概括
两种个性化癌症疫苗,瘤溶解酸 (TL) 和mRNA-4157,对晚期黑色素瘤有希望. 这种TL疫苗证明了较少不良事件的改善无疾病生存率,而mRNA-4157也改善了无复发生存率.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 疫苗学 疫苗学 疫苗学
背景情况:
- 检查点抑制剂 (CPI) 改善了黑色素瘤存活率,但有效性有限,复发率约为50%.
- 可变的CPI反应需要新的策略,如癌症疫苗,以提高抗瘤免疫力.
研究的目的:
- 为了比较两项针对晚期黑色素瘤的个性化治疗癌症疫苗试验:Elios Therapeutics的瘤溶解酸 (TL) 疫苗和Moderna的mRNA-4157疫苗.
- 评估这些新型辅助黑色素瘤疗法之间的疗效,安全性和生产差异.
主要方法:
- 我们比较了2b期随机试验:TL (双盲,安慰剂控制,n=187) 和mRNA-4157 (开放标签,n=157).
- 这两种疫苗都旨在利用不同的平台刺激瘤特异性免疫反应:TL用酵母细胞壁颗粒,mRNA-4157用患者特异性新抗原.
- 分析了CPI组合,生产时间和不良事件概况的关键差异.
主要成果:
- 在36个月的时间里,TL疫苗显示了改善的无病生存率 (DFS) (HR=0.52,p<0.01).
- 在18个月的时间里,mRNA-4157疫苗证明了无复发生存率 (RFS) 的改善 (HR=0.56,p=0.053).
- 与mRNA-4157 (12%) 相比,TL疫苗的3级不良事件明显较低 (<1%).
结论:

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Tumor Immunotherapy
667
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
