Description
本出願は、あらゆる目的のために参照により本明細書に組み込まれる、2013年3月15日に出願された米国特許出願第61/793,133号の優先権を主張する。
本発明は、癌患者のバイオマーカーを判定及び検出するためのアッセイ、並びに治療方法に関する。
いくつかの上記で同定されたARスプライス変異体(ARV1、ARV3/V7、ARV567及びARV8など)、AR体細胞突然変異(L701H、V715M、H874Y及びT877Aなど)の存在を評価するために、TMPRSS2融合遺伝子であるTMPRSS2:ERG及びTMPRSS2:ETV1とともに、2つの独立した前立腺癌FFPET試料試験でTaqMan qRT−PCRアッセイを行った。第1試料セットは、II期〜IV期の範囲の42個の前立腺癌から構成される。ARV1及びARV3/V7は、全試料のうちの92%が一方又は両方の変異体の発現を示す最も一般的な変異体であるという結果が示された。TMPRSS2:ERGは、試験した全試料のうちの72%に存在し、AR変異体発現との一致率が高く、後期(III/IV)前立腺癌試料において一般的であった。第2試料セットは、一致する隣接した正常なFFPETを含む8個の前立腺癌から構成される。腫瘍試料及び一致する正常な試料の両方においてAR変異体の同様の発現が観察されたが、前立腺腫瘍試料は、一致する正常な試料(33%)よりもTMPRSS2:ERG融合遺伝子において高く、より一般的な発現(66.67%)を示した。4個のAR変異体は、いずれの試料セットにおいても検出されなかった。
TaqMan qRT−PCR 213を使用して、女性乳癌FFPET試料、80ER−PR−Her2−試料、68ER−PR−Her2+試料、及び64ER+PR+Her2−試料、並びにESR1、CYP17、CYP19、完全長AR並びにARスプライス変異体ARV1、ARV3/V7、ARV567、及びデルタ3ARの存在用の8個の乳癌細胞系を試験した。ARV3/V7及びデルタ3ARは、ER+PR+Her2−及びER−PR−Her2+試料セットにおいて最も一般的な変異体であり、85%を超えるこれらの試料は、これらの変異体の一方若しくは両方の発現を示した。一方、ARV1、ARV3/V7、及びARV567は、ER−PR−Her2−試料セットにおいて最も一般的な変異体であり、90%を超えるこれらの試料は、これらのうちの1つ又は組み合わせの発現を示した。高級グレードのER+PR+Her2−及びER−PR−Her2+試料は、低級グレード試料と比較して、ほとんどの変異体において低発現値であることが観察された。CYP19は、全ての試料セットにおいて非常に一般的であり、全試料のうちの75%を超えるものが発現を示し、CYP17の発現は、試験した全試料のうちの30%未満で観察された。
以下に、本願の当初の特許請求の範囲に記載された発明を付記する。
[1] 患者を治療する方法であって、
a.患者から生体試料を得る工程と、
b.前記生体試料を複数のバイオマーカーにおいて試験する工程と、
c.前記バイオマーカーの存在、非存在又は量に基づいて、前記患者に治療を施す工程と、を含む、方法。
[2] 前記バイオマーカーが、完全長アンドロゲン受容体(AR);AR変異体1(ARV1)、AR変異体3/変異体7(ARV3/V7)、AR変異体567(ARV567)、AR変異体8(ARV8)、TMPRSS2完全長野生型;ERG完全長野生型;ETV1完全長野生型;TMPRSS2:ETV1融合遺伝子(TMP:ETV);及びTMPRSS2融合遺伝子(TMP:ERG);CYP17;CYP11;HSD3B1;AKRIC3;NPY;PSA;KLK2;AGR2;BST1;PTPRC;ESR1;Her2;エストロゲン受容体(ER);PR;CYP19;Delta3AR;L701H、H974Y、T877A及びV715M、からなる群から選択される、請求項1に記載の方法。
