200817432 九、發明說明: 【發明所屬之技術領域】 敘述 本發明是關於甘精膜島素經酸胺化修飾,特別是在 Gly(A21),Arg(B31),Arg-醯胺(B32)人類胰島素(甘精騰 島素醯胺)。 【先前技術】 10 15 世界上大約有1.77億名糖尿病患者,其中一億七千 萬人是屬於第一類型糖尿病,取代其所缺乏之胰島素分泌 是目前唯一可行的治療方法,那些患者需要依賴通常一天 要好〃幾次的胰島素注射,終其一生。不同於第一型糖尿 病,第二型糖尿病並非總是缺乏胰島素,但是在大部分的 木例中尤其疋在後期階段,用胰島素和口服抗糖尿病猝 結合的治療被認為是最有力的治療類型。 市 健康的人之中,騰臟貝他細胞(bda⑶η)所釋放 2二、,血液中葡萄糖濃度有著嚴謹的關聯。A糖濃度提 ====生的㈣,純速的被料量提升分= —會; 島素敏感之哭官盥&础 卞行、貝仏、、、口匍甸搪至胰 低產量。通常持肝臟中葡萄糖於 素分泌,多半無素取代内生性的騰島 切契合,一曰樓尸/二*液中葡甸糖生理調控的品質密 —搪尿病患者錯誤地調節各別的情況,血液中 20 200817432 葡萄糖含量升降的擾動便會顯得頻繁,然而,除此之外, 血中葡萄糖含量長年升高,既使沒有初始徵兆,也代表健 康上相當大的危機。在美國大規模的糖尿病控制及併發症 臨床研究計畫(DCCT) (The Diabetes Control and 5 Complications Trial Research Group (1993) Ν· Engl· J· Med· 329, 977-986)清楚地證實,慢性血糖含量的提升與後期糖 尿病併發症有實質上的關聯。微血管或大企管病變屬於晚 f 期糖尿病併發症,在一些情形中會造成如視網膜病變 (retinopathy)、腎病變(naphropathy)、神經病變 10 (neur〇pathy),會導致失明、腎衰竭、失去四肢,此外也 與增加心血管疾病的風險相關。因此,可以推斷一個改進 的糖尿病治療法必須主要針對於盡可能保持血糖在生理 的範圍之内。改進的胰島素治療策略試圖藉由一天注射許 多次速效與緩效型胰島素調劑已達成此目的。速效型的配 15 $是在用餐時間針,以求補償用餐過後提升的血糖。緩 ( 效型基本胰島素則是用於確保基本量騰島素的供應,特別 是在夜間,避免造成低血糖。 胰島素是由一段51個魏酸所分成之兩段胺基酸鏈 所構成之多肽鏈:A鏈具有21個胺基酸,而b鍵呈有% 2〇 _基酸,兩條鏈由二個雙琉鍵相連結。為了糖尿病的户 療,胰島素製備已被使用了好幾年,此外,不只是使用^ 然之胰島素’還包括近年來許多胰A素⑽生物或類似 物。 胰島素類似物是天然姨島素,亦即人類胰島素或動物 200817432 胰島素的類似物,差別在於以其他胺基酸取代至少一個天 然的胺基酸,或是增加/刪除至少一個胺基酸在相對應的 位置,否則就完全相同的天然胰島素上。例如美國專利第 5656722號是描述甘精胰島素(Arg(B31),Arg(B32), Gly(A21)人類胰島素),那些添加或取代的胺基酸可能也 不是自然發生者。 胰島素衍生物是天然胰島素或類胰島素的衍生物,其 一個或多個胺基酸或A鏈與b鏈的N端或C端被其他官 能基所取代’而官能基是由下列基團所選出,其包括醯胺 基、胺基、羧基、烷基、醇基以及烷氧基。 一種有效率的胰島素療法使用所謂的基本胰島素 (basal insulin),此模式使緩慢而持續釋放外加調控胰島素 成為可能。如此一來,糖尿病患者體内的基本胰島素濃度 可達到對生理有利的情況很長一段時間。