本申请涉及药物组合物技术领域,具体涉及一种稳定的高浓度自缓冲药物组合物。
背景技术
血管内皮生长因子(VEGF)是血管生成和新生血管形成的已知调节剂,并且已被证明是与肿瘤和眼部疾病或障碍形成的关键因子。包括VEGF受体融合蛋白或VEGF抗体在内的许多VEGF结合分子已被批准用于人类和其他哺乳动物中的治疗性用途。例如,(Regeneron Pharmaceuticals,Inc.),其是一种抗VEGF药物,通过与VEGF紧密结合,降低血管通透性,进一步抑制新生血管的生成。美国食品药品监督管理局(Food and drug administration,FDA)和欧洲药物管理局(European medicines agency,EMA)从2014年8月以来相继批准了其通过玻璃体注射治疗视网膜静脉阻塞继发黄斑水肿、湿性年龄相关性黄斑变性和糖尿病性黄斑水肿等适应症。
但是,现有技术还存在着许多不足和需要改进的地方。例如,药物配制品中治疗性抗体的浓度根据施用途径等方式的不同存在广泛地变化。当受注射体积限制时,通常需要开发高浓度的抗体配制品。例如,对于玻璃体内注射或皮下给药经常需要开发高浓度的配制品。同时,蛋白质药物的配制本身就可能给制药科学家带来许多挑战。因此,必须找到一种稳定蛋白质药物并使其对由蛋白水解,变性等导致的降解、聚集、错误折叠等具有抗性的制剂。特别是对于在实质性方面与已知蛋白质不同的工程化蛋白质,找到合适的稳定性条件可能具有挑战性。还令人希望的是具有对患者方便的形式的蛋白质药物。所希望的特性包括环境温度和冷藏温度下的稳定性、长期储存的适用性、合适的给药时间和给药剂量,以及最小化给予后的不适。
虽然现有技术中已经发现了适合于玻璃体内施用的制剂,但是目前仍需要稳定的适合眼科给药的高浓度VEGF受体融合蛋白的液体制剂。含有高浓度VEGF受体融合蛋白的制剂可以减少给药体积,缩短眼部注射时间,增加给药剂量,延长给药间隔,降低给药频率,并提高制造和储存效率。同时,研究还发现很多常用的用于配制药物蛋白的缓冲剂,尤其对于眼科用药,具有一定的限制和风险,有可能影响药物的安全性。
缓冲剂,例如:乙酸盐、琥珀酸盐、柠檬酸盐、组氨酸(咪唑)、磷酸盐和Tris,其已经被发现在用于配制药物蛋白时具有不希望的限制和缺点,具体而言,制剂中额外的组分,其使配制过程变得复杂,增加了有害组分、影响药物整体稳定性、贮存期限,同时增加最终用户可接受性的风险。本领域普遍知晓现有技术中虽存在无缓冲盐的体系,但针对具体药物获得有效的无缓冲盐体系的药物组合物是一项挑战性的工作,结果往往是难以预料,高浓度自缓冲体系的技术难度则更高,同时,在工业上,药物组合物稳定性的提高是很有挑战的,从制剂角度上,高蛋白浓度导致更高的蛋白聚集率,因为不同的组成成分更近距离的接触会导致分子间的吸引和自我聚集事件的发生。由于体积排阻和道南平衡效应,获得符合UF/DF步骤要求的pH和辅料浓度也是一项挑战,更高的蛋白浓度加剧了这种挑战,因此,有必要继续优化缓冲体系,开发稳定的适合眼科给药的高浓度VEGF受体融合蛋白的液体制剂。

本申请的目的之一是提供改善的具有高浓度的、无需额外的缓冲剂的VEGF结合分子高浓度药物组合物,即,本申请提供了一种无缓冲盐的体系,高浓度的蛋白自缓冲药物组合物,发明人通过多年的探索和试验,最终制备获得了一种VEGF结合分子的高浓度自缓冲水性药物组合物。此外,本申请还令人惊讶的发现高浓度自缓冲体系药物组合物还具有很高的稳定性,应用前景广阔。
本申请公开了一种自缓冲高浓度的VEGF结合分子水性药物组合物。高浓度体系本身容易发生聚集事件使得制剂不稳定,而自缓冲高浓度体系更是如此,一般而言,自缓冲高浓度体系在室温条件下难于储存,聚集事件更是极易发生。本申请公开的阿柏西普药物组合物是稳定的,且具有对于生产、储存和分配药物而言足够的贮存期限。例如,本申请公开的自缓冲高浓度阿柏西普药物组合物在室温贮存条件(例如,25℃)下具有至少1个月、3个月或6个月的储存期限。

表1.6制剂A2-A4黏度和渗透压数据
试验例A1和试验例A2为具有缓冲剂体系的方案、试验例A3和试验例A4为自缓冲体系方案。实验结果发现:在室温(25±2℃)振荡一周、冻融循环3次、2-8℃放置6个月的条件下,试验例A1、试验例A2、试验例A3样品较稳定,SEC-HPLC纯度等无明显变化。在25℃放置1个月的条件下,试验例A1、试验例A2、试验例A3、试验例A4,除nr-SDS-PAGE纯度明显下降外,其他各个纯度均无明显变化。
在40℃±2℃放置1个月的条件下,试验结果如表1.2-1.4所示,40℃±2℃下制剂A2、A3的SEC主峰纯度变换趋势图如图1所示,不同放置条件下制剂A2、A3的SEC聚体纯度变换趋势图如图2所示。从上述结果可知,试验例A3的SEC-HPLC纯度较试验例A2获得了较大的提升。具体而言,试验例A3与试验例A2相比,SEC-HPLC主峰纯度提高了5.9%,聚集体降低5.9%。在工业上,蛋白质稳定性的提高很困难,1-2%纯度的提高具有有很高的意义,5.9%的纯度提高是一个非常显著的突破。另外在制备工艺过程中自缓冲体系的高浓度制剂制备更加节约辅料的成本。综上,试验例A1-A4的试验结果表明,本申请的不含组氨酸和磷酸盐缓冲剂的自缓冲制剂在整个研究过程中均显示出极好的稳定性。
