Definitions

  • the invention particularly relates to antibody drug conjugates, intermediates (toxins with linkers), methods of preparation, pharmaceutical compositions and uses.
  • a typical antibody drug conjugate comprises a monoclonal antibody that binds to a cancer cell surface specific antigen.
  • These antibodies include proteins on the surface of immune system B cells and T cells, such as CD20, CD22, and human epidermal growth factor receptor 2 (Her2) and prostate specific membrane antigen (PSMA). These specific antibodies are linked to highly toxic drugs via a cleavable linker. Such drugs are designed to cause cancer cell death by inducing irreversible DNA damage or interfering with cell division.
  • ADCs antibody drug conjugates
  • the first antibody drug conjugate approved by the FDA is Melota (Gentuzumab/Ozomib) developed by Wyeth in the United States for the treatment of acute myeloid leukemia in 2000, but due to some adverse effects As well as security considerations, the drug was withdrawn 10 years after its launch. Since then, the technology for attaching antibodies to drugs has made great progress. Using a linker with a suitable biological half-life, the researchers were able to ensure that the antibody drug conjugate reached the target cell and reduced its side effects.
  • Kadcyla (trastuzumab emtansine, T-DM1) was approved for the treatment of metastatic breast cancer.
  • Kadcyla combines the antibody Herceptin, which treats breast cancer, with the toxin, which is licensed by ImmunoGen. The drug's 2015 sales were nearly $700 million.
  • Antibody drug conjugates are likely to be the next blockbuster drug to bring a sustainable source of income.
  • the synergy between biomedicine and clinical trials has led to the continued success of the antibody drug conjugate technology platform.
  • These common results indicate the use of humanized monoclonal antibody technology as a target-directed therapeutic administration effort.
  • most of the antibody drug conjugates in development have used the aristatins of Seattle Genetics or the maytansinoid of ImmunoGen as effective toxins.
  • companies such as Spirogen are also developing other toxins for the next generation of antibody drug conjugates, such as PBD.
  • Maytansinoid alkaloids were first isolated from East African shrubs, F. sylvestris (US 389611, JP 01006282, JP 63233986), and are a class of highly cytotoxic compounds as anticancer agents. Many of the maytansinoid derivatives prepared by people have high anticancer activity, which is 100 to 1000 times that of the traditional anticancer drug vinblastine or paclitaxel. (J. Med. Chem., 1978, 21, 31-37, Chem. Pharma. Bull., 1984, 3441-3451, J. Med. Chem. 2006, 49, 4392-4408, Chem. Pharm. Bull. 2004 , 52(1) 1-26, WO2011039721, WO2012/061590, WO2014/094453).
  • the maytansinoid analogs DM1 and DM4 are reported by Chari, R. V. J. et al. in the patents US Pat. No. 5,208,020, US Pat. No. 5,416,064 and J. Med. Chem, 2006, 49, 4392-4408.
  • Patents WO2004/103272, EP0425235 report conjugates of maytansin analogs DM1 and DM4 and their anticancer activity.
  • a typical antibody drug conjugate consists of a drug, a linker unit and an antibody.
  • the choice of specific antibodies and drugs depends on the particular disease and has a significant impact on the safety and efficacy of the conjugate.
  • the stability of the ligation unit and the method of coupling to the antibody play a decisive role in the development of the ADC drug.
  • Factors that determine the efficacy of antibody drug conjugates include the stability of the linker unit and its cleavage sensitivity, cell surface internalization, transport, and release of cytotoxin.
  • T-DM1 which readily degrades and releases toxins before endocytosis of antigen binding protein (Abu), causes side effects.
  • the ratio of the drug/antibody obtained by coupling with the antibody is low and the distribution changes are relatively large, and it is difficult to accurately control the efficacy and safety (WO2012/061590A1, WO201139721). Therefore, it is an urgent technical problem to find an antibody drug conjugate with high stability, good water solubility and high cytotoxin release efficiency, specificity, high cytotoxicity and good anticancer effect.
  • the technical problem to be solved by the present invention is to overcome the poor stability, low cleavage sensitivity of the antibody drug conjugate linking unit in the prior art, low cell cell surface internalization, transport and cytotoxic release efficiency, poor cytotoxicity, specificity