理想上,胰島素 影響的起始點可以延後’時間與影響力的關係曲線可以儘 可能平缓,如此一來,短期血糖缺乏的危險可以明顯降 低,並可在先前未進食的情況下進行調控。 重組類胰島素Arg(B31),Arg(B32),Gly(A21)人類胰 島素(甘精胰島素;US5656722)是與許多每24小時,也就 是每天只有一次需要供給的病人相聯結,為了達到基本的 影響,對血糖的控制有所改善,例如導致醣化血色素 (Hbalc)含量的減少。 如今,一個驁人的發現顯示甘精胰島素B32位置之 精胺酸文醯胺化所產生所謂甘精胰島素醯胺(insulin 200817432 ΤΙ7^7Τ^ ίΓ11" ^ ^fa1 ^m Μ # 3"11 ^ ^ 低沒有標定的^ 有利。在初始時,血糖濃度的降 音 氐點(耶出1〇,此顯示經醯胺化之甘精胰島 ^ 的敏感度具有驚人的優異品質。在低血糖調控 一、二因此減少。投予蘭德仕醯胺(Lantus amide)建立 、正㊆血糖值為7G_11G毫克/百毫升_萄糖。此外,經驢 之Γ精胰島素相較甘精胰島素具有更驚人長效的影 曰if發明因此與經醯胺化之甘精胰島素有關。 ίο 二ί "亥項技藝的工作者因此對經醒胺化之甘精胰島 =與鲁,配方的_很清楚。這意指—個醫藥混合物在調 以最好的方式,最佳的展現經醯胺化之甘精胰島素的 心音力。以水溶液作為此聯結的基礎,其餘組成份必須是 適合溶混的。製備中不包含任何成分是來自動物性來源, 此乃一大利處,病毒污染的危險因而減少,加入防腐劑是 對阻止微生物污染更有益的方式,可能可以透過添加等滲 劑以補償調節位置組織細胞之生理狀態的負面影響,添加 魚精蛋白(protamine)可能具有穩定的效果,因此可以規劃 魚精蛋白的添加以製備無鹽胰島素,添加酚類組成物可導 致類胰島素中六聚體結構的穩定,因此有利於對作用起始 的遲延’經醯胺化之甘精胰島素的供給可與速效型胰島素 並行’例如Apidra®、NovoRapid®,Humalog®或胰島素衍生 物’以相同的時間/活動量表曲線經歷發展與規劃。為此, 熟悉該項技藝的工作者能清楚認知適當地製備個別胰島 素組成分子之混合物也可被用在此目的,醯胺可以更佳地 200817432 被使用如Exubera®等吸入式胰島素的人所取得,經醯胺 化之甘精胰島素可進一步用於醫藥上的製備,包含一段被 描述為活性可與GLP-1 (似騰高血糖激素-1)相比擬的多肽 鏈,此多肽鏈可例示於 GLP-1(7_37),Exenatide (Byetta®), 5 或是製備法被描述於WO 2006/058620、WO 2001/04156 與WO 2004/005342等專利申請案之胜肽。 與本案同日申請之標題為“製備具有二元B鏈端的胰 , 島素類似物之方法”之專利申請案主要是描述經醯胺化之 甘精胰島素之製備方法,利用胰蛋白酶催化接合精胺醯胺 10 (argininamide)到 Gly (A21),Arg(B31)人類胰島素,可以 獲得很高的產量。在這個例子中,可能可以控制反應,以 得到胰島素類似物Gly(A21),Arg(B31) , Arg (B32)-醯胺 等較佳的產物,在文獻中有些描述特別提到,保護後的精 胺酸衍生物在許多溶劑内常常都不穩定,對產率有正面幫 15 助的方法可能可以藉由改變保護基或醯胺基等方式改變 反應條件,這些對技術人員是很熟悉的,亦與本發明有 、 關。