Description

用于延长药物半衰期的抗体、其融合蛋白和应用
技术领域
本发明属于治疗性抗体药领域,涉及一种用于延长药物半衰期和提高药物 生物利用率的抗体及其应用。
背景技术
大多数蛋白和多肽药物的半衰期很短,一是因为蛋白质药物会被体内的蛋 白酶降解而快速清除;二是由于肾小球的过滤作用使分子量小于60kDa的药 物在肾脏代谢中也易被清除。
现有技术中,尝试了各种方法延长药物体内半衰期,包括对分子结构进行 改造和缀合,然而各种分子设计都或多或少存在一些问题。以GLP-1(胰高血 糖样素-1)分子为例,天然的GLP-1在人体血循环中可以被二肽酶Ⅳ(dipeptidyl pepidiaseⅣ,DPPⅣ;CD26)迅速降解,其体内半衰期只有2-5分钟,不具 备成药性。采用氨基酸突变、赖氨酸残基脂肪链修饰、PEG化等技术可以达 到每天一次用药。已经上市的此类GLP-1类似物包括(1)艾塞那肽(商品名 Byetta)是第一个上市的GLP-1类似物,皮下注射,初始计量一次5ug,一天 两次;(2)利拉鲁肽(商品名Victoza/Saxenda)每日注射一次,每次注射 0.6mg-1.8mg;(3)利司那肽(商品名Lyxumia)起始剂量为10μg,每日一次, 应用14天,维持剂量:在第15天开始20μg为固定维持剂量,每日一次。上 述方法中,较为常用的方法是将多肽或蛋白质药物直接与化合物PEG相连形 成聚合物,然而这样会使药物的分子量变大,同时会增加药物的副作用。
在此基础之上研制的二代GLP-1类似物,采用HSA或Fc蛋白融合技术, 可以达到一周一次用药。例如,将多肽或蛋白质药物直接与人Fc区相连融合 表达的杜拉鲁肽(商品名:
Figure BDA0002383164600000011
)是由美国Lily公司研发的新型长效 GLP-1R激动药,由两个具有DPP-4抑制作用的GLP-1类似物和人免疫球蛋 白重链IgG4-Fc片段融合得到,其活性与内源性GLP-1相似,半衰期为5天, 能有效延缓肾脏的清除作用。FDA于2014批准的杜拉鲁肽皮下注射液上市。 每周给药一次,每次给药量0.75mg-1.5mg。然而与人Fc区融合表达的药物具 有引发ADCC、CDC的风险。另一种方法是将多肽或蛋白质药物直接与化合 物PEG相连形成聚合物,然而这样会使药物的分子量变大,同时会增加药物 的副作用。还有一种方法是将多肽或蛋白质药物直接与人血清白蛋白(Human Serum Albumin,HSA)相连融合表达。人血清白蛋白是人体血液中的主要蛋白, 该蛋白由585个氨基酸构成,是人体循环系统内的含量最多的可溶性蛋白,在 血液中的浓度为34~54g/L.白蛋白是最丰富的血浆蛋白,具有高度的可溶性, 非常稳定,能与人体内药物分子结合运输到体内各个部位发挥疗效。目前市场 上的阿必鲁肽(Albiglutide),是两个GLP-1分子串联后在C端连上改造后的人 血清白蛋白,建议给药量30毫克,每周一次。然而与人血清白蛋白融合表达 的药物分子量较大,不具有很好的细胞穿透性。
尽管目前市场上已有多种延长多肽或蛋白质药物半衰期的药物,但不是用 量大就是半衰期短,仍有必要进一步开发具有延长的药物半衰期,同时成本更 为低廉,患者依从性更好的药物结构。

