ASH 18 比较完整的更新-2018-12-01

大家凑合看吧,周末懒得仔细搞了

1 细胞治疗的鸟瞰,毕竟是血液肿瘤

2 BCMA CAR-T治疗多发性骨髓瘤的比较

3  4SCAR2.0

results from phase I/II trial of the multi-target 4SCAR2.0 therapy for thetreatment of highly resistant relapsed/refractory lymphomas have demonstrated increased safety and improved response rate

来自寨都的研究,比较多靶点CAR-T【注:单靶点联用】和单靶点CAR-T的安全性缓解率

这里的4SCAR2.0,4是指4th gen,S代表safe,这里在机制上引入了induced caspase9,可以用小分子诱导CAR-T的凋亡(但具体哪个小分子没深入研究)

iCas9:inducible caspase 9

可以看出不管是ORR还是CR ,双CAR-T都比单CAR-T明显提升

体内扩增的动力学(感觉这种比bi-specific方便检测各个靶点CAR-T)

First human data with MSKCCauto/trans co-stimulated CD19 CAR

po图之前放该研究之前的临床前研究数据

加了截短的EGFR这个已经耳熟能详,这里除了CD28之外,在膜上表达了4-1BBL:CD28 CAR功能更强,4-1BB更持久——这样除了激活同个T细胞上的4-1BB/4-1BBL通路(auto),还能激活其它T细胞上的4-1BB/4-1BBL通路(trans),临床前的结果显示抗肿瘤效果更加平衡,通过提高CD8+ T/CD4+ T 的比例和降低耗竭来提升T细胞持久性,另外这种改造也诱导T细胞中IRF7/INFβ通路来优化CAR-T介导的肿瘤清除

CRS和神经毒性:

整体上CRS 62%,但是没有观察到严重CRS

整体上NTX 34%,3-4级的6%,但没有观察到4-5级NTX和脑水肿

临床缓解率:整体ORR 83%  CR 54%

个人感觉亮点还是safety

5 axi-cel的真实世界与ZUMA-1的比较

缓解率接近,但是RW中DoR更短

Comparison of axi-cel in“real world” (RW) versus ZUMA-1: overall similar response rates but duration of response might be shorter in the RW. Further follow-up warranted (~ 6 months inRW COHORT)

Updates of KYMRIAH®(tisagenlecleucel) in Eliana (pediatric ALL)

 Updates of KYMRIAH®(tisagenlecleucel) in Juliet (DLBCL)

AMG 330 (CD33 BITE) 

first-in-human AML study n=40, but 35 patients discontinue

Only 12.5% ORR

9 RG6026(2 CD20+1 CD3)

all Pts get obinutuzumab pre-treatment, dose dependent responses, no CR has relapsed in limited follow up

10 MGN632 (CD123 ADC) in CD123+ve AML/BPDCN

One possibly related death

IMGN632 (CD123 ADC) efficacy in CD123+veAML/BPDCN
