To date, anti-CTLA-4 (ipilimumab) or anti-PD-1 (nivolumab) monotherapy has not
been demonstrated to be of substantial clinical benefit in patients with prostate
cancer. To identify additional immune-inhibitory pathways in the prostate-tumor
microenvironment, we evaluated untreated and ipilimumab-treated tumors from
patients in a presurgical clinical trial. Levels of the PD-L1 and VISTA
inhibitory molecules increased on independent subsets of macrophages in treated
tumors. Our data suggest that VISTA represents another compensatory inhibitory
pathway in prostate tumors after ipilimumab therapy.
