中文摘要

CAR-T 细胞疗法已成为治疗复发/难治性血液系统恶性肿瘤的突破性疗法。然而,CAR-T 细胞扩增和持续存在不足是治疗失败的主要原因。外源性或转基因细胞因子有望增强CAR-T 细胞效力,但可能加重毒性。我们提出一种化学-遗传系统,利用已过专利期的抗癌分子胶降解剂来那度胺及其类似物作为开关,实现细胞因子功能的时空控制。与CAR共同递送时,膜结合且可被来那度胺降解的IL-7融合蛋白可赋予有利于临床的T细胞表型,增强抗原依赖性增殖能力,并提高体内肿瘤控制效果。此外,通过周期性药物控制CAR和细胞因子丰度,可在兼顾抗肿瘤效力和T细胞过度增殖的双重模型中应用活性强、经IL-7增强的CAR-T 细胞。

CAR-T cell therapy has emerged as a breakthrough therapy for the treatment of relapsed and refractory hematologic malignancies.

However, insufficient CAR-T cell expansion and persistence is a leading cause of treatment failure. Exogenous or transgenic cytokines have great potential to enhance CAR-T cell potency but pose the risk of exacerbating toxicities.

Here we present a chemical-genetic system for spatiotemporal control of cytokine function gated by the off-patent anti-cancer molecular glue degrader drug lenalidomide and its analogs. When co-delivered with a CAR, a membrane-bound, lenalidomide-degradable IL-7 fusion protein enforced a clinically favorable T cell phenotype, enhanced antigen-dependent proliferative capacity, and enhanced in vivo tumor control.

Furthermore, cyclical pharmacologic combined control of CAR and cytokine abundance enabled the deployment of highly active, IL-7-augmented CAR-T cells in a dual model of antitumor potency and T cell hyperproliferation.
