1362260 (1) 玖、發明說明 【發明所屬之技術領域】 本發明係有關L -肉毒鹼及烷醯基L -肉毒鹼在製備可 用於治療腫瘤之藥物上的應用,尤其是與抗癌劑結合使用 【先前技術】 已使用在人類醫療中使用抗癌劑會導致許多毒性或副 作用,而可能對於患者之生活形成威脅。此等倂發症實際 上可能導致藥物劑量減低,有時可能會使治療本身中斷。 劑量減低或中斷治療在許多情況下皆會傷及個體之一 般狀況,因爲此種情況有利於舊疾復發,結果有時會危及 患者之生命。 在醫院設置及腫瘤患者家庭中有另一極重要且感受極 強的層面就是「改善治療中之患者的生活品質」的觀念。 同樣已知進行癌症之一般綜合化療之患者的體重大幅 減輕。 人類醫療中使用之抗癌劑的數目及重要性日漸增加( 主要限制係產生毒性或副作用)表示此項問題仍相當重要 〇 因此,極期望可發現可大幅降低因爲人類醫療中所使 用之抗癌劑導致之毒性或副作用的新穎藥物或不同藥物之 新穎組合物。 L-肉毒鹼與抗癌劑結合使用係先前已知。 (2) (2)1362260 在實驗動物模型中,證明單獨使用阿黴素( doxorubicin)治療之白鼠所減輕之體重大於使用相同物質 與 L -肉毒驗結合來進行治療之白鼠(Senekowitsch R, Lohninger A 5 Kriegel Η., Stani ek Η. 5 Krieglsteiner HP.. Kaiser E. Protective effects o f carnitine on adriamycin toxicity to heart. In: Kaiser E., Lohninger A .. ( e d s .). Carnitine: its role in lung and heart disorders: 1 2 6- 1 3 7. Karger, Basel-New York, 1 9 8 7 )。 美國專利第4,713,370號描述肉毒鹼與細胞生長抑制 劑(諸如柔紅黴素、N-乙醯基柔紅黴素及柔紅黴素肟)結 合使用,以降低此等化合物之心臟毒性。美國專利第 4,26 7, 1 63號描述肉毒鹼與細胞抑制劑(諸如阿黴素( adriamycin )、阿黴素-1 4辛酸酯、4表阿黴素、阿黴素 異頭物及4’-表阿黴素異頭物結合使用,以降低此 等化合物之心臟毒性。美國專利第4,751,242號描述乙醯 基肉毒鹼用於治療末稍神經病變之應用。後一專利中 ’末稍神經病變係定義爲腦幹及脊髓之運動神經元及/或 原發性感覺神經元及/或末稍自主神經元之持續性失調, 包括末稍神經元及其附帶之支撐結構。就其病因而言,末 梢神經病變構成異質疾病,因爲其病因可能是繼發性到病 毒感染(帶狀泡疹)、局部缺血(動脈硬化)、代謝不平 衡(糖尿病、腎及肝功能不足)、藥物-誘發之毒性(阿 黴素、異菸酸肼、硝基呋喃妥因)、機械應力(壓迫、受 壓 '骨骼斷裂或脫位)、輻射、遺傳因素及免疫系統病因 -6 - (3) (3)1362260 。然而,不論疾病形成之實際病因爲何,始終可偵測到因 爲細胞脂質、膽固醇及神經結糖苷之改變所導致之膜流動 性改變。脂質在界定三級及四級蛋白質濃縮及保持嘌呤核 苷三磷酸酯酶結構之安定性中扮演著極重要之角色。實際 上,若無脂質,則導致酶失活。就此言之,假設乙醯基 N-肉毒鹼可能對於自由基(超氧化物、過氧化氫化物)產 生「淸除劑」作用,該等自由基係於不規則或不充分灌流 或於發炎過程中,因爲控制介於四價及雙價厭氧路徑之間 的代謝變化之細胞色素氧化酶的活性降低而形成。乙醯基 L -肉毒鹼藉著增加還原穀胱甘肽(最重要之抗氧化劑代謝 物中之一)的濃度,且可能增加細胞色素氧化酶之濃度, 可能產生自由基淸除效果,並大體上恢復四價氧化-還原 劑呼吸機制,尤其是神經元者。而且,乙醯基L-肉毒鹼 會因爲增加ATP-酶及AChE (最佳神經傳遞所必需)而影 響神經元。 其他硏究係有關肉毒鹼對於由绡環類抗生素所誘發之 心臟毒性的保護效果的評估(Neri B., Comparini T., Milani A., Torcia M., Clin. Trial J. 20, 98- 1 03, 1 983; De Leonardis V., De Scalzi M., Neri B., et al. Int. J. Clin. Pharm. Res. 70, 307-311, 1987)。 