概括
在接受CAR-T治疗的大型B细胞淋巴瘤患者中,Levétiracetam (LVT) 预防措施没有减少免疫效应细胞相关的神经毒性综合征 (ICANS). 使用LVT与血液毒性增加有关,但没有改善生存结果.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 药理学 药理学是指药理学的学科.
背景情况:
- 卡特-T疗法,特别是抗CD19,为大B细胞淋巴瘤 (LBCL) 提供了有前途的治疗方法.
- 免疫效应细胞相关的神经毒性综合征 (ICANS) 是CAR-T疗法期间的一个重大问题,影响患者的结果.
- 列维 (LVT) 是作为一种预防药物来缓解ICANS.
研究的目的:
- 评估 levetiracetam (LVT) 预防在预防免疫效应细胞相关神经毒性综合征 (ICANS) 的有效性,在接受抗CD19 CAR-T治疗的大型B细胞淋巴瘤 (LBCL) 患者中.
- 评估LVT对ICANS发病率和严重性的影响,以及对其他不良事件和生存结果的影响.
- 确定LVT预防与改善的整体存活率 (OS) 和无进展存活率 (PFS) 有关.
主要方法:
- 一项对254名用抗CD19CAR-T疗法治疗的LBCL患者进行倾向性得分匹配的队列研究.
- 将接受LVT预防治疗的患者与未接受LVT预防治疗的患者进行比较,比例为1:1.
- 分析ICANS发病率和严重程度,免疫效应细胞相关血毒性 (ICAHT),总体存活率,无进展存活率和非复发性死亡率.
主要成果:
- 在任何等级ICANS (32.3%与37.1%,p=0.29) 或严重ICANS (等级2-4:15.1%与16.1%,p=0.80) 在LVT预防和无预防组之间发生的发生没有显著差异.
- 接受LVT预防的患者 (63.9%) 与没有接受LVT预防的患者 (37.3%,p<0.001) 相比,观察到与2-4级免疫效应细胞相关的血液毒性 (ICAHT) 的发生率显著更高.
- 总生存率 (p=0.337),无进展生存率 (p=0.670) 和非复发死亡率 (p=0.77) 在两组之间没有显著差异.
结论:
- 在接受CAR-T治疗的LBCL患者中,常规的 levetiracetam 预防不能有效降低ICANS的发生率或严重程度.
- LVT预防与免疫效应细胞相关的血液毒性风险增加有关.
- 需要进一步的研究来探索LVT在特定患者群体或ICANS后治疗中的潜在作用.

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein
448
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Combination Therapies and Personalized Medicine
5.1K
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...
