A Phase I/II, Safety Clinical Trial of DCVAC/PCa and ONCOS-102 in Men With Metastatic Castration-resistant Prostate Cancer
Study Details
Study Description
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.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: DCVac and ONCOS-102 ONCOS-102 is given intra-tumor up to 4 times, cyclophosphamide is given prior to the first dose of ONCOS-102 and at the fifth week of treatment DCVac is given sc every 21-28 days for up to 10 doses |
Biological: DCVac/PCa
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.
Other Names:
Drug: Cyclophosphamide
immunomodulatory medication given around the ONCOS-102 dosing

Outcome Measures
Primary Outcome Measures
- Progression Free Survival [96 months]
PFS measured by modifications to the RECIST 1.1. PFS is defined as the time from the first dose of SoC therapy administered to tumor progression or death from any cause.
Secondary Outcome Measures
- Overall Survival [96 months]
Defined as the time from Baseline visit to the date of death for any cause
- Safety [96 months]
Reports of adverse events, serious adverse events, lab abnormalities utilizing NCI CTCAE v.4.033
- Time to Progression-PSA [96 months]
demonstrated by rising PSA as defined by the Prostate Cancer Workging Group2
- Radiographic Progression- free survival [96 months]
composite assessment of progression of bone lesions, soft-tissue lesions or death due to any cause
