References |
Sipuleucel-T (Provenge) |
An autologous dendritic cell-based vaccine that targets prostate-specific antigen (PSA) and prostatic acid phosphatise (PAP). |
Approved by FDA for metastatic castration-resistant prostate cancer (mCRPC). Shown to improve overall survival. Ongoing studies explore combination therapies. |
[9,10] |
Prostvac-VF |
A viral vector-based vaccine using modified vaccinia Ankara (MVA) and fowlpox vectors expressing PSA and costimulatory molecules. |
In clinical trials, it has shown promise in extending overall survival. Investigated for use in combination with other therapies. |
[11-13] |
PSA-TRICOM |
A vaccine that combines PSA with a triad of costimulatory molecules (TRICOM) to enhance T-cell activation. |
Clinical trials have shown mixed results, with some evidence of prolonged survival. Research continues optimizing efficacy. |
[14] |
GVAX |
A vaccine that uses genetically modified prostate cancer cells to secrete GM-CSF, a cytokine that stimulates immune responses. |
Ongoing clinical trials to assess its efficacy and safety. Shown to induce immune responses against prostate cancer in earlier studies. |
[15,16] |
PSA-TRICOM + Ipilimumab |
Combines PSA-TRICOM with ipilimumab, a CTLA-4 inhibitor, to enhance immune response through checkpoint blockade. |
Trials are investigating the combined approach for improved efficacy in advanced prostate cancer. Initial results are promising. |
