An Efficacy and Safety Study With Licroca Depot, a Controlled Release Product, Injected Into the Prostate — 2-HOF  

Prostate Cancer Clinical Trial

Official title: An Open, Single and Multiple Dose, Efficacy and Safety Proof of Principle Study of Liproca Depot, a Controlled Release Formulation of 2-hydroxyflutamide, Injected Into the Prostate in Patients With Localized Prostate Cancer

Status Completed

Clinical Trial Summary

The primary objective was to evaluate efficacy of a single dose of Liproca Depot in patients with localized prostate cancer. Primary efficacy variable was the proportion of patients showing PSA nadir. 24 Caucasian men, with a mean age at inclusion of 68.4 years, with localized prostate cancer were injected once with a ready made paste including 600 mg 2-hydroxyflutamide (Liproca Depot) into the site of the prostate where the tumour was localized. The patient was monitored for prostate-specific antigen (PSA) for maximum 6 months or to progression within this time period. The primary endpoint showed interesting results with high success rate (83%), i.e. proportion of patients (Responders) that reached plasma PSA nadir.

Clinical Trial Description

Patients with localized prostate cancer were followed to progression or maximum 24 weeks after a single injection in one lobe of 2-8 mL ready-made paste (corresponding to 400-1600 mg 2-Hydroxyflutamid). Progression was defined as an increase in PSA by > 25% over baseline or on-treatment nadir.Among the 24 patients the primary endpoint, plasma PSA nadir, was reached by 20 patients (Responders). Efficacy was measured primarily as PSA nadir, and secondly as time to PSA nadir and prostate volume change. Safety was monitored throughout the whole study period. ;
