Gedetailleerde beschrijving
This study consists of two parts.
Part A is a dose escalation study to determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of MRG004A.
Part B is a disease specific multi-cohort dose expansion study to further assess the efficacy and safety of MRG004A at confirmed RP2D.
