Conditions

Prostate Cancer

Brief summary

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.

Detailed description

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.

Inclusion criteria

1. Age ≥ 50 years, ≤ 75 years 2. Histologically confirmed localized (stage T1c, T2a-T2c) prostate cancer that is judged relevant for prostatectomy. 3. PSA value \< 20 ng/ml within 6 weeks before enrolment. 4. Gleason score ≤ 3+4 at diagnostic biopsy (or preferably with more precise method for judging the localization of the primary tumour focus (foci). 5. Adequate renal function: Creatinine \< 1.5 times upper limit of normal. 6. Adequate hepatic function: Aspartate Transaminase (ASAT), Alanine Transaminase (ALAT) and Alkalase Phosphatase (ALP) \< 1.5 times upper limit of normal. 7. Negative dipstick for bacteriuria. 8. Patient must have ability to cope with the study procedures and to return to scheduled visits including follow up visit. 9. Patients that has been scheduled for prostatectomy

Exclusion criteria

1. Ongoing or previous hormone therapy for prostate cancer. 2. On-going or previous therapy within 12 month of finasteride or dutasteride. 3. On-going or previous invasive therapy for benign prostate hyperplasia (TURP, TUMT). 4. Use of pace maker or other electronic devices 5. Symptoms or signs of acute prostatitis. 6. Symptoms or signs of ulcered proctitis 7. Severe micturation symptoms 8. On-going therapy with anticoagulant (e.g Warfarin. Other anticoagulant should be withdrawn 1 week before injection). 9. Concomitant systemic treatment with corticosteroids, or immune modulating agents. 10. Known immunosuppressive disease (e.g. HIV, diabetes). 11. 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.
