Abstract
本发明涉及含有索拉非尼或其药学上可接受的盐或其多晶型物、水合物或溶剂合物的局部眼用药用组合物及其制备方法和其用于治疗眼科病症的用途。
Description
本发明涉及含有索拉非尼或其药学上可接受的盐、或其多晶型物、水合物或溶剂合物的局部眼用药用组合物及其制备方法和其用于治疗眼科病症的用途。
索拉非尼,即4{4-[3-(4-氯-3-三氟甲基苯基)-脲基]-苯氧基}-吡啶-2-甲酸甲基酰胺,式(I)化合物:
为有效的抗癌和抗血管发生的药剂(WO 00/042012),其具有包括对VEGFR、PDGFR、raf、p38和/或flt-3激酶信号分子的抑制活性的各种活性(WO 2004/113274、WO 2005/000284)且其可用于治疗各种疾病和病状,如过度增殖病症,诸如癌症。此外,索拉非尼的甲苯磺酸盐及其稳定的多晶型物(多晶型物I)公开在WO 2006/034797中。
年龄相关性黄斑变性(AMD)是老年人口致盲的主要原因且被公认为干AMD和湿AMD (Expert Opin. Ther. Patents (2010), 20 (1), 103-11)。该干或非渗出性形式包括视网膜色素上皮组织(RPE)的萎缩变化和肥大变化。该干形式以黄斑脉络膜小疣为特点,这些黄斑脉络膜小疣为含有死细胞和代谢产物的着色区域,其使视网膜变形且最后导致急性视力损失。具有非渗出性AMD(干形式)的患者可进展成湿或渗出性或新血管形成AMD,其中病理学脉络膜新生血管膜(CNVM)在视网膜下发展,渗漏液体和血液,且如果保持不治疗,最终在相对较短的时间范围内导致中心致盲盘状疤痕(centrally blinding disciform scar)。脉络膜新血管形成(CNV),新血管自脉络膜毛细网络穿过Bruch膜/RPE界面生长到神经视网膜,导致视网膜剥离、视网膜下和视网膜内水肿及疤痕形成。
除了经由血液之外通向在巩膜与视网膜之间的脉络膜是困难的。眼睛由三个主要的解剖学上隔室:前房、后房和玻璃体腔构成,它们彼此具有有限的生理学相互作用。视网膜位于玻璃体腔的后部,且受巩膜保护不受外部影响,所述巩膜是眼睛的白色韧性的不渗透性壁。脉络膜血液流动是运载物质到脉络膜的常用方法且需要例如口腔或静脉内施用药物。大多数药物不能通过滴眼液或在眼睛附近的储存物(depot)传送到脉络膜。一些药物已经通过注射到眼睛的玻璃体腔而传送到视网膜且因此传送到脉络膜。
VEGF(血管内皮生长因子)是正常血管发育以及在肿瘤及经历异常血管发生的其他组织中的血管发育中的关键细胞因子且似乎在CNV形成的发病机制中起着重要作用(Expert Opin. Ther. Patents (2010), 20(1), 103-118;Expert Opin. Ther. Patents (2009), 18(10), 1573-1580;J. Clin. Invest. (2010), 120(9), 3033-3041;J. Cell. Physiol. (2008), 216, 29-37;New Engl. J. Med. 2006, 355, 1474-1485;WO 2010/127029;WO 2007/064752)。描述了阻断VEGF的作用的药物来治疗湿AMD,诸如适配子,如哌加他尼(pegaptanib) (New Engl. J. Med. 2004, 351, 2805-2816);或VEGF抗体,如兰尼单抗(ranibizumab)(New Engl. J. Med. 2006, 355, 1419-1431)或贝伐单抗(bevacizumab)(Ophthalmology, 2006, 113, 363-372)。然而,所述药物必须通过玻璃体内注射到眼睛中来施用。描述了也是VEGF抑制剂的索拉非尼通过口服来治疗CNV (Clinical and Experimental Ophthalmology, 2010, 38, 718-726)。描述了也是VEGF抑制剂的帕唑帕尼(Pazopanib)通过局部施用含有帕唑帕尼水溶液的滴眼液来治疗AMD (WO 2011/009016)。WO 2006/133411描述通过局部施用脂质体制剂治疗CNV的化合物。WO 2007/076358、US2006257487描述用于局部施用的水性眼用制剂。WO 2008/27341描述用于局部施用到眼睛的乳液。Young-Hoon P.等(Clinical and Experimental Ophthalmology, 2010, 38, 718-726)描述了索拉非尼通过口服对CNV的作用。
