概括
隆卡斯图克西马布特西林 (lonca) 显示,在仿制抗原受体T细胞治疗 (CAR-T) 后,在复发性/耐药性扩散性大B细胞淋巴瘤 (DLBCL) 中具有有效性. 这项现实研究证实了Lonca是CAR-T治疗进展的患者的可行治疗选择.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
背景情况:
- 化学抗原受体T细胞疗法 (CAR-T) 是对复发性或耐火性 (R/R) 扩散性大B细胞淋巴瘤 (DLBCL) 的重大进展.
- 在CAR-T失败后后续疗法的有效性仍然是一个重要的临床问题.
研究的目的:
- 为了评估loncastuximab tesirine (lonca) 单疗法在R/R DLBCL患者中前期CAR-T治疗进展或失败的真实世界的疗效.
- 在这个患者群体中评估lonca治疗后的响应率,响应持续时间 (DOR),无进展生存率 (PFS) 和整体生存率 (OS).
主要方法:
- 在美国对118名R/R DLBCL成年患者进行了回顾性分析,这些患者接受了lonca单疗法治疗.
- 患者在第二线 (2L) 或第三线 (3L) CAR-T治疗进展后,分别接受了lonca作为第三线 (3L) 或第四线 (4L) 治疗.
- 分析的结果包括整体响应率 (ORR),完整响应率 (CR),DOR,PFS和OS.
主要成果:
- 在3L lonca组 (在2L CAR-T之后) 中,ORR为73% (34%CR),12个月DOR,PFS和OS率分别为68%,77%和84%.
- 在4L lonca组 (在3L CAR-T之后) 中,ORR为78% (17% CR),中位数DOR为7.6个月,中位数PFS为12.0个月,12个月的OS为95%.
- 在3L小组中没有达到中位数的DOR,PFS和OS,随访时间中位数为8.5个月.
结论:
- 伦卡斯图西马布特西林单疗法在R/R DLBCL患者中显示出显著的疗效,这些患者在CAR-T治疗后复发.
- 对于R/R DLBCL患者来说,Lonca在第三和第四线设置中是一个有价值的治疗选择,包括那些对CAR-T耐药或在CAR-T后进展的患者.

Tumor Immunotherapy
480
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.

Targeted Cancer Therapies
7.5K
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.
