An Efficacy and Safety Study With Licroca Depot, a Controlled Release Product, Injected Into the Prostate
An Efficacy and Safety Study With Licroca Depot, a Controlled Release Product, Injected Into the Prostate
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.
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.
Inclusion Criteria:

 1. Age ≥ 45years

 2. Histologically confirmed localized prostate cancer (T1-T2), predominantly in one side
 of the peripheral zone, verified by biopsy.

 3. PSA value < 20 ng/ml within 6 weeks before enrolment.

 4. Gleason score ≤ 3+4 at diagnostic biopsy

 5. Adequate renal function: Creatinine < 1.5 times upper limit of normal.

 6. Adequate hepatic function: ASAT, ALAT and ALP < 1.5 times upper limit of normal.

 7. Negative dipstick for bacturia.

 8. Patient must have ability to cope with the study procedures and to return to scheduled
 visits including follow up visit.

 Exclusion Criteria:

 1. Previous or ongoing hormone therapy for prostate cancer.

 2. Ongoing or previous therapy (within3 month) of finasteride or dutasteride.

 3. Ongoing or previous invasive therapy for benign prostate hyperplasia (TURP, TUMT).

 6. Severe micturation symptoms (I-PSS >17)

 7. Concomitant systemic treatment with corticosteroids, or immunomodulating agents.

 8. Known immunosuppressive disease (e.g. HIV, insulin dependent diabetes).

 9. Simultaneous participation in any other study involving not market authorized drugs or
 having participated in a study within the last 12 months prior to start of study
 treatment.