尽管描述了在本领域中的进展,但是仍然需要用于治疗眼科病症如AMD的改善的药物。特定地,还需要可容易地施用且因此将增加患者的顺应性的局部眼用药用组合物如滴眼液。该局部眼用药用组合物必须在眼睛中提供对于有效疗法足够的活性剂的浓度。这取决于活性剂的溶解度和释放性能。在液体制剂的情况下,活性剂的溶解性质和化学稳定性是重要的。为了支持高顺应性,该局部眼用药用组合物不应该必须每天使用多于5次,次数越少越好。赋形剂的类型和量以及制备药用组合物的方法对于活性剂在眼睛中、特别是在眼睛后部(例如,在视网膜、Bruch膜和脉络膜的区域中)的释放性质、生物利用度、局部眼用药用组合物的制造方法的稳定性和工业实用性是重要的。
本发明要解决的问题在于提供包含作为活性剂的索拉非尼的局部眼用药用组合物,其具有足够的稳定性且其通过避免静脉内施用或口服或注射到眼睛中或眼睛附近(例如,玻璃体内或其他注射)而在眼睛中、特别是在眼睛后部实现有效浓度的索拉非尼以便治疗眼科病症。
根据本发明的药用组合物通过局部施用令人惊讶地提供有效治疗眼科病症的足够量的活性剂到眼睛中。特定地,根据本发明的药用组合物提供足够量的所述活性剂到眼睛后部,即,根据本发明的药用组合物实现所述活性剂从眼睛前部到眼睛后部的输送。另外,根据本发明的药用组合物具有足够的稳定性,而所述活性剂没有任何有意义的降解。

药学上可接受的载体或赋形剂为在符合活性剂的有效活性的浓度下对患者相对无毒且无害以使得可归因于所述载体或赋形剂的任何副作用不会损害所述活性剂的有益作用的任何载体或赋形剂。

除非另有说明,否则重量数据为重量百分数且份数为重量份。
实施例:
实施例1:在油酰基聚乙二醇甘油酯中包含索拉非尼甲苯磺酸盐的眼用悬浮液(20mg/ml)
将200mg微粉化索拉非尼甲苯磺酸盐混合到油酰基聚乙二醇甘油酯(10ml)中。该混合物通过在室温下搅拌15分钟而匀化。
实施例2:在液体石蜡中包含索拉非尼甲苯磺酸盐的眼用悬浮液(20mg/ml)
将400mg微粉化索拉非尼甲苯磺酸盐混合在20ml轻质液体石蜡中,该混合物通过在室温下搅拌15分钟而匀化。
实施例3:在基于水的载体中包含索拉非尼的眼用组合物(20mg/ml)
在70℃下将1.7g羟丙基甲基纤维素15cp (HPMC)分散在等渗氯化钠溶液(48g,0.9% NaCl,在水中)中。在搅拌的同时将该混合物冷却到室温。在室温下蒸发水,且接着加入聚山梨酸酯80 (0.5g)并将其在适度搅拌下溶解。将518mg索拉非尼甲苯磺酸盐加到所制备的载体的等分试样(24.5g)中且悬浮液通过在室温下轻缓搅拌15分钟而匀化。
实施例4:含有索拉非尼的组合物在激光诱发的脉络膜新血管形成(CNV)模型中的局部功效
本研究的目的在于确定每日两次局部施用(滴眼液)根据本发明的局部眼用药用组合物在激光诱发的脉络膜新血管形成的大鼠模型中是否导致血管渗漏和/或脉络膜新血管形成减少(Dobi等,Arch. Ophthalmol. 1989, 107(2), 264-269或Frank等,Curr. Eye Res. 1989 Mar, 8(3), 239-247)。
为此目的,选择没有可见眼科缺陷体征的着色的棕色挪威大鼠。在第0天,通过腹膜内注射(15mg/kg甲苯噻嗪和80mg/kg氯胺酮(ketamine)(溶解于含有5mg/ml氯丁醇半水合物和丙二醇的水中))麻醉动物。在滴注一滴0.5%阿托品(atropin)(溶解于含有苯扎氯铵的0.9%盐水中)以扩瞳后,通过使用532nm氩激光器在每个动物的一个眼的视网膜中灼烧6个孔(破坏Bruch膜)(病灶尺寸:50μm,激光强度:150;刺激持续时间:100 ms)来诱发脉络膜新血管形成。对于各种试验制剂(含有根据本发明的实例的制剂和没有活性剂的载体制剂),在23天的全面观察期期间以10:14小时间隔每日两次对患眼施用10μl。在开始研究之前和在研究期间每日一次记录所有动物的体重。在第21天使用荧光基底照相机(Kowe Genesis Df, Japan)进行血管造影。此时,在麻醉并扩瞳之后,皮下注射10%钠荧光素(染料,溶于水中)且在染料注射之后的2分钟和10分钟记录图片。在血管造影照片上荧光素的血管渗漏通过对于群分配盲的三个不同的检查者评价(实例对相应载体)。各病灶用0(不渗漏)至3(强烈染色)评分,且将所有六处病灶的平均值用作各动物的值。在第23天,处死动物且收集眼睛并在室温下将其固定在4%低聚甲醛溶液中历时1小时。在洗涤之后,小心地剥离视网膜,且洗涤巩膜-脉络膜复合体,将其断块(blocked)并用FITC-isolectine B4抗体染色以显现脉管系统。随后,将巩膜-脉络膜平坦地安装并在荧光显微镜(Keyence Biozero)下在488nm激发波长下检验。使用ImageTool软件测量脉络膜新血管形成的面积(μm2)。
