概括
美国食品和药物管理局批准了niraparib加上abiraterone酸盐和普得尼松用于BRCA突变的转移性割抵抗性前列腺癌. 这种组合显著改善了BRCAm mCRPC患者的无进展生存率.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学 是一个学科.
- 临床试验 临床试验
背景情况:
- 转移性割抵抗性前列腺癌 (mCRPC) 是前列腺癌的晚期阶段.
- BRCA突变 (BRCAm) 是在mCRPC患者中发现的同源重组修复突变 (HRRm) 的一个子集.
- 对于mCRPC的标准治疗通常涉及雄激素剥夺疗法,但耐药性发展.
研究的目的:
- 评估尼拉巴里布和阿比拉乙酸 (AA) 与普德尼松 (P) 的固定剂量组合 (FDC) 的疗效和安全性.
- 为了支持FDA对BRCA突变 (BRCAm) 转移性割抵抗性前列腺癌 (mCRPC) 的成年患者的批准.
主要方法:
- 一项双盲随机试验 (MAGNITUDE研究,NCT03748641) 分派了423名mCRPC和HRRm患者.
- 患者接受了尼拉帕里布加AA和P,或安慰剂加AA和P.
- BRCAm状态是分层因素,放射性无进展生存率 (rPFS) 是主要终点.
主要成果:
- 在BRCAm亚群中,niraparib + AA + P手臂的中位数rPFS为16.6个月,而安慰剂手臂的中位数为10.9个月 (HR0.53;p=0.0014).
- 虽然在所有HRRm人群中,rPFS有所改善,但FDA的分析表明,好处主要是由BRCAm子组推动的.
- 观察到毒性增加,包括27%的组合手臂患者需要输血的贫血.
结论:
- 美国食品和药物管理局批准了niraparib + AA + P FDC用于BRCAm mCRPC的成年患者.
- 批准是基于在MAGNITUDE试验的BRCAm亚群中证明的RPFS显著改善.
- 这项研究强调了遗传生物标志物在指导前列腺癌治疗决策中的重要性.

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...

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.
