Brief summary
This clinical trial is to evaluate the safety of the combination of DCVAC/PCa with ONCOS-102 in men with castration-resistant advanced metastatic prostate cancer, who have progressed following initial therapy with either hormones (e.g. abiraterone and enzalutamide) or chemotherapy. Male patients with castration-resistant advanced metastatic prostate cancer, who have progressed following initial therapy with either All patients must have at least one readily accessible soft tissue/nodal tumor lesion (for intra-tumoral application of ONCOS-102 and biopsy.
Detailed description
Study Description: * All patients who fulfill all eligibility criteria will undergo a leukapheresis procedure. * ONCOS-102 administration will start within 3 weeks of leukapheresis at Week 5 (35 days since baseline +/- 2 days), and 3 further doses will be administered on a weekly basis * Cyclophosphamide A priming bolus dose of CPO (300 mg/m2 intravenously) will be given 1-3 days before the first (Week 5) and the fifth (Week 14) of ONCOS-102 administration. * DCVAC/PCa therapy will start 6 weeks after leukapheresis at Week 8. DCVAC/PCa will be administered subcutaneously in cycles, always on Day 1 (+/- 3 days) of the corresponding cycle.
Interventions
Oncolytic adenovirus containing immunostimulatory cytokine granulocyte-monocyte colony-stimulating factor (GM-CSF). This is an experimental therapy. DCVac/Pca consists of activated autologous dendritic cells. This is an experimental therapy.

Exclusion criteria
* Patients with neuroendocrine or small cell cancer of the prostate 2. History of other malignant disease (with the exception of the primary prostate cancer and non-melanoma skin tumors) in the past 5 years Pre-defined co-morbidities * Administration of experimental therapy within the last 4 weeks before start of screening * Treatment with immunotherapy within the last 3 months before start of screening * Treatment with radiopharmaceutical drugs within 8 weeks before start of screening * Receipt of oncolytic virus treatment or vaccination with a live virus within 4 weeks of study start * History of organ transplantation
