介绍

:虽然许多方法已用于治疗肝细胞癌 (HCC),但临床益处有限,尤其是对于晚期 HCC。然而,最近使用 PD-1/PD-L1 抑制剂单药治疗及其与其他疗法的联合治疗已显示出显着的效果。 Camrelizumab 是一种选择性、人源化、高亲和力的 IgG4 PD-1 单克隆抗体,已被中国国家药品监督管理局批准用于晚期 HCC 患者的二线治疗。
覆盖区域

:本文介绍了晚期 HCC 的抗 PD-1/PD-L1 免疫疗法,并就卡瑞珠单抗治疗晚期 HCC 的药理学、安全性和有效性进行了讨论。它还考虑了在这种情况下卡瑞珠单抗的未来研究方向。
专家意见

:camrelizumab 的 PD-1 结合表位与其他 PD-1 抑制剂不同。 camrelizumab抑制PD-1与PD-L1结合的IC50和EC50与pembrolizumab相似,明显低于其他PD-1抑制剂,对PD-1位点有更高的亲和力。 Camrelizumab 在晚期 HCC 中表现出与其他 PD-1 抑制剂相似的有希望的抗肿瘤活性和可接受的安全性。阿帕替尼(一种 VEGFR-2 酪氨酸激酶抑制剂)可以降低卡瑞珠单抗特异性反应性皮肤毛细血管内皮增生 (RCCEP) 的发生率。

文章亮点

    临床试验正在评估卡瑞珠单抗单药治疗、免疫治疗加靶向治疗、免疫检查点抑制剂加全身化疗以及持续免疫治疗的临床益处。

    未来的研究将侧重于识别和开发对晚期 HCC 中的 camrelizumab 有反应的可靠生物标志物。

ABSTRACT
Introduction

: Although many approaches have been used to treat hepatocellular carcinoma (HCC), the clinical benefits were limited, particularly for advanced HCC. However, recent treatments with PD-1/PD-L1 inhibitor monotherapy and its combination with other therapies, have demonstrated remarkable results. Camrelizumab, a selective, humanized, high-affinity IgG4 PD-1 monoclonal antibody, has been approved as a second-line treatment in patients with advanced HCC by NMPA in China.
Areas covered

: This paper introduces anti-PD-1/PD-L1 immunotherapies for advanced HCC and progresses to discuss the pharmacology, safety, and efficacy of camrelizumab in the treatment of advanced HCC. It also considers future research directions for camrelizumab in this setting.
Expert opinion

: The PD-1 binding epitope of camrelizumab is different from other PD-1 inhibitors. The IC50 and EC50 of camrelizumab for inhibiting the binding of PD-1 and PD-L1 is similar to pembrolizumab, is significantly lower than other PD-1 inhibitors, and has a higher affinity for PD-1 site. Camrelizumab exhibits a promising antitumor activity and an acceptable safety profile similar to other PD-1 inhibitors in advanced HCC. Apatinib (a VEGFR-2 tyrosine kinase inhibitor) can reduce the incidence of camrelizumab-specific reactive cutaneous capillary endothelial proliferation (RCCEP).

Article Highlights

    Clinical trials are evaluating camrelizumab monotherapy, immunotherapy plus targeted therapies, immune checkpoint inhibitors plus systemic chemotherapy, and clinical benefit of continued immunotherapy treatments.

    Future research will focus on the recognition and development of reliable biomarkers which respond to camrelizumab in advanced HCC.
