抗體藥物偶聯(lián)物(ADC)是通過偶聯(lián)臂將抗體和小分子藥物相結(jié)合,可殺死或抑制癌細(xì)胞等特定細(xì)胞的抗體藥物。到2021年10月為止,除了美國FDA已經(jīng)批準(zhǔn)上市的12個品種以外,還有3種具有類似結(jié)構(gòu)的免疫毒素偶聯(lián)物(重組)也獲得了批準(zhǔn)。隨著研發(fā)的不斷推進(jìn),目前還有約150種ADC藥物正處于臨床試驗階段。
在ADC的純化工藝中常用到的分離方法,一種是在抗體上結(jié)合藥物之后,通過疏水層析(HIC)分離出結(jié)合小分子藥物數(shù)量不同的ADC;另一種是通過尺寸排阻層析(SEC)根據(jù)分子尺寸的差異,分離ADC的多聚體和未反應(yīng)試劑。下表中記載了已獲批的ADC藥物與免疫毒素偶聯(lián)藥物的純化工藝,以及可使用的TOYOPEARL®和羥基磷灰石填料。另外,使用HIC分離ADC的相關(guān)內(nèi)容,在技術(shù)資料(TOYOPEARL制備填料)No.6和No. 11中也有所介紹。
