概括
经过修改的伊皮利穆马布 (IPI) 与尼沃卢马布 (NIVO) 结合的剂量表显著降低了晚期细胞癌 (aRCC) 患者的严重副作用. 这种新的IPI表格显示了更好的毒性概况的前景,而不会影响疗效.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 临床试验 临床试验
背景情况:
- 伊皮利马布 (IPI) 加尼沃马布 (NIVO) 是对晚期细胞癌 (aRCC) 的标准一线治疗方法.
- 优化这种组合的毒性概况对于患者管理至关重要.
研究的目的:
- 评估IPI (每12周一次) 的修改剂量计划与NIVO相结合,与标准IPI计划 (每3周一次) 相比,是否提供更好的毒性概况.
- 评估修改后的IPI加NIVO在未经治疗的清晰细胞ARCC患者中的安全性和有效性.
主要方法:
- 一个随机的II期试验招募了以前没有接受过治疗的清晰细胞aRCC患者.
- 患者被分为2:1接受四剂修改或标准IPI (1 mg/kg) 和NIVO (3 mg/kg) 的患者.
- 主要终点是3-5级治疗相关不良事件 (trAEs) 的发生率;一个关键的次要终点是12个月无进展生存期 (PFS).
主要成果:
- 修改IPI (32.8%) 与标准IPI (53.1%) 相比,3-5级trAEs的发生率明显较低.
- 经过修改的手臂的12个月PFS为46.1%.
- 随访时间中位数为21个月;整体应答率为45.3% (修改) 与35.9% (标准),PFS中位数分别为10.8个月和9.8个月.
结论:
- 修改后的IPI剂量计划显著减少了aRCC患者治疗相关的严重不良事件.
- 虽然12个月的PFS没有达到与历史对照对比的预规定的值,但修改版和标准IPI手臂之间的疗效似乎可以比较.

Tumor Immunotherapy
533
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.

Combination Therapies and Personalized Medicine
4.9K
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...
