Abstract
本發明提供一種顯示顯著之抗腫瘤效果,且副作用較少之FTD.TPI調配劑之新穎之併用療法。
本發明之抗腫瘤劑之特徵在於:將於第1天~第5天投予FTD˙TPI調配劑,於第1天投予CPT-11之14天1個周期之投予排程重複實施1次或2次以上。
Description
本發明係關於一種併用三氟胸苷(Trifluridine)與Tipiracil鹽酸鹽之調配劑、及伊立替康鹽酸鹽水合物而成之抗腫瘤劑、以及伊立替康鹽酸鹽水合物之抗腫瘤效果增強劑。
三氟胸苷(別名:α,α,α-三氟胸苷。以下亦稱作「FTD」)藉由胸苷酸生成抑制作用與藉由併入至DNA中所得之DNA合成抑制作用而發揮抗腫瘤效果。另一方面,Tipiracil鹽酸鹽(化學名:5-氯-6-[(2-亞胺基吡咯啶-1-基)甲基]嘧啶-2,4(1H,3H)-二酮鹽酸鹽。以下亦稱作「TPI」)具有胸苷磷酸化酶抑制作用。已知TPI藉由抑制由胸苷磷酸化酶所致之FTD之活體內之分解而增強FTD之抗腫瘤效果(專利文獻1)。目前,以莫耳比1:0.5含有FTD與TPI之抗腫瘤劑(以下亦稱作「FTD.TPI調配劑」)作為結腸直腸癌等實體癌之治療劑而在開發中(非專利文獻1及2)。
又,伊立替康鹽酸鹽水合物(以下亦稱作「CPT-11」)為以SN-38作為活性代謝物之喜樹鹼衍生物,藉由抑制拓撲異構酶I而抑制DNA之合成及轉錄,發揮抗腫瘤效果。CPT-11係於臨床上用作小細胞肺癌、非小細胞肺癌、子宮頸癌、卵巢癌、胃癌、結腸/直腸癌、乳癌、鱗狀細胞癌、惡性淋巴瘤等廣範圍之癌種之治療劑(非專利文獻3)。
進而,使FTD與SN-38對結腸直腸癌之細胞株發揮作用,結果確認到協同之細胞毒性,因此期待FTD.TPI調配劑與CPT-11之併用療法(非專利文獻4)。

本發明之課題在於提供一種顯示顯著之抗腫瘤效果,副作用較少之FTD.TPI調配劑之新穎之實體癌之併用療法。
本發明者鑒於此種現狀,如後述比較例般進行重複下述28天之周期之併用療法:基於各藥劑中已經報告效果之投予排程,對結腸直腸癌患者進行兩次投予FTD.TPI調配劑5天後停藥2天之操作,其後停藥兩週,兩週投予1次CPT-11,結果強烈地表現出副作用,因此CPT-11僅能投予預定量之30%左右。通常抗腫瘤效果與投予量之總計成比例,因此本發明者等人對抑制副作用之產生且可投予預定量之投予排程反覆進行研究,結果發現,對實體癌患者(尤其是結腸直腸癌患者)重複投予FTD.TPI調配劑5天後停藥9天,兩週投予1次CPT-11之14天1個周期之投予排程的併用療法抑制嗜中性球減少、腹瀉及體重減少等副作用之產生,可投予預定量,發揮優異之抗腫瘤效果。

本發明之FTD及TPI分別為公知之化合物,例如可依照國際公開第96/30346號說明書中記載之方法合成。又,亦公知有以莫耳比1:0.5含有FTD及TPI之調配劑(非專利文獻1及2)。
本發明之CPT-11為公知之化合物,可依據日本專利第3004077號公報所記載之方法合成。又,亦可使用Campto(註冊商標,養樂多
(Yakult)股份有限公司總公司)等市售品。
本發明之抗腫瘤劑之特徵在於將下述14天1個周期之投予排程重複實施1次或2次以上:於第1天~第5天投予以莫耳比1:0.5含有FTD及TPI之調配劑,於第1天投予CPT-11。
如後述參考例及實施例般,於將針對小鼠之單獨療法之推薦投予量之FTD.TPI調配劑與針對小鼠之單獨療法之推薦投予量之CPT-11依照上述投予排程併用投予至小鼠之情形時,可達成優異之抗腫瘤效果與副作用之抑制。因此,可明確本發明之投予排程中之FTD.TPI調配劑及CPT-11對人類之投予量為針對人類之FTD.TPI調配劑及CPT-11之單獨療法之推薦投予量。
即,第1天~第5天之FTD之投予量為20~80mg/m2/天,就抗腫瘤效果與副作用之平衡之觀點而言,更佳為40~70mg/m2/天,尤佳為70mg/m2/天。
