8] - 公司领先候选产品Reqorsa®基因疗法正在两项临床试验中评估用于治疗非小细胞肺癌和小细胞肺癌,每个肺癌临床项目都获得了FDA的快速通道指定,小细胞肺癌项目还获得了FDA孤儿药指定 [8] - 公司糖尿病基因疗法采用新型输注过程,使用AAV载体将Pdx1和MafA基因直接递送至胰腺,在1型糖尿病模型中,GPX - 002将胰腺中的α细胞转化为功能性β样细胞,可产生胰岛素且可能与β细胞不同以逃避人体免疫系统,在2型糖尿病中,GPX - 002被认为可使耗尽的β细胞恢复活力和补充 [8]
