Description
本出願は、参照によりその全体が本明細書に援用される2015年4月2日に出願された米国仮出願第62/142,257号の利益を主張するものである。
「ペプチド」、「ポリペプチド」および「タンパク質」という用語はそれぞれペプチド結合によって相互に結合した2個以上のアミノ酸残基を含む分子を指す。これらの用語は、例えば、あるタンパク質配列の天然タンパク質と人工タンパク質、タンパク質断片およびポリペプチド類似体(改変タンパク質、変異体、および融合タンパク質等)ならびに翻訳後に改変されたか、または他の場合では共有結合または非共有結合によって改変されたタンパク質を包含する。ペプチド、ポリペプチド、またはタンパク質は単量体でも多量体でもあり得る。ある特定の実施形態において、「ペプチド」、「ポリペプチド」、および「タンパク質」はペプチド結合を介して連結しているα炭素を有するアミノ酸鎖である。したがって、その鎖の一方の末端(アミノ末端)の末端アミノ酸は遊離アミノ基を有し、その鎖の他方の末端(カルボキシ末端)の末端アミノ酸は遊離カルボキシル基を有する。本明細書において使用される場合、「アミノ末端」(N末端と略される)という用語はペプチドのアミノ末端のアミノ酸上の遊離α−アミノ基、またはそのペプチド内の他のいずれかの位置にあるアミノ酸のα−アミノ基(ペプチド結合に関与しているときはイミノ基)を指す。同様に、「カルボキシ末端」という用語はペプチドのカルボキシ末端上の遊離カルボキシル基、またはそのペプチド内の他のいずれかの位置にあるアミノ酸のカルボキシル基を指す。ペプチドにはまた、アミド結合と対照的にエーテル結合によって結合したアミノ酸などのペプチド模倣物を含むがこれらに限定されないあらゆるポリアミノ酸が基本的に含まれる。
アラニン(A)、セリン(S)、およびトレオニン(T)
アスパラギン酸(D)およびグルタミン酸(E)
アスパラギン(N)およびグルタミン(Q)
アルギニン(R)およびリシン(K)
イソロイシン(I)、ロイシン(L)、メチオニン(M)、およびバリン(V)
フェニルアラニン(F)、チロシン(Y)、およびトリプトファン(W)
肥満症は、健康に悪影響を及ぼし得る程に過剰な体脂肪が肝臓を含む複数の組織に蓄積した、医学的状態である。典型的には肥満度指数(BMI)(ある人間の体重をその人間の身長の二乗で割ることにより得られる測定値)が30kg/m2以上と定義され、肥満症の有病率は合衆国および他の多くの先進国において過去10年で著しく増加し、世界的な公衆衛生上の懸念となった。
非アルコール性脂肪性肝疾患(NAFLD)は西洋人種に高度に蔓延している。最近の研究では、この疾患は、肥満個体においては70%の頻度で、痩せた個体においては35%の頻度で、発生し得ると示唆されている(Wanless IR, et al., Hepatology, 12:1106-1110, 1990)。NAFLDは、アルコールをほとんど消費しない個人に生じる肝臓の大滴性脂肪症を特徴とする。NAFLDの組織学的スペクトルは、単なる脂肪症単独、または非アルコール性脂肪性肝炎(NASH)に分類される。いくつかの疫学的研究は飽和脂肪をより多く含む食事を関連付けている(Musso G, et al., Hepatology, 37:909-916, 2003)。しかしNAFLDは、特に甘味飲料からの、フルクトースの摂取とも強く関連している(Ouyang X, et al., J Hepatol., 48:993-999, 2008)。古典的な西洋食は飽和脂肪および糖の両方を多く含む。

別の態様では本開示は1種類以上の薬学的に許容可能な担体と共に本明細書に記載される単離アンタゴニスト性抗原結合タンパク質を含む医薬組成物を提供する。本明細書に記載されるそれらの医薬組成物および使用方法は、下で詳細に説明されるように他の活性薬剤との併用(共投与)実施形態も包含する。