US 5,656,722是描述表現以微小前胰島素 (miniproinsulin)為組成分子之融合蛋白質的pB40盘 PINT91d等質體,將胰島素A鏈之21號位置天門冬胺酸 20 以甘胺酸取代,使得Arg(B31),Gly (A21)迷你胰島素前 驅物直接由融合蛋白質中製備出來,而其可藉由胰蛋白酶 消化直接轉變為經酿胺化之甘精胰島素的前驅物。相對應 的融合蛋白質不需要細胞中製備,熟練的技術人員能清 楚,胰島素前驅物之相似物可藉由細菌表現及隨後分泌至 9 200817432 膜周圍及培養上清液中’以歐洲專利申請案Ηρ-A 1 364 029為例子來描述此方法。此發明同時也與人類胰島素前 驅物Arg(B31),Gly (A21)人類胰島素前驅物的使用有 關,其可直接透過此頡細菌方法表現來產生。 5 胰島素類似物的醯胺化可普遍發生在許多方面。C端 羧基受醯胺化之甘精胰島素稱為甘精胰島素醯胺。 更讓熟練的技術人員熟悉的是,經由此例所描述的表 : 現系統僅代表宿主/載體系統為製備嵌合蛋白質的小片 段,宿主/載體系統允許製備目標多肽鏈因此也成為這個 10 發明的一個部分。 【發明内容】 本發明因此是關於經醯胺化之甘精胰島素,特別是經 醯胺化之甘精胰島素 Gly(A21),Arg (B31),Arg(B32)-NH2 15 人類胰島素的型式(甘精胰島素醯胺)。 本發明更進一步與經醯胺化之甘精胰島素製備之方 \ 法有關,特別是甘精胰島素醯胺,經醯胺化之甘精胰島素 的前驅物為形式Gly(A21),Arg (B31)的人類胰島素被重 組製備,在具有胰蛋白酶活性的酵素存在下,與精胺醯胺 20 (argininamide)的偶合發生,P遺後甘精胰島素醯胺便得以被 純化出來。 本發明進一步關於甘精胰島素醯胺於製造用於治療 糖尿病,特別是第一型或第二型糖尿病之醫藥品之用途。 本發明又進一步關於一包含甘精胰島素醯胺之藥 200817432 物,特別是水性調配物或粉末。 此藥物是一醫藥製劑,其較佳以溶液或懸浮物型態存 在,有助於注射的目的;其特徵在於至少有一種醯胺化之 甘精胰島素,特別是甘精胰島素醯胺,及/或是至少一種 5 在溶解狀態、非結晶狀態,及/或是結晶狀態-較佳的型態 為溶解狀態之生理上可耐受性的鹽類。 此製劑較佳的pH值介於約2.5至8.5,特別是介於約 , 4.0到8·5之間, 包含一個合適的強化劑(tonicity agent), 10 適合的防腐劑 和適當缓衝液, 較佳也使用某一辞離子濃度, 整個自然地在無菌水溶液中。除活性成分外,製劑的載體 形成一個整體的製劑成分。 15 適合的強化劑為例如甘油、葡萄糖、甘露醇、氯化納、 鈣或鎂化合物如氯化鈣等。 經醯胺化之甘精胰島素或其生理上可耐受性的鹽類 之溶解度受在弱酸性pH值的強化劑和/或防腐劑的選擇 之影響。 20 合適的防腐劑為,例如酚,間-甲苯酚,苄醇和/或對 -羥基苯曱酸酯。 缓衝物質,可以使用特別設置pH值介於約4.0和8.5 之間者,例如醋酸鈉、擰檬酸鈉、磷酸鈉等,否則,接受 生理可接受稀釋酸(典型為鹽酸)或鹼(典型為氫氧化鈉), 11 200817432 也適合用於設立pH值。 古^果^含有鋅’其含量為從1微克/毫升至2毫克/ 笔升f i尤其是從5微克到200微克鋅/毫升較佳。 . 心/、\發明製劑之不同活性成分,它也可能是混合了未 二之月島素,較佳是牛、豬或人胰島素,特別是人胰島 ”或胰島素類似物與其街生物,它同樣可能混合一個或多 個exendm-4彳叮生物或胜肽,其特點在於其相較於 f GLP-IQ員騰南企糖激素力之活性,本發明同樣涉及到這 種藥物(製劑)。 1〇 優選的活性成分的濃度是那些大約相當於 1 -
