Abstract
一种速效胰岛素组合物及其医药用途,该组合物包含:1)门冬胰岛素,和2)伊洛前列素和他氟前列素中的至少一种,其比现有胰岛素类似物产品的市售制剂具有更快的药代动力学,具有良好的稳定性,且对注射部位的刺激性小。
Description
本公开属于生物医药领域,涉及包含1)门冬胰岛素,和2)伊洛前列素和他氟前列素中的至少一种的药用制剂。
糖尿病(DM,Diabetes Mellitus)是一种常见的慢性非传染性疾病,是由遗传和环境因素相互作用而引起的临床综合征,是一种以血糖升高为特征的代谢性、终生性疾病。根据IDF公布的数据,2019年中国糖尿病患病人数约为1.16亿人,中国已成为全球糖尿病患病人数最多的国家;与此同时,糖尿病患者数量仍在持续快速增长。IDF预测2040年中国糖尿病患病人群数量将达到1.51亿人。我国胰岛素市场增长速度也超过了全球平均增速。
为帮助缓解/避免高血糖水平,糖尿病患者需要长期多次实施注射疗法;胰岛素按作用时间分为速效胰岛素、中效胰岛素,和长效胰岛素。对于糖尿病患者,其在进餐后由于食物吸收,导致血糖快速升高,若此时胰岛素起效太慢或释放不足,则会导致进餐后高血糖症。针对此类现象,已有作用为减少注射-起效间隔的胰岛素制剂产品,其作用机制包括通过改变人胰岛素中氨基酸链的序列进而改变胰岛素起效时间(例如赖脯胰岛素,
的原料药;门冬胰岛素,
的原料药)与改变胰岛素聚集体存在状态进而加速胰岛素起效(例如赖谷胰岛素APIDRA,缺乏Zn而降低六聚体存在)。
是目前唯一获批的新一代更快起效的餐时胰岛素注射剂,包含门冬胰岛素,增加吸收速度的维生素B3(烟酰胺),以及确保稳定性的精氨酸。即使如此,仍需一种更快的胰岛素组合物,其可在进餐时间或进餐后使用,比现有胰岛素产品更快摄取,更快起效;同时,保证长期储存的理化稳定性与注射时的安全及可耐受性。

定义
本公开的“药物组合物”表示含有本文所述门冬胰岛素与伊洛前列素和他氟前列素中的至少一种的组合与其他化学组分的混合物,所述其他化学成分为例如生理学/可药用的载体和赋形剂。药物组合物的目的是保持门冬胰岛素以及伊洛前列素和/或他氟前列素的稳定性,促进对生物体的给药,利于活性成分的吸收进而发挥生物活性。本文中,“药物组合物”和“制剂”并不互相排斥,有时可以互换使用。
组合物的“化学稳定性”用于本文指共价蛋白质结构的改变,其导致形成化学降解产物,所述产物与天然蛋白质结构相比具有潜在的更小生物学潜能和/或潜 在的增加的免疫原性性质。可形成各种化学降解产物,取决于天然蛋白质的类型和性能和蛋白质暴露的环境。在蛋白质制剂的贮存和使用过程中经常看到化学降解产物的量增加。大多数蛋白质容易脱酰胺,这是在谷氨酰基或天冬酰胺基残基中的侧链酰胺基水解形成游离羧酸或天冬酰胺基残基水解形成IsoAsp(异天冬氨酸)衍生物的过程。其它降解途径包括形成高分子量产物,其中两个或更多个蛋白质分子相互之间通过转酰氨基作用和/或二硫化物相互作用共价结合,导致形成共价结合的二聚体、低聚物和聚合物降解产物(Stability of Protein Pharmaceuticals,Ahern.T.J.&Manning M.C.,Plenum Press,New York 1992)。可提及氧化(例如蛋氨酸残基的氧化)作为化学降解的另一种变体。另外,因为高分子量蛋白(HMWP)产物为潜在免疫原性和无生物学活性,所以对于本公开的药物组合物来说低HMWP水平是有利的。
术语“I型糖尿病”,也称为胰岛素依赖性糖尿病(IDDM)和青少年型糖尿病,由B-细胞破坏引起,通常导致绝对的胰岛素缺乏。术语“II型糖尿病”,也称为非胰岛素依赖性糖尿病(NIDDM)和成人型糖尿病,主要与胰岛素抵抗因此相对胰岛素缺乏和/或胰岛素分泌不足为主伴有胰岛素抵抗有关。
本公开中表述“约”的误差范围为±10%至±20%。
术语“起效时间”是指自施用(例如皮下注射施用)本公开的药物组合物起至在血液中首次检出门冬胰岛素的时间。
术语“吸收速率”指PK曲线的斜率。
术语“精氨酸”或“Arg”包括精氨酸和/或其盐。
