Abstract
一种CTLA‑4小分子降解剂及其应用,所述CTLA‑4小分子降解剂具备式Ⅰ结构的化合物或其药学上可接受的盐、酯、氘代物、异构体、溶剂化物、前药或同位素标记物:
Description
本发明属于医药化学领域,具体地涉及一类通过抑制LRBA蛋白和CTLA-4蛋白相互作用从而导致CTLA-4蛋白降解的小分子降解剂、其制备方法、药物组合物以及在医药方面的用途。
PD-1/PD-L1抑制剂是目前最重要的肿瘤免疫类药物之一,但是临床反应率比较低(10-30%),对于大部分肿瘤患者无效,临床需新的解决方案。PD-1/PD-L1抑制剂与其它肿瘤治疗药物进行联合给药,可能是较好策略。
CTLA-4(细胞毒性T淋巴细胞相关蛋白-4)是一种蛋白受体,其作为免疫检查点起作用并下调免疫应答。它在T细胞,尤其调节性T细胞中组成型高表达,当与抗原呈递细胞表面上的CD80或CD86结合时,起到“关闭”开关的作用。CTLA-4抑制剂可以激活抗肿瘤免疫反应,用于肿瘤的免疫治疗。CTLA-4抑制剂伊匹木单抗(Yervoy,“Y”药)已经用于黑色素瘤等多种肿瘤的治疗。
考虑到CTLA-4和PD-1/PD-L1于肿瘤免疫反应不同阶段协同调控免疫反应:CTLA-4,肿瘤免疫反应早中期阶段;PD-1,肿瘤免疫反应后期阶段。所以CTLA-4与PD-1/PD-L1抑制剂联合给药是可行的,并且此联合给药策略已在临床中获得充分验证:如FDA已经批准了肝细胞癌、非小细胞肺癌等6个临床适应症。如伊匹木单抗(Yervoy,“Y”药)与PD-1抑制剂纳武单抗(OPDIVO,“O”药)联合给药时客观缓解率(ORR)与“O”药单药相比,得到显著提高。Y药与O药的双免疫治疗组合,是首个也是目前唯一获得FDA批准的双免疫疗法。
但目前的CTLA-4抑制剂如“Y”药等是抗体药物,该抗体及该类抗体药物存在一些固有局限性:1)副作用大,临床上54%左右联用患者会产生3-4级免疫治疗相关的严重副作用(irAEs),极大限制了此类药物的临床使用,同时该副作用作用与抗体的ADCC作用和免疫原性有关;2)瘤内扩散难:CTLA-4抗体药物作为大分子药物,实体瘤内浸润比较困难,限制了单用或者联合用药的治疗效果;3)依从性差:CTLA-4 抗体药物的给药方式以静脉、皮下或者肌肉注射给药为主,无法口服给药,患者依从性差。
与CTLA-4单抗类药物而言,CTLA-4小分子降解剂具有其独特优势:1)显著减少毒副作用:CTLA-4小分子降解剂通过降解CTLA-4蛋白达到解除免疫抑制的目的,本身对T细胞其它活性没有影响,并且小分子没有抗体的ADCC作用和免疫原性,因此副作用会大大降低;2)瘤内易扩散:小分子药物较容易浸润到实体瘤内,大大提高单用或者联合用药的治疗效果;3)依从性好:小分子药物可以口服用药;4)价格优势:小分子药物生产成本低。
但是目前在全球范围内,尚未有CTLA-4小分子降解剂或小分子抑制剂的开发或报道。

药物组合物和剂量
本发明还提供药用组合物,其包含治疗有效量的与一种或多种药用载体(添加剂)和/或稀释剂一起配制的一种或多种式(I)化合物,和任选的一种或多种上述其它治疗剂。可通过任意合适方式给予本发明化合物以用于任意上述用途,例如口服,诸如片剂、胶囊剂(各包括持续释放或定时释放制剂)、丸剂、粉剂、颗粒剂、酏剂、酊剂、悬浮液(包括纳米悬浮液、微悬浮液、喷雾干燥的分散液)、糖浆和乳液;经舌下;含服;经肠胃外,诸如通过皮下、静脉内、肌内或胸骨内注射或输注技术(例如以无菌可注射水性或非水性溶液或悬浮液形式);经鼻,包括向鼻膜给药,诸如通过吸入喷雾;局部,诸如以乳膏剂或软膏剂形式;或经直肠,诸如以栓剂形式。它们可单独给药,但通常使用基于所选给药途径和标准药学实践选择的药物载体给药。
根据本领域技术人员认识范围内的诸多因素来调配药用载体。这些因素包括,但不限于:所调配活性剂的类型和性质;含有活性剂的组合物所要给药的受试者;组合物的预期给药途径;及所靶向的治疗适应症。药用载体包括水性和非水性液体介质及各种固体和半固体剂型。
上述载体可包括除活性剂外的诸多不同成分和添加剂,上述其它成分出于本领域技术人员公知的各种原因包括于制剂中,例如稳定活性剂、粘合剂等。关于合适的药用载体和载体选择中所涉及的因素的描述可参见多个容易获得的来源,例如Allen,L.V.Jr.et.al.Remington:The Science and Practice of Pharmacy(2 Volumes),22nd Edition(2012),Pharmaceutical Press。
