Description
本案是申请号为:201910086371.9,发明名称为:针对肿瘤靶向药物耐药位点的多肽疫苗及其设计方法的专利的分案。
技术领域
本发明涉及肿瘤疫苗领域,特别是一种针对肿瘤靶向药物耐药位点的多肽疫苗及其设计方法。
背景技术
近年来,肿瘤靶向治疗的进展随着分子生物学技术的发展和对发病机制从细胞、分子水平的进一步认识已经进入了一个全新的时代。这些领域的进展很快,迄今为止,很多靶向药物已经在临床起了极其重要甚至是奇迹般的作用。分子靶向治疗已成为外科、放化疗等肿瘤治疗的又一重要手段,在肿瘤治疗中发挥着越来越重要的作用。由于靶向治疗的高效率和低毒性,与传统的治疗和化疗相比,其优点是很明显的。靶向治疗发展迅速,有些已经按照循证医学的原则进入了国际肿瘤学界公认的标准治疗方案和规范。更多、更有希望的药物也在快马加鞭地研制和早期临床试验中。靶向药已成肿瘤治疗的一大利器。但是,随着治疗时间越来越长,多数患者出现耐药。至于耐药的具体机制,目前主要有3种。首先,通过基因突变产生耐药。基因检测阳性的患者约40%的基因会由原来基因产生新的基因,这会导致对原来的药物不敏感,从而产生耐药反应。其次,狡猾的癌细胞常常会“明修栈道暗度陈仓”,绕弯走另外一条路。这种情况在耐药患者中约占20%左右。除了以上两种耐药途径,剩下30%左右的患者的耐药机制,尚不明确。靶向后的“变身”(耐药)是不可避免的,几乎所有的靶向药物治疗都会出现耐药现象,其根本原因是由于癌细胞的异质性以及动态变化。目前一种靶向药物是针对癌细胞的某一个蛋白、某一个分子起作用,所以只能抑制肿瘤生长的一条通路而已。当一条通路受到抑制时,肿瘤细胞会自寻新的“生路”,选择其他通路合成自身生长所需要的物质,久而久之,分子靶向药物就失去了作用,从而产生耐药性,比如EGFR突变患者服用靶向药后出现耐药,50%~60%是因为再次发生基因突变,大多数突变为T790M突变,此时患者可以使用第三代靶向药物如奥斯替尼。大多数患者在接受EGFR-TKI治疗后的8-14个月会出现继发耐药,如何解决靶向药物治疗的耐药问题成为研究的热点。
近年来,由于肿瘤相关抗原和肿瘤特异性抗原的发现,以及人们对肿瘤诱导免疫应答和肿瘤逃避免疫监视机制的深入研究和理解,肿瘤多肽疫苗的研究已经取得了可喜的成就。新生抗原是基因突变导致的肿瘤细胞表面表达的异常蛋白,与常规抗原靶点不同的是新生抗原只在肿瘤细胞表面表达不在正常细胞表面表达且能被免疫系统识别并激活免疫系统。2017年7月13日,Nature杂志同一天发布了两项基于neoantigen的个性化肿瘤疫苗治疗恶性黑色素瘤的成功案例。德国的Carmen Loquai教授和türeci教授,利用neoantigen所对应的RNA做疫苗,一共治疗了13例病人。同一天,哈佛大学的CatherineJ.Wu教授带领的团队,利用neoantigen所对应的抗原肽做疫苗,也成功报道了治疗恶性黑色素瘤的案例。耐药位点多肽疫苗的一般设计流程,是找出导致靶向药物耐药的突变位点,分析出这些突变产生的新生抗原,制备能够被患者组织相容性复合体(MHC)特异识别的多肽疫苗,多肽制备既可以通过化学合成的方式获得,也可以使用核酸分子(例如DNA和RNA)通过转录和翻译的方式获得,或者也可以通过细菌或病毒为载体表达得到。将多肽疫苗注入患者体内,激活特异性T细胞应答和免疫风暴,使患者自身免疫系统能够有效识别、杀灭这一类带有耐药突变的肿瘤细胞。