概括
将索拉费尼布添加到多克索鲁比辛,显著改善了晚期肝细胞癌 (HCC) 患者的治疗结果. 与单独使用多克索鲁素相比,这种组合治疗显示出更长的无进展和整体存活时间.
科学领域:
- 肝细胞癌研究 肝细胞癌研究
- 瘤学 药物开发 药物开发
- 临床试验分析
背景情况:
- 索拉菲尼布 (400毫克每天两次) 曾在先进的肝细胞癌 (HCC) 患者中表现出生存益处.
- 一项第一阶段研究表明,索拉费尼布与多克索鲁比 (60 mg/m2) 结合在耐火固体瘤患者中耐受性良好.
- 在之前的2期或3期试验中,索拉芬尼和多克索鲁比辛的组合在晚期HCC患者中没有被评估.
研究的目的:
- 评估将多克索鲁比辛与索拉费尼布结合治疗的疗效和安全性,与多克索鲁比辛单一治疗相比.
- 为了比较诊断为晚期HCC和Child-Pugh A肝功能的患者的治疗结果.
主要方法:
- 一项双盲,跨国阶段2研究招募了96名先前未接受过治疗的患有晚期HCC (Child-Pugh A) 的患者.
- 患者被随机分配,每21天接受静脉注射多克索鲁比 (60毫克/米2),再加上口服索拉费尼布 (400毫克每天两次) 或安慰剂.
- 主要终点是进展的时间,通过独立审查确定.
主要成果:
- 该研究因临时有效性分析而提前停止.
- 索拉芬尼布-多克索鲁比辛组的中位时间明显较长 (6.4个月),相比于多克索鲁比辛-安慰剂组 (2.8个月;P = .02).
- 综合疗法也显著改善了中位总生存时间 (13.7 vs 6.5 个月; P = .006) 和无进展生存时间 (6.0 vs 2.7 个月; P = .006). 毒性概况与单剂使用可比.
结论:
- 索拉菲尼布和多克索鲁比的组合显著改善了晚期HCC患者的进展时间,整体存活率和无进展存活率.
- 索拉菲尼布和多克索鲁比之间的潜在协同效应需要进一步研究.
- 这种组合尚未用于高级HCC的常规临床实践.

Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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.
