Detailed Description

This study consists of two parts (Part 1 and 2). Part 1 is the dose escalation portion of the study, which will investigate ascending doses of [225Ac]Ac-AKY-1189 (up to 6 cycles) in patients with locally advanced or metastatic solid tumors. The aim of Part 1 is to determine the maximum tolerated dose (MTD) or maximum administered dose (MAD) and the recommended Phase 2 dose. Part 2 will be the dose expansion portion of the study and will enroll locally advanced or metastatic solid tumor patients who are identified as Nectin-4 positive by [64Cu] Cu-AKY-1189. Part 2 aims to further assess the efficacy of [225Ac]Ac-AKY-1189 at the RP2D in 3 different cohorts of patients.