将多肽疫苗与靶向药联用一方面靶向药物可以对携带用药靶点的肿瘤细胞起到杀伤作用另一方面多肽疫苗激活的机体免疫系统可以在在耐药肿瘤细胞刚刚出现时就进行有效的识别并清除,从而延长靶向药物的作用时间,而且激活的免疫系统可以在体内长期保持对肿瘤细胞的杀伤作用,确保对耐药现象有持续的抑制性,在一定程度上克服由于耐药突变产生的靶向药物耐药性。市场需要一套针对肿瘤靶向药物耐药位点的多肽疫苗筛选和设计方法,可以有效降低肿瘤耐药发生概率,具有广谱性,缩短个体化多肽疫苗从分析到治疗的时间,降低医疗成本;本发明解决这样的问题。

具体实施方式
以下结合附图和具体实施例对本发明作具体的介绍。
针对肿瘤靶向药物耐药位点的多肽疫苗的设计方法,包括如下步骤:
1、靶向药物耐药突变数据收集:人类癌症相关体细胞突变目录Cosmic(数据库官网https://cancer.sanger.ac.uk/cosmic)对临床研究中的获得性耐药和原发性耐药的报道进行了整理和注释,包括基因、突变、药物,癌种及参考文献等信息。我们下载了FDA或者CFDA已批准的或处于临床试验III/IV期的所有靶向治疗药物耐药突变位点,对所有候选靶向药物和耐药突变尤其是支持的样本量较少的突变,进一步查找文献确定其可靠性,确定真正全面可靠的靶向药物耐药位点用于下游分析,例如cosmic收录有一条确定EGFR-T790M突变是奥斯替尼耐药位点的报道,但经过查找文献发现T790M不是奥斯替尼的耐药位点。
2、耐药突变多肽序列截取及MHC分子亲和力及免疫原性预测:
2.1、对于点突变截取覆盖突变位点上下游16个氨基酸的多肽序列,对于移码突变截取向前延伸16个长度的氨基酸、向后延伸直到终止密码子的多肽序列作为耐药突变位点的突变型多肽,同时截取相应位置对应的野生型多肽序列。
2.2、统计高频HLA分型及频率:高频HLA的来源主要有两部分,一是来自公共数据库的统计(IMGT/HLA及中华骨髓库),结合近年文献报道的信息,汇总了中国人群比较常见的HLA等位基因分型;二是从临床患者的数据库中统计了出现频率比较高的一组HLA分型,具体的数据库如表2所示。将两组HLA合并去重之后作为用于预测的候选HLA分型。需要说明的是,数据库的选择不受限制,这只是一种优选实施例,也可以是其他几种数据库的组合统计。
2.3、我们使用netMHCpan、netMHC及Pickpocket三款软件分析了这些突变位点对应的多肽与2.2步中得到的HLA分子结合亲和力综合三款软件将亲和力分为三类(强亲和力-SB、弱亲和力-WB和无亲和力),并与相对野生型多肽比较确定其亲和力变化(由无亲和力变为有强亲和力定义为A类变化、由无亲和力变为弱亲和力定义为B类变化、由弱亲和力变为强亲和力定义为C类变化、其它无变化的定义为D类变化,内部排序认为A类优于B类优于C类优于D类),另外还使用IEDB提供的免疫原性预测工具预测其免疫原性,保留突变型多肽亲和力强、亲和力变化大并且免疫原性强的表位,共筛选得到31种靶向药物对应的137个耐药突变。
3、靶向药物与耐药位点相互关系及药物聚类:3.1对耐药位点亲和力打分:综合考虑位点有亲和力的表位个数及各表位亲和力变化大小(a.对A、B、C、D四类不同亲和力变化给予不同的权重,b.根据每个表位对应的HLA频率大小给予权重,c.将位点的各表位累加求和)。 AC:亲和力变化大小,A、B、C、D四类不同亲和力变化给予不同的权重;Fhla:对应的HLA频率;n:位点的各表位个数;
