研究发现,伊布替尼联合利妥昔单抗可显著改善瓦尔登斯特伦巨球蛋白血症患者症状,大幅提高无进展生存率

伊布替尼对瓦尔登斯特伦巨球蛋白血症具有明确的治疗效果,近日研究人员考察了伊布替尼联合利妥昔单抗对瓦尔登斯特伦巨球蛋白血症患者的疗效。

150名患者参与研究,随机接受伊布替尼+利妥昔单抗联合治疗或利妥昔单抗治疗。主要终点是无进展生存,次要终点包括响应率、持续血液学改善以及安全性。通过骨髓标本检测MyD 88和CXCR 4的突变状态。

治疗30个月后,联合治疗组患者无进展生存率为82%,利妥昔单抗组仅为28%(进展或死亡HR=0.20),治疗效果不依赖MyD 88和CXCR 4亚型。联合治疗组治疗响应率 (72% vs 32%)以及血红蛋白持续增加率(73% vs 41%)更高。治疗导致的最常见不良事件包括输液相关反应、腹泻、关节痛和恶心。联合治疗组患者房颤高血压风险增加,但输注反应和IgM耀斑事件风险降低,组间主要血液学事件发生率相近。

研究发现,伊布替尼联合利妥昔单抗可显著改善瓦尔登斯特伦巨球蛋白血症患者症状,大幅提高无进展生存率。
