Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of the study is to assess and evaluate dosimetry, safety, and tolerability following administration of up to 12 cycles of (177Lu) vipivotide tetraxetan (also referred to as \[177Lu\]Lu-PSMA-617 or 177Lu-PSMA-617 and hereafter identified as AAA617) in taxane-naïve adult participants with PSMA-positive mCRPC who progressed on a prior ARPI treatment with normal renal function or mild renal impairment (eGFR ≥ 60ml/min).