グルカゴン受容体とのそれらの相互作用により、本アンタゴニスト性抗原結合タンパク質は、現在の治療に関連する望まれない副作用のうちの一つまたは複数を低減および/または排除しつつ、糖新生およびグリコーゲン溶解を制御することにより血糖値を低下させるのに、並びにまた、グルカゴンのその受容体との相互作用の遮断が有益である広範囲の状態および障害を治療するのに、有用である。
本実施例では、様々なDIOマウスモデルにおけるグルコース生産の制御と肥満の発達との間の関係を評価する。具体的には、配列番号8に記載の重鎖配列および配列番号9に記載の軽鎖配列を含む抗GCGR抗体(「REMD2.59C」)のインビボ活性を、野生型C57BL/6マウスを用いた20週齢DIOマウスモデルにおいて評価する。野生型C57BL/6マウスは、高脂肪食(「HFD」)を給餌された場合に体脂肪量増加、高血糖症、および高インスリン血症を示すことから、肥満症研究に一般に使用される(REbuffe-Scrive, M et al., Metabolism, 42:1405-1409, 1993; Surwit, RS., Metabolism 44:645-651, 1995)。
i)空腹時血糖測定を、尾静脈から、週1回、Accu−Chek Aviva System(登録商標)を用いて測定した(マウスは試験および空腹時血糖値の前に6時間絶食させる);
ii)経口グルコース負荷試験(OGTT)を試験の最後に全ての動物に実施して、REMD Ab2.59の反復投与効果を試験した。ベースライン(0時点)のグルコースレベルを、16時間時間の絶食後に、グルコースチャレンジに先立って、測定した。2g/kgのグルコースを経口投与した後、Accu−Chek Performa Systemを用いて様々な時点(30、60、120分)の血糖値を測定した;
iii)血清中の脂質プロファイルおよび血液生化学パラメーター(ALT、AST、GGT、ALP、TGおよびTCHO)を、試験全体を通じて検査した。血液試料は、8、12、16および20週目に採取し、即座に4℃、4000g、15分間の遠心分離により処理し、その後、新しい試験管に移した。TOSHIBA TBA−40FR自動生化学分析装置を用いて、脂質プロファイルおよび血液生化学パラメーターを測定した;
iv)脂質プロファイル(TG、TCHO、HDL−CおよびLDL−C)をプロトコルに従って動物の肝臓から抽出した後、TOSHIBA TBA−40FR自動生化学分析装置を用いて、脂質プロファイルを測定した;
v)全試験動物のインスリンレベルを8、12、16および20週目に測定した。GLP−1およびレプチンを試験の最後にELISA法を用いて測定した。血清を分析に使用した;
vi)終了日に、OGTT試験後に剖検を行った。試験の最後に、組織または臓器を採取し、膵臓、白色脂肪組織(WAT)、筋肉(腓腹筋)および肝臓の湿重量を測定した。これらの組織試料の半分をH&E(肝臓およびWAT)またはIHC(膵臓)分析用に固定およびパラフィンブロック包埋した。視床下部、脳、心臓および膵臓、WAT、筋肉、肝臓の残り部分は、−80℃で保存するか、さらなる分析にかけた。上記の様々な測定および/または分析は、下記の追加の材料および方法セクションに記載の通りに行う。全ての統計検定を行い、有意水準は5%、すなわちP<0.05に設定した。試験設計の通りに、全ての測定パラメーターについて、群の平均および標準偏差を算出した。群間には、GraphPad Prism 5.0ソフトウェアによる1元配置分散分析(ANOVA)を用いた。
体重および摂食量:図1に示されるように、REMD2.59群は9週目から20週目まで体重増加を効率的に減少させた。REMD2.59群のものと同量の一日食を9週目から20週目まで与えられたペアフィード群は、REMD2.59群と比べて、同様の、しかしわずかに多い、体重増加を示した。この知見は、REMD2.59の効果が食物摂取の減少に限定されないことを示唆する。1週目から20週目までHFDと同時にREMD2.59の毎週注射を与えられた防止群は、HFDの摂取にもかかわらず、他の全ての群と比較して最も少ない体重増加を示した。具体的には、防止群の平均体重(35.3±3.0g)は、試験の終わり(140日目、すなわち20週目の終わり)に、ビヒクル群(53.3±2.4g)よりも34%低く(P<0.01)、さらには通常食群(38.6±3.1g)よりも9%低かった。図2に示されるように、防止群は、グラム体重当たり、通常食群と同量のカロリーを消費した。一方、HFD給餌群(ビヒクル群、REMD2.59群およびペアフィード群)は全て、グラム体重で調整された場合、ほぼ同量のカロリーを消費した。それでもなお、体重差を考慮に入れて、ビヒクル群は最大の平均体重を有するために、REMD2.59群およびペアフィード群と比較して、ビヒクル群は動物当たりより多量のカロリーを消費する。
