CLIN CANCER RES:NHS-IL12治疗转移性实体瘤

2019-01-20 MedSci MedSci原创

NHS-IL12免疫细胞因子由NHS76抗体融合的两个IL12异二聚体组成。临床前研究表明,该抗体通过与游离DNA片段的组蛋白结合,将IL12靶向运输到肿瘤坏死区域,从而增强抗肿瘤活性。CLIN CANCER RES近期发表了一篇文章,研究NHS-IL12治疗晚期实体患者的最大耐受剂量(MTD)和药代动力学。

NHS-IL12免疫细胞因子由NHS76抗体融合的两个IL12异二聚体组成。临床前研究表明,该抗体通过与游离DNA片段的组蛋白结合,将IL12靶向运输到肿瘤坏死区域,从而增强抗肿瘤活性。CLIN CANCER RES近期发表了一篇文章,研究NHS-IL12治疗晚期实体患者的最大耐受剂量(MTD)和药代动力学。

患者(n = 59)在单个递增剂量组中接受NHS-IL12皮下治疗,随后是多个递增剂量组(每4周给药n = 37)。研究结果表明,最常见的治疗相关不良事件(TRAE)包括循环淋巴细胞减少,肝转氨酶增加和流感样症状。≥3级TRAE都是暂时的,只有一个是症状性的(多汗症)。MTD为16.8μg/ kg。NHS-IL12治疗后观察到IFNγ的升高和IL10升高。在外周免疫细胞亚群中,最显着的是活化和成熟的自然杀伤(NK)细胞和NKT细胞的频率增加。T细胞受体测序分析表明,治疗后观察到T细胞受体多样性和肿瘤浸润淋巴细胞密度的增加。虽然没有观察到客观的肿瘤反应,但5名患者病情持续稳定。

文章最后认为,NHS-IL12耐受性良好,最高剂量为16.8μg/ kg,也是推荐的II期剂量。早期临床免疫相关活动值得进一步研究,包括与免疫检查点抑制剂联合使用。
