胶质母细胞瘤(GBM)是成人最常见的原发性脑肿瘤,极易致死;接受标准治疗后,中位生存期仍不足两年。基于RNA的免疫疗法在为GBM等恶性脑肿瘤建立持久治疗应答方面具有显著潜力。与聚焦抗原的方法相比,RNA具有明显优势,但由于生物学稳定性差,通常无法直接给药。本综述聚焦RNA树突状细胞疫苗和RNA纳米颗粒疗法在GBM治疗中的应用。小型I期临床试验已显示RNA负载树突状细胞疫苗具有安全性;RNA负载纳米颗粒疫苗也即将在GBM患者中开展研究(NCT04573140)。
Glioblastoma (GBM) is the most common primary brain tumor in adults and is universally lethal with a median survival of less than two years with standard therapy. RNA-based immunotherapies have significant potential to establish a durable treatment response for malignant brain tumors including GBM. RNA offers clear advantages over antigen-focused approaches but cannot often be directly administered due to biological instability.
This review will focus on utilization of RNA dendritic cell vaccines and RNA nanoparticle therapies in the treatment of GBM. RNA-pulsed dendritic cell vaccines have been shown to be safe in a small phase I clinical trial and RNA-loaded nanoparticle vaccines will soon be underway in GBM patients (NCT04573140).