1.产品结构与性质方面
与Fc区或完整HSA融合蛋白形式相比,本发明的抗体融合蛋白是新一代 GLP-1类似物。将GLP-1与本发明的抗体融合,具有分子量小,易穿过屏障 的优点,避免了Fc区融合蛋白具有的引发ADCC、CDC的风险。更为重要的 是,依照本发明所获得的融合蛋白相比其他改构形式具有更长的半衰期,前期 数据表明,半衰期能达到两周甚至更长。如背景技术所述,这样的半衰期相较 于目前的第一代和二代GLP-1类似物而言,半衰期大大提高,增加了患者服 药的方便性和依从性。同时,本发明获得的融合蛋白取得了相比类似治疗活性 的药物更高的生物利用率。
2制备工艺方面
本发明与现有的延长半衰期的技术相比,无需PEG修饰、微球释放、脂 肪酸修饰、掺入非天然氨基酸等复杂的技术工艺。并且,本发明的融合蛋白无 需担心翻译后修饰,特别是不需要糖基化,融合蛋白可以直接选用原核细胞如 大肠杆菌进行表达,而无需采用昂贵的哺乳动物细胞表达系统,制备工艺更为 简单,使成本大大降低。

.3抗HSA抗体库的构建与筛选
经过两轮PCR扩增得到大量目的片段后进行SfiI/NotI双酶切,使用商业 化T4DNA连接酶将酶切完成的目的片段连入噬菌体载体中,之后电击转入 TG1感受态。建库库容为1.07×108,随机挑取20个克隆进行测序,测序结果 分析显示,插入的片段皆为重链可变区片段,阳性率100%,包装成噬菌体库, 滴度为:2.15×1012pfu/ml。
采用固相筛选方法筛选噬菌体库。筛选流程是将靶分子包被在96孔表面 用,洗去未吸附的靶分子,然后封闭,之后用扣除背景的噬菌体抗体库加入到 孔中结合。洗去未结合的噬菌体,再用0.2M甘氨酸-盐酸洗脱得到亲和噬菌体。 每轮通过降低包被靶分子浓度和加大洗涤力度(本发明是减小靶分子浓度增加 洗液中吐温20浓度)得到高亲和力噬菌体。每经一轮淘选扩增试验,就会使 能与靶分子结合的抗体在噬菌体库中得到富集。
经过3轮筛选后富集达到1000倍以上,进行挑取单克隆验证。3轮筛选, 筛选结果如下:

实施例5融合蛋白的重组表达
将表达实施例4的氨基酸序列的DNA序列(其中编码nbHSA部分的DNA 序列如SEQID NO:48所示,GLP-1部分的DNA序列为本领域已知,可分别 从相应蛋白的Gengbank数据库获得,对于原始GLP-1的DNA序列可以参考 例如SEQ ID NO:71),利用NdeI/XhoI两个酶切位点,直接插入原核载体 PET30a(+)中,转化大肠杆菌,利用浓度1mM IPTG 37℃诱导表达,培养基为 LB培养基。Tris缓冲液进行包涵体清洗,8-25ml变性液溶解包涵体,复性液 中复性12-72h。阳离子或者阴离子树脂进行层析,随后凝胶层析(SDS-PAGE), 纯化目标蛋白。经过复性纯化后得到纯度不低于95%的样品,纯化后的电泳图 如图8所示。
变性液配方:3-6M盐酸胍或者4-8M尿素或者采用碱变性,氧化还原电 对(包括但不限于GSH/GSSG,胱氨酸/半胱氨酸等)Ph7.5-12。
复性液配方:(0-4M尿素,氧化还原电对(包括但不限于GSH/GSSG, 胱氨酸/半胱氨酸等)Ph7.5-10)。

