Avelumab in Men With Metastatic Castration-Resistant Prostate Cancer, Enriched for Patients Treated Previously With a Therapeutic Cancer Vaccine.
Journal of Immunotherapy 2023 May 2
Therapeutic cancer vaccines including sipuleucel- T , a prostatic acid phosphatase (PAP) targeted vaccine that improves survival in metastatic castration-resistant prostate cancer (mCRPC), can produce immune responses that translate to clinical benefit. The effects of sequential checkpoint inhibitors after therapeutic vaccine on immune responses are unknown. Avelumab is an anti-programmed death ligand-1 monoclonal antibody evaluated in patients with mCRPC in the JAVELIN solid tumor phase 1 trial expansion cohort, enriched for patients with a previous therapeutic prostate cancer-targeted vaccine. mCRPC patients received intravenous avelumab 10 mg/kg every 2 weeks with imaging every 6 weeks. Peripheral blood T-cell responses to PAP and to PA2024, the peptide containing PAP utilized by the vaccine, were evaluated pre and posttreatment. Eighteen patients enrolled, and previous treatments included abiraterone or enzalutamide in 14 (78%), therapeutic cancer vaccine in 14 (78%), and chemotherapy in 4 (22%). Avelumab had a manageable safety profile. There were no sustained prostate specific antigen decreases. Of 17 patients evaluable for best overall response by RECISTv1.1, 12 had stable disease (SD) and 5 had progressive disease. Seven patients had SD for >24 weeks posttreatment. Fourteen patients had previously received therapeutic cancer vaccines. Eleven (79%) had SD as the best overall response. Of these 14 patients, 9 had previously received sipuleucel T . Analysis of antigen-specific T-cell responses pre and postavelumab treatment did not demonstrate changes in interferon-γ production or proliferation in response to PAP or PA2024. This unplanned analysis does not support the use of sequential therapeutic cancer vaccine therapy followed by programmed death ligand-1 inhibition in mCRPC.
