抗体-药物合物 (ADC) 的严重不良事件主要是由有效载荷对健康组织的影响驱动的,而不是与瘤相关的抗原. 分析每个ADC成分对于理解和减轻毒性风险至关重要.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
- 临床发展 临床发展
背景情况:
- 抗体-药物联合体 (ADCs) 是一种创新的治疗类别,它结合了抗体,有效载荷和链接器.
- 严重的不良事件 (SAE),特别是3级或更高的,往往导致ADC临床发展失败.
- 了解ADC毒性对于成功的治疗应用至关重要.
研究的目的:
- 分析已批准的ADC的毒性概况.
- 为了确定ADC安全性和组件特性 (抗体,有效载荷,链接器) 之间的相关性.
- 阐明ADC治疗中严重不良事件的驱动因素.
主要方法:
- 对所有已批准的抗体与药物合物的毒性数据进行了全面分析.
- 评估特定ADC组件与观察到的安全概况之间的相关性.
- 对不同类型的ADC进行器官特异性毒性评估和比较.
主要成果:
- 有效载荷类型和作用机制与剂量修改或3级+毒性没有显著的相关性.
- 大多数观察到的毒性与有效载荷对非转化组织的作用有关,而不是与瘤相关的抗原.
- 具体例子包括与有效载荷相关的腹和与抗原相关的皮肤毒性,基于抗原表达水平没有显著的毒性差异.
结论:
- 与ADC相关的毒性主要受到有效载荷对正常组织的影响.
- 虽然有效载荷是主要的驱动因素,但对所有ADC组件的彻底评估至关重要.
- 建议对特定组件进行分析,以预测和管理ADC安全配置文件.

Phase II Conjugation Reactions: Overview
Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Antidotes
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...