第1天之CPT-11之投予量以伊立替康鹽酸鹽水合物計為50~200mg/m2/天,就抗腫瘤效果與副作用之平衡之觀點而言,較佳為100~180mg/m2/天,更佳為150~180mg/m2/天,尤佳為180mg/m2/天。
本發明之抗腫瘤劑之對象為實體癌,具體而言,可列舉:頭頸癌、消化系統癌(食道癌、胃癌、十二指腸癌、肝癌、膽道癌(膽囊癌、膽管癌等)、胰腺癌、小腸癌、大腸癌(結腸直腸癌、結腸癌、直腸癌等)等)、肺癌、乳癌、卵巢癌、子宮癌(子宮頸癌、子宮體癌等)、腎癌、膀胱癌、前列腺癌等。其中,就抗腫瘤效果與副作用之觀點而言,較佳為消化系統癌、肺癌或乳癌,更佳為結腸直腸癌、胰腺癌、胃癌、肺癌或乳癌,更佳為結腸直腸癌及胃癌,尤佳為結腸直腸癌。再者,此處實體癌不僅包含原發病灶,而且亦包含轉移至其他器官(肝臟等)之源自實體癌之腫瘤。又,本發明之抗腫瘤劑亦可為用於在外科摘除腫瘤後用以防止復發而進行之術後輔助化學療法者。
投予排程因各有效成分而不同,而無法將全部有效成分匯總為一種劑形而製成製劑,因此本發明之抗腫瘤劑係將各有效成分分成複數種劑形而製成製劑。FTD及TPI較佳為作為調配劑而製成製劑,CPT-11較佳為作為單劑而製成製劑。
又,只要根據本發明之投予排程投予各有效成分,則可將各製劑匯總至適於併用投予之1個包裝中進行製造銷售,又,亦可將各製劑分至個別之包裝進行製造銷售。
作為本發明之抗腫瘤劑之投予形態,並無特別限制,可根據治療目的適當選擇,具體而言,可例示經口劑(片劑、包衣片劑、散劑、顆粒劑、膠囊劑、液劑等)、注射劑、栓劑、貼附劑、軟膏劑等。FTD及TPI之調配劑較佳為經口劑,CPT-11較佳為注射劑。
本發明之抗腫瘤劑可根據其投予形態使用藥學上所容許之載體藉由通常公知之方法而製備。作為該載體,可例示通常之藥劑所通用之各種載體,例如賦形劑、結合劑、崩解劑、潤滑劑、稀釋劑、溶解助劑、懸浮劑、等滲劑、pH值調整劑、緩衝劑、穩定劑、著色劑、矯味劑、矯臭劑等。
又,本發明係關於一種抗腫瘤效果增強劑,其係以基於上述投予排程投予FTD.TPI調配劑及CPT-11為特徵,且含有用以增強針對實體癌患者(尤其是結腸直腸癌患者)之CPT-11之抗腫瘤效果之FTD.TPI調配劑。該抗腫瘤效果增強劑具有上述抗腫瘤劑之製劑形態。
又,本發明係關於一種抗腫瘤劑,其係以基於上述投予排程投予FTD.TPI調配劑及CPT-11為特徵,且含有用以對投予過CPT-11之實體癌患者(尤其是結腸直腸癌患者)進行治療之FTD.TPI調配劑。該抗腫瘤劑具有上述製劑形態。
又,本發明係關於一種試劑盒製劑,其包括FTD.TPI調配劑、及記載有基於上述投予排程投予FTD.TPI調配劑及CPT-11之使用說明
書。此處所謂「使用說明書」,只要為記載有上述投予排程者即可,不論有無法律上之約束力,均較佳為推薦上述投予排程者。具體而言,可例示隨附文件、說明書等。又,所謂包含使用說明書之試劑盒製劑,可為於試劑盒製劑之包裝上印刷、隨附有使用說明書者,亦可為使用說明書與抗腫瘤劑一同附於試劑盒製劑之包裝中者。
其次,列舉實施例進一步詳細地說明本發明。
將人類大腸癌株(KM20C)之培養細胞(1×107個細胞/小鼠)移植至出生後5~6週之BALB/cA Jcl-nu小鼠之腹腔內,以各組之平均體重均等之方式將小鼠分攤至各組,將實施分組(n=10)之日設為第0天。
FTD.TPI調配劑(FTD與TPI之莫耳比1:0.5之混合物)係以FTD成為75mg/kg/天、100mg/kg/天、150mg/kg/天、300mg/kg/天及450mg/kg/天之方式而製備。由於伊立替康鹽酸鹽水合物(CPT-11:Campto註(註冊商標),養樂多股份有限公司總公司)以111mg/kg/天報告有死亡例(基礎與臨床(1990),Vol.24、No.14、7~17),因此以伊立替康鹽酸鹽水合物成為80mg/kg/天及100mg/kg/天之方式而製備。藥劑之投予係自第3天開始,FTD.TPI調配劑係將連續5天經口投予、停藥2天的操作進行6週,CPT-11係將1週1次之自尾靜脈之投予進行6週。