実施例1で示されたREMD2.59C処置の有意な効果を考慮して、様々なマウスモデルにおけるグルコース生産の制御とNAFLD/NASHの発達との関係を評価する。本実施例では、REMD2.59Cのインビボ活性を、NASH派生HCCマウスモデル(STAM(登録商標)モデル、Fujii et al, Med Mol Morphol, 46:141-152, 2013)において評価する。STAM(登録商標)モデルでは、C57BL/6Jマウスに、生後2日目に200μgのSTZの単回皮下注射を注入し、4週齢の後にHFDまたは固形飼料を給餌する。雄マウスにおいて、この併用STZ−HFD処置は、HFD給餌の1週間後に脂肪症および糖尿病の発達をもたらし、HFDの継続により、雄マウスは高血糖症および中等度の高脂血症と一緒に線維症、肝硬変および肝細胞癌(HCC)を発達させ、故に、ヒトNASHとよく似ている。STZのみで処置された雄マウスおよびSTZ−HFDで処置された雌マウスは糖尿病を発症するが、HCCは発達させない。
実施例1で示されたREMD2.59C処置の有意な効果を考慮して、REMD2.59Cのインビボ活性をdb/dbマウスを用いるNASHのマウスモデルにおいて評価する。本研究は24週間の研究となる。追加で48週間の研究を行う場合もある。C57BL/6バックグラウンドのdb/dbマウスをジャクソン研究所(バーハーバー、メーン州)から購入する。db/dbマウスは高レプチン血症、肥満および糖尿病のマウスである。メチオニンおよびコリン欠乏(MCD)食を給餌されたdb/dbマウスは脂肪肝を自然に発症し、脂肪肝はNASHへと進行する(Wortham et al., Dig Dis Sci., 53(10): 2761-2774、2008年10月)。各6匹の10〜12週齢db/dbマウスに、メチオニンおよびコリンを欠乏した食餌(MCD)(MPバイオメディカルズ社(MP Biomedicals)、オハイオ州ソロン、カタログ番号960439)もしくはメチオニンおよびコリンを添加した同一食餌(MCDS)(MPバイオメディカルズ社、カタログ番号960441)を4週間、または、HFD+フルクトース西洋食(WD)(#58Y1、テストダイエット社(TestDiet)、ミズーリ州セントルイス)、もしくは固形飼料(対照食)(#58Y2、テストダイエット社、ミズーリ州セントルイス)を24週間、自由給餌する。マウスは、22℃、12時間/12時間の明暗サイクルで、鋼鉄製マイクロアイソレーターケージ内に個々に収容する。全手順を、実験動物の管理と使用に関するアメリカ国立衛生研究所(NIH)ガイドラインに従って実施した。マウスに、毎週または隔週で、皮下注射により、ビヒクル(10mM 酢酸ナトリウム、5%ソルビトール、および0.004%ポリソルベート20)、2.5mg/kg REMD2.59C抗体(「低用量」)、または5mg/kg REMD2.59C抗体(「高用量」)を、必要に応じて4週間または24週間投与する。投与する用量は10mg/kg/月を超過しないものとする。
本実施例は、NASHと診断された対象における完全ヒト抗GCGR抗体を用いた週1回処置の安全性、薬物動態および薬力学的効果を評価するための、無作為化、二重盲検、プラセボ対照、並行群間、多用量研究について記述する。処置は、処置の有効性および安全性を観察および定量化するのに十分な長さの、最長6または12ヵ月継続し得る。
体重:全動物の体重を種々の研究の期間全体を通じて毎週測定する。
