概括
洛拉提尼布在亚洲患者中表现出较高的无进展生存期 (PFS) 与克里佐替尼布相比,亚洲患者患有晚期形淋巴瘤激酶阳性非小细胞肺癌. 长达五年的随访证实了洛拉提尼布在这个小组中的持续有效性和安全性.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 洛拉提尼布是一种第三代形淋巴瘤激酶 (ALK) 抑制剂.
- 皇冠试验 (NCT03052608) 显示,洛拉替尼比克里佐替尼在先前未经治疗的ALK阳性高级非小细胞肺癌 (NSCLC) 中,改善了无进展生存期 (PFS).
- 以前的研究结果表明,亚洲亚组的疗效类似.
研究的目的:
- 在亚洲患者之前未接受过治疗的ALK阳性晚期NSCLC中,对lorlatinib与crizotinib进行更新的子组分析.
- 在大约五年的随访后评估长期疗效和安全结果.
主要方法:
- 对CROWN第三阶段试验进行的后期分析.
- 患者被随机分配 (1:1) 接受洛拉提尼布 (100毫克每天一次) 或克里佐提尼布 (250毫克每天两次).
- 分析了研究人员评估的疗效,安全性和生物标志物数据.
主要成果:
- 洛拉提尼布的PFS中位数未达到,而克里佐替尼布的PFS中位数为9.2个月 (HR=0.22).
- 洛拉提尼布的5年PFS率为63%的洛拉提尼布和7%的克里佐提尼布.
- 内客观反应率为洛拉提尼布的69%,而克里佐替尼布的6%,而洛拉提尼布的内进展时间中位数未达到.
结论:
- 洛拉提尼布在亚洲患有晚期ALK阳性NSCLC的患者中表现出持续的疗效和一致的安全性.
- 在这组小组中,经过五年的随访后,Lorlatinib仍然无法达到PFS.
- 结果与CROWN试验中总体人口发现一致.

Targeted Cancer Therapies
7.4K
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.

lncRNA - Long Non-coding RNAs
8.5K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
