这些试验表明 FLAG 方案化疗联合异基因 KIR 配体错配的 CD56+NK/NKT 样细胞输注是安全的,并可能作为 36.3% 的难治/复发性非 M3 AML 患者通往 HSCT 的有效桥接。
急性髓系白血病(AML)是一种侵袭性疾病,总生存率欠佳,尤其是在复发/难治性患者中。这类患者挽救治疗的主要目标是实现最佳疾病控制,从而能够过渡到造血干细胞移植(HSCT),而HSCT仍是其中一部分患者唯一的治愈选择。异基因KIR配体错配的CD56+NK/NKT样细胞已显示出抗白血病活性,并为开发新型细胞疗法提供了一个有前景的平台。
复发/难治性非M3 AML患者,不适合HSCT者被纳入这项I期临床试验。患者接受FLAG预处理方案,随后以5天间隔接受三个递增剂量(1 × 10⁶、3 × 10⁶、5 × 10⁶ cells/kg)的CD56 + NK/NKT样细胞。
共11例患者入组研究,中位年龄41.5岁。他们平均接受过三线既往化疗,骨髓中原始细胞比例为18%。CD56⁺ NK/NKT样细胞输注是安全的,未在任何患者中观察到严重毒性或移植物抗宿主病(GVHD)。遵循该治疗方案后,五例患者(45.4%)达到完全缓解(CR),伴或不伴血细胞计数恢复。其中四例患者(36.3%)成功接受HSCT,并至随访期结束时保持无事件。
A total of 11 patients with a median age of 41.5 years were enrolled in the study. On average, they received three lines of prior chemotherapy and showed 18% blasts in their bone marrow. The infusion of CD56⁺ NK/NKT-like cells was safe, with no serious toxicity or graft-versus-host disease (GVHD) observed in any patient. Following this treatment protocol, five patients (45.4%) achieved complete remission (CR), with or without hematologic count recovery. Four of these patients (36.3%) underwent successful HSCT and remained event-free to the end of the follow-up period.
Overall, these trials indicated that the FLAG regimen chemotherapy combined with allogeneic KIR ligand-mismatched CD56 + NK/NKT-like cell infusion is safe and may serve as an effective bridge to HSCT in 36.3% of patients with refractory/relapsed non-M3 AML.
