概括
复发或不耐抗CD38单克隆抗体 (MoAB) 治疗多发性骨髓瘤的患者面临糟糕的结果. 对于这个患者群体,迫切需要新的治疗方法.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
背景情况:
- 抗CD38单克隆抗体 (MoAB) 治疗,如达拉图巴,已经改变了多发性骨髓瘤治疗.
- 然而,很大一部分患者会复发或对这些疗法产生耐药性.
- 了解抗CD38 MoAB后进展的患者的结果对于开发后续治疗策略至关重要.
研究的目的:
- 描述抗CD38 MoAB治疗后复发或成为耐火性 (R/R) 的多发性骨髓瘤患者的自然史和结果.
- 为了确定影响该R/R群体生存的预后因素.
主要方法:
- 对81名多发性骨髓瘤患者的回顾性分析,这些患者在一个中心接受了达拉图马布治疗.
- 收集的数据包括先前的治疗,耐火性状态 (三级,五级耐火),随后的治疗和整体存活率 (OS).
主要成果:
- 该队列在很大程度上接受了预治疗,大多数患者先前接受了免疫调节药物 (IMID) 和蛋白酶体抑制剂 (PI).
- 全球平均整体存活期 (OS) 为21个月,三级耐火患者显著下降至14个月,五级耐火患者为5个月.
- 大多数患者接受了daratumumab进展后的进一步治疗,包括新药,如抗BCMA疗法和CAR T细胞疗法在少数情况下.
结论:
- 患者R/R对达拉图马布代表了一个未满足的临床需求,预后不佳.
- 后续疗法的有效性有限凸显了对这种耐火性多发性骨髓瘤患者群体的新型治疗方法的迫切需求.

Treatment Resistant Cancers
3.3K
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...

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.
