Definitions

  • This application belongs to the field of biomedicine, and relates to a combined pharmaceutical composition for the treatment of small cell lung cancer.
  • Tyrosine kinases are a group of enzymes that catalyze the phosphorylation of protein tyrosine residues. They play an important role in intracellular signal transduction. They are involved in the regulation, signal transmission and development of normal cells, and are also related to tumor cells. Proliferation, differentiation, migration and apoptosis are closely related. Many receptor tyrosine kinases are related to the formation of tumors, and can be divided into epidermal growth factor receptor (EGFR), platelet-derived growth factor receptor (PDGFR), and vascular endothelial cell growth factor receptor according to the structure of their extracellular region. Body (VEGFR), Fibroblast Growth Factor Receptor (FGFR), etc.

  • PD-L1 (Programmed death-ligand l), also known as CD247 and B7-H1, is a ligand of programmed death molecule l (Programmed death, PD-1).
  • PD-L1 is highly expressed on the surface of a variety of tumor cells, and the degree of tumor malignancy and poor prognosis are closely related to the expression level of PD-L1.
  • PD-L1 on the surface of cancer cells binds to PD-1 or CD80 on the surface of T cells to inhibit the activation and proliferation of T cells, promote effector T cells into a state of exhaustion or anergy, and induce T cell growth.
  • Apoptosis stimulates the differentiation of helper T cells into regulatory T cells, thereby preventing T cells from killing tumor cells.
  • Anti-PD-L1 antibody can block the interaction of PD-L1 with PD-1 and CD80, so that related negative regulatory signals cannot be initiated and transmitted, thereby avoiding the inhibition of effector T cell activity in the tumor microenvironment , So that T cells can play the role of killing and inhibiting tumor cells. Because anti-PD-L1 antibody can directly act on tumor tissues, it has high specificity and safety.

Description

治疗小细胞肺癌的联用药物组合物 技术领域
本申请属于生物医药领域，涉及治疗小细胞肺癌的联用药物组合物。
背景技术
酪氨酸激酶是一组催化蛋白质酪氨酸残基磷酸化的酶，在细胞内的信号转导中起着重要的作用，它参与正常细胞的调节、信号传递和发育，也与肿瘤细胞的增殖、分化、迁移和凋亡密切相关。许多受体酪氨酸激酶都与肿瘤的形成相关，根据其细胞外区域结构的不同可分为表皮生长因子受体(EGFR)、血小板衍化生长因子受体(PDGFR)、血管内皮细胞生长因子受体(VEGFR)、成纤维细胞生长因子受体(FGFR)等等。
PD-L1(Programmed death-ligand l)又称为CD247和B7-H1，是程序性死亡分子l(Programmed death,PD-1)的一个配体。PD-L1在多种肿瘤细胞表面高表达，而且肿瘤的恶性程度以及不良预后与PD-L1的表达水平密切相关。在肿瘤微环境中，癌症细胞表面的PD-L1通过与T细胞表面的PD-1或CD80的结合，抑制T细胞的激活和增殖，促进效应T细胞进入衰竭或无反应状态，诱导T细胞的凋亡，刺激辅助T细胞分化成为调节性T细胞，从而阻止T细胞对肿瘤细胞的杀伤作用。抗PD-L1抗体可以通过阻断PD-L1与PD-1及CD80的相互作用，使得相关的负调控信号不能被启动与传导，从而避免了在肿瘤微环境中的效应T细胞的活性被抑制，使T细胞可以发挥杀伤和抑制肿瘤细胞的功能。由于抗PD-L1抗体能够直接作用于肿瘤组织，因而具有较高的特异性和安全性。
小细胞肺癌(small cell lung cancer，SCLC)是肺癌中恶性程度最高的一种类型，具有进展快、转移早、易复发等特点，约占新发肺癌15％-20％，其发生与长期吸烟有密切关系；SCLC未经治疗者的中位生存期(median survival time，MST)仅为2个月-4个月；治疗后，局限期患者的MST约为15个月-20个月，广泛期患者的MST为8个月-13个月。同其它类型肺癌相比，SCLC对化疗和放疗比较敏感，然而，由于存在高复发率和耐药率，因此在治疗方面仍然面临诸多挑战(小细胞肺癌的诊疗进展，《中国肺癌杂志》，2011年10月，第14卷第10期，第819-824页)。
WO2016022630公开了一类PD-L1抗体，对PD-L1具有较高的亲和力，能够显著抑制细胞表面的PD-L1和PD-1的相互作用，并显著促进T细胞分泌IL-2和INF-γ。
尽管对增殖性疾病(癌症)患者而言有许多治疗选择，仍需要更为有效的治疗剂以供临床使用，尤其是一种以上药物的组合使用。

