Description

含有西罗莫司酯化物的药物组合物及其制备方法
技术领域
本发明属于药物制剂领域, 具体涉及含西罗莫司酯化物的药物组合物及其 制备方法。 背景技术
西罗莫司酯化物(英文名, Temsirolimus )是雷帕霉素的 42-双 -羟甲基丙酸 酯, 其结构式如下: -
Figure imgf000002_0001
该化合物首次在美国专利 US5362718A中公开,其在体内和体外模型中表现出对 细胞生长繁殖的抑制性, 而非细胞毒性, 它还可以延迟肿瘤的发展时间或肿瘤的 复发时间。 作用机理被认为同西罗莫司的作用机理类似, 主要通过与胞质蛋白 FKBP 结合并形成复合体, 抑制酶 mTOR (雷帕霉素的哺乳动物靶, 也称为 FKBP12-西罗莫司相关蛋白 [FRAP] )。 mTOR激酶活性的抑制使得多个信号传导 路径得到抑制, 包括细胞因子剌激的细胞增殖, mRNA对多种关键蛋白的翻译, 这些蛋白调节细胞周期的 G1相, 和 IL-2-诱导转录, 由此抑制细胞周期从 G1到 S的过程, 这种抑制 G1到 S相的西罗莫司酯化物作用机理对抗癌药物是一种新 的机理。
研究表明西罗莫司酯化物对多种组织各异性肿瘤细胞的生长都有抑制作 用, 如中枢神经系统癌、 白血病、 乳腺癌、 前列腺癌、 黑色素瘤等对西罗莫司酯 化物最为敏感, 这归功于其具有在细胞周期的 G1相中能够捕集细胞的能力。 针对西罗莫司酯化物的优势, 美国 FDA于 2007年 5月批准惠氏公司研制 的两瓶装制剂西罗莫司酯化物浓缩液和稀释剂 ( TORISEL® )上市, 用于晚期肾 细胞癌,欧盟批准该制剂用于至少具有三个以上预后危险因子的晚期肾细胞癌的 一线治疗。
由于西罗莫司酯化物的水溶性很差, 而且为非电解质, 原料药本身不稳定, 需要在 -20°C以下进行存储, 因此惠氏公司开发的 TORISEL® 制剂为两瓶装, 一 瓶为非水溶剂的浓缩液,另一瓶为特配的稀释剂,含有乙醇、丙二醇等非水溶媒。 但该药物在有机溶媒中观察到化学不稳定性, 导致异构体和氧化降解杂质的增 长, 而且临床使用前需要先将稀释剂注入到浓缩液中, 混勾后再配伍生理盐水进 行滴注, 这样就造成临床使用不方便和二次污染的风险。 同时在非肠道注射给药 时因 TORISEL®处方采用大量的乙醇、 丙二醇等非水复合溶媒, 导致刺激性或 毒性增加, 临床应用时会引起超过敏反应, 血管萎缩等严重副作用。
惠氏公司拥有的中国专利申请 CN1829514A也公开了西罗莫司酯化物的冻 干制剂, 但该冻干制剂中并未加入助溶剂, 因此该冻干制剂仍然为两瓶装制剂, 需要配一瓶含两亲性化合物的稀释剂一起使用。在产品使用时,将专用的含两亲 性化合物的稀释剂与冻干制剂预先混合后再使用。 配伍过程复杂、容易造成二次 污染。 而且这种两瓶装形式的制剂无形中增加了制剂本身的成本。 此外, 稀释剂 中加入的聚山梨醇酯类化合物经注射后会 ]起溶血等副作用。 发明内容
为解决以上问题, 在研究实验过程中, 本发明的研究人员发现, 虽然西罗莫 司酯化物的水溶性很差,但是在制剂处方中可以加入助溶剂来提高西罗莫司酯化 物的溶解度。 经过研究人员潜心研究, 对大量助溶剂如聚山梨醇酯 20、 60、 80, 聚氧乙烯蓖麻油 (Cremoophor EL ), 聚乙二醇硬脂酸酯 15 ( Solutol-HS15 ), 生 育酚聚乙二醇琥珀酸酯(TPGS ), 泊洛沙姆 F68, 胆酸钠, 脱氧胆酸钠, 磷脂等 筛选, 最终发现使用助溶剂聚乙二醇硬脂酸酯 15 ( Solutol-HS15 )不但可以提高 西罗莫司酯化物的溶解度, 而且不影响其稳定性。 因此选用常温下为蜡状的助溶 剂聚乙二醇硬脂酸酯 15 ( Solutol-HS 15 )加入到冻干处方中, 制备得到一瓶装的 西罗莫司酯化物冻千药物组合物。 该组合物可以解决浓缩液 TORISEL®和 CN1829514A中公开的两瓶装冻干制剂的配伍复杂性和易造成二次污染风险、成 本高等问题, 实现西罗莫司酯化物的一瓶装制剂产品。
