概括
双特异性抗体 (BsAb) 与多发性骨髓瘤患者的严重感染风险较高,与仿真抗原受体T细胞疗法 (CAR-T) 或抗体-药物结合物 (ADC) 相比. 这种与BsAb相关的风险增加在低甘球蛋白血症期间尤为明显.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 血液学 血液学 血液学
背景情况:
- 针对B细胞成熟抗原 (BCMA) 的疗法在多发性骨髓瘤中显示出有效性.
- 感染是与这些先进治疗方法相关的重大挑战.
- 了解不同BCMA向模式的比较感染风险至关重要.
研究的目的:
- 评估和比较BCMA向的仿真抗原受体T细胞疗法 (CAR-T),双特异抗体 (BsAb) 和抗体-药物结合物 (ADC) 后的传染性并发症.
- 为了确定特定的患者群体或与较高的感染风险相关的疾病.
主要方法:
- 对256名多发性骨髓瘤患者进行了回顾性单中心分析.
- 患者接受了CAR-T (n=92),BsAb (n=55) 或ADC (n=109) 的治疗.
- 主要终点:严重 (等级≥3) 感染的发病率;二次分析包括在低血和中性衰竭期间的比较.
主要成果:
- 与CAR-T (26%) 和ADC (8%) 相比,BsAb (40%) 观察到严重感染的发生率更高.
- 此外,BsAb的5级感染率 (7%) 与CAR-T和ADC (0%) 相比较高.
- 一年后,CAR-T显示严重感染的发病率明显低于BsAb (IRR=0.43). 与CAR-T相比,BsAb接受者在低血糖球蛋白血症期间出现更高的感染率,在非中性质衰竭期间风险增加.
结论:
- 与CAR-T和ADC相比,双特异性抗体与多发性髓瘤中严重感染的更高和更持久的风险有关.
- 感染的风险是高的与BsAb在低血糖球蛋白血症和CAR-T在中性质衰竭期间.
- 这些发现凸显了需要针对特定的BCMA向治疗量身定制的警感染监测和管理策略的需要.

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.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