将实施例5得到的7个样品中抗体端进行ELISA活性检测,用PH9.6包 被液稀释人血清,37℃静置包被,2%牛奶封闭。取13个样品用1%M-PBS 10 倍稀释混匀50μl/孔37℃静置1小时。一抗:用1%M-PBS按1:2000稀释 HRP-Etag 50μl/孔37℃静置1.0h。显色:取0.2MNa2HPO4+0.1M柠檬酸各4.5ml 加入少量OPD,60μl H2O2混匀,50μl/孔。2M硫酸终止50μl/孔,490nm检测。 结果见图6结果显示,每个样品中的抗体均呈现阳性。
实施例7实例1的融合蛋白GLP-1-nbHSA与多肽GLP-1的药效对比实验
购买雄性6-8周小鼠15只,禁食24小时,只供饮水,称重,分成5组; 合成多肽GLP-1与实例1样品GLP-1-nbHSA的浓度均用PBS稀释至1μg/ul; 第一组空白组注射100μlPBS;第二组注射0.55μg/100μl的纯GLP-1多肽;第 三组注射低剂量终浓度为0.26μg/100μl的实例1样品;第四组注射中剂量2.6μ g/100μl的实例1样品;第五组注射高剂量26μg/100μl的实例1样品。灌糖时, 灌糖后30分钟、45分钟、60分钟、90分钟之后抽血,用三诺安稳免调码血糖 仪测量数值,所有数值单位均是mMol/L(毫摩尔每升)。结果如表5所示: 实例1样品与GLP-1阳性对照比较有较好的药效。

实施例8实例1-7的融合蛋白GLP-1-nbHSA与多肽GLP-1的药效对比实验
利用实例1的数据作为参考,将多肽GLP-1和7个实例样品进行小鼠灌 糖实验,具体实验如下:购买雄性6-8周小鼠36只,禁食24小时,只供饮水, 称重,分成9组;合成多肽GLP-1与实例7个样品GLP-1-nbHSA的浓度均用PBS 稀释至1μg/μl;第一组空白组注射100μlPBS;第二组注射0.6μg/100μl的纯 GLP-1多肽;第三组注射低剂量终浓度为2.4μg/100μl的实例1样品;第四组 注射中剂量2.4μg/100μl的实例2样品;第五组注射高剂量2.4μg/100μl的实例 3样品;第六组注射中剂量2.4μg/100μl的实例4样品;第七组注射高剂量 2.4μg/100μl的实例5样品;第八组注射中计量2.4μg/100μl的实例6样品;第 九组注射高剂量2.4μg/100μl的实例7样品。
表6 7个实例在同一浓度下小鼠体内降糖效果
Figure BDA0002383164600000142
结果如表6所示:实例1样品与GLP-1阳性对照比较有较好的药效,所 有实例均有较好的降糖效果。
当然本发明中存在小鼠实验是用实例1的样品进行剂量摸索,这样得到的 是实例1的适合浓度,但从表6总体数据来看可以看出,所有实例均有较好得 降血糖作用。
实施例9猕猴降糖长效实验
购买8只糖尿病猕猴,一只用来进行空白对照;7只用来进行实验;实验 开始前3天每天对四只猕猴进行早餐前抽血,与早餐餐后2小时,早餐后4 小时抽血。记录血糖值,保证糖尿病猴血糖值稳定;根据猴体重与小鼠体重比 例进行剂量换算(换算方法见参考文献:实验动物与人用药量的新换算,熊远 珍,江西医学院学报,1997年04期),注射,给药量为130μg/kg。每隔4小 时进行采血测血糖,直至检测到血糖又恢复注射样品前值。再继续抽少量血液 进行持续检测,保证8只猕猴的血糖值又回升到初始糖尿病数值。结果见表7 以及图7。从结果中可以看到GLP-1多肽半衰期约2小时,而实例1-7最短半 衰期约9天最长可达2周甚至更长。
表7各个实例在猴子体内长效实验结果

以上数据表明,本发明的融合蛋白半衰期可达2周,并且在用量上会有所 减少,用量少,半衰期长,代表生物利用率高。而现有技术中已有药物半衰期 均在一周以内。例如,杜拉鲁肽:每周一次,初始计量0.75mg,以后增加到 去1.5mg;利拉鲁肽:每天给药一次,初始计量0.6后-增加到1.8mg;索马鲁 肽:每-周一次,初始剂量0.25毫克,后增至1毫克;阿比鲁泰:每周一次, 每次30毫克,后可增加至50毫克;他司鲁泰:皮下注射1次/周,目前正在进行3期临床;Tirzepatide:礼来正在进行2期临床研究,每周给药1次,皮 下注射;利西拉来:每天一次,10微克,15天后增加到20微克每天一次。
