- 评估杜尔瓦卢马布加化疗对整体存活时间 (OS) 的影响,与安慰剂加化疗相比.
- 分析二次终点,包括无进展生存率 (PFS),客观反应率 (ORR) 和安全概况.
主要方法:
- 一项第三阶段,双盲,安慰剂对照研究 (TOPAZ-1试验) 涉及685名以前未经治疗,无法切除或转移的BTC患者.
- 患者被随机分配1:1接受杜尔瓦卢马布或安慰剂,结合吉姆西塔丁和西斯普拉丁,长达8个周期.
- 治疗后是杜尔瓦卢马布或安慰剂单一治疗,直到疾病进展或不可接受的毒性,以OS作为主要终点.
主要成果:
- 与安慰剂相比,杜尔瓦卢马布加化疗显示总体生存率 (危险比率:0.80,P=0.021) 显著改善.
- 使用杜尔瓦卢马布,无进展生存率也显著改善 (危险比率:0.75,P=0.001).
- 杜尔瓦卢马布组的客观反应率 (26.7%) 与安慰剂组 (18.7%) 相比较高,3级或4级不良事件的发生率相似.
结论:
- 杜尔瓦卢马布与格姆西塔宾加西斯普拉丁结合,为晚期胆道癌症患者提供显著的生存益处.
- 添加杜瓦卢马布可以改善关键的疗效终点,包括PFS和ORR,而不会影响安全性.
- 这种组合代表了先进的BTC有前途的新一线治疗选择,解决了长期未满足的医疗需求.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Tumor Immunotherapy
526
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.
