Ipilimumab is a fully human monoclonal antibody IgG1κ that blocks the inhibitory receptor cytotoxic T lymphocyte antigen 4 (CTLA-4) on T cells. Ipilimumab can be used in unresectable or metastatic melanoma (MM) studies.

Ipilimumab 抑制 CTLA-4，使 T 细胞免疫反应对肿瘤细胞重新激活。Ipilimumab 可作为单剂或与细胞因子、化疗或疫苗联合使用，促进抗肿瘤活性。
Ipilimumab (0，5 or 50 μg/ mL, 6 days) 单独使用可增强 IL-2 的产生，与 nivolumab 联合使用可刺激外周血单核细胞（PBMC）中更高的 IL-2 释放。而 ipilimumab 和 nivolumab 联合处理可协同增强效应性和记忆性 T 细胞反应。

Ipilimumab（静脉注射，3 或10mg/kg，每周一次，持续 4 周）联合 nivolumab（10 或 50mg/kg）导致食蟹猴的胃肠道炎症，并与白蛋白减少、球蛋白增加、中性粒细胞和嗜酸性粒细胞计数增加以及大肠单核炎症有关。高剂量组表现为反复腹泻，其胰腺中的腺泡细胞也有明显的脱颗粒现象。
