Abstract
Description
本出願は、35U.S.C.119(e)に基づいて2020年10月1日に出願された米国仮出願第63/086,593の優先権を主張し、それらの開示全体は、参照により本明細書に組み込まれる。
パンデミックが続く中、変異と選択により、ACE2に対するより高い結合親和性を獲得してウイルス伝播速度が向上するようにSARS-CoV-2ウイルスの進化が促進され、その結果、新たに出現した感染力の強いδバリアントを含む変異株が生じる。実際、αバリアントとδバリアントはどちらも元のSARS-CoV-2ウイルスよりも感染力が高い。SARS-CoV-2バリアントの蔓延は、治療法と予防法を開発する上でまだ解決されていない課題である。SI-F019は中和剤の候補であるが、FDAは患者の治療用にb)バムラニビマブ(Eli Lilly's LY-CoV555;SI-69C4,配列番号29及び30)、c)カシリビマブ(Regeneron's REGN10933;SI-69C5,配列番号31及び32)、d)エテセエビマブ(Eli Lilly's CB-6;SI-69C6,配列番号33及び34);e)イムデビマブ(Regeneron's REGN10987;SI-69C7,配列番号35及び36);f)シルガビマブ(AstraZeneca's AZD1061;SI-69C8,配列番号37及び38)、及びg)チサゲビマブ(AstraZeneca's AZD8895;SI-69C9,配列番号39及び40)を含むいくつかの中和抗体を承認している。
上記の結合親和性アッセイは、抗ヒトIgG Fcキャプチャーバイオセンサーチップ(AHC)表面に固定化されたSI-F019と溶液中のSARS-CoV-2 RBDタンパク質バリアントの結合を測定する一方、アビディティアッセイは、ストレプトアビジンバイオセンサーチップ表面に固定化されたビオチン化SARS-CoV-2 RBDタンパク質バリアントと溶液中のSI-F019の結合を測定する。
中和抗体に対するSI-F019の比較優位性を証明するために、結合応答又は応答の値を使用した。応答は、図15、16に示すように干渉パターンにおけるnmシフトとして測定され、バイオセンサーの表面に結合した分子の数に比例する。応答は、最大濃度の分析物と会合したときに達成される最大結合シグナルであり、動力学結合パラメータ、タンパク質のサイズ、アッセイ条件に依存する複雑な機能であり、相互作用するタンパク質のサイズとフォーマットが類似している限り、特定のアッセイで同等であるべきである。応答の違いは、タンパク質間相互作用の効果的な強度の違いを示すことができ、高い応答は相互作用が強いことを示し、低い応答は相互作用が弱いことを示す。
ウイルス感染を防ぐSI-F019の能力を試験するために、ルシフェラーゼレポーターアッセイによりウイルス感染力を評価した。ルシフェラーゼレポーター遺伝子を含むSARS-CoV-2 Sタンパク質パッケージシュードウイルス(NICPBP)(野生型又は変異株、Sino Biological)を、ACE2を過剰発現する293T細胞(クローン3D4)及びSI-F019の1:3連続希釈物(30μg/mlから)と共インキュベートした。トランスフェクションされた細胞上のACE2の発現は、酵素アッセイ及びFACSアッセイによって確認された。シュードウイルスは、ACE2に結合するSタンパク質を介してACE2陽性細胞に侵入することができ、これによって、ルシフェラーゼの発現が引き起こされる。したがって、発光はウイルスの感染力の読み取りとして使用される。
現在、3つの抗SARS-CoV-2モノクローナル抗体製品は、入院していない患者の軽度から中等度のCOVID-19の治療のために食品医薬品局(FDA)から緊急使用許可(EUA)を取得している。これらの患者は、検査でSARS-CoV-2感染が確認されかつ重症化や入院に進行するリスクが高い患者である。第一、バムラニビマブ+エテセエビマブは、SARS-CoV-2のスパイクタンパク質RBDにおける異なるが重複するエピトープに結合する中和モノクローナル抗体である。第二、カシリビマブ+イムデビマブは、SARS-CoV-2のスパイクタンパク質RBDにおける重複しないエピトープに結合する組換えヒトモノクローナル抗体である。第三、ソトロビマブは、2003年にSARS-CoV生存者から最初に同定されたモノクローナル抗体である。それは、SARS-CoVとSARS-CoV-2の間で保存されているスパイクタンパク質のRBDにおけるエピトープを標的とする。
SI-F019は野生型RBDと比較してRBDの変異型に対して高い親和性で結合し、その主な原因は解離速度が遅いことによるものである。一方、少なくとも3つの中和抗体は少なくとも1つの変異型への結合を失った(N.D.)。
これらの抗体のうち4つは少なくとも1つのバリアントに対して低応答から無応答の範囲であったのに対し、SI-F019はすべてのバリアントに対して増加した応答を示した。
抗体は低応答から無応答の範囲であったのに対し、SI-F019は大きな変化を示さなかった。
より低いIC50値に基づいて、Sタンパク質の変異型を含むシュードウイルスのSI-F019阻害は、野生型Sタンパク質を含むシュードウイルスの阻害よりも強力である。