具体地, 本发明提供了一种冻千形式的稳定的药物组合物,其含有西罗莫司 酯化物和聚乙二醇硬脂酸酯 15 ( SolutoI-HS15 )。
其中, 西罗莫司酯化物与聚乙二醇硬脂酸酯 15的含量比为 1:10~50 ( w/w ), 优选 1:20~40 ( w/w ), 更优选 1:30 ( w/w )。
本发明的西罗莫司酯化物药物组合物进一步含有冻千赋形剂。其中, 所述冻 干赋形剂可选自海藻糖、 棉籽糖、 葡萄糖, 或其中任意两种或三种的混合物, 优 选海藻糖。西罗莫司酯化物与冻干赋形剂的含量比为 1:1〜100( w/w ),优选 1 :5~40 ( w/w )。 冻干赋形剂的加入, 有利于提高产品的稳定性。
本发明的西罗莫司酯化物药物组合物可进一步含有稳定剂。其中, 所述稳定 剂包括但不限于柠檬酸、 乙酸、 EDTA、 氨基酸, 或其中任意两种或两种以上的 混合物, 优选柠檬酸, 更优选柠檬酸和 EDTA的混合物。 西罗莫司酯化物与稳定 剂的含量比为 1 :0.01 0.24 ( w/w:)。 这些稳定剂可以使西罗莫司酯化物的药物组 合物的稳定性得到提高, 同时可降低西罗莫司酯化物异构体的含量。
本发明的西罗莫司酯化物药物组合物可进一步含有抗氧化剂。其中, 所述抗 氧化剂包括但不限于柠檬酸、 α-生育酚、 BHA、 BHT、 EDTA, 氨基酸, 或其中 任意两种或两种以上的混合物, 优选 α-生育酚, 更优选 α-生育酚和 EDTA的混 合物。其中所述氨基酸可为任何具有抗氧化作用的氨基酸, 例如但不限于曱硫氨 酸、 半胱氨酸, 也可以是小分子肽, 例如但不限于谷胱甘肽。 西罗莫司酯化物与 抗氧化剂的含量比为 1 :0.01~0.72 ( w/w:)。 由于西罗莫司酯化物易被氧化, 加入 一定量的抗氧化剂,将使得西罗莫司酯化物的稳定性得到进一步提高。特别是当 西罗莫司酯化物原料药中含有乙瞇等有机溶剂残留时,抗氧化剂的加入能显著降 低冻干制剂中有关物质的含量。
此外, 本发明还提供一种含有西罗莫司酯化物的药物组合物的制备方法, 步 骤如下:
1 )油相的制备: 将西罗莫司酯化物溶于过程溶剂, 并加入稳定剂和 /或抗氧 化剂;
2 )水相的制备: 将冻干赋形剂、 聚乙二醇硬脂酸酯 15溶于注射用水中, 作 为水相;
3 )西罗莫司酯化物药物组合物的制备: 将步骤 1 )的油相和步骤 2 )的水相 混匀, 分装, 冻干即得。
其中, 步骤 1 )所述过程溶剂选自乙醇、叔丁醇、 聚乙二醇、二甲基甲酰胺, 或其中任意两种或两种以上混合物。 优选叔丁醇, 因为它的凝固点为 25°C , 可 以被冷凝器捕集, 不伤害冻干机。 同时这些过程溶剂可以大大缩短配料时间, 增 加中间体溶液的稳定性和化学稳定性, 为产品制造的质量安全提供保证。过程溶 剂的浓度优选为 10~100% ( w/w )。 . 本发明的西罗莫司酯化物的药物組合物在临床上可作为免疫抑制剂, 抗炎 剂, 抗真菌剂, 抗增生和抗肿瘤剂, 使用时可采用注射用水复溶后直接注射给药 或通过与生理盐水、 葡糖糖溶液配伍后静脉滴注给药。 因此, 本发明还提供所述 的药物組合物在制备用于预防和 /或治疗免疫性疾病、 炎症、 真菌感染、 增生性 疾病和肿瘤的药物中的应用; 以及所述的药物组合物用于预防和 /或治疗免疫性 疾病、 炎症、 真菌感染、 增生性疾病和肿瘤的用途。