本公开中所涉及的药物辅料或试剂均可来自商业途径。
以下结合实施例进一步描述本公开,但这些实施例并非限制着本公开的范围。本公开实施例中未注明具体条件的实验方法,通常按照常规条件;或按照原料或商品制造厂商所建议的条件进行。未注明具体来源的试剂为市场购买的常规试剂。
实施例1药物制剂的制备
(1)按照表1的制剂组成配制一系列门冬胰岛素的制剂,制剂配制为含有活性成分以及锌离子(例如可加入乙酸锌或氯化锌等)、缓冲盐、防腐剂、等渗剂的水溶液。这些制剂用于后续实施例的稳定性、刺激性和药效动力学(PD)/药代动力学(PK)测试。
表1.门冬胰岛素的制剂组成
(2)将精氨酸浓度提高到6.96mg/ml(40mM)和13.92mg/ml(80mM),进一步考察稳定性;在倍他司汀处方中,倍他司汀设置了两个浓度5mg/ml和10mg/ml;在他氟前列素处方中,保持他氟前列素的浓度为3.75μg/ml;在伊洛前列素处方中,伊洛前列素设置了两个浓度10μg/ml和1μg/ml。具体制剂组成参见表2。
表2.门冬胰岛素的制剂组成
实施例2药物制剂化学稳定性的分析
研究实施例1制备的所有制剂均设置加或不加精氨酸的组,放置稳定性实验。化学稳定性以在40℃配样5天、10天和30天后内容物之间的差异测量的降解产物含量(%)表征,按照如下检测条件进行杂质检测。
有关物质检测条件
色谱柱型号:Sepax Bio-C18,4.0×250mm,5μm;
柱温:40℃;检测波长:214nm;流速:1.0ml/min;进样量:10μl;
流动相-以0.2mol/L硫酸钠缓冲液(称取无水硫酸钠28.4g于800ml水中溶解,加2.7ml磷酸,用4mol/L氢氧化钠溶液调节pH值至pH3.6,加水至1000ml,过0.45μm滤膜)-乙腈(90:10)作为流动相A;以50%乙腈作为流动相B,按表3进行梯度洗脱:
表3
从表4显示的高分子量蛋白、已知杂质(B3Asp+A21Asp+B3isoAsp+B28isoAsp杂质,表示B链第3位为天冬氨酸、A链第21位为天冬氨酸、B链第3位为异天冬氨酸及B链第28位为异天冬氨酸的杂质之和作为已知杂质之和,除此之外称为其他总杂)及其他总杂的检测结果看出:制剂L(倍他司汀)稳定性相对较好,但其他总杂增长较快,同时颜色发生改变,推测是在放置过程中,蛋白发生降解或与处方中其他物质反应,导致其他总杂增大;从液相中可以看出,制剂J(尼可地尔)中蛋白降解明显,在后续研究中被剔除;制剂B(伊洛前列素)和制剂F(他氟前列素)稳定性相对较好,主峰纯度降低稍多一点,但认为不构成显著性差异。
加入精氨酸后制剂稳定性有所提高,制剂C、G、K、M、U的稳定性各自优于相应的不含精氨酸的制剂B、F、J、L。
表4.门冬胰岛素制剂的化学稳定性数据
注:1、已知杂质:即已明确化学结构的杂质,本品中主要指B
28isoAsp门冬胰岛素、A
21Asp门冬胰岛素、B
3Asp门冬胰岛素、B
3isoAsp门冬胰岛素;2、其他总杂:即除了已知杂质以外的杂质的总和;3、高分子蛋白质:也叫高分子聚合物,主要指主成分或杂质以二个单元或多个单元聚合在一起形成的聚合物。
进一步研究了精氨酸浓度对制剂稳定性的影响,结果如表5所示。对于制剂D和E(门冬胰岛素+他氟前列素),当精氨酸浓度增加至40mM时,制剂较稳定,继续增加精氨酸浓度至80mM,从5天结果中分析,制剂稳定性无明显变化。对于制剂N、O、P、Q(门冬胰岛素+倍他司汀),制剂稳定性较差,其他总杂含量增加明显,增加精氨酸浓度也不能改善制剂稳定性。
实施例3药物制剂刺激性实验
对新西兰兔(n=5,购自邳州市东方养殖有限公司)单次皮下注射给予制剂C与H,单次注射100μL注射液(10个单位)后3天,大体解剖观察和组织病理学检查,观察其对注射部位及周围组织产生的刺激性反应。表6与表7为药物刺激性、过敏性和溶血性研究技术指导原则中皮肤刺激性的部分,参考该标准对本研究制剂刺激性进行评分。表8显示了刺激性评分结果。
表6.皮肤刺激反应评分标准
表7.皮肤刺激强度评价标准
| 分值 | 评价 |
| 0~0.49 | 无刺激性 |
