関連出願
本願は、2013年1月8日に出願された米国仮出願No.61/750,014の利益を主張する。当該仮出願の内容はそれら全体において出典明示により本明細書に包含させる。
本発明は、一般的には、免疫学および免疫療法の分野、より具体的には免疫調節オリゴヌクレオチド(IRO)組成物、およびトール様受容体(Toll-like Receptor)介在性免疫応答の阻害および/または抑制のためのそれらの使用に関する。特に、本発明は、TLR9、TLR7および/またはTLR8刺激を通して通常生成されるサイトカインをユニークに阻害するトール様受容体9(TLR9)、TLR7および/またはTLR8のアンタゴニストに関する。
トール様受容体(TLR)は、免疫系の多くの細胞に存在し、自然(innate)免疫応答に関与することが示されている(Hornung, V.ら, (2002) J. Immunol. 168:4531-4537)。脊椎動物または哺乳動物において、このファミリーは、細菌、真菌、寄生生物およびウイルス由来の病原体関連分子パターンを認識することが知られているTLR1〜TLR10と呼ばれる10のタンパク質から成る(Poltorak, a.ら (1998) Science 282:2085-2088; Underhill, D.M.,ら (1999) Nature 401:811-815; Hayashi, F.ら (2001) Nature 410:1099-1103; Zhang, D.ら (2004) Science 303:1522-1526; Meier, A.ら (2003) Cell. Microbiol. 5:561-570; Campos, M.A.ら (2001) J. Immunol. 167: 416-423; Hoebe, K.ら (2003) Nature 424: 743-748; Lund, J. (2003) J. Exp. Med. 198:513-520; Heil, F.ら (2004) Science 303:1526-1529; Diebold, S.S.,ら (2004) Science 303:1529-1531; Hornung, V.ら (2004) J. Immunol. 173:5935-5943)。TLRは、哺乳動物が外来分子を認識してそれに対する免疫応答を開始する重要な手段であり、自然免疫応答と適応免疫応答を関連付ける手段も提供する(Akira, S.ら (2001) Nature Immunol. 2:675-680; Medzhitov, R. (2001) Nature Rev. Immunol. 1:135-145)。TLRは、自己免疫、感染病、および炎症を含む多くの疾患の病因に役割を果たすことも示されており(Cook, D.N.ら (2004) Nature Immunol. 5:975-979)、適当な薬剤を用いるTLR介在性活性化の制御は、疾患介入のための手段を提供しうる。
本発明は、インビトロおよびインビボサイトカインおよびケモカインプロフィールと明確に拮抗し、TLR9、TLR7および/またはTLR8刺激を通して通常生成されるTLR7および/またはTLR9のアンタゴニストを提供する。TLR9、TLR7および/またはTLR8アゴニストに対するサイトカインおよびケモカイン応答とユニークに拮抗する能力は、疾患特異的およびさらに患者特異的に種々の疾患状態を予防および/または処置する能力を提供する。
本発明は、免疫療法適用のための免疫調節剤としてのオリゴヌクレオチドベースの化合物の治療的使用に関する。本発明は、TLR9、TLR7および/またはTLR8との相互作用を通して種々の免疫阻害プロフィールを提供するオリゴヌクレオチドベースの化合物を提供する。具体的には、本発明は、TLR9、TLR7および/またはTLR8介在性免疫応答を阻害および/または抑制するためのトール様受容体9、7および/または8(TLR9、TLR7および/またはTLR8)のアンタゴニストとして免疫調節オリゴヌクレオチド(IRO)化合物を提供する。これらIROは、内因性および/または外因性TLRリガンドまたはアゴニストに応答してTLR9、TLR7および/またはTLR8介在シグナル伝達の阻害または抑制を提供する化学修飾および/またはヌクレオチド間連結を有する。本明細書で引用した参考文献は、当該分野の知識水準を反映し、それら全体において出典明示により本明細書に包含させる。引用した参考文献と本明細書の開示間の対立は後者に有利に解決される。
