概括
用达拉图穆马布早期干预燃烧的多发性骨髓瘤 (SMM) 显示出有希望的长期结果. 据CENTAURUS研究表明,达拉图穆马布是一种可容忍的选择,可以延迟SMM进展到活跃的多发性髓瘤.
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:
- 燃烧多发性骨髓瘤 (SMM) 是活跃多发性骨髓瘤 (MM) 的前体.
- 早期干预策略的目的是延迟或防止进展到症状MM.
- 达拉图马布是有效的MM治疗的既定疗法,但其在SMM早期干预中的作用正在研究中.
研究的目的:
- 介绍CENTAURUS第二阶段研究的最终分析,评估中等/高风险SMM中达拉图穆马布的不同剂量表.
- 评估早期达拉图穆马布干预SMM的长期疗效和安全性.
主要方法:
- 123名中等/高风险SMM患者被随机分为三个臂:长时间强烈,中等或短时间强烈的IV达拉图马布剂量表.
- 该研究涉及85.2个月的中位随访期,一些患者在延长阶段继续治疗.
- 关键的终点包括应答率,进展率,无进展生存率 (PFS) 和整体生存率 (OS).
主要成果:
- 完整反应或更好的比率为4.9% (长时间强烈),9.8% (中级) 和0% (短时间强烈).
- 总体响应率分别为58.5%,53.7%和37.5%.
- 在长时间强烈治疗的手臂中,没有达到无进展的中位生存期,为84.4个月 (中等) 和74.1个月 (短时间强烈). 在任何一个手臂中都没有达到中位数的整体存活率.
结论:
- 来自CENTAURUS研究的扩展后续数据表明,达拉图穆马布在SMM患者中的耐受性.
- 这些发现支持对达拉图马布作为一种早期干预策略的调查,以延迟中期/高风险SMM的进展.
- 这项研究强调了达拉图穆马布在这种患者群体中实现持久反应和长期无进展生存的潜力.

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...
