Excerpt

Enfortumab vedotin is a human monoclonal antibody conjugate that is used in the therapy of refractory, locally advanced or metastatic urothelial cancer. Enfortumab vedotin has been linked to transient, mild-to-moderate serum enzyme elevations during therapy but has not been implicated in instances of clinically apparent liver injury with jaundice.
