Main objective

Scope: Therapy

In a clinical prospective Phase I/II study, the effectiveness of vinorelbine and cisplatin, previously shown to be effective, is tested in the most effective sequence and in a clinically relevant situation (i.e., after modern androgen deprivation therapy and standard chemotherapy with taxanes, such as docetaxel and cabazitaxel) in patients with castration-resistant and taxane-resistant prostate cancer who have no other treatment options available. In addition to chemotherapy, the study tests the effectiveness of PSMA-PET/CT guided stereotactic radiation therapy for oligometastatic disease in improving tumor treatment effectiveness and evaluates the safety profile of the combination.
