登记简述

这项早期I期试验研究自体树突状细胞和一种名为Prevnar的疫苗联合免疫检查点抑制(使用贝伐珠单抗和阿替利珠单抗或度伐利尤单抗)在治疗接受标准高剂量外照射放疗后无法通过手术切除(不可切除)的肝癌患者中的副作用。自体树突状细胞是由患者自身白细胞生成的免疫细胞,在特殊实验室中培养并训练以刺激免疫系统摧毁肿瘤细胞。一种名为Prevnar的肺炎疫苗也可能有助于刺激免疫系统。贝伐珠单抗属于一类称为抗血管生成剂的药物。它通过阻止为肿瘤输送氧气和营养的血管形成来发挥作用。这可能减缓肿瘤的生长和扩散。使用单克隆抗体(如阿替利珠单抗和度伐利尤单抗)的免疫治疗可能有助于人体免疫系统攻击肿瘤,并可能干扰肿瘤细胞生长和扩散的能力。在放疗后给予自体树突状细胞和Prevnar联合免疫检查点抑制可能是安全且可耐受的,并可能刺激人体自身免疫系统对抗不可切除肝癌患者的肿瘤。

This early phase I trial studies the side effects of autologous dendritic cells and a vaccine called Prevnar in combination with immune checkpoint inhibition (with bevacizumab and atezolizumab or druvalumab) in treating patients liver cancer that cannot be removed by surgery (unresectable) after undergoing standard high-dose external beam radiotherapy. Autologous dendritic cells are immune cells generated from patients' own white blood cells that are grown in a special lab and trained to stimulate the immune system to destroy tumor cells. A pneumonia vaccine called Prevnar may also help stimulate the immune system. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Immunotherapy with monoclonal antibodies, such as atezolizumab and durvalumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving autologous dendritic cells and Prevnar in combination with immune checkpoint inhibition after radiotherapy may be safe, and tolerable and may stimulate the body's own immune system to fight against the tumor in patients with unresectable liver cancer.