3.2使用cytoscape对所有的靶向药物及耐药位点作网络图(如图1),耐药位点的大小代表其亲和力得分数,综合分析靶向药物和耐药位点间相互关系结合靶向药物作用机制对靶向药物聚类从而将其分为7类如图1所示。第一类针对SMO突变产生耐药的Hedgehog信号通路拮抗剂维莫德吉,第二类针对BTK突变产生耐药的依鲁替尼,第三类针对AR耐药突变的一些抗雄激素类药物如阿比特龙等,第四类针对BRAF耐药突变的一些菲尼类药物,第五类针对ALK、MET等融合基因的一些络氨酸激酶抑制剂,第六类针对EGFR通路的络氨酸激酶抑制剂,第七类针对PI3K/AKT/mTOR通路的依维莫司等激酶抑制剂。由于以上靶向药物聚类综合考虑了药物作用机制和与耐药位点之间的相互关系,将有相似作用机制和交叉耐药位点的靶向药物聚为一类,从而最大化的覆盖靶向药物的有免疫原性的耐药位点,并且可以显著降低由于患者自身HLA分子差异导致的“脱靶”现象,从而使得多肽疫苗可以最大范围内的对有类似耐药突变的肿瘤细胞起到杀伤作用,相对单药疫苗显著提高了其有效性。
4、多肽疫苗序列设计:作为一种实施例,可以通过人工设计相对应的疫苗多肽序列,也可以输入我们自主研发的疫苗设计程序iNeo-VaDes(V1.2),设计多肽疫苗序列。作为一种针对靶向药物耐药的多肽疫苗疗法,在疫苗多肽设计过程中,本发明考虑了抗原表位分布,尽可能多的覆盖含有突变位点的表位,另外还考虑多肽的长度、疏水率等影响氨基酸合成效率的因素,以及多肽的毒性、同源性等影响多肽安全性的因素。本发明的疫苗多肽组合由包含以下137个突变的多肽序列组成,具体如下表1所示。5、疫苗制备:多肽疫苗的制备既可以直接使用化学合成的方式制备,也可以使用核酸分子(例如DNA和RNA)通过转录和翻译的方式获得,或者也可以通过细菌或病毒为载体表达得到。在本例中我们使用化学合成方式获得多肽疫苗。

△本发明提供了31个靶向药物的多肽疫苗,基本覆盖常见肿瘤靶向药物,用以下实验对各个多肽的免疫原性进行实验验证:
实验1,多肽的免疫原性测定;实验目的:通过ELISpot实验,验证本发明中7个产品对应的多肽在人源化小鼠体内均能引起免疫反应。实验方法:实验多肽:7个产品多肽由南京金斯瑞生物科技有限公司代合成,多肽纯度均大于90%,内毒素含量低于0.5EU/mg。为了检测多肽的免疫反应,实施IFN-γ酶联免疫吸附(ELISPOT)测定法。详细的实验过程如下:选用8周龄人源化小鼠B-NSG(CD34+)24只,随机分为8组,每组3只。适应一周后,分为多肽组1(对应产品1)、多肽组2(对应产品2)、多肽组3(对应产品3)……多肽组7(对应产品7),共计7组及阴性对照组编号8。采用CpG为佐剂(0.2μg/只),多肽50μg每只,再与弗氏不完全佐剂Freund’s adjuvant(FIA,Sigma-Aldrich)1:1混匀,乳化30分钟,PBS与弗氏不完全佐剂1:1混合乳化30分钟作为阴性对照,四次于颈背部右胸皮下免疫,总剂量0.5mL/只,1周一次,共三周,第三次免疫后10天,取的小鼠脾脏,制备小鼠淋巴细胞悬液,用于ELISPOT检测。ELISPOT检测结果中,IFN-γ呈阳性结果的多肽,即判定为阳性候选多肽。