本申请提供了结合PD-L1的分离的抗体或其片段，其中所述抗体可以由杂交瘤产生，所述杂交瘤选自由本文称为13C5、5G11的杂交瘤组成的组。因此，本申请还包括杂交瘤13C5、5G11，以及产生本文公开的抗体的任何杂交瘤。本发明还提供了编码本文提供的抗体和其片段的分离的多核苷酸。本发明还包括包含分离的多核苷酸的表达载体，和包含所述表达载体的宿主细胞。
术语“分离的抗体”表示这样的抗体：其基本上不含有具有不同抗原特异性的其它抗体(例如，分离的特异性地结合PD-1的抗体基本上不含有特异性地结合除PD-1以外的抗原的抗体)。但是，分离的特异性地结合PD-1的抗体可以具有与其它抗原(诸如来自不同物种的PD-1分子)的交叉反应性。此外，分离的抗体可以基本上不含有其它细胞材料和/或化学物质。
术语“单克隆抗体”(“mAb”)表示单一分子组成的抗体分子(即，这样的抗体分子：其基本序列是基本上相同的，并且其表现出对特定表位的单一结合特异性和亲和力)的非天然存在的制备物。mAb是分离的抗体的一个例子。通过本领域技术人员已知的杂交瘤技术、重组技术、转基因技术或其它技术，可以生产mAb。
本文公开的抗体和其抗原结合片段对PD-L1是特异性的。在一个实施方案中，抗体或和其片段对PD-L1是特异性的。在一个实施方案中，本文提供的抗体和片段结合人或灵长类动物PD-L1，但不结合来自任何其它哺乳动物的PD-L1。在另一个实施方案中，抗体或和其片段不结合小鼠PD-L1。术语“人PD-L1”、“hPD-L1”和“huPD-L1”等在本文中可互换使用，并且是指人PD-L1和人PD-L1的变体或同种型。“特异性”意指抗体和其片段以比任何其它靶标更大的亲和力结合PD-L1。
术语“治疗”一般是指获得需要的药理和/或生理效应。该效应根据完全或部分地预防疾病或其症状，可以是预防性的；和/或根据部分或完全稳定或治愈疾病和/或由于疾病产生的副作用，可以是治疗性的。本文使用的“治疗”涵盖了对患者疾病的任何治疗，包括：(a)预防易感染疾病或症状但还没诊断出患病的患者所发生的疾病或症状；(b)抑制疾病的症状，即阻止其发展；或(c)缓解疾病的症状，即，导致疾病或症状退化。
术语“有效量”意指(i)治疗或预防特定疾病、病况或障碍，(ii)减轻、改善或消除特定疾病、病况或障碍的一种或多种症状，或(iii)预防或延迟本文中所述的特定疾病、病况或障碍的一种或多种症状发作的本申请化合物的用量。构成“治疗有效量”的活性物质(例如本申请的抗体或化合物)的量可根据一些因素而变化，诸如个体的疾病状态、年龄、性别和重量，以及治疗剂或治疗剂组合在个体中引发所需应答的能力。有效量也可例行性地由本领域技术人员根据其自身的知识及本公开内容而确定。
术语“施用”表示，使用本领域技术人员已知的多种方法和递送系统中的任一种，向主体物理引入包含治疗剂的组合物。免疫检查点抑制剂(例如，抗PD-1抗体或抗PD-L1抗体)的施用途径包括静脉内、肌肉内、皮下、腹膜内、脊柱或其它胃肠外施用途径，例如通过注射或输注。本文中使用的短语“胃肠外施用”是指，通常通过注射进行的除了肠内和局部施用以外的施用模式，且包括但不限于，静脉内、肌肉内、动脉内、鞘内、淋巴管内、病灶内、囊内、眶内、心内、真皮内、腹膜内、经气管、皮下、表皮下、关节内、囊下、蛛网膜下、脊柱内、硬膜外和胸骨内注射和输注、以及体内电穿孔。在某些实施方案中，所述免疫检查点抑制剂(例如，抗PD-1抗体或抗PD-L1抗体)通过非胃肠外途径施用，在某些实施方案中，口服施用。其它非胃肠外途径包括局部、表皮或粘膜施用途径，例如，鼻内地、阴道地、直肠地、舌下地或局部地。还可以执行施用，例如，一次、多次，和/或在一个或多个延长的时间段中。
术语“剂量”的应用是指，不考虑患者的重量或体表面积(BSA)施用给患者的剂量。例如，60kg人和100kg人将接受相同剂量的抗体(例如，240mg抗PD-1抗体)。
本文提及的术语“基于重量的剂量”是指基于患者的重量计算出的、施用给患者的剂量。例如，当具有60kg体重的患者需要3mg/kg的抗PD-1抗体时，人们可以从抗PD-1抗体的固定剂量制剂中一次性抽取适当量的抗PD-1抗体(即，180mg)。