作為抗腫瘤效果之指標,確認各組之小鼠之生存數,比較各組之生存期。將結果示於表1。
如表1中記載般,對於小鼠,CPT-11於100mg/kg/天之組中生存期較長,小鼠中之CPT-11之推薦投予量(RD)為100mg/kg/天。因此,小鼠中之100mg/kg/天相當於人類中之RD 150~180mg/m2/天。
對於FTD.TPI調配劑,於以FTD換算量計為150mg/kg/天之組中生存期較長,因此小鼠中之FTD.TPI調配劑之RD以FTD換算量計為150mg/kg/天。因此,小鼠中之150mg/kg/天(FTD換算量)相當於人類中之RD 70mg/m2/天。
將人類大腸癌株(KM20C)移植至出生後5~6週之BALB/cA Jcl-nu小鼠之右側胸部。於移植腫瘤後測定腫瘤之長徑(mm)及短徑(mm),算出腫瘤體積(tumor volume:TV)後,以各組之平均TV均等之方式將小鼠分攤至各組,將實施分組(n=6)之日設為第0天。
FTD.TPI調配劑(FTD與TPI之莫耳比1:0.5之混合物)係以FTD成為150mg/kg/天之方式而製備。伊立替康鹽酸鹽水合物(CPT-11:Campto(註冊商標),養樂多股份有限公司總公司)係以伊立替康鹽酸鹽水合物成為100mg/kg/天之方式而製備。於投予排程(1)中,FTD.TPI調配劑係於第1-5天及第8-12天連日經口投予,CPT-11係於第1天及第15天自尾靜脈投予。於投予排程(2)中,FTD.TPI調配劑係於第1-5天及第15-19天連日經口投予,CPT-11係於第1天及第15天自尾靜脈投予。FTD.TPI調配劑及CPT-11之單劑投予組係以與併用投予組中之對應之藥劑相同之投予量及投予排程進行投予(圖1)。
作為抗腫瘤效果之指標,算出於各組中第29天之TV,藉由下式求出相對於第0天之相對腫瘤體積(relative tumor volume:RTV),並與無
處理組(control)之RTV進行比較。關於併用效果之評價判定,於併用投予組之平均RTV值較各個單獨投予組之平均RTV值於統計學上顯著(Welch’s IUT,整體最大p<0.05)較小之情形時,判定為有併用效果。將結果示於圖2及圖4。圖中,於p值為0.05以下之情形時,顯示相對於單獨投予組確認到統計學上顯著之差異。
TV(mm3)=(長徑×短徑2)/2
RTV=(第29天之TV)/(第0天之TV)
又,作為毒性之指標,經時測定體重[body weight:BW],藉由下述式算出第n天相對於第0天之平均體重變化率[body weight change:BWC(%)](n:以2次/週實施之體重測定日,最終測定日相當於作為最終評價日之第29天),並且於試驗期間觀察各個小鼠之腹瀉。將結果示於圖3及圖5。
根據圖2~圖5之結果可知,投予排程(2)與投予排程(1)相比,維持抗腫瘤效果,並且體重減少及腹瀉之副作用明顯改善。
依照實施例1將細胞株替換為人類胃癌株(SC-2)進行FTD.TPI調配劑與CPT-11之併用投予試驗。FTD.TPI調配劑(FTD與TPI之莫耳比1:0.5之混合物)係以FTD成為75mg/kg/天及150mg/kg/天(推薦投予量)之方式而製備,CPT-11係以伊立替康鹽酸鹽水合物成為100mg/kg/天(推薦投予量)之方式而製備。將結果示於表2。
如表2所示,對於胃癌,亦確認到藉由投予排程(2)而顯著地增強抗腫瘤效果。又,體重減少亦為可容許之範圍內。
