概括
雷米克斯研究表明,在现实环境下,伊克萨佐米布联合治疗 (IXA-Rd) 为复发性/耐药性多发性骨髓瘤患者提供了19.1个月的中位数无进展生存期. 这种口服蛋白酶体抑制剂组合显示出有效性和可接受的耐受性,即使在老年人群中也是如此.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床研究 临床研究
背景情况:
- 伊克萨佐米布 (IXA) 是一种口服的蛋白酶体抑制剂 (PI),用于与列纳利多米德和德克萨美 (IXA-Rd) 治疗复发性和/或耐火性多发性髓瘤 (RRMM).
- 现实世界的数据对于了解不同患者群体的治疗有效性至关重要.
研究的目的:
- 评估ixazomib,lenalidomide和dexamethasone (IXA-Rd) 在RRMM患者的大型,现实世界队列中的有效性和安全性.
- 在接受IXA-Rd的患者中评估无进展生存率 (PFS) 和整体响应率 (ORR),在第二线或后期治疗环境中.
主要方法:
- 雷米克斯研究是一项在法国进行的非干预性,前性,现实世界的分析 (2017年8月至2019年10月).
- 376名RRMM患者接受二线或之后的IXA-Rd治疗,被跟踪至少24个月.
- 主要终点是中位数无进展生存期 (mPFS);次要终点包括整体反应率 (ORR) 和安全.
主要成果:
- 无进展生存 (mPFS) 的中位数为19.1个月 (95% CI [15.9, 21.5]),整体应答率 (ORR) 为73.1%.
- 根据治疗线路的mPFS变化:21.5个月 (L2),21.9个月 (L3) 和5.8个月 (L4+).
- 80岁以下的患者和80岁以上的患者的疗效和耐受性相似; 78.2%的患者经历了不良事件,21%的患者因毒性而停止了IXA.
结论:
- 雷米克斯研究的结果与土耳马林-MM1试验一致,证实了IXA-Rd组合在RRMM中的实际益处.
- IXA-Rd在老年和可能更脆弱的RRMM群体中表现出可接受的有效性和耐受性.
- 这项分析支持IXA-Rd在常规临床实践中用于RRMM管理的使用.

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
202
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
