There is disclosed an improved ADC (antibody drug conjugate) type composition having at least two different drug payloads conjugated to a single targeting protein. More specifically, the present disclosure attaches a first drug conjugate to a dual Cysteine residue on a targeting protein and a second drug conjugate with a different drug to a Lys residue on the targeting protein.
本发明公开了一种改进的 ADC(
抗体药物共轭物)型组合物,该组合物至少有两种不同的药物有效载荷与单个靶向蛋白共轭。 更具体地说,本公开将第一种药物共轭物连接到靶向蛋白上的双半胱
氨酸残基上,将第二种不同药物共轭物连接到靶向蛋白上的赖
氨酸残基上。