前述專利及所列之圖書參考資料說明許多嘗試降低抗 癌劑之毒性或副作用的努力,但尙未令人滿意地解決此項 嚴重問題。 碳鉑係爲順氯氨鉑之結構同質物,而其所帶之腎毒性 (5) 1362260 微管係爲保持細胞形狀、各種細胞作用及軸 必要要素。神經元及軸突中之微管功能不全可能 化學療劑之神經毒性的來源。 紫杉鹼主要誘發全身分佈之感覺末梢神經病 情況同時與藥物之單一及累積劑量有關,可能與 有關。紫杉醇之神經毒性係起因於獨特之作用機 結於微管蛋白且促使微管組成(Schiff ?.8.等乂 1 9 7 9; Parnass J. and Horowitz S.B., J. Cell. Bic 。在紫杉醇存在下所形成之微管在一般會將其解 下(包括存有鈣及寒冷)保持安定性。帕克 paclitaxel )亦改變微管組合之動力學,去除了 始組合之前所發現之遲滯期(Horowitz S.B.等 N.Y. Acad. Sci. 1 9 8 6 )。此種機制與抑制微管組 花生物鹼的機制競爭。 此種競爭性機制使得難以發現一種同時作用 同方式誘發之神經病變的藥物。 使用不具有骨髓毒性之造血生長因子,神經 劑量-限制因子(Schiller等人,J. Clin. Oncol. 症狀可能早在使用高値單一劑量(>250毫克/为 之後的24至72小時開始出現,但神經毒性一般 ,在高及低劑量下,每次治療之後症狀皆持續惡 該症狀通常可忍受(NCI第1或2級)。神 測定性地顯示高値臨界値,且於末稍、對稱、字 襪模式下感知振動。通常,大纖維感覺實體(振 漿轉運之 是該兩類 變,此種 投藥方案 制;其鍵 、* Nature )1. 1981) 聚的條件 里塔西( 一般在開 人 5 Ann. 合之長春 於兩個不 毒性變成 1 994 ) <» t 2 )治療 是累積性 化。 經系統檢 :套-及·長 動,本體 -9- (6) (6)1362260 感覺)較喪失小纖維感覺實體(疼痛,溫度)更常受到影 響。亦常影響腱反射,固定沒有或降低末稍(踝)反射。 神經傳導硏究顯示感覺神經作用電位幅度以對稱、末 端、與長度有關之方式降低。有症狀之患者之緋腸感覺神 經作用幅度實際上始終較低或不存在。 輕度感覺症狀通常在停用紫杉醇後之數個月內改善或 完全舒解。 順氯氨鉑誘發末稍感覺軸突神經病變,影響大直徑及 (較輕微地)小直徑感覺纖維。感覺異常及受損之本體感 受是最吊見之症狀(Thompson S.W.等人,Cancer 1984) 。順氯氨鉑累積於且損壞背根神經,在神經元受損之後產 生軸突變化(Warner E·,Int. J. Gynecol. Cancer 1995) ο 由順氯氨鉑誘發之神經病變的發生與累積劑量極有關 係,症狀係開始於順氯氨鉑總劑量爲3 3 0至4 0 0毫克/ 米2時。順氯氨鉑緊密且不可逆地鍵結於神經組織,這 說明了有時在順氯氨鉑療法停止之後發生神經受損之情況 〇 長春花生物鹼誘發末稍感覺-運動綜合神經病變及自 主神經病變,此等病變在數個月後有部分可逆(Potsma T . J .等人,J N eu r ο ο n c ο 1 1 9 9 3 )。 伊波提酮家族具有類似紫杉烷之毒性曲線(Lee FY 等人 Proc Am Assoc Cancer Res, 2002,792 )。 使用於癌症治療之數種其他化合物亦出現輕度至嚴重 -10- (13) (13)1362260 N-肉毒鹼之整體保護活性(兼指預防及治療)係出乎於以 技術經驗所預測者之外。如同背景部分所討論,推測乙醯 基L -肉毒鹼似乎藉著增加還原穀胱甘肽之濃度,而對自 由基產生「淸除劑」效果。該段落亦說明本發明硏究之抗 癌藥物損壞末稍神經的機制。就鉛家族而言,亦已知還原 淸除劑易影響藥物活性’因其係經由自由基機制作用,故 不建議使用自由基淸除劑。 乙醯基L-肉毒鹼(ALC )藉著強化神經生長因子( NGF)之效果,來產生對抗因爲抗癌劑誘發之末稍神經病 變的保護效果(Gacaletti,G.等人,Journal of Neurology, Vol. 249, Suppl. 1,June 2002: 1/28,78) 。NGF 在技術 界係已經徹底硏究而與順氯氨舶及紫杉醇神經毒性有關之 神經保護劑。