Brief summary

This exploratory study will be conducted open label in a single investigational clinical unit. Altogether 52 patients with benign prostate hyperplasia (BPH) will be randomly assigned to receive 4 different treatments with degarelix.

Detailed description

The present study aims at exploring the potential of the currently available formulation of degarelix to treat BPH with only a short transient lowering of the serum testosterone concentration to or below the castration level defined as 0.5 ng/mL. Two doses and two dosing regimens (32 and 64 mg administered either as a single administration or as two administrations separated by 14 days) will be evaluated for 42 days.

Interventions

DRUGDegarelix

Two doses of 16 mg each administered as two administrations (separated by 14 days) will be evaluated for 42 days.

Inclusion criteria

Each patient must comply with all of the following inclusion criteria to be allowed to be randomised into the study: 1. Man, 55 to 75 years of age. 2. Clinical diagnose of BPH with a prostate volume more than 30 mL, a maximal uroflow of 12 mL/sec or less and an international prostate sympton score (IPSS) of 13 or more at screening. 3. A prostate specific antigen (PSA) value less than 10 ng/mL and no clinical evidence of adenocarcinoma of the prostate at screening. If a biopsy of the prostate is performed, a period of 6 weeks should be allowed after the biopsy before the patient is enrolled into the study. 4. Has a baseline testosterone level above 3 ng/mL at screening.

Exclusion criteria

Any patient meeting one or more of the following

Design outcomes

Primary

MeasureTime frameDescription
Interntional Iindes of Erectile Function (IIEF) Score: Overall SatisfactionDay 0-42The IIEF contains 15 items in 5 domains: Erectile Function (6 items), Orgasmic Function (2 items), Sexual Desire (2 items), Intercourse Satisfaction (3 items), and Overall Satisfaction (2 items). Item are scored on a scale from 'No sexual activity' to 'Almost always to always'. For the Erectile Function domain, a score of 1-10 indicates severe erectile dysfunction and 26-30 no dysfunction, the minimum score being 1 and the maximum 30. For all other domains, a higher score indicates less dysfunction. The IIEF does not yield a total score.
Post-void Residual Urine VolumeDay 0-42The post-void residual urine volume in the bladder was evaluated by transabdominal ultrasound. The urine bladder was sonicated from two directions perpendicular to one another, and the volume calculated automatically.
International Prostate Specific Symptom (IPSS) ScoreDay 0-42The IPSS is a patient-administered questionnaire containing seven items to evaluate symptoms of urinary obstruction (incomplete emptying, frequency, hesitancy, urgency, weak stream, straining, nocturia) over the preceding week. Each urinary symptom question is assigned points from 0 to 5 indicating increasing severity of the particular symptom. The total score can therefore range from 0 to 35 (0-7: mildly symptomatic; 8-19: moderately symptomatic; 20-35: severely symptomatic).
IPSS Global Quality of LifeDay 0-42Patients were asked about how they would feel if they were to spend the rest of their lives with their prostate symptoms just as they are now. The answers choices range from delighted to terrible or 0 to 6.
Time of Minimal Value of Testosterone (Tnadir)Day 0-42The time point when the lowest testosterone concentration was measured
Minimal Value of Testosterone (Cnadir)Day 0-42The lowest concentration of testosterone measured within the time frame

Number of Subjects With Testosterone Concentration at or Above the Baseline Interval ConcentrationDay 0-42The baseline interval concentration is 0.75 x baseline concentration
Prostate Specific Antigen (PSA) ConcentrationDay 0-42
Prostate VolumeDay 0-42The prostatic volume was measured by transrectal ultrasound. The prostatic gland was sonicated from two directions perpendicular to one another resulting in three cursor positions set by the urologist, and the volume automatically calculated.
Maximal Urinary FlowDay 0-42Urinary flow was determined by flowmetry using a device that fulfils the International Continence Society standards for maximum urinary flow.
