Paolo Tarantino: ADC stability does not equal ADC tolerability

Paolo Tarantino shared a post by Raffaele Colombo, on X, adding:

”Antibody-drug conjugate (ADC) stability does not equal ADC tolerability.

In medio stat virtus.”

Raffaele Colombo shared a post on X, about recent paper published in npj Precision Oncology:

First-in-human study of DP303c, a HER2-targeted antibody-drug conjugate in patients with HER2 positive solid tumors.

Authors: Jian Zhang, Yiqun Du, Yanchun Meng, Xiaojun Liu, Yuxin Mu, Yunpeng Liu, Yehui Shi, Jufeng Wang, Aimin Zang, Shanzhi Gu, Tianshu Liu, Huan Zhou, Hongqian Guo, Silong Xiang, Xialu Zhang, Suqiong Wu, Huanhuan Qi, Mengke Li and Xichun Hu.

Trastuzumab envedotin (DP303c): site-specific conjugation, stable linker, drug-to-antibody ratio of 2 with monomethyl auristatin E, 3 milligrams per kilogram.

89 out of 94 patients experienced ocular adverse events.

In contrast…

Trastuzumab vedotin (MRG002): classic conjugation, less stable drug-to-antibody ratio of 4 with monomethyl auristatin E, 2.6 milligrams per kilogram, no ocular toxicity.”
