A Phase 1 Safety, Tolerability, Biodistribution, Dosimetry and Efficacy Study of 177Lu-DOTA-TLX591 With Best Standard of Care in Patients With PSMA Expressing Metastatic Castration-resistant Prostate Cancer

Description:

This is a Phase 1 trial of TLX591, a monoclonal antibody HuX591 conjugated with a DOTA chelator and radiolabelled with 177Lu (177Lu-DOTA-TLX591). TLX591 is being developed as a PSMA-targeting antibody to be radiolabelled with a therapeutic radiosotope for the treatment of PSMA-expressing tumours, therefore this study has been designed to assess the safety and tolerability, pharmacokinetics, whole body biodistribution and radiation dosimetry of 177Lu-DOTA-TLX591.
