Summary
Brief summary (as posted)
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.