Description

抗体药物偶联物、中间体、制备方法、药物组合物及应用
本申请要求申请日为2015年6月9日的中国专利申请CN201510313585.7的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明具体涉及抗体药物偶联物、中间体(带连接体的毒素)、制备方法、药物组合物及应用。
背景技术
典型的抗体药物偶联物(ADC)包含能够与癌细胞表面特异性抗原相结合的单克隆抗体。这些抗体包括免疫系统B细胞和T细胞表面的一些蛋白，比如CD20、CD22以及人表皮生长因子受体2(Her2)和前列腺特异性膜抗原(PSMA)。通过一个可裂解的连接单元将这些特异性抗体与强毒性药物进行连接。设计这样的药物通过诱导不可逆的DNA损伤或者干扰细胞分裂，进而导致癌细胞的死亡。
抗体药物偶联物(ADC)的作用机理是通过抗体识别并与特异性抗原结合，引发一系列反应，进而通过细胞内吞进入细胞质内，溶酶体酶将强毒性药物释放杀死癌细胞。相比传统化疗对正常组织的无差别损伤，通过靶向给药，可以使药物直接作用于癌细胞，减少了其对正常细胞的损害。
FDA批准上市的第一个抗体药物偶联物是美国惠氏2000年研发的用于治疗急性粒细胞性白血病的麦罗塔(吉妥珠单抗/奥佐米星)，但由于一些不良的效果以及处于安全方面的考虑，该药物在上市十年后被撤回。此后，将抗体和药物连接的技术取得了很大的进步。使用具有合适生物半衰期的连接子，研究人员得以确保抗体药物偶联物可以到达目标细胞从而减少其副作用。
2011年，美国FDA批准了Seattle Genetics的Adcetris(brentuximab vedotin)，用于治疗霍奇金氏淋巴瘤和系统性间变性大细胞淋巴瘤。该抗体药物偶联物在2012年第一季度的销售额高达$34，500，000并且收入持续在增加。预计在接下来的十年里面仅肿瘤治疗药品市场，抗体药物偶联物的使用将比过去增长50％左右。目前罗氏(Roche)和基因泰克(Genentech)一起有25个以上的抗体药物偶联物在研发中，其中有9个正在进行临床研究。
2013年2月第一个抗体药物偶联物潜在的重磅炸弹Kadcyla上市，Kadcyla(trastuzumab emtansine,T-DM1)被批准用于转移性乳腺癌的治疗。Kadcyla将治疗乳腺癌的抗体赫赛汀与ImmunoGen许可使用的毒素美坦新组合在一起。该药物的2015年销售额近7亿美元。
抗体药物偶联物很可能将成为下一个带来持续收入源的重磅炸弹级药物领域。生物医药和临床试验相互配合带来了抗体药物偶联物技术平台的持续成功。这些共同的结果表明使用人源化单克隆抗体技术作为靶标导向的治疗性给药的努力。目前为止，研发中的大部分抗体药物偶联物使用Seattle Genetics的auristatins或ImmunoGen的美登素类作为有效毒素。此外，Spirogen等公司也在为下一代抗体药物偶联物开发其他的毒素，比如PBD类。
美登素类生物碱首先是由东非灌木齿叶美登木(US 389611，JP 01006282，JP 63233986)中分离得到，作为抗癌试剂，是一类高度细胞毒性的化合物。人们制备得到的很多美登素类衍生物具有很高的抗癌活性，是传统抗癌药物长春碱或紫杉醇的100到1000倍。(J.Med.Chem.,1978,21,31-37,Chem.Pharma.Bull.,1984,3441-3451,J.Med.Chem.2006,49,4392-4408,Chem.Pharm.Bull.2004,52(1)1-26,WO2011039721,WO2012/061590,WO2014/094453).
在专利US 5208020,US,5416064和J.Med.Chem,2006,49,4392-4408中，Chari,R.V.J.等人报道了美登素类似物DM1和DM4。专利WO2004/103272,EP0425235报道了美登素类似物DM1和DM4的偶联物以及他们的抗癌活性。之后的一系列文章和专利中报道了许多美登素类似物的偶联物作为抗癌药物(WO 2011/039721,WO2012/061590,WO2014/134483,WO2014/134457,WO2014/194030,WO2014/134486,WO2014/094355,WO2015/000062,WO2014/145090,WO2013/173391)。
典型的抗体药物偶联物由药物、连接单元和抗体三部分组成。特异性抗体和药物的选择取决于特定疾病，并对偶联物的安全性和有效性有重要影响。而连接单元的稳定性以及偶联到抗体的方法对ADC药物的开发结果具有决定性的作用。决定抗体药物偶联物疗效的因素包括连接单元的稳定性及其断裂敏感性，细胞表面激发内化、转运和细胞毒素的释放。
Figure PCTCN2016085275-appb-000001
例如T-DM1，其容易在抗原结合蛋白(Abu)内吞之前过早降解并释放毒素，引起副作用。而且其与抗体偶联得到的药物/抗体比例较低而且分布变化比较大，药效和安全性精确控制的难度较大(WO2012/061590A1，WO201139721)。因此，寻找稳定性高,水溶性好的连接体，进而得到细胞毒素的释放效率高、特异性好、细胞毒性高、抗癌效果好的抗体药物偶联物是目前急需解决的技术问题。
发明内容
本发明所要解决的技术问题是为了克服现有技术中抗体药物偶联物连接单元的稳定性差、断裂敏感性低，细胞表面激发内化、转运和细胞毒素的释放效率低、胞毒性差，特异性差，副作用大等缺陷，而提供了一种抗体药物偶联物、中间体(带连接体的毒素毒素)、制备方法、药物组合物及应用。本发明的抗体药物偶联物，具有非常高的细胞毒性，抗癌效果好，具有良好的市场应用前景。
