Cabazitaxel in Combination With 177Lu-PSMA-617 in Metastatic Castration-resistant Prostate Cancer

This prospective, single-centre, single-arm, open label, phase I/II trial will assess the safety, efficacy and anti-tumour activity of cabazitaxel in combination with 177Lu-PSMA-617 in patients with metastatic castration-resistant prostate cancer (mCRPC). This study aims to assess and establish the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), and recommended phase 2 dose (RP2D) of cabazitaxel in combination with 177Lu-PSMA-617 in patients with mCRPC. 32-44 men with mCRPC who have progressed on prior docetaxel and a second-generation AR antagonist will be enrolled in this trial in two stages: dose escalation and a dose expansion phase over a period of 18 months.
