概括
在转移性非小细胞肺癌 (NSCLC) 中,在先前免疫疗法和化疗后,阿特佐利祖马布加卡博赞提尼布与多塞塔塞尔相比没有改善整体存活率. 这种组合在这个患者群体中显示出与多塞塔克塞尔类似的安全性.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 医学瘤学 医学瘤学
背景情况:
- 检查点抑制剂已成为非小细胞肺癌 (NSCLC) 的先进一线治疗方法.
- 在抗PD-L1/PD-1免疫疗法和基化疗后进展的转移性NSCLC患者中,存在重大未满足的需求.
- 在CONTACT-01试验中,研究了这种耐火患者组的新型治疗策略.
研究的目的:
- 在转移性NSCLC的患者中,评估阿特佐利祖马布加卡博赞提尼布与多塞塔克塞尔的疗效和安全性.
- 为了确定这种组合治疗是否改善了抗PD-L1/PD-1和化疗后进展的患者的整体生存期 (OS).
- 评估无进展生存 (PFS) 和安全结果.
主要方法:
- 一个多中心的,开放的,第三阶段的随机试验 (CONTACT-01,NCT04471428).
- 患者被分配1:1接受阿特佐利祖马布 (1,200毫克IV q3w) 加上卡博桑提尼布 (40毫克每天PO) 或多塞塔克塞尔 (75毫克/米2IV q3w).
- 主要终点是整体存活时间 (OS).
主要成果:
- 亚特佐利祖马布加卡博桑提尼布的中位寿命为10.7个月,而多塞塔克塞尔的平均寿命为10.5个月 (HR,0.88;P = .3668).
- 中位数PFS分别为4.6个月和4.0个月 (HR,0.74).
- 严重的不良事件和与治疗相关的3/4级AE在两支手臂之间是可比的;5级AE分别在7.6%和6.0%的患者中报告.
结论:
- 与dcetaxel相比,在转移性NSCLC患者中,atezolizumab加cabozantinib在抗PD-L1/PD-1和化疗后进展后没有显著改善整体存活率.
- 该组合的安全性概况与已知的阿特佐利祖马布和卡博桑提尼布的安全性概况一致.
- 可能需要进一步的研究来确定可能从这种联合治疗中受益的患者子组.

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.

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