乙醯基L-肉毒鹼可藉著促進不同基因之表 現,而強化NGF對於PC 12細胞之影響,如同微量陣列( microarray)分析所評估,亦記錄在促進PC12神經炎發 展時的NGF與乙醯基N-肉毒鹼之間的關係。在由順氯氨 舶所誘發之慢性感覺神經病變的動物模型中發現介於乙醯 基L-肉毒鹼與NGF之間的不同關係。此模型中,感覺神 經病變開始與NGF循環濃度降低量之間有一先前已證明 的密切關係。 在使用紫杉醇-乙醯基L-肉毒鹼治療組中的紫杉醇神 經毒性活體內模型中亦發現神經病變之嚴重性大幅降低。 除了在經順氯氨鉑治療之動物體內降低NGF之外,乙醯 基L-肉毒鹼似乎增加細胞對於NGF之反應。有關基於乙 -17- (14) (14)1362260 醯基L-肉毒鹼之保護效果的分子機制,本發明所進行之 硏究顯示保護劑經由組蛋白乙醯化(與基因表示之調節有 關)來促進神經元NGF反應。乙醯基L -肉毒鹼之乙醯基 係於NGF-歧化PC12細胞中轉移至組蛋白。乙醯基L_肉 毒鹼之存在增加由NGF誘發之組蛋白乙醯化。而且,添 加乙醯基L-肉毒鹼於PC12細胞明顯刺激NGFI-A (具有 腫瘤抑制效果之轉錄因子的基因編碼)之表現。此外, NGFI-A蛋白質參與數個生理過程,顯然在組織修補中具 有重要角色。結果,本發明顯示乙醯基L-肉毒鹼係爲針 對於在使用本發明所硏究之抗癌劑治療之後的化學療法誘 發神經病變的特定保護劑。與此點有關的是不會對藥物抗 腫瘤活性產生任何干擾。最後,乙醯基L·肉毒鹼可在化 學療法誘發之神經病變中促進生理NGF之支持效果,因 此避免外在投予NGF之局部及整體副作用問題,此問題 係爲此種神經保護策略的主要問題。 當ALC使用於本發明時,未發現對藥物之抗癌作用 產生任何負面影響。 ALC可簡便地經口投藥,但不因此排除熟習此項技術 者可能建議採用之其他投藥路徑,特別是注射,以於(例 如)相同輸液管瓶中與抗癌劑同時投藥,或依序投藥,如 同熟習此項技術者已知。 因爲L-肉毒鹼及其他烷醯基L-肉毒鹼(以下總稱爲 「肉毒鹼」),尤其是丙醯基L-肉毒鹼(PLC),同時顯 示療效與抗癌劑治療活性,如前述WO 00 / 06 1 3 4所揭示 -18- (15) (15)1362260 ,故較佳係提供作爲保護劑之乙醯基L-肉毒鹼及一或多 種「肉毒鹼」與本發明抗癌劑之組合物(亦爲個別劑型, 或有時爲結合劑型)。根據本發明組合的結果,此種組合 物亦可包含其他抗癌劑,此劑誘發實質減輕之副作用,尤 其是末稍神經病變。後一具體實例有利於綜合化學療法。 添加L-肉毒鹼於前述組合物中亦佳。 因此,更佳係提供一種三元組合物,其包含個別劑型 或有時結合劑型之作爲保護劑的乙醯基L -肉毒鹼、作爲 協合劑之丙醯基L -肉毒鹼、及本發明抗癌劑中之一。根 據本發明組合之結果,此種組合物亦包含其他顯示協合效 果或誘發實質減輕之副作用的抗癌劑。後一具體實例有利 於綜合療法。添加L -肉毒鹼於前述組合物亦佳。 本發明之一特定目的係爲一種醫藥組成物,其包含治 療有效量之本發明抗癌劑中之一與保護量之乙醯基L-肉 毒鹼及協合量之乙醯基L -肉毒鹼,其與醫藥上可接受之 佐藥及/或賦形劑混合。 就與工業應用有關之層面而言,本發明亦於其可能具 體實例中之一中提供一種套組,其含有a) —種醫藥組成 物’其包含治療有效量之抗癌劑;b) —種醫藥組成物, 其包含乙酿基L -肉毒驗或其醫藥上可接受之鹽,用量係 適於產生對抗該抗癌劑對末稍神經系統之副作用的實質保 護作用。本發明套組亦可爲包含下列者之形式:a ) 一種 醫藥組成物,其包含治療有效量之抗癌劑;b) —種醫藥 組成物,其包含乙醯基L -肉毒鹼,用量係適於產生對抗 -19- (16) (16)1362260 該抗癌劑對末稍神經系統之副作用的實質保護作用。 套組之指導說明參照前述WO 00/6134,尤其是與其 他肉毒鹼組合時。 現在參照較佳具體實例揭示進行本發明之方式,使用 草酸鈾(Oxaliplatin)、或伊波提酮(epothilone)或唯 諾賓(Vinorelbine)作爲抗癌劑。 已知熟習此項技術者可依其本身之技術常識完成實驗 方案,可能視需要再分成兩相鄰部分》 下文中記錄適於說明藉著結合L-肉毒鹼或其衍生物 與前述抗癌劑所得之令人意外且令人驚異的保護效果之最 重要實驗的結果。實驗細節可參考WO 00/6134及此申 請案所列之文獻。