当然,本发明化合物的剂量方案取决于已知因素而有所变化,诸如具体药剂的药效学特性及其给药模式和途径;接受者的物种、年龄、性别、健康状况、医学病状和重量;症状的性质和程度;同时治疗的种类;治疗频率;给药途径、患者的肾和肝功能及期望效应。根据一般指导,当用于指定效应时,各活性成 分的日口服剂量应为约0.001mg/天至约10-5000mg/天,优选地为约0.01mg/天至约1000mg/天,且最优选地为约0.1mg/天至约600mg/天。在恒速输注期间,静脉内最优选剂量应为约0.01mg/kg/分钟至约10mg/kg/分钟。本发明化合物可以单一日剂量给药,或可以每日两次、三次或四次的分开剂量给药总日剂量。
所述化合物通常以与根据预期给药形式(例如口服片剂、胶囊剂、酏剂和糖浆剂)适当地选择且与常规药学实践相符合的合适药物稀释剂、赋形剂或载体(在本文中统称为药物载体)的混合物形式进行给药。
适于给药的剂型(药物组合物)可含有约0.1毫克至约2000毫克活性成分/剂量单位。在这些医药组合物中,以组合物的总重量计,活性成分通常将以约0.1-95重量%的量存在。
典型的可注射制剂可如下制备:以无菌方式将至少一种本发明化合物(250mg)置于瓶中、以无菌方式冻干并密封。为进行使用,将瓶内容物与2mL生理盐水混合,以产生可注射制剂。
本发明范围包括(单独或与药物载体组合)包含治疗有效量的至少一种本发明化合物作为活性成分的药物组合物。任选地,本发明化合物可单独使用、与本发明其它化合物组合使用或与一种或多种其它治疗剂(例如抗癌剂或其它药学活性物质)组合使用。
不考虑所选择的给药路径,通过本领域技术人员已知的常规方法来将本发明的化合物(其可以合适的水合形式使用)和/或本发明的药物组合物配制成药用剂量形式。
可改变活性成分在本发明的药物组合物中的实际剂量水平,从而获得对于实现特定患者的期望的治疗响应、组成和给药模式有效的而对患者无毒的活性成分量。
选定的剂量水平会取决于多种因素,包括所用的本发明的特定化合物或其酯、盐或酰胺的活性;给药路径;给药时间;所用的特定化合物的排泄速率;吸收速率和程度;治疗的持续时间;与所用的特定化合物组合使用的其它药物、化合物和/或物质;所治疗的患者的年龄、性别、重量、状况、一般健康和先前的医学史等医学领域公知的因素。
具有本领域普通技术的医生或兽医可容易地确定并开出有效量的所需药物组合物。例如,为了达到所期望的治疗效果,医师或兽医可在低于所需的水平开始药物组合物中所用的本发明化合物的较量,并逐步增加剂量直至实现所期望的效果。通常,合适日剂量的本发明化合物将是有效产生治疗效果的最低剂量的化合物的量。此种有效剂量通常取决于上述因素。通常,口服、静脉内、肌肉注射、脑室内和皮下剂量的用于患者的本发明化合物的范围为约0.01至约1000mg/kg体重/天。如果需要的话,有效日剂量的活性化合物可以两个、三个、四个、五个、六个或更多个亚剂量在一天当中的适当的间隔分别给药,任选地呈单位剂型形式。在本发明的某些方面中,服药为每天一次给药。
虽然本发明化合物可单独给药,但优选以药物制剂(组合物)形式给予化合物。
本发明提到的上述特征,或实施例提到的特征可以任意组合。本案说明书所揭示的所有特征可与任何组合物形式并用,说明书中所揭示的各个特征,可以任何可提供相同、均等或相似目的的替代性特征取代。因此除有特别说明,所揭示的特征仅为均等或相似特征的一般性例子。

3.肿瘤接种:0.02mL(0.2×10
6个)MC-38细胞皮下接种于每只小鼠的右后背。接种后第7天,测量动物肿瘤体积,然后根据肿瘤体积大小随机化分组并开始给药。
4.实验指标:实验指标是考察肿瘤生长是否被抑制、延缓或治愈。每周两到三次用游标卡尺测量肿瘤直径。肿瘤体积的计算公式为:V=0.5a×b
2,a和b分别表示肿瘤的长径和短径。化合物的抑瘤疗效用TGI(%)。TGI(%),反映肿瘤生长抑制率。TGI(%)的计算:TGI(%)=[(1-(某处理组给药结束时平均瘤体积-该处理组开始给药时平均瘤体积))/(溶剂对照组治疗结束时平均瘤体积-溶剂对照组开始治疗时平均瘤体积)]×100%。
