概括
三级暴露多发性骨髓瘤患者需要进一步治疗,但目前的治疗方法有效性有限,医疗负担高. 需要新的疗法来改善复发性/耐药性多发性髓瘤的治疗结果.
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:
- 多发性骨髓瘤 (MM) 的治疗依赖于免疫调节药物 (IMiD),蛋白酶体抑制剂和单克隆抗体 (MAbs).
- 尽管有进展,MM仍然无法治愈,需要进一步的治疗线 (LOT) 患者,特别是在三级暴露 (TCE) 后.
研究的目的:
- 调查TCE患者的现实世界治疗模式,临床结果和医疗保健利用情况,以开始随后的LOTs.
- 识别治疗复发性或耐火性多发性骨髓瘤的未满足需求.
主要方法:
- 在阿尔伯塔省卫生系统数据库中,从2012年1月到2022年12月接受后续LOT的TCE患者的回顾性分析.
- 收集的数据包括人口统计,使用的药物类别,到下一次治疗或死亡的时间 (TTNT-D) 和医疗保健遭遇.
主要成果:
- 分析了221名TCE患者,平均年龄为70岁.
- 单克隆抗体 (MAbs) 和IMiD分别是第一个和第二个LOT的常见病例.
- 中位数TTNT-D为10.1个月,中位数TTNT为18.1个月,总生存时间为18.7个月.
- 随后的LOT产生了大量的医疗保健利用,包括急诊,住院和众多诊所/输液预约.
结论:
- 目前对TCE患者的后续治疗有效性有限,并对医疗保健系统造成重大负担.
- 对于具有新作用机制的新疗法,有明显的未满足的需求,以改善复发性/耐药性多发性骨髓瘤患者的治疗结果.

Treatment Resistant Cancers
3.7K
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...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
387
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Therapeutic Drug Monitoring: Overview and Classification
279
Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood at designated intervals to ensure the drug concentration stays within a therapeutic range. This monitoring is crucial for optimizing individual dosage regimens, enhancing therapeutic efficacy, and minimizing drug-related toxicity. TDM is vital for drugs with narrow therapeutic windows, significant variability in pharmacokinetics, and a clear correlation between plasma levels and...
