概括
这项研究研究了纳米颗粒蛋白结合帕克利塔塞尔 (nab-paclitaxel) 与PD-1抑制剂在高级软组织肉瘤 (STSs). 该组合显示了适度的活性和轻度的毒性,在接受更少先前化疗线的患者中,结果更好.
科学领域:
- 在瘤学瘤学.
- 医学研究 医学研究
- 临床试验 临床试验
背景情况:
- 转移性软组织肉瘤 (STSs) 存在治疗挑战.
- 在先进的STS中,将纳米粒子与蛋白结合的帕克利塔塞尔 (nab-paclitaxel) 与PD-1抑制剂相结合的疗效仍然不确定.
- 以前的化疗失败需要探索新的治疗策略.
研究的目的:
- 评估NAB-PACLITAXEL加CAMRELIZUMAB (一种PD-1抑制剂) 在晚期STS患者的安全性和疗效.
- 评估这种组合治疗的客观反应率 (ORR) 和无进展生存期 (PFS).
- 确定可能从这种治疗方案中获益更多的患者子组.
主要方法:
- 进行了一项单中心,开放标签,单臂II期临床试验.
- 前期化疗失败的40名晚期STS患者接受了nab-paclitaxel和camrelizumab.
- 治疗涉及多达六个周期的组合疗法,用camrelizumab持续长达一年. 评估了PFS,ORR和安全性.
主要成果:
- 总体客观应答率 (ORR) 为22.5%,中位数无进展生存期 (PFS) 为1.65个月.
- 患有表皮性肉瘤的患者表现出更长的PFS趋势,尽管在统计学上并不显著.
- 在接受仅一线先前化疗 (2.8个月) 的患者中,与两条或更多线 (1.3个月,p=0.046) 的患者相比,观察到显著更长的PFS.
结论:
- 纳布-帕克利塔塞尔加上卡姆雷利祖马布在晚期STS中表现出温和的临床活性和轻度毒性,特别是在上皮状肉瘤,血管肉瘤和纤维肉瘤中.
- 先进的STS的整体有效性相对较低,这表明需要进一步调查.
- 未来的研究应该探索将nab-paclitaxel与其他药物结合使用,包括化疗和向疗法,用于特定的STS亚型.

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.