安罗替尼可通过多种途径给药，该途径包括但不限于口服、肠胃外、腹膜内、静脉内、动脉内、透皮、舌下、肌内、直肠、透颊、鼻内、经吸入、阴道、眼内、经局部给药、皮下、脂肪内、关节内、腹膜内和鞘内。在一些特定的实施方案中，通过口服给药。给予安罗替尼的量可根据疾病的严重程度、疾病的响应、任何治疗相关的毒性、患者的年龄和健康状态来确定。例如，给予安罗替尼的日剂量可为2毫克至20毫克，在一些实施方案中，给予安罗替尼或其药学上可接受的盐的日剂量可为2、3、4、5、6、7、8、9、10、11、12、13、14、15和16毫克。安罗替尼可以每日施用一次或多次。在一些实施方案中，安罗替尼以口服固体制剂每天给药一次。
安罗替尼的给药方案可根据药物的活性、毒性以及患者的耐受性等来综合确定。优选地，以间隔给药的方式给予安罗替尼。所述的间隔给药包括给药期和停药期，在给药期内可以每天一次或多次给予安罗替尼。例如给药期和停药期的以天数计的比值为2:0.5～5，优选2:0.5～3，较优选2:0.5～2，更优选2:0.5～1。在一些实施方案中，连续给药2周停药2周。在一些实施方案中，连续给药2周停药1周。在一些实施方案中，连续给药5天停药2天。例如安罗替尼可以每日一次6mg、8mg、10mg或者12mg的剂量口服给药，连续用药2周，停1周的给药方式给药。
术语“药学上可接受的”，是针对那些化合物、材料、组合物和/或剂型而言，它们在可靠的医学判断的范围之内，适用于与人类和动物的组织接触使用，而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症，与合理的利益/风险比相称。
术语“药学上可接受的盐”包括碱根离子与自由酸形成的盐或酸根离子与自由碱形成的盐，例如包括盐酸盐、氢溴酸盐、硝酸盐、硫酸盐、磷酸盐、甲酸盐、乙酸盐、三氟乙酸盐、富马酸盐、草酸盐、马来酸盐、柠檬酸盐、琥珀酸盐、甲磺酸盐、苯磺酸盐或对甲基苯磺酸盐，优选盐酸盐、氢溴酸盐、硫酸盐、甲酸盐、乙酸盐、三氟乙酸盐、富马酸盐、马来酸盐、甲磺酸盐、对甲基苯磺酸盐、钠盐、钾盐、铵盐、氨基酸盐等。本申请中，当形成药学上可接受的盐时，所述自由酸与碱根离子的摩尔量之比为约1:0.5～1:5，优选1:0.5、1:1、1:2、1:3、1:4、1:5、1:6、1:7或1:8。
在本文中，术语“受试者”或“患者”可互换使用。在一些实施方案中，术语“受试者”或“患者”是哺乳动物。在部分实施方案中，所述受试者或患者是小鼠。在部分实施方案中，所述受试者或患者是人。
术语“约”应理解为包括在平均值的三个标准偏差内或特定领域中的标准公差范围内。在某些实施方式中，约应理解为不超过0.5的变异。“约”修饰其后所有列举的值。例如，“约1、2、3”表示“约1”、“约2”、“约3”。
如本文所用，“联用”或“联合使用”意指两种或更多种活性物质可以各自作为单一制剂同时地、或各自作为单一制剂以任何顺序依次地施用于受试者。
术语“单剂量”是指含有一定量药品的最小包装单元，例如一盒药有七粒胶囊，则每个胶囊为单剂量；或者每瓶注射液为单剂量。在本文中，术语“单剂量”和“单位剂量”具有相同的含义，并可互换使用。
术语“多剂量”由多个单剂量组成。
术语“药物组合物”是指一种或多种本申请的活性成分或其药物组合与药学上可接受的辅料组成的混合物。药物组合物的目的是有利于对受试者给予本申请的化合物或其药物组合。
在本文中，除非另有说明，否则术语“包含、包括和含有(comprise、comprises和comprising)”或等同物为开放式表述，意味着除所列出的要素、组分和步骤外，还可涵盖其它未指明的要素、组分和步骤。
为了描述和公开的目的，以引用的方式将所有的专利、专利申请和其它已确定的出版物在此明确地并入本文。这些出版物仅因为它们的公开早于本申请的申请日而提供。所有关于这些文件的日期的声明或这些文件的内容的表述是基于申请者可得的信息，并且不构成任何关于这些文件的日期或这些文件的内容的正确性的承认。而且，在任何国家，在本中对这些出版物的任何引用并不构成关于该出版物成为本领域的公知常识的一部分的认可。
