tcsc1242 VcMMAE

VcMMAE is a drug-linker conjugate for ADC with potent antitumor activity by using the anti-mitotic agent, monomethyl auristatin E (MMAE), linked via the lysosomally cleavable dipeptide, valine-citrulline (vc).

In Vitro: Monomethyl auristatin E (MMAE) is efficiently released from SGN-35 within CD30⁺ cancer cells and, due to its membrane permeability, is able to exert cytotoxic activity on bystander cells^[1]. MMAE sensitized colorectal and pancreatic cancer cells to IR in a schedule and dose dependent manner correlating with mitotic arrest. Radiosensitization is evidenced by decreased clonogenic survival and increased DNA double strand breaks in irradiated cells^[2].

In Vivo: Monomethyl auristatin E (MMAE) in combination with IR results in tumor growth delay, tumor-targeted ACPP-cRGD-MMAE with IR produces a more robust and significantly prolonged tumor regression in xenograft models^[2].