用語「オリゴヌクレオチド」は、一般的には、複数の連結ヌクレオシド単位を含有するポリヌクレオシドを表す。そのようなオリゴヌクレオチドは、ゲノムまたはcDNAを含む、既存の核酸供給源から得ることができるが、好ましくは合成法により生成される。好ましい態様において、各ヌクレオシド単位は、限定されるものではないが、修飾ヌクレオシド塩基および/または修飾糖単位を含む、野生型のオリゴヌクレオチドと比較して種々の化学修飾および置換を含むことができる。化学的修飾の例は当業者に知られており、例えば、Uhlmann, E.ら (1990) Chem. Rev. 90:543; “Protocols for Oligonucleotides and Analogs” Synthesis and Properties & Synthesis and Analytical Techniques, S. Agrawal, Ed, Humana Press, Totowa, USA 1993;およびHunziker, J.ら (1995) Mod. Syn. Methods 7:331-417;およびCrooke, S.ら (1996) Ann.Rev. Pharm. Tox. 36:107-129に記載されている。ヌクレオシド残基は多くの既知のヌクレオシド間連結のいずれかによって互いに結合させることができる。そのようなヌクレオシド間連結には、限定されるものではないが、ホスホジエステル、ホスホロチオエート、ホスホロジチオエート、アルキルホスホナート、アルキルホスホノチオアート、ホスホトリエステル、ホスホロアミダート、シロキサン、カーボネート、カルボアルコキシ、アセトアミダート、カルバメート、モルホリノ、ボラノ、チオエーテル、架橋ホスホロアミダート、架橋メチレンホスホネート、架橋ホスホロチオエート、およびスルホンヌクレオシド間連結が含まれる。用語「オリゴヌクレオチド」は、1またはそれ以上の立体特異的ヌクレオシド間連結(例えば(RP)−または(SP)−ホスホロチオエート、アルキルホスホナート、またはホスホトリエステル連結)を有するポリヌクレオシドも包含する。本明細書で用いている用語「オリゴヌクレオチド」および「ジヌクレオチド」は、あらゆるヌクレオシド間連結(該連結がリン酸基を含むか含まないかに関わらず)を有するポリヌクレオシドおよびジヌクレオシドを含むことを明確に意図する。ある好ましい態様において、これらのヌクレオシド間連結は、ホスホジエステル、ホスホロチオエート、またはホスホロジチオエート連結、またはそれらの組み合わせでありうる。
免疫調節部分を含むオリゴヌクレオチドの合成
本発明のIRO化合物はすべて標準手順により合成された(例えば米国特許公開公報No.20040097719を参照)。
TLR7およびTLR9刺激のインビボ阻害
C57BL/6マウスの左の脇の下に、0時間に5mg/kgのIRO化合物を、24時間に0.25mg/kgのTLR9アゴニストまたは10mg/kgのTLR7アゴニストをs.c.注射した。血清サンプルを、TLR9またはTLR7アゴニスト注射の2時間後に得、IL−12濃度をELISAで測定した。結果を表3に示す。これらの結果は、本発明のIRO化合物がTLR7および/またはTLR9活性をインビボで阻害することができること、より一般的には、本発明のIRO化合物がTLR活性化を阻害することができることを示す。
TLR7/TLR9インビボアンタゴニスト試験
雌のC57BL/6マウス(2/群)の右脇腹に、0時に、5mg/kgのアンタゴニスト化合物をs.c.注射した。次に、マウスの左脇腹に、24時に、TLR9(0.25mg/kg)またはTLR7(10mg/kg)アゴニストを注射した。アゴニスト投与2時間後に眼窩内出血により血液を収集した。次に、血清サンプル中でサイトカイン/ケモカイン反応をLuminex xMAPシステムを用いる多重分析により評価した。結果を図1および2に示す。
TLR4、7、8および9を発現するHEK293細胞の細胞培養アッセイ
ヒトTLR4/CD14/MD−2またはmTLR9を安定に発現するヒト胚腎臓(HEK)293細胞およびヒトTLR7またはTLR8を安定に発現するHEK293XL細胞はInvivogen (San Diego, CA)から得た。HEK細胞を6時間でレポーター遺伝子(SEAP、Invivogen)で一時的にトランスフェクトした。適当なTLRアゴニストを、種々の濃度のアンタゴニストの存在または非存在下で培養物に加え、培養を18時間続けた。処理の最後に、20mlの培養上清物をそれぞれの処理物から取り、製造業者のプロトコール(Invivogen)にしたがって150mlのQuanti−Blue基質を使用してSEAP活性について試験した。結果をPBS処理細胞に対するNF−κB活性化における倍数変化として計算し、50%抑制濃度(IC50)値を決定した。結果を図3に示す。
