新規卵巣がん治療薬オラパリブ

米食品醫薬品局(FDA)は12月19日、英アストラゼネカ(AZ)のPARP(ポリADP-リボース合成酵素)阻害剤Lynparza(オラパリ ブ)をBRCA遺伝子変異陽性の進行卵巣がんの適応で承認した。また、併せて、同剤のコンパニオン?ダイアグノスティクスである BRACAnalysisCDxも承認した。オラパリブの適応は、BRCA遺伝子欠損のある前治療歴を持つ進行卵巣がんである。BRCA遺伝子は、損傷さ れたDNAの修復に関與し、通常、腫瘍の成長を抑制する。BRCA遺伝子欠損をもたらす同遺伝子変異の女性は卵巣がんになりやすく、卵巣がん患者の全體の 10%-15%は遺伝性のBRCA変異に関與しているとみられる。

阿斯利康卵巢癌藥物Lynparza(奧拉帕尼,olaparib)

Lynparza(olaparib)是一種首創口服多聚ADP核糖聚合酶(PARP)抑制劑,利用DNA修復途徑的缺陷,優先殺死癌細胞。目前,阿斯利康正開展多個III期研究,調查olaparib用于BRCA突變卵巢癌、胃癌、乳腺癌的治療。