| 0.5~2.99 | 轻度刺激性 |
| 3.0~5.99 | 中度刺激性 |
| 6.0~8.00 | 重度刺激性 |
表8.胰岛素制剂C与H的刺激性结果及评分
| 制剂 | 分值 | 评价 |
| C | 0.33 | 无刺激性 |
| H | 0 | 无刺激性 |
刺激性评分结果表明,制剂C与制剂H可视为无刺激性,并且含有伊洛前列素的制剂H的刺激性评分效果优于含有他氟前列素的制剂C。
实施例4药物制剂的动物PK/PD实验
在LYD(Land race,Yorkshire and Duroc)猪模型(50kg左右,单一性别,n=10,购自成都市牧童村农业开发有限公司)中进行药动学/药效学研究与血浆/血清分析测定。
适应期进行一次随时血糖监测和空腹血糖监测,试验期每轮试验先测定空腹血糖(禁食不禁水过夜),皮下注射给药,供试品不稀释。对照组给予制剂A, 实验组给予制剂C或H,给药剂量:采用微量注射器,1nmol/kg单次皮下注射。给药后1小时内再测定血糖12次(给药前及给药后3、6、9、12、15、18、24、30、36、48、60min)。
采血方法:取一根筷子粗的长绳,将绳的一端制成活套,套入猪的口腔上颌犬齿的后边,然后将绳拉紧并往上提,这时猪的注意力集中在鼻部,多呈后退姿势,从而保持安定的站立状态。在右侧胸前凹窝最低处用酒精棉球消毒后进针,有负压感且有回血,则标志已刺入前腔静脉,轻轻抽动注射器内芯采取血液。采血完毕,拔出针头,用棉球压迫止血。
血糖仪实时检测全血血糖:采血完毕后,滴取一滴全血于干净的表面,用血糖仪进行实时测量。
生化方法测定血清血糖:将采集的全血注入促凝管,待血液凝固后2500×g 4℃离心10min,取血清,用生化仪进行血糖测定。
于每轮给药后设12个时间点(给药前及给药后3、6、9、12、15、18、24、30、36、48、60min),采血方法同上,采集血液后注入EDTA-2K抗凝管中,6min、4℃、10,000×g离心分离血浆,得到100μL血浆,-80℃保存。
图1和图2分别示出了12个时间点的全血血糖检测结果和血清血糖检测结果,图3示出了给药前(0min,a)和给药后15min(b)和30min(c)的血清血糖检测结果,可以看出制剂C和H比对照组A显示出更快速的降血糖效果,且含伊洛前列素的制剂H比含他氟前列素的制剂C降血糖更快。
实施例5药物制剂的动物PK/PD实验
根据表9的制剂组成制备制剂R、S、T和U。根据实施例4的方法在LYD猪模型(50kg左右,单一性别)中进行药动学/药效学研究与血浆/血清分析测定。
表9.门冬胰岛素的制剂组成
制剂U与制剂S效果相当。
实施例6药物制剂的降血糖作用研究
12例男性受试者平均分成2大组,每组6人,各大组内双交叉试验(方案参见表10)。受试者于试验前一日进入Ⅰ期临床试验病房,按时提供标准餐和饮用水。给药前研究医生及研究护士双人核对受试者随机编码及药品编码,确认无误后方可给药。给药当天早7:00进食标准早餐,两小时后(早9:00)给药,给药后4小时内禁食不禁水。给药剂量为:0.2U/kg(0.002mL/kg),其中1ml胰岛素溶液含100U门冬胰岛素(相当于3.5mg)。
组(6例):研究护士用1ml注射器吸取
注射液于上臂三角肌下缘部位皮下注射给药,1min内给药完毕,研究医生现场监督实施。制剂S组(6例):研究护士用1ml注射器吸取制剂S于上臂三角肌下缘部位皮下注射给药,1min内给药完毕,研究医生现场监督实施。各受试者每次给药后间隔2天进行下一个周期的给药。
表10.交叉实验方案
据报道,
和普通
的起效时间分别为19min和29min,对应的门冬胰岛素起效血药浓度约为250pM;制剂S在15min时的平均血药浓度约为380pM,已超过了门冬胰岛素的起效浓度(或称有效浓度;参见图6);
制剂S在注射后0-33min的暴露量与
相当(236pmol×h/L Vs 226pmol×h/L);制剂S在注射后0-60min的暴露量高于
(623pmol×h/L Vs 544pmol×h/L)。
