嵌合抗原受体(CAR) T细胞已被证明对复发性/难治性(R/R) 急性B细胞淋巴细胞白血病患者具有临床益处。Curran等人开展了一项多中心的临床试验,检测这种疗法的毒性、可行性和反应性。共招募了25位R/R B-ALL患儿或青年患者(1-22.5岁),予以19-28z CAT T细胞治疗。条件化疗包括高剂量(3 g/m2)环磷酰胺(HD-Cy) 17例,低剂量(≤1.5 g/m2)环磷酰胺(LD

嵌合抗原受体(CAR) T细胞已被证明对复发性/难治性(R/R) 急性B细胞淋巴细胞白血病患者具有临床益处。Curran等人开展了一项多中心的临床试验,检测这种疗法的毒性、可行性和反应性。

共招募了25位R/R B-ALL患儿或青年患者(1-22.5岁),予以19-28z CAT T细胞治疗。条件化疗包括高剂量(3 g/m2)环磷酰胺(HD-Cy) 17例,低剂量(≤1.5 g/m2)环磷酰胺(LD-Cy) 8例。

15位患者有预处理微小残留病灶(MRD;骨髓原代细胞<5%),10位患者有预处理形态学证据(骨髓原代细胞≥5%)。

所有毒性作用可逆,包括重度细胞因子释放综合征(16%,4/25)和重度神经毒性(28%,7/25)。所有治疗的患者被纳入反应性分析,在24位可评估的患者中,与没有增加毒性的LD-Cy/形态学组相比,HD-Cy/MRD 队列患者的反应性和CAR T细胞扩增峰值均更佳。

本研究表明CD19特异性CAR T细胞疗法用于R/R B-ALL患者安全性良好。条件化疗的强度和微小预处理病灶负担对反应性有正性效应,且对毒性无副作用。

安进宣布两项三期双特异性抗体BLINCYTO(靶向CD3和CD19)治疗小儿复发性急性淋巴细胞白血病患者的阳性结果

Amgen宣布其双特异抗体BLINCYTO(blinatumomab)(同时靶向CD3和CD19)针对小儿复发B细胞急性淋巴细胞白血病(ALL)的全球多中心3期临床试验(20120215)的中期分析结果已达到了无事件生存的主要终点。

Sci tranal med:BAFF-R靶向CAR T细胞疗法可克服B细胞恶性肿瘤的CD19抗原缺失

嵌合抗原受体(CAR)T细胞疗法治疗B细胞恶性肿瘤是CD19靶向CAR T细胞治疗的先驱。CD19靶向CAR T细胞为B细胞恶性肿瘤提供了新的治疗选择。但CD19抗原缺失所造成的肿瘤复发极大限制了治疗效果。研究人员构建了一种人源的二代CAR T细胞,靶向另一种B细胞特异性的标志物——B细胞激活因子受体(BAFF-R),已证实对人类淋巴瘤和急性淋巴细胞白血病(ALL)系细胞具有细胞毒性。BAFF-R

Blood:既可缓解CD19 CAR T细胞细胞因子释放综合征,又不减弱抗白血病疗效

采用CD19特异性嵌合抗原受体重定向的T细胞适配性转移的免疫疗法治疗B系急性淋巴细胞白血病,可挽救80%以上的复发性/难治性疾病患者。这种新形式的治疗指数由于CAR T细胞移植时出现的免疫毒性综合征而降低。

Blood:CD19 CAR-T细胞免疫疗法有助于难治性/复发性滤泡性淋巴瘤患者获得持久的缓解

在初次化学免疫治疗后早期复发的、难治性的或存在组织学转化(tFL)的滤泡性淋巴瘤(FL)患者的无进展存活期和总体生存期有限。近日,Alexandre V. Hirayama等人在《Blood》杂志上发表了其对21位复发性/难治性(R/R)FL(8位)和tFL(13位)患者的长期随访结果。这21位患者均参与了采用环磷酰胺和氟达拉滨淋巴细胞清除+输注2x106/kg CD19导向的嵌合抗原受体修饰的T

大剂量化疗后进行自体干细胞移植(HDT-ASCT)是复发性或化疗难治性弥漫性大B细胞淋巴瘤(rel/ref DLBCL)的标准疗法。但只有50%的患者用这种方法治愈。HDT-ASCT后予以CD19特异性嵌合抗原受体(CAR) T细胞是否可以提高患者的无进展存活期 (PFS)? Craig S. Sauter等人对此进行研究。
