In the present disclosure, polymer conjugates, including polymer-antibody-drug conjugates (polymer ADCs) are described, as well as the use of such conjugates to treat human disease. The polymer conjugates can contain a large number of polymer-bound agents, thus effectively increasing the drug antibody ration (DAR) of the antibody significantly beyond the currently available technology. This may be of particular importance when antibodies to low density antigens are used as target antibodies. The described polymer-ADCs have improved pharmacokinetics and solubility relative to traditional ADCs. The linker between agent and the polymer can be tailored to provide release of toxin at the desired site and under the desired conditions within the tumor. An additional feature of the polymer-ADCs of the current disclosure is that a purification moiety can be attached to the polymer backbone to provide ease of purification of the polymer-ADCs.
本公开说明书描述了高分子共轭物,包括高分子-抗体-药物共轭物(高分子ADC),以及使用这些共轭物治疗人类疾病。高分子共轭物可以包含大量高分子结合的药物,从而有效地将抗体的药物比例(DAR)显著提高到目前可用技术之外。当用于低密度抗原的抗体时,这可能特别重要。所述的高分子ADC相对于传统ADC具有改进的药代动力学和溶解度。代理和高分子之间的连接剂可以定制以在肿瘤内所需的位置和条件下释放毒素。本公开说明书的高分子ADC的另一个特点是可以将净化基团附加到高分子骨架上,以提供高分子ADC的易于纯化性。