聚乙二醇硬脂酸酯 15 ( Solutol-HS15 )是由巴斯夫公司开发的一种高效增 溶剂, 现已被英国、 德国、 欧洲等药典收录。 在美国、 加拿大上市的维生素 K 注射液就使用 Solutol-HS15作为增溶剂。 它的安全性已被证实, 并得到认可。 其 毒性较目前注射剂常用的助溶剂聚山梨醇酯 80还低, 1%的低浓度以下基本没有 溶血现象发生, 其溶血发生率是聚山梨醇酯 80的十分之一。 且聚乙二醇硬脂酸 酯 15 ( Solutol-HS15 )极易溶于水, 与助溶剂聚山梨醇酯 80不同的是在室温下 Solutol-HS15为蜡状固体, 熔点为 30°C , 能够满足冻干制剂辅料所需要的特性要 求。 但目前还未有上市冻干产品使用到该助溶剂作为辅料。 鉴于该助溶剂 Solutol-HS15的各种优势以及其可作为冻干制剂辅料等性质, 本发明通过一些实 验对助溶剂进行筛选研究 , 最终获得了助溶剂 Solutol-HS 15与西罗莫司酯化物、 以及相应冻千赋形剂、 稳定剂、 抗氧化剂和过程溶剂制备成的冻干药物组合物, 该组合物可直接加注射用水或生理盐水复溶配伍使用,实现西罗莫司酯化物的一 瓶装制剂产品。 同时, 该组合物还提高了西罗莫司酯化物的产品稳定性, 进一步 降低了西罗莫司酯化物的异构体含量及氧化降解杂质。同时解决了 TORISEL®处 方的乙醇、 丙二醇等非水复合溶媒导致其刺激性或毒性增加, 临床应用时所引起 的超过敏反应, 血管萎缩等严重副作用等问题, 以及 CN1829514A 专利公开的 冻干制剂的两瓶装制剂配伍复杂性和易造成二次污染风险、成本高等问题。 同时 本发明的药物组合物制备工艺简单、 临床使用方便, 生产成本低, 保证了产品使 用的有效性、 安全性和稳定性。
本发明的西罗莫司酯化物的冻干药物組合物具有如下优势:
1 ) 冻干药物组合物复溶时无需使用到乙醇和丙二醇等非水溶媒,有效解 决了这些非水溶媒引起的刺激性, 毒性, 超过敏反应, 血管萎缩等严 重副作用;
2 ) 提高了药物组合物的稳定性, 尤其在异构体含量以及氧化降解杂质的 控制上优于 TORISEL®浓缩液制剂;
3 ) 直接将助溶剂聚乙二醇硬脂酸酯 15 ( Solutol-HS15 )加入到处方中, 制备得到的西罗莫司酯化物冻干药物组合物可直接用注射用水或生 理盐水复溶配制使用, 操作筒单, 工艺安全, 降低了生产成本, 适合 工业化生产。 具体实施方式
以下通过实施例来进一步说明本发明。 必须说明, 本发明的实施例是用于 说明本发明, 而不应理解为对本发明的限制。 实施例 1 助溶剂的筛选
由于西罗莫司酯化物的水溶性很差, 需要助溶剂来增溶, 本发明人釆用助 溶剂聚山梨醇酯 80, 聚乙二醇硬脂酸酯 15 ( SoIutol-HS15 ), 生育酚聚乙二醇琥 珀酸酯(TPGS ), 脱氧胆酸钠等进行了筛选研究, 设计配方如下表 1:

注: Siroc A为西罗莫司酯化物异构体 A; T-Siroc C为: 西罗莫司酯化物异构体 C。
异构体 A和 C以及其他杂质采用 HPLC ( Agilent 1200 )进行检测分析, 其 中色谱柱为 XDB- C18 ( Agilent, 4.6mm (ID)x l5 cm, 5 μηι ), 在波长 280nm、 柱温 50°C、 流速 1.5ml /min、 进样量 20μ1的条件下, 用乙腈作为稀释剂, 进行梯度洗 脱(流动相 Α为 0.01M磷酸二氢钟緩冲液: 乙腈 =50:50; 流动相 B为 0.01M磷 酸二氢钾緩冲液: 乙腈 =20:80 )。
实验结果显示, 在四种典型的助溶剂聚山梨醇酯 80、 聚乙二醇硬脂酸酯 15 ( Solutol-HS15 ) 生育酚聚乙二醇琥珀酸酯 (TPGS )和脱氧胆酸钠中, 含聚乙 二醇硬脂酸酯 15 ( Solutol_HS15 )的西罗莫司酯化物的药物组合物的稳定性最佳, 因此在对后续研究中, 以聚乙二醇硬脂酸酯 15 ( SoIutol-HS15 )作为助溶剂进行 研究。 实施例 2 配制 TORISEL®浓缩液
