Oncotarget:Elenagen疫苗在晚期实体瘤治疗中表现安全性和抗肿瘤活性,并能恢复肿瘤对化学疗法的敏感性

2017-06-02 MedSci MedSci原创

Elenagen在晚期的实体瘤中表现出良好的安全性和抗肿瘤活性,而该项研究中另一特别令人鼓舞的方面是其还能恢复肿瘤对化学疗法的敏感性。

Elenagen是一种编码p62/SQSTM1的质粒,其第一类DNA疫苗具有两个相互补充的作用机制:能够引发针对p62的免疫应答并能缓解全身的慢性炎症。在以前对啮齿动物肿瘤模型和犬的自发性肿瘤研究中,Elenagen就表现出安全性和抗肿瘤功效。

目前的这项联合研究评估了Elenagen在晚期癌症的人类患者中的安全性和临床活性。研究中有15例患者接受不断增加剂量(每剂量1-5mg,每周5次)的Elenagen治疗,另外12例患者接受1mg剂量的Elenagen治疗。他们中10例患有乳腺癌卵巢癌患者在Elenagen治疗后进行常规化学疗法治疗。其中,患有乳腺癌、卵巢癌、肺癌、肾癌和黑色素瘤的12例患者(44%)病情达到稳定超过8周,并且其中4例(15%)患者的肿瘤得到控制超过24周,甚至最多的达到32周。在Elenagen治疗后用常规化学疗法治疗的乳腺癌和卵巢癌患者获得了额外的12-28周的肿瘤稳定。

Elenagen在晚期的实体瘤中表现出良好的安全性和抗肿瘤活性,而该项研究中另一特别令人鼓舞的方面是其还能恢复肿瘤对化学疗法的敏感性。

JCI Insight:调节机体免疫系统抵御癌症 新型癌症疫苗或有望被开发

图片来源:medicalxpress.com 近日,一项发表于国际杂志Journal of Clinical Investigation的研究论文中,来自澳洲莫纳斯大学和昆士兰大学的研究人员开发了一种新方法,该方法可以调节机体免疫系统来抵御疾病,该研究或为后期开发癌症疫苗及其它疾病的新型疗法提供思路。 文章中,研究者主要对树突细胞进行研究,树突细胞是免疫系统中的一种岗哨细胞,其可以识别死亡

Cancer Immunol Immun:新型癌症疫苗来了!可治疗胶质母细胞瘤

胶质母细胞瘤是一种常见的恶性原发性脑部肿瘤,尽管标准疗法在不断改进,但是患者的生存中值仍然仅为大约15个月,如果不进行治疗患者的生存中值只为4个月;近日,来自托马斯杰斐逊大学的科学家开发了一种新型癌症疫苗,其可以通过激活患者机体免疫系统抵御脑瘤来延长患者的寿命,相关研究刊登于国际杂志Cancer Immunology,Immunotherapy上,该研究或为开发治疗恶性胶质瘤的新型实验性疗法提

Cell Rep:中国科学家基于多孔硅微粒技术开发出了新型癌症疫苗

近日,发表于国际杂志Cell Reports上的一篇研究报告中,来自中国华中科技大学等处的科学家们通过研究表明,当将癌症抗原装载入硅微粒就可以大幅度提高癌症疫苗的效力;很多研究都揭示了装载抗原HER2的微粒不仅可以保护抗原免于过早被破坏,同时也可以刺激免疫系统识别并且攻击过表达HER2抗原的癌细胞。研究者Haifa Shen博士表示,仅需要向动物模型注射一个剂量的癌症疫苗或许就可以完全抑制肿瘤的生

Merck被曝用印度儿童测试癌症疫苗

据英国《每日邮报》1月12日报道,印度最高法院文件显示,欧美制药公司利用9岁印度孩童当作“试药小白鼠”测试新型抗宫颈癌疫苗,导致许多孩子出现副作用,包括恶心、头晕以及体重减轻等。这些孩子根本不知道自己参加疫苗测试,她们显然受到欺骗。但参与测试的医生表示,参与者充分知情。制药公司也否认存在任何错误。 美国默克集团(Merck)研发的Gardasil 9抗宫颈癌疫苗刚刚获得美国批准上市,并将于今年在

Cell Reports:癌症疫苗新型佐剂探索

癌症免疫疗法是目前临床癌症治疗中的新型潮流。FDA最近批准了针对转移性前列腺癌的树突状细胞免疫疗法以及利用免疫抑制阻断型抗体PD-1,CTLA-4的免疫检查点疗法。尽管有这些突破,目前的癌症免疫疗法还是存在诸多限制。比如肿瘤疫苗释放效率低下,肿瘤组织特异性抗原的交叉呈递受阻,一系列的免疫抑制性细胞因子的作用,等等。 先天免疫是抗肿瘤免疫的重要组成部分,因此介导先天免疫与后天免疫的信号分子能够