实验按组别分别进行单肽有ELISPOT试验,即将小鼠淋巴细胞稀释成浓度为1-2*106/mL,铺24孔板,每孔1mL,分为对照组(与多肽相同浓度的DMSO)、相应的单条多肽组,PHA阳性对照组编号(PHA组淋巴细胞来源于阴性对照组),每个处理重复3次(即3个复孔),分别加入相应的多肽(10μg/mL),预孵育72h后离心分离细胞,调整细胞浓度为2*106/mL,上IFN-γElispot板,按照IFN-γELISPOT试剂盒的说明书方法进行显色,运用CTL-ImmunoSpotS5系列酶联斑点分析仪读取产生的斑点数。IFN-γ阳性结果表明有抗原特异性T细胞产生,视为多肽能引起机体的免疫反应,斑点数的多少反映其免疫的强弱。
实验结果:为了进一步明确了各个单独多肽的免疫反应,分别进行了各个多肽组中其相应的单肽的ELISPOT实验,各多肽产生的斑点数见图2A-D,各个均能引起免疫反应,但各个多肽产生的斑点差异比较大,从10个斑点到200多个斑点不等,而对照组基本无斑点产生。结果分析:本发明中7个产品对应的多肽在人源化小鼠体内均能引起免疫反应。
实验二,验证本发明中7类靶向药物的耐药多肽疫苗的治疗及预防效果;
为了验证本发明中胃癌耐药多肽疫苗的治疗及预防效果,因此需要构建一套含本发明中特定突变位点的稳转细胞系,针对7类靶向药物分别进行如下7个实施例的实验准备;实施例1,第一类针对SMO突变产生耐药的Hedgehog信号通路拮抗剂维莫德吉(Vismodegib)的特定突变位点的稳转细胞系的构建:Vismodegib购于LC Laboratories,胃癌细胞株系AGS购于ATCC,FITC-CD44购于BD公司(BD555478)。细胞的制备:胃癌细胞株系AGS于含有10%FBS,100U/mL penicillin和100μg/mL streptomycin,2mmol/L l-glutamine的DMEM培养48h,换液并补加20ng/mL of EGF,bFGF,N-2(1×),和B27,继续培养72h,促进其形成椭球体(“spheroid formation media”)。椭球体经Accutase(InnovativeCell Technologies)酶解形成单细胞,用FITC-CD44流式抗体进行分选出阳性细胞作为后续的转染细胞,记为CD44+-AGS。
实验目的:为了验证本发明中胃癌耐药多肽诱导的T细胞具有杀伤活性,因此需要构建一套含本发明中特定突变位点的稳转细胞系,能够表达递呈这些多肽。a.构建突变位点真核表达质粒:采用人工合成的方法获得能够表达本发明中突变的全部15条疫苗多肽的mini-gene,由以下几部分组成:信号肽部分(lysosome-associated membraneglycoprotein 1,LAMP1),15条突变多肽和MHC class I trafficking domain(MITD),15条突变多肽之间用柔性连接肽GGSGGGGSGG连接,基因进行密码子优化后,上游引入GATATC(EcoR V),下游引入CTCGAG(Xho I),将其克隆到真核表达载体pcDNA3.1-hygro(+)中,命名为smo15-pcDNA3.1(+)。同时合成相应野生型多肽作为对照(由于其中相邻的多肽可归到一条野生型长肽,故总共有7条野生型多肽),命名为smow7-pcDNA3.1(+)。所有基因片段由南京金斯瑞生物科技有限公司代合成和构建,smo15的氨基酸序列为:SEQ ID:NO 6所示;Smow7的氨基酸序列为:SEQ ID:NO 7所示;其中第1-28个氨基酸为信号肽区域,用加粗斜体表示;下划线标注部分为MITD序列;
