概括
较高剂量的伊皮利马布 (10 mg/kg) 加上泰莫索洛米德在先进的黑色素瘤患者中改善了无进展的存活率,这些患者对先前的免疫疗法有抗性. 这种组合疗法对耐火性黑色素瘤病例具有潜在的益处.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 黑色素瘤研究 黑色素瘤研究
背景情况:
- 在ipilumab + nivolumab治疗中进展的晚期黑色素瘤患者的预后不好.
- 伊皮利马布 (Ipi) 呈现剂量反应活性,这表明更高的剂量可能会改善结果.
- 结合10毫克/公斤 (Ipi10) 和temozolomide (TMZ) 的ipilimumab是一种对耐火病例的有希望的策略.
研究的目的:
- 评估伊皮利穆马布10毫克/千克+泰莫索洛米德在晚期黑色素瘤患者的疗效,这些患者不耐伊皮利穆马布+尼沃卢穆马布治疗.
- 为了在类似的患者群体中比较Ipilimumab 3 mg/kg + temozolomide的结果.
- 探索与治疗反应相关的分子变化.
主要方法:
- 对接受伊皮利穆马布10毫克/公斤+泰莫索洛米德 (n=6) 治疗的晚期黑色素瘤患者的回顾性队列分析,与伊皮利穆马布3毫克/公斤+泰莫索洛米德 (n=6) 相比.
- 在10毫克/千克的伊皮利穆马布队列中的患者在之前的伊皮利穆马布 + 尼沃卢马布治疗中进展.
- 瘤分子剖析 (WES,RNA-seq) 在一个受试者的样本上进行.
主要成果:
- 与Ipilimumab 3 mg/kg + temozolomide (44天) 相比,Ipilimumab 10 mg/kg + temozolomide (144.5天) 的中位数无进展生存时间明显长 (p=0.04).与Ipilimumab 3 mg/kg + temozolomide (44天) 相比,Ipilimumab 10 mg/kg + temozolomide的中位数无进展生存时间明显长 (p=0.04).
- 在服用较高剂量的伊皮利马布组中,观察到总体存活时间更长的趋势.
- 在10毫克/公斤伊皮利穆马布队列中观察到两个部分反应,两者都发生在患有BRAF V600E突变黑色素瘤的患者中.
- RNA-seq揭示了治疗后炎症和干扰素特征的增加和免疫抑制剂的下调.
结论:
- 伊皮利穆马布10毫克/千克+泰莫索洛米德在不耐伊皮利穆马布+尼沃卢穆马布治疗的晚期黑色素瘤患者中显示出有效性.
- 为了克服免疫疗法耐药性,可能需要更高的伊皮利马布剂量.
- 分子数据表明,较高的伊皮利穆马布剂量可以增强抗瘤免疫反应.

Tumor Immunotherapy
457
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Skin Cancer
3.0K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
