概括
与未经治疗的慢性淋巴细胞白血病 (CLL) 患者的化学免疫治疗相比,固定时间的acalabrutinib-venetoclax,有或没有obinutuzumab,显著改善了无进展的存活率. 这种组合疗法为新诊断的CLL提供了新的护理标准.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床试验 临床试验
背景情况:
- 慢性淋巴细胞白血病 (CLL) 是一种常见的淋巴细胞恶性瘤.
- 对CLL的最佳一线治疗策略仍然是积极研究的领域.
- 与标准化疗免疫疗法对抗新型向疗法的评估对于改善患者的治疗结果至关重要.
研究的目的:
- 为了比较固定的持续时间的acalabrutinib-venetoclax,与或没有obinutuzumab,与以前未经治疗的CLL患者的化疗免疫治疗的疗效.
- 评估无进展生存期 (PFS) 作为主要终点.
- 评估治疗方案的整体存活率 (OS) 和安全性概况.
主要方法:
- 第三期,开放标签,随机试验,涉及867名未经治疗的CLL患者,没有17p删除或TP53突变.
- 患者被分配1:1:1的acalabrutinib-venetoclax,acalabrutinib-venetoclax-obinutuzumab,或研究人员选择的化疗免疫疗法 (fludarabine-cyclophosphamide-rituximab或bendamustine-rituximab).
- 主要终点是通过盲目的独立中央审查评估的PFS.
主要成果:
- 在40.8个月的随访中位数,36个月的PFS为acalabrutinib-venetoclax的76.5%,acalabrutinib-venetoclax-obinutuzumab的83.1%和化学免疫治疗的66.5%.
- 阿卡拉布鲁丁尼-维内托克拉克斯显著改善了PFS与化疗免疫疗法相比 (HR,0.65;P=0.004).
- 最常见的不良事件是3级+的中性质减退;与COVID-19相关的死亡分别发生在10,25和21名患者中.
结论:
- 固定持续时间的acalabrutinib-venetoclax,有或没有obinutuzumab,在以前未经治疗的CLL中,与化疗免疫疗法相比,显示出优异的PFS.
- 这些发现支持使用向治疗组合作为一线CLL治疗的新标准.
- 进一步的研究可能会探索长期结果和特定的患者子组.

Combination Therapies and Personalized Medicine
4.8K
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...

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.
