The primary aim of the study was to characterize and quantify the histopathological changes in the surgical specimens obtained in patients undergoing prostatectomy in addition to imaging changes (MRI) following a single injection of Liproca Depot in patients with localized prostate cancer.

The primary aim of the study was to characterize and quantify the histopathological changes in the surgical specimens obtained in patients undergoing prostatectomy in addition to imaging changes (MRI) following a single injection of Liproca Depot in patients with localized prostate cancer.

The secondary aims ere to evaluate efficacy and safety of a single injection of Liproca Depot, and to follow the pharmacokinetic profile.
