Unmodified vinblastine (VLB) targeted through one of the antigen combining sites of the hybrid-hybrid 28.19.8 monoclonal is potentially more effective in suppressing the growth of established MAWI tumour xenografts implanted on nude mice than free VLB in the absence of the targeting agent, presumably due to an increased local drug concentration. Our efficacy results in this study suggest that drug, specifically removed from the circulation by hybrid-hybrid antibody previously located to the tumour mass, can be made available in a pharmacologically active from. Histological analysis of the treated tumours revealed dramatic changes in the tumour organisation with only a few surviving tumour cells with altered morphology.
通过双杂交28.19.8单克隆抗体的一个抗原结合位点靶向的未修饰长春碱(VLB),在抑制植入裸鼠体内的已建立的MAWI肿瘤异种移植物生长方面,可能比没有靶向剂时的游离VLB更有效,这可能是由于局部药物浓度增加。我们在本研究中的疗效结果表明,通过先前定位于肿瘤块的双杂交抗体从循环中特异性去除的药物,可以以药理活性形式提供。对治疗后肿瘤的组织学分析显示肿瘤组织发生了显著变化,只有少数存活的肿瘤细胞形态发生了改变。
