概括
塔拉塔马布在广泛的小细胞肺癌 (ES-SCLC) 实践中显示出更高的细胞因子释放综合征 (CRS) 和免疫效应细胞相关的神经毒性综合征 (ICANS). 预防性托西利祖马布在高风险患者中可以减少这些毒性.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 临床药理学 临床药理学
背景情况:
- 塔拉塔马布是一种针对DLL3的双特异性T细胞参与剂,已被批准用于扩散阶段小细胞肺癌 (ES-SCLC) 的二线治疗.
- 尽管有希望的临床试验疗效,但tarlatamab的真实安全数据,特别是关于细胞因子释放综合征 (CRS) 和免疫效应细胞相关的神经毒性综合征 (ICANS) 的数据有限.
研究的目的:
- 评估tarlatamab在患有SCLC或高级神经内分泌癌的患者中的真实安全性.
- 确定CRS和ICANS的预测因子,并评估预防性托西利祖马布对这些不良事件的影响.
主要方法:
- 对40名用tarlatamab治疗的患者进行了回顾性分析.
- 对临床,实验室和与治疗相关的变量进行审查,包括CRS和ICANS.
- 在不接受预防性托西利祖马布的患者中使用Firth逻辑回归进行毒性预测模型的开发.
主要成果:
- 在30名没有接受预防性托西利祖马布治疗的患者中,53.3%的患者在循环1日后出现了CRS,23.3%的患者在循环1日后出现了ICANS;10%的患者每人均经历了≥3级的严重程度.
- 乳酸脱酶 (LDH) 和肝转移的升高预测了CRS;LDH也预测了≥2级CRS.
- 糖尿病和心血管疾病与ICANS有关;预防性托西利祖马布似乎减少了CRS和ICANS发生率.
结论:
- 与临床试验相比,Tarlatamab在现实环境中与更高的CRS和ICANS率有关.
- 预防性托西利祖马布可以减轻高风险患者的CRS和ICANS,因此应考虑将其纳入治疗方案.

Tumor Immunotherapy
1.8K
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.

Treatment Resistant Cancers
3.7K
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
8.6K
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.
