Randomized Controlled TrialA phase I study of enfortumab vedotin in Japanese patients with locally advanced or metastatic urothelial carcinoma.
Locally advanced or metastatic urothelial cancer is an aggressive form of cancer with high recurrence rates and low survival. Nectin-4 is a cell adhesion molecule commonly expressed in several tumors, including high expression in urothelial cancer. Enfortumab vedotin is an antibody-drug conjugate composed of an anti-Nectin-4 humanized monoclonal antibody linked to the microtubule disrupting agent, monomethyl auristatin E. ⋯ One patient achieved a confirmed complete response (Arm A) and five achieved confirmed partial responses (n = 3, Arm A; n = 2, Arm B). Objective response and disease control rates were 35.3% and 76.5%, respectively. In Japanese patients with locally advanced/metastatic urothelial cancer, enfortumab vedotin is well tolerated with preliminary antitumor activity and a pharmacokinetic profile consistent with prior reports.
