本発明の副作用低減剤は、イソロイシン、ロイシン、及びバリンから選ばれる少なくとも1種の分岐鎖アミノ酸又はその塩を有効成分とし、キナーゼ阻害剤の副作用を低減させることを特徴とする。本発明の副作用低減剤は、イソロイシン、ロイシン、バリンのいずれか1種以上が分岐鎖アミノ酸として含有されていれば良く、イソロイシン、ロイシン、バリン全てが含有されていることが好ましい。
本発明の抗癌用医薬は、イソロイシン、ロイシン、及びバリンから選ばれる少なくとも1種の分岐鎖アミノ酸又はその塩(すなわち、本発明の副作用低減剤)と、キナーゼ阻害剤と、を組み合わせてなり、癌の治療のために投与対象に投与されることを特徴とする。本発明の抗癌用医薬は、本発明の副作用低減剤とキナーゼ阻害剤とを一の製剤としたものであってもよく、それぞれ別個の製剤として組み合わせたものであってもよい。
本発明の抗癌用医薬には、癌を治療する医薬のみならず、癌の発症・進展を抑制する医薬も含まれる。
本発明の副作用軽減剤及び抗癌用医薬において、分岐鎖アミノ酸の投与量(摂取量)は、患者の病態、年齢、投与方法などによって異なるが、通常、1人あたり1日、イソロイシン0.5~30.0g、ロイシン1.0~60.0g、バリン0.5~30.0gである。一般の成人の場合、好ましくは1人あたり1日、イソロイシン2.0~10.0g、ロイシン3.0~20.0g、バリン2.0~10.0g、より好ましくは、イソロイシン2.5~3.5g、ロイシン5.0~7.0g、バリン3.0~4.0gである。イソロイシン、ロイシン、バリン全てが含有されている場合は、成人1日あたりの投与量が3種の分岐鎖アミノ酸の合計量として、通常2.0~50.0g程度が好ましく、これを必要に応じて1~6回、好ましくは1~3回に分割して投与する。
1回投与当たりの分岐鎖アミノ酸の配合量は、通常0.5~50.0g程度、好ましくは1.0~20.0g程度、より好ましくは2.0~6.0g程度とする。
イソロイシン、ロイシン、及びバリンから選ばれる少なくとも1種の分岐鎖アミノ酸又はその塩(すなわち、本発明の副作用低減剤)を、例えば有効量のキナーゼ阻害剤製剤とそれぞれ単味剤として組み合わせて、一体包装されるような医薬用キットとすることができる。
CDAA(コリン欠乏アミノ酸添加)食誘発肝癌モデルラットを用いて、ソラフェニブと分岐鎖アミノ酸(BCAA)の併用摂取による効果を調べた。CDAA食は市販品コリン欠乏食(♯518753:Choline Deficient and iron Supplemented L-Amino Acid Defined Rat Diet、Dyets社製)を用いた。
6週令のFischer344系ラットをCDAA食摂取群、ソラフェニブ単独摂取群、及びBCAA併用摂取群(各群:N=15)に分け、実験食を自由摂食させた。実験食として、CDAA食摂取群にはCDAA食のみを供与した。ソラフェニブ単独摂取群には、CDAA食に、体重当たりのソラフェニブの摂取量が16mg/kg/日(800mg/50kg/日)になるようにソラフェニブトシル酸塩錠(ネクサバール(登録商標)錠200mg、バイエル薬品社製)を混合したもの(以下、「CDAA/ソラフェニブ食」)を供与した。BCAA併用摂取群には、ソラフェニブ単独摂取群に供与したCDAA/ソラフェニブ食に、さらに、含有量が2.5質量%になるようにBCAA製剤(リーバクト(登録商標)顆粒、味の素社製)を混合したもの(以下、「CDAA/ソラフェニブ/BCAA食」)を供与した。なお、当該BCAA製剤のイソロイシン、ロイシン、バリンの重量比は、1:2:1.2(イソロイシン:0.952g、ロイシン:1.904g、バリン:1.144g)である。
各個体に対して、死亡時、又は試験(実験食供与)開始後56週間後に剖検し、肝線維化抑制効果と肝発癌率と生存率による治療継続効果を検討した。
これらの結果から、コリン欠乏アミノ酸添加食肝線維化・発癌ラットモデルにおいて、ソラフェニブとBCAAを併用投与させることによって、肝線維化抑制効果と肝前癌病変抑制効果が得られる上に、ソラフェニブを単独で投与した場合よりも、生存率と副作用を有意に改善させ、安定して治療継続させることが可能なことが明らかになった。
(細胞増殖抑制作用)
Huh7細胞を6×103cell/wellずつ96well plateに播種し、翌日にLC(FBS10%含)培地に置換し、0,1,2,4,8μMの濃度のソラフェニブにそれぞれ2mMのBCAAを添加して、48時間インキュベーションした。また、BCAAを添加せずに、48時間インキュベーションしたものをコントロールとした。
48時間後に、培地を除去し、4%パラホルムアルデヒドを各wellに添加し15分固定した。パラホルムアルデヒドを除去後、5%ヘキスト溶液を各wellに添加し、1分放置した。5%ヘキスト溶液を除去後、PBS溶液200μlを各wellに添加した。
そのプレートをアレイスキャンにて細胞数を解析し、コントロール(LC10%)を100とした時にそれぞれの群における細胞数を% of proliferationとして算出した。結果を図2に示す。
図2から明らかなように、ソラフェニブ+BCAA群では、特に、ソラフェニブの濃度が2、4、8μM刺激におけるBCAA併用刺激において、ソラフェニブ単独刺激に比較して、有意な細胞増殖抑制作用が見られた。
(抗腫瘍作用増強効果)
Huh7細胞を1x107cell/mouseにてBALB/cヌードマウスの皮下へ移植した。
1週間後、腫瘍径にて群分けをし、5mg/kg sorafenib経口投与±3%BCAA含餌供与を2週間(sorafenib 5日間投与/週)実施した。
3週目投与はsorafenib投与量を5mg/kgから、30mg/kgに増量して5日間経口投与した。その間、3%BCAA含餌の供与は継続した。
投与開始から3週間後の各群の腫瘍径を測定し、腫瘍体積の平均値+SEを算出した。腫瘍体積は腫瘍の長径/2x(短径)2により算出した。
結果を図3に示す。
図3の結果から、明らかなように、ソラフェニブ+BCAA群では、コントロール群投与に比較して、腫瘍体積の縮小の程度が大きく、2剤併用による抗腫瘍効果増強効果の傾向が見られた。
ソラフェニブ単独群、BCAA単独群では、コントロール群と比較して、腫瘍体積の縮小の程度は変わらなかった。
