A Randomized, Double-Blind, Placebo-Controlled Trial of the Safety and Efficacy of Ozarelix, in Patients With Lower Urinary Tract Symptoms(LUTS) Due to Benign Prostatic Hypertrophy (BPH)
This study is to compare the efficacy and safety of ozarelix 15 mg given intramuscular (IM) 2 weeks apart on the improvement of symptoms and the duration of improvement for up to 6 months in men with Benign Prostatic Hypertrophy (BPH) who are over 50 years of age.

Descripción detallada
This study is to compare the improvement in symptom scores, peak flow rate and quality of life in men suffering from lower urinary tract symptoms (LUTS) secondary to Benign Prostatic Hypertrophy (BPH) following treatment with ozarelix. Ozarelix is compared to placebo and injections given 14 days apart. Patients are followed for 6 months and both safety and efficacy assessed at monthly visits. Additionally, the impact of treatment on erectile function, if any, as well as Prostate-Specific Antigen (PSA) and Testosterone levels will be monitored.
The screening period of 7 days. The duration of the study is 40 weeks, including a 28-day placebo run-in phase (eligible participants entered a placebo run-in phase in which placebo is administered twice over a 2 week period [Day -28 and Day -14] and participants are assessed to establish baseline values approximately 14 days following the second placebo injection), study drug is administered on Days 0 and 14 followed by 34 weeks of observation after the last dose of study drug.

Change From Baseline in International Prostate Symptom Score (IPSS)
Periodo de tiempo: 12 weeks
|
IPSS is a validated self-administered index for grading benign prostatic hyperplasia (BPH)-related signs and symptoms.
It consists of a set of seven questions.
A total score of 1-7 indicates mild disease, 8-19 moderate disease and 20-35 severe disease.

International Prostate Symptom Score - Quality of Life (IPSS-QOL)
Periodo de tiempo: 36 weeks
|
IPSS QOL is a disease-specific quality of life question, referred to as IPSS Question 8. Participants with an IPSS QOL of <3 at screening will be excluded from this study.
The rating is as follows: 0=delighted, 1=pleased, 2=mostly satisfied, 3=mixed, 4=mostly dissatisfied, 5=unhappy, 6=terrible.

BPH Impact Index (BPHII)
Periodo de tiempo: 36 weeks
|
BPH Impact Index (BII) is used to assess the impact of BPH on various aspects of health.
This 4 question self administered index uses a scoring range from 0 (best) to 13 (worst).

|
Lower Urinary Tract Symptoms (LUTS) Global Assessment Question (LUTS-GAQ)
Periodo de tiempo: 36 weeks
|
The self administered LUTS GAQ is a "yes" or "no" response to a question asking whether overall improvement in LUTS will be observed during the treatment period.
|
36 weeks
|
|
International Index of Erectile Function-15 (IIEF-15)
Periodo de tiempo: 36 weeks
|
International Index of Erectile Function Erectile Function Domain (IIEF-EF) will be used to assess the effect of ozarelix on erectile function in sexually active men.
IIEF-EF is defined as the sum of the scores for Questions 1-5 and 15 of the IIEF questionnaire.
This recall instrument is self-administered by the participant.
Individual questions are graded from 1 to 5 with a maximum total score of 30.
Lower IIEF-EF scores represent diminished erectile function.
Men with a score of ≥ 26 are interpreted as having normal erectile function.
|
36 weeks
|
|
Maximum Urinary Flow Rate (Qmax)
Periodo de tiempo: 36 weeks
|
Qmax was measured by free flow uroflowmetry.
Qmax is defined as the peak urine flow rate (measured in milliliter (mL)/second using a standard calibrated flowmeter).
For a Qmax to be considered valid, the voided volume had to be at least 125 mL.
The uroflowmeter is to be calibrated weekly.
