概括
将venetoclax添加到吉尔特里尼布并没有改善复发FLT3突变AML患者的结果. 虽然生存率显示出有利于组合的趋势,但它增加了毒性,但没有改善缓解或移植率.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 患有FLT3突变急性髓性白血病 (AML) 的患者在强化诱导治疗后出现复发或耐药性疾病,预后不佳.
- 吉尔特里尼布是复发性/耐药性 (R/R) FLT3突变AML的标准治疗方法.
- 研究新型组合疗法对于改善这一具有挑战性的患者群体的治疗结果至关重要.
研究的目的:
- 为了评估结合venetoclax与吉尔特利尼布的疗效和安全性,与R/R FLT3突变AML中的吉尔特利尼布单一治疗相比.
- 评估该组合对缓解率,全源造血干细胞移植 (HSCT) 实现和整体存活率 (OS) 的影响.
主要方法:
- 一项回顾性研究包括36名在密集化疗后患有R/RAML的患者.
- 患者接受了吉尔特利尼布单一治疗 (n=19) 或吉尔特利尼布加维尼托克拉克斯 (gilt-ven) 联合治疗 (n=17).
- 结果包括复合完全缓解率 (mCRc),HSCT率,OS和毒性在两组之间进行了比较.
主要成果:
- 在吉尔特利尼布和黄金组之间,没有观察到mCRc率 (53%对65%,p=0.51) 或HSCT实现率 (47%对35%,p=0.5) 的显著差异.
- 整体存活率是可比的,尽管Gilt-ven (58.8%) 与吉尔特利尼布 (42.1%) 发现了改善12个月生存率的趋势.
- 早期救援用黄金证明了生存益处 (p=0.031),但这种组合与血液毒性增加有关.
结论:
- 与吉尔特利尼布单独治疗相比,吉尔特利尼布和威尼托克拉克斯的联合治疗没有改善R/RFLT3突变AML的缓解或HSCT率.
- 虽然OS显示了有利于组合的趋势,但它与血液毒性增加有关.
- 早期的顺序性救援疗法用吉尔特利尼布和venetoclax可能提供生存优势,保证进一步的研究.

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...

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.
