下一代肿瘤不可知靶点即将出现
Next-generation tumor-agnostic targets on the horizon.
肿瘤不可知药物开发将肿瘤学重新聚焦于共享的分子依赖性而非组织来源,从而能够针对跨肿瘤的罕见可操作驱动因素进行高效开发。

主要终点:Safety of TILs/CAR-TILs treatment in advanced solid cancers · Assessing Number of participants with treatment-related adverse events as assessed by CTCAE v4.0. · up to 36 months
次要终点:Primary clinical efficacy of the TILs/CAR-TILs treatment in advanced solid cancers
从晚期实体瘤患者获取TIL/CAR-TIL并回输,以评估治疗的安全性和临床疗效。
研究者从晚期癌症患者体内获取肿瘤浸润淋巴细胞(TIL),对其进行工程化改造以敲除PD-1基因、表达分别靶向PD-1和CTLA-4的单链可变片段(scFv),并表达针对不同抗原的嵌合抗原受体(CAR),随后将细胞回输患者。研究将评估这些TIL的安全性、耐受性及初步临床疗效。
Tumor infiltration lymphocytes (TILs) have been harvested from advanced cancer patients and constructed to knockout PD1 gene and express scFvs against both PD1 and CTALA4 and CARs against various antigens, followed by transfusion into the patients. The safety, tolerance, and preliminary clinical efficacy of the TILs will be evaluated.
